Question

I want to be able to change the PHP variables $dispname and $banstat in the code below with a HTML form.
<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
$servername = "localhost";
$username = "foo";
$password = "bar";
$dbname = "wordpress";
$banstat = '1';
$dispname = "Brendan";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "UPDATE wp_oxygenpurchaseusers SET user_url=$banstat WHERE display_name=$dispname";
if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;

Answer 1

There were some multiple issues in your code.
Try
<?php
if (isset($_GET['p']) && $_GET['p'] == "login")
{
/* Database Connection Info */
$servername = "localhost";
$username = "foo";
$password = "bar";
$dbname = "wordpress";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
/* getting form values */
$banstat = mysqli_real_escape_string($conn, $_GET['banstat']);//'1';
$dispname = mysqli_real_escape_string($conn, $_GET['dispname']);
$sql = "UPDATE wp_oxygenpurchaseusers SET user_url='$banstat' WHERE display_name='$dispname'";
if ($conn->query($sql) === TRUE)
{
echo "Record updated successfully";
}
else
{
echo "Error updating record: " . $conn->error;
}
$conn->close();
}
?>

Errors in your code
You open two forms.
You are using post method in form but using get method in php code.
Your variables were not updating.

Answer 2

You need get $_POST and set variable
$dispname = $_POST['name'];
Errors in your code:
You open two forms and just close one
If you want use post instead get check $_POST
<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
if ($_POST) {
//update variables and update bd
}
}
?>

Answer 3

Okay, so I took both of the other answers provided from #javi and #Hassan and used them to re-write it, I took the majority of the code from Hassan's and then changed a few things using Javi's and put this together. I figured maybe someone else could use this. Thanks again guys.
<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
if ($_POST) {
$servername = "localhost";
$username = "foo";
$password = "bar";
$dbname = "wordpress";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$banstat = $_POST['banstat'];
$dispname = $_POST['dispname'];
$sql = "UPDATE wp_oxygenpurchaseusers SET user_url=$banstat WHERE user_login='$dispname'";
if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}
$conn->close();
}
