displaying an array in a template
13 December 2010 at 11:21pm
How do you display an array of data in a template? I have some code that works but it seems extreme, is this really what I need to get it to work?
Controller code
function UKCities()
{
$_list = array('Aberdeen
', 'Armagh
', 'Bangor
', 'Bath
', 'Belfast');$list = new DataObjectSet();
foreach($_list as $key => $data) {
$data = array('City' => $data);
$list->push(new ArrayData($data));
}
return $list;
}Template code
<% control UKCities %>
<option>$City</option>
<% end_control %> -

Hi,
In Controller code use:function UKCities() {
$_list = array( 'Aberdeen', 'Armagh', 'Bangor', 'Bath', 'Belfast');$listoption = "Select your City";
foreach($_list as $list) {
$listoption .= "<option value=\"".$list."\">".$list."</option>";
}return $listoption;
}And in Your template between <select></select> paste:
$UKCities
You can also use DropdownField() .

I would agree that DropDownField is the best option, but I'd disagree with writing '<option>' etc in the controller, to get your original version working I'd do the following... (note:untested!)
function UKCities()
{
$_list = array('Aberdeen', 'Armagh', 'Bangor', 'Bath', 'Belfast');$list = new DataObjectSet();
foreach($_list as $data) {
$do=new DataObject();
$do->City = $data;
$list->push($do);
}
return $list;
}Template code
<% control UKCities %>
<option>$City</option>
<% end_control %> -

Thanks guys, I thought there had to be a better way. I agree with swaiba about the HTML seperation and your code worked perfectly with just copy and paste.
