Better, Stronger, Faster youtubebadge
Last modified: March 26, 2008 - 19:34
I removed the requirement to include the Zend library separately. I added it to the module directory. This is what I ended up with. Considering adding this as a module.. but still dont like the included Zend library files.
<?php
ini_set('include_path', ini_get('include_path').':'.drupal_get_path("module", "youtubebadge"));
/**
* Zend gdata libraries had to be added to the php page. I did this inside settings.php
* by adding ' ini_set('include_path', ini_get('include_path').':path-to-zend-libraries'); '
* Got help from <a href="http://code.google.com/apis/youtube/developers_guide_php.html#YouTubeService
" title="http://code.google.com/apis/youtube/developers_guide_php.html#YouTubeService
" rel="nofollow">http://code.google.com/apis/youtube/developers_guide_php.html#YouTubeSer...</a> * Also, if you get a blank page, check the http error log, you might not be able to find DomDocument
* class if PHP was not complied with Dom support, installing the php-xml rpm fixed that issue. You
* could also recompile PHP without the --deisable-dom switch.
