Question

All,
I have a form that has some text inputs, checkboxes, select box and a textarea. I want to submit the form with PHP using a submit button to a page for processing.

That part is fine but what I would like to do is basically get the results into an array so I can do a foreach loop to process the results.

Basically I’m trying to create a dynamic form the submits to my backend processing script and don’t want to hard code in the post values like the following:

$var1 = $_POST['var1'];
echo $var1;
$var2 = $_POST['var2'];
echo $var2;

Does anyone know how to go about doing something like this or give any recommendations?

If there’re no other data in your POST but these generated elements, just do

foreach( $_POST as $key => $val ) {
    // do your job 
}

and process what you have. If you want to mix your generated entries with predefined you may want to put these generated in nested array:

<input ... name="generated[fieldname]" />

and then you iterate

foreach( $_POST['generated'] as $key => $val ) {
  // do your job
}
