    <p>I've had a look at a lot of the similar questions and I'm not getting it, with regards to my code.</p> <p>The Error : <code> Strict Standards: Only variables should be passed by reference in wordpress/wp-includes/class-oembed.php on line 116 </code></p> <p>and here is my code....</p> <pre><code>// Get Ready Display the Audio $embedCheck = array("&lt;embed", "&lt;ifram");// only checking against the first 6 $mykey_values = get_post_custom_values('_format_audio_embed'); $content_oembed = ''; // check if the audio metabox is used if ( isset($mykey_values) &amp;&amp; !empty($mykey_values) ) { // iterate over values passed foreach ( $mykey_values as $key =&gt; $value ) { $url = $value; $wtf = wp_oembed_get($url); if ( !empty($url) ) { $firstCar = substr($url, 0, 6); // get the first 6 char. // if its a http(s). if ( strpos($firstCar, "http:/" ) !== false || strpos($firstCar, "https:" ) !== false ) { // send it to wp_oembed to see if the link is oembed enabled. $content_oembed = ($wtf !==false) ? ('"&lt;div class="audio" style="width:100%; overflow:hidden;"&gt;' .$wtf.'&lt;/div&gt;') : ('&lt;audio src="'.$url.'" preload="none" type="audio/mpeg"&gt;&lt;/audio&gt;'); } // if its the embed code that matches our array defined above. else if ( audio_strpos_arr($firstCar, $embedCheck ) !== false ) { $content_oembed = '&lt;div class="video" style="width:100%; overflow:hidden;"&gt;' .$url. '&lt;/div&gt;'; } } }; // end foreach } // end conditional </code></pre> <p>If I remove the section in the conditional below the comment "send it to wp_oembed to see if the link is oembed enabled.", but stranger still if I pass it a soundcloud link - no error, but if its a locally hosted file it goes tits up.</p> <p>Any Help would be greatly appreciated.</p> <p>after a bit of fidling - seems the problem is related to this function <a href="http://codex.wordpress.org/Function_Reference/wp_oembed_get" rel="nofollow">http://codex.wordpress.org/Function_Reference/wp_oembed_get</a></p> <p>and what thats referencing in the incldued class-oembed.php says the following on line 116</p> <pre><code>112 function discover( $url ) { 113 $providers = array(); 114 115 // Fetch URL content 116 if ( $html = wp_remote_retrieve_body( wp_safe_remote_get( $url ) ) ) { </code></pre>

    1. COWhen you show code and give us a line number please do us the favour of marking it in the code. Just a comment saying `// This is line 116` or something.

    2. COHey Swerri - sorry for the confusion - the line number is in a wordpress included file called class-oembed.php - but the error is being caused by something I'm doing here specifically around that function wp_oembed_get

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
