I am using WP_Query for visitor to filter the posts. The posts is about products. So in the filter, it has a field where user can select Maximum price and Minimum price. (Just like most of the shopping site).
Okay this is the filter form that I use to collect the user input:
<lable>Min. Price ($)</lable>
<select name="minprice">
<option value="0">0</option>
<option value="100">100</option>
<option value="200">200</option>
<option value="300">300</option>
.....
</select>
<lable>Max. Price ($)</lable>
<select name="maxprice">
<option value="100">100</option>
<option value="200">200</option>
<option value="300">300</option>
<option value="400">400</option>
.......
</select>
And this is the function that handle the inputs :
function filter_search() {
$max = $GET_['maxprice'];
$min = $GET_['minprice'];
$args = array(
'post_type' => 'product',
'meta_query' => array(
array(
'key' => 'price',
'value' => array( $min, $max ), //this is the line where i cant figure out how.
'compare' => 'BETWEEN'
)
)
);
$searched_posts = new WP_Query( $args);
return $searched_posts;
}
Am I correct to use the array for the value that I wish to compare?

This looks right, I have very similar code that works as expected:
function price_query_test() {
update_post_meta( 7, '_price', 10 );
update_post_meta( 12, '_price', 20 );
update_post_meta( 18, '_price', 30 );
update_post_meta( 72, '_price', 40 );
$test = new WP_Query( array(
'post_type' => 'page',
'meta_query' => array( array(
'key' => '_price',
'value' => array( '10', '25' ),
'compare' => 'BETWEEN',
) ),
'fields' => 'ids',
) );
printf( '<pre>%s</pre>', print_r( $test->posts, 1 ) );
die();
}
add_action( 'init', 'price_query_test' );
The above gives me an array:
Array
(
[0] => 12
[1] => 7
)
If we wanted to we could also add in our meta_query
a type:
'meta_query' => array( array(
'key' => '_price',
'value' => array( '10', '25' ),
'compare' => 'BETWEEN',
'type' => 'NUMERIC',
) )
But it seems to work as expected without the meta_type
.
If you’re using WooCommerce, do note that their metavalue is _price
and not price
.
