mnybud Posted August 30, 2006 Share Posted August 30, 2006 I have this Wordpress plugin code (shown below) that pulls definitions from Google. I just call it in my wordpress posts as ~GetDEF(Your_Search_Term)~ and it works great as long as Google has a definition for the term inputed. If Google does not have a definition then it just prints ~GetDEF(Your_Search_Term)~ instead which is kind of ugly.I am wondering is there a way to make it so it displays nothing if the term is not found? I dont know much about PHP so if anyone can help please tell me what I should use to stop this and where I should put it in the code. If you need more info please let me know. Thanks in advance!!Here is the plugin code, its just one php file://Server Configuration$host = "www.google.com";$searchStr="http://www.google.com/search?ie=utf8&oe=utf8&q=define:";function getDEF( $def ) { global $host,$searchStr,$path; $fp = fopen ($searchStr.$def, "r"); if (!$fp) { exit; } $contents =""; $article=""; while (!feof ($fp)) { $contents .= fread($fp, 8192); } if (eregi ("<ul type=\"disc\">(.*)</ul>", $contents, $out)) { $article = $out[1]; }if (eregi ("<li>(.*)<li>", $contents, $out)) { $article = $out[1]; } $article=eregi_replace("<a(.*)[/url]","",$article); $article=strip_tags($article); fclose($fp);$article=trim($article);if($article!=""){$description= "</br><span class=\"gdescription\">This definition of ".$def.' is provided by the best search engine in the world, Google!</span>';$article = "<div class=\"Gdef\">".$def.":".$article.$description."</div>";}return $article;}function def_fy( $text ) { $text = preg_replace( "#\~GetDEF\((\S*)\)\~#imseU", "getDEF('$1')", $text );return $text;}function def_css() { echo " <style type='text/css'> div.Gdef { border: 1px dashed silver; background-color: #f0f0f0; padding:0 2em 0 2em; } .gdescription { font-size: 80%; padding:0 2em 0 2em; } </style> ";}add_action('wp_head', 'def_css');add_filter('the_content', 'def_fy', 2);add_filter('the_excerpt', 'def_fy', 2);?> Quote Link to comment Share on other sites More sharing options...
