Special characters

flipis

Hi. I'm creating a class to generate HTML objects on the fly. I want to make different kinds of textboxes, and one of them is an e-mail textbox.

I'm using some JavaScript code to check that the values in the textbox are the correct ones. I use the following code:

var filter=/^{(\w+(?:.\w+))@((?:\w+.)\w[\w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$/i}

I actually "copied and pasted" the code.

What i would like to know is if there is any function that would protect ALL of of PHP special characters in this text line. addslashes function protects only some of them.

¿Is there any function that makes this? And, if there is, ¿how do i use it?

Thank you for your support.

Why you're using JavaScript to check the
fields when you're using much more effcient programming tool such as PHP. Why don't you make function or classes that checks the form fields? Just wondering...

hi flipis,

julmis got the right idea...

try this php-function i once found in a book:

function check_email ($mail)
{
$exp="[-!#$%&\'*+\./0-9=?A-Z^{_'a-z{|}~]+";}
$regexp="^{".$exp."@".$exp.".".$exp."$";}
if (ereg($regexp, $mail))
{
$ret=TRUE;
} else {
$ret=FALSE;
}
return $ret;
}

What a great function!

Well, that's a good way to do it. The only thing against it is that you have to reload the page. With JavaScript, you can set up a function to check it before the form is submitted.

Again, you can say, that knowing JavaScript (not that difficult), makes you able to enter wrong data and then, if the following script was not well designed (say you enter data on a db and the fields are not correct), that's not clean.

But, checking HTTP_REFERER is a real good way to know WHERE things come from.

Anyway, i'll use the script. Thanks for the advice.

Problem is that you can turn off the javascript from your browser settings...
