Hi,

i’m using following script to fetch the first image of a repeater:

<? query_posts('cat=4'.'&showposts=4&posts_per_page=4'); 	// latest blog story?>
    <?php while (have_posts()) : the_post(); ?>

<?php
$main_field = get_field('beelden');
$first_img = $main_field[0]['beelden']['url'];
?>

<a href="<?php the_permalink() ?>"><img src="<?php echo $first_img ?>"/></a>

	<?php endwhile; ?>

recently, i’ve been getting this error:

Fatal error: Cannot use string offset as an array in /home/pxlwemg122/domains/manufracture.be/public_html/wp-content/themes/sandbox/category-blog.php on line 40

any ideas? this has worked perfectly (and still does on a other website!) in the past.

thanks
Mathieu

I think your issue is that you have a repeater field with the name of “beelden” but also seem to have a subfield within that repeater with the same name?

Hi @mathieu

In case you are using a repeater, I would recommend that you use a the standard repeater loop to access the repeater rows.

<?php

// check if the repeater field has rows of data
if( have_rows('repeater_field_name') ):

 	// loop through the rows of data
    while ( have_rows('repeater_field_name') ) : the_row();

        // display a sub field value
        the_sub_field('sub_field_name');

    endwhile;

else :

    // no rows found

endif;

?>

If you just want the first row, you can introduce custom code to only pick the first row.

I hope this helps.
