Import youtube vids, use JWplayer in theme only when metabox in admin is filled

Hi,

I purchased your plugin and i works great! Now i have a question and want to know if my idead is possible.

I use Flex Mag theme for my site, i import youtube videos with Video Blogster. What i’d like to do is as follow:

I want to show Youtube videos in a post in JW Player only when the video url field of your plugin in admin (where you create the post) is filled, otherwise the featured image must be show. I know this can be done with if/elseif.

In Video blogster i can import the video url in a custom field, i think that had to be ‘_jwppp-video-url-1’.

I want to use the shortcode to display the video in stead of the featured image, i can manage that in my theme, that’s no problem.

I see that you can use this shortcode [jw7-video p=”67026″] (video of post 67026 will be shown). What code i have to use in my template file to get the (youtube) video of a post?

Earlier i used Featured Video plugin, the code taht i used to show the video (only when it has a video) was something like this in the thme file:

<?php if ( ( has_post_video() ) ) { ?>
<?php echo (the_post_video()); ?>

and this coe in the function file was something like this:

<?php }
}

if ( has_post_video() ) {
the_post_video();
{ ?>

How can i create the function that tells wordpress to show the video when the metabox in admin is filled? And what will be the code for my theme file so i can only show the youtube video when the metabox in admin is filled?

so it has to be something like:

If …._jwppp-video-url-1

<?php echo do_shortcode([jw7-video p=”postid”]); ?>

elseif

If i know the function en theme code i think i can manage the rest myself. Hope you can help me in the right direction.

Thanks in advanced.
