Php 数据库查询在视图中显示而不是$data

下面的代码似乎显示在“视图”中，而不是通过

$data

显示（我还没有将

$data['companyName']

回显到我的视图中，但是

$data['pageTitle']

工作正常）

问题：

function companyName()
    {
        $companyName = $this->db->query("SELECT company_name FROM core");

        if ($companyName->num_rows() > 0)
        {
            foreach ($companyName->result() as $row)
            {
                echo $row->company_name;
            }
        }

public function index()
{
    $data['companyName'] = $this->core_model->companyName();
    $data['pageTitle'] = "Admin Login";
    $this->load->view('admin/assets/header', $data);
    $this->load->view('admin/login.php');
    $this->load->view('admin/assets/footer');
}

型号：

function companyName()
    {
        $companyName = $this->db->query("SELECT company_name FROM core");

        if ($companyName->num_rows() > 0)
        {
            foreach ($companyName->result() as $row)
            {
                echo $row->company_name;
            }
        }

public function index()
{
    $data['companyName'] = $this->core_model->companyName();
    $data['pageTitle'] = "Admin Login";
    $this->load->view('admin/assets/header', $data);
    $this->load->view('admin/login.php');
    $this->load->view('admin/assets/footer');
}

控制器：

function companyName()
    {
        $companyName = $this->db->query("SELECT company_name FROM core");

        if ($companyName->num_rows() > 0)
        {
            foreach ($companyName->result() as $row)
            {
                echo $row->company_name;
            }
        }

public function index()
{
    $data['companyName'] = $this->core_model->companyName();
    $data['pageTitle'] = "Admin Login";
    $this->load->view('admin/assets/header', $data);
    $this->load->view('admin/login.php');
    $this->load->view('admin/assets/footer');
}

通过

echo

ing模型中的某些内容，在处理模型时会发生

echo

，这比视图在其控制器眼中闪烁还要早

相反，您应该在模型中执行以下操作：

function companyName()
{
    $companyName = $this->db->query("SELECT company_name FROM core");

    if ($companyName->num_rows() > 0)
    {
        $company_names = '';
        foreach ($companyName->result() as $row)
        {
            $company_names .= $row->company_name;
        }
    }
    return $company_names;
}

然后，您可以将

$data

传递到视图中，字符串将准备好按照您的需要进行回显
