how to edit nested arrays in a form?

[falcondriver]

lets say i have this nested array:

$this_guy = array(
"name"=>"a guy",
"address"=>array(
"street" => "s. mile",
"zip"=>"123",
"city"=>"mooflake town")
"email"=>"spam@hotmail.com");


now how can i make a form out of this array (some smart function maybe)? i want to be able to edit this array, and i already have some function to display the structure and data, but how do i "address" the fields and read them in again?

has someone an example script that takes an nested array as input and returns a <form action="."> so that you can edit this array and use $_POST as new data? (hope someone can still follow me...)

Uhm........
If the array is always with the same structure, you can simply do:
<form action="action.php" method="post">
Name: <input type="text" name="name"><br />
Address:<br />
- street: <input type="text" name="street"><br />
- zip: <input type="text" name="zip"><br />
...
</form>

And then in your "action.php" script (the one that receives the POSTed data) just do:
$this_guy['name'] = $_POST['name'];
$this_guy['address']['street'] = $_POST['street'];
...

I hope I understood your question, thou... ;)

Something like the following might work, modify accordingly of course.

Blargh, mis-read. Yes it's possible, if you still haven't solved it by the time you read this let me know and I'll help you out.


<?php

$this_guy = array(
"name"=>"a guy",
"address"=>array(
"street" => "s. mile",
"zip"=>"123",
"city"=>"mooflake town"),
"email"=>"spam@hotmail.com");

form($this_guy);

function form($array)
{
foreach ($array as $k => $v)
{
if (is_array($v))
{
foreach ($v as $key => $value)
{
echo "$key: <input type='text' name='$key' value='$value' /><br />";
}
continue;
}
echo "$k: <input type='text' name='$k' value='$v' /><br />";
}
}

?>

thanks, problem solved:


function edit($array, $root) {
$bf = "<ul>"."\n";
foreach($array as $key=>$value) {
$key = $root.'::'.$key;
if(is_array($value)) {
$bf .= edit($value, $key);
}
else {
$name = fieldname($key);
$bf .= '<li><input name="'.$name.'" value="'.$value.'"></li>'."\n";
}
}
$bf .= '</ul>'."\n";
return $bf;
}

function fieldname($address) {
//build correct form address
$data = explode("::", $address);
$formname = "";
foreach($data as $level=>$address) {
if($level==0) {
$formname = $address;
}
else {
$formname .= '['.$address.']';
}
}
return $formname;
}

picouli: sorry, thats not really an option - my array has about ~90 fields or so, im not going to write a static form by hand for this.
