Codeigniter上传PDF问题
|
我正在使用codeigniter上载库上载PDF，如果用户要添加印刷机，则会上载PDF，使用相同的表单来添加新文章。两者之间的区别在于新闻稿需要PDF，而新闻文章则不需要。
但是，当我提交表单而未在上传字段中添加PDF时，出现错误
您没有选择要上传的文件
我该如何做才能没有上传文件？
function add ()
{
$data = array();
//set some validation rules
$this->form_validation->set_rules(\'headline\', \'headline\', \'required|trim\');
$this->form_validation->set_rules(\'tagline\', \'tagline\', \'trim\');
$this->form_validation->set_rules(\'userfile\', \'userfile\', \'trim\');
$this->form_validation->set_rules(\'article\', \'article\', \'required|trim|htmlspecialchars\');
if ($this->form_validation->run() == FALSE)
{
$this->load->view(\'templates/admin_header.php\', $data);
$this->load->view(\'admin/news/add\');
$this->load->view(\'templates/footer.php\');
}
else
{
//validation has been passed and we save the data and if there is one present we can upload the PDF
if($this->input->post(\'userfile\') != \"\")
{
$config[\'upload_path\'] = \'./assets/doc/\';
$config[\'allowed_types\'] = \'pdf\';
$config[\'max_size\'] = \'5000\';
$this->load->library(\'upload\', $config);
if(!$this->upload->do_upload())
{
//try and do the upload if there is a problem we are going to show the form and an error
$data[\'error\'] = array(\'upload_error\' => $this->upload->display_errors());
//die(print_r($data, \'upload\'));
$this->load->view(\'templates/admin_header.php\', $data);
$this->load->view(\'admin/news/add\', $data);
$this->load->view(\'templates/footer.php\');
}
}
else
{
//everyhting has gone well the file has been upload so we can carry on and create an array of the POST data and the filename
//to save in the database.
//$file = $this->upload->data();
$insertData = array(
\'headline\' => $this->input->post(\'headline\'),
\'tagline\' => $this->input->post(\'tagline\'),
//\'pdf\' => //$file[\'file_name\'],
\'article\' => $this->input->post(\'article\')
);
$this->load->model(\'newsArticles\');
$this->session->set_flashdata(\'sucess\', \'Your news article was successfully saved\');
redirect(\'/admin/dashboard\', \'redirect\');
}

if (isset($_FILES[\'userfile\'])) { // upload the file $this->upload->do_upload(); // check errors etc } else { // do nothing }朗排谎纷瘟
之外，因此您尚未完成功能。这是CI用户指南中的示例上传脚本：function do_upload() { $config[\'upload_path\'] = \'./uploads/\'; $config[\'allowed_types\'] = \'gif|jpg|png\'; $config[\'max_size\'] = \'100\'; $config[\'max_width\'] = \'1024\'; $config[\'max_height\'] = \'768\'; $this->load->library(\'upload\', $config); if ( ! $this->upload->do_upload()) { $error = array(\'error\' => $this->upload->display_errors()); $this->load->view(\'upload_form\', $error); } else { $data = array(\'upload_data\' => $this->upload->data()); $this->load->view(\'upload_success\', $data); } }之前用检查上传文件
