Codeigniter(将类别数据插入表中)

Question

我是CodeIgniter的新手，我执行了前开发人员留下的一个电子商务项目。情况是类别数据没有插入到我的表中。

控制器和模型中的代码都很长，但我把它删掉了，只发布了必要的部分

这是我的控制器。

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Category extends Admin_Controller {
public function create()
{
/* Breadcrumbs */
$this->breadcrumbs->unshift(2, "New Category" , 'admin/category/create');
$this->data['breadcrumb'] = $this->breadcrumbs->show();
/* Variables */
$tables = $this->config->item('tables', 'ion_auth');
/* Validate form input */
$this->form_validation->set_rules('cat_name', 'Category Name', 'trim|required');       

if ($this->form_validation->run() == TRUE)
{
$config['upload_path'] =  './assets/uploads/category/';
//die(var_dump(is_dir($config['upload_path'])));
$config['allowed_types'] = 'png,jpeg';
$config['max_size']    = '1024';
$this->load->library('upload', $config);
$this->upload->initialize($config);
$img = "icon";
if ( ! $this->upload->do_upload($img))
{
$this->session->set_flashdata('error', $this->upload->display_errors());
redirect('admin/category');
}
else
{
$data=$this->upload->data();
$file = array('file_name' => $data['file_name'] );
$data = array('upload_data' => $this->upload->data());
$photo = base_url().'assets/uploads/category/'.$file['file_name'];
$data = array(
'category_name' => $this->input->post('cat_name'),
'category_photo'  => $photo,
'category_description'    => $this->input->post('cat_desc')
);
$this->category_model->insertcategory($data);
//$this->ion_auth->messages()
$this->session->set_flashdata('message', "Successfully inserted!");
redirect('admin/category', 'refresh');
}
}
else
{
$this->data['message'] = (validation_errors() ? validation_errors() : ($this->ion_auth->errors() ? $this->ion_auth->errors() : $this->session->flashdata('message')));           
/* Load Template */
$this->template->admin_render('admin/category/create', $this->data);
}
}

这是我的模型。

class Category_model extends CI_Model
{
function insertcategory($data) {
$query = $this->db->insert('category', $data);
if ($query) {
return true;
} else {
return false;
}
}

这是我的表格。

<div class="box-body">
<span style="color:red"><?php echo $message;?></span>
<?php echo form_open_multipart(current_url(), array('class' => 'form-horizontal', 'id' => 'form-create_user')); ?>
<div class="form-group">
<span class="col-sm-2 control-label">Category Name</span> 
<div class="col-sm-10">
<input type="text" class="form-control" id="cat_name" placeholder="Category Name" name="cat_name" required>
</div>
</div>
<div class="form-group">
<span class="col-sm-2 control-label">Category Description</span> 
<div class="col-sm-10">
<input type="text" class="form-control" id="cat_desc" placeholder="Description" name="cat_desc" >
</div>
</div>
<div class="form-group">
<span class="col-sm-2 control-label">Category Icon</span> 
<div class="col-sm-10">
<input class="input-file uniform_on" id="icon" name="icon" type="file">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="btn-group">
<?php echo form_button(array('type' => 'submit', 'class' => 'btn btn-primary btn-flat', 'content' => lang('actions_submit'))); ?>
<?php echo form_button(array('type' => 'reset', 'class' => 'btn btn-warning btn-flat', 'content' => lang('actions_reset'))); ?>
<?php echo anchor('admin/category', lang('actions_cancel'), array('class' => 'btn btn-default btn-flat')); ?>
</div>
</div>
</div>
<?php echo form_close();?>
</div>
