Hi.
This shouldnt be a problem to solve for experienced php codes, which I am not. I will welcome help and guidence.
The Thing:
I am subclassing SelectionGroup.php with MyFunc.php ...
In SelectionGroup.php is a function FieldSet() ...
I want to add one line of code into it, but left all the stuff doing its work.. the line I want to add is $item->addExtraClass('selected');
all relevant code also on pastie: http://pastie.org/1182475
function FieldSet() {
$items = parent::FieldSet()->toArray();
$count = 0;
$firstSelected = $checked ="";
foreach($items as $key => $item) {
if(strpos($key,'//') !== false) {
list($key,$title) = explode('//', $key,2);
} else {
$title = $key;
}
if($this->value == $key) {
$firstSelected = " class=\"selected\"";
$checked = " checked=\"checked\"";
}
$itemID = $this->ID() . '_' . (++$count);
$extra = array(
"RadioButton" => "<input class=\"selector\" type=\"radio\" id=\"$itemID\" name=\"$this->name\" value=\"$key\"$checked />",
"RadioLabel" => "<label for=\"$itemID\">$title</label>",
"Selected" => $firstSelected,
);
if(is_object($item)) $newItems[] = $item->customise($extra);
else $newItems[] = new ArrayData($extra);
$firstSelected = $checked ="";
}
return new DataObjectSet($newItems);
}
/// I want to edit section
if($this->value == $key) {
$firstSelected = " class=\"selected\"";
$checked = " checked=\"checked\"";
}
// adding my line
if($this->value == $key) {
$firstSelected = " class=\"selected\"";
$checked = " checked=\"checked\"";
$item->addExtraClass('selected');
}
the class is added on the right place when I edit the core file SelectionGroup.php.
But when I copy the function to MyFunc.php, my label and other code disapear, as it will be working with other set of data.
So if anyone can drop the code of the FieldSet() that should be in MyFunc.php for it to work same as in SelectionGroup.php. that would be awesome..
Even better would be if you can also enlighten me what is going behind the scenes, and why it wont work, and / or point me to a solution for checking the selected radio button in the __constructor of MyFunc.php
Thank you all in advance.
Daniel.
