[@Mr.samomar]

I was get problem Here 24:09 When I use same Email, It's not only show the error massage It will break the code.
Then I used try catch to solve the problem.
try {
$sql = "INSERT INTO clients (name, email, phone, address) VALUES ('$name', '$email', '$phone', '$address')";
$result = $connection->query($sql);
} catch (\Exception $e) {
$erorrMsg = "Invalid Query: " . $connection->error;
break;
};
Now it's working fine, Thank you so much for this tutorial.

Since you are not binding data it’s dangerous for SQL injections. Also, data should be pas into test_input to make sure that injections is also impossible.

شرح اكثر من رائع شكرا لك عزيزي

[@zekrom6537]

OMG EDIT: right after posting this comment i realize whats the error because i read my comment again 🤦‍♂ the error is that its $results not $result its just that missing s what is causing the issues omg BUT then it gives a new error saying Warning: Undefined array key "id" :| ill edit it again if i figure it out i guess
so i found the solution for getting the "warning undefined array key "id" error
inside the edit.php scroll down to where you have the
it should look like this:

[@exenion]

Thk dude for "warning undefined array key "id"

[@user-yi4uq4dx8h]

I clicked on the resubmit form when working on this project the new client form is no longer loading or showing any help

[@benedekszabo9121]

Almost everything is working correctly, but in the edit and in the delete always write that the id variable is not set to the URL. If i write the id manually to the URL (for example 'localhost/myshop/delete.php?id=1) it's working. Does anyone detected this problem?
