我的提交表单有问题。我提出了一个查询来提交产品，你必须添加有关该产品的信息以及产品的图像。以下是我的代码：
控制器：
<?php
public function save(){
$this->load->library('upload');
$image_path = realpath(FCPATH.'images');
$config['upload_path'] = $image_path;
$config['allowed_types'] = 'jpg|png|jpeg|gif';
$config['max_size'] = '2048';
$config['encrypt_name'] = TRUE;
$config['remove_spaces'] = TRUE;
$config['detect_mime'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('default_img')) {
$error = array('error' => $this->upload->display_errors());
print_r($error);
} else {
$data = $this->upload->data();
print_r($data);
}
$this->form_validation->set_rules('nume', 'Nume produs','required');
$this->form_validation->set_rules('descriere_full', 'Descriere produs','required');
$this->form_validation->set_rules('scurta_descriere', 'Descriere scurta','required');
$this->form_validation->set_rules('type', 'Tip produs','required');
$this->form_validation->set_rules('dimensiuni_1', 'Stock produs','');
$this->form_validation->set_rules('stock_1', 'Stock produs 1','required');
$this->form_validation->set_rules('pret_1', 'Pret produs 1','required');
$this->form_validation->set_rules('dimensiuni_2', 'Stock produs','');
$this->form_validation->set_rules('stock_2', 'Stock produs 1','');
$this->form_validation->set_rules('pret_2', 'Pret produs 1','');
$this->form_validation->set_rules('dimensiuni_3', 'Stock produs','');
$this->form_validation->set_rules('stock_3', 'Stock produs 1','');
$this->form_validation->set_rules('pret_3', 'Pret produs 1','');
//
if ($this->form_validation->run())
{
$data = $this->input->post();
$data = $this->security->xss_clean($data);
unset($data['submit']);
if ($this->Queries->addProduct($data)) {
$this->session->set_flashdata('msg', 'Produs adaugat cu succes');
}
else
{
$this->session->set_flashdata('msg', 'Din pacate produsul nu a putut fi adaugat');
}
return redirect('Dashboard');
}
else
{
$this->load->view('admin/template/header');
$this->load->view('admin/products/create');
$this->load->view('admin/template/footer');
}
}
?>
