When I submit empty fields, it displays "Something has gone wrong" instead of "All fields are required.". Could you help me to find my mistake please.
PHP file:
<?php
if(!isset($_POST['name']) ||
!isset($_POST['email']) ||
!isset($_POST['order'])) {
$data = array(
'message' => "All fields are required."
);
echo json_encode($data);
}
?>
You conditions in PHP file are wrong. Use this instead
if(isset($_POST['name']) && isset($_POST['email']) && isset($_POST['order'])) {
$data = array('message' => "Message A");
echo json_encode($data);
}else{
$data = array('message' => "All fields are required");
echo json_encode($data);
}
I use && for required values. You can use && or || according to your need.
Update
if(!isset($_POST['name']) || !isset($_POST['email']) || !isset($_POST['order'])) {
$data = array('message' => "All fields are required");
echo json_encode($data);
}else{
// whatever you want to do, if all values available, goes here
}
empty() does two things. It not only checks if the key exists in $_POST or $_GET but it also checks if it contains a value or not, keep in mind that it considers 0 as empty. isset() only checks if the key exists.Try this:
<?php
if(!isset($_POST['name']) || !isset($_POST['email']) || !isset($_POST['order'])) {
echo "No post values found!";
}
else{
$data = array('message' => "Message A");
echo json_encode($data);
}
?>
Instead of using !isset() try using empty().
