Querying info from one table based on info in another


Posted on 16th Feb 2014 07:03 pm by admin

Hi, I am currently trying to make a part for my user driven website where one user can subscribe to another and whoever they have subscribed to is echoed back on there profile page.

my users table structure is: id username password and my subscription table is: id user_id follow_id

Did you know?Explore Trending and Topic pages for more stories like this.
i am currently trying to query the logged in users subscriptions with this sql_query

$subsQuery = mysql_query("SELECT U.username FROM users AS U INNER JOIN subscription AS Sub.follow_id=U.id WHERE Sub.user_id=".$ID); $ID being the logged in users id.

However when trying to echo this on the page using this bit of php:

<? while ($subs = mysql_fetch_assoc($subsQuery)) { ?><br /><br />
<? echo $subs['username'] ?>

<? } ?>

it throws back this error:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/avince/public_html/users/user.php on line 53

Any help would be much appreciated!
