I have a simple registration form, in which I accept inputs from the user that includes an image, and insert the values in a table : temporary_employees table . In my code, I check whether the email id and the user id entered by the user already exists and if they dont , i go ahead and perform the insert after moving the image to a folder named 'images' . While running the code , I am getting an error Undefined index: image, on the line where I have the following piece of code :
$target_file = $target_path . basename ($_FILES['image']['name']);
The most interesting thing is the same line of code has worked perfectly well in another php file . I had given the same name for the input in the html form . . How is it possible ? Any help will be appreciated .
Here is my code :
//start the session before anything is echoed to the browser
if (session_status()===PHP_SESSION_NONE) {
session_start();
}
