Let's say my email is test@test.com, I am registered with Gravatar.com and I have defined a custom image.
Now, when I try and follow the instructions that appear on gravatar.com and do this:
$gravatar = md5( strtolower( trim( $user->email ) ) );
<img src="http://www.gravatar.com/avatar/<?= $gravatar ?>?s=100" />
I don't get the default gravatar image, so that means there's something wrong with the email address I entered.
But when I remove the strtolower and the trim functions, everything is working perfectly.
Note: $user->email = test@test.com (no trailing spaces or capitals anywhere).
Why is that? also, if I echo $gravatar with the strtolower and trim functions, it looks exactly the same.
Not sure what was the problem, it generates the same hash now. didn't before. Maybe I had a misspell somewhere, thanks anyways guys
