<p>I'm trying to configure the SimplePie RSS parser to cache feeds into a mySQL database, but I keep getting this error messages when I try to load a SimplePie page:</p> <ul> <li>Fatal error: Call to a member function set_cache_location() on a non-object</li> <li>Warning: substr() expects parameter 1 to be string, array given in</li> <li>Warning: PDO::__construct() expects parameter 2 to be string, array given </li> </ul> <p><strong>When I set "port" as "port" I get the following error message:</strong></p> <blockquote> <p>Warning: mysql:// "IT DISPLAYS MY DB USERNAME AND PASSWORD HERE" is not writeable. Make sure you've set the correct relative or absolute path, and that the location is server-writable. in /home/...../SimplePie.php on line 1357</p> </blockquote> <p>Is there anyone familar with SimplePie?</p> <p><strong>EDIT</strong></p> <p>In the code below I've obviously left out my username and password for the mySQL settings.

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.
