Fixing the wp_editor Error in WordPress 3.9

April 23, 2014

Apparently, a lot of us have been using wp_editor incorrectly and didn’t even know it. As of the WordPress version 3.9, you will receive an error if you are still using it this way:

	/**
	* This is how NOT to do it
	**/
	// Codex usage:
	wp_editor( $content, $editor_id, $settings = array() );

	// Example of inproper use (in a widget)
	wp_editor( ‘content’, $this->get_field_id( ‘content’ ) );

	// Example of inproper use elsewhere
	// Change settings_field_name[content] to the correct settings field and field name
	wp_editor( ‘content’, ‘settings_field_name[content]’ ) );

The actual method is to place your field id in the textarea_name argument in the settings paramenter, like this:

	/**
	* This is the correct method of using wp_editor()
	**/
	// Codex usage:
	wp_editor( $content, $editor_id, $settings = array() );

	// Example of proper use in a widget
	wp_editor( ‘content’, ‘content’, array( ‘textarea_name’ => $this->get_field_id( ‘content’ ), ) );

	// Alternate method when get_field_id is not available (options page or other)
	// Change settings_field_name[content] to the correct settings field and field name
	wp_editor( ‘content’, ‘content’, array( ‘textarea_name’ => ‘settings_field_name[content]’ ), ) );

It’s an easy fix, one that I’ve already seen a few plugins make since WordPress 3.9 was released. See the codex for more information on using wp_editor().

Update February 26, 2015: The code above originally showed the error using the Widget API get_field_id(), I’ve updated this to show how it might be used in/correctly elsewhere in WordPress.

Bao,

I would suggest you reach out to the WordPress Support forums. I don’t think you’re getting the same error that I am talking about in this post. I’d have to see the warning itself to know.

Also, please post your code in a gist, linked into your comment.

Best of luck,
Joshua
