Hi Elliot,
I want to give the user the option to choose between having a big thumbnail and a smaller thumbnail.
So I created a select field with two options:
big : big
small : small
In my functions I added two sizes:
if ( function_exists( 'add_image_size' ) ) {
add_image_size( 'big', 550, 9999 );
add_image_size( 'small', 300, 9999 );
}
In my code I want the the_post_thumbnail to use the select value as the size.
$size = get_field('image_size');
if ( has_post_thumbnail() ) {
the_post_thumbnail( '$size' );
}
I’m not certain if this is the correct way of doing this, it makes sense in my head but I don’t have much knowledge of php. My page.php code is below.
<?php
$args = array(
'post_type' => 'post'
);
$size = get_field('image_size');
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
<li>
<?php
if ( has_post_thumbnail() ) {
the_post_thumbnail( '$size' );
}
?>
</li>
<?php endforeach;
wp_reset_postdata();?>
Hi @stevenharris
Close, but change:
the_post_thumbnail( '$size' );
to
the_post_thumbnail( $size );
Please be aware, that you have placed the $size = get_field('image_size');
OUTSIDE of your $myposts loop, so this value is not coming from the post itself, but from what ever the template file is querying.
Thanks
E
