Display all images from outside web root folder using PHP
- by micmola
Hello,
I want to display all images that are stored outside my web root folder. Please help me. I am only able to display one image repeatedly. For example, if I have 5 images in my folder, only one image is displayed on my browser 5 times. Please help me on this. I've been working on this problem for over a month now. I'm a newbie. Help. Thank you. Here is the code I'm using.
images.php
<?php
// Get our database connector
require("includes/copta.php");
// Grab the data from our people table
$sql = "select * from people";
$result = mysql_query($sql) or die ("Could not access DB: " . mysql_error());
$imgLocation = " /uploadfile/";
while ($row = mysql_fetch_array($result))
{
$imgName = $row["filename"];
$imgPath = $imgLocation . $imgName;
echo "<img src=\"call_images.php?imgPath=" . $imgName . "\" alt=\"\"><br/>";
echo $row['id'] . " " . $imgName. "<br />";
}
?>
call_images.php
<?php
// Get our database connector
require("includes/copta.php");
$imgLocation = '/ uploadz/';
$sql = "select * from people";
$result = mysql_query($sql) or
die ("Could not access DB: " . mysql_error());
while ($row = mysql_fetch_array($result)) {
$imgName = $row["filename"];
$imgPath = $imgLocation . $imgName;
// Make sure the file exists
if(!file_exists($imgPath) || !is_file($imgPath)) {
header('HTTP/1.0 404 Not Found');
die('The file does not exist');
}
// Make sure the file is an image
$imgData = getimagesize($imgPath);
if(!$imgData) {
header('HTTP/1.0 403 Forbidden');
die('The file you requested is not an image.');
}
// Set the appropriate content-type
// and provide the content-length.
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: image/jpg");
header("Content-length: " . filesize($imgPath));
// Print the image data
readfile($imgPath);
exit();
}
?>
