个人资料图片将上传到文件夹,但不会屏幕 [英] Profile Image will upload to folder but not to screen
问题描述
我正在创建个人资料页面,当我选择要上传的图片时,该图片将存储在uploads文件夹中,但不会显示在屏幕上 - 为什么会这样。
图片的容器似乎出现,但不是图片
。但如果我不选择图片,上传功能会正确地返回错误上传
这是我的控制器里面的上传功能 - 我意识到这个文件夹叫做puploads:
class HomeProfile extends CI_Controller
{
function HomeProfile()
{
parent :: __ construct ;
$ this-> load-> model(profiles);
$ this-> load-> model(profileimages);
$ this-> load-> helper(array('form','url'));
}
function upload()
{
$ config = array(
'allowed_types'=> gif | jpg | jpeg | png',
'upload_path'=>'./ web-project-jb / assets / puploads /',
'max_size'=> 10000,
'max_width'=> 1024,
'max_height'=> 768
);
$ this-> load-> library('upload',$ config);
$ img = $ this-> session-> userdata('img');
$ username = $ this-> session-> userdata('username');
$ this-> profileimages-> putProfileImage($ username,$ this-> input-> post(profileimage))
// fail show upload form
if(!$ this-> upload-> do_upload())
{
$ error = array '=> $ this-> upload-> display_errors());
$ username = $ this-> session-> userdata('username');
$ viewData ['username'] = $ username;
$ viewData ['profileText'] = $ this-> profiles-> getProfileText($ username);
$ this-> load-> view('shared / header');
$ this-> load-> view('homeprofile / homeprofiletitle',$ viewData);
$ this-> load-> view('shared / nav');
$ this-> load-> view('homeprofile / homeprofileview',$ error,$ viewData,array('error'=>''));
$ this-> load-> view('shared / footer');
// redirect('homeprofile / index');
}
else
{
//上传成功,保存到数据库
$ file_data = $ this-> upload-> data();
$ data ['img'] = base_url()。'/ web-project-jb / assets / puploads /'.$ file_data ['file_name'];
//你可能希望在将图像保存到db之后从服务器中删除该图像
//检查以确保$ data ['full_path']是一个有效的路径
// get upload_sucess .php从上面的链接
// $ image = chunk_split(base64_encode(file_get_contents($ data ['file_name'])));
$ this-> username = $ this-> session-> userdata('username');
$ data ['profileimages'] = $ this-> profileimages-> getProfileImage($ username);
$ viewData ['username'] = $ username;
$ viewData ['profileText'] = $ this-> profiles-> getProfileText($ username);
$ username = $ this-> session-> userdata('username');
$ this-> load-> view('shared / header');
$ this-> load-> view('homeprofile / homeprofiletitle',$ viewData);
$ this-> load-> view('shared / nav');
$ this-> load-> view('homeprofile / homeprofileview',$ data,$ viewData);
$ this-> load-> view('shared / footer');
// redirect('homeprofile / index');
}
}
函数索引()
{
$ username = $ this-> session-> userdata('username');
$ data ['profileimages'] = $ this-> profileimages-> getProfileImage($ username);
$ viewData ['username'] = $ username;
$ viewData ['profileText'] = $ this-> profiles-> getProfileText($ username);
$ this-> load-> view('shared / header');
$ this-> load-> view('homeprofile / homeprofiletitle',$ viewData);
$ this-> load-> view('shared / nav');
// $ this-> load-> view('homeprofile / upload_form',$ data);
$ this-> load-> view('homeprofile / homeprofileview',$ data,$ viewData,array('error'=>''));
$ this-> load-> view('shared / footer');
}
}
这里是我的profileimages模型: / p>
function ProfileImages()
{
parent :: __构造();
}
函数存在($ username)
{
$ this-> db-> select('*') - > from(profileimages) - >其中('user',$ username);
$ query = $ this-> db-> get();
if($ query-> num_rows()> 0)
{
return true;
/ *
echouser $ user exists!;
$ row = $ query-> row();
echoand his profileimage is $ row-> profileimage;
* /
}
else
{
return false;
// echono such user as $ user!;
}
}
function putProfileImage($ username,$ img)
{
$ record = array('user'=> $ username,'profileimage'=> $ img);
if($ this-> exists($ username))
{
$ this-> db-> where('user',$ username) profileimages',/*'./uploads/。'* / $ record);
// appends
}
else
{
$ this-> db-> where('user',$ username) - > ; insert('profileimages',$ record);
}
}
function getProfileImage($ username)
{
$ this-> db-> select('*') - > from('profileimages') - > where('user',$ username);
$ query = $ this-> db-> get();
if($ query-> num_rows()> 0){
$ row = $ query-> row();
return $ row-> profileimage;
}
return Null;
}
}
这是我的观点:
< h3><?=个人资料图片?>< / h3&
< img src =./ web-project-jb / assets / puploads /width ='300'height ='300'/>
<?= form_open_multipart('homeprofile / upload');?>
< input type =filename =userfilevalue =/>
<?= form_submit('submit','upload')?>
<?= form_close();?>
<?php if(isset($ error))echo $ error;?>
< / div>
< / div>
我已经尝试替换img src,但我只是得到一个错误,说数据是无法识别
您的视图文件不表示尝试输出动态图像,您拥有 src
硬编码,并且不使用您的 $ img
变量(您在控制器中设置的 $ data ['img' ]
):
$ data ['img'] = base_url -project-jb / assets / puploads /'.$ file_data ['file_name'];
这里也似乎是混合服务器路径和URL。假设您上传文件夹的网址是:
http://example.com/web-project-jb / assets / puploads /
...在控制器中使用
$ data ['img'] ='web-project-jb / assets / puploads /'.$ file_data ['file_name '];
然后在您的视图中:
< img src =<?php echo base_url($ img);?> width ='300'height ='300'/>
I'm creating a profile page where when I select an image to upload it will be stored in the uploads folder but will not display to the screen - why would this be.
The container of an image seems to appear, but not the image
But the upload function does correctly thtow back an error if I don't select an image to upload
Here is my controller with the upload feature within it - i realise the folder is called puploads:
class HomeProfile extends CI_Controller
{
function HomeProfile()
{
parent::__construct();
$this->load->model("profiles");
$this->load->model("profileimages");
$this->load->helper(array('form', 'url'));
}
function upload()
{
$config = array(
'allowed_types' =>'gif|jpg|jpeg|png',
'upload_path' =>'./web-project-jb/assets/puploads/',
'max_size' => 10000,
'max_width' => 1024,
'max_height' => 768
);
$this->load->library('upload', $config);
$img = $this->session->userdata('img');
$username = $this->session->userdata('username');
$this->profileimages->putProfileImage($username, $this->input->post("profileimage"));
//fail show upload form
if (! $this->upload->do_upload())
{
$error = array('error'=>$this->upload->display_errors());
$username = $this->session->userdata('username');
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$this->load->view('shared/header');
$this->load->view('homeprofile/homeprofiletitle', $viewData);
$this->load->view('shared/nav');
$this->load->view('homeprofile/homeprofileview', $error, $viewData, array('error' => ' ' ));
$this->load->view('shared/footer');
//redirect('homeprofile/index');
}
else
{
//successful upload so save to database
$file_data = $this->upload->data();
$data['img'] = base_url().'./web-project-jb/assets/puploads/'.$file_data['file_name'];
// you may want to delete the image from the server after saving it to db
// check to make sure $data['full_path'] is a valid path
// get upload_sucess.php from link above
//$image = chunk_split( base64_encode( file_get_contents( $data['file_name'] ) ) );
$this->username = $this->session->userdata('username');
$data['profileimages'] = $this->profileimages->getProfileImage($username);
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$username = $this->session->userdata('username');
$this->load->view('shared/header');
$this->load->view('homeprofile/homeprofiletitle', $viewData);
$this->load->view('shared/nav');
$this->load->view('homeprofile/homeprofileview', $data, $viewData);
$this->load->view('shared/footer');
//redirect('homeprofile/index');
}
}
function index()
{
$username = $this->session->userdata('username');
$data['profileimages'] = $this->profileimages->getProfileImage($username);
$viewData['username'] = $username;
$viewData['profileText'] = $this->profiles->getProfileText($username);
$this->load->view('shared/header');
$this->load->view('homeprofile/homeprofiletitle', $viewData);
$this->load->view('shared/nav');
//$this->load->view('homeprofile/upload_form', $data);
$this->load->view('homeprofile/homeprofileview', $data, $viewData, array('error' => ' ' ) );
$this->load->view('shared/footer');
}
}
Here is my profileimages model:
function ProfileImages()
{
parent::__construct();
}
function exists($username)
{
$this->db->select('*')->from("profileimages")->where('user', $username);
$query = $this->db->get();
if ($query->num_rows() > 0)
{
return true;
/*
echo "user $user exists!";
$row = $query->row();
echo " and his profileimage is $row->profileimage";
*/
}
else
{
return false;
//echo "no such user as $user!";
}
}
function putProfileImage($username, $img)
{
$record = array('user' => $username, 'profileimage' => $img);
if ($this->exists($username))
{
$this->db->where('user', $username)->update('profileimages', /*'./uploads/.' */$record);
//appends
}
else
{
$this->db->where('user', $username)->insert('profileimages', $record);
}
}
function getProfileImage($username)
{
$this->db->select('*')->from('profileimages')->where('user', $username);
$query = $this->db->get();
if ($query->num_rows() > 0){
$row = $query->row();
return $row->profileimage;
}
return Null;
}
}
Here is my view:
<h3><?="Profile Image"?></h3>
<img src="./web-project-jb/assets/puploads/" width='300' height='300'/>
<?=form_open_multipart('homeprofile/upload');?>
<input type="file" name="userfile" value=""/>
<?=form_submit('submit', 'upload')?>
<?=form_close();?>
<?php if (isset($error)) echo $error;?>
</div>
</div>
I have tried replacing the img src with but I just get an error back saying data is unrecognised
Your view file does not indicate any attempt to output a dynamic image, you have the src
hardcoded and aren't using your $img
variable at all (the one you set in the controller with $data['img']
):
$data['img'] = base_url().'./web-project-jb/assets/puploads/'.$file_data['file_name'];
Here also you seem to be mixing server paths and URLs. Assuming the URL to your uploads folder is:
http://example.com/web-project-jb/assets/puploads/
...use this in your controller (after the upload succeeds):
$data['img'] = 'web-project-jb/assets/puploads/'.$file_data['file_name'];
Then in your view:
<img src="<?php echo base_url($img); ?>" width='300' height='300'/>
