Question

For some reason my if statements don’t work as expected.

$query = "SELECT title FROM blog";
$result = mysql_query($query);
$rows = mysql_num_rows($result);

for ($j = 0; $j < $rows; ++$j)
{
    if (isset($_POST['$j']))
    {
        $id  = mysql_real_escape_string($_POST['id']);
        $query = "DELETE FROM blog WHERE id='$id'";
        mysql_query($query);
        echo 'Deleted post.. ';
        echo '<a href="blog.php">Click here</a>';
    }
    else
    {
        echo 'Failed!';
    }
}

What happens is that “Deleted post..” and the “link” get echoed the number of rows I have in my table blog. Only one row in my table gets deleted though which is what I want. One button gets pressed each time, so shouldn’t it echo “Deleted post..” only one time and “Failed!” the rest of the times? Thanks =)

Note: I’m still new to programming, sorry if the question is stupid.

Note 2: I have many buttons on another page.. they are labeled by numbers ‘1, 2, 3’ etc.

change:

$_POST['$j'] // here, due to the single quotes you're
             // always testing for the literal `$j`, and not
             // the value of current loop iteration.

to:

$_POST[$j]
