Image upload script + thumbnail

Hi,

I'm already looking for a long time now to get a special script. There are the functions that the script must have:

• Upload an image (jpg or gif) and save it to an images folder on my server.
• As soon as the image has been uploaded, there must be a thumbnail created (120x90) of that picture and saved into the images/thumbs folder.
• Optional: The image name and thumbnail name must be saved into my MySQL database (just as text so I can simple call back the names in my other script).

If someone can help me with a script like this, please post it here! I really need this, but can't make it myself
If you have an uploadscript + thumbnail generator, but not with the MySQL function, then it's ok too. I'll try and figure it out myself then.

Thank you very much!!

 

ok dude, this is a small project that i did, i guess its just what you want. ill put up parts of the code so u can assemeble it, ok

--Start php--
// 4.2 Upload an image

$uploadSuccess = false;
$hasErrors = false;
$message = "";
$sImagePath = "";
$showUploadForm = true;

if($_POST["action"] == "Upload Image")
{
// get album name from album id
$albumName = "";
$sql = "SELECT * FROM gallery_album WHERE albid = '".$_POST['in_album']."'";
$res = mysql_query($sql,$con);
if($res){
$row = mysql_fetch_row($res);
$albumName = $row[1];
}
$albumPath = "albums/$albumName/"; // replace with the folder u need
$thumbPath = $albumPath."thumbs/"; // thumbnail directory

unset($imagename);

if(!isset($_FILES) && isset($HTTP_POST_FILES)) $_FILES = $HTTP_POST_FILES;
if(!isset($_FILES['image_file'])) $error["image_file"] = "An image was not found.";

$imagename = basename($_FILES['image_file']['name']);
// echo $imagename;

if(empty($error))
{
switch($_FILES["image_file"]["type"])

case "image/png" :

case "image/pjpeg": $source = imagecreatefromjpeg($_FILES["image_file"]["tmp_name"]); break;
case "image/gif" : $source = imagecreatefromgif($_FILES["image_file"]["tmp_name"]); break;
}

$newimage = $albumPath.$imagename;
$result = @move_uploaded_file($_FILES['image_file']['tmp_name'], $newimage);
if(empty($result))
$error["result"] = "There was an error moving the uploaded file.";
else
{
// success
$sql = "INSERT INTO `album_image` (`parent_album` , `image_title` )VALUES ('".$_POST["in_album"]
."', '".basename($_FILES["image_file"]["name"])."');";

$res = mysql_query($sql,$con);

if($res) $uploadSucess = true;
else {$hasErrors = true; $message = "Error Uploading the image";}
}

// Create Thumbnail

switch($_FILES["image_file"]["type"])

}
// $src_img = imagecreatefromjpeg($albumPath.basename($_FILES["image_file"]["name"]));
$maxWidth = 150;
$maxHeight = 150;

list($width, $height, $type, $attr)=getimagesize($albumPath.basename($_FILES["image_file"]["name"]));
$xRatio = $maxWidth / $width;
$yRatio = $maxHeight / $height;
if ( ($width <= $maxWidth) && ($height <= $maxHeight) ) {
$newwidth = $width;
$newheight = $height;
}
else if (($xRatio * $height) < $maxHeight) {
$newheight = ceil($xRatio * $height);
$newwidth = $maxWidth;
}
else {
$newwidth = ceil($yRatio * $width);
$newheight = $maxHeight;
}

$dst_img = imagecreate($newwidth,$newheight);
imagecopyresized($dst_img,$src_img,0,0,0,0,$newwidth,$newheight,imagesx($src_img),imagesy($src_img));

imagejpeg($dst_img, $thumbPath.basename($_FILES["image_file"]["name"]));
//
}

hope this is useful to you....

 

Thank you for your reply midhunhk!
I'll try it out immediately

 

I have a script I wrote once, actually it is a full site:

Peace,

 

I have tried your userdemo and it seems that the thumbnail function doesn't work.

this is one i use,its to update images from the database
if u want to insert ,change only the sql statement to insert and
$image_name=$row_Recordset1['home_img']; to
$image_name=time().".jpg"; just to give the images name

<?
//define a maxim size for the uploaded images in Kb

         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)  
//and it will be changed to 1 if an errro occures.  
//If the error occures the file will not be uploaded.
 $errors=0;
//checks if the form has been submitted
 if(isset($_POST['Submit1'])) 
 {
 	//reads the name of the file the user submitted for uploading

	//otherwise we will do more tests
