Hi guys simple question this form:-


<html>
<body>

<form action="action.php" method="post">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>

</body>
</html>

and...action.php


<html>
<body>

Welcome <?php echo $_POST["fname"]; ?>!<br />
You are <?php echo $_POST["age"]; ?> years old.

</body>
</html>

NOW... if i had 4 forms on my site would i need 4 "action.php" files one for each or can i put "functions" in the one and get the differant forms to call differant functions in action.php???

P.S please keep it simple as i'm still learning:p

Either way could work. If they are related, you could use if statements (or functions) to decide what action to do. But if they're unrelated, you probably should keep them separate. There's no reason to confuse things if you don't need to.

Dunya, please post a new thread using this link:

Look for the "new thread" image at the top of each forum, above the posts.

The form would submit to the same page, action.php. You don't need to change that part.
There are two ways you could use an if statement:
1. You could check what kind of information has been sent. For example, if 'username' and 'password' were sent, then it must be a login. If not, maybe it's a comment, etc.
2. You can use the form action to send extra information. Use action.php?type=1 and then check for $_GET['type']-- if that has a value of 1, then you can do one kind of action.
Either way, it will be the receiving page that decides what to do with the information.

But again, if you have two unrelated processes, it's best to keep them separate.
