[GENERAL] Displaying image from php script displays string

[Alexander Reichstadt]

Sorry if this has been asked a thousand time. I read through the web and think 
to have done everything I should.

I have a db with a bytea field. In it I stored data from a png file. When I 
stored it I used pg_escape_bytea(<CONTENTS OF FILE>) and it seems it ended up 
ok in the database.


I made a test setup, check this out:

http://qmprozesse.aemtervz.de/jdbqm/php/imagetest.html


Here the store script:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

include_once 'classes/dbop.php';


$thePrefName = $_REQUEST['prefkeyname'];
//$theData = $_REQUEST['file'];



if ($_FILES["file"]["error"] > 0)
{
        echo "Error: " . $_FILES["file"]["error"] . "<br />";
        return;
} else {
        echo "Upload: " . $_FILES["file"]["name"] . "<br />";
        echo "Type: " . $_FILES["file"]["type"] . "<br />";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
        echo "Stored in: " . $_FILES["file"]["tmp_name"];
}

$file=fopen($_FILES["file"]["tmp_name"],"r") or exit("Unable to open file!");
$filedata = '';
while (!feof($file))
  {
  $filedata .= fgetc($file);
  }
fclose($file);
$filedata = pg_escape_bytea($filedata);



$query = 'INSERT INTO qmcustomerdata (prefkey,dataval) VALUES(\'' . 
$thePrefName . '\',\'' . $filedata . '\')';
Dbop::singleton()->querydb($query);


?>











Here the script customer_displayimage.php pointed to:
<?php

error_reporting(E_ALL);
ini_set('display_errors', '1');

include_once 'classes/dbop.php';

$query = 'SELECT dataval FROM qmcustomerdata WHERE prefkey=\'' . 
$_REQUEST['prefkey'] . '\'';
$result = Dbop::singleton()->querydb($query);
echo pg_unescape_bytea($result[0]['dataval']);

?>

Here the Dbop and what it's doing:

public function querydb($querystring)
        {
//              echo '<br>DEBUG::' . $querystring . '<br>';
                $dbconnection = pg_connect("host=localhost dbname=xxxxx 
user=xxxxx password=xxxxx")
                        or die('could not connect: ' . pg_last_error());
                $result = pg_query($querystring);
                $ra = array();
                if (pg_num_rows($result)){
                        $ra = pg_fetch_all($result);
                }
        pg_free_result($result);                
                pg_close($dbconnection);

                return $ra;
        }



What am I doing wrong?

Thanks
Alex
