PHP buttons to delete a row in MYSQL table output - php

Question

My goal is to display the entire table e.g SELECT * FROM athlete and include button for each row in the table output, that when pressed will remove that row from the database.
I have followed another post and shown below is what I have so far but does not work:
//if(isset($_POST['delete_id']) && (!empty($_POST['delete_id'])))
if(isset($_POST['Delete'])){
$delete_id = mysql_real_escape_string($_POST['delete_id']);
echo("deletebutton" . $delete_id);
//mysql_query("DELETE FROM KeepScores WHERE `id`=".$delete_id);
//header('Location: main.php');
}
else
{
$query = 'SELECT * FROM athlete';
$result = mysql_query($query);
$self = $_SERVER['PHP_SELF'];
$self = htmlentities($_SERVER['PHP_SELF']); // strip tags to improve security
echo("<table>
<tr>
<td> id </td>
<td>last name</td>
<td>first name</td>
<td>delete data</td>
</tr>");
while($row = mysql_fetch_array($result))
{
$id = $row['id'];
echo("<tr>");
echo("<td>" . $row['id'] . "</td>");
echo("<td>" . $row['lastName'] . "</td>");
echo("<td>" . $row['firstName'] . "</td>");
echo("<td> <form action='$self' method='post'>
<input type='hidden' name='delete_id value='$id' />
<input type='submit' value='Delete' />
</form>
</td>
</tr>");
}
mysql_free_result($result);
echo("</table>");
}
However this does not work. Does anyone know why. NOTE: I have left my login credentials out but I am connecting to the database elsewhere in the file.

Answer 1

The most probable cause is that your checking for $_POST['Delete'] having not given any of the submit buttons the attribute 'name' of 'Delete'. However, the line you have commented out above should work?

Answer 2

I think you should look into this areas
//if(isset($_POST['delete_id']) && (!empty($_POST['delete_id'])))
if(isset($_POST['Delete'])){
and
<input type='submit' value='Delete' />
You should include: <input type='submit' name="Delete" value='Delete' />
That should solve the problem.
