Woocommerce自定义产品文本 [英] Woocommerce Custom Product Text

问题描述

我正在尝试使用woocommerce创建可变产品，该产品将包括特定于每种产品的用户输入文本。为此，我正在检测 custom_text类型并显示文本输入字段，而不是正常的选择选项下拉列表。

I'm trying to create a variable product using woocommerce which will include user input text which is specific to each product. To do so I am detecting for 'custom_text' type and displaying a text input field instead of the normal select-option dropdown.

这在variable.php中：

This is in variable.php:

<form action="<?php echo esc_url( $product->add_to_cart_url() ); ?>" class="variations_form cart" method="post" enctype='multipart/form-data' data-product_id="<?php echo $post->ID; ?>">

    <?php 
    $loop = 0; foreach ( $attributes as $name => $options ) : $loop++; 

        <?php  if(is_array($options) && $options[0] == "custom_text") : //Name to be added to product ?> 
            <label for="<?php echo sanitize_title($name); ?>"><?php echo $woocommerce->attribute_label($name); ?></label></td>
            <input type="text" class="fullwidth req" id="<?php echo esc_attr( sanitize_title($name) ); ?>" name="attribute_<?php echo sanitize_title($name); ?>"/>
        <?php else : ?>
    ...

当您得到例外时，此方法有效到购物车页面时，将输入显示为所有小写字母，并删除了空格（更改为连字符）等。

This is working except when you get to the cart page it is showing the input as all lower case with white spaces removed (changed to hyphens) etc.

有人知道您可以在哪里挂入和/或覆盖此行为？我一直在尝试一切都无济于事。

Does anyone know where you could hook in and/or override this behavior? I have been trying everything to no avail.

谢谢

推荐答案

            // Get value from post data
            // Don't use woocommerce_clean as it destroys sanitized characters
            $value = sanitize_title( trim( stripslashes( $_REQUEST[ $taxonomy ] ) ) );

上一个位于woocommerce-functions.php中的339行。
需要更改为：

The previous is located on line 339 in woocommerce-functions.php. It needs to be changed to:

 $value = trim( stripslashes( $_REQUEST[ $taxonomy ] ) ) 

现在只需要适当地覆盖此文件即可。我从woocommerce-functions.php复制了原始函数，并将其添加到主题的functions.php中。然后，我对其进行了更改，以免影响用户输入。

Now it's just a matter of overriding this file properly. I copied the original function from the woocommerce-functions.php and added it to my theme's functions.php. I then changed it so that it does not sanitize the user input.

这是我添加到主题功能中的内容。php：

This is what I added to my theme's functions.php:

add_action( 'init', 'override_add_to_cart_action' );
function override_add_to_cart_action( $url = false ) { // Original function is woocommerce_add_to_cart_action()
     // ... full function above and below
     $value = trim( stripslashes( $_REQUEST[ $taxonomy ] ) );
     // ...
}

通过这种方式我们可以无需更改任何核心文件，使我们可以在需要时更新插件。 ：）

By doing it this way we do not have to change any core files allowing us to update the plugin when needed. :)
