Help... %&$@ File Permissions!!!

[jlpeifer]

I'm totally stumped here and am hoping beyond hope that someone out there can put a cork in my day of coding agony.

I am setting up Cardservice International's Linkpoint's PHP wrapper to work with osCommerce (an open source eCommerce s/w package). I've followed the directions to the T but something's not right and I can't put my finger on it.

The file in question (lpphp.php3) contains a line which reads...

[FONT=courier new]$fp=fopen($myfilename,"w");[/FONT]

$myfilename is a construct of directory information and random variables. The resulting string looks something like this...

[FONT=courier new]
temp/TEMPFILE_20034618823_1
^{    }
|    |
|    --- A randomly generated filename
--- the temp directory off of the web server root
[/FONT]

The lpphp.php3 file itself gets called by another php file via an Include statement. Permissions on the temp directory off of the web root are 777. I coded a simple "fopen()" test to make certain that files could in fact be created in this directory by PHP... which they can.

This being said, the lpphp.php3 seems completely unable to navigate the file creation process. I consistently get an error that reads, "Cannot open Temp File!" I've dug into the code and feel confident that this message is resulting because lpphp.php3, for whatever reason, isn't permitted to create the file.

Apologies in advance for my lack of permissions knowledge. Please help before I pull all my hair out!

Thanks!

does the file create correctly? are you just having problems opening the file?

you may need to not use the temp file and use the actual file by creating the file in some directory located in your web directory.

you have different functions that you can use at the end of strings such as:

name
size

that help you in naming and retrieving the file.

Also, if you are just opening up the file to read, you may want to change you 'w' to 'r'. If I'm not mistaken the 'w' will erase everything in the file. (could be wrong on that one)

Good questions. The lpphp.php3 file needs to create a unique file every time it processes a credit card transaction. I'm not really certain why... it just does. Each of the files created has a unique name that's determined by the date and a random number generator. The "w" setting is AOK since the file is created from scratch every time. I've tried varients such as "a" (just to see what would happen). In the end the problem is always the same. 😕
