Question

在WooCommerce中，我想在产品名称中添加几个字符，因此它们与客户端的QB SKU相匹配。

相关产品属于同一产品类别。我希望有一个mySql查询/命令，我可以调整一下这个可怜的伪代码：

表格中的

wp_posts，其中category =＆＃34; a product category＆＃34; PREPEND＆＃34; abc _＆＃34;到产品名称。

任何想法？

感谢。

Answer 1

更新：我不是SQL专家，但它肯定会帮助您了解如何构建完整的SQL查询。

在下面的末尾，你会发现一个你将运行一次的自定义功能，它将完成这项任务。

获取您的产品类别ID ...
在“wp_term_taxonomy”表中检查相应的'term_taxonomy_id'（通常与产品类别ID相同）。

以下是获取此特定类别的产品ID数组的方法：

global $wpdb;

// Define HERE the corresponding 'term_taxonomy_id' of your product category.
$term_taxonomy_id = 11;

$table_name = $wpdb->prefix . "term_relationships";
$product_ids = $wpdb->get_col( "
    SELECT object_id  
    FROM $table_name 
    WHERE `term_taxonomy_id` = $term_taxonomy_id 
    ORDER BY $table_name.object_id ASC
" );

经过测试和工作

使用该代码，您可以创建一个能够实现您想要的功能的功能：

function prepending_products_names(){

    global $wpdb;

    // Define HERE the corresponding 'term_taxonomy_id' of your product category.
    $term_taxonomy_id = 11;

    $table_name = $wpdb->prefix . "term_relationships";
    $product_ids = $wpdb->get_col( "
        SELECT object_id
        FROM $table_name
        WHERE `term_taxonomy_id` = $term_taxonomy_id
        ORDER BY $table_name.object_id ASC
    " );

    foreach( $product_ids as $product_id ){
        // get the post object
        $post_obj = get_post($product_id);
        // get the product sku
        $product_sku = get_post_meta( $product_id, '_sku', true);
        // Customizing the product name
        // (You can prepend the a part of the sku to it)
        $custom_product_name = 'abc_'. $post_obj->post_title;

        // Updating the product name
        wp_update_post( array(
            'id' => $product_id,
            'post_title' => $custom_product_name,
        ) );
    }
}

// Run this one time reloading a backend page and comment it 
// (or remove the code aftewards).

if(is_admin())
    prepending_products_names();

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试并有效。

Answer 2

您希望获得当前的产品类别ID

/// <summary>
/// Deep insert parent and child.
/// </summary>
/// <param name="parentEntityPluralName"></param>
/// <param name="entity"></param>
public TEntity SaveWithChildren<TEntity>(string parentEntityPluralName, TEntity entity) where TEntity : BaseEntityType
{
    // need to serialize the entity so that we can send parent and child together
    string serializedEntity = Newtonsoft.Json.JsonConvert.SerializeObject(entity, new Newtonsoft.Json.JsonSerializerSettings() { ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore });

    // create a handler for the httpclient
    using (System.Net.Http.HttpClientHandler httpHandler = new System.Net.Http.HttpClientHandler())
    {
        // create the httpclient and add the handler
        using (System.Net.Http.HttpClient httpClient = new System.Net.Http.HttpClient(httpHandler))
        {
            // setup the headers
            httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Prefer", @"odata.include-annotations=""*""");
            httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/json;odata.metadata=minimal");

            // setup the content to send
            using (System.Net.Http.StringContent odataContent = new System.Net.Http.StringContent(serializedEntity))
            {
                // setup the content type to json
                odataContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");

                // post the data to the odata service
                using (System.Net.Http.HttpResponseMessage response = httpClient.PostAsync(this.BaseUri + parentEntityPluralName, odataContent).Result)
                {
                    // get back any errors or content
                    string content = response.Content.ReadAsStringAsync().Result;

                    // show error if service failed
                    if (response.IsSuccessStatusCode == false)
                    {
                        throw new Exception(content);
                    }

                    // try to convert the object back from the service call
                    return Newtonsoft.Json.JsonConvert.DeserializeObject<TEntity>(content);
                }
            }
        }
    }
}

然后使用此选项根据产品类别设置值。

<?php 
session_start();

$dbserver = 'localhost';
    $dbname = '########';
    $dbuser = '########';
    $dbpassword = '########';

    $category = $_GET['category'];
    $db = mysqli_connect($dbserver, $dbuser, $dbpassword, $dbname);

    if (mysqli_connect_errno()) {
        die("Connection failed: " . mysqli_connect_error());
    }
    mysqli_select_db($db, $dbname);
    $sql = "SELECT * FROM products WHERE category = '".$category."'";
    $result = mysqli_query($db, $sql);

    if (!$result) {
        die ('Error: Could not select products'.mysqli_error($db));
    } 

   function make_size_select($product) {
    echo '<select name="unit_menu">';
    $price_set = array(
        'halfpint'=>$product['halfpint'],
        'pint'=>$product['pint'],
        'dk'=>$product['dk'],
        'quart'=>$product['quart']);

    $handles = array(
        'halfpint'=>'Half Pint (8 oz)',
        'pint'=>'Pint (16 oz)',
        'dk'=>'Dutch Kettle (16 oz)',
        'quart'=>'Quart (32 oz)');

    foreach ($price_set as $key=>$value) {
        if ( $value > 0.00) {
            echo '<option value="'.$value.'">'.$handles[$key].'</option>';
        }
    }
    echo '</select>';
}
?>

现在让我们把它放在一起并挂钩一个函数，用你为变量global $post; $terms = get_the_terms( $post->ID, 'product_cat' ); foreach ($terms as $term) { $category_id = $term->term_id; break; }选择的值附加的新标题替换你当前的标题

if ($category_id == "1"){
        $sku = "your_value_if_current_cat_id_is_2";
}elseif ($category_id == "2"){
        $sku = "your_value_if_current_cat_id_is_2";
}else{
        $sku = "your_value_for_all_other_categories";
}

将该函数放入functions.php文件

使用MySQL预先添加特定产品类别的产品名称
