Question

I am trying to make dynamic function where user can create list without adding <ul> <li> tag.

here is my function

function the_main_nav($navlinks){
        echo '<nav>';
        echo '<ul>';

        $menuitem = $navlinks;
        $pieces = explode(",",$menuitem);

        $i=$navlinks;
        while($i==','){ 
            echo '<li>' . $pieces[$i] . '</li>';
            $i++;
        }

        echo '</ul>';
        echo '</nav>';      
    }

This is my template tag the_main_nav('1,2,3,44 5');

But its going into endless loop with error. I want auto generate <li> after each ',' commma. Also if possible I want anchor link within the list so it can be linked with the page.

Answer 1

Instead of while loop, use foreach:

foreach ( $pieces as $piece ) {
  echo '<li>' . $piece . '</li>';
}
