Hi Josh! Thanks for responding. I followed a tutorial on this and this is the code I'm using
function my_mce_before_init_insert_formats( $init_array ) {
// Define the style_formats array
$style_formats = array(
// Each array child is a format with it's own settings
array(
'title' => 'Content Block',
'block' => 'span',
'classes' => 'content-block',
'wrapper' => true,
),
array(
'title' => 'Blue Button',
'block' => 'span',
'classes' => 'blue-button',
'wrapper' => true,
),
array(
'title' => 'Red Button',
'block' => 'span',
'classes' => 'red-button',
'wrapper' => true,
),
);
// Insert the array, JSON ENCODED, into 'style_formats'
$init_array['style_formats_merge'] = true;
$init_array['style_formats'] = json_encode( $style_formats );
return $init_array;
}
// Attach callback to 'tiny_mce_before_init'
add_filter( 'tiny_mce_before_init', 'my_mce_before_init_insert_formats' );Following this tutorial here: http://www.wpbeginner.com/wp-tutorials/how-to-add-custom-styles-to-wordpress-visual-editor/
Things to note:
I've moved the merge code to different locations to see if that made a difference. I tried it after the $init_array['style_formats'] = json_encode( $style_formats ); line as well as before $style_formats = array(
