Insert user input from textbox to Database (PHP to PHPMYADMIN using mysql)
Question
How do you guys insert user input from textbox(html/php) to database (phpmyadmin) using mysql
I keep getting the error "failed to insert" is there something missing with my code.
I did search online on how to fix it but nothing is working. I think something is missing with my code and I can't pin point it.
all files below are in 1 php file named index.php
<!DOCTYPE html>
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'dad_trading';
$dbconn = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($db);
if (isset($_POST['submit']))
{
$Lastname = $_POST['LastName'];
$firstname = $_POST['FirstName'];
$Middlename = $_POST['MiddleName'];
$address = $_POST['Address'];
$city = $_POST['City'];
$zipcode = $_POST['ZipCode'];
$email = $_POST['email'];
$number = $_POST['number'];
$query = ("INSERT INTO customer ([LName], [FName], [MName], [Street], [City], [ZipCode], [Email], [ContactNo]) VALUES ('$Lastname', '$firstname', '$Middlename', '$address', '$city','$zipcode', '$email', '$number')");
if(mysql_query($query))
{
echo "<script>alert('INSERTED SUCCESSFULLY');</script>";
}
else
{
echo "<script>alert('FAILED TO INSERT');</script>";
}
}
?>

尝试使用服务器变量添加表单操作
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">

Here's an example of code that works. From w3Schools . mysql_connect is deprecated, new mysqli works.
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
Having tried myself to make your code work and as a beginner not knowing it was broken, I came across a few issues using your code. I leave this out for anyone who could end up here while learning on how to insert data in a database and to anyone who could want to point out the mistakes OP made by editing this answer.

I fixed the OP for my purposes, and it worked for me. Goal was to create database entries from a web form for some testing.
<html>
<head>
<meta charset="UTF-8">
<title>sample</title>
</head>
<?php
//These $variables related to the form data html elements eg "<input
//name="City"" input name=values, case sensitive which are derived from
//the //form submit with POST type, from the form at the end of this code
//block.
if (isset($_POST['submit']))
{
$Lastname = $_POST['LastName'];
$firstname = $_POST['FirstName'];
$Middlename = $_POST['MiddleName'];
$address = $_POST['Address'];
$city = $_POST['City'];
$zipcode = $_POST['ZipCode'];
$email = $_POST['email'];
$number = $_POST['number'];
//This is the sql query to apply the form inpur field values into the
database //from the user form in the web page. There is no validation
checking, which //an example at TutorialRepublic for CRUD and php...:
https://www.tutorialrepublic.com/php-tutorial/php-mysql-crud-
application.php
//...Is really much more thorough.
$con = mysqli_connect('localhost','root','Levaral','test');
$query = "INSERT INTO customer (LastName, FirstName, MiddleName,
Address, City, Zipcode, email, number) VALUES (" . " '" . $Lastname .
"', '" . $firstname . "', '" . $Middlename . "', '" . $address . "', '" .
$city . "', '" . $zipcode . "', '" . $email . "', '" . $number . "')";
if (mysqli_query($con,$query))
{
echo "<script>alert('INSERTED SUCCESSFULLY');</script>";
}
else
{
echo "<script>alert('FAILED TO INSERT');</script>";
}
}
?>

//put html element data in a <form> so you can send the data here by POST
//type, this stumped me
//at first when I was starting.
//I guess since the form is in the same page, it is available to the PHP
//function as some default.
<form action="" method = "POST">
First name:
Middle Name:
Last Name:<br>
<input name="FirstName" size="15" style="height: 19px;" type="text" required>

//This part below was just for my feedback to see if it worked by
