使用codeigniter进行多个图像上传

Question

im having a page that will insert username, ID and the user must be able to upload upto 10 images .

The main problem that im having is when it comes to uploading multiple images using codeigniter.

1. can someone suggest me how can i pass each image path of each individual image to the array so i can pass it to the database.

2. and if the user selects to upload less than 10 images, like 2 or 5 then how can i ignore the error that says a file hasn't been selected and jst pass only the images that has been uploaded.

   <form method="post" action="uploader/go" enctype="multipart/form-data">
   <input name="username" type="text" /><br />
   <input name="nid" type="text" /><br />
   <input type="file" name="image1" /><br />
   <input type="file" name="image2" /><br />
   <input type="file" name="image3" /><br />
   <input type="file" name="image4" /><br />
   <input type="file" name="image5" /><br />
   <input type="file" name="image6" /><br />
   <input type="file" name="image7" /><br />
   <input type="file" name="image8" /><br />
   <input type="file" name="image9" /><br />
   <input type="file" name="image10" /><br />
   <input type="submit" name="go" value="Upload!!!" />
   </form>
   

sample controller

$image_data=array('image_info' => $this->upload->data('image')); 
$image_path=$image_data['image_info']['full_path'];

$data =array(
            'id'=>uniqid('id_'),
                    'nID'=>$this->input->post('nid'),
            'username'=>$username,
            'image1'=>$image_path
}

any help will be appreciated.

Answer 1

change the input names to:

<input type="file" name="image[1]" /><br />
<input type="file" name="image[2]" /><br />
<input type="file" name="image[3]" /><br />

instead and $this->upload->data('image') will be an array.

And then you can do:

foreach($this->upload->data('image') as $image) {
   passItToTheDatabase(); // your custom function

}
