I tried install FAQ module in SS 2.3.1.
I installed MultiSelectField v.0.2 and installed Faqs V0.5.
But I get error when I create 'Faq Page' in Admin. 'Faqs Holder' is OK.

Error as follow;

ERROR [Warning]: Invalid argument supplied for foreach()

I faced the same problem!!!

MultiSelectField module is installed.

Please help!

I installed latest stable faqs and multiselectfield modules from (Extensions/Module zone) and latest SS (2.3.3) and is working, at least i have no error,

I can create faqs pages, but the Faqs Holder is empty - shouldn't Faqs Holder show the faqs like a the blog module ?

THX

I cannot reproduce the error with Silverstripe v2.3.3. I'll check previous version. Regarding FaqsHolder question: It should show a list of children pages. Without sidebar and without a theme the page list stay at left of the holder page. I'll make a theme sample for faqs module.

I just try the Silverstripe v2.3.0 and faqs Module works. If the errors still occurs please let me know the installed modules. Tested on Apache/2.2.11 (Ubuntu) PHP/5.2.6-3ubuntu4.2 with Suhosin-Patch

I can confirm the problem. It seems, that the syntax for the multiselectfield has changed. There is not changelog for the multiselectfield module, but the README states a change.

I have faqsmodule 0.5.0 and multiselectfield 0.2

Changing the addfieldtotab to the following seems to fix the problem.

// -- Related Faqs
$source = DataObject::get('FaqsPage');
    $fields->addFieldToTab(
        "Root.Content.Related",
        new MultiSelectField(
		"FaqsRelated", // Relationship
		"Related Faqs", // Field name
		$source->toDropdownMap('ID','Title') // Source records (array)
	)
);

But the multiselectfield does not look like the screenshot here -> (http://silverstripe.org/multiselectfield-module/). It only has the left box and you can select and deselect RelatedFaqs using ctrl-key.

yes, is working, first time i deleted by mistake the

return $fields;
	}

so, here is the complete code, Change in FaqsPage.php (under code in faqs module)
this

        // -- Related Faqs
        $fields->addFieldToTab("Root.Content.Related", new MultiSelectField(
        "FaqsRelated", _t("FaqsPageEntry.RELATEDLABEL", 'Related'), "FaqsPage", "ID", "Title"));
        return $fields;
	}

with this

// -- Related Faqs
$source = DataObject::get('FaqsPage');
$fields->addFieldToTab("Root.Content.Related",new MultiSelectField(
      "FaqsRelated", "Related Faqs", $source->toDropdownMap('ID','Title') )
);
return $fields;
	}

Hi,

I have this working now after the mod posted by OnebyOne, however, I have one small problem in that I can select one FAQPage for related FAQ and all saves fine. If I try to select more than one, after the save there none remain.

Cheers
David
