View Full Version : $_POST problem

09-06-2011, 02:38 AM
I have a name input

and for some reason, when I type in ' in the html form it outputs as \'
I don't know why but it is causing problems. Can anyone explain why this is happening?

PHP puts a "slash" in front of special or reserved characters ...

Try this ...

echo "Name: $name";

See what happens.

Thanks, that works. I think the reason why php was doing that was to prevent SQL injections, and I think that is a real smart idea. Now, stripping the slashes works for now, and the way I coded it I don't think it's a security risk... I think it's called magic quotes.

Correct, it is to help prevent injections. It can be safe depending on what is going in the box and who is entering the data into it.

I'd recommend you to read the manual http://php.net/manual/en/security.magicquotes.php (and the sticky http://www.codingforums.com/showthread.php?p=711327#post711327)

It is (supposed) to help prevent SQL injections. Although its among the stupidest things that Zend has introduced.
Fortunately, these will be gone very soon. Register globals are gone as of 5.4, so that's a great start.
