I need help in a test page i am doing in php

Hey i am not completely new to php but i need a bit of help.
I am trying to do a testing.php page.
i want the page to handle errors for empty input boxes.
Now i want it to do testing.php?error=1 then display the error message.
I have tryed a few codes that did not work but maybe should.

the first code i tryed was with switch statement like this.

switch($error) {
case 1:
echo "Error Number 1";
break;
case 2:
echo "Error Number 2";
break;
}

now that code didnt work.
so i tryed a simple if statement like this.

if ($error == "1") {
echo "Error Number 1";
}
if ($error) == "2") {
echo "Error Number 2";
}

again didnt work when i type in testing.php?error=1 or testing.php?error=2 alll i get is a blank white page.
can any one explain a bit on how this is done?

 

hi code is absolutely fine. but may b the problem is it's treating the $error as a varChar not Number so please update code in this way.

$error=$_REQUEST['error'];
switch($error) {
	case "1":
		echo "Error Number 1";
		break;
	case "2":
		echo "Error Number 2";
		break;
}

PHP:

 

Thank you i just tryed that code out and it worked.
tell me can the same method be used when doing a if statement?
it seems as if it can by just using request method.

 

i have 1 more question regarding this how do you get a page inside a page like the code you posted that helped now my page can do test.php?error=1 now what if i want my page to do like test.php?error=1&test=1 and that takes me to the test=1 page is that possible?

 

use include inside the if statements.. or put the include inside a div container for css purpose

 

what do you mean include inside the if statements?

so far i have

$error=$request['error'];
switch ($error) {
case "1":
echo "error 1";
break;
case "2":
echo "error 2";
break;
}

now i want to take this switch statement and make the test.php page go to test.php?error=1&e=2 now the ?error=1 part works but i cant seem to make the page work with e=2 it always gos back to the main page of the test.

 

Here is what i am trying to complete.
i am making a php fusion type page for movie listing.
Now when the user clicks a categorie for movies say Horror the page movielist.php will go to horror like movielist.php?state=Horror now that works but i want the horror page to only display 10 movies per page so that means the sub page Horror needs to have a &page=1 added on to it.
so the link would be movielist.php?state=Horror&page=1 now state works that displays the movies but the &page=1 part does not work that just takes me back to the main movielist.php page.
so my question now is how do i add a subpage on a subpage so that the &page=1 will work properly.

 

i can't understand what you want. if you uploaded your site then give me link i'll help you out regarding this issue

 

sure my site is demons-revenge.com/MovieList.php now thats my page so far.
when you go to the url your notice that it has 4 categories Horror Comedy Action and Drama now when you click horror the horror movies display but what i want now is for that page to have a second page added on the url will be demons-revenge.com/MovieList.php?state=Horror
and i want that horror page to have new pages on it so that the movies will show 10 per page.
