[Phpwebsite-developers] Proposal: Let modules place metatags

[Eloi G. <el...@re...>]

I've figured out a way to let modules change Layout's metatags on a "per 
page view" basis.  I'd like to hear what you guys think.  I didn't have 
it manage the title tag because there's already a 
$GLOBALS['Layout_title'] to handle that, but for code conformity it can 
be easily modified to handle that as well.

USAGE: Just assign desired tag contents to the appropriate array 
element.  It'll clean up after itself.
EXAMPLE:  $_SESSION['OBJ_layout']->meta_vars['meta_description'] = 'This 
is the best CMS in the world!';

In /mod/layout/class/layout.php add the following at line 211:

  /**
   * Content array for "one time only" meta tags specified by modules
   *
   * @var string
   * @access private
   */
  var $meta_vars;

then replace function getMetaTags with this one:

  function getMetaTags(){
    $metatags = "<meta name=\"generator\" content=\"phpWebSite\" />\n";

    if (isset($this->meta_vars['meta_keywords']))
      $metatags .= "<meta name=\"keywords\" 
content=\"".$this->meta_vars['meta_keywords']."\" />\n";
    elseif ($this->meta_keywords)
      $metatags .= "<meta name=\"keywords\" 
content=\"".$this->meta_keywords."\" />\n";

    if (isset($this->meta_vars['meta_description']))
      $metatags .= "<meta name=\"description\" 
content=\"".$this->meta_vars['meta_description']."\" />\n";
    elseif ($this->meta_description)
      $metatags .= "<meta name=\"description\" 
content=\"".$this->meta_description."\" />\n";

    if ($this->meta_robots){
      switch ($this->meta_robots){
      case "00":
    $metatags .= "<meta name=\"robots\" content=\"noindex, nofollow\" />\n";
    break;

      case "01":
    $metatags .= "<meta name=\"robots\" content=\"noindex, follow\" />\n";
    break;

      case "10":
    $metatags .= "<meta name=\"robots\" content=\"index, nofollow\" />\n";
    break;

      case "11":
    $metatags .= "<meta name=\"robots\" content=\"index, follow\" />\n";
    break;
      }
    }

    if (isset($this->meta_vars['meta_author']))
      $metatags .= "<meta name=\"author\" 
content=\"".$this->meta_vars['meta_author']."\" />\n";
    elseif ($this->meta_author)
      $metatags .= "<meta name=\"author\" 
content=\"".$this->meta_author."\" />\n";

    if (isset($this->meta_vars['meta_owner']))
      $metatags .= "<meta name=\"owner\" 
content=\"".$this->meta_vars['meta_owner']."\" />\n";
    elseif ($this->meta_owner)
      $metatags .= "<meta name=\"owner\" 
content=\"".$this->meta_owner."\" />\n";

    if (isset($this->meta_vars['meta_content']))
      $metatags .= "<meta http-equiv=\"content-type\" 
content=\"text/html; charset=" . $this->meta_vars['meta_content']."\" />\n";
    elseif ($this->meta_content)
      $metatags .= "<meta http-equiv=\"content-type\" 
content=\"text/html; charset=" . $this->meta_content."\" />\n";

    /* Erase the temporary tags */
    $this->meta_vars = array();
    return $metatags;
  }
