Escaping output with only specific allowed HTML elements

Sometimes when developing for WordPress, you will want to echo something. As all good developers know, any such content must be escaped. This makes sure that nothing nasty can be echoed and keeps you code more secure.

WordPress comes with a number of escaping functions, however sometimes they don't quite do as you want. Take this example.

wpmark

<?php
/**
 * Register some default block editor styles for this block.
 */
function hd_register_block_styles() {

	// add the small image style.
	register_block_style(
		'core/heading', // name of your block
		array(

wpmark

<?php
/**
 * Registers the Facets with FacetWP.
 *
 * @param array  $facets The current array of registered facets.
 * @return array $facets The modified array of registered facets.
 */
function hd_utility_add_job_facets( $facets ) {

	// add the job industry facet.

wpmark

<?php
/**
 * Registers any additional settings required for the plugin.
 */

/**
 * Registers the setting for the placeholder attachment ID.
 */
function hd_utility_register_image_placeholder_id_setting() {

wpmark

<?php
/**
 * Used to filter email from 'address'
 */
function hd_email_send_wp_mail_address( $input ) {
	
	// return a new from email address.
	return 'no-reply@highrise.digital';

}

wpmark

// set alignment options for cover, video, and paragraph blocks.
wp.hooks.addFilter(
    'blocks.registerBlockType',
    'hd-theme/hd-theme',
    function( settings, name ) {
        if ( name === 'core/cover' || name === 'core/video' || name === 'core/paragraph' || name === 'core/list' ) {
            return lodash.assign( {}, settings, {
                supports: lodash.assign( {}, settings.supports, {
                    // allow support for full and wide alignment.
                    align: ['full', 'wide'],

Caching WordPress data using Transients - Example

In this simple example we create a function for obtaining data from an external source and caching it for 24 hours. You can use the function hd_get_external_data() to get the data and work with it in your site.

If you want to force a refresh of the cache, you can pass a value of true into the function.

You can place the code into your themes functions.php file or better still in a plugin. If you are placing it in a plugin, remember to use function_exists() when using this. This ensures that the code will fail correctly if the plugin is not active.
