Signatures

[CPC900]

Ok, I have read the forum, but don't think the answer is there?!

I get this error now, and not sure why or what I might have done to get it:

Warning: imagepng() [function.imagepng]: Unable to open '/home/########/public_html/CPC//lib/signaturesCPC0001.png' for writing: Permission denied in /home/########/public_html/CPC/core/common/PilotData.class.php on line 1001

Now I noticed a double "//" above in the "/home/########/public_html/CPC//lib/signaturesCPC0001.png" part and was wondering if that is the problem? If it is, I have no idea why there are 2 slashes there?!?

Line 1001 in my PilotData.class.php is:

imagepng($img, SITE_ROOT . SIGNATURE_PATH . '/' . $pilotcode . '.png', 1);

Make sure that folder the signatures has 777 permissions.

Thanks the error, its unable to create the image.

[CPC900]

Yeah, it is set to 777, thanks. But I was asking why there were double slash's in the address. I think therein lies the problem. I just don't know why that would have changed?!

You could try to see if this is what is located in your PilotData.class.php to see if it is missing something.

/**

It may also be in the way the path is written. You can see if the signature is supposed to be written after the CPC/ or the CPC. If it is after the CPC/ then you might want to remove the / or just route it to the full URL.

I will review the code when I get home later. As for the "/", I did remove that just to see, but no luck. I will copy and paste your code here to see. But I was wondering if I would have changed the PilotData.class.php code for some reason?! I sure don't remember why, if I did. Thanks, will keep u posted.

[simpilot]

It is a directory issue, I ran into the same thing. For my fix I just has to use the complete absolute url in the ranks image setting.

http://www.yoursite.com/path to image

not

/path to image

[Nabeel]

The double slashs doesn't matter

[CPC900]

Ok, I will look into it. I have had NO time to fix it since I last posted. Thanks for the input Dave, I will take a look!

It's weird though, why would it have changed?! Oh well. Probably something I did

[CPC900]

Thanks Dave, that fixed it

Bruce

[CPC900]

Correction. It did not fix it. I don't get the error pop up, but it does NOT change the signature with updated hours, nor will it change the sig pic from the pilot profile. So something, somewhere, I must have broken

[Nabeel]

Make sure permissions are ok, sometimes they change b/c of server side stuff

[CPC900]

I can't remember now, is there a list for PHPVMS of what folder and file permissions, SHOULD be set to?! Sorry, if that seems like an obvious question, but I am at a loss right now

[Nabeel]

775 or 777, I'd ask your host what they recommend, it depends how they've setup file/folder ownership.

[CPC900]

Dave, sorry to come back to this after so long, but I never did get it fixed

As for what you said above, where EXACTLY did you mean, when you said:

It is a directory issue, I ran into the same thing. For my fix I just has to use the complete absolute url in the ranks image setting.

http://www.yoursite.com/path to image

not

/path to image

[CPC900]

Sorry Dave, but I need to know exactly where the code goes, and what the correct line of code actually is

[simpilot]

It has been a while but I think this falls back to the pilot rank images and not using relative paths in the admin center.

In the pilot ranks admin panel instead of

/lib/images/ranks/newhire.png

Use

http://www.mysite.com/lib/images/ranks/newhire.png

[CPC900]

Ok, I finally fixed it, after reading over and over again what you all told me Sorry, but sometimes, I am a total MORON apparently. It is good now. The folder permissions were fine, but I made the .png files all 777 in the signatures folder and all is fine. The individual .png files were 644 or something. Not sure why that was.
