php - Detect if a youtube channel exists anymore & don't display if it gives Error? -


so, after making new youtube page, noticed of current users have linked youtube channels via youtube api , our database, of users channels give error, no longer exist.

https://gyazo.com/d2ca429e408c9d843ee6e848ac8c4dda

so creating subscribe buttons code in echo in function.

<div class="g-ytsubscribe" data-channelid="'.$youtube_info['channel_id'].'" data-layout="full" data-count="default" data-onytevent="onytevent"></div>

so can see, fetch data database , contacts youtube fetch channel info. of users channels no longer exist, wondered if there way detect this? , not display particular user being displayed @ all?

so query function.

    $query = "select user_id, yt_channeltitle, channel_id points channel_id !='' , yt_channeltitle != '' "; $query .="order channel_id desc limit " . ($objectsperpage*2) . " offset " . $_session['last_record'];

i mean maybe thinking accross lines of type of maybe str_replace? method perhaps? question of detecting word error because gets displayed in youtube button instead of channel subscriber count , profile image, shows red icon error.?? open ideas :)

thanks

i wanted post answer question, , sorted workaround out issue.

i created section in our admin section can edit channel_id easily, , made blank. :)

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
