Php or mysql problem??

**gspabla** · May 10, 2009, 10:47

the main problem is when a user uploads a photo to my site, the script converts the file name to something like 863d56ec9a75c15fbad89e8c046f43e1.jpg, and storing this file name to mysql database, and everything was doing fine.
but now when i try to upload a pic, after uploading the pic is not appearing coz the entry now in database is like http://www.sitename.com/memphoto2//5...2feb7d739adjpg
(note extra things like site link, foldername, double back slash, and no dot before jpg in the last)

my hosting provider told me that they re-installed or upgraded GD Library (and may be something else) on server 2-3 days back.

and i havnt change any code or anything in site from 15 days
so what do u think where the problem is???????

so what do u think where the problem is???????

In your code, probably.

Can you post it here?

It seems the problem lies in the ImageUpload class. Care to post it?

**gspabla** · May 10, 2009, 13:16

this is the content from file php4upload.class.php

PHP Code:

Try Changing:

PHP Code:


$this->new_name = md5(time()).$ext;
move_uploaded_file($this->_params['tmp_name'], $this->_upload_dir.$this->new_name);
$this->imgurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '/', $_SERVER['PHP_SELF']).$this->_upload_dir.'/'.$this->new_name;

To:

PHP Code:


$this->new_name = md5(time()) . '.' . $ext;
move_uploaded_file($this->_params['tmp_name'], $this->_upload_dir.$this->new_name);
$this->imgurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '', $_SERVER['PHP_SELF']).$this->_upload_dir.'/'.$this->new_name;

Of course, more than one upload in one second (which is very possible) will cause an overwrite. Maybe something like:

PHP Code:


do{
    $this->new_name = md5(rand());
}while(file_exists($this->_upload_dir . $this->new_name));

This will help with combating overwriting a file, though hypothetically isn't totally strong because of race conditions.

**gspabla** · May 10, 2009, 14:18

ok. lemme try this

**gspabla** · May 10, 2009, 14:27

ok. the problem solved a little.
its now adding a dot before jpg now
but the
http://www.sitename.com/memphoto1//
is still the extra thing added in mysql before the fcb317005328d64b8d51c1ed5dac2604.jpg

please help me out i know u r trying

**Jake Arkinstall** · May 10, 2009, 14:38

Well, you now know the problem is in your code, now it's your turn to try and find the error.

For many reasons really. Firstly, you need to learn how to debug your code. Secondly, I'm heading to bed now and I don't have time to read through the code again

Good luck,
Jake

**gspabla** · May 10, 2009, 14:42

okk. thanx jake for helping this much,
well im a fresher for this php and mysql, and i m not able to understands these codes now
so can u please check again when u wakeup or when u free???

goodnight for now, and thanx again for helping

hope to c u back soon

**gspabla** · May 10, 2009, 14:44

btw i m still in shock how a good running site can change its code itself???
nobody has ftp or any other details, only me
and i havnt touched anything in this site from few days
is it possible????

**ferrari_chris** · May 10, 2009, 14:51

Try changing this:

Code PHP:

$this->imgurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '', $_SERVER['PHP_SELF']).$this->_upload_dir.'/'.$this->new_name;

to this:

Code PHP:

$this->imgurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '', $_SERVER['PHP_SELF']).$this->_upload_dir.$this->new_name;

At the end of the line, I got rid of the slash before the name of the file.

**gspabla** · May 10, 2009, 15:04

hmm the problem is still the same just its single / rather than // before file name now
