没有图片上传在codeigniter

Question

我与此战斗已经1个半小时，但无法找到问题。我使用笨和上传功能，但它总是失败上传 -

控制器 -

// Uploads the picture to server 
    public function uploadPicture() 
    { 
    $this->load->helper(array('form', 'url')); 
    $this->load->helper('url'); 
     $config['upload_path'] = './images/pictures/'; 
     $config['allowed_types'] = 'gif|jpg|png'; 
     $config['max_size'] = '700'; 
     $config['max_width'] = '1024'; 
     $config['max_height'] = '768'; 

     $this->load->library('upload', $config); 

     $this->upload->do_upload(); 

     if (! $this->upload->do_upload()) 
     { 
      $data = array('upload_data' => $this->upload->data());  

      var_dump($data); 
     //redirect('/profile/changePicture', 'refresh'); 
     } 
     else 
     { 
     redirect('/profile/changePicture', 'refresh');    
     } 
    } 

视图 -

<form class="fix-this form" method="post" action="/savieno/profile/uploadPicture" enctype="multipart/form-data"> 
        <div class="formfield">      
         <label id="current-password-error" class="input-error" style="display: none;"></label>   
         <span class="profile">Tava bilde: </span>         
         <input id="picture" name="picture" class="with-label" style="width: 270px;" type="file" placeholder="Tava bilde" /> 
         <label>*</label> 
    </div>      
        <input type="submit" id="submit" value="Labot Profilu" name="edit" class="fix-this" />   
    </form> 

后，我选择没有图像，或者如果我选择图片，它给我var_dump与detials -

array 
    'upload_data' => 
    array 
     'file_name' => string '' (length=0) 
     'file_type' => string '' (length=0) 
     'file_path' => string './images/pictures/' (length=18) 
     'full_path' => string './images/pictures/' (length=18) 
     'raw_name' => string '' (length=0) 
     'orig_name' => string '' (length=0) 
     'client_name' => string '' (length=0) 
     'file_ext' => string '' (length=0) 
     'file_size' => string '' (length=0) 
     'is_image' => boolean false 
     'image_width' => string '' (length=0) 
     'image_height' => string '' (length=0) 
     'image_type' => string '' (length=0) 
     'image_size_str' => string '' (length=0) 

可能是什么问题？

$config['upload_path'] = './images/pictures/';请确保您写入的路径是正确的，并且具有将文件写入到的适当777权限。

另外，正如克里斯蒂安写道，你正在做$this->upload->do_upload();上传部分两次。

检查错误，你可以这样做：

<?php 
if(!$this->upload->do_upload())   
{ 
    echo $this->upload->display_error(); 
    return FALSE; 
} 
else 
{ 
    $data = $this->upload->data(); 
    return TRUE; 
}
