Some please help me with coding the below piece!
So at the moment I have a place where members can set up a profile that displays all there information. I now want to give the user an option to upload images. and have a personal Gallery area.
All the tutorials i seem to find only show me how to do an image upload. And not specific to users that there gallery area will have other peoples work in it.
I assume this will need a database to make it user specific? or work off the $_SESSION variable? I just dont know how to go about doing this.
im totally lost can someone point me in the right direction?
Below is my current gallery.php code which just pretty much generates thumbnails and displays all given images in the uploads folder.
How would I go about editing this just to display images for the user in a session or given user profile?
<?php
if (isset($_GET['img'])){
//make thumbnail
if(file_exists($_GET['img'])){
ignore_user_abort(true);
set_time_limit(120);
ini_set('memory_limit', '512M');
$src_size = getimagesize($_GET['img']);
if ($src_size === false){
die('That does not look like an image.');
}
$thumb_width = 200;
$thumb_height = 150;
if ($src_size['mime'] === 'image/jpeg'){
$src = imagecreatefromjpeg($_GET['img']);
}else if ($src_size['mime'] === 'image/png'){
$src = imagecreatefrompng($_GET['img']);
}else if ($src_size['mime'] === 'image/gif'){
$src = imagecreatefromgif($_GET['img']);
}
$src_aspect = round (($src_size[0] / $src_size[1]), 1);
$thumb_aspect = round(($thumb_width / $thumb_height), 1);
if ($src_aspect < $thumb_aspect){
//higher than thumb
$new_size = array ($thumb_width, ($thumb_width / $src_size[0]) * $src_size[1]);
$src_pos = array (0, (($new_size[1] - $thumb_height) * ($src_size[1] / $new_size[1])) / 2);
}else if ($src_aspect > $thumb_aspect){
// wider than thumb
$new_size = array(($thumb_width / $src_size[1] ) * $src_size[0], $thumb_height);
$src_pos = array((($new_size[0] - $thumb_width) * ($src_size[0] / $new_size[0])) / 2, 0);
}else{
// same shape as thumb
$new_size = array($thumb_width, $thumb_height);
$src_pos = array(0, 0);
}
if ($new_size[0] < 1) $new_size[0] = 1;
if ($new_size[1] < 1) $new_size[1] = 1;
$thumb = imagecreatetruecolor($thumb_width, $thumb_height);
imagecopyresampled($thumb, $src, 0, 0, $src_pos[0], $src_pos[1], $new_size[0], $new_size[1], $src_size[0], $src_size[1]);
if ($src_size['mime'] === 'image/jpeg'){
imagejpeg($thumb, "thumbs/{$_GET[ 'img' ]}");
}else if ($src_size['mime'] === 'image/png'){
imagepng($thumb, "thumbs/{$_GET[ 'img' ]}");
}else if ($src_size['mime'] === 'image/gif'){
imagegif($thumb, "thumbs/{$_GET[ 'img' ]}");
}
header("Location: thumbs/{$_GET[ 'img' ]}");
}
die();
}
if (is_dir('./thumbs') === false){
mkdir('./thumbs', 0744);
}
$images = glob('*.{jpg, jpeg, png, gif}', GLOB_BRACE);
?>
<?php
foreach ($images as $image){
if (file_exists("./thumbs/{image}")){
echo "<a href=\"{$image}\"><img src=\"thumbs/{$image}\" alt=\"{$image}\" /></a>";
}else{
echo "<a href=\"{$image}\"><img src=\"?img={$image}\" alt=\"{$image}\" /></a>";
}
}
?>
