Header Footer Code Manager [hfcm] Shortcode

The ‘hfcm’ shortcode from the Header-Footer-Code-Manager plugin is designed to retrieve and display specific scripts. It uses the ‘id’ attribute to identify the desired script from the database. The function checks the device type and excludes scripts not suitable for the current device. If the script is active and valid for the device, it’s rendered on the page.

Shortcode: [hfcm]

Parameters

Here is a list of all possible hfcm shortcode parameters and attributes:

• id – The unique identifier of the specific script to be displayed

Examples and Usage

Basic example – A simple usage of the hfcm shortcode to display a script with a specific ID on your WordPress site.

[hfcm id=1 /]

Advanced examples

Using the hfcm shortcode to display a script with a specific ID, and also specify the device type. This example will display the script only on desktop devices. If the specified ID is not found, the shortcode will not render anything.

[hfcm id=1 device_type='desktop' /]

Another advanced usage of the hfcm shortcode, this time to display a script with a specific ID, but only on mobile devices. If the specified ID is not found, the shortcode will not render anything.

[hfcm id=1 device_type='mobile' /]

Please note that the ‘device_type’ parameter is not explicitly supported by the hfcm shortcode function, but it’s used here for illustrative purposes. In real usage, you would need to modify the hfcm_shortcode function to support this parameter.
