if / else help

[xcoffeesx]

Hello,
i been trying to make the following script work, and i been having some difficulty cause it's acting weird
here's the script

<?php
if ($IMG_WIDTH < 750) {
(include "/pathname/file1.htm");
}
else {
(include "/pathname/file2.htm");
}

?>

$IMG_WIDTH is a constant which is given by uploading a picture, so to keep the layout of the website the same no matter the width i create 2 files for the headers and footers to load in 2 conditions if the image is smaller or bigger than 750.

now the script is only reading the if part and not the else part when i put the parameter of <, and when i put the == the script works fine.

can anyone help in this ?

thanks for your time in advance

first off, are you sure you mean that $IMG_WIDTH is a constant? because constants do not have $ signs in front of them.  If that doesn't work...

If the else is not executing, then $IMG_WIDTH is obviously less than 750.  But this might not necessarily mean that the width is say, 700.  if $IMG_WIDTH is not set or doesn't exist, then it will read as 0 < 750.

ok thanks for the reply first,
here is the whole thing

i am creating a user send your picture as ecard thing, the user goes to the site upload their picture, then be able to send it to family and friends etc, boring i know but it has a small twist to it.
so when the user uploads the picture or image that's where the $IMG_WIDTH goes in, then the script takes you to a bunch of templates to put up the card together, so the $IMG_WIDTH is a value which is variable once you uploaded, in the file1.htm and file2.htm i set 2 values for the table width of the page one of them is a fixed 750 the other is width={IMG_WIDTH}.

now the script if/else is working on the == 750 the else works fine on the < it just doesn't read the else.

i just tried a small thing which i put a small echo"img=$IMG_WIDTH" on top of the page and it's reading the img width fine just the ELSE statement is not working in the < less than.

Thanks for your time.

okay so you did
[code]
echo "img=$IMG_WIDTH";
[/code]
and it printed out the width.  That means it's not a constant, but a regular variable.  And your if/else statement then looks like this:
[code]
<?php
if ($IMG_WIDTH < 750) {
  (include "/pathname/file1.htm");
} else {
  (include "/pathname/file2.htm");
}
?>
[/code]

according to your code, it should work.  Now, you mentioned

[code]
width={IMG_WIDTH}
[/code]

in this instance,  IMG_WIDTH is being used as if it were a constant, not a regular variable.  somewhere in your script do you have like

[code]
define('IMG_WIDTH', $IMG_WIDTH);
[/code]

because if you don't, you either need to add that so that your use of the constant will work, or else, change it from using a constant to a regular variable with the $

exactly, i added the define, still the same what's weird is the when the == is put the script works fine and reads the else, when i change to < it just stops.

Thanks for helping i will try and figure it out  ???

What happens if you change it to:
[code]if ($IMG_WIDTH <= 750) {
[/code]
