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.

Import CSV files

Download: https://en-au.wordpress.org/plugins/import-csv-files/

A very simple plugin that efficiently imports data from a CSV file and matches it against a variety of post/page related fields. I can see that this plugin would be extremely helpfull for creating pages or posts from a spreadsheet of data. I can already forsee a potential use for this plugin in an upcoming project where I need to migrate much content from static HTML website into a wordpress site.

ImportWP

Another great content importer that matches the CSV data to a variety of wordpess fields. This plugin is very simple to use, and has a number of advanced features in the free version such as the ability to not only map the content to a wordpress post or page, but also a user, taxonomy, or custom post type. The premium version of this plugin allows automated scheduled importing.

An additional JavaScript library adds features like sorting, pagination, filtering, and more for site visitors. Tables can be imported and exported from/to Excel, CSV, HTML, and JSON files.

WP CSV to DB

WP CSV to Database plugin allows you to insert CSV file content into WordPress database. You can selectively insert data into a particular database table. You can also export any WordPress database table content to a CSV file using this plugin. Useful when you want to bulk upload data from your CSV file (example: product details) to the WordPress database in one go. Bulk data import from CSV (Microsoft Excel) file. Bulk data export from your database to CSV file

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.

The following is a snippet of code I used to display a widget with the ID video title after the widget (rather than before the widget).

<?php $sidebar_id = 'video';
$sidebars_widgets = wp_get_sidebars_widgets();
$widget_ids = $sidebars_widgets[$sidebar_id];
foreach( $widget_ids as $id ) {
   $wdgtvar = 'widget_'._get_widget_id_base( $id );
   $idvar = _get_widget_id_base( $id );
   $instance = get_option( $wdgtvar );
   $idbs = str_replace( $idvar.'-', '', $id );
} ?>

<section id="video">
   <div class="inner">
      <div class="container">
         <?php dynamic_sidebar( 'video' ); ?>
         <?php echo $instance[$idbs]['title']; ?>
      </div>
   </div>
</section>

These two functions create anchor links, and you can customize a lot of it, but it's impossible to add a class through just using their parameters alone. Use the themes functions.php file to give these links a classname:

add_filter('next_posts_link_attributes', 'posts_link_attributes');
add_filter('previous_posts_link_attributes', 'posts_link_attributes');

function posts_link_attributes() {
    return 'class="styled-button"';
}

A big thankyou to Evan Herman over at Code Parrots who helped me out with the following solution to an request that I submitted. He has developed a terrific timeline plugin for Wordpress, that is very flexible and looks super jazzy.
