Re: [PHP] Getting POSTed values from dynamically named checkboxes

Dillon, John wrote:

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>
                  <td>Whatever</td>
                  <td><input type="checkbox" name="altid36"  value="1"
</td>
                  <td class=textset22><input size="10" type=textfield
value="" name="altprice36"></td>
</tr><tr>
                  <td>Something else</td>
                  <td><input type="checkbox" name="altid37"  value="1"
</td>
                  <td><input size="10" type=textfield value=""
name="altprice37"></td>
</tr><tr> 
//-->

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]
}
