I have a php code that creates a list from the database. One of the items I retrieve from the database is the row id. I create the list in the following code:

    <th>Cover Name</th>
      <th>Sum Insured</th>
      <th>Info</th>
      <th style="width: 3.5em;"></th>
    </tr>
  </thead>
  <tbody>
  <?php while($row = mysql_fetch_array($query_set)) { ?>
    <tr>

      <td><?php echo $row['cover_name'] ?></td>
      <td><?php echo 'R '.$row['sum_insured'] ?></td>
      <td><?php echo $row['info'] ?></td>
      <td>
          <a href="cover-type.php?id=<?php echo $row['coverid']?>"><i class="fa fa-pencil"></i></a>
         <a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a>
      </td>
    </tr>
    <?php } ?>
      </tbody>
</table>

The syntax for calling #myModal

<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a>

as you can see the anchor #myModal and onclick

After clicking anchor I would like to pass $coverid to the following myModal pop up

    <div class="modal small fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
            <h3 id="myModalLabel">Delete Confirmation</h3>
        </div>
        <div class="modal-body">
            <p class="error-text"><i class="fa fa-warning modal-icon"></i>Are you sure you want to delete the cover?<br>This cannot be undone.</p>
        </div>
        <div class="modal-footer">
            <button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Cancel</button>
            <a href="delete-cover.php?id=<?php echo $coverid ?>" class="btn btn-danger"  >Delete</a>
        </div>
      </div>
    </div>
</div>

I under the impression that I need to have some form a hidden javascript variable in

<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a> and pass it to myModal window, but how do I do that ?

1. uses a single modal
2. use attribute data-id to store cover id: data-id="< ?php $coverid = $row['coverid'] ?>"
3. add class to trash icon, for example class="trash"
4. add id for Delete button in modal, for example id="modalDelete"

and in JQ:

// on clik trash icon    
$('.trash').click(function(){
    //get cover id
    var id=$(this).data('id');
    //set href for cancel button
    $('#modallCancel').attr('href','delete-cover.php?id='+id);
})

Change from

<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal">
    <i class="fa fa-trash-o"></i>
</a>

to

<a href="#myModal" class="trash" data-id="<?php echo $row['coverid']; ?>" role="button" data-toggle="modal">
    <i class="fa fa-trash-o"></i>
</a>

In your modal, you will get the id like this (for example):

<input id="feed_id" value="" />

Add:

$(document).ready(function () {
    $('body').on('click', '.trash',function(){
        document.getElementById("feed_id").value = $(this).attr('data-id');
            console.log($(this).attr('data-id'));
        });
    });
}

PHP is executed on server while JavaScript is executed on client. This code

<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal">...</a>

will actually transform into

<a href="#myModal" onclick="" role="button" data-toggle="modal">...</a>

because the PHP part didn't echo anything.

So, you'll rather have to so something like this:

<a href="#myModal" onclick="show_dialog('<?php echo $row['coverid']; ?>')" role="button" data-toggle="modal">...</a>

Assuming you have PHP variable $row defined and $row['coverid'] is, say, 1337, then this HTML will be rendered to browser:

<a href="#myModal" onclick="show_dialog(1337)" role="button" data-toggle="modal">...</a>

thus, if you define JavaScript function show_dialog, it will get called with value from $row['coverid']. The only way to pass variables from PHP to JavaScript is to echo their values from PHP in the place where you have JavaScript code.

A good practice for this is to use a <script> block somewhere on the top of your page with following content:

window.php_vars = window.php_vars || {};
window.php_vars.some_value = '<?php echo $some_value; ?>';
window.php_vars.some_other_value = '<?php echo $some_other_value; ?>';
window.php_vars.foo = '<?php echo 'bar'; ?>';

...but this approach works only for scalar types (ints, strings etc).
