How do I POST values to a function?

[rsteven]

Hi All,

I have a php script which has lots of functions. How do I post from a form so that I can pass a set of values to a particular function?

eg.

register.html ----------------------------------------------------------------

<form method="post" action="user.php?action=user_register">
<input type="text" size="40" name="real_name">
<input type="text" size="40" name="password">
</form>

---

user.php ---------------------------------------------------------------------

function user_register($real_name,$password)

{ .....function code......}

---

Perhaps I am doing this all wrong... Should I have the form HTML on the user.php??

Thanks in advance :-)

<form action="" method="POST">
real_name: <input type="text" size="40" name="real_name"><br> 
password: <input type="text" size="40" name="password"><br> 
<input type="submit" name="submit" value="submit">
</form>

<?php
if (isset($_POST['submit']))
{
	function echo_all_caps($real_name, $password)
	{
		echo strtoupper($real_name) . '<br>' . strtoupper($password);
	}

echo_all_caps($_POST['real_name'], $_POST['password']);
}
?>

By using the superglobal $_POST...

// user.php 
function user_register($username,$password) {
  // ...function code...
}

// Call the function
user_register($_POST['real_name'],$_POST['password']);

If I have lots of functions how do I specify which one I want to pass the values to?

Is it ok to use:

if ($_GET['action'] == "user_register"){

user_register($user_name,$password);

}

...and url "www.domain.com/user.php?action=user_register"

Or is this a poor way to achieve this result?

???
what do you mean? simply call the functions you want with whatever arguments you want.

say I have a form called add_user and I want to pass the values from this form in an html (separate file)to a php script which contains a library of functions. I want to know the best way to pass the values to that particular function.

Should I be doing this as I said above? and using a case to check the action against my list of functions?

i'm afraid i still don't understand your question. let's backup

-you have a form (HTML)
-you have a form handling script (PHP)

the form handling script deals with the data passed via the form. if you have a library of fucntions they can reside in the form handling script itself or in a separate file that you can [man]include[/man] as necessary (this is a very common way to organize your scripts). your question seems to be what conditional logic you need to use. that's where you've lost me. what condition are you talking about?

I have a form in a static html file.

I wish to send / pass / submit the info from this form to a script which contains functions. I want the processing script to know which function I am trying to access and pass the values to it accordingly.

I am currently:

In static html page:

<form method="post" action="user.php?action=funtion_name">
<--- fields--->
</form>

So these submitted values will be sent to the php script...which then has to receive and decide what to do with these values...

I am currently coding:

$action_type=$_GET['action']; //receives the values submitted

switch ($action_type) {

case function1: //check if the 'action' is function1
fucntion1($val1,$val2) //run the function with the values
break; // exit as action has been done

case function2:
function2($val1)
break;

case function3:
function3($val1)
break;
}

I really want to check that this is the best way to carry out this kind of value passing. It seems to work but I am concerned that it might not be best practise as I am only learning php this week.

Thanks for your help.....

i think i understand now. what you are describing should work fine. you can pass the fucntion name via GET or POST (via hidden fields). however you said that the form is completely static. why then would you bother conditionally running different functions if the static form is always sending the same function name? perhaps you have several static forms that you want to have share a common form processor?
