php foreach循环只有一行

Question

我使用foreach循环从控制函数调用模型函数，以便将值插入数据库。但该功能只插入一行。 这是我的控制功能：

public function insert()
    {
        if(!isset($_REQUEST['UserContacts']))
        {
            echo json_encode('No Data Uploaded');
            exit;
        }
//        if(!isset($_REQUEST['userIndex']))
//        {
//            echo json_encode('userIndex not provided');
//            exit;
//        }
        $contactList =$this->model->getContact();
        $userIndex=1;
        $contact=null;
        foreach($contactList as $contact)
        {
            echo "inside foeach";
            $this->model->fields = array();
            echo "post contact no".$contact['phone_number']."<br>";
            array_push($this->model->fields, $contact['phone_number']);
            array_push($this->model->fields, $contact['contact_name']);
            array_push($this->model->fields, 'aaa@ff.cc');
            array_push($this->model->fields, $userIndex);
            $rowcount = $this->model->insertcontactsync();
            echo $rowcount;

        }


    }

这是我的模型功能代码：

public function insertcontactsync()
    {
        $query1 = "INSERT INTO `contact_sync`(`userIndex`, `contactName`, `contactEmail`, `contactNumber`,`status`, `contactCreatedOn`, `contactModifiedOn`) VALUES ('".$this->fields[3]."','".$this->fields[1]."','".$this->fields[2]."',".$this->fields[0].",'no match','".date("Y-m-d H:i:s")."','".date("Y-m-d H:i:s")."')";
        //print_r($query1);
        echo "<br>";
        $result = $this->connect->query($query1);
    echo $result;
}
