Need help about addslashes

[Anon]

I used a script to upload image into database. The code was working fine. But suddenly from today it showing an error like - "Warning: fopen("","r") - Success in /opt/www/webdev/docs/e-jooti/final_reg.php on line 532

Warning: Supplied argument is not a valid File-Handle resource in /opt/www/webdev/docs/e-jooti/final_reg.php on line 532
Duplicate entry '' for key 1".

the line 532 is like this - addslashes(fread(fopen($pic, "r"), filesize($pic))); I don't know why this error after a long time giving no problem. Any body can help me? I need help immediately.

I can't say for sure, but it sure seems like your database is saying that you are trying to add a duplicate record and that's not allowed.

Duplicate entry '' for key 1".
I'ld look at your database setup. Perhaps your primary key has reached it's limit (if you have an auto incrementing field)?

Just a thought.

The error is:

"Warning: fopen("","r")

and your code is

fopen($pic, "r")

therefore, $pic is null. Somehow, your database contains a null where there should be a filename.
