modify an input value before it gets stored in the db

[Rollo_Tamasi]

hi guys, i have a input box which requests a URL from the user, this url gets stored in the db and later gets called by a page which generates a link from the value. A problem might be if the user types in www.website.com instead of website.com as the code i will be using will have the www part already on the php page.

How can i store the value website.com in the database if www.website.com is typed into the form?

Hi.
I think parse_url
should be useful.
Take care.

is there any validation rule that i might be able to use actually?

Hi,

i can suggest you two things.

first: use a regular expressions to check if the input is formated as we need it. For that just use this:

!ereg("^([A-Za-z0-9-]{3,}).([A-Za-z]{2,})+$", "google.com")?print("Wrong Format!"):print("Right Format.");

here we check of string as someTextOrDigits with minimum 3 chars in length. fallowed by dot. and then again only text with more that 2 chars in length.
if the input string don't match with your regular expression template display and error and 'example of right input value'.

and the second way to do this is to use a str_replace and to remove/replace www. from the input string. for example:

$string = str_replace("www.", "", "www.google.com");

this will replace www. in your string and will output google.com instead of www.google.com
i think this is the better way to do it, but it's all your choose.

and excuse my english, it's not my native language :rolleyes:

There's plenty of regexp syntax to validate a URL. Just use [man]preg_match/man (preg is much faster than ereg) along with a pattern that you can google very easily.
