Question

I am new user to using code igniter in my project, I am facing one problem while uploading multiple files but the last one only insert to all image three images field.

Answer 1

code of controller.

public function upload_multiple($field_name,$path){
    $this->load->library('upload');
    $files = $_FILES;
    $cpt = count($_FILES[$field_name]['name']);//count for number of image files
    $image_name =array();
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES[$field_name]['name']= $files[$field_name]['name'][$i];
        $_FILES[$field_name]['type']= $files[$field_name]['type'][$i];
        $_FILES[$field_name]['tmp_name'] = $files[$field_name]['tmp_name'][$i];
        $_FILES[$field_name]['error']= $files[$field_name]['error'][$i]; 
        $_FILES[$field_name]['size'] = $files[$field_name]['size'][$i];

        $this->upload->initialize($this->set_upload_options($path));
         //for initalizing configuration for each image
        $this->upload->do_upload($field_name);  

        $data = array('upload_data' => $this->upload->data()); 
        $image_name[]=$data['upload_data']['file_name'];
        //store file name into array

    }
    return $image_name;//all images name which is uploaded
}
public function set_upload_options($path)
{   
    $config = array();
    $config['upload_path'] = $path;
    $config['allowed_types'] = '*';
    $config['overwrite']     = FALSE;

    return $config;
}

call function

 $image_name=$this->upload_multiple('profile_image',$path=USER_OTHER);//we get all name of uploaded file in $image_name array.
