我需要一些幫助，請掙扎，用AJAX上傳和PHP
我上傳裝載有一個jQuery上傳的幫助的圖像，使用戶可以得到它的圖像的預覽，我可以jCrop ，我的問題是，然後我需要保存的文件名，但我不能得到我的上傳功能創建變量，
用戶去通過量是如下的方法，
- 用戶填寫在他們的細節
- 用戶選擇S和圖像擡起負荷並點擊了上傳按鈕
- 上傳功能運行，並且該圖像被返回到圖
- 用戶選擇將要剪切的圖像的區域，並保存
- 用戶進行填充形成了
- 保存的物品包括文件名
下面是我的PHP代碼，我相信這是其中變量就不復存在了，不能在add函數中使用，
添加（） - 該函數的形式提交過
public function add()
{
$this->form_validation->set_rules('title','title', 'required|trim|min_length[2]');
$this->form_validation->set_rules('firstname', 'firstname', 'required|trim|alpha');
$this->form_validation->set_rules('surname', 'surname', 'required|trim|alpha');
$this->form_validation->set_rules('email', 'email address', 'required|trim|valid_email');
$this->form_validation->set_rules('postcode', 'postcode', 'required|trim|min_length[6]|max_length[9]');
$this->form_validation->set_rules('company_name', 'company_name', 'required|trim');
$this->form_validation->set_rules('company_summary', 'company_summary', 'required|trim|max_length[3000]');
$this->form_validation->set_rules('alternative_ads', 'alternative ads', 'required|trim|prep_url');
$this->form_validation->set_rules('facebook_url', 'Facebook URL', 'required|trim|prep_url');
$this->form_validation->set_rules('twitter_url', 'Twitter URL', 'required|trim|prep_url');
if($this->form_validation->run() == FALSE)
{
$this->template->build('admin/users/add');
}
else
{
//group the post data together soe that we can save the data easily.
$user = array(
'firstname' => $this->input->post('firstname'),
'surname' => $this->input->post('surname'),
'email' => $this->input->post('email'),
'postcode' => $this->input->post('postcode'),
'date_registered' => date("d-m-y h:i:s", time())
);
if(!$this->users_model->insert($this->input->xss_clean($user)))
{
$data['error'] = "We could not save you details, please try again";
$this->template->build('/users/admin/add', $data);
}
$employer = array(
'company_name' => $this->input->post('company_name'),
'company_summary' => $this->input->post('company_summary'),
'logo' => $this->file['file_name'],
'alternative_ads' => $this->input->post('alternative_ads'),
'facebook_url' => $this->input->post('facebook_url'),
'twitter_url' => $this->input->post('twitter_url'),
'user_id' => $this->db->insert_id()
);
if(!$this->employer_model->insert($this->input->xss_clean($employer)))
{
$data['error'] = "We could not save you details, please try again";
$this->template->build('/users/admin/add', $data);
}
else
{
die(print_r($this->file));
$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['source_image'] = '/media/uploads/users/' . $this->file['file_name'];
$config['thumb_marker'] = TRUE;
$config['x_axis'] = $this->input->post('x');
$config['y_axis'] = $this->input->post('y');
$this->image_lib->initialize($config);
if (! $this->image_lib->crop())
{
$data['error'] = "We could not crop you image, please try again. If the problem persists please contact us";
$this->template->build('/admin/users/add', $data);
}
$this->session->set_flashdata('success', 'You have successfully added an employer');
redirect('/admin/users/manage');
}
}
}
這jQuery的上傳者稱
private function upload()
{
$config['upload_path'] = "./media/uploads/users";
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['encrypt_name'] = TRUE;
$this->load->library('upload');
$this->upload->initialize($config);
if (! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
die(print_r($error));
}
else
{
$this->file = $this->upload->data();
$msg = $this->file;
echo json_encode($msg);
}
}
回顧一下我在上傳設置$this->file（），並試圖上傳功能在add（）函數中使用它。
