I have some ACF(advanced Custom Fields) image values that I display in an include file outside of the main loop. The ACF image is stored as an array, so I would like to display the array values, for example URL, alt tag, size , ect..
This is my code
<?php
global $wp_query;
$postid = $wp_query->post->ID;
$callout_image = get_post_meta($postid, 'callout_image', true);
wp_reset_query();
?>
<?php if( !empty( $callout_image ) ): ?>
<img src="<?php echo esc_url($callout_image['url']); ?>" alt="<?php echo esc_attr($callout_image['alt']); ?>" />
<?php endif; ?>
the error is Warning: Illegal string offset ‘url’ in
What am I doing wrong?
This is because you are using get_post_meta(). The value stored in the DB for an image is just the post ID of the image. Using ACF get_field() is required to get the array.
Hello John,
thank you for responding
I did try that and got no results, I just want to point out that this code is running outside the loop. Is there something I need to adjust with that?
$callout_image = get_field('callout_image', $postid);
should do it.
