I've got one mysql table with usernames, passwords and property names, that allows a user to log-in to a secure site section. Now what I'd like to be able to do is pull-in pdfs from a second table where it checks the property name from table one against the documentCategory of the pdfs in table two, and then only displays the relevant pdfs depending on the logged-in user. (Hope this makes sense)
Table structure:
Table 1 -
userid password property
Table 2 -
pdfFile documentCategory
Where table1.property = table2.documentCategory
Any help on how I can get this working in php would be greatly appreciated as I'm now completely lost.

If the user is already logged in (that is, you have the userid
) your SQL query would probably look like this:
$query = 'SELECT pdfFile
FROM table2
INNER JOIN table1 ON property = documentCategory
WHERE table1.userid = '.intval($userid);
$result = mysql_query($query);
Adapt this for your preferred database abstraction layer.
SELECT table2.pdfFile, table2.documentCategory FROM table2, table1 WHERE table1.property = table2.documentCategory AND table1.user_id = ?
Make sure table1.user_id has a PRIMARY index and table2.documentCategory has an index too.
select t2.pdfFile
from t1 inner join t2
on t1.property = t2.documentCategory
where t1.userId = $userId
Update... Not sure this is a php question... More like a SQL question.
