MySQL db isn't populating - php

Question

I am trying to create a register/login html/php script. I created a database and I believe my html/php code is correct. I was wondering if I am missing something small. Here is my code so far.
Here is the database
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
if(isset($_POST["submit"]))
{
$User = "**";
$Password = "**";
$Database = "member";
$Host = "localhost";
$con = mysqli_connect($Host, $User, $Password);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_select_db($con,$Database);
$myusername = $_POST["username"];
$mypassword = $_POST["password"];
$sql = "INSERT INTO member (username, password) VALUES ('$myusername','$mypassword')";
mysqli_query($con,$sql);
mysqli_commit($con);
mysqli_close($con);
echo "Thank You! Information entered.";
}
else
{
?>
<form method="post" action="proInput.php">
Username:<input type="Text" name="username"><br>
Password:<input type="Text" name="password"><br>
<input type="Submit" name="submit" value="Register"></form>
<?
}
?>
Every time I type SELECT * FROM member; in MySQL my database is empty.

Answer 1

mysqli_commit($con);
mysqli_query($con,$sql);
mysqli_close($con);
You're committing before you insert, and then closing an uncommitted transaction. Try swapping the first two lines in the above excerpt.

Answer 2

As you answered already in your comment,
the name of the file isn't main_login.php but proinput.php
Your form is posting it's data to main_login.php and I'm assuming you don't have the insert query on that page, your code isn't run at all.
Options:
Try changing the name of this php file to main_login.php and then instead of the echo redirect the user to the login page
Move this part of the insert to your main_login.php
if(isset($_POST["submit"]))
{
$User = "";
$Password = "";
$Database = "member";
$Host = "localhost";
$con = mysqli_connect($Host, $User, $Password);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_select_db($con,$Database);
$myusername = $_POST["username"];
$mypassword = $_POST["password"];
$sql = "INSERT INTO member (username, password) VALUES ('$myusername','$mypassword')";
mysqli_query($con,$sql);
mysqli_commit($con);
mysqli_close($con);
echo "Thank You! Information entered.";
}
else
{
?>
for debugging add the following to the very top of your php file right after the opening of php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
This worked for me
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
if(isset($_POST["submit"]))
{
$User = "db_user";
$Password = "db_password";
$Database = "db_name";
$Host = "db_host";
$con = mysqli_connect($Host, $User, $Password);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_select_db($con,$Database);
$myusername = $_POST["username"];
$mypassword = $_POST["password"];
$sql = "INSERT INTO member (username, password) VALUES ('$myusername','$mypassword')";
mysqli_query($con,$sql);
mysqli_commit($con);
mysqli_close($con);
echo "Thank You! Information entered.";
}
else
{
?>
<form method="post" action="proinput.php">
Username:<input type="Text" name="username"><br>
Password:<input type="Text" name="password"><br>
<input type="Submit" name="submit" value="Register"></form>
<?php
}
?>

Answer 3

please add 'or die (mysqli_error())' at the end of your query and get the sql error report. That should tell you what is exactly wrong with sql . Php error reporting will only give php errors.
