      Hi,

      I’m trying to replace the default quotes in WordPress (” “) with their german equivalents („ “). Adding a filter to the_content and doing a str_replace works fine for normal post and page content but of course not for custom fields.

      I found a solution using output buffering to do a string replace on everything before a page is sent to to browser. Again it works fine everywhere but my Piklist fields. 

      ob_start();

add_action('shutdown', function() {
    
    $final = '';

    $levels = ob_get_level();

    for ($i = 0; $i < $levels; $i++)
    {
        $final .= ob_get_clean();
    }

    // Apply any filters to the final output
    echo apply_filters('final_output', $final);

}, 0);

add_filter('final_output', function($text) {

  $text = str_replace( '“' , '„' , $text );
  $text = str_replace( '”' , '“' , $text );
  $text = str_replace( '‘' , '‚' , $text );
  $text = str_replace( '’' , '‘' , $text );
  return $text;

});

      I’ve already tried different hooks to no avail. Can you think of another simple solution that would work with Piklist’s custom field content without having to deal with it on a field by field basis?

      Thank you
      Stefan

      It looks like the output buffering solution does work with normal text (“Bar” replaces “Foo”) even for Piklist fields. Only the html entities, that I have to use for my quotes problem, are being ignored.

      @bubdev– I’m not 100% sure I understand the issue, but I may have another solution.

      Try using a language file to change the quotes. If you create a MO file with the translation it should work everywhere. As is probably easier to implement.

      Thank you, Steve, and sorry for not making quite clear, what I’m trying to achieve. I don’t want to replace any quotation marks within my files, so the translation file won’t help. I’m aiming at the text the user types into the text editor.

      In the code I posted above the Unicode entities for the quote marks have been translated to symbols on saving the post. The str_replace part should actually look as follows (without the spaces after the ampersands):

      `add_filter( ‘final_output’, function( $text ) {

      $text = str_replace( ‘& #8220;’ , ‘& #8222;’ , $text );
      $text = str_replace( ‘& #8221;’ , ‘& #8220;’ , $text );
      $text = str_replace( ‘& #8216;’ , ‘& #8218;’ , $text );
      $text = str_replace( ‘& #8217;’ , ‘& #8216;’ , $text );
      return $text;

      });`

      The filter works fine everywhere on my site and replaces the quotation marks – except for the content of my Piklist text editor fields. They do accept a str_replace of normal text, only the Unicode entities are being ignored.

      @bubdev– Can you email your plugin to [email protected] ? It will be easier for us to debug if we can see the full code.
