get_term_meta() – get value from taxonomy meta field

31.05.2019

This function is used if you need to get some taxonomy meta data. This function works the same as the get_post_meta() function.

get_term_meta ( $term_id, $key, $single )

$term_id
(number) (required) we specify the taxonomy element ID

$key
(string) (optional) we specify the name of the key of the meta field. If the key is not specified, it will display an array of all meta fields of this taxonomy. Default “.

$single
(logical) (optional) can be:

false – returns all values of arbitrary fields with the specified key as an array, this is what I mean:

true – returns the very first value of an arbitrary field with the specified key as a string;

Returns:

if $single is false, then returns an array of values for the specified meta field.
if $single is true, then returns the value of the specified meta field (the very first).

Example of use:

$termini = get_terms( 'category', 'hide_empty=-1' );
 
foreach( $termini as $termin ){
 
echo $termin_meta = get_term_meta( $termin->term_id, 'my_meta_field', true );
 
}

In this example, we passed through the cycle all taxonomies (posts headings) and derived the result for each rubric (category). To get data about taxonomy elements, we used the get_terms() function.

The most important thing! Do not forget to check that your taxonomy has created meta fields, otherwise you will get an empty array. You can add data using simple functions add_term_meta() or update_term_meta().

wp_kses() or how to leave in the text only allowed HTML tags and their attributes

31.05.2019

This feature allows you to filter content and leave there only those HTML tags and their attributes that you want.

wp_kses ( $content, $html_tags, $protocols ) ;

$content
(string) (required) the content that you want to filter is placed here

$html_tags
(array) (required) an array listing the allowed HTML tags and their attributes

array(
    'a' => array(
        'href' => array(),
        'title' => array()
    ),
    'br' => array(),
    'em' => array(),
    'strong' => array(),
    'p' => array(),
    'h2' => array(),
    'img' => array(
        'alt' => array(),
        'src' => array()
    )
)

$protocols
(array) (optional) lists the allowed protocols. For example, the following protocols are allowed by default: http, https, ftp, mailto, news, irc, gopher, nntp, feed and telnet.

Returns the filtered text.

As an example, I’ll show the code that filters the content that is displayed using the get_the_content() function. In this example, it was not possible to use the the_content() function, so we used get_the_content() in conjunction with a filter that is embedded in the the_content() function.

$html_tags = array(
    'a' => array(
        'href' => array(),
        'title' => array()
    ),
    'br' => array(),
    'em' => array(),
    'strong' => array(),
    'p' => array(),
    'h2' => array(),
    'img' => array(
        'alt' => array(),
        'src' => array()
    )
);
 
echo wp_kses(apply_filters( 'the_content', get_the_content() ), $html_tags);

wp_count_posts () or how to count the number of posts in WordPress

30.05.2019

Very convenient and fast function that allows you to get the number of posts of a certain type of records, as well as any status, even unpublished and deleted.

In principle, when working with WP_Query(), you can also get the number of posts according to your request, but do you need to do this in each case, or maybe you want to get the number of posts that have not only published status.

wp_count_posts ( $type, $perm );

$type
(string) (optional) specify the name of the type of records that we want to count. Default: ‘post’.

$perm
(string) (optional) allows you to make so that the user’s personal (private) posts are added to the counting of the number of records. To do this, specify ‘readable’.

Returns an object with the number of posts for each status. Here is an example of what happens:

stdClass Object
	(
   	 	[publish] => 23
		[future] => 0
    		[draft] => 0
	    	[pending] => 0
	    	[private] => 0
    		[trash] => 0
    		[auto-draft] => 0
    		[inherit] => 0
    		[request-pending] => 0
    		[request-confirmed] => 0
    		[request-failed] => 0
    		[request-completed] => 0
	)

The most important thing to keep in mind is that the function returns an object, and not just the number of published posts. Now I will give a simple example of how to display the number of published posts for your custom post type:

$count_posts = wp_count_posts('services'); //specify the type of record you created - services
 
$published_posts = $count_posts->publish; //number of posts published only
 
echo $published_posts; //we derive the received quantity

WordPress Drag & Drop Page Builder Solutions

24.10.2015

Drag and Drop Page Builder is the latest and strongest addition of the WordPress arsenal. It empowers the users to design the layout of the website EXACTLY the way they want… and they don’t have to have any technical, coding or web designing skills.

It is being predicted by many web designers (me included) that in future, maybe four five years from now, we won’t have any clients for frontend development. That is because these web builders will take over our current job. Everyone who wishes to make a website, will be able to make it without the help any coder or designer.

Don’t worry, we won’t lose our jobs, we will go on backend, and many other kinds of jobs will also open up so don’t worry.

Getting back to today’s topic, I wanted to share the paid and free resources that help you install a drag & drop page builder in your WordPress. Whether you are a developer or a common WordPress user, you should find this post highly useful.

Paid Solutions

These days, everyone who is looking for a WordPress website, wants a drag and drop page builder incorporated in the theme. Of course, there are many themes in the market that contain such page builders. A couple of months ago, Chris Lema reviewed some of the themes that include page builders. You can find other similar reviews on the internet as well.

But today, my topic is not the theme you can buy, but rather including a page builder in your own themes. Let’s see what your options are.

I’m starting with the solutions that web developers need. Or maybe those customers who really want a top-notch solution, it doesn’t matter if they have to pay a few dollars.

Visual Composer by WP Bakery

This is undoubtedly the most successful page builders available for WordPress. They also are one of the pioneers of page building technology in WordPress.

Visual Composer brags of having over 50,000 customers. Indeed a startling fact.

They have found so many customers thanks to dozens of content elements, skin builder capability, high class support, object oriented code, multilingual design and many more addons.

Developers love to use it for their high-end themes. If you are a developer who is creating a WordPress theme for a quality conscious client, this is the thing you need. However, if you don’t have any special needs for your website, then this solution maybe a little waste of money. Visual Composer costs $25.

Minimax

This is a relatively new plugin in the market (compared to Visual Composer) but it is making its mark. In my opinion, this plugin is more suitable if you are not a guru when it comes to coding and development.

Minimax focuses more on the frontend and it focuses on visual effects, such as loading bars etc. rather than functionality that developers love.

Nonetheless, Minimax is a very powerful resource when it comes to drag and drop page builders for WordPress. It is so powerful that if I have to buy a plugin, I might buy this one as I haven’t used it before but it is really intriguing me.

Minimax costs $35.

Free Drag and Drop Page Builder Plugins

Time now for the free solutions that enable routine WordPress users to add the power of custom made pages in their WordPress websites.
