[SOLVED] Captcha Problem...

[darkfreaks]

imagecreatefrompng(captcha.png) [function.imagecreatefrompng]: failed to open stream: No such file or directory on line 19 of captcha.php

 

what exactly is wrong on this line? someone told me i need to change the path what path?

 

 

[Fadion]

imagecreatefrompng('captcha.png')

 

It needs a valid path and that path to be string.

 

what exactly is wrong on this line? someone told me i need to change the path what path?

 

The path of the file is its unique location in the file system, being made of directories and finally the actual file.

[darkfreaks]

i dont understand ???

[Fadion]

What u dont understand, to put captcha.png between quotes, or what a path is?

[darkfreaks]

welll i dont get why its erroring. i have it in quotes.

[Jessica]

You need the full path, if captcha.png is NOT in the same directory as this file.

[darkfreaks]

thats what im not getting it is in the same folder? :-\

[Jessica]

Show us the actual code please. And if possible, a link to the page.

So that file is in the folder Guestbook?

Why don't you just put in the whole URL and see if that works.

header('Content-type: image/png');

[darkfreaks]

if i put header it wont work properly and error.

[Fadion]

if u dont put the header, u wont have an image displayed, but those strange characters.

[darkfreaks]

oh no it works fine without it but i think its because something jesi suggested i do in the html for my captcha form

[darkfreaks]

form.php

 

 

<img src="http://www.wiccan-gathering.com/lilysgraveyard/addons/Guestbook/guestbook.php?t=<?php print time(); ?>" border="0"> 

[Jessica]

guestbook.php Is not the same file as captcha.php.

You need the header() that was posted in order to make an image.

[darkfreaks]

im still getting the error about imagecreatepng('captcha.png');

[Jessica]

You have so many pages, I don't know where you're getting this error. On the page which is supposed to be generating another image? And you tried using the whole URL?

 

Post the most recent version, each time, because you have several files you're talking about and the error.

[darkfreaks]

according to my error log

 

 

imagecreatefrompng(captcha.png) [function.imagecreatefrompng]: failed to open stream: No such file or directory

[Jessica]

Well I guess we can't help you.

is the link to the tutorial maybe i missed something?

[Jessica]

It looks like you don't have the header line in still.
