By default, the card displays the name and title in the overlay. I wonder if I can add the parent (and possibly child) category to the overlay, before the name. Is this straightforward?

@ Brian

This is possible but requires that you edit the card.php file found here:

../wp-content/plugins/connections-gridder/

Add this line of code where you want the categories to be shown:

<?php $entry->getCategoryBlock( array( 'separator' => ', ', 'before' => '<span>', 'after' => '</span>' ) ); ?>

Rather than overwrite the existing card.php file, you should follow the advice in this QuickTip so your change is not lost if the the template is updated.

Thanks for the reply, Steven, but the code is not working; I’m sure I’m not applying it correctly. I’m using the format from demo 1 on this page, with the static overlay. I’d like the subcategory (e.g., category = animal, subcategory = dog) to print above the name, for example line 1: “dog”; line 2: NAME; line 3: title. Therefore, I pasted it on line 43 of card.php, but to no avail. Any suggestions would be appreciated. Thanks.

@ Brian

Line 43 should be the correct line to paste the code on to get it to display above the name. Pasting it on that line you would not need the opening and closing php tags though, just this:

$entry->getCategoryBlock( array( 'separator' => ', ', 'before' => '<span>', 'after' => '</span>' ) );

Id did forget about the CSS you would need… you need to define the size and line height otherwise it will not show.

#cn-gridder .cn_category_label,
#cn-gridder .cn_category {
  line-height: 18px;
  font-size: 16px;
  font-weight: normal;
}

Hope that helps.

That works. Thanks! If you have time for one more related question: I have two types of people, faculty and grad students, and two categories for each, nested under a parent category (e.g., parent: faculty; children: core, affiliate). For faculty, I’m merging the parent with the child minus the separator, yielding “core (child) faculty (parent)”. For grad students, I’d like to only display the parent. I think this will require an if parent === id, print parent, but I’m not sure how to do it. I think this page provides a clue, but if it’s straightforward, and if you have time, I’d appreciate one more bit of help. Thanks.

Yes would need to do something similar to the link you shared but I think I would add it to the card.php file rather than implement a whole new plugin.

Rather than using the $entry->getCategoryBlock() method you have to work with the $entry->getCategory() method. That’ll return the category data rather display it.

Then you would do something like this:

foreach ( $entry->getCategory() as $category ) {
  if ( $category->parent == 2 ){
    array_push( $faculty, $category );
  elseif ( $category->term_id == 11 ) {
    $student = $category;
}

foreach ( $faculty as $person ) {
  echo 'Faculty (' . esc_html( $person->name ) . ')';
}

if ( isset( $student ) ) {
  echo esc_html( $student->name );
}

Hope that get you on your way!
