[Plugin: More Types] Wrong datatype?

Yep, same issue.

Appears on all the settings pages for a specific type.

Same here>
Wordpress 3.1 upgrade and Multisite enabled. It happens when I open up the “More types” from settings in sidebar.
“Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/hs0cgfpq/public_html/wp-content/plugins/more-types/more-types-settings.php on line 291”

Any Ideas?

Try This:
Paste the following code after line 182 in more-types-object.php:
$options[‘show_in_menu’] = true;
$options[‘capability_type’] = ‘post’;

Although not a perfect fix, I did manage to get rid of the error by editing more-type-settings.php from line 285 – 296 to this:

$tax = array();
        $stax = array();
        $mytax = $more_types_settings->get_val('taxonomies');
        foreach($wp_taxonomies as $taxonomy) {
            if (!trim($taxonomy->label)) continue;
            $tax[$taxonomy->name] = $taxonomy->label;
            if(is_array($mytax)) {
            if (in_array($taxonomy->name, $mytax)) $stax[] = $taxonomy;
            } else {
                $stax[] = NULL;
            }
        }

This is =not= a perfect fix, but it did got rid of the error. I’m not 100% sure how your custom taxonomies will respond to this!

This worked for me. And by worked, I mean the errors are not showing up and the plug-in continues to work. Right above more-types-settings.php >> 291…

if(!isset($mytax)) {
   $mytax = array();
} else if(!is_array($mytax)) {
   settype($mytax, "array");
}

This should not interfere with the plug-in (I think) as we are simply forcing $mytax into an array-type. If $mytax already exists as an array, nothing will change. The original in_array() test on 291 will have the proper conditions needed to complete it’s task.

Working for me here. Will report errors if encountered.

@trevornet’s fix also worked for me (WP 3.1.1 with two sites networked).

Just to be clear, lines 285-292 originally look like this:

$tax = array();
$stax = array();
$mytax = $more_types_settings->get_val(‘taxonomies’);
foreach($wp_taxonomies as $taxonomy) {
if (!trim($taxonomy->label)) continue;
$tax[$taxonomy->name] = $taxonomy->label;
if (in_array($taxonomy->name, $mytax)) $stax[] = $taxonomy;
}

You add in @trevornet’s code to line 291, pushing what’s on 291 down. So the above block of code now looks like this:

$tax = array();
$stax = array();
$mytax = $more_types_settings->get_val(‘taxonomies’);
foreach($wp_taxonomies as $taxonomy) {
if (!trim($taxonomy->label)) continue;
$tax[$taxonomy->name] = $taxonomy->label;
if(!isset($mytax)) {
$mytax = array();
} else if(!is_array($mytax)) {
settype($mytax, “array”);
}
if (in_array($taxonomy->name, $mytax)) $stax[] = $taxonomy;
}
