  I am having trouble with adding PHP code to my WordPress weather directly into header.php or using functions.php. All my tests suggest it should produce a valid meta string. Either way if crashes the entire site. It is to add a meta tag for keywords using topics. I get a valid string The code is as follows using functions.php:

  function get_my_meta_keywords()
  {
  // Make sure post
  if(is_singular( ‘post’ ) == TRUE)
  {
  $ID = get_the_ID();
  // Make sure we have and ID
  if($ID != FALSE)
  {
  $meta_catagory = get_the_category($ID);
  $asize = count($meta_catagory);
  // Make sure we have at least one category
  if($asize > 0)
  {
  $category_string = “”;
  // Loop through category array
  for($i = 0; $i < $asize; $i++)
  {
  // Add to the category string
  $category_string = $category_string.$meta_catagory[$i]->name;
  // Add a comma if another category is in array
  if($i != $asize – 1)
  {
  $category_string = $category_string.’,’;
  }
  }
  // Echo the meta tag
  echo ‘<meta name=”keywords” content=”‘.$category_string;.'”>’;
  }
  }
  }
  }

  add_action( ‘wp_head’, ‘get_my_meta_keywords’);

  I have tried to add this directly in header.php in the meta tag area as simple PHP as follows:
  <?php
  // Make sure post
  if(is_singular( ‘post’ ) == TRUE)
  {
  $ID = get_the_ID();
  // Make sure we have and ID
  if($ID != FALSE)
  {
  $meta_catagory = get_the_category($ID);
  $asize = count($meta_catagory);
  // Make sure we have at least one category
  if($asize > 0)
  {
  $category_string = “”;
  // Loop through category array
  for($i = 0; $i < $asize; $i++)
  {
  // Add to the category string
  $category_string = $category_string.$meta_catagory[$i]->name;
  // Add a comma if another category is in array
  if($i != $asize – 1)
  {
  $category_string = $category_string.’,’;
  }
  }
  // Echo the meta tag
  echo ‘<meta name=”keywords” content=”‘.$category_string;.'”>’;
  }
  }
  }
  ?>
