Gallery directory source help please :)

joeysnacks · February 2, 2012

Hi Everyone, I am a noob so forgive me I tried looking this up myself But I am still confused.

Basically, I am trying to use the above code to display a gallery of images from my images folder on my image site.

But this free code I found below Pulls the images from the /root not a named directory where the images are stored.

Would someone be kind enough to tell me how I can get the script below to pull the large images from a folder called "images" Vs the script looking for the images the root.

Thanks so much in advance :shy:

<?php
# SETTINGS
$max_width = 100;
$max_height = 100;

function getPictureType($ext) {
	if ( preg_match('/jpg|jpeg/i', $ext) ) {
		return 'jpg';
	} else if ( preg_match('/png/i', $ext) ) {
		return 'png';
	} else if ( preg_match('/gif/i', $ext) ) {
		return 'gif';
	} else {
		return '';
	}
}

function getPictures() {
	global $max_width, $max_height;
	if ( $handle = opendir(".") ) {
		$lightbox = rand();
		echo '<ul id="pictures">';
		while ( ($file = readdir($handle)) !== false ) {
			if ( !is_dir($file) ) {
				$split = explode('.', $file); 
				$ext = $split[count($split) - 1];
				if ( ($type = getPictureType($ext)) == '' ) {
					continue;
				}
				if ( ! is_dir('thumbs') ) {
					mkdir('thumbs');
				}
				if ( ! file_exists('thumbs/'.$file) ) {
					if ( $type == 'jpg' ) {
						$src = imagecreatefromjpeg($file);
					} else if ( $type == 'png' ) {
						$src = imagecreatefrompng($file);
					} else if ( $type == 'gif' ) {
						$src = imagecreatefromgif($file);
					}
					if ( ($oldW = imagesx($src)) < ($oldH = imagesy($src)) ) {
						$newW = $oldW * ($max_width / $oldH);
						$newH = $max_height;
					} else {
						$newW = $max_width;
						$newH = $oldH * ($max_height / $oldW);
					}
					$new = imagecreatetruecolor($newW, $newH);
					imagecopyresampled($new, $src, 0, 0, 0, 0, $newW, $newH, $oldW, $oldH);
					if ( $type == 'jpg' ) {
						imagejpeg($new, 'thumbs/'.$file);
					} else if ( $type == 'png' ) {
						imagepng($new, 'thumbs/'.$file);
					} else if ( $type == 'gif' ) {
						imagegif($new, 'thumbs/'.$file);
					}
					imagedestroy($new);
					imagedestroy($src);
				}
				echo '<li><a href="'.$file.'" rel="lightbox['.$lightbox.']">';
				echo '<img src="thumbs/'.$file.'" alt="" />';
				echo '</a></li>';
			}
		}
		echo '</ul>';
	}
}

Change the function getPictures() to take a parameter for the folder to search. Then change the opendir() call to use that parameter

	function getPictures($source_folder) {
	global $max_width, $max_height;
	if ( $handle = opendir($source_folder) ) {

Now just call the function with the path of the imaged in the function call.

<?php getPictures('path/to/images/'); ?>

However, I think glob() would be a much better choice instead of opendir() but I'm not going to rewrite that script.

Thanks so much, for the fast response

I will take your suggestion and look for some code with the glob() instead

I am just trying to basically display and resize pictures from a folder using the GD. nothing crazy

Just kinda new to this
