如何将if(is_page())用于WooCommerce产品



我在functions.php中使用了一个代码,该代码允许用户发送可定制产品的徽标。我只想将此功能用于此页面,因为其他产品是不可自定义的。一开始我试了一下:

if(is_page('1089')){
\function here
}

然而,每当我使用this或is_post等时,图像输入按钮都会从两个产品中完全消失。你能帮我做这件事吗?我使用的功能是:

add_action( 'woocommerce_before_add_to_cart_button', 'display_additional_product_fields', 9 );
function display_additional_product_fields(){
?>
<p class="form-row validate-required" id="image" >
<label for="file_field"><?php echo __("Logonuzu Yukleyin") . ' '; ?>
<br>
<input type='file' name='image' accept='image/*'>
</br>
</label>
</p>
<br>
<p>Ya da</p>
</br>
<?php
}
}
}
// Add custom fields data as the cart item custom data
add_filter( 'woocommerce_add_cart_item_data', 'add_custom_fields_data_as_custom_cart_item_data', 10, 2 );
function add_custom_fields_data_as_custom_cart_item_data( $cart_item, $product_id ){
if( isset($_FILES['image']) && ! empty($_FILES['image']) ) {
$upload   = wp_upload_bits( $_FILES['image']['name'], null, file_get_contents( $_FILES['image']['tmp_name'] ) );
$filetype  = wp_check_filetype( basename( $upload['file'] ), null );
$upload_dir = wp_upload_dir();
$upl_base_url = is_ssl() ? str_replace('http://', 'https://', $upload_dir['baseurl']) : $upload_dir['baseurl'];
$base_name  = basename( $upload['file'] );
$cart_item['file_upload'] = array(
'guid'   => $upl_base_url .'/'. _wp_relative_upload_path( $upload['file'] ), // Url
'file_type' => $filetype['type'], // File type
'file_name' => $base_name, // File name
'title'  => ucfirst( preg_replace('/.[^.]+$/', '', $base_name ) ), // Title
);
$cart_item['unique_key'] = md5( microtime().rand() ); // Avoid merging items
}
return $cart_item;
}
/*
// Display custom cart item data in cart (optional)
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );
function display_custom_item_data( $cart_item_data, $cart_item ) {
if ( isset( $cart_item['file_upload']['title'] ) ){
$cart_item_data[] = array(
'name' => __( 'Image uploaded', 'woocommerce' ),
'value' => str_pad($cart_item['file_upload']['title'], 16, 'X', STR_PAD_LEFT) . '…',
);
}
return $cart_item_data;
}
*/
// Save Image data as order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );
function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {
if ( isset( $values['file_upload'] ) ){
$item->update_meta_data( '_img_file', $values['file_upload'] );
}
}
// Admin orders: Display a linked button + the link of the image file
add_action( 'woocommerce_after_order_itemmeta', 'backend_image_link_after_order_itemmeta', 10, 3 );
function backend_image_link_after_order_itemmeta( $item_id, $item, $product ) {
// Only in backend for order line items (avoiding errors)
if( is_admin() && $item->is_type('line_item') && $file_data = $item->get_meta( '_img_file' ) ){
echo '<p><a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Open Image") . '</a></p>'; // Optional
echo '<p><code>'.$file_data['guid'].'</code></p>'; // Optional
}
}
// Admin new order email: Display a linked button + the link of the image file
add_action( 'woocommerce_email_after_order_table', 'wc_email_new_order_custom_meta_data', 10, 4);
function wc_email_new_order_custom_meta_data( $order, $sent_to_admin, $plain_text, $email ){
// On "new order" email notifications
if ( 'new_order' === $email->id ) {
foreach ($order->get_items() as $item ) {
if ( $file_data = $item->get_meta( '_img_file' ) ) {
echo '<p>
<a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Download Image") . '</a><br>
<pre><code style="font-size:12px; background-color:#eee; padding:5px;">'.$file_data['guid'].'</code></pre>
</p><br>';
}
}

您可以检查产品id,如下所示:

if(get_the_id() == 1089){
//Your logic here
}

然而,我建议你用不同的方式来做这件事,比如为这些产品创建一个专用类别,这样你就可以稍后添加更多的产品来具有相同的功能,而且如果你删除了该产品并创建了一个新的产品,你不需要再次触摸代码来添加id,只需将产品分配到专用类别即可。然后你的情况会是:

if(has_term('special_category_slug', 'product_cat', get_the_id())){
//Your logic here
}
