if you had multiple hidden fields they would each have to be called name[]

example

<input type="hidden" name="iput[]" value="something">
<input type="hidden" name="iput[]" value="something else">
<input type="hidden" name="iput[]" value="another thing">
<input type="hidden" name="iput[]" value="one more thing">

then on the processing page

$hiddenArray = $_POST['iput'];

foreach ($hiddenArray as $var) {
 //do something with each value
}

if you wanted them all in one hidden field, which may for example look like this

<input type="hidden" name="iput" value="something,something else,another thing,one more thing">

you would then do

$hiddenArray = $_POST['iput'];

$components = explode(",",$hiddenArray); //where as , is the string seperator, you could of course use something else like |

foreach ($components as $var) {
 //do something with each value
}
