JWPlayer has become my favorite video player for clients website especially after they release their official WordPress plugin. The plugin almost done all the basic things ( shortcode, custom player, etc ). It’s also integrated seamlessly with the WordPress Media library which makes your life so much easier because you can easily add the player to a post straightly from media library. However, aside from all that simple integration and setup, it lacks of documentation could cause a headache especially if you are trying to do something out of the lane.

Today, I was trying to use JWPlayer plugin to show video in a custom post type template which grab the video file from external URL ( not from Media Library ). I was thinking this would be an easy task because I could easily execute the shortcode using do_shortcode() function in WordPress. But, apparently JWPlayer plugin handle the shortcode quite different from another plugin so you have to use jwplayer_tag_callback() function instead of do_shortcode(). I don’t know the reason why they make it like that but as long as it works then it’s fine. Here is the sample code to make it clear:

//won't work
do_shortcode("[jwplayer link='http://xxx.com/xxx.mp4']");
 
//obviously will work
jwplayer_tag_callback("[jwplayer link='http://xxx.com/xxx.mp4']");

Actually you can find this solution easily in Google. However, I’ll put it in my blog just because I am lazy to find it again.

So wordpress has default email address and name which are “WordPress” as the name, wordpress@yourdomain.com as the email. To change it you can use plugin or put these wordpress action to your functions.php file in themes folder :

add_filter('wp_mail_from', 'new_mail_from');
add_filter('wp_mail_from_name', 'new_mail_from_name');
 
function new_mail_from($old) {
 return 'no-reply@rudylee.com';
}
 
function new_mail_from_name($old) {
 return 'Rudy';
}

Just change the email address and name to your’s. Hope it works, cheers.
