[@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.

[@Mr.samomar]

@@seint1044 Your welcome

[@zekrom6537]

wow thank you was worth reading all comments to finally find a solution, my guess is that the youtuber added some extra lines somewhere that we cant see in the video thats why it doesnt work for us but does for him, but its not erorrMsg its errorMessage you made a typo there i assume but it works

[@ramsuthar3473]

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.

[@ferdinardajaba2691]

Hello. How do you bind data plz?

When I click edit it says: "Invalid query: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1". Did anyone know why?

[@mayonnaise.8210]

This is my problem right now, I don't know what is the problem is😢

[@BaukeC]

What if you remove the '' around the $id in the query (...... WHERE id=$id")

[@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?

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:

This is very concise but as such it was prone to errors; I spent about a month to troubleshoot this and get it to "work". I was missing end tags and syntax errors as I tried to replicate the process.

in the (edit.php),

if I remove the ' ' from the $id, it throws an error in this line ( $result = $conection->query($sql); )
