php function from form?

[RaythMistwalker]

<form action='<? function(); ?>'>

 

I already know this doesn't actually work so does anyone know any way of calling a function that is on the SAME page using a form?

You mean as the form is submitted? ..

 

<form onsubmit="myfunction();">

Sorry, didn't spot "PHP" in the title. No, strictly not. PHP isn't event driven like JS - although you could use AJAX to achieve this.

$action = function();

<form action="<?=$action?>"

Nope. The action tag sends POST data, GET data, or calls a js event. AJAX will (easily) be required to send the POST/GET data to your PHP function, keeping it on the same page though. AJAX isn't too hard.

HUH?

Nope.

The method determines how the form data is sent. The action is merely a link extended to the submit. The submit triggers the browser to either append the data to the action-url or pass it in the body of the request(what is returned) as determined by the method as modified by the type. Once the request is processed the action is the "link" the browser uses to contact the server and submit the request body to.

This never worked it just started automatically running the function when i only need it to happen when the form is submitted.

If you want call a PHP function when the form is submitted. Then you'll need to do something like this

 

<?php

function some_function()
{
    echo 'form submittted';
}

if(isset($_POST['submit']))
{
     // call function here
    some_function();
}

?>
<fom action="" method="post">
  SOME FIELD HERE
  <input type="submit" name="submit" value="Submit" />
</form>

another small function question.

I know they are formatted as:

 

function name() {
}

or if i have a variable,

function name($var) {
}

 

Say it has 2 variables am i correct in saying it is done like,

function name($var1, $var2) {
}

and to call it would be

name($var1, $var2);

 

Also in the actual function declaration does it set the variables sent (say name(1, 2) then would $var1 = 1 and $var2 = 2?

Yes correct. For more information regarding functions please read this
