 <td>  
                        <div class="form-group"><span id="file_error"></span>  
                       <input type="file" name="file" id="file" class="form-control span12">  
                       </div>  
                       </td>  
                                                       </tr>  
 <tr align="center">  
                                                  <td colspan="2"><input type="submit" value="Upload File" name="submit" class="btn btnSubmit btn-primary btn-lg"></td>  
                                                       </tr>  
                                           </tbody>  
                                    </table>  

Now processing the form with php. Create a php file with extension .php. Now start php script to upload file to the server in php. if condition is used when a submit button is clicked by the user. Define directory “upload” to save the uploaded file there. $dir varible contain the the “upload” directory where we upload file to save. After that create a superglobal variable to assign value of file filed. $_FILE[] is an associative Array. Now check for the upload file that user upload a file a empty. If upload file is not empty then we check that file is already uploaded or not.if yes then we rename the file by adding time with time() function. Now create a $fdir variable which is the full directory of uploading file. . temp folder is contain inside the www folder. when we upload a file it temporarily upload to temp file and then we move the file form temp directory to the directory we define. Now move file from temp folder to directory we difine by using the php function move_uploaded_file. At last execute the query to save the file name to database.
