Strict Standards error on file upload

Once a file is uploaded to a file field and the page/post is saved, I get this warning:

Strict Standards: Only variables should be passed by reference in …/wp-content/plugins/advanced-custom-fields/core/fields/file.php on line 83

This is on the latest update (4.2.0) and the file I was uploading was a .zip file. If it helps, the field was located on the options plugin page.

Cheers

Hi @markgdyr

Thanks for the bug report.

Looking at the file, the line in question is:

$o['name'] = end(explode('/', $o['url']));

Seems like WP’s new strict standards has an issue with the ‘/’ as a parameter?
That’s pretty strange…

Do you have debug mode on or off?

Hey @elliot,

I have debug mode on for developing 🙂

Hi there,

I might have a related issue. Upon activation of the latest Options add-on (with ACF v4.3.5 & WordPress v3.8.1) I get the same error:

Strict Standards: Only variables should be passed by reference in /Users/bramwillemse/Dropbox/Sites/gsc/wp-content/plugins/acf-options-page/acf-remote-update.php on line 27

Next to that I’m not able to register a page with this code in functions.php:

if( function_exists('acf_add_options_sub_page') )
{
    acf_add_options_sub_page(array(
        'title' => 'Contact',
        'parent' => 'options-general.php',
        'capability' => 'manage_options'
    ));
}

Also other options page functions do not have any effect. And this happens when trying to add a group to the options page:

Any help would be much appreciated!
