    <p>I set up a cron job to run the following script every 30 min, Basically this script selects article info from <strong>stories</strong> table where field <strong>showing=0</strong> And it than counts votes related to that article, the votes are located in <strong>votes</strong> table. <strong>itemname_field</strong> in votes table is equal to <strong>id</strong> field in stories table. If you need more information on database structure and voting system, I describe it in depth here: <br /> <a href="https://stackoverflow.com/questions/8609678/set-a-cron-job-to-update-article-information-depending-on-its-vote-values">Set a cron job to update article information depending on its vote values</a></p> <pre><code>&lt;?php mysql_connect("localhost","username","password") or die (mysql_error("There was an error in connection")); mysql_select_db("database") or die (mysql_error("There was an error in connection")); $query = "select sum(vt.vote_value) as vote_value, vt.item_name from Votes vt join stories st on st.id = vt.item_name and st.showing = 0 group by vt.item_name"; $result = mysql_query($query); while($row = mysql_fetch_array($result)) { if($row['vote_value'] &gt; 9) { $showing = 1; } else if($row['vote_value'] &lt; -9) { $showing = 2; } else { $showing = 0; } $query2 = "UPDATE `stories` SET `showing` = $showing WHERE `id` = '".$row['item_name']."'"; mysql_query($query2); } ?&gt; </code></pre> <hr> <p>Can anyone suggest the reason, why this script is not working? If everything is alright with script, could it be something in cron job that needs to be done?</p> <p><strong>EDIT:</strong> when I run script in browser it gives the following error:</p> <pre><code>Warning: mysql_fetch_array(): supplied argument is not a valid MySQL </code></pre> <p>Which is this line <code>while($row = mysql_fetch_array($result))</code></p>

    2. COIt's not doing the job, I've set several articles to showing=0 and added vote values to them that are grater or smaller than (9, -9). But after cron job runs nothing changes.

    3. COCheck your syslog to make sure the script is actually ran. Also check your php error log.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
