Question

我在这里找不到错误。我正在通过以下 html表单

接收数据：

<form action="insertpacient.php" method="POST">
    <br> Prenume:
    <br>
    <textarea name="firstname" required></textarea>
    <br>
    <br> Nume:

    <br>
    <textarea name="lastname" required></textarea>
    <br>
    <br> Sex:

    <br>
    <select name="sex" size="1" required>
        <option value="" selected hidden>Selectați o variantă</option>
        <option value="Feminin">Feminin</option>
        <option value="Masculin">Masculin</option>
    </select>
    <br>
    <br> CNP:

    <br>
    <textarea name="cnp" required></textarea>
    <br>
    <br> Număr de telefon:
    <br>
    <textarea name="phonenumber" required></textarea>
    <br>
    <br> E-mail:

    <br>
    <textarea name="email" required></textarea>
    <br>
    <br> Adresă:

    <br>
    <textarea name="address" style="height:100px;" required></textarea>
    <br>
    <br> Discount:

    <br>
    <select name="producername" size="1" required>
        <option value="" selected hidden>Selectați o variantă</option>
        <option value="5">5%</option>
        <option value="10">10%</option>
        <option value="15">15%</option>
    </select>
    <br>
    <br>

    <input style="width:40%;background-color:#F4FDFE;border-radius: 5px; border:2px outset #FFFFFF; height:24px" type="submit" value="Submit">
</form>

这是 insertpacient.php 文件：

<?php
$firstname   = $_POST['firstname'];
$lastname    = $_POST['lastname'];
$phonenumber = $_POST['phonenumber'];
$cnp         = $_POST['cnp'];
$address     = $_POST['address'];
$email       = $_POST['email'];
$discount    = $_POST['discount'];
$sex         = $_POST['sex'];

if (!empty($firstname) || !empty($lastname) || $sex == 'Selectați o variantă' || $discount == 'Selectați o variantă' || !empty($phonenumber) || !empty($cnp) || !empty($address) || !empty($email)) {
    $host       = "localhost";
    $dbUsername = "root";
    $dbPassword = "";
    $dbname     = "pharmagest";

    $conn = new mysqli($host, $dbUsername, $dbPassword, $dbname);

    if (mysqli_connect_error()) {
        die('Connect Error(' . mysqli_connect_errno() . ')' . mysqli_connect_error());
    } else {
        $SELECT = "SELECT lastname From pacients Where lastname = ? Limit 1";
        $INSERT = "INSERT Into pacients (firstname,lastname,phonenumber,cnp,address,email,discount,sex) values(?,?,?,?,?,?,?,?)";

        $stmt = $conn->prepare($SELECT);
        $stmt->bind_param("s", $lastname);
        $stmt->execute();
        $stmt->bind_result($lastname);
        $stmt->store_result();
        $rnum = $stmt->num_rows;

        if ($rnum == 0) {
            $stmt->close();

            $stmt = $conn->prepare($INSERT);
            $stmt->bind_param("ssddssds", $firstname, $lastname, $phonenumber, $cnp, $address, $email, $discount, $sex);
            $stmt->execute();
            header("Location: insertpacientconfirmationpage.php");
        } else {
            echo "NAH";
        }
        $stmt->close();
        $conn->close();
    }
} else {
    echo 'ERROR';
    die();
}
?>

它确实进入了确认页面，但是由于某种原因数据没有存储在数据库中。

不得不提的是，我使用了完全相同的代码来收集另一个表的数据，但是我不得不更改某些输入类型。

谢谢。

问题1：。您正在发送名称为$_POST['discount']的折扣（producername）。因此，它应该是$_POST['producername']。

问题2：，因为您可以使lastname或其他诸如email或phonenumber之类的列变为唯一，所以您的第一个查询是不必要的。

问题3：：您应该在&&语句中使用||而不是if。或者，您可以重构嵌套的if语句（箭头类型代码）。

<?php

$firstname   = $_POST['firstname'];
$lastname    = $_POST['lastname'];
$phonenumber = $_POST['phonenumber'];
$cnp         = $_POST['cnp'];
$address     = $_POST['address'];
$email       = $_POST['email'];
$discount    = $_POST['producername'];
$sex         = $_POST['sex'];

if (empty($firstname) || empty($lastname) || $sex == 'Selectați o variantă' || $discount == 'Selectați o variantă' || empty($phonenumber) || empty($cnp) || empty($address) || empty($email)) {
    die('Error');
}

$host       = 'localhost';
$dbUsername = 'root';
$dbPassword = '';
$dbname     = 'test';

$conn = new mysqli($host, $dbUsername, $dbPassword, $dbname);

if ($conn->connect_error) {
    die('Connect Error(' . mysqli_connect_errno() . ')' . mysqli_connect_error());
}

$INSERT = 'INSERT INTO pacients (firstname, lastname, phonenumber, cnp, address, email, discount, sex) VALUES (?, ?, ?, ?, ?, ?, ?, ?)';

$stmt = $conn->prepare($INSERT);

if ($stmt->bind_param("ssddssds", $firstname, $lastname, $phonenumber, $cnp, $address, $email, $discount, $sex) && $stmt->execute()) {
    $stmt->close();
    $conn->close();

    header('Location: insertpacientconfirmationpage.php');
}

数据未存储在数据库中
