I have a simple login form and have jQuery validate replacing the field labels when there's an error to display. The problem is that, once the error is cleared, the label disappears. I would like to find a way to revert back to the previous label's content, or rebuild that label when the field is valid...
Here's my code:
$(document).ready(function(){
$("#login").validate({
errorPlacement: function(error, element) {
element.prev().replaceWith(error);
},
rules: {
"email": {
required: true,
email:true,
},
"password": {
required: true,
minlength: 6
}
},
messages: {
email: {
required: "Please enter your email address.",
email: "Please enter a <u>valid</u> email address"
},
password: {
required: "Please enter your password.",
minlength: "Please enter a password with 6 characters or more."
}
},
});
});
And the HTML:
<form name="login" id="login" method="post" action="authenticate.php">
<p>
<label for="email">Email Address:</label>
<input type="text" name="email" id="email" class="required email" />
</p>
<p>
<label for="password">Password:</label>
<input type="password" name="password" id="password" class="required" />
</p>
<p>
<input type="submit" value="Log In" id="submit" />
</p>
In essence, when the user submits the form, if there's no data in the Email field, then the label for email gets replaced with the error. But once it has valid input, I want to put back the original label.
Thanks in advance for any suggestions,

I actually worked out a compromise whereby, instead of replacing the previous label with the error label, I'm appending a span into that label using error.appendTo(element.prev()) and errorElement: "span". Here's the new code:
$(document).ready(function(){
$("#login").validate({
errorElement: "span",
errorPlacement: function(error, element) {
error.appendTo(element.prev());
//element.prev().replaceWith(error);
},
rules: {
"email": {
required: true,
email:true,
},
"password": {
required: true,
minlength: 6
}
},
messages: {
email: {
required: " is Required",
email: " is Improperly Formatted"
},
password: {
required: " is Required",
minlength: " is not Long Enough"
}
},
});
});
It's less than ideal, but at least when the span appears, the error code is where I want it to be, and when it disappears, the label remains intact. I just made it so the label and the error complete each other like sentences... Eg, "Email Address" " is required." or "Email Address" " is not properly formatted."
Thanks to everybody that contributed here,

You can remove
errorPlacement: function(error, element) {
element.prev().replaceWith(error);
},
and the messages should appear beside the textboxes instead.
You can try to removeChild(label),and attach a new one to it when the error accur. Toggling the label seems to make sence

I have been trying many times with JQuery for validating errors using customized messages, but I am still confused that where I am making the mistake.I have tried with the normal validating messages, but when I tried with the customized, it shows me an error.
Below is the sample code which i have tried so far and unsucessful in executing it.
<form id="myform">
<tr>
<td class="alpha">username</td>
<td>
<input type="username" type="text" value="">
</td>
</tr>
<br/>
<tr>
<td class="alpha">postcode</td>
<td>
<input type="postcode" type="text" value="">
</td>
</tr>
<input type="submit" />
</form>
$.validator.setDefaults({
submitHandler: function() {
alert("submitted!");
}
});
$document.ready(function() {
$("#myform").validate({
rules: {
password: "required",
postcode: {
required: true,
minlength: 3
}
},
messages: {
username: {
required: "*Please enter a username",
minlength: "Your username must consist of at least 2 characters"
},
postcode: {
required: "Field PostCode is required",
minlength: "Field PostCode must contain at least 3 characters"
}
}
});
});
As written, your code would not work with the default messages either.
Please read my comments in the code...
rules: {
password: "required", // <- input with name="password" (where is "password"?)
postcode: { // <- input with name="postcode"
required: true,
minlength: 3
}
},
messages: {
username: { // <- input with name="username"
required: "*Please enter a username",
minlength: "Your username must consist of at least 2 characters"
},
postcode: { // <- input with name="postcode"
required: "Field PostCode is required",
minlength: "Field PostCode must contain at least 3 characters"
}
}
The rules and messages objects' parameters are keyed by the name attribute of the input element. Your input elements do not contain any name attributes. The plugin mandates that all form inputs contain a unique name, and the plugin will not work without these.
You have invalid values for the type attribute. There are no such things as type="username" and type="postcode"; and you erroneously have more than one type attributes on each input, <input type="username" type="text" value="">
In your case, you don't even attempt to define any rules for a username field. You only have password and postcode within the rules object.
Fix your invalid HTML markup and JavaScript...
Remove all extraneous type attributes from each input.
Add a unique name attribute to each input.
Only reference your name attributes within rules and messages objects.
DEMO: jsfiddle.net/2tx6u7wf/
My html code like this :
<form class="validatedForm" id="commentForm" method="get" action="">
<fieldset>
<input name="password" id="password" />
<input name="password_confirmation" />
</fieldset>
</form>
<button>Validate</button>
My javascript code to validate with jquery validate like this :
jQuery('.validatedForm').validate({
rules: {
"password": {
minlength: 6
},
"password_confirmation": {
minlength: 6,
equalTo : "#password"
}
},
messages: {
"password": 'Please enter a password, minimal 6 characters',
"password_confirmation": 'Please confirm your password'
},
});
Demo and full code like this : http://jsfiddle.net/oscar11/fEZFB/609/
If user input password : abcdef, then click button validate, there exist messsage : "Please confirm your password"
If user input password confirmation : ghijkl, there exist message : "Please confirm your password"
I want to change the message if user input password confirmation not same
The message like this : "confirm your password is not the same"
So there exist two message :
If user not input password confirmation, the message : "Please confirm your password"
If user input password confirmation, but not same with password, the message : "confirm your password is not the same"
How can I do it?
I think this will cover what you're looking for. You aren't limited to one message per input - you can set one for each rule on each input. I added a break in your HTML to make it more readable.
<form class="validatedForm" id="commentForm" method="get" action="">
<fieldset>
<input name="password" id="password" /><br/>
<input name="password_confirmation" id="password_confirmation" />
</fieldset>
</form>
<button>Validate</button>
Updated script:
jQuery('.validatedForm').validate({
rules: {
"password": {
minlength: 6,
required: true
},
"password_confirmation": {
equalTo: "#password"
}
},
messages: {
"password": {
minLength: "Password must be at least 6 charachters",
required: "Password is required."
},
"password_confirmation": {
equalTo: "The password and confimation fields don't match"
}
},
});
$('button').click(function () {
console.log($('.validatedForm').valid());
});
I added a required rule to the password so clicking validate with a blank form generates a message. I removed the minlength on the confirmation- it only needs to be equal to the password, and it has a minlength. Too short of a password has its own message, and when the password is long enough you'll get a different message when the confirmation field is empty or otherwise not equal to the password. You can see it in the fiddle here: http://jsfiddle.net/oscar11/fEZFB/609/
I have basic html and want to validate the fields with jQuery validator so I have less validation on php level. The form validates if all fields are empty and prevents submission to php but as soon as I complete 1 input the form sumits (even if all other fields are blank). All fields are required so I'm stumped - please help!
After some of your advice I have redone my validation on php level but it has the exact same effect. If all the fields are empty the validation works, as soon as 1 field is filled in the form submits.
jQuery: I ran it through JSLint and it yielded no errors - unbelievable right?!
$().ready(function () {
"use strict";
$('#register').validate({

},
email: {
required: true,
maxLength: 64,
email: true
},
password: {
required: true,
minLength: 6,

},
confirmPassword: {
required: true,
equalTo: "#password"
},
rsaid: {

digits: "Your ID number must consist of numerals only!"
}
},

errorLabelContainer: $('#errorContainer ul'),
wrapper: 'li'
});
});
html: Shouldn't be necessary but just in case :)

PHP code: This contains code for only the first 3 fields as password validation is long and irrelevant. The code returns no errors on phpcodechekcer.com.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["firstname"])) {
$firstnameErr = "First name is required";
} else {
$firstname = mysqli_real_escape_string($link, $_POST['firstname']);
}
if (empty($_POST["lastname"])) {
$lastnameErr = "Last name is required";
} else {
$lastname = mysqli_real_escape_string($link, $_POST['lastname']);
}
if (empty($_POST["email"])) {
$emailErr = "Email address is required";
} else {
if (!isValidEmail($_POST["email"])) {
$emailErr = "Email address is invalid";
} else {
$email = mysqli_real_escape_string($link, $_POST['email']);
}
}
}
better make validation on server side, if your client turn off javascript on browser then all data will send to server without any validation
It's to be need jquery file link on header of html.
Perhaps it's because you are not using fieldset enclosing?
On the other side, you may look towards plain HYML5 validation.
I'm trying to submit my form through Jquery, but the submit part of my code just doesn't work! And I can't see what's wrong with it.
<?php
if(!isset($_SESSION["useridentity"])){
die(header("Location:index.php"));
}
include("actions/connect.php");
$q = "SELECT username FROM users WHERE useridentity = '".$_SESSION["useridentity"]."'";
$r = mysql_query($q,$con);
$f = mysql_fetch_array($r);
?>
<div class="absolutedialog" id="login">
<form class="loginform" id="loginform" name="loginform" method="POST" action="actions/login.php">
<div class="label">
Welcome back, <b><?php echo $f["username"]; ?></b>. Please, type your password to confirm your identity.
</div>
<input class="loginformpassword" id="password" type="password" name="pass" maxlength="32"/>
<div id="passwordfail"></div>
<input class="regularbutton" id="submit" type="button" value="Submit"/>
<button class="grayregularbutton" id="gobacktoconsole" type="button">Go back</button>
</form>
</div>
<div class="blackoverlay"></div>
<script>
$(document).ready(function() {
$('#login').fadeIn(1000);
$('.blackoverlay').fadeIn(500);
//Destroy $_SESSION variables and go back to console
$('#gobacktoconsole').on('click',this, function(e) {
$(".absolutedialog").fadeOut(500);
$(".blackoverlay").fadeOut(1000);
window.setTimeout(
function() {
window.location.href="actions/logout.php";
},
1000
);
});
//Submit validations
$('#submit').on('click',this, function(e){
if($("#password").val() == "")
$("#passwordfail").html("Please, type your password");
else{
$("form#loginform").submit();
$(".absolutedialog").fadeOut(500);
$(".blackoverlay").fadeOut(1000);
}
});
//Clear password message error when something is typed in the password input
$('#password').on('keyup',this, function(e) {
$("#passwordfail").html("");
});
//Prevent default submit on enter, and click #submit button instead in order to execute validations
$('#loginform').bind("keyup keypress", function(e) {
var code = e.keyCode || e.which;
if(code == 13){
e.preventDefault();
$("#submit").click();
}
});
});
</script>
I tried adding return false; below $("form#loginform").submit(); but doesn't works. Am I missing something? Please, help!
Sorry for the lack of details; if you need me to add some more, please ask.
You have this element:
<input class="regularbutton" id="submit" type="button" value="Submit"/>
When you say
$("form#loginform").submit();
THe brpwser is assuming you're calling it, not the submit() method of the form object. Just change the id to something else.
<input class="regularbutton" id="submitButton" type="button" value="Submit"/>
The nastiest thing ever! Hope this helps.
I have seen many times problems about form submitting and form validation and I have found that the best way to do it is by using a simple open source jquery plugin such as jquery.validate.js.
This is an example about preventing default submit and posting data successfully to php file.
First you have to get these open source framework and you can use them whenever you want.
Files are three scripts :
<script src="js/jquery.min.js></script>
<script src="js/bootstrap.min.js"></script> <!-- open source framework twitter bootstrap -->
and one css file :
<link href="bootstrap/bootstrap.min.css" rel="stylesheet" media="screen">
example of code :
<form method="post" action="php/inscriptionAction2.php" class="form-horizontal" name="register" id="register">
// code of site inscription : name , email , password , confirmed password ....
<div class="form-group">
<div class="col-xs-offset-3 col-xs-9">
<div class="form-actions">
<input type="submit" class="btn btn-primary" name="newsubmit" id="newsubmit" value="Submit">
<input type="reset" class="btn btn-default" value="Reset">
</div>
</div>
</div>
</form>
and this is a simple script
$(document).ready(function(){
jQuery.validator.addMethod("lettersonly", function(value, element) {
return this.optional(element) || /^[a-z]+$/i.test(value);
});
$('#loginForm').validate({
rules: {
name: {
minlength: 2,
lettersonly:true,
required: true
},
lname: {
minlength: 2,
lettersonly:true,
required: true
},
username: {
lettersonly:true,
minlength: 2,
required: true
},
email: {
required: true,
email: true,
remote: {
url: '/setup/verify_email/',
cache: false
}
},
password: {
required: true,
minlength: 5,
maxlength: 250
},
password2: {
equalTo: '#password'
},
gender: {
required: true
}
},
messages: {
name: {
required:"Please enter your first name",
minlenght:"Your first name must consist of at least {0} characters",
lettersonly: "Letters only please"
},
lname: {
required:"Please enter your last name",
minlenght:"Your last name must consist of at least {0} characters",
lettersonly: "Letters only please"
},
username: {
lettersonly: "Letters only please",
required: "Please enter a username",
minlength: "Your username must consist of at least {0} characters"
},
email: {
required:"Please enter your email address",
email:"Please enter a valid email adress",
url:"Please enter a valid url",
cache:""
},
password: {
required: "Please provide a password",
minlength: "Your password must be at least {0} characters long",
maxlength: "Your password must be less than {0} characters long"
},
password2: {
equalTo: "Please enter the same passwords"
},
postal_code: "Please enter a valid zip code",
timezones: "Please select a time zone",
mp: "Please enter a valid mobile number. Only numbers please.",
gender: "Please select a gender",
dob: "Please enter a valid Date of Birth in mm/dd/yyyy format."
},
highlight: function (element, errorClass, validClass) {
$(element).closest('.control-group').removeClass('success').addClass('error');
},
unhighlight: function (element, errorClass, validClass) {
$(element).closest('.control-group').removeClass('error').addClass('success');
},
success: function (label) {
$(label).closest('form').find('.valid').removeClass("invalid");
},
errorPlacement: function (error, element) {
element.closest('.control-group').find('.help-block').html(error.text());
}
}).cancelSubmit=true; // to block the submit of this plugin and call submit to php file
By using two powerful frameworks, Twitter Bootstrap and jQuery , you can make your work faster and more professional.
For more details you can have a look at their documentation.
First you should import jquery
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
second change the id value of the button to anything else and will work, you may need to set timeout before submitting in order to delay the submit after the fadeout effect
I'm using this jquery validation plugin
<s:textfield cssClass="form-control input-default" name="contest.title" id="title" placeholder="Enter Title"
/>
Validation doesn't work for this, but if I change the name to title - validation works.
I tried searching, but couldn't find a means to validate fields with a . in their name.
Please help
Update
Script
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#contestform").validate({
submitHandler: function(form) {
// return false; // block the default submit action
},
rules: {
title: {
required: true
},
link: {
required: true
},
startdt: {
required: true
},
enddt: {
required: true
},
descr: {
required: true
},
},
messages: {
title: "Please enter a title",
link: "Please enter the sponser redirection link",
startdt: "Please select start date",
enddt: "Please select end date",
descr: "Please enter description"
}
});
});
</script>
Part of the form
<form action="" enctype="multipart/form-data" method="post" id="contestform">
<s:hidden name="option" value="option"/>
<s:hidden name="contest.idcontest"/>
<div class="form-group">
<label for="title">Title</label>
<s:textfield cssClass="form-control input-default" name="contest.title" id="title" placeholder="Enter Title"
/>
</div>
You need to put the field names in qoutes. From the plugin documentation
Fields with complex names (brackets, dots)
When you have a name attribute like user[name], make sure to put the
name in quotes. More details in the General Guidelines.
The sample in the linked reference:
$("#myform").validate({
rules: {
// no quoting necessary
name: "required",
// quoting necessary!
"user[email]": "email",
// dots need quoting, too!
"user.address.street": "required"
}
});
