Hi
I am trying to display an Image Slider which fetches featured image and excerpt from any pages or posts that have a custom field checked to true.
I’ve tried this code here: http://www.advancedcustomfields.com/resources/true-false/ with no luck.
My custom field is a checkbox, that when clicked should add the page or post to the Image Slider. My field name is: ‘display_in_carousel’
How do I modify the code in the example linked above to meet my requirements?
Many Thanks
try something like this:
<ul class="slider">
<?php if( get_field('display_in_carousel') )
{
$image = get_field('image');
if( !empty($image) ): ?>
<li><img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" /></li>
<?php endif;
}
else
{
//do nothing
}
?>
</ul>
of course you need to wrap that like your slider need it (and probably change way of load image too)
or you do it with meta-query like the other part of the example
Hi
Sorry; that’s not the bit i’m stuck on.
It’s the actual meta_query loop that doesn’t appear to be working. I’m just wondering if my ‘value’ & ‘compare’ values are correct?
/*
* Query posts for a true/false value.
* This method uses the meta_query param to match the string “1” to the database value “1|0”
*/
$posts = get_posts(array(
'meta_query' => array(
array(
'key' => 'field_name',
'value' => '1',
'compare' => '=='
)
)
));
if( $posts )
{
foreach( $posts as $post )
{
setup_postdata( $post );
// ...
}
wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly
}
What should my value and compare values be?
Thanks
as far as i understand the array should be:
array(
'key' => 'display_in_carousel',
'value' => '1',
'compare' => '='
)
because true/false should have value 1/0, compare should maybe = instead of == (i am not sure, try out both and one should work)
i dont work long time with wordpress, that’s why i am not that familiar with meta_query
I ended up using this which worked:
<?php
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'page',
'meta_key' => 'display_in_carousel',
'meta_value' => '1'
));
if( $posts ): ?>
<?php foreach( $posts as $post ):
setup_postdata( $post )
?>
<?php endforeach; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
