如何获取functions.php中的当前页面id表单

I need to be able to test which page is currently being displayed from within functions.php. This is so that I can apply a different filter to my posts based on which page is being displayed.

For example I have two pages one called buy.php and the other sold.php. I need to be able to target some kind of unique id for each of these pages when they are currently displayed and then use a if statement to apply different filters.

How I want my code to work;

if(page = buy.php){
    $posts['meta_query'][] = array(
        'key'       => 'property_status',
        'value'     => 'For Sale'
    );
}else if(page = sold.php){
    $posts['meta_query'][] = array(
        'key'       => 'property_status',
        'value'     => 'Sold'
    );
}

How can I do this?

I need to the code to work within this function, which is filtering my posts;

add_action('wp_ajax_customfilter', 'property_filter');
add_action('wp_ajax_nopriv_customfilter', 'property_filter');

function property_filter(){
    $posts = array(
        'posts_per_page'    =>  -1,
        'post_type'         =>  'property',
        'orderby'           =>  'date'
    );

    $posts['meta_query'] = array( 'relation' => 'AND' );

    // price filtering

    if($_POST['min_price'] && !empty($_POST['min_price'])){
        $min_price = $_POST['min_price'];
    }else{
        $min_price = 0;
    }

    if($_POST['max_price'] && !empty($_POST['max_price'])){
        $max_price = $_POST['max_price'];
    }else{
        $max_price = 10000000;
    }

    $posts['meta_query'][] = array(
        'key'       => 'property_price',
        'type'      => 'NUMERIC',
        'value'     => array($min_price, $max_price),
        'compare'   => 'BETWEEN'
    );

    // bed filtering

    if($_POST['min_beds'] && !empty($_POST['min_beds'])){
        $min_beds = $_POST['min_beds'];
    }else{
        $min_beds = '1'; 
    }

    if($_POST['max_beds'] && !empty($_POST['max_beds'])){
        $max_beds = $_POST['max_beds'];
    }else{
        $max_beds = '9+'; 
    }

    $posts['meta_query'][] = array(
        'key'       => 'bedrooms',
        'value'     => array($min_beds, $max_beds),
        'compare'   => 'BETWEEN'
    );

    //location filtering

    if(isset( $_POST['location'] ) && $_POST['location']){
        $location = $_POST['location'];
        $location_val = stripslashes($location);

        $posts['meta_query'][] = array(
            'relation'  => 'OR',

                'compare'   => 'LIKE'
            ),

            array(
                'key'       => 'town',
                'value'     => $location_val,
                'compare'   => 'LIKE'
            ),

            array(
                'key'       => 'county',
                'value'     => $location_val,
                'compare'   => 'LIKE'
            ),

            array(
                'key'       => 'postcode',
                'value'     => $location_val,
                'compare'   => 'LIKE'
            )
        );                          
    }

    // property type filtering
    if(isset( $_POST['type'] ) && $_POST['type']){
        $posts['meta_query'][] = array(
            'key'       => 'type_of_property',
            'value'     => $_POST['type'],
            'compare'   => 'IN'
        );
    }

    // secondary flash filtering
    if(isset( $_POST['flash_type'] ) && $_POST['flash_type']){
        $posts['meta_query'][] = array(
            'key'       => 'optional_category',
