hi,
With acf5, i think there is a bug with creating a WP archive with custom field filter.
I created exactly the same custom fields (bedrooms), pasted exactly the same code on page and function which are eplained on your documentation : http://www.advancedcustomfields.com/resources/tutorials/creating-wp-archive-custom-field-filter/
It return on frontend :
Notice: Undefined index: bedrooms
on my page i have (exactly the same as on the documentation page):
$field = get_field_object('bedrooms');
Warning: Invalid argument supplied for foreach()
the foreach loop is (exactly the same as on the documentation page):
foreach( $field['choices'] as $choice_value => $choice_label ):
the entire code :
page-something.php
<?php
$field = get_field_object('bedrooms');
$values = explode(',', $_GET['bedrooms']);
?>
<ul>
<?php foreach( $field['choices'] as $choice_value => $choice_label ): ?>
<li>
<input type="checkbox" value="<?php echo $choice_value; ?>" <?php if( in_array($choice_value, $values) ): ?>checked="checked"<?php endif; ?> /> <?php echo $choice_label; ?></li>
</li>
<?php endforeach; ?>
</ul>
functions.php
add_action('pre_get_posts', 'my_pre_get_posts');
function my_pre_get_posts( $query )
{
// validate
if( is_admin() )
{
return;
}
if( !$query->is_main_query() )
{
return;
}
// get original meta query
$meta_query = $query->get('meta_query');
// allow the url to alter the query
// eg: http://www.website.com/events?location=melbourne
// eg: http://www.website.com/events?location=sydney
if( !empty($_GET['bedrooms']) )
{
$bedrooms = explode(',', $_GET['bedrooms']);
//Add our meta query to the original meta queries
$meta_query[] = array(
'key' => 'bedrooms',
'value' => $bedrooms,
'compare' => 'IN',
);
}
// update the meta query args
$query->set('meta_query', $meta_query);
// always return
return;
}
Is the documentation page out of date?
Thank you
