ACF PHP Fields - PHP

Introduction

Advanced Custom Fields (ACF) is a popular WordPress plugin that makes it easy to create custom fields for posts, pages, and other WordPress content types. ACF PHP Fields is an add-on for ACF that provides a way to create custom fields programmatically, using PHP code.

With ACF PHP Fields, you can create, modify, and delete ACF fields using PHP code, rather than using the ACF user interface. This can be useful for automating the process of creating fields, or for creating fields programmatically based on certain conditions.

Requirements

To use ACF PHP Fields, you'll need:

• ACF version 5 or later
• PHP version 5.4 or later

Getting Started

To get started with ACF PHP Fields, you'll need to install the plugin and include the necessary files in your WordPress theme or plugin.

Installation

To install ACF PHP Fields, you can either download the plugin from the WordPress plugin repository, or install it using Composer.

To install using Composer, add the following line to your composer.json file:

"require": {
    "wpscholar/acf-php-fields": "*"
}

Then run composer install to install the plugin.

Initialization

After installing the plugin, you'll need to include the necessary files in your WordPress theme or plugin. You can do this using the following code:

require_once WP_PLUGIN_DIR . '/acf-php-fields/loader.php';

Creating Fields

To create fields with ACF PHP Fields, you'll use the acf_field() function. This function takes an array of arguments that define the properties of the field.

Here's an example of code that creates a text field:

acf_field( array(
    'type'        => 'text',
    'name'        => 'my_custom_field',
    'label'       => 'My Custom Field',
    'instructions'=> 'Enter some text',
    'required'    => 1,
    'maxlength'   => 100,
) );

Modifying Fields

To modify an existing field, you'll use the acf_update_field() function. This function takes the ID of the field you want to update, as well as an array of new values for the field.

Here's an example of code that modifies an existing text field:

acf_update_field( 123, array(
    'label'       => 'New Label',
    'instructions'=> 'New Instructions',
) );

Deleting Fields

To delete a field, you'll use the acf_delete_field() function. This function takes the ID of the field you want to delete.

Here's an example of code that deletes an existing field:

acf_delete_field( 123 );

Conclusion

ACF PHP Fields is a powerful tool that makes it easy to create and manage custom fields in WordPress using PHP code. By using ACF PHP Fields, you can streamline your workflow and automate the process of creating fields, saving time and effort.
