I'm trying to group dynamic form values to Insert into a database using php and mysql.

The background is that I'm trying to develop a web based Football Prediction League.

I'm retrieving the following values from my Fixtures table

Fixid, Team1Name, Team2Name

and populating a HTML form where the user will enter, obviously enough, the goals for either team

My HTML form displays
Team1 Name Team 1Goals Team2 Goals Team2 Name

I want to submit this form to another page which will insert the following values into a Prediction table

Prediction Id, UserId,FixtureId,Team1 Goals, Team 2 Goals

The code is

HTML Code:
<form name="fixtures" action="target.php" method="get">
<table class="fixtures">
<th>Team 1</th><th>Goals</th><th>Goals</th><th>Team 2</th>
PHP Code:
while ($row $res->fetch_array(MYSQLI_NUM)) {
'<input type="hidden" name="fixture[]" value ="'.$row[0].'">';
'<td>'.$row[2].'</td><td><input type="text" name="f'.$row[0].'t1g" id="f'.$row[0].'t1g" value="" maxlength="3" class="fixtures" /></td>';
'<td class="fixtures"><input type="text" name="f'.$row[0].'t2g" id="f'.$row[0].'t2g" value="" maxlength="3" /></td>';
HTML Code:
<input class="wsubmit" type="submit" name="submit" value="Submit" id="submit" />
<input class="wreset" type="reset" name="reset" value="Reset" id="reset" /
My difficulty is how do I deal with the values coming in when the page is submitted. I've tried doing a foreach loop on the $_GET array for all values but cant seem to figure out how I a group each teams goal prediction with the relevant fixture id
i.e. something like insert into prediction userid,fixid,team1goals, team2goals where fixid = 1 and loop this for, say, 10 fixtures....

What would be the best approach for grouping the variables so I can achieve this ?

Should I change my original form ? Can I incorporate the fixtures array in the hidden field ? Can I group or make an array from the values in the $_GET array ? so many questions!

Many thanks in advance for any help,
