How to Create Your Own WordPress Shortcodes (Without and With Attribute)

WordPress does not allow us to add PHP code to pages, posts or any custom post types. However, we can create custom functions which are executed when a shortcode is encountered within the post text.

Simple shortcodes:-

Shortcode functions can be added to theme's functions.php file.

Here's a simple “Hello World” example:

add_shortcode('hello_world', 'my_shortcode_func');

function my_shortcode_func() {

return '<p>Hello World!</p>';

}

Enter [hello_world] in the required position in a page or post to output the result ( i.e. Hello World!).

Shortcodes with Parameters:- 

The below shortcode function output image with custom width and height (i.e. you can specify width and height in shortcode)).

add_shortcode( 'dynamic_image', 'my_dynamic_image_func' );

function my_dynamic_image_func( $atts = '' ) {

    $attributes = shortcode_atts( array(

        'width' => 500,

        'height' => 300,

    ), $atts );

    return '<img src="https://via.placeholder.com/'. $attributes['width'] . 'x'. $attributes['height'] . '" />';

}

Enter [dynamic_image width="700" height="500"] shortcode somewhere within a page or post to output the image.
