对于具有最大文本字段的循环

Question

I want to print a text field 6 times, however if all of them are filled then the loop should not continue. Here's my code:

 <fieldset class="keywords">
  <?php
    $fkeywords = get_the_terms($pid, 'fkeywords');
    if (is_array($fkeywords)) {
      foreach ($fkeywords as $keyword) {
       echo '<input type="text" name="fkeywords[]" id="'.$keyword->slug.'" value="'.$keyword->slug.'">';
      }
    }
  ?>
 <ol>
<?php for ($i=0; $i<6; $i++ ){ ?>
    <li><input type="text" size="20" name="foodir_keywords[]" /></li>
<?php } ?>
 </ol>

</fieldset>

Answer 1

I somehow figured it out myself:

$keyCount = count($fkeywords);
for ($i=0; $i<6-$keyCount; $i++)
