Help With Functions?

[Kryllster]

I have written some code which I am not trying to put in a function but I am new to functions so I am not sure what to do. It is an Email account activation script I know it works as it is now but I wanted to try my hand at making it a function.

 

=========================

$activationkey = hash('adler32',rand());
function emailActivate($email_to,$email_subject,$returnlink,$email_message,$activationkey){
$email_to = $_POST['email'];
$email_subject = "Email Verification and Activation";
$returnlink = "http://ferentus.netai.net/php/verify.php?code=" . $activationkey;
$email_message = "Welcome to The Ferentus Text Website, Please verify your email and activate your account by clicking the link.\n" . $returnlink;
mail($email_to,$email_subject,$email_message);
}
?>

 

========================================

Im stuck as to how to use this or even if it is correct? Any comments would be appreciated!!

Yep, you seem completely lost. Have you tried reading the manual?

Thanks for the reply. I am looking in the manual now altho it doesnt seem to help much I will also look at some online tutorials.

Short version: functions don't run automatically. You need to call them by using

function_name(variables, variables);

 

$_POST will not work in a function so you need to call them by the variables inside the parentheses

 

ie:

 

functions.php

 

// variables can stay the same it doesn't matter just as long as they coincide
function bored($bored_renamed, $tired) {

echo "Bored = $bored_renamed";

}

 

whatever.php

<?php
require("functions.php");

bored($bored, $sleepy);

?>

I think you need to RTFM re superglobals

<?php
// mail going to the person who signed up for game
$email_to = $_POST['email'];
// self explanatory
$email_subject = "Email Verification and Activation";
// needed help from emeri for this
$returnlink = "http://ferentus.netai.net/php/verify.php?code=" . $activationkey;
//send the message
$email_message = "Welcome to The Ferentus Text Website, Please verify your email and activate your account by clicking the link.\n" . $returnlink;
// action taken
mail($email_to,$email_subject,$email_message);
?>

This is the way I had been using it is it even necessary to use it in a function??
