How can I pass $_GET variables from a link to a Bootstrap modal?

Passing $_GET Variables from a Link to a Bootstrap Modal

In web development, it's often necessary to pass data from a link to a modal window. To achieve this using $_GET variables in Bootstrap, follow these steps:

Simple Solution

  1. Modal Call Button:

    <td>
  2. Modal HTML:
    Place the following modal HTML outside the while loop on the page where the call button is located (preferably at the bottom):

    <div class="modal fade">
  3. file.php:

    <?php
    // Include database connection here
    
    $Id = $_GET["id"]; // Escape the string if you like
    
    // Run the query
    ?>
    
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times;</button>
      <h4 class="modal-title"><center>Heading</center></h4>
    </div>
    
    <div class="modal-body">
      // Show records fetched from database against $Id
    </div>
    
    <div class="modal-footer">
      <button type="button" class="btn btn-default">Submit</button>
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    </div>

Alternate Solution with Ajax

  1. Modal Call Button (with data attribute):

    <td>
  2. Modal HTML:

    <div class="modal fade">
  3. JavaScript (with jQuery):

    // jQuery library comes first
    // Bootstrap library
    $(document).ready(function() {
      $('#editBox').on('show.bs.modal', function(e) {
        var id = $(e.relatedTarget).data('id'); // Fetch id from modal trigger button
    
        $.ajax({
          type: 'post',
          url: 'file.php', // Here you will fetch records
          data: 'post_id=' + id, // Pass $id
          success: function(data) {
            $('.form-data').html(data); // Show fetched data from database
          }
        });
      });
    });
  4. file.php:

    <?php
    // Include database connection here
    
    if ($_POST['id']) {
      $id = $_POST['id'];
    
      // Run the query
      // Fetch records
      // Echo the data you want to show in the modal
    }
    ?>

Additional Notes

  • To eliminate the need for a separate script to clear data from the modal, you can use $('#editBox').on('hidden.bs.modal', function () { $(this).removeData('bs.modal'); });
  • Another option is to use jQuery's click function with $('.open-modal').click(function(){ ... });, where open-modal is a custom class added to the modal call button.
  • You can also pass on-page information to the modal using data attributes and handle it using the bootstrap modal event.

By using these techniques, you can effectively pass $_GET variables from a link to a Bootstrap modal, allowing you to display dynamic content in your web applications.
