Object Oriented Form - Multiple Check Boxes using show_element($name, $title)

[bradkenyon]

I am trying to display multiple check boxes for a volunteer form I am putting together. Basically, it asks the user what areas you want to volunteer in, allowing the user select more than one check box.

 

I was successful in doing that with a select option drop down box, only because it was storing the different selections within an array.

 

I imagine I would have to store the different checkboxes within an array, I researched this and noticed I had to use show_element and I still can't piece it together.

 

Thanks!

on the one page have your checkboxes all named the same ie.

do while (whatever) {

  echo "<input type=check value=$var name=\"chkActivity[]\">";

}

 

 

now on your request page put in:

 

$activities = $_POST['chkActivity']

 

all the selected boxes will return their values in an array.

below is copy of code i used for the t shirt selection:

 

////// T-Shirt Size //////
function DF_xfield4 ($v)
{
$flabels = array (array('label'=>'Small','value'=>'Small'),
                   array('label'=>'Medium','value'=>'Medium'),
                   array('label'=>'Large','value'=>'Large'),
                   array('label'=>'X-Large','value'=>'X-Large'),
                   array('label'=>'2X-Large','value'=>'2X-Large'),
                   array('label'=>'3X-Large','value'=>'3X-Large'));

	return array("type"=>"select",
		 "name"=>"D_xfield4",
		 "options"=>$flabels,
		 "size"=>1,
		 "extrahtml"=>$xtra2,
		 "value"=>'$v');
}

 

i want to be able to do the same thing, but i know i can't with modifying this code, for using it for checkboxes, i know the code below won't do the trick, but figured i'd show you, so you could see what i was doing wrong:

 

///// Areas of Interest /////
function DF_xfield1 ($v)
{
$flabels = array (array('name'=>'Childrens Area','value'=>'Childrens Area'),
                   array('name'=>'Retail Sales','value'=>'Retail Sales'),
                   array('name'=>'Info Booth','value'=>'Info Booth'),
                   array('name'=>'Beer/Wine Pouring','value'=>'Beer/Wine Pouring'),
                   array('name'=>'Ticket Takers','value'=>'Ticket Takers'),
                   array('name'=>'Hospitality','value'=>'Hospitality'));

	return array("type"=>"checkbox",
		 		"name"=>"D_xfield1",
		 		//"name"=>$flabels,
		 		"extrahtml"=>$xtra2,
		 		"value"=>'$v');
}

 

this is the of_checkbox.inc file that is on the server, i am not familiar with ooh forms, i was just thrown into it, so i'm trying to figure this checkbox out, and i'm golden:
