PHP - Gallery Photos In Wrong Order

Hi!

I am creating a small project somewhat like a photo gallery as my first practice page. I just would like to know how can I alter photos or file in php. Or should I just do a delete and then upload a new one?

Thanks in advance...

How should I go about keeping track of photos that a user has rated, since I only want the user to rate the photo once? Can I store arrays in a mysql database?

thanks,
George

I have some thousands of photos about nature
I ll let visitors/members to see them one by one,
but I dont want to show them the same photo again after they visit 1 week later

How can I do this ?

What I think as a solution is;
For members;
I can store the ids (like "everest01") of the photos that member has visited , and show user the most visited photos that he/she has not see for next visit. But what I m wondering is, how will I take the photos from DB ?

select * from photos WHERE id not in ( $thousandsofvisitedphotoids ) ??
I m stuck here ?

For visitors ( not members ) ;
I can set a cookie that keeps the ids of visited photos.. when visitor visits the website again, I take the cookie and sent to $thousandsofvisitedphotoids and make a query again ?

I m stuck here, How you guys do this ? what's the logic of this ?

My photo files are not being displayed in my table?

They get sent to the mySQL database, then the server and it does grab all the other variables in the table and displays them, but the .jpg's are not shown, instead theres just the file name??

Code: [Select]
<?php 
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 echo '<pre>' . print_r($_FILES, true) . '</pre>';

 
 //This is the directory where images will be saved 
 $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; 
 $target = $target . basename( $_FILES['upload']['name']); 
 
 //This gets all the other information from the form 
 $company_name=$_POST['company_name']; 
 $basicpackage_description=$_POST['basicpackage_description']; 
 $location=$_POST['location']; 
 $postcode=$_POST['postcode'];
 $upload=($_FILES['upload']['name']); 
 
 // Connects to your Database 
 mysql_connect("server****", "username***", "password****") or die(mysql_error()) ; 
 mysql_select_db("DB") or die(mysql_error()) ; 
 
 //Writes the information to the database 
 mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode,  upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode',  '$upload')") ; 
 echo mysql_error();
 
 //Writes the photo to the server 
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) 
 { 
 
 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 
 
 //Gives and error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 ?>

"upload" is the variable that isnt displaying in my table how i want it to? Have you guys any ideas how to get it displayed correctly?

I have a page for image uploads and I just realized it will only work if a user already has on picture uploaded.
If they don't it won't work.
The ones that do fail some photos anyway which is probably that they don't pass the image check but when I put echoes in there to trace what happens any user with an empty gallery can't upload a photo because the page says there is no file in the $_FILES['image']['name'] variable.

Here are the initial conditions and the form (leaving out the image processing etc since that works):
Code: [Select]
if (!isset($_SESSION['user']))
die("<br /><br /> You need to log in to view this page");

$user = sanitizeString($_SESSION['user']);
$view = sanitizeString($_GET['view']);
$dir = './grafik/users/'.$user.'/big/';
$files = scandir($dir);
$len = count($files);
$nr= $len-1;
$maxPhotos = 8;

if ($view == $user) {
echo "view is user";
if(!file_exists("grafik/users/$user")) {
mkdir("grafik/users/$user");
mkdir("grafik/users/$user/big/");}
}

if (!isset($_FILES['image']['name']))
    echo "There is no file <br />$dir - $user - $nr";
if (isset($_FILES['image']['name'])) {
echo "<br />...is a file <br />$dir - $user - $nr";
$photoName="$dir$user$nr.jpg";
move_uploaded_file($_FILES['image']['tmp_name'], $photoName);
$typeok = TRUE;

....


<form method='post' action='gallery.php?view=$user' enctype='multipart/form-data'>
Upload another photo: <br /> Max $maxPhotos allowed, max filesize 2Mb <br />
<input type='file' name='image' size='10' /><br />
<input type='submit' value='Upload' />
</form>

I can't see why it wouldn't let me but I have a feeling someone here knows why.

I was thinking of a board where you can bookmark the photos from Facebook.   It may require an App and a "Facebook Login" for the website, so one can bookmark photos from Facebook. The website would have additional features for the photos.   I thought of an "Add to ..." function.   Is this possible with the Facebook API?

I have users becoming members and allowed them to upload their own photos. But when they try to upload 5MB photos, it takes time to upload the photo, and sometimes server gives a timeout error.

I have searched and found javascripts that uploads to the server but I have noticed that it has security problems.

So how do you let users to upload photos ?

Hi friends,

I have two mysql db tables, photos and album, I would like to list photos by album how do i do that ?


CREATE TABLE `album` (
 `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
 `album_name` varchar(95) NOT NULL,
 `album_desc` text NOT NULL,
 PRIMARY KEY (`id`)
);



CREATE TABLE `photos` (
 `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
 `album_id` int(11) NOT NULL,
 `thumb_name` varchar(255) NOT NULL,
 `photo_name` varchar(250) NOT NULL,
 PRIMARY KEY (`id`)
)

Does anyone know of a good tutorial on uploading a picture file to a folder using php and copying the name to the database in mysql?  Resizing photos on upload is helpful also...If you know it works...some I have tried do not work.

Not asking for someone to write code for me but info or tutorial would be nice.  Or maybe a code that has worked for you that is similar that I could learn from and edit...

I can upload the actual photo into the database but it slows it way down.  I have heard of loading the name only and resizing the photo and sending the actual photo to a file folder on the server.  The few codes I have tried were not successful. 

Thanks for any guidance.  I appreciate it.

I'm talking like /uploads at the main folder where index.php or index.html goes   These photos theoretically are meant to be publicly viewed anyway so what is bad about that?   Let's say profile pictures.   I mean couldn't anyone scrape facebook and "steal" profile pictures? I don't know why but I'm just wondering.

I need help with my webpage here, how do you get so if you are at http://www.blabla.com/account.php and then click on a photo, it will go to www.blabla.com/photo.php?id=1 but still be at account.php? Just like facebook shows their photos. I dont know how to think nor to get it work. Would appreciate some help!

Hello:

I am trying to figure out how to do an UPDATE SET for a photo gallery based on the "photo_id" ... not working to well ...

Currently, it just uploads a photo but updates everything.

This is the code:
Photo_Edit.php
Code: [Select]
<?php

$photo_id = $_REQUEST['photo_id'];

?>

...


<?php


$query=mysql_query("SELECT * FROM gallery_photos WHERE photo_id = $photo_id") or die("Could not get data from db: ".mysql_error());

while($result=mysql_fetch_array($query))
{
  $photo_id=$result['photo_id'];
  $photo_filename=$result['photo_filename'];
  $photo_caption=$result['photo_caption'];
}

?>

<form enctype="multipart/form-data" action="a_Photo_Upload2.php" method="post" name="upload_form">

<input type='hidden' name='photo_id' value='<?php echo $photo_id; ?>' />

Can anyone show me how to make this work, OR show me a way to do this ...

Thank you.

I am looking at making a photogallery system for an online community based site. I know that we need to have unique id's , photo names and albums.

What i am looking for is:

Would it be recommended to create a directory for each user once they are registerd?
How would you go about naming and sorting photogralleries?
How would you go about naming you photos?
How would you do it?

I was thinking about a uuid kind of code: ( from php.net)

  Code: [Select]
class UUID {
  public static function v3($namespace, $name) {

    // Get hexadecimal components of namespace
    $nhex = str_replace(array('-','{','}'), '', $namespace);

    // Binary Value
    $nstr = '';

    // Convert Namespace UUID to bits
    for($i = 0; $i < strlen($nhex); $i+=2) {
      $nstr .= chr(hexdec($nhex[$i].$nhex[$i+1]));
    }

    // Calculate hash value
    $hash = md5($nstr . $name);

    return sprintf('%08s-%04s-%04x-%04x-%12s',
