I have a PHP file manage-users.php which contains bootstrap Data-table. Which shows data from MySQL users Table . code of Data-table is :
<table id="myTable" class="table table-striped table-hover">
<thead>
<tr>
<th>
<span class="custom-checkbox">
<input type="checkbox" id="selectAll">
<label for="selectAll"></label>
</span>
</th>
<th>First Name</th>
<th>Last Name</th>
<th>Email</th>
<th>Phone</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
<?php
$result = mysqli_query($conn,"SELECT * FROM users") or die("Unable to qet all users data " . mysqli_error($conn));
while ($row = mysqli_fetch_assoc($result)) {
echo "<tr>";
echo '<td>
<span class="custom-checkbox">
<input type="checkbox" id="checkbox1" name="options[]" value="1">
<label for="checkbox1"></label>
</span>
</td>';
echo "<td>".$row['FIRST_NAME']."</td>";
echo "<td>".$row['LAST_NAME']."</td>";
echo "<td>".$row['EMAIL']."</td>";
echo "<td>".$row['PHONE']."</td>";
echo '
<td>
<a href="#editEmployeeModal" class="edit" data-toggle="modal"><i class="material-icons" data-toggle="tooltip" title="Edit"></i></a>
<a href="#deleteEmployeeModal" class="delete" data-toggle="modal"><i class="material-icons" data-toggle="tooltip" title="Delete"></i></a>
</td>
';
echo "</tr>";
}
?>
</tbody>
</table>
In the same page, I have two bootstrap modals to delete and edit data . I'm working on Delete now.
Delete Modal Code is :
<div id="deleteEmployeeModal<?php echo $row['USER_ID']; ?>" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<form>
<div class="modal-header">
<h4 class="modal-title">Delete User</h4>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<div class="modal-body">
<p>Are you sure you want to delete these Records?</p>
<p class="text-warning"><small>This action cannot be undone.</small></p>
</div>
<div class="modal-footer">
<input type="button" class="btn btn-default" data-dismiss="modal" value="Cancel">
<button class="btn btn-danger"><a href="delete_user_data.php?id=<?php echo $row['USER_ID']; ?>">Delete</a></button>
</div>
</form>
</div>
</div>
</div>
Now the problem is that, that i can not delete data because in Delete Modal the $row['USER_ID
] is empty. there is no problem in retrieving data from the server because the $row['USER_ID
] is showing showing on every user specific delete button. what should i do now ?
If question needs more explanation, i'll explain.

Upon opening the modal, you basically set a hidden field so that when you submit the form, it will send delete_user_data.php?id=YOUR-VALUE
.
1) Store the ID in the HTML. A good place might be the link that opens the modal. Also, remove data-toggle
attribute because we will be opening the modal dynamically.
echo '<a href="#deleteEmployeeModal" class="delete" data-id="' . $row['USER_ID'] . '"><i class="material-icons" data-toggle="tooltip" title="Delete"></i></a>';
2) Only use one modal for deleting.
<div id="deleteEmployeeModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<!-- give your form an action and method -->
<form action="delete_user_data.php" method="GET">
<div class="modal-header">
<h4 class="modal-title">Delete User</h4>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<div class="modal-body">
<p>Are you sure you want to delete these Records?</p>
<p class="text-warning"><small>This action cannot be undone.</small></p>
</div>
<div class="modal-footer">
<!-- add a hidden input field to store ID for next step -->
<input type="hidden" name="id" value="" />
<input type="button" class="btn btn-default" data-dismiss="modal" value="Cancel">
<!-- change your delete link to a submit button -->
<button class="btn btn-danger" type="submit">Delete</button>
</div>
</form>
</div>
</div>
</div>
3) Open the modal dynamically.
$(function () {
$('a.delete').click(function (e) {
e.preventDefault();
var link = this;
var deleteModal = $("#deleteEmployeeModal");
// store the ID inside the modal's form
deleteModal.find('input[name=id]').val(link.dataset.id);
// open modal
deleteModal.modal();
});
});
Use similar approach for doing the Edit modal.
