The ACF acf/load_field filter allows you to modify the fields before they are loaded and displayed in the ACF interface. However, sometimes you may encounter a situation where the acf/load_field filter is not modifying the fields as expected. Here’s a code snippet that demonstrates how to use the acf/load_field filter correctly to modify ACF fields:
function wpsnippets_modify_acf_field($field) {
// Modify the $field object as needed
$field['label'] = 'Modified Label';
$field['instructions'] = 'Modified Instructions';
return $field;
}
add_filter('acf/load_field', 'wpsnippets_modify_acf_field');
In this code snippet, we define a custom function wpsnippets_modify_acf_field that accepts the $field object as a parameter. Inside the function, we can modify the properties of the $field object as needed. In this example, we are modifying the label and instructions properties.
Finally, we use the add_filter function to hook our custom function wpsnippets_modify_acf_field to the acf/load_field filter. This ensures that our function is called whenever ACF loads and displays a field.
By using this code snippet, you can easily modify ACF fields using the acf/load_field filter.
Examples
Example #1: Modifying ACF fields using the acf/load_field filter
This example demonstrates how to modify Advanced Custom Fields (ACF) fields using the acf/load_field filter. The acf/load_field filter allows you to modify the field settings before they are loaded and displayed in the ACF interface.
function wpsnippets_modify_acf_field( $field ) {
// Modify the field settings here
$field['label'] = 'Modified Label';
$field['required'] = 1;
return $field;
}
add_filter( 'acf/load_field', 'wpsnippets_modify_acf_field' );
In this code example, we define a custom function wpsnippets_modify_acf_field that accepts the $field parameter. Inside the function, we can modify the field settings as needed. In this case, we are changing the label of the field to “Modified Label” and setting it as required. Finally, we return the modified field.
Example #2: Modifying ACF fields based on field type
This example demonstrates how to modify ACF fields based on their field type using the acf/load_field filter. By checking the field type, you can apply specific modifications to different types of fields.
function wpsnippets_modify_acf_field( $field ) {
if ( $field['type'] === 'text' ) {
// Modify text field settings here
$field['maxlength'] = 100;
} elseif ( $field['type'] === 'select' ) {
// Modify select field settings here
$field['choices'] = array(
'option1' => 'Option 1',
'option2' => 'Option 2',
);
}
return $field;
}
add_filter( 'acf/load_field', 'wpsnippets_modify_acf_field' );
In this code example, we use conditional statements to check the field type ($field['type']) and apply specific modifications based on the type. For a text field, we set the maximum length to 100 characters. For a select field, we modify the choices to include “Option 1” and “Option 2”.
Example #3: Modifying ACF fields based on field name
This example demonstrates how to modify ACF fields based on their field name using the acf/load_field filter. By checking the field name, you can apply specific modifications to different fields.
function wpsnippets_modify_acf_field( $field ) {
if ( $field['name'] === 'my_field' ) {
// Modify specific field settings here
$field['label'] = 'Modified Field Label';
} elseif ( $field['name'] === 'another_field' ) {
// Modify another specific field settings here
$field['required'] = 1;
}
return $field;
}
add_filter( 'acf/load_field', 'wpsnippets_modify_acf_field' );
In this code example, we use conditional statements to check the field name ($field['name']) and apply specific modifications based on the name. For a field with the name “myfield”, we change the label to “Modified Field Label”. For a field with the name “anotherfield”, we set it as required.
