[PHP] Getting POSTed values from dynamically named checkboxes
My problem relates to IF statement in the following code. There are two
checkboxes, named altid$thisid, so for instance they become altid36 and
altid37. When the form is submitted with both checked, I can read the first
altid36, but the second does not pass the IF test. Any suggestions re
possible reasons?
$checkedalts = array();
$x=0;
$y=1;
$array_id = explode(,, $_POST[idlist]);
foreach($array_id as $thisid){
if(${altid . $thisid} == 1){
//OR if(ISSET($_POST[${altid . $thisid}])){
$checkedalts[$x] = $thisid;
$checkedalts[$y] = ${altprice . $thisid};
$x=$x+2;
$y=$x+1;
}
}
The HTML before submission is (without the !--):
!--
tr
tdWhatever/td
tdinput type=checkbox name=altid36 value=1
/td
td class=textset22input size=10 type=textfield
value= name=altprice36/td
/trtr
tdSomething else/td
tdinput type=checkbox name=altid37 value=1
/td
tdinput size=10 type=textfield value=
name=altprice37/td
/trtr
//--

Not what you're looking for, but... are you sure you're doing this the
easiest way?
Try putting your values in an array instead, e.g.
altid[36] and altprice[36]
Then access through:
foreach ($_POST['altid'] as $id = $value)
{
$price = $_POST['altprice'][$id]
}

David
