check for Checkbox values in template
26 April 2010 at 3:09pm Last edited: 26 April 2010 3:10pm
Hi, I have a checkbox field going into the database:
new CheckboxSetField("CropUse", "Crop Use",array("silage" => "Silage","grain" => "Grain","dual" => "Dual Purpose")),
so, the value in the field will be "grain" or "grain,dual" or "grain,silage,dual" etc...How do I test for the inclusion of a value in this field in the template? Ie I want to do something like:
<% if CropUse = grain %>
<h4>Grain CRM: $GrainCRM</h4>
<% end_if %><% if CropUse = silage %>
<h4>Silage CRM: $SilageCRM</h4>
<% end_if %><% if CropUse = dual %>
<h4>Grain CRM: $GrainCRM / Silage CRM: $SilageCRM</h4>
<% end_if %>something like that....what I want is to be able to test whether one of the 3 values exist in the db field.
thanks in advance! -

I've got the same problem
Of course I could divide it into a set of seperate checkboxes, each saved into a Boolean, but this method looks so much better on the backend.
Is there an efficient way that the controller could separate (explode?) them into different names?

This is some code I wrote for your case. The first part is plain, non-SS php to demonstrate that this logic works.
Second part is an example application of the logic in SS. You will most likely need to tweak it for your particular case.<?php
$data = "dual,silage";
$d = explode(",", $data);
foreach($d as $key) {
if($key == 'silage') {
$silage = true;
}
if($key == 'grain') {
$grain = true;
}
if($key == 'dual') {
$dual = true;
}
}if($dual) { echo "dual "; }
if($silage) { echo "silage "; }
if($grain) { echo "grain "; }// Convert into SilverStripe compatible function
function index() {
$d = explode(",", $this->CropUse);
foreach($d as $key) {
if($key == 'silage') {
$silage = true;
}
if($key == 'grain') {
$grain = true;
}
if($key == 'dual') {
$dual = true;
}
}
return $this->customise(array(
'Silage' => $silage,
'Grain' => $grain,
'DualPurpose' => $dual
));
}?>
With that, you can do this in the template:
<% if Silage %>
<h4>Put something here</h4>
<% end_if %>Let me know if that works.
