RE: [PHP] Output (Urgent!)
Hi Frederik
Run this code. It does what you want it to.
In your original code you compared two strings in the IF-statement.
When the $resolution gotten from your JavaScript returned '800' it would
have a lexical higher value than '1024' and thereby do exacely what
you wanted it to - actually the code would always return \1024\ since
your screen resolution would never return a string with a lexical
lower value than '1024'.
By multiplying the string '1024' by 1 you get the integervalue 1024
(that's a trick PHP offers ;) ) which you then compare to the
integervalue 1024.
That's the trick
$resolution = SCRIPT LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT;
echo --.$resolution.--;
if (($resolution*1) = 1024) {
$resolution = 1024;
} else {
$resolution = 800;
}
echo **.$resolution.**;
Venlig hilsen ha' en bra dag,

$resolution = SCRIPT
LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT;
if ($resolution = '1024') {
$resolution = 1024;
} else {
$resolution = 800;
}
echo $resolution;
It always output 1024
At a guess becasue your mixing and matching languages.
If you got the input from a hidden field in a form (perhaps an entry
page?) then it would be possible to get the data you want.

How you want to get a value from client side to php on the same page? Well. Actually I didn't invent the code. I just correcteded it so it worked on my installation. I must admit I was amazed that it somehow worked, but it did.

Re: [PHP] Output (Urgent!)
You aren't getting the value to the PHP script... allow me to walk through
what is actually happening
$resolution = SCRIPT
LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT;
echo --.$resolution.--;
You have just set a variable to SCRIPT
LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT and then
echoed that string. so it looks like you have
--1024-- or whatever your resolution is. if you view source though you see
you really have
--SCRIPT LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT--
and the client browser is just interpreting that JavaScript statement
if (($resolution*1) = 1024) {
$resolution = 1024;
} else {
$resolution = 800;
}
echo **.$resolution.**;
The reason this isn't acting the way you expect is because you AREN'T saying
if ((1024*1) = 1024 {
You are actually saying
if ((SCRIPT
LANGUAGE=\JavaScript\document.write(screen.width)/SCRIPT*1) = 1024) {
You are not actually passing anything from JavaScript to PHP... you are just
tricking yourself =)
