Question

我有一个问题，我插入记录，它也插入电子邮件部分工作，但当确认页面显示它只显示数组中的最后一条记录3次。我想把它放在for循环中显示所有记录。我不确定我做错了什么会继续搞清楚这个问题。

process_insert.php

<html>
    <head>
    <title></title>
    </head>
    <body>
    <?php
        ini_set('display_errors', 1);
    error_reporting(~0);

    $serverName = "localhost";
    $userName = "root";
    $userPassword = "";
    $dbName = "blog_samples";

    $conn = mysqli_connect($serverName,$userName,$userPassword,$dbName);

    $rows_count = count($_POST["name"]);

    $message = '';

    for($i=0;$i<$rows_count;$i++){

        // PREVENTING SQL INJECTION !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

        $employee_name = mysqli_real_escape_string($conn,$_POST["employee_name"][$i]);
        $name = mysqli_real_escape_string($conn,$_POST["name"][$i]);
        $code = mysqli_real_escape_string($conn,$_POST["code"][$i]);
        $quantity = intval($_POST["quantity"][$i]);
        $price = mysqli_real_escape_string($conn,$_POST["price"][$i]);


        $sql = "INSERT INTO order_table ( employee_name, name, code, quantity, price) 
            VALUES ('$employee_name', '$name', '$code', '$quantity', '$price')";

        $query = mysqli_query($conn,$sql);


        if(mysqli_affected_rows($conn)>0) {


                $message .=

                "employee_name: " . $employee_name . "

    }

    if ( ! empty($message)) {
        $to = "xgrh@gmail.com";
        $subject = "Supplies";
        $headers = "From: user@gmail.com"; 

        mail($to,$subject,$message,$headers);

Answer 1

这是因为变量$ name，$ code，$ amount和$ price具有$ _POST的最后一个值。您可以使用上一个循环的$ _POST值或使用此值创建变量。

请改为尝试：

<html>
<head>
<title></title>
</head>
<body>
<?php
    ini_set('display_errors', 1);
error_reporting(~0);

$serverName = "localhost";
$userName = "root";
$userPassword = "";
$dbName = "blog_samples";

$conn = mysqli_connect($serverName,$userName,$userPassword,$dbName);

$rows_count = count($_POST["name"]);

$message = '';
$data = array();

for($i=0;$i<$rows_count;$i++){

    // PREVENTING SQL INJECTION !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    $employee_name = mysqli_real_escape_string($conn,$_POST["employee_name"][$i]);
    $name = mysqli_real_escape_string($conn,$_POST["name"][$i]);
    $code = mysqli_real_escape_string($conn,$_POST["code"][$i]);
    $quantity = intval($_POST["quantity"][$i]);
    $price = mysqli_real_escape_string($conn,$_POST["price"][$i]);

    array_push($data, array(
        'employee_name' => $employee_name,
        'name' => $name,
        'code' => $code,
        'quantity' => $quantity,
        'price' => $price,

    ));
    $sql = "INSERT INTO order_table ( employee_name, name, code, quantity, price) 
        VALUES ('$employee_name', '$name', '$code', '$quantity', '$price')";

    $query = mysqli_query($conn,$sql);


    if(mysqli_affected_rows($conn)>0) {


            $message .=

            "employee_name: " . $employee_name . " 

            " ."name: ".  $name ." 

            ". "code: " . $code . " 

            " ."quantity: ".  $quantity . " 

            ". "price: " . $price . "";
    }

}

if ( ! empty($message)) {
    $to = "xgrh@gmail.com";
    $subject = "Supplies";
    $headers = "From: user@gmail.com"; 

    mail($to,$subject,$message,$headers); 
}


?>

    </tr>



    <?php foreach ($data as $value) {?>


    <tr>
        <td class="style">name: <?php echo $value['name']; ?></td>
    </tr>
    <tr>
        <td class="style">  code: <?php echo $value['code'];  ?></td>
