When retrieving and displaying custom fields in WordPress plugins like Advanced Custom Fields, developers should follow best practices to ensure security and efficiency. It is important to sanitize and validate user input to prevent SQL injection and cross-site scripting attacks. Additionally, developers should use WordPress functions like `get_field()` to retrieve custom field values and `esc_html()` to escape output to prevent malicious code execution.
// Retrieve and display custom field value using Advanced Custom Fields
$field_value = get_field('custom_field_name');
echo esc_html($field_value);
