This is not the way which you have clled for ACF.
Parameters
<?php $field = get_field($field_name, $post_id, $format_value); ?>
- $field_name: the name of the field to be retrieved. eg “page_content” (required)
- $post_id: Specific post ID where your value was entered. Defaults to current post ID (not required). This can also be options / taxonomies / users / etc
- $format_value: whether or not to format the value loaded from the db. Defaults to true (not required).
Usage
Get a value from the current post
$value = get_field( "text_field" );
Get a value from a specific post
$value = get_field( "text_field", 123 );
Check if value exists
$value = get_field( "text_field" );
if( $value ) {
echo $value;
} else {
echo 'empty';
}
Get a value from other places
$post_id = null; // current post
$post_id = 1;
$post_id = "option";
$post_id = "options"; // same as above
$post_id = "category_2"; // target a specific category
$post_id = "event_3"; // target a specific taxonomy (this tax is called "event")
$post_id = "user_1"; // target a specific user (user id = 1)
$value = get_field( "text_field", $post_id );
Get a value without formatting
In this example, the field image is an image field which would normally return an Image object.
However, by passing false as a 3rd parameter to the get_field function, the value is never formatted and returned as is from the Database.
Please note the second parameter is set to false to target the current post
$image = get_field('image', false, false);
