Add Edit Delete form not adding into MySQL no errors
Question
I have this Add Edit Delete form, the problem is: when I put everything and I click on ADD it says "Data added successfully." but the data isn't in my table of phpAdmin and it not shows in the page... Or is simply because my hoster doens't work with MySQLi but with MySQL? Without talking about SQL Injections because Im not so expert and dont know how protect from that, this pages will be protected with login area so only restricted members will access to it.

//$result = mysql_query("SELECT * FROM users ORDER BY id DESC"); // mysql_query is deprecated
$result = mysqli_query($mysqli, "SELECT * FROM `user` ORDER BY id DESC"); // using mysqli_query instead

It not doesn't says or shows any errors or any other problems, it says only data added successfully and nothing else. I don't understand why it doesn't add any data in my tables, i checked everything again and again, maybe because i'm tired but i tried to rename tables names but nothing change, is the same...

Spotted three errors,
add.php : Column names should be without ''. Check the following
$result = mysqli_query($mysqli, "INSERT INTO user (steamUE,steamPW,steam_GC) VALUES ('$steamUE','$steamPW','$steamGC')");
edit.php : '' missing from $id . Check the following
$result = mysqli_query($mysqli, "UPDATE user SET steamUE='$steamUE',steamPW='$steamPW',steamGC='$steamGC' WHERE id='$id'");
delete.php : '' missing from $id . Check the following
$result = mysqli_query($mysqli, "DELETE * FROM user WHERE id='$id'");
If the connection with DB is successful, it must work (and this answer deserves a green tick from you :D).
Or is simply because my hoster doens't work with MySQLi but with MySQL?
Wherever I faced issues, I got some error or a blank page.

Check your dB connection. Turn to mysqli, declair it with $sql with (errno), but call your param before $sql. Use if condition to check your connection. On your add please use prepared with $stmnt and execute it.
