How can I get this id into a PHP variable after submit a form? I need to pass the total value to a PHP variable. Please help me to solve this problem.

<div class="table-responsive">
    <table class="table table-bordered">
        <tr>        
            <th>Total Price</th>
        </tr>
        <tr>                 
            <td>
                <input class="form-control1" type='text' id='txt_totalprice' name='txt_totalprice[]'/> 
            </td>
        </tr>
    </table>     
</div>

Total: <div id="totalvalue">0</div>  

Here is the script

<script type='text/javascript'>
    $('#totalvalue').click(function() {
        $.post("package.php", { 
            id: $(this).attr('id') 
        }, function(response) {
            alert(response);
        });
    });
</script>

• Which PHP variable? Or you want send the value in DIV with the ajax request? – Sougata Bose Commented Jul 7, 2016 at 10:13
• Your code is already doing what you require. Just use $_POST['id'] in your package.php page – Rory McCrossan Commented Jul 7, 2016 at 10:14
• yes i want to send div id value to php variable – think_user Commented Jul 7, 2016 at 10:14
• @RoryMcCrossan i didn't get post value in package.php – think_user Commented Jul 7, 2016 at 10:15
• In that case check the console to see if the request was sent and if there were any errors – Rory McCrossan Commented Jul 7, 2016 at 10:16

You want the value between the div tags, not the ID, correct?

Change this:

id: $(this).attr('id')

To this:

id: $(this).text()

If you want to display the value on the page do this:

Create an empty div:

<div id="saved-value"></div>

Place it anywhere you want on the page.

Then change your jQuery:

}, function(response) {
    $('#saved-value').html(response);
});

This is how you get the id value on your package.php Page.

   <?php 

     $_POST['id'];

    ?>

or you can just store the id in a new variable.

<?php 

$id = $_POST['id'] 
echo($id);
?>

if you arent sure if there are any values being sent by your post you can use this.

<?php 

//This will help you since Post is an array.
 print_r($_POST) 

?>
