Question

我正在尝试更新Wordpress中的多行。

<?php
$data_type = array('%d','%d','%d','%d','%d');
$convert_datatype = implode(",",$data_type);
$list_ids = array(12,1,2,3,45); 
$wpdb->query( $wpdb->prepare( "UPDATE wp_testimonials SET status = %d WHERE ID IN (".$convert_datatype.") ", 1, $list_ids ) );
?>

错误消息

警告：mysqli_query（）：第1924行的wp-includes \ wp-db.php中的空查询

Answer 1

尝试删除IN（“。$ convert_datatype。”）并将其替换为 IN $ convert_datatype

因此（未经测试）：

$data_type = array('%d','%d','%d','%d','%d');

$convert_datatype = implode(",",$data_type);

$list_ids = array(12,1,2,3,45); 

$wpdb->query( 
   $wpdb->prepare( 
      "UPDATE wp_testimonials SET status = %d WHERE ID IN ($convert_datatype)", 1, $list_ids
   ) 
);

尝试这是最后的手段：

 $wpdb->query( 
   $wpdb->prepare( 
      "UPDATE wp_testimonials SET status = %d WHERE ID IN ( %d, %d, %d, %d, %d )", 1, 12,1,2,3,45
   ) 
);

Answer 2

试试这个：

global $wpdb;

$list_ids = array(12,1,2,3,45);

$sql = "UPDATE wp_testimonials SET status = %d WHERE ID IN (" . implode(',', array_fill(0, count($list_ids), '%d') ) . ")";

$query = call_user_func_array(array($wpdb, 'prepare'), array_merge( array($sql), array(1), $list_ids));

$wpdb->query( $query );
