Laravel使用AJAX将Javascript变量传递给PHP

Question

I am trying to pass a variable from my javascript code to the server side PHP code. I know this must be done via an ajax, But unfortunately I do not receive the value in the PHP variable in blade view.

form : url = facture=20

{!! Form::open(array('url'=> 'admin/facture=20', 'method'=>'post',   'name'=>'pushds')) !!}
{!! Form::hidden('ms_id', $fact->id) !!}
{!! Form::hidden('mstid', $fact->b_id, array('id' => 'mstid')) !!}     
{!! Form::close() !!}

jquery :

$('form[name="pushds"]').on('submit', function (e){
    e.preventDefault();

  var mstid = $('#mstid').val();
  var ms_id = $('#ms_id').val();

        $.ajax({
            type: 'post',
            url: 'facture=20',            
            data: {mstid: $('#mstid').val(), ms_id : $('#ms_id').val()},
            success: function( data ) {
......
},

the current page url : facture=20

the variable php in blade view

<?php 
if (!empty($_POST["mstid "])) {
echo $_POST['mstid ']; 
}
?>

Answer 1

Try this

In form ( Add id field to from )

{!! Form::hidden('ms_id', $fact->id, array('id' => 'ms_id')) !!}
{!! Form::hidden('mstid', $fact->b_id, array('id' => 'mstid')) !!} 

In AJAX

var mstid = $('#mstid').val(); # Calling through respective ID
var ms_id = $('#ms_id').val(); # Calling through respective ID

$.ajax({
    type: 'post',
    url: 'facture=20',            
    data: {mstid: mstid , ms_id : ms_id }, # passing variables 
    success: function( data ) {

Make sure your from submit reaches the AJAX code. You can test it by using alert() inside AJAX function ..

Answer 2

There are many methods to pass javascript value to server side using ajax:

Method 1:

Change your ajax code to:

From:

    $.ajax({
            type: 'post',
            url: 'facture=20',            
            data: {mstid: $('#mstid').val(), ms_id : $('#ms_id').val()},
            success: function( data ) {
......
},

To:

$.ajax({
            type: 'post',
            url: 'facture=20',            
            data: {mstid: $('input[name=mstid]').val(), ms_id : $('input[name=ms_id]').val()},
            success: function( data ) {
......
},

And on server side you can get it as :

<?php 
if (isset($_POST["mstid "]) && $_POST["mstid "] != "") {
echo $_POST['mstid ']; 
}
?>
