So im trying to run a PHP script that sets a deleted field in the database to poplulate if you drag a certain text element to the droppable area.

At the moment i have this droppable area:

<div class="dropbin" id="dropbin" >
    <span class="fa fa-trash-o noSelect hover-cursor" style="font-size: 20pt; line-height: 225px;">&nbsp;</span>
</div>

and this draggable text:

<div id='dragme' data-toggle='modal' data-target='#editNoteNameModal' class='display-inline'>" . $data['NoteName'] . "</div>

The area im having an issue with is this:

$("#dropbin").droppable
  ({
    accept: '#dragme', 
    hoverClass: "drag-enter",
    drop: function(event) 
    {
      var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>;
      var deletedby = <? if(isset($_SESSION['username'])){ echo $_SESSION['username'];} ?>
      var data = {noteid1: noteid, deletedby1: deletedby};

      if (confirm('Delete the note?')==true) 
      {
        $('#dragme').hide();
        debugger
        $.ajax({
          type: 'POST',
          url: 'deleteNote.php',
          datatype: 'json',
          data: data,
          success: function(result)
              {
                  alert("Success");
              }
        });

        window.location = ".php";
      }
      else
      {
        window.location = ".php";
      }
    }
  });

EDIT: The line i get the error on is:

var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>;

Im currently getting an "Unexpected token ;" and its stopping the droppable from working.

Just a side note, if i run it without the variables it hits everything apart from:

url: 'deleteNote.php',

Also inside deleteNote.php is this incase it helps:

<?php

include "connectionDetails.php";

?>

<?php

if (isset($_POST['noteid1'], $_POST['deletedby1'])) 
{
    $noteid2 = $_POST['noteid1'];
    $deletedby2 = $_POST['deletedby1'];

    // echo "Hello...". $noteid;

    $stmt = "UPDATE Notes SET Deleted = GETDATE() WHERE NoteID = (?)";
    $params = array($noteid2);

    $stmt = sqlsrv_query($conn, $stmt, $params);

    if ($stmt === false) 
    {
        die( print_r(sqlsrv_errors(), true));
    }
}

else
{
    echo "No Data";
}


?>

(I deliberatley don't have deletedby in the database just yet, ignore that)

Could anyone possibly help me to get this to work?

• what is that debugger? is that mented or is a mistake? – Exprator Commented Jul 27, 2017 at 10:39
• 1 var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>; apart from potential quoting issues, take a moment to think about what the result of that line will look like, if that POST parameter was not set ... – C3roe Commented Jul 27, 2017 at 10:40
• that is essentially a break point in the developer window in the console so i can see whether it is hitting that part of the code or not – Luke Litherland Commented Jul 27, 2017 at 10:40
• So the long JS script is inline code in a document that is always loaded via a POST request? Because if not, it's always going to end up as var noteid = ; – user5734311 Commented Jul 27, 2017 at 10:42
• 1 If the ajax success fired, it did successfully request the resource though. I always test my API and AJAX calls independently; if you change the type to GET you can simply put deleteNote.php?nodeid1=123&deletedby1=abc in the browser to test it. – user5734311 Commented Jul 27, 2017 at 10:50

Try to add quotes in these lines and add php after <? in second line:

var noteid = "<?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>";
var deletedby = "<?php if(isset($_SESSION['username'])){ echo $_SESSION['username'];} ?>";

OR

var noteid = "<?=isset($_POST['noteid']) ? $_POST['noteid'] : "" ?>";
var deletedby = "<?=isset($_SESSION['username']) ? $_SESSION['username'] : "" ?>";
