Question

for some reason i can not understand im having troubles with mysql_num_rows.

Heres the script:

$notquery = 'SELECT * FROM notification WHERE uid = 1 AND read = 0 
AND tipo = post 
OR tipo = subpost OR tipo = logros';

$notQuery = (mysql_query($notquery));

$num_rows = mysql_num_rows($notQuery);

error:

Warning:  mysql_num_rows(): supplied argument is not a valid MySQL result resource

Answer 1

The sql is full with syntax error, try this

SELECT * FROM notification 
WHERE 
uid = 1 AND 
`read` = 0 AND 
tipo in('post', 'subpost', 'logros');
