Display Filters with Magic Tags

Used to modify the output of your fields using built-in or custom functions, especially helpful for conditional formatting or for complicated display rules.

Overview

Sometimes you need to change the output of the field value depending on where you’re displaying it in your theme. Maybe you need a different date format in different locations, or you want to apply some very specific conditional formatting that is beyond the capabilities of the limited Magic Tags and Template Tags available to the Pods Templating engine. That’s when you can use WordPress functions or your own PHP functions against the contents of the field output.

Quick Start

  1. Create a function stored in your functions.php or an external plugin file. The function should take one parameter and return one value or string.
  2. Inside your Pods Templates, call that function against one of your fields with the syntax {@custom_field,my_function}

Using Functions On Field Output

You can pass the output of any field through any available function with the form {@field_name,any_function}. For example, to sanitize the output from a field for href links or the attributes within them, you may do {@field_name,esc_attr} or {@field_name,esc_html} or {@field_name,esc_url}.

Special Functions for Audio & Video and white-listed oEmbed Providers

Audio & Video

For situations where you’d use the or shortcode in WordPress, we’ve created two special functions pods_audio for Audio and pods_video for video.

ie, {@audio_field_url,pods_audio} or {@video_field_url,pods_video}

oEmbed Providers

For external media files via white-listed oEmbed providers, ie YouTube, Vimeo, etc, it’s better to do:
{@audio_field,wp_oembed_get} and {@video_field,wp_oembed_get} in templates or use wp_oembed_get() directly in PHP. Good reference on that here:

You can also directly use an oEmbed Field.
