Function as pages

Double_M

Hey all,

Right i have a login screen but i want it to just change to another function when logged in. so when the login button is pushed it show the menu, which is another function. But all it does is show the menu above the login screen on the page. The login doesnt go away.

How do i send to other functions without haveing the previous function still viewable above the first one? Slightly confused. do i use switch case statements? or $_REQUEST? or seomthing liek that?

Any help would be great. 🙂

Hi,

This is very dependent on your coding preference.

You could use if (<something>) { <do something> } else { <do something else> }

Ive tried the if statement before, and it says cannot modify header. I know of this problem.

I send the post variables to the same function as the form and try to call the desired function but it either says cannot modify header or it just apears above the other function in the page. How do i only show the function it should go to and not both?

Hope it makes sense :quiet:

Thanks.

And do you know what it means? (If you don't, here's a hint: search the forums for "cannot modify header").

second hint: It has no link to the if/then statement.

If you really get buggered down.. Post the faulty code, and why you couldn't find the solution to "cannot modify header" on the forum (You should get somewhere around 15000 hits, I think ;-) )

Ok you lot, im gonna post some code here. I just cant think of what to do.

Just it to go to another function and not show the previous one, is that too much to ask? :/

Thanks for any help.

and where do you use the login script?

Weedpacket

And what exactly does the error message say? Or are we expected to guess at most of it?

scrupul0us

just heads up:

GLOBAL $HTTP_SERVER_VARS, $HTTP_POST_VARS, $_HTTP_GET_VARS, $HTTP_POST_FILES;

are depreciated and replaced by

$_SERVER, $_POST, $_GET, $_FILE

and dont need to be defined/declared

The login is just a button at the moment, and when clicked i want it to send to that menu function. But it either says header cannot be modified or the new function just pears above the button.

I know cannot modify header means that it is being produced above the header in the page. But how do i get around this if my code is producing the header?

Fix the code. We can't help you with knowing which bit of code to fix unless without

Hint: the error message tells you which line of which file is the start of the trouble.
