Question

这个类在单个数组上工作得很好，但是当我添加多维数组时，不要工作。我创建自动获取列名和值的类。这是演示代码阵列就是这样的。

class myform{
    public $key;
    public $value;
    public $query;
    public $con;
    public function __construct(){
    $this->con = new mysqli('localhost','root','','form')or die('you are losing your mind');}   
   public function form_values($tablename,$values){
    $columns = implode(", ",array_keys($value));
    $escaped_values = array_map('esc_sql', array_values($value));
    $values  = implode("',' ", $escaped_values);
    foreach($valuee as $key => $valued){       
    $this->query = "INSERT INTO {$tablename} ($columns)VALUES('$valued[$key]')"; 
       } return $this->query;
   }
}

以下是此代码的用法

if(isset($_POST['submitt'])){
    $new = new myform;
    $values = $_POST;
    $query_form = $new->form_values('myguests',$values);
}

Answer 1

通常，允许用户直接构建对DB的查询是一个坏主意。

根据您的情况 - 在方法开头form_values添加代码：

foreach($values as $key => $value) {
    if (!is_string($value)) {
       //do some stuff. Remove element from array, or convert it to string
    }
}

雅虎......我自己就是这里的解决方案，希望有人能提供帮助。

class myform{
    public $key;
    public $value;
    public $query;
    public $con;
    public function __construct(){
    $this->con = new mysqli('localhost','root','','data') or die('you are losing your mind');
                                }   

    public function array_implode( $array) {
    if ( ! is_array( $array ) ) return $array;
    $string = array();
    foreach ( $array as $key => $val ) {
        if ( is_array( $val ) )
            $val = implode( ',', $val );
        $string[] = "{$val}";

                                        }
    return $string;

}
   public function form_values($tablename,$values){
//  unset($values['sections']);

    $array = $values;

    echo '<pre>';   
    var_export($dg);
    echo '</pre>';

    $columns = implode(", ",array_keys($values));
    $escaped_values = array_map('esc_sql', array_values($dg));
    $values  = implode("',' ", $escaped_values);
    $this->query = "INSERT INTO {$tablename} ($columns)VALUES($values)"; 
    return $this->query;
   }

public function insert_form($query_form){


    $stmt = $con->prepare($query_form) or trigger_error("ponka");
    $stmt->execute();

}       
}

用法

$new = new myform;
    $values = $_POST;
    $final_values = $new->array_implode($values);
    $query_form = $new->form_values('wp_cv',$final_values);
    $new->insert_form($query_form);
