meta for modification date?

[in8sworld]

This is a type: question but not sure how that gets assigned.

I have been using picocms for some time now and love it (thanks to all!) but I've come across a need (want) and can't figure out how to accomplish it. I'm thinking it would need to be a plugin with a function:

I write up my posts and date them using the date meta tag. The posts are ordered by date (I'm using a blog type functionality in a sub-folder) but I occassionally update a post at a later date. What I would like is to keep that posted date unchanged, and have a separate field to display the modified date (if different) of the file. I would prefer that it is the modified date of the file from the underlying OS through some function and not a manually updated date in the Yaml header (which would be simple enough to do). This way I wouldn't have to remember to update the modified date every time and I'm sometimes updating the file a bunch of times subsequent to publishing it.

Thanks again for all the work on this great project!

Try something like this (untested; written for Pico 2.0):

class PicoLastModificationPlugin extends AbstractPicoPlugin
{
    const API_VERSION = 2;

    public function onMetaParsed(array &$meta)
    {
        if (!isset($meta['modificationTime']) && file_exists($this->getRequestFile())) {
            $meta['modificationTime'] = filemtime($this->getRequestFile());
        }
    }

    public function onSinglePageLoaded(array &$pageData)
    {
        if ($pageData['id']) {
            $fileName = $this->getConfig('content_dir') . $pageData['id'] . $this->getConfig('content_ext');
            if (!isset($pageData['modificationTime']) && file_exists($fileName)) {
                $pageData['modificationTime'] = filemtime($fileName);
            }
        }
    }
}

Thanks so much! I was able to get it working in Pico v1 (update 200203: still working in Pico v2) with just the first part of your function (note the added date function to make the date non-Unix time) saving it as the filename PicoLastModificationPlugin.php in the plugins directory and by including {{ meta.modificationTime }} to my blog page twig file. I wasn't sure how I would use the second portion of your function.

class PicoLastModificationPlugin extends AbstractPicoPlugin
{
    const API_VERSION = 2;
    public function onMetaParsed(array &$meta)
    {
        if (!isset($meta['modificationTime']) && file_exists($this->getRequestFile())) {
            $meta['modificationTime'] = date ("F d, Y", filemtime($this->getRequestFile()));
        }
    }
}

I then added an if statement to that twig template so that the modification date line only shows up if I manually set a moddate field in the YAML header. This way I can choose if I want folks to know that I'm editing the post after the fact or not (helpful when I've got a lot of older posts to put up but don't want them all to appear like I edited them recently when all I did was move the files around)

{% if meta.moddate %}
Modified on {{ meta.modificationTime }}
{% else %}
{% endif %}
