如何将span标签的值放在php变量中

Question

I have <span id="count"></span> which is basically changing its value on click.

Part of my javascript code is

$( document ).ready(function() {

  $('#stars').on('starrr:change', function(e, value){
    $('#count').html(value);
  });      

});

How to store the value of id count in a variable in php.

I tried:

<?php $var = ?><span id="count"></span><?php ; ?>

But I am getting error.

I cant store it in hidden field because its value changing on click.

Is there a way such that When I click a "Post" button whatever the value of #count it get stored it in php variable so I can insert into database.

Thanks.

Answer 1

JavaScript is client side and PHP is server side

You must send your value to server with ajax

$(document).ready(function() {
    $('#stars').on('starrr:change', function(e, value) {
        $('#count').html(value);
        $.ajax({
            url: "saveVariable.php",
            data: {value:value}
        }).done(function() {

        });
    });

});

saveVariable.php

$var=$_REQUEST["value"];

Try like this...

$value = "<script type='text/javascript'> $('#count').html();</script>"; ?>
echo $value;
