PHP - photo gallery upload problem
I found this example code of an image gallery that connects to a mysql database. I am trying to use the add a photo portion. I tested the database connection separately and it is fine. For some reason the page just does not trigger the form action. If I change a table field name it does not throw an error. The built in error message also does not display an error. The page refreshes with no errors and no images are uploaded. The only time I see the image is when I select it and then it appears in the image preview section. Any help is appreciated.

Hi, You have some function which you haven't post here like:
$newpicfile = createthumb($filename,$quality);// Now we create a thumbnail. So we have later, when we look at the pics, less traffic
$newpicdatahex = gethex($newpicfile); //make the hex of the thumb
@unlink($newpicfile);
Here is the include file
<?php
//config entries
$thumbsperline = "4"; //how many thumbnails per line? (if you enter 0 there is 1 thumb per line, if you enter 1 there are 2 etc)
$thumbsperpage = "5";
$quality = "100"; //the jpeg compression factor of a thumbnail (100 = best)
$titleheader = "Picbase - Store pics in a database";
$footer = '<p class="copyright">.:Picbase - Version 2.3 - Store pics in a database - </p>';
//Login informations forr the database
$db_server = "localhost";
$db_login = "root";
$db_password = "root";
$db_name = "dbpic";
$db_table = "picbase";
function createthumb($filename,$thumbqual) {
$size=getimagesize($filename);
$width=$size[0];
$height=$size[1];
$newwidth=100;
$newheight=intval($height*$newwidth/$width);
$oldpic=ImageCreateFromJPEG($filename);
$newpic=ImageCreate($newwidth,$newheight);
ImageCopyResized($newpic,$oldpic,0,0,0,0,$newwidth,$newheight,$width,$height);
$newpicdata = ImageJPEG($newpic,"temp.jpg",$thumbqual); //save it as a tempfile
$newpicfile = "temp.jpg";
return $newpicfile;
}
function connect_database() {
global $db_server, $db_login, $db_password;
$db_connection=@mysql_connect($db_server, $db_login, $db_password);
if(! $db_connection){
die("Error when connecting the database. Please check your login information!");
}
return $db_connection;
}
//convert hex data to bin data
function hex2bin($data) {
$len = strlen($data);
return pack("H" . $len, $data);
}
//make of a timestamp a normal date
function datumwandler($t) {
return sprintf("%02d.%02d.%04d/%02d:%02d:%02d", substr($t, 6, 2), substr($t, 4, 2),substr($t, 0, 4), substr($t,8,2), substr($t,10,2), substr($t,12,2));
}
//we prepare the values for the database
function prepare($value,$tagsallow) {
$value = stripcslashes($value);
$value = str_replace(chr(34),""",$value); //replace " with quot
$value = str_replace(chr(39),"’",$value); //replae '
if($tagsallow == "yes") {
$value = strip_tags($value);
}else{
$value = strip_tags($value,"<a><b><i><u><br><p><img>");
}
return $value;
}
function gethex($file) {
$fp = fopen ($file, "rb"); //we open the pic
$data = fread ($fp, filesize ($file)); //red all
fclose($fp); //close it
$datahex = bin2hex($data); //convert the binary data of the pic in hex data
return $datahex;
}
?>
Here is the db script
CREATE TABLE `picbase` (
`id` int(11) NOT NULL auto_increment,
`who` text NOT NULL,
`descr` text NOT NULL,
`autor` text NOT NULL,
`stamp` timestamp(14) NOT NULL,
`pic` mediumblob NOT NULL,
`thumb` blob NOT NULL,
`pw` text NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE = MYISAM;
Looks like your problem lies with line 33 and 34:
Another evidence: the parse_url() function returns an array (in this case) which when printed looks like this: Array ( [path] => action=add ).
Does all this make sense?
$query = getenv("QUERY_STRING");
parse_url($query);
$action = $_GET['action'];
