You can use the following:
<?php
print '<form method=post action=add.php>
<input type=checkbox name="id[]" value="abc">ABC
<input type=checkbox name="id[]" value="daf">DAF
<input type=checkbox name="id[]" value="zwg">ZWG
<input type=submit value=Submit>
</form>';
?>
This will place all of the values checked into elements of an array named
id.
You may name them using a method similar to what follows:
while (odbc_fetch_into ($sql_result, &$array)) {
$userid = $array[0] . '[]';
$user_name = $array[1];
echo "<input type=checkbox name=$userid value=1>$user_name";
}
To recall the values you can use:
for ($i = 0; $i < count($id); $i++) {
print $id[$i] . "<br>\n";
}
Hope this helps:

Subject: [PHP] [PHP4] Checkboxes and POST
hi,
i was wondering how PHP4 deals with the following:
<?php
echo"
<form method=post action=add.php>
<input type=checkbox name=id value="abc">ABC
<input type=checkbox name=id value="daf">DAF
<input type=checkbox name=id value="zwg">ZWG
<input type=submit value=Submit>
</form>";
?>
if i check all three boxes, i end up getting only "ZWG" in add.php:
<?php
echo "id: $id";
?>
i understand that the easiest way around it is to name each checkbox a
different name. however, my problem is that i have a lot of checkboxes
generated automatically based on the results of a database query:
while (odbc_fetch_into ($sql_result, &$array)) {
$userid = $array[0];
$user_name = $array[1];
echo "<input type=checkbox name=$userid value=1>$user_name";
}
the purpose of this is to let the current user add all the other users
into his "group." but by doing the above, i have no effective way of
finding out all the boxes/userid's that have been checked in the add.php
file because i don't know the $userid's returned by the query...
any suggestoins? comments? ideas?
