Multi-select list boxes.

Stinger51

Never had to tackle this one before. I'm trying to allow the user to make multiple selections in a date list box. The list box displays the numeric days in the month. Pretty simple stuff.

The offical scooty I can find on this is to do something like :

$theDays = $_POST['lboxDay'];
// get the data from the list box named "lboxDay" on the previous form.

$expDays = explode (",", $theDays);

This explodes the post data into an array of all the days selected in the list box, which are supposed to be delimited with a comma (the HTML standard). So, I should then be able to see those days with something like :

echo " Day 0 = $expDays[0]";
echo " Day 1 = $expDays[1]";
echo " Day 2 = $expDays[2]";
.
.
.

Problem is, the array $expDays only contains the last day selected in the list box. 😕

have you specified the multiple selection attribute?
are you using [Ctrl] or [Shift] to actually select more than 1 option? (selected options will be high-lighted)

This should be elementary, no?

I'm just trying to pass an array of list box data (with MULTIPLE set) to the next form via the POST method, and then explode it so I can use it.

The PHP code for building the list box must be :

$ListBox = "<select name = 'lboxDay[]' size = '5' multiple>";

I had to include the array notation [] to get this to work. And, since the list box is returning an array, and not a string, no call to explode() is necessary. The array values can be simply retrieved with :

$theDay = $_POST['lboxDay'];

echo " Day 0 = $theDay[0]";
echo " Day 1 = $theDay[1]";
echo " Day 2 = $theDay[2]";
.
