Open directory get images, and display

[peranha]

I want to open a directory, and get all the images in that folder and display them to the webpage  No databse, just a directory of pics.  Here is what I have.

 

getimage.php page.

<?php
$path = "C:/pics";
//images them dir
//$patha ="C:/pics";  
$dh = opendir($path);
while ($file = readdir($dh)) {
if($file != "." && $file != "..") {
	$extension = substr($path, -3); 
	if($extension == "jpg" || $extension == "jpeg"){ 
		header("Content-type: image/jpeg"); 
	}elseif($extension == "gif"){ 
		header("Content-type: image/gif"); 
	}elseif($extension == "bmp"){
		header("Content-type: image/bmp");
	}
	$path = "$path/$file";
	readfile($path);
}
}
closedir($dh); // close dir
?>

 

Here is how it is called on the page.

 

images1.php

<?php
echo "<img src='getimage.php' alt='' width=100 />";
?>

 

Currently it gets the first image in the directory, but every image after that, it adds the first image file name to the $path variable.

 

example

img1 = P3140722.JPG

img2 = P3140722.JPG/P3140723.JPG

img3 = P3140722.JPG/P3140723.JPG/P3140724.JPG

etc....

 

Any ideas?

Here is something that I use to display all the pictures from a folder on my server. Hope this helps. Just change the $imgPath to what your folder configuration is, and change to picture extensions if you want

<?php 
$imgPath = "userimages/Computers";
foreach(glob("$imgPath/{*.jpg,*.png,*.gif}", GLOB_BRACE) as $fname)
{
echo '<img src="' . $imgPath . '/' . baseName($fname) . '" width="150" border="1"><br/><br/>'; 
}
?>

While is a loop. You're storing $path/$file back into $path each time it loops back over but not resetting $path back to it's original value. Which explains why it just keeps adding $file to the end of $path.

 

To fix this, either reset $path or create another variable for storing the full path:

 

Resetting path:
$path = "$path/$file";
readfile($path);
$path = "C:/pics";

Using new variable:
$full_path = "$path/$file";
readfile($full_path);

 

Or don't even set $path in the while loop and put the $path/$file directly in readfile:

 

replace:
$path = "$path/$file";
readfile($path);

with:
readfile("$path/$file");
