Post format metabox shows duplicate 'standard' format

[ptahdunbar]

Having 'standard' within add_theme_support makes the standard option show up twice within the post format metabox on the write/edit screen.

add_theme_support( 'post-formats', array( 'standard', 'aside', 'chat', 'gallery', 'link', 'image', 'quote', 'status', 'video', 'audio' ) );

Patch fixes this by skiping over standard since it's hardcoded in the metabox.

This should probably happen in add_theme_support() directly.

Hacky way to do this.

[nacin]

Probably just wontfix, or at least low priority into the future. Simple way to avoid this is removing support for 'standard'. All themes support 'standard' by default.

fixing it in theme.php

Added a pretty simple fix for this in the add_theme_support function, removing it from the input array with array_splice.

16555.3.diff​ corrects the whitelist, rather than the user input.

nice one.

In 30038:

Don't display Standard post format twice in the meta box if the theme unnecessarily mentions it in the add_theme_support() call.
