function with unknown amount af parameters,

[blueman378]

Hi guys,

 

Well basically i have a form. a coder can edit this form say ut has username, password, email, location

 

by default, the user can come in and add some more fields,

 

now my script validates this form.

 

but the question i was wondering, i dont know the amount of fields the coder will add, so im thinking for my function how would you go about passing an array to it?

 

is it jsut a case of setting a variable to contain the array eg $form = $fields[fieldname][value]

 

and then to send it to the function: my_function($form)

 

would that work?

never mind, 5 seconds thinking and i had the answer

 

<?php

function show_values($array)
{
foreach ($array as $key => $value) {
   echo $key." - ".$value."";
   }
}

show_values($_POST);
?>

well here's half the answer,

 

but now i need a way to add in an extra value to $_POST

 

because instead of having just

 

name=>value

 

i need name=>type=>value

 

any ideas?

 

<?php

function show_values($array)
{
foreach ($array as $key => $value) {
   echo $key." - ".$value."";
   }
}

show_values($_POST);
?>

 

 

(wouldnt let me edit my post)

Just check to see if the value is an array and recursively call your function. If you just want to see what's in $_POST use the print_r function:

 

<?php

function show_values($array)
{
foreach ($array as $key => $value) {
             if (is_array($value)) show_values($value);
   echo $key." - ".$value."<br>\n";
   }
}

show_values($_POST);
?>

or

<?php
echo '<pre>' . print_r($_POST,true) . '</pre>'
?>

If you want the type, take a look at var_dump

 

I take it this is for debugging reasons?
