J'ai un site internet d'images dont j'aimerais que le formulaire accepte les animations, les .swf. Vu qu'il y'a plusieurs niveaux de contrôles, je ne sais pas trop ou se trouve le problème.
Voici le traitement du formulaire :
if(isset($_POST['submit']))
{
$image = new image();
$uploaded_image = false;
$parent = '';
$error = '';
if(empty($_FILES['upload']) && isset($_POST['source']) && $_POST['source'] != "" && substr($_POST['source'],0,4) == "http" || $_FILES['upload']['error'] != 0 && isset($_POST['source']) && $_POST['source'] != "" && substr($_POST['source'],0,4) == "http")
{
$iinfo = $image->getremoteimage($_POST['source']);
if($iinfo === false)
$error = $image->geterror()."<br />Could not add the image.";
else
$uploaded_image = true;
}
else if(!empty($_FILES['upload']) && $_FILES['upload']['error'] == 0)
{
$iinfo = $image->process_upload($_FILES['upload']);
if($iinfo === false)
$error = $image->geterror()."<br /> An error occured. The image could not be added because it already exists or it is corrupted.";
else
$uploaded_image = true;
}
else
{
print "No image given for upload.";
}
if($uploaded_image == true)
{
$iinfo = explode(":",$iinfo);
$tclass = new tag();
$misc = new misc();
$ext = strtolower(substr($iinfo[1],-4,10000));
$source = mysql_real_escape_string($_POST['source']);
$title = mysql_real_escape_string($_POST['title']);
$tags = strtolower(mysql_real_escape_string(str_replace('%','',str_replace("'","'",str_replace('"','"',$_POST['tags'])))));
$tags = strip_tags($tags);
$ttags = explode(" ",$tags);
$tag_count = count($ttags);
if($tag_count == 0)
$ttags[] = "tagme";
if($tag_count < 5 && strpos($ttags,"tagme") === false)
$ttags[] = "tagme";
foreach($ttags as $current)
{
if(strpos($current,'parent:') !== false)
{
$parent = str_replace("parent:","",$current);
if(!is_numeric($parent))
{
//messed up parent id, removing...
$parent = '';
}
$current = '';
}
if($current != "" && $current != " ")
{
$ttags = $tclass->filter_tags($tags,$current, $ttags);
$alias = $tclass->alias($current);
if($alias !== false)
{
$key_array = array_keys($ttags, $current);
foreach($key_array as $key)
{
$ttags[$key] = $alias;
}
}
}
}
$tags = implode(" ",$ttags);
foreach($ttags as $current)
{
if($current != "" && $current != " ")
{
$ttags = $tclass->filter_tags($tags,$current, $ttags);
$tclass->addindextag($current);
$cache = new cache();
if(is_dir("$main_cache_dir".""."\search_cache/".$misc->windows_filename_fix($current)."/"))
$cache->destroy_page_cache("search_cache/".$misc->windows_filename_fix($current)."/");
}
}
asort($ttags);
$tags = implode(" ",$ttags);
if(substr($tags,0,1) != " ")
$tags = " $tags";
if(substr($tags,-1,1) != " ")
$tags = "$tags ";
$rating = mysql_real_escape_string($_POST['rating']);
if($rating == "e")
$rating = "Explicit";
else if($rating == "q")
$rating = "Questionable";
else
$rating = "Safe";
if(isset($_SESSION['id']) && $_SESSION['id'] != "" && isset($_SESSION['login_session']) && $_SESSION['login_session'] != "")
{
$query = "SELECT user FROM $user_table WHERE id='".mysql_real_escape_string($_SESSION['id'])."' AND login_session='".mysql_real_escape_string($_SESSION['login_session'])."'";
$result = mysql_query($query);
$row = mysql_fetch_assoc($result);
$user = $row['user'];
}
else
{
$user = "Anonymous";
}
if(isset($_SERVER['HTTP_X_FORWARD_FOR']))
$ip = mysql_real_escape_string($_SERVER['HTTP_X_FORWARD_FOR']);
else
$ip = mysql_real_escape_string($_SERVER['REMOTE_ADDR']);
$isinfo = getimagesize("./images/".$iinfo[0]."/".$iinfo[1]);
$query = "INSERT INTO $post_table(creation_date, hash, image, title, owner, height, width, ext, rating, local_copy, tags, directory, source, active_date, ip) VALUES(NOW(), '".md5_file("./images/".$iinfo[0]."/".$iinfo[1])."', '".$iinfo[1]."', '$title', '$user', '".$isinfo[1]."', '".$isinfo[0]."', '$ext', '$rating', TRUE, '$tags', '".$iinfo[0]."', '$source', '".date("Ymd")."', '$ip')";
if(!is_dir("$main_cache_dir".""."\thumbnails/".$iinfo[0]."/"))
$image->makethumbnailfolder($iinfo[0]);
$image->thumbnail($iinfo[0]."/".$iinfo[1]);
if(!mysql_query($query))
{
print "failed to upload image.";
unlink("./images/".$iinfo[0]."/".$iinfo[1]);
$image->folder_index_decrement($iinfo[0]);
$ttags = explode(" ",$tags);
foreach($ttags as $current)
{
$tclass->deleteindextag($current);
}
}
else
{
$query = "SELECT id FROM $post_table WHERE hash='".md5_file('./images/'.$iinfo[0]."/".$iinfo[1])."' AND image='".$iinfo[1]."' AND directory='".$iinfo[0]."' LIMIT 1";
$result = mysql_query($query);

$cache = new cache();
if($parent != '' && is_numeric($parent))
{
$parent_check = "SELECT COUNT(*) FROM $post_table WHERE id='$parent'";
$pres = mysql_query($parent_check);
$prow = mysql_fetch_assoc($pres);
if($prow['COUNT(*)'] > 0)
{
$temp = "INSERT INTO $parent_child_table(parent,child) VALUES('$parent','".$row['id']."')";
mysql_query($temp);
$temp = "UPDATE $post_table SET parent='$parent' WHERE id='".$row['id']."'";
mysql_query($temp);
$cache->destroy("cache/".$parent."/post.cache");
}
}
if(is_dir("$main_cache_dir".""."cache/".$row['id']))
$cache->destroy_page_cache("cache/".$row['id']);
$query = "SELECT id FROM $post_table WHERE id < ".$row['id']." ORDER BY id DESC LIMIT 1";
$result = mysql_query($query);
$row = mysql_fetch_assoc($result);
$cache->destroy_page_cache("cache/".$row['id']);
$query = "UPDATE $post_count_table SET last_update='20060101' WHERE access_key='posts'";
mysql_query($query);
print "Image added.";
}
}Et voici le traitement de l'upload, comme vous le voyez il y'a plusieurs renvois de false, difficile de savoir lequel renvoie false.
function process_upload($upload)
{
global $min_upload_width, $min_upload_height, $max_upload_width, $max_upload_height;
if($upload == "")
return false;
$ext = explode('.',$upload['name']);
$count = count($ext);
$ext = $ext[$count-1];
$ext = strtolower($ext);
if($ext != "jpg" && $ext != "jpeg" && $ext != "gif" && $ext != "png" && $ext != "bmp" && $ext != "swf")
return false;
$ext = ".".$ext;
$fname = hash('sha1',hash('md5',$upload['name']));
move_uploaded_file($upload['tmp_name'],"./tmp/".$fname.$ext);
$f = fopen("./tmp/".$fname.$ext,"rb");
if($f == "")
return false;
$data = '';
while(!feof($f))
{
$data .= fread($f,4096);
}
fclose($f);
if(preg_match("#<script|<html|<head|<title|<body|<pre|<table|<a\s+href|<img|<plaintext#si", $data) == 1)
{
unlink("./tmp/".$fname.$ext);
return false;
}
$iinfo = getimagesize("./tmp/".$fname.$ext);
if(substr($iinfo['mime'],0,5) != "image" || $iinfo[0] < $min_upload_width && $min_upload_width != 0 || $iinfo[0] > $max_upload_width && $max_upload_width != 0 || $iinfo[1] < $min_upload_height && $min_upload_height != 0 || $iinfo[1] > $max_upload_height && $max_upload_height != 0 || !$this->checksum("./tmp/".$fname.$ext))
{
unlink("./tmp/".$fname.$ext);
return false;
}
$ffname = $fname;
$cdir = $this->getcurrentfolder();
$i = 0;
if(!is_dir("./images/".$cdir."/"))
$this->makefolder($cdir);
while(file_exists("./images/".$cdir."/".$fname.$ext))
{
$i++;
$fname = hash('sha1',hash('md5',$fname.$i));
}
$f = fopen("./images/".$cdir."/".$fname.$ext,"w");
if($f == "")
return false;
fwrite($f,$data);
fclose($f);
$this->folder_index_increment($cdir);
unlink("./tmp/".$ffname.$ext);
return $cdir.":".$fname.$ext;
}A noter que l'erreur que j'obtiens est : "An error occured. The image could not be added because it already exists or it is corrupted", soit false.
Comment contourner cela et faire en sorte que le formulaire accepte aussi les swf ? D'avance merci.
