Hello dear Seblod team and fellow Seblod users,
I love the potential Seblod adds to Joomla, but sometimes I have trouble getting things done.
At this moment I'm really struggling to call groupx values in script fields from the Code Pack. I've created a content (item_content_grp) type with 3 fields (field1, field2 and field3) and I've added a groupx field (item_content) in another content type (item) with content type item_content_grp. Now I want the values of field1 and field2 as arrays in a beforeRender field, but I have been struggling to achieve this for many days.
I get either NULL or array(0) {} as result and the following debug results Notice: Uninitialized string offset, Notice: Trying to get property of non-object and Warning: Illegal string offset 'field1'.
I followed the instructions by Lionel here to create the groupx field (field1, field2 and field3 have no storage and groupx has storage custom | article | item[item_content]).
I installed jdump, but so far it didn't help me. I tried creating array this way with the path to the groupx values I found here:
dump($fields['item_content']);<br>
$array1 = array();<br>
$c = count($fields['item_content']) - 1;<br>
for ($i=0; $i<=$c; $i++) {<br>
$array1 = $fields['item_content']->value[$i]['field1']->value<br>
}<br>
var_dump($array1;
What am I missing? Can anyone help me get this right?

Richard
Try dumping $fields first to see what kind of information is there.
Hi Klas,
Thanks for your response. I was not sure how your suggestion would help me. I tried it, but the dump now contained all content item fields. So I decided to look for more information on the web about mixed objects and arrays. For more clarity I renamed the groupx field to groupx1 in the example below.
At the some point I realised that it I needed to point to the form array and loop through its children, which resulted in this:
$array1 = array();
$c = intval($fields['groupx1']->display -1);//correction for extra field shown by default
for ($i = 0; $i < $c; ++$i) {
$array1[] = $fields['groupx1']->form[$i]['field1']->value;
}
Which returned:
array (
[0] => value1
[1] => value2
[2] => value3
)
And that was what I was looking for. So finally I have this problem solved.
Regards,
Richard
The $c needs no correction so it should be just: $c = intval($fields['groupx1']->display;
