question about using POST as an array

[Evan_Morgan]

ive never used post when i dont know what the input was, the input is in this case a match id and a team name, and i have no idea what to do.

here

basically i dont know how i should access the values, try out the form and see what i get as output.

ok, i just clicked a few of the radio buttons and submitted the form and got

Array
(
[PHPSESSID] => d918448ce9197c4ccccc2f947a569dc1
[11] => bolton
[12] => arsenal
[13] => draw
)

so i'm guessing phpsessid is a hidden field and 11, 12, and 13 are the radio button names

you can just access these using

$_POST['PHPSESSID'];
$_POST['11'];
$_POST['12'];
$_POST['13'];

yeh sorry i tried to explain but it was hard, heres the code

<?

session_start();

include ('dbconnect.php');

$addmatch = $_GET['addmatch'];

if(!isset($addmatch))
{
$sql = mysql_query("SELECT * FROM matches WHERE winner='tba' AND allowed='1'");

print "<div align='center'><font face='tahoma' size='2'>";
print "<form action=matches.php?addmatch=1 method='POST'>";
while($ab = mysql_fetch_array($sql))
{
print "<input type='radio' name='".$ab['id']."' value='".$ab['team1']."'>".$ab['team1'];
print " - ";
print "<input type='radio' name='".$ab['id']."' value='draw'>draw";
print " - ";
print "<input type='radio' name='".$ab['id']."' value='".$ab['team2']."'>".$ab['team2']."<br><br>";
}
print "<input type='submit' value='bet'>";
print "</form>";
exit();
}
else
{
echo '<hr><br><pre>';
print_r($_POST);
echo '</pre>';
}

?>

basically, the radio buttons are generated using a while statement using all the matches from the db.
Thats the reason why i dont know how to access them, because i the values are taken from a table.

Any ideas what to do.

You could use something like this:

foreach ($_POST as $key => $value) {
    if (is_numeric($key)) {
        echo "$key => $value<br>";
    }
}

Another way to do it would be to number them sequentially, and have a hidden field to store the database ID:

$index = 0;
foreach ($database_results as $row) {
    echo "<input type='radio' name='radio_$index'>";
    echo "<input type='hidden' name='id_$index' value='".$row['id'].">";
    $index++;
}

Keep in mind that with either of these approaches, there is nothing preventing the user from specifying some other ID and altering records they aren't supposed to.
