how to get an array post values

In my script, I have input fields which are added dynamically. I have to get all input values using php but the problem in that $_POST['poids'] give me just the first value of input array, so just the first element of the array poids. This is my code:
$(function() {
var max_fields = 10;
var $wrapper = $(".container1");
var add_button = $(".add_form_field");
$(add_button).click(function(e) {
e.preventDefault();
const vals = $("> .item input[name^=poids]", $wrapper).map(function() {
return +this.value
}).get()
const val = vals.length === 0 ? 0 : vals.reduce((a, b) => a + b);
if ($("> .item", $wrapper).length < max_fields && val < 100) {
const $form_colis = $(".item").first().clone();
$form_colis.find("input").val("");
$wrapper.append($form_colis); //add input box
} else {
var err_msg = 'limit riched';
//alert(err_msg);
window.alert(err_msg);
}
});
$wrapper.on("click", ".delete", function(e) {
e.preventDefault();
$(this).parent('div').remove();
})
});
<div class="container1" style="min-height:200px">
<button class="add_form_field">Add New Field ✚</button>
<form method="post" action="postForm.php">
<div class="item">
<input type="text" placeholder="Poids" name="poids[]">
<input type="text" placeholder="Longueur" name="longueurs[]">
<input type="text" placeholder="Largeur" name="largeurs[]">
<input type="text" placeholder="Hauteur" name="hauteurs[]">
Delete
</div>
<button type="submit" name="" class="btn btn-danger btn-responsive "> Send </button></center>
</a>
</form>
</div>
to get post (postForm.php):
$poids = $_POST['poids'];
foreach($poids as $poid) {
echo " -->" .$poid;
}
I hope that you undestand what I mean.
Thank you in advance

The problem is that you're appending the div with the new input fields to $wrapper, but that's outside the form. You need to put it inside the form.
Change
$wrapper.append($form_colis); //add input box
to
$('.item', $wrapper).last().after($form_colis); //add input box

I'm no PHP expert, but by just browsing the code provided, it seems you're just searching for inputs with a name value of poids.
const vals = $("> .item input[name^=poids]",$wrapper).map(function() { return +this.value }).get()
Then when you create a bew input, you do not append poids to the input name.
const $form_colis = $(".item").first().clone();
$form_colis.find("input").val("");
$wrapper.append($form_colis);
Therefore, you will only find one with your method, and that's this one:
<input type="text" placeholder="Poids" name="poids[]">
So to solve this, inside the $form_colis method, add poids to it I do believe.

Validate checkbox with AngularJs

Again i'm having trouble with checkboxes. I'm getting info from an API and showing like checkbox. The problem comes when i'm triying to add a validation. This is a part of my code:
(function() {
'use strict';
var fact = {
templateUrl: './app/components/fact.components.html',
controller: factCtrl
};
angular.module('fApp').component('odcFacturas', fact);
factCtrl.$inject = ["$scope", "couponApi"];
function factCtrl($scope, couponApi) {
var vm = this;
vm.clientOrder = null;
vm.all = false;
vm.sendData = function() {
vm.apiData = couponApi.get({
idOrder: vm.idOrder
}).$promise.then(function(data) {
for (var i = 0; i < data.Response.length; i++) {
data.Response[i].Select = vm.all;
}
vm.coupons = data.Response;
vm.combo = data.Response.length > 0;
});
}
Here i call the info, and the next part of my code check all the checkboxes:
vm.selectAll = function() {
for (var i = 0; i < vm.coupons.length; i++) {
vm.coupons[i].Select = vm.all;
}
if (vm.all == 0) {
alert("Select at least one coupon");
}
}
How can I trigger three validations with a submit button? I mean: what I want to do is validate three cases:
if the checkbox "select all checkboxes" is checked, submit
if there's no selected checkboxes, show the alert message
if there's at least one checkbox (or 'n' checkboxes) selected,
submit
On the HTML view i have this:
<div class ="container-fluid">
<div class="row">
<div class="col-md-6">
<div class="cbx input-group">
<div class="checkbox" name="imtesting" ng-show="$ctrl.coupons.length > 0">
<label><input type="checkbox"
ng-show="$ctrl.coupons.length > 0"
name="allCoupons"
ng-model="$ctrl.all"
ng-click="$ctrl.selectAll()"/>Select all coupons</label>
<ul>
<li ng-repeat="c in $ctrl.coupons">
<input type="checkbox"
name="couponBox"
ng-model="c.Select"
ng-click="$ctrl.result()"
required/>{{c.CodeCoupon}}
<br>
</li>
</ul>
<label class="label label-danger" ng-show="submitted == true && !ctrl.newTest()">Select at least one coupon</label>
</div>
</div>
</div>
</div>
Hope you can help me.
Thanx in advance.

You can use the Select property from each coupon object like
vm.canSubmit = function() {
for(var i = 0; i< vm.coupons.length; i++)
{
if (vm.coupons[i].Select) {
return true;
}
}
return false;
}

Redo the way you are handling your selectsAll function. When you are using angular there is a thing called scope.$apply that is actually running which tells the dom to update if the object or properties have changed. Sometimes if you use for loops the way you are using them it wont register a change.
Try this and it should work:
vm.selectAll = function()
{
vm.all = !vm.all;
vm.coupons.forEach(function(o){
o.Select = vm.all;
})
}
vm.submit = function(){
var checked = 0;
vm.coupons.forEach(function(o){
if(o.Select === true)
checked +=1;
})
if(vm.all || checked > 0){
//submit here
}
else if(checked === 0){
//error
}
}
This will work both ways. If checked it will check all and if unchecked it will uncheck all. That validation will work for all three scenarios.

Javascript/jQuery form validation

I got most of this form validation to work properly but the only issue is that when the form detects an error on submit and the user corrects the mistake, the error text won't go away. This can be confusing for the user but I can't seem to figure out a way to make the error text disappear with the way that I am doing this. Also I know I have the option of PHP validation but there is a few reasons why I want to use this front end validation. Here is the whole validation script for the form. The submit portion is at the bottom:
JavaScript/jQuery
var valid = 0;
function checkName(elem) {
//gather the calling elements value
var val = document.getElementById(elem.id).value;
//Check length
if (val.length<1) {
document.getElementById("errorName").innerHTML = "<span>Don't forget your name.</span>";
} else if (val.length>40){
document.getElementById("errorName").innerHTML = "<span>This doesn't look like a name.</span>";
//If valid input increment var valid.
} else {
document.getElementById("errorName").innerHTML = "";
valid++;
}
}
function checkEmail(elem) {
var val = document.getElementById(elem.id).value;
//Check email format validity
var re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if (!re.test(val)) {
document.getElementById("errorEmail").innerHTML = "<span>Please enter a valid email.</span>";
} else {
document.getElementById("errorEmail").innerHTML = "";
valid++;
}
}
function checkMessage(elem) {
var val = document.getElementById(elem.id).value;
if (val.length<1) {
document.getElementById("errorMessage").innerHTML = "<span>It looks like you forgot the message.</span>";
} else if (val.length>2000) {
document.getElementById("errorMessage").innerHTML = "<span>It looks like your message is too long.</span>";
} else {
document.getElementById("errorMessage").innerHTML = "";
valid++;
}
}
//Contact: jQuery check for null/empty/errors
$(document).ready(function() {
function checkSubmit() {
if (valid == 3) {
document.getElementById("errorSubmit").innerHTML = "";
}
}
//If errors when submitting display message
$('#form13').submit(function(submit) {
if ($.trim($("#name").val()) === "" || $.trim($("#email").val()) === "" || $.trim($("#message").val()) === "") {
document.getElementById("errorSubmit").innerHTML = "<span>Please fill out all the form fields.</span>";
submit.preventDefault();
} else if (valid < 3) {
document.getElementById("errorSubmit").innerHTML = "<span>Please check the errors above.</span>";
submit.preventDefault();
}
})
});

Simply put your check on onChange event callback, if:
var x = getElementById("formid"); // then add a listener
x.addEventListener('change', function () {
callback with your code that examines the form
});
Or listen for a specific text box change event, that would be the simplest way, and look for a way to disable submit if the conditions aren't met.

Add an onchange event to your text inputs that will remove the error message.
Rather than making a count of valid fields, I would also check for the existence of error messages. This will make it easier to add more fields to your form.
function checkName(e) {
//gather the calling elements value
var val = $(e.target).val();
//Check length
if (val.length<1) {
document.getElementById("errorName").innerHTML = "<span class="errmsg">Don't forget your name.</span>";
} else if (val.length>40){
document.getElementById("errorName").innerHTML = "<span class='errmsg'>This doesn't look like a name.</span>";
//If valid input increment var valid.
} else {
document.getElementById("errorName").innerHTML = "";
}
}
function checkEmail(e) {
var val = $(e.target).val();
//Check email format validity
var re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if (!re.test(val)) {
document.getElementById("errorEmail").innerHTML = "<span class='errmsg'>Please enter a valid email.</span>";
} else {
document.getElementById("errorEmail").innerHTML = "";
}
}
function checkMessage(e) {
var val = $(e.target).val();
if (val.length<1) {
document.getElementById("errorMessage").innerHTML = "<span class='errmsg'>It looks like you forgot the message.</span>";
} else if (val.length>2000) {
document.getElementById("errorMessage").innerHTML = "<span class='errmsg'>It looks like your message is too long.</span>";
} else {
document.getElementById("errorMessage").innerHTML = "";
}
}
//Contact: jQuery check for null/empty/errors
$(document).ready(function() {
$('#name').change(checkName);
$('#email').change(checkEmail);
$('#message').change(checkMessage);
function checkSubmit() {
if ($('form .errmsg').length > 0) {
document.getElementById("errorSubmit").innerHTML = "";
}
}
}
/If errors when submitting display message
$('#form13').submit(function(submit) {
if ($.trim($("#name").val()) === "" || $.trim($("#email").val()) === "" || $.trim($("#message").val()) === "") {
document.getElementById("errorSubmit").innerHTML = "<span class='errmsg'>Please fill out all the form fields.</span>";
submit.preventDefault();
} else if ($('form .errmsg').length > 0) {
document.getElementById("errorSubmit").innerHTML = "<span class='errmsg'>Please check the errors above.</span>";
submit.preventDefault();
}
})
});
Since you were already using jQuery, I modified the code to use more of the jQuery functionality to make things easier. Now when a form field is modified and the element loses focus, the validation will occur immediately. We also no longer need to know how many error messages could potentially appear (though you never had a decrement operation for corrected values so the valid could become greater than 3). Instead we just make sure that there isn't more than 0 of them.

I've removed your onblur html attributes and replaced them by JavaScript keyup events. This will allow your script to check everything as soon as the user type something :
document.getElementById("message").addEventListener('keyup', function () {
checkMessage(this);
});
document.getElementById("email").addEventListener('keyup', function () {
checkEmail(this);
});
document.getElementById("name").addEventListener('keyup', function () {
checkName(this);
});

Find empty input elements inside a collection - jQuery

I am trying to find the empty input types like textbox, select and li elements inside a jQuery resultset.
My resultset is (requiredfields) -
$requiredFields = $(".f-form-required.f-form-field").filter(function(){
if($(':input:not([type="hidden"])'))
return $(this);
});
And on that resultset I want to query for empty inputs like textbox, select and li elements. But it seems I am doing something wrong. Can someone suggest me how to do that.
Currently I am doing this to get empty textboxes but not working -
var emptyInputs = 0;
$requiredFields.filter(function(){
$('input[type=text]').each(function(){
if (this.val == "") {
emptyInputs = emptyInputs + 1;
}
});
});
I am trying to do same for finding out empty dropdown/select elements and list / li elements over $requiredFields collection.

There is no val property. Try using .val() instead or this.value:
var emptyInputs = 0;
$requiredFields.filter(function(){
$('input[type=text]').each(function(){
if (jQuery(this).val() == "") {
emptyInputs = emptyInputs + 1;
}
});
});
or:
var emptyInputs = 0;
$requiredFields.filter(function(){
$('input[type=text]').each(function(){
if (this.value == "") {
emptyInputs = emptyInputs + 1;
}
});
});

I think you arn't using .filter() quite as it is expected to be used. Consider something like this:
<html>
<body>
<div>
<input type="text" id="text1" class="f-form-required f-form-field" />
<input type="text" id="text2" class="f-form-required f-form-field" value="test" />
<input type="text" id="text3" class="f-form-required f-form-field" />
</div>
</body>
</html>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
function test(){
var $requiredFields = $('.f-form-required.f-form-field');
var $errorFields = $requiredFields.filter(function () {
var $this = $(this);
return $this.is('input') && $this.val() === '';
});
var errorCount = $errorFields.length;
console.log('errors:' + errorCount);
}
$(document).ready(function(){
test();
}
</script>

input box not working in firefox

I am trying to have a basic filter when someone puts a word into a input box and list items hide on click, this is working fine in chrome but in firefox it is not working at all.
html:
<form ACTION="#" id="navsform" class="my-search">
<input id="formwidth" type="text" name="query" placeholder="Search...">
<input type="submit" class="my-button" value="Search" onclick="query_searchvar()"></form>
javascript:
function query_searchvar()
{
var searchquery=document.navsform.query.value.toLowerCase();
if(searchquery == '')
{alert("No Text Entered");
}
var queryarray = searchquery.split(/,|\s+/);
event.preventDefault();
$('li').each(function() {
var searchtags = $(this).attr('data-searchtags');
//alert(searchtags);
var searcharray = searchtags.split(',');
//alert(searcharray);
var found = false;
for (var i=0; i<searcharray.length; i++)
if ($.inArray(searcharray[i], queryarray)>-1) {
found = true;
break;
}
if (found == true )
{
$(this).show("normal");
}
else {
$(this).hide("normal");
}
});
}
Any help much appreciated. Thank you.
Hi, I managed to get this working with a combo of all your comments and some jquery resources:
HTML:
<form id="myform" action="#" class="my-search">
<input id="formwidth" type="text" name="query" placeholder="Search..." />
<input class="my-button" type="submit" value="Search" />
</form>
$('#myform').submit(function() {
var searchquery = String($('#myform input[name=query]').val()).toLowerCase();
if (searchquery == '') {
alert('No Text Entered');
}
var queryarray = searchquery.split(/,|\s+/);
$('li').each(function() {
var searchtags = $(this).attr('data-searchtags');
var searcharray = searchtags.split(',');
var found = false;
for (var i = 0; i < searcharray.length; i++)
if ($.inArray(searcharray[i], queryarray) > -1) {
found = true;
break;
}
if (found == true) {
$(this).show('normal');
}
else {
$(this).hide('normal');
}
});
return false;
});

document.navsform.query.value ???
onclick="query_searchvar()" ???
event.preventDefault ??? -- lack crossbrowser
Why Use click rather than submit?
missing return false?
why use it?
You're already using jQuery, it would be better to work 100% with Jquery?
<form ACTION="#" id="navsform" class="my-search">
<input id="formwidth" type="text" name="query" placeholder="Search...">
<input type="submit" class="my-button" value="Search"></form>
Javascript:
$(document).ready(function(){
$("#navsform").submit(function(event){
event = event||window.event; //Cross
var searchquery=String($("#navsform input[name=query]").val()).toLowerCase();
if(searchquery == ''){
alert("No Text Entered");
}
var queryarray = searchquery.split(/,|\s+/);
event.preventDefault();
$('li').each(function(){
var searchtags = $(this).attr('data-searchtags');
//alert(searchtags);
var searcharray = searchtags.split(',');
//alert(searcharray);
var found = false;
for (var i=0; i<searcharray.length; i++){
if ($.inArray(searcharray[i], queryarray)>-1) {
found = true;
break;
}
}
if (found == true ){
$(this).show("normal");
} else {
$(this).hide("normal");
}
});
});
return false;//prevents sending the form, remove if necessary.
});

There are a few things, you should change:
Pass in the event object to the handler function.
Attach the eventhandler to the form submit event, not the button. This way the return key will work.
Then you should use a tool like Firebug, Dragonfly or similar. It helps a lot. As mentioned in the comments, you could have found your error.
See Guilherme Nascimento's answer for an example. (But ignore the tone..)
