Question

我在控制器中有2个功能。

连接到表单并进行验证。
图片上传的回调功能。

这只会在db中插入一个图像的路径。如果我从回调函数中回显print_r，它会显示所有图像，但仅来自验证函数。

    // Some Validation
    } else {
        $this->fileupload_check();

        $data['uploadedimage'] = $this->upload->data();
        $image_name = $data['uploadedimage']['file_name'];
        //echo '<pre>';
        //print_r($this->upload->data());
        $data['uploadedimage'] = $image_name;

        $this->load->model('admin/model_users');
        if($query = $this->model_users->insert_property_details($data)) {
        redirect('dashboard/property-successfully-posted');
    }

回调图片上传：

public function fileupload_check() {
$number_of_files = sizeof($_FILES['uploadedimages']['tmp_name']);
$files = $_FILES['uploadedimages'];
for($i=0;$i<$number_of_files;$i++) {
  if($_FILES['uploadedimages']['error'][$i] != 0) {
    $this->form_validation->set_message('fileupload_check', 'At least 1 image needs to be uploaded in jpeg, png or gif format only.');
    return FALSE;
  }
}
$this->load->library('upload');
$config['upload_path'] = FCPATH . 'uploads/';
$config['allowed_types'] = 'gif|jpg|png';
for ($i = 0; $i < $number_of_files; $i++) {
  $_FILES['uploadedimage']['name'] = $files['name'][$i];
  $_FILES['uploadedimage']['type'] = $files['type'][$i];
  $_FILES['uploadedimage']['tmp_name'] = $files['tmp_name'][$i];
  $_FILES['uploadedimage']['error'] = $files['error'][$i];
  $_FILES['uploadedimage']['size'] = $files['size'][$i];
  $this->upload->initialize($config);
  if ($this->upload->do_upload('uploadedimage')) {
    $data['uploadedimage'] = $this->upload->data();
    $image_name = $data['uploadedimage']['file_name'];
    $data['uploadedimage'] = $image_name;
  } else {
    $this->form_validation->set_message('fileupload_check', $this->upload->display_errors());
    return FALSE;
  }
}
return TRUE;
}

我试图传递来自“回拨图片上传”的价值＆＃39;功能到验证功能但它只传递一个图像而不是所有选择的图像。

试试这个编码...

public function fileupload_check() {

$Error_bool = TRUE;
$Error = '';

$number_of_files = sizeof($_FILES['uploadedimages']['tmp_name']);
$files = $_FILES['uploadedimages'];
for($i=0;$i<$number_of_files;$i++) {
  if($_FILES['uploadedimages']['error'][$i] != 0) {
    $Error_bool = FALSE;
    $Error = 'At least 1 image needs to be uploaded in jpeg, png or gif format only.';
  }
}
$this->load->library('upload');
$config['upload_path'] = FCPATH . 'uploads/';
$config['allowed_types'] = 'gif|jpg|png';
for ($i = 0; $i < $number_of_files; $i++) {
  $_FILES['uploadedimage']['name'] = $files['name'][$i];
  $_FILES['uploadedimage']['type'] = $files['type'][$i];
  $_FILES['uploadedimage']['tmp_name'] = $files['tmp_name'][$i];
  $_FILES['uploadedimage']['error'] = $files['error'][$i];
  $_FILES['uploadedimage']['size'] = $files['size'][$i];
  $this->upload->initialize($config);
  if ($this->upload->do_upload('uploadedimage')) {
    $data['uploadedimage'] = $this->upload->data();
    $image_name = $data['uploadedimage']['file_name'];
    $data['uploadedimage'] = $image_name;
  } else {
    $Error_bool = FALSE;
    $Error =  $this->upload->display_errors();
  }
}

if($Error_bool == FALSE) {
    $this->form_validation->set_message('fileupload_check', $Error);
    return FALSE;
} else {
    return TRUE;
}


}

Answer 2

最简单的方法是创建一个serialcodes_id并在其中发送session并在另一个函数中访问该会话。

如果你想破坏会话

，你可以在之后销毁会话

Answer 3

我必须对其进行一些更改才能使其正常工作，

我直接在FORM函数中包含了整个回调函数代码，并完全删除了回调函数。

这也有助于另外一件事。之前在表单验证错误的情况下，错误图像被上传到上传文件夹，但现在他们没有。

我不得不在do_upload中做一些改动（通过添加$ i＆amp; implode），这有助于我在db行中插入多个图像路径。
