图像路径未上传到数据库php代码点火器



我正在尝试用带有图像的产品信息构建一个项目。我已经尝试了下面给出的一些代码,但我无法上传数据库中的图像路径。我是一个试图学习代码的新手。

控制器代码:-

class Category extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model('Category_model');
}
private function do_upload(){
$config['upload_path']='./uploads/';
$config['allowed_types']        = 'gif|jpg|png';
$config['max_size']             = 1000;
$config['max_width']            = 1024;
$config['max_height']           = 768;
$this->load->library('upload', $config);
if (  ! $this->upload->do_upload('product_image')){
$error = array('error' => $this->upload->display_errors());
$this->load->view('admin/pages/add_product_form', $error);
}     
else
{
$upload_data = $this->upload->data();
$this->Category_model->insert_data( $upload_data['upload_path']);
}

$data = array('upload_data' => $this->upload->data());
}
function  save_product(){
$this->do_upload();
$this->session->set_userdata('message','Product saved successfully');
$this->add_product();
}
}

型号代码:-

function insert_data( $path_name){
$data = array(
'product_image'    => $path_name
);
$data['product_status']=1;
$this->db->insert('tbl_product', $data);

}

查看代码:-

<form class="form-horizontal" action="<?php echo base_url()?>index.php/Category/save_product" enctype="multipart/form-data" method="post">
<fieldset>
<div class="control-group">
<label class="control-label" for="typeahead">Product Name </label>
<div class="controls">
<input type="text" name="product_name" class="span6 typeahead" id="typeahead"  data-provide="typeahead" data-items="4" >
</div>
</div>


<div class="control-group">
<label class="control-label" for="selectError3">Product Category</label>
<div class="controls">
<select name="product_category" id="selectError3">
<option>Select Category</option>
<?php foreach($category_info as $category){ ?>
  <option value="<?php echo $category->category_id ?>"><?php echo $category->category_name; ?></option>

<?php } ?>   
<option>Option 2</option>
<option>Option 3</option>
<option>Option 4</option>
<option>Option 5</option>
</select>
</div>
</div>
<div class="control-group">
<label class="control-label" for="typeahead">Product Image </label>
<div class="controls">
<input name="product_image" type="file" name="fileToUpload" id="fileToUpload">
</div>
</div>
<div class="form-actions">
<button type="submit" class="btn btn-primary">Save changes</button>
<button type="reset" class="btn">Cancel</button>
</div>
</fieldset>
</form>   

这是我上面给出的代码,但仍然没有得到数据库中的图像路径,请在这方面提供帮助。提前感谢。

只增加了max_size、max_width和max_height,这些就解决了问题。
