Debbuging WordPress

Add following rows to wp-config.php file:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

It creates and updates debug.log file in the wp-content folder.

Page template and custom header

Few quick heurekas about these topics. Page template

Name your file like this: my-template.php
At the beginning of my-template.php add:
Actually it showed up in both cases Template name: My-template and Template name: my-template. It is traditionally used with capital letter, but I have to check, maybe it is a standard

Different header

Name your file like this: header-yourheadername.php

To call it out on your about page, add into template-file.php or about-template.php:

if(is_page('about')){
    
    get_header('yourheadername');

} else {
    get_header();
}

Show x latest blogposts

Needed a quick solution for displaying five latest blogposts on home-page. It will show only titles and makes them active links. This is the code:


 '5' );
	$recent_posts = wp_get_recent_posts( $args );
	foreach( $recent_posts as $recent ){
		echo '' .   $recent["post_title"].'  ';
	}
	wp_reset_query();
?>

If different number of posts is needed, change the number 5 in this row:

$args = array( 'numberposts' => '5' );

Get the title in default language

Sometimes we need variables to stay in a default language, e.g in English. For example, we have a multi-language site but Google Maps accepts country's name only in English. In our php-part:

if (ICL_LANGUAGE_CODE!="en"){
   $original_ID = icl_object_id( $post->ID, 'post', false, 'en' );
   $country = get_the_title( $original_ID );
   
  } else {
       $country = $country_full_name;
  }

And in our HTML-part:

Change categories’ order

Needed the categories to be in certain order - not in alphabetical and not by id. It can be done by some plugin, but here is the way also through code:

 // change order of terms
   	function gto_forced_order($orderby) {

             switch (ICL_LANGUAGE_CODE){
   	      case("de"):
    	         $orderby = "FIELD(t.term_id, 465, 468,524,525,574,575, 600, 601,1240, 775, 777, 778, 841,843, 844)";
    	      break;
   	      case("fr"):
    	         $orderby = "FIELD(t.term_id,183, 184,203,204, 218, 219, 230, 231, 1239, 294, 296, 297, 306, 308,309)";
    	      break;
   	      case("ru"):
    	        $orderby "FIELD(t.term_id,954,955,974,975,989,990,1041,1042,1241,1145,1147,1375,1184,1186,1187)";
    	      break;
              case("es"):
    	         $orderby = "FIELD(t.term_id,834, 935,994,995,1009,1010,1021,1022,1242, 1165,1167,1168,1177,1179,1180 )";
    	       break;
               case("zh-hant"):
    	           $orderby = "FIELD(t.term_id,464, 467,526,527, 569, 570,609, 610,1238,795, 797, 798, 834, 836, 837)";
    	       break;
               case("ar"):
    	         $orderby = "FIELD(t.term_id,466, 469,528,529, 579, 580,591, 592,1243,815, 817, 818, 827, 829, 830)";
    	       break;
               default: 
     	         $orderby = "FIELD(t.term_id,125,95,97,121,33,32,124,99,37,36,96,122,123,94,34)";
     	        break;
              }

 
         return $orderby;
       }
add_filter('get_terms_orderby','gto_forced_order');

//original query
$tax_terms = get_terms( $tax, $tax_args );
gto_forced_order($tax_terms);

Just change the terms' IDs. Source as usual almighty Internet.

Translating WordPress: Your Own Text Domain for WordPress

For translating your theme we need to define our text domain in functions.php:

And where needed we can do like that:

Or as function:

Translations can be managed by WPML String Translations or .po files. More can be read here.

Echoing Advanced Custom Fields Plugin’s Fields

Wordpress's plugin Advanced Custom Fields gives the opportunity to echo out the field:

But sometimes you need it as a variable, then use get_field('your_field_name'):

If catergory has children, then make a link

term_id, $term->taxonomy );

if (sizeof($term_children)==0){
// if category has no children, we won't make a link
?>
   name; ?>

 } else { 
// if catergory has childre, we ask a link
   $term_link =get_term_link($term);
?>
     
    name ?>

Get term link

$term_link = get_term_link($term);

Is it a subpage of the page id 129?

So in your functions.php file:

**
 * Check whether we are on a subpage
 *
 * @return mixed ID of the parent post or false if this is not a subpage.
 */
function wpdocs_is_subpage() {
    // Load details about this page.
    $post = get_post();
 
    // test to see if the page has a parent
    if ( is_page() && $post->post_parent ) {
        // Return the ID of the parent post.
       return $post->post_parent;
    // There is no parent so ...
    } else {
        // ... The answer to the question is false
          return false;
    }
   
}

And in your page.php or where ever:
