This damn thing is doing my nut! Help please, "if" not working

I'm curious, in what ever editor you use to author your PHP...after your closing tag, do you have another line below that?

Using line tags like this:

67 echo 'response=finished';
68 ?>
69


In my testing, this reproduces the situation you describe.

I can't possibly see how:

PHP Code:

---

echo "&retval=1&imageCount=".$i; 


---

will return a space after the =1 after retval. Seems like something is corrupting the HTTP stream between PHP and flash! Very strange. Have never seen this in 8 years of using PHP! Which version are you using?

Also I don't see how:

PHP Code:

---

echo "&retval=1&imageCount=".$i."&"; 


---

fixes the problem as the issue is with retval and not imageCount!!

Did you try my second suggestion for altering the flash movie, so that it strips the space from retval before doing the comparison? That works a treat too...

The php code is above!
I use DW8 as my default editer

Open your PHP file in DW8. After the final closing PHP tag, do you have anything else? Especially a blank line?

Thanks,

This is all that is in the php file minus the php tags

PHP Code:

---

if ($handle = opendir($_GET['model_id']."/model_pics")) { 
$i=0; 
while (false !== ($file = readdir($handle))) { 
if ($file != "." && $file != "..") { 
if(substr_count($file, '_main.jpg')==1){ 
// 
}else 
if(substr_count($file, '_popup.jpg')==1){ 
// 
}else{ 
$i++; 
} 
} 
} 
echo "&retval=1&imageCount=".$i; 
closedir($handle);

I don't want to look at your code. I want you to look at your code in your editor and see if there is anything after the final closing tag. ;)

php file is attached

Just curious if you ever figured out what was causing the extra white space characters? I understand from Gypsy's posts that if you have additional whitespace after the PHP closing tag, that the whitespace gets sent to flash and it interprets it as part of the previous string. Which is why the additional '&' symbol works. However, your 'imgList' script doesn't seem to have any whitespace after the closing tag.

Nope still none the wiser as to where the white space is coming from.
