jquery

        function imageupload(thing_id) {         var form = new formdata($('.myform')[0]);         form.append('thing_id', thing_id);         // make ajax call         $.ajax({             url: 'uploadimages.php',             type: 'post',             xhr: function () {                 var myxhr = $.ajaxsettings.xhr();                 if (myxhr.upload) {                     myxhr.upload.addeventlistener('progress', progress, false);                 }                 return myxhr;             },             //add beforesend handler validate or             //beforesend: functionname,             success: function (res) {                 $('.content_here_please').html(res);             },             //add error handler when error occurs if want!             //error: errorfunction,             data: form,             cache: false,             contenttype: false,             processdata: false         });     }

php

$get_id = $_post['thing_id']; echo $get_id; // echoes id number of record when click anchor, there weird. list 10 records each page. if try make change on 2nd or 3rd record, modals show $get_id value.

one approach insert hidden field on form containing id want.

for instance,

<form id="myform"> ...other fields    <input type="hidden" name="thing_id" value="<?php echo $row['thing_id']; ?>"> </form>

and on server side, can access variable id 'thing_id' because you're sending form server on ajax call.
