[SOLVED] Variables within $_Post?

[chester]

I have a form of undetermined length. I generate form field names with a loop. On the process page I would like to access the $_Post data with another loop. My attempt does not work:

for($i=0; $i<$num_rows; $i++){
	$temp = "'update_status".$i."'";
	echo $temp."<br>";
	echo "Status".$i." : ".$_POST[$temp]."<br>";
}

Does anyone have a suggestion on how to do this? Thank you.

Do you want to access all of the POST data or just ones that start with update_status in the name?

Revraz - If I can get it to work with this field name it should be easy enough to apply it to other ones.

 

Rhodesa - Thank you for that link, it looks like it may be helpful. My form now looks like:

echo "<select name=\"update_status[".$i."]\">";

and my process code looks like:

for($i=0; $i<$num_rows; $i++){
	echo "Status".$i." : ".$_POST['update_status[$i]']."<br>";
}

Am I not accessing the array correctly?

Ack put the index in the wrong place. This works:

	echo "num rows:".$num_rows."<br>";
for($i=0; $i<$num_rows; $i++){
	echo "Status".$i." : ".$_POST['update_status'][$i]."<br>";
}

Thanks a ton for the help guys!
