Description

Warning Raised
Invalid argument for foreach line 1350 of wp-includes/post.php

using
ubuntu14.04
Apache 2.4.6
MySQL 5.5
PHP Version 5.5.9-1ubuntu4.3 FPM

Writing a new theme, noticed this from go with only a functions.php (bare), index.php, header.php, footer.php and style.css (all pretty much empty apart from theme declaration get_header and get_footer)

Fixed by changing 

    foreach ( $args->taxonomies as $taxonomy ) {
      register_taxonomy_for_object_type( $taxonomy, $post_type );
    }

To

    if(is_array($args->taxonomies) || is_object($args->taxonomies) ){
      foreach ( $args->taxonomies as $taxonomy ) {
        register_taxonomy_for_object_type( $taxonomy, $post_type );
      }
    }

header.php

                'after'       => '</div>',
                'link_before' => '<span>',
                'link_after'  => '</span>',
            ) );
            edit_post_link( 'Edit', '<span class="edit-link">', '</span>' );
        ?>
      <?php endwhile; ?>
    <?php endif; ?>
<?php wp_footer(); ?> 
<?php get_footer(); ?>

functions.php is empty

style.css is empty

This is not my first Wordpress Theme, never encountered this before, I have fixed... Wish you had a github advertised on wordpress.org but if you do I cant find it...

What is the value of $args->taxonomies?

#2 @SergeyBiryukov

  • Component changed from Themes to Posts, Post Types
  • Keywords reporter-feedback added

This sounds like a plugin passing an invalid value to the taxonomies argument of register_post_type(), which only accepts an array​.

Does it still happen with all plugins disabled and a default theme (Twenty Fourteen or Twenty Thirteen) activated?

#3 @LewisCowles

while it does not happen with 2014 or 2013 activated, there are no plugins...

the value it is outputting when output in an else to the fix I posted is "post_tag"

By the way I have included all source code to the theme with this bug

;)
Oh and there are no plugins

I can't reproduce it on a clean install with the files you've provided. Is this a child theme?

#5 @LewisCowles

Hi Sergey,

No, not a child-theme, just a start at a new theme... I do not get the problem on wordpress 3.8, or 3.5 either, so I am also testing... Also as it has been pointed out that it should be receiving an array, so I have updated my proposed fix to the below...

    if( is_array($args->taxonomies) ){
        foreach ( $args->taxonomies as $taxonomy ) {
            register_taxonomy_for_object_type( $taxonomy, $post_type );
        }
    } else {
        trigger_error('Invalid input for taxonomies in register_post_type', E_USER_NOTICE);
    }

I Believe this would be a more suitable piece of code, although I concede that E_USER_NOTICE is my personal preference

I will try a fresh install...

  • Resolution set to invalid
  • Status changed from new to closed

no clue what I was doing, what eventually happened, no doubt it shipped without the bug, and was a theme issue :redface:
