Question

I have a MySQL database and with a php function i made a table is created to view the content.
Now i have an image (a little red cross). Now i want that if the user click’s on the image a delete query is executed. But i don’t know how.

$column = array_keys($array[0]);

 echo "<table border='1'>";
            echo "<tr>";
            foreach($column as $title)
            {

                echo "<td width='100px'>$title</td>";

            }
            echo "</tr>";

            echo "<tr>";
            foreach($array as $row)
            {
                foreach($row as $item)
                {
                    echo "<td>$item</td>";
                }

                 echo '<td><img src="delete_button.png value="'.$row['id'].'"" /></td>'; //the button and the id as value
                echo "</tr>";
            }

            echo "</table>";

Answer 1

You would have to put a link on the image as such

echo '<td><a href="delete.php?id='.$row['id'].'"><img src="delete_button.png" /></a></td>';

And then in your delete.php file or whatever other script you put, you retrieve the id with

$_GET["id"]

And you execute your query.

I hope your site is secured and that not everyone or every crawler and hit that link though, make sure it is safe, and I would recommend adding a confirm box at the very least.
