effigy Posted January 31, 2007 Share Posted January 31, 2007 Can you be more specific? Are you trying to remove all embed tags? Link to comment https://forums.phpfreaks.com/topic/36488-very-confuse-with-embed-codes/#findComment-173690 Share on other sites More sharing options...

effigy Posted January 31, 2007 Share Posted January 31, 2007 By "good" do you mean properly formatted (valid)? Users should be allowed to use object, param, and embed tags as long as they conform to HTML, basically, right?

effigy Posted January 31, 2007 Share Posted January 31, 2007 OK. Are those tags always required, and only those tags? Meaning, an object tag must contain two param tags, one for "movie" and one for "wmode." And it must also contain 1 embed tag? What about the attributes? Are those always required?

kucing Posted February 1, 2007 Author Share Posted February 1, 2007 Hi..Yes in normal case it would be, as many of my members started putting their fav movies from google video and youtube but I also have seen few putting their photo album using slide means there is no <object> or <param> but it only has <embed> tags is attributes you mean "value" or "<param name="allowScriptAccess" value="never">"..and effigy I will appreciate your help :)Thanks Link to comment https://forums.phpfreaks.com/topic/36488-very-confuse-with-embed-codes/#findComment-174170 Share on other sites More sharing options...
effigy Posted February 1, 2007 Share Posted February 1, 2007 Here's an example. Keep in mind that I am checking formatting, not validity. Also, it's only checking for double-quoted attributes:[code]<?php $tests = array( ### Good '<object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/dZ7h8q4kMBE_E"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/dZ7h8q4kMBE_E" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object>', ### Bad '<object width="425" height="350"><param name="movie" value="http://www.yo utube.com/v/aa$$33ffZZxx uot;></param>< ;param name="wmode" value="transparent&q uot;></param>< ;embed src="http://www.yout ube.com/v/aa$$33ffZZxxuo t; type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"> ;</embed></objec t>' ); foreach ($tests as $test) { // How many tags are there? $tags = preg_match_all('%<[^>]+>%', $test, $matches); $number_of_tags = count($matches[0]); // How many properly formatted tags are there? preg_match_all('%</?[a-z]+(?:\s+[a-z]+="[^"]+")*>%', $test, $matches); $number_of_tags_format_ok = count($matches[0]); // These should match. echo ($number_of_tags == $number_of_tags_format_ok) ? 'Tags are OK' : 'Tags are not OK'; echo '<br>'; } ?>[/code] Link to comment https://forums.phpfreaks.com/topic/36488-very-confuse-with-embed-codes/#findComment-174631 Share on other sites More sharing options...
