File_Exists() Help

[White_Lily]

Okay, so i need my CMS to determine whether a page exists or not without the user guessing, I looked up file_exists() on php.net, read what it does, and copied the code into mine and just changed the echos and $filename variable to what i needed them to be, the problem is it says completely the opposite of what its supposed to be.

 

if i say:

 

$filename = $GLOBALS["siteUrl"].$fetch["pageLink"];

if(file_exists($filename)){
echo "file exists";
}else{
echo "file not found";
}

 

It says the file does NOT exist whereas if you go into the directory im pointing to, right there in front of you is the file.

 

However,

 

If i say:

 

 

$filename = $GLOBALS["siteUrl"].$fetch["pageLink"];

if(!file_exists($filename)){
echo "file exists";
}else{
echo "file not found";
}

 

It then says the DOES exist...

 

Any ideas why its confusing the two?

 

P.S: Ive echoed $filename and it shows the CORRECT file path, even including the file name.

Are you sure it's the correct path, from the root of the filesystem, or relative to the script you're running it in?

 

In your second code block, you neglected to reverse the outputs. The way it reads, if the file doesn't exist, you'll get the "file exists" message.

You need to specify an absolute path on the server, not a URL

[White_Lily]

$GLOBALS["siteUrl"];

 

is: http://localhost/

 

and according to php.net, that type of file path IS supported by file_exists()

 

and yes, the file path is correct.

My reason for putting !file_exists() on the success message was to prove that it says the doesn't exist, even though the file i want to prove exists is staring me in the face.

Without specifics, it isn't possible to help you much more with this . . .

[White_Lily]

the file_exists() code:

 

$filename = $GLOBALS["siteUrl"]."template/".$fetch["pageLink"];

if(file_exists($filename)){
echo "<option value='1' selected='selected'>Yes</option>";
}else{
echo "<option value='0' selected='selected'>No</option>";
}
echo "</select>";

echo $filename;

 

the echo $filename:: http://localhost/template/index.php

 

the $GLOBALS["siteUrl"]; code:

 

$GLOBALS["siteUrl"] = "http://".$_SERVER['HTTP_HOST']."/";

Are you using MAMP/WAMP/XAMPP/etc. with a non-standard port number that would need to be included? Is there a reason you aren't using a filesystem path, perhaps with $_SERVER['DOCUMENT_ROOT'] to do this?

[PFMaBiSmAd]

file_exists is intended to work using file system paths. It does work with some URL wrappers, but http isn't one of them.

[Pikachu2000]

I was starting to think that, but couldn't find anything in the manual that explicitly stated one way or the other. Where did you manage to find it?

[PFMaBiSmAd]

The file_exists requires stat() functionality. Here's the list of the http supported functionality - http://php.net/manual/en/wrappers.http.php

Excellent, thanks!

Hey, sorry for not replying, fell asleep after staying up half the night with my kid lol.

 

I will give these suggestions a go later and will post the results :-)

[White_Lily]

Okay, so ive just tried using $_SERVER["DOCUMENT_ROOT"];

 

and it works! thanks guys for all the help
