$_POST Help

[jazon]

Ok, I'm having a really tough time getting this to work the way I want.

Page One

[PHP]
<? while ($row = mysql_fetch_array($result)){ ?>

<tr>

<td><input type="text" name="lots[]" size="13" maxlength="12" value=""></td>

<td><input type="checkbox" name="tanks[]" value="<? echo("$row[serial]"); ?>"></td>

</tr>

<? } ?>

[/PHP]


Page Two
[PHP]
<?
$howmany = count($_POST['tanks']);
if ($howmany > 0){
foreach($_POST['tanks'] as $serial => $tank){
//Whatever
}
}
?>
[/PHP]

Yay, page two works fine.

BUT, What I really want to do is Make it so that I can make an SQL query with both the lot and serial on page two.

Such as $query = SELECT * FROM 'whatever' WHERE lot = lots[] and tank = tanks[]

And, I have absolutely no idea how to go about doing this.

Does that make much sense? Please let me know if I need to clarify anything. I'm really confused and very new to this.

The foreach loop is a shorthand convenient format of the for loop. Do not forget what is behind it.

$tanks = $_POST['tanks'];
$lots = $_POST['lots'];

for($c=0;$c<sizeof($lots);$c++){
$lot = $lots[$c];
$lot = $lots[$c];

as $serial => $tank){
//Whatever
}
}
?>

Such as $query = SELECT * FROM 'whatever' WHERE lot = lots[] and tank = tanks[]

Ignore last. False submission

[PHP]$tanks = $_POST['tanks'];
$lots = $_POST['lots'];

for($c=0;$c<sizeof($lots);$c++){

$query = "SELECT * FROM 'whatever'
WHERE lot = $lots[$c] AND tank = $tanks[$c]";
}[/PHP]
You may need curly brackets around the array variables in the SELECT string
