This plugin provides a set of simple, powerful helper functions to reduce boilerplate code and streamline the process of retrieving and displaying ACF field values in your templates. It includes helpers for getting single values (with support for nested groups), and for easily looping over repeater fields. The plugin is built with security and best practices in mind, ensuring that all output can be properly escaped.

Features:

get_acf(): A versatile function to get any field value. It supports dot notation for nested group fields and automatically handles get_sub_field() context within repeaters.
repeater(): A clean way to loop through repeater fields with callbacks. Includes optional callbacks for before and after the main loop, and allows passing an arguments array to the row callback. (Requires ACF Pro)
get_repeater_field(): Fetch a specific sub-field value from a specific row, or an array of all values for a sub-field across all rows. (Requires ACF Pro)
Lightweight and secure.
Logs to the PHP error log for easy debugging.

Usage Examples:

get_acf()

This is your main function for retrieving any ACF field value.

Basic Usage: Get the value of a text field named page_headline.
Providing a Default Value: If the page_subtitle field might be empty, provide a fallback.
Escaping HTML: When outputting a value inside an HTML attribute, always escape it.
```
";
```

Other escape options: html, url, js, text.

Getting a Value from an Options Page: To get a field value from an ACF Options Page, pass option as the $post_id.



Getting a Value from a Nested Group Field: Use dot notation to access fields inside a group.



Automatic Sub Field Usage: Inside a standard ACF have_rows loop, get_acf() automatically uses get_sub_field() so you don’t have to change your function calls.
' . get_acf('member_name', '', 'html') . '';
    endwhile;
endif;


repeater() (ACF Pro Only)
This function simplifies looping over repeater fields.


Basic Repeater Loop: To display a list of testimonials from a repeater named testimonials with a sub-field testimonial_text:
' . get_acf('testimonial_text', '', 'html') . '';
});



Using Before and After Callbacks: To wrap your repeater output in 
 and  tags.
' . get_acf('service_name') . '
';
    },
    [], // No args needed for this example
    function() { // Before callback
        echo '';
    },
    function() { // After callback
        echo '';
    }
);



Passing Arguments to the Callback: To make your repeater template more reusable, pass in arguments.
 'faq-item',
    'heading_level' => 'h3'
];

repeater(
    'faqs',
    function($index, $args) {
        printf('', esc_attr($args['item_class']));

        printf(
            '<%s>%s',
            esc_attr($args['heading_level']),
            esc_html(get_acf('question')),
            esc_attr($args['heading_level'])
        );

        echo '' . get_acf('answer', '', 'html') . '';
    },
    $args
);  



get_repeater_field() (ACF Pro Only)
Use this to get data from a repeater field without looping through it manually.


Get All Values from a Sub-Field:
Total attendees: ' . count($all_attendees) . '';
