Fügen Sie einen mehrsprachigen Text nach Preis in woocommerce_get_price_html hook

Question

Ich baue eine WooCommerce-Website und Customizing, Kopieren und Einfügen von Code aus Internet-Bibliotheken.

Ich habe es geschafft, "benutzerdefinierte Preis und benutzerdefinierten Text" in woocommerce Produkt hinzufügen, so dass sie in verschiedene Sprachen übersetzt werden können. Hier ist der Blick von der Produktseite: https://www.primacent.de/de/product/woo-album-3-2

Hier ist mein Code in functions.php:

//New Price 
add_action('woocommerce_product_options_pricing','custom_unit_price'); 
function custom_unit_price() { 
    woocommerce_wp_text_input(array('id' => '_unit_price', 'class' => 'wc_input_price short', 'label' => __('Unit Price', 'woocommerce') . ' ('.get_woocommerce_currency_symbol().')', 'type' => 'number', 'desc_tip' => 'true','description' => __('Enter the unit price if you want to show this price type.', 'woocommerce'), 'custom_attributes' => array(
        'step' => 'any', 
        'min' => '0' 
       ))); 
} 
add_action('woocommerce_process_product_meta_simple', 'save_custom_unit_price'); 
function save_custom_unit_price($post_id) { 
    global $wpdb, $woocommerce, $woocommerce_errors; 
    update_post_meta($post_id, '_unit_price', stripslashes($_POST['_unit_price'])); 
} 
// Text Field for unit measurement 
add_action('woocommerce_product_options_pricing','custom_unit_measurement'); 
function custom_unit_measurement() { 
woocommerce_wp_text_input (array('id' => '_unit_measurement', 'label' => __('Unit Measurement', 'woocommerce'), 'placeholder' => 'i.e: pro Stück','desc_tip' => 'true','description' => __('Enter the unit measurement in your language. If you want to show price per unit, this field must be filled', 'woocommerce') 
    ) 
); 
} 
add_action('woocommerce_process_product_meta_simple', 'save_custom_unit_measurement'); 
function save_custom_unit_measurement($post_id) { 
    global $wpdb, $woocommerce, $woocommerce_errors; 
    update_post_meta($post_id, '_unit_measurement', stripslashes($_POST['_unit_measurement'])); 
} 

// only copy the opening php tag if needed 
// Change the shop/product prices if a _unit_price is set 
function sv_change_product_html($price_html, $product) { 

    $_unit_price = get_post_meta($product->id, '_unit_price', true); 
    if (! empty($_unit_price)) { 
     $price_html = '<span class="amount">' . wc_price($_unit_price). ' </span>'; 
         echo $_unit_measurement = get_post_meta($product->id, '_unit_measurement', true);echo'<br />';  

    } 

    return $price_html; 
} 

add_filter('woocommerce_get_price_html', 'sv_change_product_html', 10, 2); 

Das Problem ist, dass ich die Einheit Messung (_unit_measurement) nach dem Stückpreis (_unit_price) will, um die Bindestrichmarke '-' zu ersetzen.

Aus einigen Gründen kann ich den zweiten Meta-Wert nicht in <span> wrap.

Bitte helfen Sie mir. Wie kann ich das erreichen?

Danke!

Answer 1

Sie müssen nur diesen Wert in einem String Einheit Messung verketten (in einem <span> Tag zum Beispiel) nach dem Preis .= Operator für $price_html Variable, bevor sie zurückgegeben werden.

So wird Ihr Code sein:

//New Price 
add_action('woocommerce_product_options_pricing' ,'custom_unit_price'); 
function custom_unit_price() { 
    woocommerce_wp_text_input(array( 
     'id'    => '_unit_price', 
     'class'    => 'wc_input_price short', 
     'label'    => __('Unit Price', 'woocommerce') . ' ('.get_woocommerce_currency_symbol().')', 
     'type'    => 'number', 
     'desc_tip'   => 'true', 
     'description'  => __('Enter the unit price if you want to show this price type.', 'woocommerce'), 
     'custom_attributes' => array(
      'step'   => 'any', 
      'min'   => '0' 
     ) 
    )); 
} 

add_action('woocommerce_process_product_meta_simple', 'save_custom_unit_price'); 
function save_custom_unit_price($post_id) { 
    global $wpdb, $woocommerce, $woocommerce_errors; 
    update_post_meta($post_id, '_unit_price', stripslashes($_POST['_unit_price'])); 
} 

// Text Field for unit measurement 
add_action('woocommerce_product_options_pricing','custom_unit_measurement'); 
function custom_unit_measurement() { 
    woocommerce_wp_text_input (array(
     'id'   => '_unit_measurement', 
     'label'   => __('Unit Measurement', 'woocommerce'), 
     'placeholder' => 'i.e: pro Stück', 
     'desc_tip'  => 'true', 
     'description' => __('Enter the unit measurement in your language. If you want to show price per unit, this field must be filled', 'woocommerce') 

    )); 
} 

add_action('woocommerce_process_product_meta_simple', 'save_custom_unit_measurement'); 
function save_custom_unit_measurement($post_id) { 
    global $wpdb, $woocommerce, $woocommerce_errors; 
    update_post_meta($post_id, '_unit_measurement', stripslashes($_POST['_unit_measurement'])); 
} 

// only copy the opening php tag if needed 
// Change the shop/product prices if a _unit_price is set 
add_filter('woocommerce_get_price_html', 'sv_change_product_html', 10, 2); 
function sv_change_product_html($price_html, $product) { 

    $_unit_price = get_post_meta($product->id, '_unit_price', true); 

    if (! empty($_unit_price)) { 
     $_unit_measurement = get_post_meta($product->id, '_unit_measurement', true); 

     // Here you just concatenate the $_unit_measurement variable (in for example another span tag) after the price 
     $price_html = '<span class="amount">' . wc_price($_unit_price). ' </span>'; 
     $price_html .= '<span class="mesurement">' . $_unit_measurement . ' </span><br />';   
    } 
    // return the formated price with the formated unit mesurement 
    return $price_html; 
}
