How to use/enable Pagination?

2 comments

1. I realise that you say that you can’t enable paging of users, but if it’s a case of you don’t know how, you can pass ‘number’ and ‘offset’ in the args array.

   In your example to get page 2 of your users, set ‘number’ as ‘5’ and ‘offset’ as ‘5’.

   If using those variables is not suitable you can always use a for loop with a count (instead of foreach) and insert a break every 5 iterations eg.

   for ($i = 0; $i < count($students); $i++) {
       // some code here
       if ($i % 5 == 0 && $i != 0 && $i != count($students)) {
           // insert page break code here
       }
   }
   

2. I don’t use pages in WordPress posts or pages too often, so I first did a test with this hand written markup. I used 26 users to purposefully get a last page with less than 5 students on it. Just to be certain.

   <ul>
       <li>A</li>
       <li>B</li>
       <li>C</li>
       <li>D</li>
       <li>E</li>
   </ul>
   
   <!--nextpage-->
   
   <ul>
       <li>F</li>
       <li>G</li>
       <li>H</li>
       <li>I</li>
       <li>J</li>
   </ul>
   
   <!--nextpage-->
   
   <ul>
       <li>K</li>
       <li>L</li>
       <li>M</li>
       <li>N</li>
       <li>O</li>
   </ul>
   
   <!--nextpage-->
   
   <ul>
       <li>P</li>
       <li>Q</li>
       <li>R</li>
       <li>S</li>
       <li>T</li>
   </ul>
   
   <!--nextpage-->
   
   <ul>
       <li>U</li>
       <li>V</li>
       <li>W</li>
       <li>X</li>
       <li>Y</li>
   </ul>
   
   <!--nextpage-->
   
   <ul>
       <li>Z</li>
   </ul>
   

   WordPress produces 6 pages with links in both the Page and the Post editor. You didn’t specify which you were using.

   To produce this markup with PHP, I created list of dummy students (A-Z) with this code since I could not produce your list.

   // Change this to change the number of students per page.
   $students_per_page = 5;
   
   // Set up a dummy user list. (26)
   $students = str_split( 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' );
   
   // Break the whole list in page sized chunks.
   $student_chunks = array_chunk( $students, $students_per_page );
   
   // Cycle through each page.
   foreach ( $student_chunks as $student_chunk )
       $pages[] = wpse_98352_get_student_page( $student_chunk );
   
   // Add page breaks and echo post or page.
   echo join( "n<!--nextpage-->n", $pages );
   
   /**
    * This code should be replaced with the actual code for each students
    * page.
    *
    * @param array $students A page worth of students.
    * @return string. Text of for this page.
    */
   function wpse_98352_get_student_page( $students ) {
   
       $return .= '<ul>';
   
       foreach ( $students as $student )
           $return .= "<li>$student</li>";
   
       $return .= '</ul>';
   
       return $return;
   }
   

   I got this:

   <ul><li>A</li><li>B</li><li>C</li><li>D</li><li>E</li></ul>
   <!--nextpage-->
   <ul><li>F</li><li>G</li><li>H</li><li>I</li><li>J</li></ul>
   <!--nextpage-->
   <ul><li>K</li><li>L</li><li>M</li><li>N</li><li>O</li></ul>
   <!--nextpage-->
   <ul><li>P</li><li>Q</li><li>R</li><li>S</li><li>T</li></ul>
   <!--nextpage-->
   <ul><li>U</li><li>V</li><li>W</li><li>X</li><li>Y</li></ul>
   <!--nextpage-->
   <ul><li>Z</li></ul>
   

   Which I pasted into a page to test.

   Then I adjusted the $students_per_page variable to 6, which got me this:

   <ul><li>A</li><li>B</li><li>C</li><li>D</li><li>E</li><li>F</li></ul>
   <!--nextpage-->
   <ul><li>G</li><li>H</li><li>I</li><li>J</li><li>K</li><li>L</li></ul>
   <!--nextpage-->
   <ul><li>M</li><li>N</li><li>O</li><li>P</li><li>Q</li><li>R</li></ul>
   <!--nextpage-->
   <ul><li>S</li><li>T</li><li>U</li><li>V</li><li>W</li><li>X</li></ul>
   <!--nextpage-->
   <ul><li>Y</li><li>Z</li></ul>
   

   So, it looks like the algorithm works on different students per page, even when the final page is less than a full page.

   NOTE: You will need to change the wpse_98352_get_student_page() function to produce your page data. I just used this markup to make testing possible. You will also have to stuff all this into the shortcode function.
