    <p>Execute the script via the console, not the web server.</p> <p>The cron could look like this:</p> <pre><code>*/5 * * * * php -f /path/to/cron.php </code></pre> <p>Then the file could do this:</p> <pre><code>cron.php: &lt;?php if ( array_key_exists('REMOTE_ADDR', $_SERVER) ) die("Can only be run from the command line!"); </code></pre> <p>That will guarantee it's only run by the server.</p> <p><strong>Edit in response to comments</strong></p> <p>You can't get to a public folder inside a private folder, in general, and if you can't add new directories outside the web root, your cache dir will have to be protected another way.</p> <p>I'm going to assume all your files are in the web root, ie: <code>/home/site/publichtml</code>. Replace that with whatever your directory is.</p> <p>Create a new directory <code>/home/site/publichtml/.cache</code>. Add the following as a .htaccess file:</p> <pre><code>Deny from all </code></pre> <p>Now your scripts should be able to access the folder from the file system, but it's inaccessible via the web server.</p> <p>If you can set up a cron job on the server (via the web admin or another way, it sounds like you can) do it as above, ie: Use <code>php -f /home/site/publichtml/cron.php</code> as the command, and include the check for the array key.</p> <p>Alternatively, you can check like this:</p> <pre><code>if ( !isset($_SERVER['argc']) ) die("Must be run from the command line!\n"); </code></pre> <p><code>$_SERVER['argc']</code> is only set when the script is executed from the command line.</p> <p>If you can keep the cron script out of the web root, good. If not, that should be secure.</p> <p>Finally, to get rid of the E_NOTICES, add this to the top of the cron.php:</p> <pre><code>error_reporting(E_ALL ^ E_NOTICE); // Turn off notices </code></pre> <p>or</p> <pre><code>error_reporting(0); // Hide all error reporting </code></pre>

    1. COI don't have access to the console unfortunately. It's a shared webhost.

    2. COIf you can set up cron jobs (via an admin panel) you should still be able to make this work, but you might lose some of the security (eg: need to move the cache dir into the web root).

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.

SQuiL has stopped working due to an internal error.

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