Parameters

• $titles: 1-dimensional array of strings, representing template titles
• &$templateData: array map (contains key-value pairs) passed by reference, which can be modified by extensions to send their own template data

Use cases

Currently, TemplateData uses this extension. TemplateData will add each template title to the $templateData map, and will assign one of the following values:

• If a title is invalid title or is an invalid redirect title, gives a null value
• If a title doesn't exist, will assign it a 'missing' key assigned with true
• If a title has invalid data from the database, or does not have a 'templatedata' property in the page_props table, assign it as: (object)[ "notemplatedata" => true ]

Notes

• This hook currently lives inside the PHP Parsoid service.
• This hook was originally named "ParsoidFetchTemplateData" in Gerrit change 494817, and renamed to "ParserFetchTemplateData" in Gerrit change 552666.
