II.Create a customized WordPress Template

Prerequisite: chapter I.

Making a template is required if you need to embed PHP code into a WordPress page. There are other methods of course, but this is the proper way to do it.

As an example, let’s look at top part of this page. There’s this simple random characters generator which takes user’s input to define characters length as parameter to generate characters.


This file is our customized template file and is saved under /wp-content/themes/twentynineteen-child folder. WordPress will detect its presence and load as a template on Dashboard. See following screenshot:

 <?php $rchars_len = isset($_GET['rchars_len']) ? $_GET['rchars_len'] : 16; ?>
                 #rchars label,
                 #rchars button{
                     vertical-align: middle;
         <div class="entry">             <form id="rchars" class="entry-content" action="#rchars" method="get">                 <label>                     <span>Chars length:</span>                     <input name="rchars_len" type="text" value="<?php echo $rchars_len;?>" autocomplete="off">                 </label>                 <button type="submit">Submit</button>             </form>             <p class="entry-content">Random chars: <?php echo substr(md5(rand()), 0, $rchars_len); ?></p>         </div>
 <!-- end of specific content from random chars template-->
     get_template_part( 'template-parts/content/content', 'page' );     // If comments are open or we have at least one comment, load up the comment template.     if(comments_open() || get_comments_number()){         comments_template();     } endwhile;//end while
     </main><!-- #main --> </section><!-- #primary -->
