echo "<a href='javascript:alert(Please check the missing fields);'></a>";
    }
}

if($check == "yes" && $cm = true && $cf = true  ) {

</div>

Any advices would be super!

Where is your error and what is it?

Hi,

well, to put in in simple words: you are probably familiar with actionscripts, which is quite similar to php. So if you read through that code, there is
a) some initialisation (getting data from the form)
b) the definition of a few functions
c) an if statement that suggests you had called these functions and assigned the results to some variables.
Now, please note that - unlike actionscript - globals (variables outside functions) must be named as such: you cannot use $from inside a function.
There IS a way to return results through a parameter, but explicit return are probably better - they are easier to read.
Like actionscript, single = sign as part of an if(condition) are rarely ever doing something sensible ....
Finally, parameter structure for mail() is destination email, subject, message, headers. You can visit php.net and enter "mail" into that search box on the right side to see the manual page.
Adding these changes, you get somewhere near

Code:

---

<?php

$output = "no";
$check = $_POST['output'];
$message = $_POST['message'] ;
$topic = $_POST['topic'];
$from = $_POST['email'];
$to = "[email protected]";

function checkmail($from) {
    if (!preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/", $from)) {
echo "<a href='javascript:alert(Invalid email Address);'></a>";
        return false;
    }
    return true;
}

function checkfield() {
    global $subject, $topic, $from;
    if ($subject == "" || $topic == "" || $from == "" ) {
echo "<a href='javascript:alert(Please check the missing fields);'></a>";
        return true;
    }
    return false;
}
// now actually call these
$cm = checkmail($from);
$cf = checkfield();

if($cm == true && $cf == true  ) {
mail($to, $topic , $message, "From: $from");
....

BTW: I have not tried whether this thing would work - I have just looked for obvious problems

thanks for the advices i'll check it out! i was trying to use it as

PHP Code:

---

echo "<a href='javascript:alert(Invalid email Address);'></a>"; 


---

but i think it should go like

PHP Code:

---

<?php
header("Location: javascript:alert('what');");
?>

---

which still isnt right :P but its closer to the result i wanted to have

Hi,

I dont think that this will work (or, if it does, it will not work in somebody else's browser)
So I would recommend to return a form again but to pre-fill it with the visitor's response.
A suitable fragment could read

Code:

---

<input type=text name=email value="<?if(isset($_POST['email'])) print $_POST['email'];?>">
