RE: [PHP] getting values from multiple select
-Original Message- From: Scott St. John [mailto:[EMAIL PROTECTED]] Sent: 13 March 2002 21:32 I am working on a javascript box that will allow the user to drag values from one select box to another. I will use this box to set the values. This is a standard, multiple select box. On the next page I need to figure out what PHP is doing with the data coming in. If I send 5 fields to the next page PHP will show me one when I echo the variable to the page. Name your field with trailing brackets (e.g. INPUT NAME=field_name[] ...) and you will see it as an array in PHP containing your 5 (or however many) values. Cheers!

Did you try putting brackets at the end of the input names? This tells PHP to put the values into an array, whose key is the name of the input. select name=choice[] multiple=yes option value=aA/option option value=bB/option option value=cC/option /select This might work for you, Erik Erik Price Web Developer Temp Media Lab, H.H.

Re: [PHP] getting values from multiple select
Yes, I have tried that. To view them on the next page I would call them as $choice[0];$choice[1];, etc, but only the first item in the list is available. -Scott On Thu, 14 Mar 2002, Erik Price wrote: Did you try putting brackets at the end of the input names?

Hm... have you tried using a loop to get their values, rather than using
the numeric indexes? Like this:
foreach ($choice as $array_element) {
echo $array_element;
}
This will go through the entire array, regardless of numeric index, and
echo the value of each element in the array. Try this, if it doesn't
work then perhaps only one value is being passed to the receiving script.
Have you made sure your listbox features the attribute
multiple=yes
and have you made sure to select more than one item in the listbox by
holding down either Alt (PC) or Cmd (Mac) as you make your selections.
If you're only selecting ONE item, then only one item will be passed to
the receiving script.
Use the above techniques to make sure that you are actually passing more
than one value.

Re: [PHP] getting values from multiple select
Ok, how about a code snipet since I seem to be blind this morning. The
select box code:
select multiple=yes name=groups id=av
?
$sql = select groupID,groupName from groups order by groupName;
$result = mssql_query($sql,$connection);
while($row = mssql_fetch_array($result)){
$groupID = $row[groupID];
$groupName = $row[groupName];
echo option value=\$groupID\$groupName/option;
}
?
/select
On the next page I tried the code Erik recommended doing this:
foreach ($groups as $group_list){
echo $group_list;
}
Any eye openers? Thanks,
-Scott

Erik- I don't do coffee, but the Iced Tea works just as well :) Thank you, all is well and my happy face is back on. I was missing the [], I had tried that before but had an error because I forgot to update my javascript code.
