Dear Sir/Madam,

I have a custom field in single line type, I try to query all fields without content

    $args = array (
    		'posts_per_page' => -1,
        'post_type'  => 'member',
        'post_status' => 'publish',
        'meta_query' => array(
            array(
                'key' => 'wpcf-uprise-payment-source-id',
                'value' => '',
                'compare' => '='
            )
        )
    );

but no result until I click into the post and publish without any change. Please advise how I can make the query args ?

Hello,

For those existed posts, which don't have custom field meta values, you need to use "NOT EXISTS" operator, please try to modify your custom codes as below:

$args = array (
    'posts_per_page' => -1,
    'post_type'  => 'member',
    'post_status' => 'publish',
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'wpcf-uprise-payment-source-id',
            'value' => '',
            'compare' => '='
        ),
        array(
            'key' => 'wpcf-uprise-payment-source-id',
            'compare' => 'NOT EXISTS'
        )
    )
);

And test again
