I have an HTML table with entries on job information. The HTML is as follows:

<tr>

                            <td> <div contenteditable='true' class="edit" id="estimateNumber_<?php echo $row["estimateNumber"] ?>"><?php echo $row["estimateNumber"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="jobName_<?php echo $i ?>"><?php echo $row["jobName"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="generalContractor_<?php echo $i ?>"><?php echo $row["generalContractor"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="contact_<?php echo $i ?>"><?php echo $row["contact"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="jobStatus_<?php echo $i ?>"><?php echo $row["jobStatus"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="lastFollowUp_<?php echo $i ?>"><?php echo $row["lastFollowUp"] ?></div></td>

                            <td> <div contenteditable='true' class="edit" id="comments_<?php echo $i ?>"><?php echo $row["comments"] ?></div></td>

                            <?php $i++; ?>

                        </tr>

where $row is in a while loop of a SQL query.

I use Javascript as follows to send the information to update.php which is in the same folder:

$(document).ready(function(){

                        // Add Class

    $('.edit').click(function(){

    $(this).addClass('editMode');

    });



    // Save data

    $(".edit").focusout(function(){

        $(this).removeClass("editMode");

        var id = this.id;

        var split_id = id.split("_");

        var edit_id = split_id[1];

        var field_name = split_id[0];

        var value = $(this).text();



        $.ajax({

            url: 'update.php',

            type: 'post',

            data: {id:id, field:field_name, value:value},

            dataType: 'json',

            success:function(response){

            console.log(data); 

            }

        });

    });

    });

Yet in my update.php file it keeps saying that $_POST is empty. Where am I going wrong?
