大概简单的PHP if / else语句不起作用

Question

I seem to be having trouble with another piece of what seems to be super basic PHP, but it just won't work for me.

My client (real estate website) needs to be able to have properties with no price to be either “price upon request” OR “auction”. Currently, leaving the price field blank only allows for one.

I tried changing the following code:

$listing_price_labels = array(
‘sold’ => __( ‘Sold’, ‘wpsight’ ),
‘rented’ => __( ‘Rented’, ‘wpsight’ ),
‘request’ => __( ‘Price on request’, ‘wpsight’ ),
‘auction’ => __( ‘Auction’, ‘wpsight’ ), ***– Added this line***
);

And where this code is found…

if( is_admin() ) 
        $listing_price .= ‘<br />’ . wpsight_get_price_value();

    } elseif( empty( $listing_price ) ) {

        // When no price available Price on request
        $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['request'] . ‘</span><!– .listing-price-on-request –>’;

    } elseif( $listing_price = ‘auction’ ) {

        // When price field contains ‘auction’ (case sensitive)
        $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['auction'] . ‘</span><!– .listing-price-on-request –>’;

    }



    function wpsight_get_price( $post_id = '' ) {

        // Get post ID from $post_id

        if( empty( $post_id ) )
            $post_id = get_the_ID();    

        // If still empty, return false

        if( empty( $post_id ) )
            return false;

        // Set listing price labels

        $listing_price_labels = array(
            'sold'    => __( 'Sold', 'wpsight'  ),
            'rented'  => __( 'Rented', 'wpsight'  ),
            'request' => __( 'Price on request', 'wpsight' ),
            'auction' => __( 'Auction', 'wpsight' ),
            );

        $listing_price_labels = apply_filters( 'wpsight_get_price_labels', $listing_price_labels );

        // Get listing price
        $listing_price = wpsight_get_price_value();

        // Get custom fields

        $custom_fields          = get_post_custom( $post_id );
        $listing_status         = isset( $custom_fields['_price_status'][0] ) ? $custom_fields['_price_status'][0] : false;
        $listing_availability   = isset( $custom_fields['_price_sold_rented'][0] ) ? $custom_fields['_price_sold_rented'][0] : false;

        // Create price output

        if( ! empty( $listing_availability ) ) {

            // When listing is not available

            $sold_rented = ( $listing_status == 'sale' ) ? $listing_price_labels['sold'] : $listing_price_labels['rented'];

            // Display sold/rented bold red in admin
            $style = is_admin() ? ' style="color:red;font-weight:bold"' : false;

            $listing_price = '<span class="listing-price-sold-rented"' . $style . '>' . $sold_rented . '</span><!-- .listing-price-sold-rented -->';

            if( is_admin() ) 
                $listing_price .= '<br />' . wpsight_get_price_value();

        } elseif( empty( $listing_price ) ) {

            // When no price available Price on request
            $listing_price = '<span class="listing-price-on-request">' . $listing_price_labels['request'] . '</span><!-- .listing-price-on-request -->';

        } elseif( $listing_price == "auction" ) {

            // When price field contains 'auction' (case sensitive)
            $listing_price = '<span class="listing-price-on-request">' . $listing_price_labels['auction'] . '</span><!-- .listing-price-on-request -->';

        }

        return apply_filters( 'wpsight_listing_price', $listing_price );

    }

I'm sure my syntax must just be wrong, because with that code in place it makes any property with anything at all written into the price field display “auction”.

Can anyone see what I've done wrong?

Answer 1

try:

if( is_admin() ){
    $listing_price .= ‘<br />’ . wpsight_get_price_value();

    } elseif( empty( $listing_price ) ) {

    // When no price available Price on request
    $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['request'] . ‘</span><!– .listing-price-on-request –>’;
}

btw its not recommended to use if( is_admin() ) since its only applicable on 1 line.
