Question

PHP MySql Picture Upload Script

Asked by: mimoser

The coding below is to allow members of my site the oppertunity to upload 12 pictures to thier profile. It did work well, for the first few days, now it's telling every member that they have reached there upload limit, even though they havn't uploaded any at all.

Please help, I can't see why it worked and then stopped, when no coding was changed.

$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); 
mysql_select_db($db) or die ("Unable to select database!"); 
$user_id = $_GET['user_id'];
$res = mysql_query("select count(*) from gallery_photos WHERE user_id = '$user_id'");
if(!$res) die(mysql_error());
$count = mysql_result($res,0);
if($count >= 12) {
  echo "You Have Reached Your Twelve Picture Limit";
  ?>
  To Delete Pics <a href="code.php?user_id=<?php echo $user_id; ?>">Click Here</a> 
  <?php
} else {
  	$photo_upload_fields = "";
	$counter = 1;
	$number_of_fields = 3; 
	if( $_GET['number_of_fields'] )
	$number_of_fields = (int)($_GET['number_of_fields']);
	$result = mysql_query( "SELECT category_id,category_name FROM gallery_category" );
	while( $row = mysql_fetch_array( $result ) )
	{
$photo_category_list .=<<<__HTML_END

I take it you have user's table and user_id is the primary key for that table?

Have you queried the database directly to see what the result is?

by: mimoserPosted on 2009-09-11 at 17:11:19ID: 25314453

I have not queried the database, as I not sure what I would need to do. My tables setup is below

photo_id - index
photo_name
photo_caption
photo_catagory
user_id

Its setup so the same user_id can be in up to 12 times like
photo_id = 105
photo_filename = 105.jpg
photo_caption = new pic
photo_catagory = 0
user_id = 23

kind of like that.
Here is also my uplaod page, maybe the problem is in there

upload.php
 
$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); 
mysql_select_db($db) or die ("Unable to select database!");

} else {

I am reviewing your code just now and have just noticed in the upload page you have restricted the number of photos to 10.

Could user's have reached this limit or have they not been able to upload at all?

if($count >= 10) {
  echo "You have reached your twelve picture limit";
} else {

not at all, it automatically tells them they have reached the limit, even if they have not uploaded.

by: christophermccannPosted on 2009-09-11 at 17:30:11ID: 25314506

can you echo $count just after you fetch it i.e. after $count = mysql_result($res,0); and let me know the result please.

can i suggest you create another php file to test and run the following code and see if the table has any rows already in it.

have you also checked to ensure the $_GET value in the URL is the correct user id?

<?php
     $queryResult = mysql_query("SELECT photo_id, user_id FROM gallery_photos", $connection);
 
     while($rows = mysql_fetch_assoc($queryResult))
     {
          echo "PhotoID - " . $rows['photo_id'] . " UserID - " . $rows['user_id'];
     }
?>
