downloading an image

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



tthe image does not display although it exists in the table 'images'


This calls the download script


<?
 $property_id = $_SESSION['property_id'] ;
 $query = "SELECT * FROM images WHERE property_id='$property_id'";
$result = mysql_query($query);
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

echo $id= $row['id'];
echo $title= $row['title'];
$link = "download.php?id=$id";
}
?>
<img src="<?php echo $link; ?>"/>



this is the download script

id = $_GET['id'];
$query = "SELECT name, type, size, content FROM images WHERE id ='$id'";

 $result = mysql_query($query) or die(mysql_error());
list($name, $type, $size, $content) = mysql_fetch_array($result);

header("Content-length: $size");
header("Content-type: $type");

echo $content;

exit;
