Check if specific input file is empty
You can check if there is a value, and if the image is valid by doing the following:
if(empty($_FILES['cover_image']['tmp_name']) || !is_uploaded_file($_FILES['cover_image']['tmp_name']))
{
// Handle no image here...
}
Method 1
if($_FILES['cover_image']['name'] == "") {
// No file was selected for upload, your (re)action goes here
}
Method 2
if($_FILES['cover_image']['size'] == 0) {
// No file was selected for upload, your (re)action goes here
}
You can check by using the size
field on the $_FILES
array like so:
if ($_FILES['cover_image']['size'] == 0 && $_FILES['cover_image']['error'] == 0)
{
// cover_image is empty (and not an error)
}
(I also check error
here because it may be 0
if something went wrong. I wouldn't use name
for this check since that can be overridden)
if (empty($_FILES['cover_image']['name']))
