[PHP] comparison operators
Hi All, I have a form where i let people choose a file to upload, but i want to limit them to image files only. So i want to only allow the .gif and .jpg to be uploaded. What i tried doing was this: if ($filename_type == "image/gif") -- upload file otherwise give an error message! but for some reason this doesn't work. It uploads any kind of file without complaint! So what am i doing wrong? Is there another operator to compare strings for instance? Or what is the problem? Thanks! = Heidi Belal ICQ# 32127109 A bus stops at a bus station.

Re: [PHP] comparison operators
Hi:
For compare strings you can use strcmp.
$st1 = "hi";
$st2 = "bye";
if (strcmp($st1, $st2)) {
echo "are different";
}
else {
echo "are equal";
}
The strcmp return 0 when the strings are equal. If the strings are diferent,
return the pos of the char where begin the diference.
I think you can use this without problems.
I can see that you upload files. My problem it's that i can do it. Y use the
form like this.
Send this
file:
My problem is that i don't know how to do the php program that i upload the
file.
Can you help me?.
Thanks.
Best Regards
Diego

[PHP] comparison operators
Hi All! i'm creating this form for people to upload pictures, so i want to be able to compare the type of the file, so that if it's not a .gif or a .jpg i give them an error message! What i am using is: If ($userfile_type == "image/gif") - here it uploads the file otherwise it sends out an error message! but the problem i'm having is that even when i try uploading a .txt it accepts it and uploads it without giving the error message. Is there another way to compare strings? or is == operater correct? or what am i doing wrong? thanks! = Heidi Belal ICQ# 32127109 A bus stops at a bus station. A train stops at a train station.
