You can send a variable by GET method ("do=partyform"), check it in php and call right function.

In one form put

<input type="hidden" name="from" value="ParytForm.html" />

and in the other:

<input type="hidden" name="from" value="clientForm.html" />

then in your PHP code distinguish your input:

if ('clientForm.html' == $_POST['from'])
    {
    // do stuff
        PartyForm();
    }
else if ('ParytForm.html' == $_POST['from'])
    {
    // do other stuff
        clientForm();
    }

I adapted ParytForm.html for fun ;-)

To do this, you will need some way of the PHP program to distinguish between the two requests. This can be done by adding a parameter to the URL the form is submitting to, or changing the name of the submit button. I tend to prefer the URL method though, because it is cleaner.

for example

Form 1 could be

<form method="phpfilename.php?dofunction=1">

Form 2 could be

<form method="phpfilename.php?dofunction=2">

Then, on your PHP file, you could check which form is sent using

$form = $_GET['dofunction'];

if ($form == '1') doFunction1();
else if ($form == '2') doFunction2();

You do [not want to use $_REQUEST](http://stackoverflow.com/questions/1931587/is-it-wrong-to-use-request-for-data). – Linus Kleen Dec 19 '10 at 14:54
True. Lazy coding using a catch-all! Example code changed to reflect. – Codemwnci Dec 19 '10 at 15:04

You can do this multiple ways, one way is to include a hidden field in each form, and then use a conditional after you submit to run the right function.

Your html code below

<form action="action.php" method="post">
...
<input type="hidden" name="formName" value="PartyForm">
<input type="submit" value="Submit">
</form>

<form action="action.php" method="post">
...
<input type="hidden" name="formName" value="ClientForm">
<input type="submit" value="Submit">
</form>

and then in your action.php or whatever you call the page you submit to

if($_POST['formName'] == "PartyForm"){
  partyForm();
}else if$_POST['formName'] == "ClientForm"){
  clientForm();
}

The best way to do this (I think) is to use the PHP include() function. Use your forms inside a .php file (which can include HTML only), and include the functions file in both form files.

Then, just use action="clientForm()" to call the function when the form is submitted.
