How can I handle duplicate inputs name?

How can I handle duplicate inputs name? - javascript

I have a dynamic form which probably has duplicate input names.
$(".add_more_staff").on("click", function(){
var $newMember = $(this).siblings('.company_members').clone();
$newMember.insertBefore($(this));
})
a, input{
display: block;
margin-bottom: 5px;
}
input{
cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="#" method="post">
<div class="company_members">
<input class="staff_name" type="text" name="name" required placeholder="name" />
<input class="staff_mobile" type="text" name="mobile" required placeholder="mobile" />
<hr />
</div>
<input type="button" class="add_more_staff" value="Add more staff" />
<input type="submit" value="register_company_staffs" />
</form>
In the code above, you will have two inputs named mobile (or name) if you click on Add more staff button once.
Now I want to know, how should I get it in the PHP codes? According to some tests, $_POST['mobile'] contains the last input value. So how can I get all inputs value in PHP?
Should I make different names for new inputs in jQuery like name="mobile-n" (n = 1, 2 ..)
Should I use array-name for inputs like name="mobile[]" ?
Or what?

Try like this:
<div class="company_members">
<input class="staff_name" type="text" name="name[]" required placeholder="name" />
<input class="staff_mobile" type="text" name="mobile[]" required placeholder="mobile" />
</div>
in PHP:
$staff_names = $_POST['name'];
$staff_mobiles = $_POST['mobile'];

try this with jquery, during appending the html, you can add dynamic increment variable to like
staff_name_1, staff_name_2, staff_mobile_1, staff_mobile_2
with this, you can easily save or define the unique names, like I am showing you on simple example:
var a=0;
$(".add_more_staff").on("click", function(){
$(".company_members").each(function(){
a++;
$(".staff_name").attr('name', $(".staff_name").attr('name')+a);
});
});
Hope you can my idea.

Please try below it will contains data in groups, so you can easily loop it after post data and your JQuery code seems fine.
<div class="company_members">
<input class="staff_name" type="text" name="data[0][name]" required placeholder="name" />
<input class="staff_mobile" type="text" name="data[0][mobile]" required placeholder="mobile" />
</div>
<div class="company_members">
<input class="staff_name" type="text" name="data[1][name]" required placeholder="name" />
<input class="staff_mobile" type="text" name="data[1][mobile]" required placeholder="mobile" />
</div>

add dynamically generated fields from form

Hi guys i want to dynamically add a group of input fields when a button is pressed. This works with 1 group, but not with more than one. Here is my HTML:
<form action="address.php" method="POST">
<div id="list">
<input type="text" name="address" placeholder="Address">
<input type="text" name="suburb" placeholder="Suburb">
<input type="text" name="state" placeholder="State">
<input type="text" name="country" placeholder="Country">
<button id="addMore">Add Address</button>
</div>
</form>
I'm calling the addMore function with this javascript:
$(function(){
$("#addMore").click(function(e){
e.preventDefault();
$("#list").append("<input type="text" name="address" placeholder="Address"><input type="text" name="suburb" placeholder="Suburb"><input type="text" name="state" placeholder="State"><input type="text" name="country" placeholder="Country"><button id="addMore2">Add Address</button></div>");
});
});
I've added a button at the end with an id of addMore2 because i wanna generate a similar set of input controls but with different names. I want to call that id with this function:
$(function(){
$("#addMore2").click(function(e){
e.preventDefault();
$("#list").append("<input type="text" name="address2" placeholder="Address"><input type="text" name="suburb2" placeholder="Suburb"><input type="text" name="state2" placeholder="State"><input type="text" name="country2" placeholder="Country"><button id="addMore3">Add Address</button></div>");
});
});
... and then another set of controls with the function addMore3. Same as above, but with the number 3.
If i use each function alone, it works. But if i try to use all 3 together, it doesn't work. How can i dynamically reproduce a set of input controls with different names?

you could do something like this
$(var count = 0;
$("#addMore2").click(function(e){
e.preventDefault();
$("#list").append("<input type='text' name='address2'"+count+" placeholder="Address"><input type="text" name='suburb2'"+count+" placeholder="Suburb"><input type="text" name='state2'"+count+" placeholder="State"><input type="text" name='country2'"+count+" placeholder="Country"><button id='addMore3'"+count+">Add Address</button></div>");
count++;
});
});

#rayzor
You need to append your code before button
Please use below code:
jQuery("#addMore").click(function(e){
jQuery('<br><input type="text" name="address" placeholder="Address"><input type="text" name="suburb" placeholder="Suburb"><input type="text" name="state" placeholder="State"><input type="text" name="country" placeholder="Country">').insertAfter("input:last");
return false;
});
And remove code for $("#addMore2").click event

There's no need to add Addmore 2,3,etc manually. the js will add it automatically, as much as your want. Feel free to see this one: https://phppot.com/jquery/jquery-ajax-inline-crud-with-php/

Add multiple fields to form

I would like to add a function that generates multiple fields to my form.
This is how my form looks like:
<form action="form_sent.php" method="post">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
<button>Add more fields</button><br><br>
<input type="submit">
</form>
In my case I want 3 new fields (name, phone, email) when clicking on "Add more fields".
How can I do this?
https://jsfiddle.net/374cxt5s/

Try this: https://jsfiddle.net/Twisty/q8zj00s0/1/
HTML
<form action="form_sent.php" method="post">
<ul id="fieldList">
<li>
<input name="name[]" type="text" placeholder="Name" />
</li>
<li>
<input name="phone[]" type="text" placeholder="Phone" />
</li>
<li>
<input name="email[]" type="text" placeholder="E-Mail">
</li>
</ul>
<button id="addMore">Add more fields</button>
<br>
<br>
<input type="submit">
</form>
CSS
ul {
padding: 0;
margin: 0;
}
ul li {
list-style: none;
}
JQuery
$(function() {
$("#addMore").click(function(e) {
e.preventDefault();
$("#fieldList").append("<li> </li>");
$("#fieldList").append("<li><input type='text' name='name[]' placeholder='Name' /></li>");
$("#fieldList").append("<li><input type='text' name='phone[]' placeholder='Phone' /></li>");
$("#fieldList").append("<li><input type='text' name='email[]' placeholder='E-Mail' /></li>");
});
});
This allows you to store the results in array when you submit the form. Since you could have 5 names, phones, and emails, an array is the best way to address that. Then in PHP, you would have $_POST['name'][0] as the first one.

I'm assuming you probably want to create a dynamic form that allows you to add multiple contacts, etc.
CodePen Example
http://codepen.io/anon/pen/yeVRgw
The Basic HTML Setup
So that you can loop through things, and for sake of your own sanity, you'll probably want to segment out each chunk within the form. We'll also set up a hidden input to track how many partitions of name,phone,email have been created. We'll default at 1
<form action="form_sent.php" method="POST">
<input type="hidden" name="contacts" id="contacts" value="1">
<div class="form-contacts-container">
<div class="form-contact" id="form-contact-1">
<input type="text" name="name-1" id="name-1" placeholder="Name">
<input type="text" name="email-1" id="email-1" placeholder="E-mail">
<input type="text" name="phone-1" id="phone-1" placeholder="Phone">
</div>
<!-- We'll be adding additional inputs here -->
</div>
<div class="form-contacts-add">
<input type="button" value="Add More Fields" id="add-fields">
</div>
<div class="form-contacts-submit">
<input type="submit" name="submit" id="submit" value="Submit">
</div>
</form>
The JavaScript
This assumes you are using jQuery, so ensure that this is in your <head>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
Now we need to do a few things - firstly, attach an event listener to our button and secondly, add a new <div class="form-contact"> with included fields to our form. We'll also need to ensure that we're counting up to make sure each section has a unique name/id, and we'll increase the hidden input value to count how many contacts have been added in total.
<script type="text/javascript">
var total = 1; // Our default for how many contacts we have
$( document ).on( 'click', '#add-fields', function() {
var addBlockId = total = total + 1;
var addBlock = document.createElement('div');
$(addBlock).addClass('form-contact');
$(addBlock).attr('id','form-contact-' + addBlockId);
var inputName = document.createElement('input');
$(inputName).attr('type','text');
$(inputName).attr('name','name-' + addBlockId);
$(inputName).attr('id','name-' + addBlockId);
$(inputName).attr('placeholder','Name');
$(inputName).appendTo($(addBlock));
var inputEmail = document.createElement('input');
$(inputEmail).attr('type','text');
$(inputEmail).attr('name','email-' + addBlockId);
$(inputEmail).attr('id','email-' + addBlockId);
$(inputEmail).attr('placeholder','E-mail');
$(inputEmail).appendTo($(addBlock));
var inputPhone = document.createElement('input');
$(inputPhone).attr('type','text');
$(inputPhone).attr('name','phone-' + addBlockId);
$(inputPhone).attr('id','phone-' + addBlockId);
$(inputPhone).attr('placeholder','Phone');
$(inputPhone).appendTo($(addBlock));
$(addBlock).appendTo($('.form-contacts-container'));
$('#contacts').val(total);
});
</script>
Processing your Form
The last piece of the puzzle is to process your form properly. Not goign to give you all the answers here, but the basic logic would be to grab the $_POST['contacts'] value we've been updated and run a loop through to grab all of your inputs and associated values. For instance in PHP:
$total = $_POST['contacts'];
$contacts = array();
for( $i = 1; $i < $total; $i++ ) {
$this_contact = $array(
'Name' => $_POST['name-' . $i],
'Email' => $_POST['email-' . $i],
'Phone' => $_POST['phone-' . $i]
);
array_push($contacts, $this_contact);
}
var_dump( $contacts );

try something like this :
(function() {
var button=document.getElementById("add-user");
button.addEventListener('click', function(event) {
event.preventDefault();
var cln = document.getElementsByClassName("user")[0].cloneNode(true);
document.getElementById("users").insertBefore(cln,this);
return false;
});
})();
<form id="users" action="form_sent.php" method="post">
<div class="user">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
</div>
<button id='add-user'>Add more fields</button><br><br>
<input type="submit">
</form>
https://jsfiddle.net/9955n4fo/

It might not be a bad idea to wrap your input fields in a div just so when you append the other inputs they appear consecutively. Try something like this in your html
<form action="form_sent.php" method="post">
<div id="fields">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
</div>
<button>Add more fields</button><br><br>
<input type="submit">
</form>
and then your javascript can be completed as so
$(function() {
$('button').click(function() { addFields(); });
});
function addFields() {
var html = "<input name='name' type='text' placeholder='Name'><br>
<input name='phone' type='text' placeholder='Phone'><br>
<input name='email' type='text' placeholder='E-Mail'><br><br>";
$('#fields').append(html);
}

You need to implement jQuery to change the HTMLs DOM.
So, you add this in your <head></head> tags:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
You need to modify your HTML like this:
<form action="form_sent.php" method="post">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
<button extra="0">Add more fields</button><br><br>
<input type="submit">
</form>
Then you need to use this jQuery code:
<script>
$("button").on("click",function(){
var extra = $(this).attr("extra") + 1;
$("form").append("<input type='text' placeholder='Other Field' name='field' />");
$(this).attr("extra",extra);
}
</script>
This is the end!! :)

Try This :
Jquery append() function seems to sort out your answer
HTML Code should be as follow :
<form action="form_sent.php" method="post">
<div class = 'xyz'>
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
</div>
<button>Add more fields</button><br><br>
<input type="submit">
</form>
you JS should be as follow :
$(button).click(function(event){
$('.xyz').append("<input type ='text' class ='name' placeholder = 'Enter name'/><br/>");
$('.xyz').append("<input type='text' class='phone' placeholder='Enter phone'/><br/>");
$('.xyz').append("<input type='mail' class='phone' placeholder='Enter e-mail'/><br/>");
event.preventDefault();
});

This is how I would solve it.
HTML:
<form action="form_sent.php" method="post">
<div id="inputHolder">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
</div>
<button id="addMoreFields">Add more fields</button><br><br>
<input type="submit">
</form>
JS:
$( document ).ready(function() {
$("#addMoreFields").click(function(event) {
event.preventDefault();
$("#inputHolder").append('<input name="name" type="text" placeholder="Name"><br>');
$("#inputHolder").append('<input name="phone" type="text" placeholder="Phone"><br>');
$("#inputHolder").append('<input name="email" type="text" placeholder="E-Mail"><br><br>');
});
});

First you want to clone the elements you want to be adding. Do that when the page loads. Then when the button is clicked, clone the copy and add a copy to the page. And, you could either add type="button" to the button or use e.preventDefault() so your form does not get submitted when the button is clicked.
$(function() {
var inputs = $('form > button').prev().prev().prevUntil().clone().add('<br><br>');
$('form > button').on('click', function(e) {
e.preventDefault();
$(this).before(inputs.clone());
});
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form action="form_sent.php" method="post">
<input name="name" type="text" placeholder="Name"><br>
<input name="phone" type="text" placeholder="Phone"><br>
<input name="email" type="text" placeholder="E-Mail"><br><br>
<button>Add more fields</button><br><br>
<input type="submit">
</form>

Convert form with form arrays into a vaild json object

My form looks like this.
<form>
<input type="text" name="pic" value="test" />
<input type="text" name="person[0].name" value="Bob" />
<input type="text" name="person[0].age" value="25" />
<input type="text" name="person[1].name" value="Jim"/>
<input type="text" name="person[1].age" value="30" />
</form>
Is their a method that can take in any form and if the name of several form elements is the same then make them into an array under the initial name in json.
The json object would ideally look like
{
"pic" : "test",
"person":[
{"name":"Bob", "age":"25"},
{"name":"Jim", "age":"30"}
]
}

I found a library that handles this

Jquery .show Issue on IE

I have a form, and when certain inputs are filled another div will display beneath the form. The following is the code:
<form>
<div class="fieldtitle">Full Name:* </div><input type="text" value="" name="fullname" id="fullname" />
<div class="fieldtitle">Email:* </div><input type="text" value="" name="email" id="emailfield" />
<div class="fieldtitle">Contact No:* </div><input type="text" value="" name="contact" id="contact" />
</form>
<div id="demo1" style="width:300px; display:none;"></div>
<script type="text/javascript">
$("#formarea").keyup(function(){
if($(fullname).val() && $(emailfield).val() && $(contact).val() && $(quantity).val()) {
$("#demo1").show();
if($.browser.msie){
$('#demo1').css({"visibility":"visible"});
}
} else {
$("#demo1").hide();
}
});
</script>
It is working on all browsers, except for IE - any suggestions as how to solve this?

The html is missing the quantity field, which will cause logic issues in the Javascript.
<form>
<div class="fieldtitle">Full Name:* </div><input type="text" value="" name="fullname" id="fullname" />
<div class="fieldtitle">Email:* </div><input type="text" value="" name="email" id="emailfield" />
<div class="fieldtitle">Contact No:* </div><input type="text" value="" name="contact" id="contact" />
<div class="fieldtitle">Quantity:* </div><input type="text" value="" name="quantity" id="quantity" />
</form>
<div id="demo1" style="width:300px; display:none;">Test</div>
The Javascript binds the event to the wrong element. It should bind toinputs instead of the form. Also the selectors passed in for each input should be string literals using the css id selector.
$("input").keyup(function(){
if($("#fullname").val() && $("#emailfield").val() && $("#contact").val() && $("#quantity").val()) {
$("#demo1").show();
} else {
$("#demo1").hide();
}
});
There is also no need for the IE conditional. Jquery's show()/hide() methods are cross browser compatible.
Example: http://jsfiddle.net/DEfVS/1/

IE dont like suggested id or name selector, you dont use it in the right way. Specify which selector you are targetting.
e.g:
Replace
$(fullname)
With
$('#fullname')
And so on...
By the way, cannot see in your sample code any form with ID 'formarea'.
And remove this: if($.browser.msie){...} its useless.

jQuery serialize function with multple forms

I'm using the jQuery .serialize function and can't get it to serialize the proper form on submit.
my js code:
function getquerystring(form) {
return $("form").serialize();
}
my forms:
<div class="leave_message_box">
<form name="leave_message_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="leave_message" />
<input value="Leave Message" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "leave_message_form")'></p>
</form>
</div>
<div class="outside_job_box">
<form name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
I must be doing something wrong in passing the variable. the full code # pastie. The function I have does work, however, its always the last form that gets submitted.

Using this code:
$("form")
will find all the <form> elements in your document.
Given that form is a string containing the name of the form, what you want instead is this:
$("form[name='" + form + "']")
Looking at your supplied code, I have this suggestion. Instead of passing the form name to your function, why not just pass the form itself?
<button onclick="xmlhttpPost('blah', this.form)">
You also don't need to put javascript: in the onclick, onfocus, onwhatever properties.

I would suggest putting an ID attribute on the form and then using that ID as an explicit selector for jQuery:
<div class="outside_job_box">
<form id="outside_job_form" name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
Then you would select and serialize it like this;
var f = $("#outside_job_form").serialize();
Not only making your code more effecient but more readable, in my opinion.

If the sole purpose is to encode simple text into URL format then use encodeURIComponent().
