Question

I´m experimenting with if/elseif, and can´t understand why it won´t work this in a Drupal 6 template.

This code works:

<?php
    if ((arg(0) == 'node') && (arg(1) == 'add') || (arg(1) == 'edit')){
    $node = node_load(array('nid' => arg(1)));
    print '<h2>' .  $title . '</h2>';   }
?>

In case I´m in node/add/whatever or node/nid/edit it shows the title variable wrapped into h2´s.
Now, I want to show something slightly different in case node/add and node/edit.
So, I´ve tried this:

<?php
if ((arg(0) == 'node') && (arg(1) == 'edit')) {
    $node = node_load(array('nid' => arg(1)));
    print '<h3>' .  $title . '</h3>';
} elseif ((arg(0) == 'node') && (arg(1) == 'add')) {
    $node = node_load(array('nid' => arg(1)));
    print '<h2>' .  $title . '</h2>';   }
} else {
    echo ""; //it shows nothing
}
?>

And it won´t work (won´t show anything).
So, I´ve tried this:

<?php
    if ((arg(0) == 'node') && (arg(1) == 'add')){
    $node = node_load(array('nid' => arg(1)));
    print '<h2>' .  $title . '</h2>';   }
?>
<?php
    if ((arg(0) == 'node') && (arg(1) == 'edit')){
    $node = node_load(array('nid' => arg(1)));
    print '<h3>' .  $title . '</h3>';
    }
?>

And in this case, it works only with node/add, but completely ignores node/edit.

What am I doing wrong?
Thanks for your advice!

The path for a node edit page is node/[nid]/edit…you need to use arg(2) instead:

if ((arg(0) == 'node') && is_numeric(arg(1)) && (arg(2) == 'edit')){
