在CodeIgniter docs here

该部分底部的注释说明:

  

您还可以处理传递给回调的表单数据并将其返回。如果你的回调返回布尔值以外的任何东西,则假定数据是你新处理的表格数据。

我有一个回调函数可以验证图片上传并进行上传,如下所示:

public function upload() {
    $this->form_validation->set_rules('imageFile', 'Image', 'callback_validate_image');
    // ...
}

然后是回调函数:

public function validate_image() {

        if (empty($_FILES['imageFile'])) {
            $this->form_validation->set_message('validate_image', 'Please select a file');
            return false;
        }

        $config = array (
            'upload_path' => './uploads/',
            'allowed_types' => 'jpg|jpeg|png|gif',
            'max_size' => '5048576'
        );

        $this->load->library('upload', $config);

        if (!$this->upload->do_upload('imageFile')) {
            $this->form_validation->set_message('validate_image', $this->upload->display_errors());
            return false;
        } else {
            $data = array('upload_data' => $this->upload->data());
            return $data;
        }

}

如何将$data返回到upload函数,以便我可以在一个查询中将所有数据插入数据库?

如果我做了你的代码部分,我会这样做

function upload() 
{

    // 'required' doesn't work on file inputs so use empty()
    if (empty($_FILES['imageFile'])) {
        // show error message
    }

    if ($this->form_validation->run() == FALSE)
    {
            echo "Please select a file";
            //$this->load->view('myform');
    }
    else
    {
        $config = array (
            'upload_path' => './uploads/',
            'allowed_types' => 'jpg|jpeg|png|gif',
            'max_size' => '5048576'
        );

        $this->load->library('upload', $config);

        if (!$this->upload->do_upload('imageFile')) 
        {
            $this->form_validation->set_message('validate_image', $this->upload->display_errors());
            return false;
        } 
        else {
            $data['upload_data'] = $this->upload->data();
            $data['form_data'] = $this->input->post(NULL, TRUE);
            var_dump($data);
        }
    }
}
  

没有通过上传部分。在运行之前测试它
