Uses:

• Bootstrap 4 to create the grid columns
• Flexbox to create the perfect responsibe squares that contain content
• Wordpress plugin: Advanced Custom Fields to create a repeater field. The repeater field creates a pair of squares (an image square, and a text square). The repeater field contains sub fields for the various elements of the content (background image, heading, text, link etc)

Use the following snippet to display the URL of a custom post types taxonomy term. Just replace the word position with the name of the taxonomy.

<?php
$terms = wp_get_post_terms($post->ID, 'position');
foreach ($terms as $term) {
    echo get_term_link($term);
}
?>

To display the results of a Toolset Types checkbox field, use the following in your PHP template:

$checkbox_value = types_render_field( "my_checkbox_field", array( "separator" => ", " ) );
echo $checkbox_value;

Taking it a step further, we can create conditionals based on values collected. In the following example I have four values:

$blacktown = types_render_field( "localities", array( "option" => "0" ) );
$carlingford = types_render_field( "localities", array( "option" => "1" ) );
$emerton = types_render_field( "localities", array( "option" => "2" ) );
$penrith = types_render_field( "localities", array( "option" => "3" ) );

if ($blacktown) {
    // do something
};
if ($carlingford) {
    // do something
};
if ($emerton) {
    // do something
};
if ($penrith) {
    // do something
};

1. Open a plain text editor like notepad
2. Paste this line there: 
   Header set X-Robots-Tag "noindex"
3. Save as .htaccess (yes, there is no "file name" and after the dot, the htaccess part seems to be the extension)
4. Place it into the wp-includes directory on your server.

Here's a handy conditional snippet to target specific archive or single pages from a custom post type.

Recently I needed a wordpress plugin that allowed me to import a CSV file and store the data into a SQL table. Not knowing any particular plugins I decided to to download, install and test a whole bunch of them - and the results, whilst not always providing a solution to my original problem where still very interesting.

I've recently needed to modify the wordpress menu code so that I could insert bootstrap classes directly into it.

Add the following to the functions file:

// custom menu example @ https://digwp.com/2011/11/html-formatting-custom-menus/
function clean_custom_menus() {
	$menu_name = 'nav-primary'; // specify custom menu slug
	if (($locations = get_nav_menu_locations()) && isset($locations[$menu_name])) {
		$menu = wp_get_nav_menu_object($locations[$menu_name]);
		$menu_items = wp_get_nav_menu_items($menu->term_id);

		$menu_list = '<nav>' ."\n";
		$menu_list .= "\t\t\t\t". '<ul>' ."\n";
		foreach ((array) $menu_items as $key => $menu_item) {
			$title = $menu_item->title;
			$url = $menu_item->url;
			$menu_list .= "\t\t\t\t\t". '<li><a href="'. $url .'">'. $title .'</a></li>' ."\n";
		}
		$menu_list .= "\t\t\t\t". '</ul>' ."\n";
		$menu_list .= "\t\t\t". '</nav>' ."\n";
	} else {
		// $menu_list = '<!-- no list defined -->';
	}
	echo $menu_list;
}

Make sure to replace the menu slug. To do this make sure the menu is assigned to a location on Wordpress. The menu slug is infact the location using lowercase and dashes (for example: footer-menu).

It might be necessary to create a new menu potion in the functions file using the following: 

function register_my_menu() {
   register_nav_menu('journal',__( 'journal' ));
}
add_action( 'init', 'register_my_menu' );

To display the menu, insert the following into the theme:

<?php if (function_exists(clean_custom_menus())) clean_custom_menus(); ?>

The following solutions pertain to the excellent wordpress plug Advanced Custom Fields.

To display fields outside of teh wordpress posts loop use the following code but replace the post ID 123:

$value = get_field( "text_field", 123 );
echo $value;

More info here - and here's how to do it inside the loop.

What about repeater fields?

I'm glad you asked. Here's a PHP snippet to echo the values for a repeating field that I've called logo (just remember to change the ID 1862 to match the post or page ID):

while( have_rows('repeater', 1862) ): the_row();
   the_sub_field('logo');
endwhile;

Output individual fields contained with a group field

Advanced Custom Fields allows the grouping of fileds into a single group field. The following will output individual sub fields (remember to replace the post ID):

$group_field = get_field( "my_group_field", 5563 );
 echo $group_field['my_sub_field'];

This is a super handy snippet that will display a specific pages content. It's very usefull to display content in a module or widget area outside of the main content area.
