Wordpress ACF get_field( ) not returning value

Question

I am using the advanced custom field plugin for Wordpress . I am having difficulty displaying a field on my page.

Basically I've created a field group and assigned id's to the members of that group. I then use the get_field('field_name') function to store the value of this field in a variable and echo it on the screen. However this is returning false .

I've also tried using the_field('field_name') but this returns null . I then read somewhere If you are trying to access a field outside of the Wordpress loop you must pass the post id as a parameter to the get_field()/the_field() methods.

I've tried that and still the same result...Does anyone have any idea as to what is the problem?

This is my code:

<?php get_header();
      $postID = get_the_ID();
      the_field('the-title', $postID); //Nothing being returned...
      die(); 
?>

Answer 1

If you're using WP_Query() before using get_field() , you need to reset the query using wp_reset_query() function. I hope it'll solve this issue.

Answer 2

You're using get_the_ID() outside of the loop.

http://codex.wordpress.org/Function_Reference/get_the_ID

You could try:

global $post;
the_field( 'the-title', $post->ID );

But this would depend on what page you're on.

Which template file is this being used in?

Answer 3

You need to create a loop, then inside that loop you can retrieve the data.

<?php while( have_posts() ) : the_post() ?>
     <?php $variable = the_field('the-title'); ?>
<?php endwhile; ?>

I had this issue. This was the format of function:

function get_field( $selector, $post_id = false, $format_value = true ) {
  // ...
}

and I used it like this:

get_field( 'event_date', false, false) {
  // ...
}

ACF has one more function

get_fields([$post_id], [$format_value]);

which returns a value of provided ID. but if we provide only id then by default it considers as post id

but if you provided an ID that is not an id of a post but user, term category, comment, and options tables ID then you have to prefix it like this:

// Get values from the current post.
$fields = get_fields();

// Get values from post ID = 1.
$post_fields = get_fields( 1 );

// Get values from user ID = 2.
$user_fields = get_fields( 'user_2' );

// Get values from category ID = 3.
$term_fields = get_fields( 'term_3' );

// taxonomy name.
$term_fields = get_fields( 'category_3' );

// Get values from comment ID = 4.
$comment_fields = get_fields( 'comment_4' );

// Get values from ACF Options page.
$option_fields = get_fields( 'options' );

// using 'option'.
$option_fields = get_fields( 'option' );

as described in the official docs

I found this when I have to work on a project where I need the value of category term id. this is worked for me outside of the loop.
