Hi There,
Awesome plugin again!!

I was hoping you could guide me in the right direction.

My client has about 500 authors on a blog and asked if I could add an extra field on their bio to input the city.

It’s worked great and I am able to display it on all of my posts.

Is there a way to use Search Filter pro to search by this Custom Field?

Thank you so much again for building this.

Note,
Added the custom field in my theme using this:

add_action ( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action ( 'edit_user_profile', 'my_show_extra_profile_fields' );

function my_show_extra_profile_fields ( $user )
{
?>
    <h3>Extra profile information</h3>
    <table class="form-table">
        <tr>
            <th><label for="city">City</label></th>
            <td>
                <input type="text" name="city" id="city" value="<?php echo esc_attr( get_the_author_meta( 'city', $user->ID ) ); ?>" class="regular-text" /><br />
                <span class="description">Please enter your City.</span>
            </td>
        </tr>
    </table>
<?php
}

add_action ( 'personal_options_update', 'my_save_extra_profile_fields' );
add_action ( 'edit_user_profile_update', 'my_save_extra_profile_fields' );

function my_save_extra_profile_fields( $user_id )
{
    if ( !current_user_can( 'edit_user', $user_id ) )
        return false;
    /* Copy and paste this line for additional fields. Make sure to change 'city' to the field ID. */
    update_user_meta( $user_id, 'city', $_POST['city'] );
}

And call it in posts like this:

<?php echo get_the_author_meta( 'city', $coauthor->ID ); ?>
