		$imagepath = uploadFile($_FILES['image'], $uploadPath);
		$image = new SimpleImage();
		$image->load($imagepath);
		$image->resize(225,250);
		$resize_rename = $uploadPath.$randomnum._.str_replace(' ', '_', $_FILES['image']['name']);
		$image->save($resize_rename);

		unlink($imagepath); //delete the original file

	    $sql = " INSERT INTO tbl SET
		title	= '".$postData['title']."',

1. as webstyles stated, your script will never work since you have $file substituted for the appropriate $_FILES array..

2. why do you not want to upload a temp image, the image needs to be stored temporarily before it can be modified..

$file and $_files both doing the same job, my issue is make image upload not necessary, so ifa users wishes to upload an image then file uploads and link to file get stored in database but if users selects no image i want image filed in database to be blank and no 23424234_ files get uploaded to my directory. i hope im not confusing you guys>?

dunno but it is being uploaqded, when a user selects an image and submits form the image is uploaded like 34534534_imagename.jpg and it gets saved in DB the same way but if user submits form without image still in DB 234234_ gets saved in image field and a 234234_ file gets created in my image directory. could you please make my code in a better way for i got no idea how to get it fixed. i also need to check file type and restrict also image size. help me out please

Can't you just check against the $_FILES array values if there is image or not? e.g Check against $_FILES['image']['size'] > 0 or check the $_FILES['image']['error'] if it exists etc. in IF condition. And do not save the data in database if everything is not all right. You can see more info about the upload errors here: http://php.net/manual/en/features.file-upload.errors.php .

 

Pseudo

if (image data is good)
{
    // save to db.
}
else
{
    // dont save and show error or something..
}

did this

 

function insertit($postData) {	

if($_FILES['image'] == 1){

		global $uploadPath;
		$randomnum=rand(00000000,99999999);  
		$imagepath = uploadFile($_FILES['image'], $uploadPath);
		$image = new SimpleImage();
		$image->load($imagepath);
		$image->resize(225,250);
		$resize_rename = $uploadPath.$randomnum._.str_replace(' ', '_', $_FILES['image']['name']);
		$image->save($resize_rename);

		unlink($imagepath); //delete the original file

	    $sql = " INSERT INTO tbl SET
		title	= '".$postData['title']."',
		image	= '".$resize_rename."',
		name	= '".$postData['name']."',
		category 	= '".$postData['category']."',
		adtype	= '".$postData['ads_type']."',
		state	= '".$postData['state']."',
		location	= '".$postData['location']."',
		email 	= '".$postData['email']."',

		description	= '".$postData['description']."'
		";
		executeSql($sql);

you want

 

if(!empty($_FILES['image'])){

 

also, is your "uploadfile" function custom?

 

That will not be empty. It will contain error data in case there was no uploaded file. Actually you could do it with is_uploaded_file() like WebStyles mentioned much earlier.

if (is_uploaded_file($_FILES['image']['tmp_name']))
{
    // Save to db
}

my is_uploaded_file is in a function like this

 

function uploadFile($file, $uploadPath) {

 

print 'file name'.$file['name'];

 

if (is_uploaded_file($file['tmp_name']) && $file['error']==0) {

    $path = $uploadPath . $file['name'];

    if (!file_exists($path)) {

if (move_uploaded_file($file['tmp_name'], $path)) {

  echo "The file was uploaded successfully.";

  return $path;

} else {

  echo "The file was not uploaded successfully.";

}

    } else {

echo "File already exists. Please upload another file.";

    }

      } else {

echo "The file was not uploaded successfully.";

echo "(Error Code:" . $file['error'] . ")";

      }

    }

$file_type = array("image/gif","image/jpg","image/png");
$image_type = $_FILES["image"]["type"];
if(in_array($image_type,$file_type)){
   // correct file type
}

 

$max_size = 1048576;
$file_size = $_FILES['image']['size'];
if($file_size > $max_size){
      // too big
}
