Looping thru $POST

[mjhaston]

I'm not sure if I need to use arrays or if I can do this with variables. I have a working score reporting system that has 20 entry lines hard-coded to record entries. I'm trying to change this up and make it flexible.

Basically I need to output a form:

Team A1 - Score A1 - Team A2 - Score A2
Team B1 - Score B1 - Team B2 - Score B2

Then I need to read these variables and store them in the database.

Right now I'm okay on the form page, but if this is wrong tell me. I am looping through my MySQL database and writing this out:

<input type="hidden" name="<?php echo "home_team_" . $i; ?>" value=<?php echo $info[0]; ?> />

Seems to work.

My problem is on the receiving end I'm not sure how to loop thru to receive these variables. Right now I'm hard-coding it:

if ( $_POST[home_team_1] ) {

you could use a for loop :

$n = 20
for ($i=0; $i < $n; $i++) {
  $input_name = 'home_team_' . $i;
  $var = $_POST[$input_name];
}

An alternative approach would be to ditch the $i counters altogether; just output HTML field names such as 'foo[]' and then $_POST['foo'] will be an array of values when the form is submitted. A simple [man]foreach/man loop would allow you to loop through the resulting array.
