    <p>i'm having a difficult time getting youtube video data via json and php. </p> <p>i've spent a full night and morning trying code snippets from around the web and stack overflow. </p> <p>the fact that they are not working suggests to me that i am not using up to date syntax. </p> <p>i think the clearest way to ask this question is to ask whether the following properties are correct as at november 2012. </p> <p>so this is my initial variable declaration:</p> <pre><code>$json = file_get_contents("http://gdata.youtube.com/feeds/api/videos/{$random_text}?v=2&amp;alt=json"); $json_data = json_decode($json); </code></pre> <p>can anyone please tell me if the following are correct:</p> <pre><code>1. $video_title = $json_data-&gt;{'entry'}-&gt;{'title'}; 2. $video_date = $json_data-&gt;{'entry'}-&gt;{'published'}; 3. $video_duration = $json_data-&gt;{'entry'}-&gt;{'media:group'}-&gt;{'yt$duration'}; 4. $video_views = $json_data-&gt;{'entry'}-&gt;{'yt$statistics'}-&gt;{'viewCount'}; 5. $video_description = $json_data-&gt;{'entry'}-&gt;{'content'}; </code></pre> <p>i don't want to dilute the question by providing too much other code and information, but one of the errors i am getting is:</p> <pre><code>Catchable fatal error: Object of class stdClass could not be converted to string </code></pre> <p>so i know one of those properties is not correct. </p> <p>thank you for your help, i'm gonna get a coffee and come back to this!</p> <p><strong>research</strong></p> <p>these resources are the direct api references to the properties i am trying to get and should work but they don't seem to be :(. </p> <p>the feed and entry structure:</p> <p><a href="https://developers.google.com/youtube/2.0/developers_guide_protocol_understanding_video_feeds#Understanding_Video_Entries" rel="nofollow">https://developers.google.com/youtube/2.0/developers_guide_protocol_understanding_video_feeds#Understanding_Video_Entries</a></p> <p>the contents of an entry:</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_entry" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_entry</a></p> <p>title tag:</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_title" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_title</a></p> <p>published tag:</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_published" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_published</a></p> <p>yt:duration tag:</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_yt:duration" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_yt:duration</a></p> <p>yt:statistics > viewCount tag:</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_yt:statistics" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_yt:statistics</a></p> <p>content tag (video description):</p> <p><a href="https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_content" rel="nofollow">https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_content</a></p> <p><strong>code sample</strong> (as requested)</p> <p>so what i am doing is:</p> <ul> <li>i have a form</li> <li>upon submit it is processed by a php file (insert.php)</li> <li>which makes some changes to the data and then submits to the database</li> <li>i get the error message at the line starting with $final_li_code (but the code there works if the json variables are not included, so the problem is with the json variables) </li> <li>(i have been told this form is vulnerable to sql injection but it is not a public facing form ie it is htaccess/htpasswd protected). </li> </ul> <p>this is the relevant code from insert.php:</p> <pre><code>// basic form information $field1 = $_POST["field1"];

    2. COGet rid of the curlies and single quotes. `$json_data->entry->title` Alternatively, pass a second argument of `true` to `json_decode` and access it as an array, `$json_data['entry']['title']`. The arrows and curlies look like something out of Perl, where it would be the syntax to access nested arrayrefs. In PHP, curlies and quotes like that do some funny stringification and generally should not be used without understanding the actual thing going on.

    3. COthanks for your reply, trying to test first solution, code editor does not like `$video_duration = $json_data->entry->media:group->yt$duration;` and `$video_views = $json_data->entry->yt$statistics->viewCount;` - can you please tell me what the syntax should be for these? thank you.

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.
