POST additional fields

[rondog]

Hey guys I have a form, but on the form you are able to add extra fields. My question is how would I POST those extra fields? The way I always do it is $_POST['field_name'], however how would I know if theyve added new fields. Here is an image of what the field looks like so you get a better idea of what im talking about.

Post on the code and we'll add fixes.

It is hard to explain something by not knowing the background.

If you use a HTML array name as the field name="some_name[]", you can just iterate over the resulting $_POST['some_name'][] array using php's array functions, such as foreach() and/or count()

you could count the elements in the $_POST array - ie if form initially starts with 4 fields and the count of $_POST array is 8 then you know 4 fields have been added

This looks like exactly what I need. Thanks for the ideas guys.

Hey, another questions regarding this. Why does this for loop not work on the other array fields?

//--> CONTROLLERS
$system_controllers_qty			= $_POST['system_controllers_qty'];
$system_controllers_make		= $_POST['system_controllers_make'];
$system_controllers_model		= $_POST['system_controllers_model'];
$system_controllers_serial_no	= $_POST['system_controllers_serial_no'];

for ($i = 0; $i < count($system_controllers_qty); $i++)
{
	echo "qty " . $system_controllers_qty[$i] . "<br/";
	echo "make " . $system_controllers_make[$i] . "<br/";
	echo "model " . $system_controllers_model[$i] . "<br/";
	echo "serial_no " . $system_controllers_serial_no[$i] . "<br/";
}

 

This only outputs the $system_controllers_qty, yet if i do a print_r on each, they all contain data. In theory, they will all contain data even if its an empty string.
