PHP - Rating Photos

I've built a database based rating system, and till now everything works as expected except of one minor thing that breaks the while rating system.

When you press thumbs up or down it's only adding the vote to the LAST printed table in the while loop, it does NOT add it to the current table where the button was pressed.

This is the while loop:


<?php 
function knuffix_list ($query, $user_name, $avatar_path, $dbc) {

$data = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc));

//Loop through the array of data

while ($row = mysqli_fetch_array ($data)) {

global $con_id;

$con_id = $row['con_id'];

echo "<table padding='0' margin='0' class='knuffixTable'>";

echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='$avatar_path' alt='avatar' /></td>";

echo "<td class='knuffix_username'><strong>" . $user_name . " ___ ";

echo "</strong><br />" . $row['category'] .  " | " . date('M d, Y', strtotime($row['contributed_date'])) . "</td></tr><tr><td>";

echo "<form action='' method='post'>

<button type='submit' name='plusVote' value='like'>Y</button>

<button type='submit' name='minusVote' value='dislike'>N</button>

<input type='hidden' name='hidden_con_id' value='<?= " . $con_id . " ?>' />

</form></td><td class='votes'>Y[ - ] | N[ - ]</td></tr>";

echo "<tr><td class='knuffix_name' colspan='3'><strong>" . htmlentities($row['name']) . "</strong><br /></td></tr>";

echo "<tr><td colspan='2' class='knuffix_contribution'><pre>" . $row['contribution'] . "</pre><br /></td></tr>";

echo "</table>";

}

mysqli_close($dbc);

}

?>


The con_id is the value how I wanted to determine which table it is, when I echo $con_id out (inside the while loop) it's showcasing the numbers correctly, but it doesn't work with the buttons, the buttons simply correspond to the last printed table in the while loop. I think it's because the while loop goes through each row until it's finished and it stops.

This is the rating script:



// RATING SYSTEM

$plus_vote = $_POST['plusVote'];
$minus_vote = $_POST['minusVote'];


if ($plus_vote || $minus_vote) {

$query = "SELECT * FROM con WHERE con_id = '$con_id'";
$query = mysqli_query ($dbc, $query) or die (mysqli_error($dbc)); 
$assoc_vote = mysqli_fetch_assoc ($query);

if ($plus_vote) {

$vote_up = $assoc_vote['likes'] + 1;

$query = "UPDATE con SET likes = '$vote_up' WHERE con_id = '$con_id'";

$query_run = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); 

mysqli_close($dbc);

echo "test " . $con_id;

} elseif ($minus_vote) {

$vote_down = $assoc_vote['dislikes'] - 1; 

$query = "UPDATE con SET dislikes = '$vote_down' WHERE con_id = '$con_id'";

$query_run = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); 

mysqli_close($dbc);

echo "test " . $con_id;

}
}



If I would be able to make the buttons in the while loop to RECOGNIZE the correct con_id of the table the button was being pressed then the script would work as intended and it would add the vote to the correct row in the table.

How could I solve this problem, because I really have no idea?

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 ?

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...

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.

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?

Hello.  My website has a photo gallery of thumbnails that is created by reading all photo files in a specified directory.

Here is my function that builds the array which is ultimately displayed in the gallery...

	<?php
    function getPhotoFilesArray($photoPath){
        /**
         * Takes path to photo-directory, and returns an array containing photo-filenames.
         */
	    // Initialize Array.
    $photoFiles = array();
	    // Check for Photo-Directory.
    if (is_dir($photoPath)){
      // Photo-Directory Found.
      // Open Directory-Handle.
      $handle = opendir($photoPath);
	      // Open Photo-Directory.
      if($handle){
        // Initialize Key.
        $i = 1001;
	        // Iterate through Photo-Directory items.
        while(($file = readdir($handle)) !== FALSE){
          // Return next Filename in Directory.
          
          // Define fullpath to file/folder.
          $fullPath = $photoPath . $file;
	          // Populate Array.
	          if(!is_dir($fullPath)
              && preg_match("#^[^\.].*$#", $file)){
            // Not Directory.
            // Not Hidden File.
            // Add to array.
            $photoFiles[$i] = $file;
	            $i++;
          }//End of POPULATE ARRAY.
          
        }//End of ITERATE THROUGH PHOTO-DIRECTORY ITEMS
	        closedir($handle);
        
      }//End of OPEN PHOTO-DIRECTORY
	    }else{
      // Photo-Directory Not Found.
      // Redirect to Page-Not-Found.
      header("Location: " . BASE_URL . "/utilities/page-not-found");
	      // End script.
      exit();
	    }//End of CHECK FOR PHOTO-DIRECTORY
	        return $photoFiles;
	    }//End of getPhotoFilesArray
	?>
	

 

Everything works fine locally in DEV, but when I uploaded my website (and photos) onto a webserver, the photos are appearing in a backwards order in PROD.

This is annoying, because I want the photos displayed chronologically from oldest (first) to newest (last).

I'm not sure where the problem is happening, because each photo was taken with my camera and by nature of the camera, photo names are incremented by one, so IMG_001.jpg would have been taken FIRST, followed by IMG_002.jpg, IMG_003.jpg, and so on.

How can I fix things so the photos are displayed in the order they were physically taken AND match how things display locally in DEV?

Thanks!

 

 

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.

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`)
) 

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 ?

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!

I have a php page that creates a photo gallery with thumbnails.  It is populated by code that reads all photo files from a specified photo directory.

This was working fine in DEV, but now that I have uploaded to my test web server, the pictures are in reverse order.

Not the end of the world, yet annoying, because they should be in chronological order.

Files names are straight off my iPhone (e.g. IMG_2203.jpg, IMG_2204.jpg, IMG_2207.jpg)

What is happening, and how can I fix this?

Thanks!

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 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)
