I’ve just been playing around with exception handling for form processing
This works fine:
if(isset($_POST['submit'])) {
$error = array();
if(empty($_POST['title'])) {
$error[] = "Opps, you forgot to give the article a title!";
}
if(empty($_POST['body'])) {
$error[] = "Opps, you forgot to write the article!";
}
if($_POST['select'] === "choice") {
$error[] = "Opps, you forgot to pick a category";
}
if(empty($_POST['publish']) && empty($_POST['not-publish'])) {
$error[] = "Opps, you forgot to state whether you would like to publish the article or not!";
}
foreach($error as $error_message) {
echo $error_message . br;
}
}
But with exception handling it doesn’t do anything at all! What have I misunderstood about this OOP PHP code?
if(isset($_POST['submit'])) {
try {
if(empty($_POST['title'])) {
throw new Exception("Opps, you forgot to give the article a title");
}
if(empty($_POST['body'])) {
throw new Exception("Opps, you forgot to write the article!");
}
if($_POST['select'] === "choice") {
throw new Exception("Opps, you forgot to pick a category!");
}
if(empty($_POST['publish']) && empty($_POST['not-publish'])) {
throw new Exception("Opps, you forgot to pick a category!");
}
echo "Everything is working okay!";
}
catch (Exception $e) {
$result = '<p>There has been a problem with the form</p>';
$result .= br;
$result .= '<p>' . $e->getMessage() . '</p>';
}
}
