Can you give more information rather than just giving code and saying it shows all the time.

Sounds though like your URL looks something like this when getting to this page somepage.php?image_id=something&cat=something&id=something

You should probably read some PHP tutorials because I don't think the code you wrote is going to do what you want it to do (because it will display 3 messages no matter what your URL says).. based on what I could decipher from your excellent grammar skillz... ;P

I think I understand your question, do you mean

if(isset($_GET['images_id'])) {

echo'picture';

}

else if(isset($_GET['cat'])) {

echo'choused category';

}

else if (isset($_GET['id']))  {

echo'all category\'s';

}
else {

echo'error';

}

oh.. :/ i need if cat exist in databaze then will show the page, if dosn't then page are showing error..

exemple..

index.php?id=images&cat=1 - i have cat whit id 1, then page show next options..
but if
index.php?id=images&cat=2 - and i don't have it, then will show error..
and whit images id thesame index.php?id=images&cat=1&images_id=1 - exist, then showing, index.php?id=images&cat=1&images_id=2 dosn't then showing error..
happy new year! 😉

isset function will only tell you if the variable has a value.

if cat=1 or cat=2 isset is true.. just use

if ($_REQUEST['cat'] == '1')
//echo
else
//echo error

But if cat=2 doesn't exists, your database will have to tell you that. You don't know if it exists just from the URL
