Help with Output image

[eluser]toopay[/eluser]

Code:

$imagepath = str_replace(chr(92),'/',$_SERVER["DOCUMENT_ROOT"]).'/test/'.$imagepath;

As you can see, the problems is you are try to access invalid file, thats why it generates errors. Work around with above code.

yes sorry .. here is the code i have :

Code:

public function showpic()
    {
        $idpic = $this->uri->segment(3);
        $this->db->where('id',$idpic);
        foreach($this->db->get('account_gallery')->result() as $row)
        {
            $photo = $row->thumb;    
        }        
        $imagepath = 'test/gallery/'.$this->session->userdata('nickname').'/thumbs/'.$photo;
        $imagepath = str_replace(chr(92),'/',$_SERVER["DOCUMENT_ROOT"]).'/'.$imagepath;
        //var_dump($imagepath); exit;

        if (file_exists($imagepath))
        {
            $this->output->set_content_type('jpeg');
            $this->output->set_header('Content-Type: image/jpeg');
            $this->output->set_output(file_get_contents($imagepath));
        }
        else
        {
           echo 'Invalid image path';
        }    
    }

and it doesn't work .. here is the path i get :

Code:

string(67) "C:/inetpub/wwwroot/test/gallery/nick/thumbs/_MAG0921_thumb.jpg"

And with this path i get no image and no errors

What if you put that path directly into your browser? Is that generates the right image?

Yes if i put the path directly in the browser i get the right image.
The problem is that i can't get it working with codeigniter

Okey, this started sound UNBELIEVABLE, just make sure the file is exist, do this...

Code:

if (file_exists($imagepath))
{
    var_dump(file_get_contents($imagepath));
    /*
    $this->output->set_content_type('jpeg');
    $this->output->set_header('Content-Type: image/jpeg');
    $this->output->set_output(file_get_contents($imagepath));
    */
}

Unbelievable is the right word ... i'm going crazy with this problem.

The file exist .. because with your code i get something like :

Code:

string(4658) "ÿØÿàJFIFÿþ;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90 ÿÛC     ÿÛC          ÿÀxx"ÿÄ     ÿĵ}!1AQa"q2‘¡#B±ÁRÑð$3br‚     %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyzƒ„…†‡ˆ‰Š’“”•–—˜™š¢£¤¥¦§¨©ª²³´µ¶·¸¹ºÂÃÄÅÆÇÈÉÊÒÓÔÕÖ×ØÙÚáâãäåæçèéêñòóôõö÷øùúÿÄ     ÿĵw!1AQaq"2B‘¡±Á    #3RðbrÑ $4á%ñ&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvw

p.s. of course i had to cut the whole content of the page because it was huge

So the file exist and the path seems to be absolutely correct

What if you send the response manually :

Code:

// Uncomment var_dump, and replace with this...
header('Content-Type: image/jpeg');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '. filesize($imagepath));
readfile($imagepath);

still nothing ... am i missing some library or helper ?
I don't even get any error so i really don't know how to solve ..

I dont have IIS server installed here, but i suspect thats the problems. In Apache, $_SERVER['DOCUMENT_ROOT'] should give you the right path of your application directory, and there is no need to include 'test' or doing some string replacement ('\' to '/'). Do you have Apache installed on your computer for compare?

I've just tried to upload everything in my test server (Linux + Apache + MySQL).

I always don't get anything in the output.
Of course if i try to dump the image with "var_dump" i get the content of the image.

That's crazy for me ...
