我有一个表单，我输入数据并从数据库产品列表中选择一个产品。它工作正常。当我按下提交时，我希望输入数据存储在我的其他mysql表中，但是不保存数据。我没有收到任何错误。
我正在使用类似帖子中的一个例子。
MySQL表：
1 id int(11)
2 Vardas varchar(250) latin1_swedish_ci
3 Pavardė varchar(250) latin1_swedish_ci
4 Asmens kodas int(250)
5 Adresas varchar(250) latin1_swedish_ci
6 Telefono nr. int(250)
7 El.paštas varchar(250) latin1_swedish_ci
8 prekė varchar(250) latin1_swedish_ci
9 Būsena varchar(250) latin1_swedish_ci
我的代码：
<?php
//include the databse connection
include('config/setup.php');
// get the list of products from the database
$q = "SELECT * FROM prekes";
$r = mysqli_query($dbc, $q);
?>
<?php
// check the form has been submitted
if (isset($_POST['submit'])) {
// escape the form fields and assign them to variables
// validate myname to ensure the user entered data
if (isset($_POST['name']) && $_POST['name']!='') {
$name = mysql_real_escape_string($_POST['name']);
} else {
// create an error variable array to store errors to display
$errors[] = 'Please enter your name';
}
// validate agree unless you want to add 'checked' to one of the values
if (isset($_POST['lastName']) && $_POST['lastName']!='') {
$lastname = mysql_real_escape_string($_POST['lastName']);
} else {
$errors[] = 'Please tell us if you agree?';
}
if (isset($_POST['ak']) && $_POST['ak']!='') {
$ak = mysql_real_escape_string($_POST['ak']);
} else {
$errors[] = 'Please tell us if you agree?';
}
if (isset($_POST['adress']) && $_POST['adress']!='') {
$adress = mysql_real_escape_string($_POST['adress']);
} else {
$errors[] = 'Please tell us if you agree?';
}
if (isset($_POST['number']) && $_POST['number']!='') {
$number = mysql_real_escape_string($_POST['number']);
} else {
$errors[] = 'Please tell us if you agree?';
}
if (isset($_POST['email']) && $_POST['email']!='') {
$email = mysql_real_escape_string($_POST['email']);
} else {
$errors[] = 'Please tell us if you agree?';
}
if (isset($_POST['preke']) && $_POST['preke']!='') {
$preke = mysql_real_escape_string($_POST['preke']);
} else {
$errors[] = 'Please tell us if you agree?';
}
//if errors found tell the user else write and execute the query
if ($errors) {
$message = '<p class="error">We found a problem:</p><ul>';
foreach($error as $msg){
$message .= '<li>'.$msg.'</li>';
}
$message .= '</ul><p>Please fix the error/s to continue.</p>';
} else {
// write the query
$query = "INSERT INTO uzsakymai (Vardas, Pavardė, Asmens kodas, Adresas, Telefono nr., El.paštas, prekė)";
$query .= " VALUES ('$name','$lastname','$ak','$adress', '$number', '$email', '$preke')";
// run the query
mysqli_query($dbc, $query);
}
}
?>
