如何将form_validation设置为Codeigniter中的文件所需？

Question

我想设置form_validation为FILES在笨.我写了以下代码.它的工作正常,input fields但它不能正常工作input files.

视图

    <tr><th>Price</th><td>         <input type="text"  name="price"> </td></tr>              
    <tr><th>Color</th><td>         <input type="text"  name="color"> </td></tr>                
    <tr><th>Size</th><td>          <input type="text"  name="size"> </td></tr>                 




    <tr><th>Front Image</th><td>    
                    <input type="file" name="userfile_1">          </td></tr> 


   <tr><th>Right Sleeves Images</th><td>
                    <input type="file" name="userfile_2">          </td></tr> 


    <tr><th>Left Sleeves Images</th><td>
                    <input type="file" name="userfile_3"></td></tr>         


     <tr><th>Back Image</th><td>
                    <input type="file" name="userfile_4">          </td></tr> 

    <tr><th>Submit </th><td><input type="submit"    value="Insert"> </td></tr> 

CONTROLLER

$this->form_validation->set_rules('product_name','Product Name','required');
$this->form_validation->set_rules('price','Price','required');
$this->form_validation->set_rules('color', 'Color','required');

$this->form_validation->set_rules('userfile_1','Image 1','required');
$this->form_validation->set_rules('userfile_2','Image 2','required');
$this->form_validation->set_rules('userfile_3','Image 3','required');
$this->form_validation->set_rules('userfile_4','Image4','required');

我已经加载了所有必需的库和助手.它适用于输入字段,但对于它所说的图像Image 1 is required,即使在我上传image1之后,其余文件也会发生同样的事情.

请指导我如何解决这个问题.

谢谢塔哈

你可以尝试:

if (empty($_FILES['userfile_1']['name']))
{
$this->form_validation->set_rules('userfile_1','Image 1','required');
}
if (empty($_FILES['userfile_2']['name']))
{
$this->form_validation->set_rules('userfile_2','Image 2','required');
}
if (empty($_FILES['userfile_3']['name']))
{
$this->form_validation->set_rules('userfile_3','Image 3','required');
}
if (empty($_FILES['userfile_4']['name']))
{
$this->form_validation->set_rules('userfile_4','Image4','required');
}
