How to add menu in WordPress admin panel – In this post we see how we can add custom menu to admin sidebar. Sometimes when we on WordPress and we need to show some features or any information in admin page then we can use this code snippet to create the same.

Example: Sometime we need to show content on frontend with adding some prefix or suffix or may be you have enter spelling mistakes in 2000 posts. so it is very difficult to modify 2000 posts so we can modify using filter . SO mistake will be replaced by correction.   For Modifying post content only:   function link_words( $text ) { $replace = ‘Replace with’; $text = str_replace( ‘Want To replace text’, $replace, $text ); return $text; } add_filter( ‘the_content’, ‘link_words’ );   For Modifying post excerpt only   function link_words( $text ) { $replace = ‘Replace with’; $text = str_replace( ‘Want To replace text’, $replace, $text ); return $text; } add_filter( ‘the_excerpt’, ‘link_words’ );   For Modifying post content and excerpt both   function link_words( $text ) { $replace = ‘Replace with’; $text = str_replace( ‘Want To replace text’, $replace, $text ); return $text; } add_filter( ‘the_content’, ‘link_words’ );
