获取表单数组并发送到电子邮件

Question

所以我还在学习 PHP，我有一个包含 4 个数组的表单。我正在尝试将阵列与其他一些信息一起发送到我的电子邮件中。我不断收到的电子邮件说“数组，数组”（然后其余信息正确显示）。我无法弄清楚我错过了什么。

我可以让家长信息正确显示，但我一直坚持让孩子信息翻译成电子邮件。

if (isset($_POST['submit'])){
    // Parent Info
    $pFname = mysql_escape_string($_POST['pFname']);
    $pLname = mysql_escape_string($_POST['pLname']);
    $email = mysql_escape_string($_POST['pEmail']);
    $street = mysql_escape_string($_POST['street']);
    $city = mysql_escape_string($_POST['city']);
    $state = mysql_escape_string($_POST['state']);
    $zip = mysql_escape_string($_POST['zip']);

    // Child Info
    $name = mysql_escape_string($_POST['Name']);
    $birthday = mysql_escape_string($_POST['Birthday']);
    $gender = mysql_escape_string($_POST['Gender']);
    $rel = mysql_escape_string($_POST['Rel']);

    $msg1 = "From: " . ' ' . $pFname . ' ' . $pLname  . ' ' . ' ' . $pEmail 
    . ' ' . ' ';

    foreach ($_POST['Name'] as $names){
        $name = $names;
    }

    foreach ($_POST['Birthday'] as $birthdays){
        $birthday = $birthdays;
    }

    foreach ($_POST['Gender'] as $genders){
        $gender = $genders;
    }

    foreach ($_POST['Rel'] as $rels) {
        $rel = $rels;
    }

    $msg = "Name: " . " " . $name . " - " . $gender .  "Birthday: " . 
     $birthday . " " . "Relationship: " . $rel . "\n\r";

    $to = 'joe@joe.com;
    $subject = 'Birthday Club Application';
    $msg = $msg . "\r\n";
    $msg .= "First Name: " . $pFname . "\r\n";
    $msg .= "Last Name: " . $pLname . "\r\n";
    $msg .= "Email: " . $email . "\r\n";
    $msg .= "Street: " . $street . "\r\n";
    $msg .= "City: " . $city . "\r\n";
    $msg .= "State: " . $state . "\r\n";
    $msg .= "Zip: " . $zip . "\r\n";

    $headers = 'From: ' . $pEmail . "\r\n";
    $headers1 = 'From: mycompany.com';
    /*$goto_after_mail = "birthdayClub.php";*/

    mail($to, $subject, $msg, $msg1, $headers);

    header("Location: " . $goto_after_mail);
}

这是 HTML：

<form id="parent-info" method="post" action="<?php echo 
 htmlspecialchars($_SERVER[" PHP_SELF "])?>">

    <h1>Guardian Information</h1>
    <h4>*All fields required*</h4>

    <input type="text" name="pFname" class="parent-entry" placeholder="First Name:" >

    <input type="text" name="pLname" class="parent-entry" placeholder="Last Name:" >

    <input type="text" name="pEmail" class="parent-entry" placeholder="Email:" >

    <input type="text" name="street" class="parent-entry" placeholder="Street Address:" >

    <input type="text" name="city" class="parent-entry" placeholder="City:" >

    <input type="text" name="state" class="parent-entry" placeholder="State:" >

    <input type="text" name="zip" class="parent-entry" placeholder="Zip Code:" >
    <br>

    <h2>Child Information</h2>
    <h4>*All fields required*</h4>

    <div class="child-form">

        <input type="text" name="Name[]" placeholder="Childs Name:" class="parent-entry" value " "; >

        <input type="text" name="Gender[]" placeholder="Gender:" class="parent-entry" value " ";>

        <input type="text" name="Birthday[]" placeholder="Ex: 1/1/01:" class="parent-entry" value " "; >

        <input type="text" name="Rel[]" placeholder="Relation to child:" class="parent-entry" value " ";>

    </div>

Answer 1

 foreach ($_POST['Name'] as $names)

这一行表明$_POST['Name'] 是一个数组。如果是这种情况，您将遇到此行的问题：

$name = mysql_escape_string($_POST['Name']);

该函数需要一个字符串。当你给它一个数组时，它会将它转换为字符串“Array”。这同样适用于所有子数组。你在数组上使用mysql_escape_string。

由于您似乎有一组孩子，您想要做的是循环遍历该数组并获取每个孩子的信息以添加到电子邮件中。

如果您不想遍历所有这些数组，另一种选择是使用print_r 函数，并将其第二个可选参数设置为true。这会将数组转换为用户可读的字符串。

改变

$name = mysql_escape_string($_POST['Name']);

收件人：

$name = print_r($_POST['Name'], true);
