@$file = $_FILES['image']['tmp_name'];
@$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name = addslashes($_FILES['image']['name']);
@$image_size = getimagesize($_FILES['image']['tmp_name']);
$user_post = $_POST['string']
$user_post is mandatory for proceeding while, image uploading is not compulsory to proceed further, i have tried various methods but
$image_size === falsetakes into account an empty image file and also the wrong image file being upload. I cant check if the image selected is empty or the image file selected is incorrect separately.
Does anyone have a solution for this issue?
If your image upload is optionally and you want to check if the user has uploaded an image or not you can use the array part $_FILES['image']['error'] this part gives you the errorcode of the file.
When this part has the value 4 then no file has been uploade. You can check for that, when moving the file.
