# Inserting custom text into posts by category?

 * Is there a plugin that will allow you to insert custom HTML based in post category?
   I want to insert a block of text to groups of posts, say a “Tip” or a “Idea” 
   or “Warning.” But I don’t want to insert a shortcode in EACH post. I want to 
   write the custom text for each category and have WordPress add it automatically
   to all posts in that category.
 * I’ve searched for plugins but can’t find any that does this. 🙁

 * Oh, and since I already have custom post footer text (text that appears at the
   end of each post), I want this other custom text to appear elsewhere. Specifically,
   I want it to appear IN the post, like maybe after 1-2 paragraphs.

 * Hmm. Looks like I found something that works. Anybody want to comment? I don’t
   know what half of it means. I copied and modified the code from this page [http://www.wpbeginner.com/wp-tutorials/how-to-insert-ads-within-your-post-content-in-wordpress/](http://www.wpbeginner.com/wp-tutorials/how-to-insert-ads-within-your-post-content-in-wordpress/)
 * Seems to work for me initially.
 *     ```
       //Makes the next part work.
       function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
         $closing_p = '</p>';
       $paragraphs = explode( $closing_p, $content );
       foreach ($paragraphs as $index => $paragraph) {
   
        if ( trim( $paragraph ) ) {
        $paragraphs[$index] .= $closing_p;
       }
   
        if ( $paragraph_id == $index + 1 ) {
       $paragraphs[$index] .= $insertion;
       }
       }
             return implode( '', $paragraphs );
       }
   
       //Insert ads after second paragraph of single post content.
   
       add_filter( 'the_content', 'prefix_insert_post_custom' );
       function prefix_insert_post_custom( $content ) {
        $ad_code = '<div>Custom text here</div>';
       if ( in_category('0') && is_single() ){
       return prefix_insert_after_paragraph( $ad_code, 2, $content );
       }
       return $content;
       }
       ```
