[RESOLVED] Undefined index Error

[Shawazi]

Okay so undefined variable was a matter of utilizing isset, but this undefined index I have no idea what to use.

Notice: Undefined index: user_id

where I have something like :

$result = my_query("SELECT columns FROM table WHERE id='".$row['user_id']."'");

It's telling you that currently there is no element in array $row with an index of 'user_id', so you need to make sure that (1) you've used the correct array name and index name (which is case-sensitive should that be the issue), and (2) that there is not some error in your logic which is assuming that such an array element should exist at this point. (You might want to try doing a print_r($row) to see what is actually there.)

I thought I had it being selected but I didn't. What a beginner mistake. :glare:
