How to Implement a Delete Button to Remove Rows from a MySQL Table Using PHP?

Add a Delete Button to Remove Rows from MySQL Table Using PHP

To add a delete option to a MySQL table row displayed in an HTML table, you can follow these steps:

  1. Retrieve MySQL Data: Fetch the data from the contacts table using a query like:
<code class="php">$contacts = mysql_query("
        SELECT * FROM contacts ORDER BY ID ASC") or die(mysql_error());</code>
  1. Create a Table with Delete Buttons: Output the table with the data, adding a delete button in the last column:
<code class="php"><table id=&quot;contact-list&quot;>
    <thead>
        <tr>
            <th>Name</th>
            <th>Email</th>
            <th>Telephone</th>
            <th>Address</th>
            <th>Delete</th>
        </tr>
    </thead>
    <tbody>
        //Iterate results and display data
        <?php while( $contact = mysql_fetch_array($contacts) ) : ?>
            <tr>
                <td><?php echo $contact['name']; ?></td>
                <td><?php echo $contact['email']; ?></td>
                <td><?php echo $contact['telephone']; ?></td>
                <td><?php echo $contact['address']; ?></td>
                <td>
                    <form action='delete.php' method=&quot;post&quot;>
                        <input type=&quot;hidden&quot; name=&quot;name&quot; value=&quot;<?php echo $contact['name']; ?>&quot;>
                        <input type=&quot;submit&quot; name=&quot;submit&quot; value=&quot;Delete&quot;>
                    </form>
                </td>                
            </tr>
        <?php endwhile; ?>
    </tbody>
</table></code>
  1. Create a Delete Script: In delete.php, process the submitted data:
<code class="php">$query = "DELETE FROM contacts WHERE name={$_POST['name']} LIMIT 1";
// Execute the query to delete the record
mysql_query ($query);

// Handle success/failure scenarios
if (mysql_affected_rows() == 1) { 
    // Success: Contact deleted
    echo "<strong>Contact Has Been Deleted</strong><br /><br />";
} else { 
    // Failure: Deletion failed
    echo "<strong>Deletion Failed</strong><br /><br />";
} </code>
  1. Pass Name Value: In the HTML table, pass the name value to the delete.php script using a hidden field or pass it in the URL:
<code class="php"><form action='delete.php?name=&quot;<?php echo $contact['name']; ?>&quot;' method=&quot;post&quot;>
    <input type=&quot;hidden&quot; name=&quot;name&quot; value=&quot;<?php echo $contact['name']; ?>&quot;>
    <input type=&quot;submit&quot; name=&quot;submit&quot; value=&quot;Delete&quot;>
</form></code>
