TextformatterProcessImages by Robin S

A Textformatter that processes <img> tags within rich text content.

Process Images

A basic, proof-of-concept Textformatter module for ProcessWire. When the Textformatter is applied to a rich text field it uses Simple HTML DOM to find <img> tags in the field value and passes each img node through a hookable TextformatterProcessImages::processImg() method.

This is a very simple module that doesn't have any configurable settings and doesn't do anything to the field value unless you hook the TextformatterProcessImages::processImg() method.

Hook example

When added to /site/ready.php the hook below will replace any Pageimages in a rich text field with a 250px square variation and wrap the <img> tag in a link to the original full-size image.

For help with Simple HTML DOM refer to its documentation.

$wire->addHookAfter('TextformatterProcessImages::processImg', function(HookEvent $event) {

    // The Simple HTML DOM node for the <img> tag
    /** @var \simple_html_dom_node $img */
    $img = $event->arguments(0);
    // The Pageimage in the <img> src, if any (will be null for external images)
    /** @var Pageimage $pageimage */
    $pageimage = $event->arguments(1);
    // The Page object in case you need it
    /** @var Page $page */
    $page = $event->arguments(2);
    // The Field object in case you need it
    /** @var Field $field */
    $field = $event->arguments(3);

    // Only for images that have a src corresponding to a PW Pageimage
    if($pageimage) {
        // Set the src to a 250x250 variation
        $img->src = $pageimage->size(250,250)->url;
        // Wrap the img in a lightbox link to the original
        $img->outertext = "<a class='lightboxclass' href='{$pageimage->url}'>{$img->outertext}</a>";

“The end client and designer love the ease at which they can update the website. Training beyond how to log in wasn’t even necessary since ProcessWire’s default interface is straightforward.” —Jonathan Lahijani
