pagelist enquiry

I understand this older add-on field type may be unsupported, but I'm currently trying to return the details for a parent page to use as a breadcrumb. The standard navigation system will not suffice as the user is picking a limited number of specific pages to be used as cameo links on the home page.

I can obtain the ID of the parent page using small modification to pagelist, but I'm lost trying to work out the rest:

$parent = $Page->pageParentID();

            if (is_object($Page)) {
                $store['pagePath'] = $Page->pagePath();
                $store['pageTitle'] = $Page->pageTitle();
                $store['pageNavText'] = $Page->pageNavText();
                $store['id'] = $Page->id();
                $store['pageSortPath'] = $Page->pageSortPath();
                $store['pageThumb'] = $Page->pageThumb();
                $store['colour'] = $Page->colour();
                $store['description'] = $Page->description();
                $store['pageParentID'] = 'ID: '.$parent;

                $store['_default'] = $Page->pagePath();
            }

Is it possible to obtain the pageNavText and pagePath of the parent from the parent ID and have it available to a pagelist content type?

Yes, you could use:

$Pages = new PerchContent_Pages;
$ParentPage = $Pages->find($parent);

Thanks Drew, I'll take a look.

Hello Drew,

I've modified the code as follows:

$Pages = new PerchContent_Pages();
            $Page = $Pages->find($this->raw_item);

            $ParentPage = $Pages->find($parent);

            if (is_object($Page)) {
                $store['pagePath'] = $Page->pagePath();
                $store['pageTitle'] = $Page->pageTitle();
                $store['pageNavText'] = $Page->pageNavText();
                $store['id'] = $Page->id();
                $store['pageSortPath'] = $Page->pageSortPath();
                $store['pageThumb'] = $Page->pageThumb();               
                $store['_default'] = $Page->pagePath();


                $store['ParentpageNavText'] = $ParentPage->pageNavText();

            }
        }
        return $store;
    }

    public function get_processed($raw=false)
    {    
        if (is_array($raw) && isset($raw['pagePath'])) { 
            if ($this->Tag->output()) {
                if (isset($raw[$this->Tag->output()])) {
                    return $raw[$this->Tag->output()];
                }
            }
            return $raw['pagePath'];
        }

        return $raw;
    }

However when trying to save I get the error message:

Call to a member function pageNavText()

It refers to the line:

$store['ParentpageNavText'] = $ParentPage->pageNavText();

Any pointers would be appreciated.

Where is $parent defined?

Just seen a potential fix, I'll give it a go and come back shortly...

Go there eventually... I needed the extra if statement for generating the parents values into the $store

Full working script:

 * Examples:
 *
 * <perch:content id="page" type="pagelist" label="Page" /> (output="path" by default)
 * <perch:content id="page" type="pagelist" label="Page" output="title" />
 * <perch:content id="page" type="pagelist" label="Page" output="navtext" />
