Code fails in plugin file but works in functions.php

Question

I want to use the following code in my main php plugin file. I get a whole screen full of error messages.

When I put it in functions.php it works fine. Can someone advise please?

$pages = get_posts($args);

foreach($pages as $page) {

    $out = get_permalink($page->ID);
}

You're passing in an array named $args, but you haven't included that in your question, can you edit your question to include the missing code? — Tom J Nowell

This is the complete code $args = array( 'orderby' => 'post_title', 'order' => 'ASC', 'post_type' => 'page', 'showposts' => 1000, 'caller_get_posts' => 1 ); $pages = get_posts($args); foreach($pages as $page) { $out = get_permalink($page->ID); } — I. Sher

You need to use a hook and a function in your plugin file. For example:

function sher_posts() {

    $pages = get_posts($args);

    foreach($pages as $page) {

        $out = get_permalink($page->ID);
    }
}
add_action('wp', 'sher_posts');

Of course this example doesn't know what $args are or what to do with $out.

while in general you should hook your code on an action or filter, I don't see any reason why should that code not work at plugin load time in the global context.
