How to create a custom WordPress shortcode

To create a custom WordPress shortcode, you need to define a custom function that generates the desired output and then register that function as a shortcode using the add_shortcode() function. You can add this code to your theme’s functions.php file or a custom plugin file.

Here’s an example of creating a simple shortcode:

  1. In your WordPress admin dashboard, go to “Appearance” > “Theme Editor.”
  2. In the right sidebar, locate and click on the “functions.php” file.
  3. Add the following code snippet at the end of the file:
// Your custom shortcode function
function my_custom_shortcode($atts) {
    // Extract the shortcode attributes (if any)
    $atts = shortcode_atts(array(
        'text' => 'Hello, world!', // Default value for the 'text' attribute
    ), $atts, 'my_shortcode');

    // Generate and return the output
    return '
' . esc_html($atts['text']) . '
'; } // Register the shortcode add_shortcode('my_shortcode', 'my_custom_shortcode');

This code snippet creates a function called my_custom_shortcode() that generates a div element containing the text specified by the text attribute.

The shortcode_atts() function is used to extract the attributes and provide default values.

The add_shortcode() function registers the shortcode with the tag my_shortcode.

  1. Click “Update File” to save the changes.

Now you can use the [my_shortcode] shortcode in your WordPress posts and pages.

You can also pass the text attribute to customize the output, like this:

[my_shortcode text="Custom text"]

This will display a div element with the specified custom text instead of the default “Hello, world!”.

Note: When creating more advanced shortcodes, make sure to sanitize and validate any user-supplied data to ensure security and proper functionality.
