Fix issue #1: howto personalize description for a specific page ?

[pamtbaau]

The fix for issue #1: howto personalize description for a specific page ? applies the following test to check if a page contains frontmatter for description:

if(!isset($page_header->metadata->description)) {
    $meta['description']['name']      = 'description';
    $meta['description']['content']   = $this->desc;
}

Hower, the value of $page_header->metadata is an array and therefor, !isset($page_header->metadata->description) will always be true. Hence the user-defined frontmatter 'metadata:description' will still be ignored.

The test should be !isset($page_header->metadata['description']
