邮箱的POST复选框值?

时间:2012-12-12 16:43:31

标签: php email checkbox

我有一个简单的复选框示例,它记住表单提交后选择的内容并且出现错误。

那部分效果很好......但是,我想将结果“已检查”的框发布到我的表单邮件功能中。

我现在只报告如果选中或取消选中,我希望选中复选框的“值”而不选中未选中的复选框。

<?php

$CB_1 = 'unchecked';
$CB_2 = 'unchecked';
$CB_3 = 'unchecked';
$CB_4 = 'unchecked';
$CB_5 = 'unchecked';

if (isset($_POST['submit'])) {

if (isset($_POST['CB_1'])) {$CB_1 = $_POST['CB_1'];
if ($CB_1 == 'item_01') {$CB_1 = 'checked';}
}

if (isset($_POST['CB_2'])) {$CB_2 = $_POST['CB_2'];
if ($CB_2 == 'item_02') {$CB_2 = 'checked';}
}

if (isset($_POST['CB_3'])) {$CB_3 = $_POST['CB_3'];
if ($CB_3 == 'item_03') {$CB_3 = 'checked';}
}

if (isset($_POST['CB_4'])) {$CB_4 = $_POST['CB_4'];
if ($CB_4 == 'item_04') {$CB_4 = 'checked';}
}

if (isset($_POST['CB_5'])) {$CB_5 = $_POST['CB_5'];
if ($CB_5 == 'item_05') {$CB_5 = 'checked';}
}
}

if (isset($_POST['submit'])) {
$error  = "";

    if (!empty($_POST['email'])) {
    $email = $_POST['email'];

    if (!preg_match("/^[a-z0-9]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $email)){ 
    $error .= "E-mail address not valid.";
    }

    } else {

    $error .= "E-mail address is required.";
    }

    if (empty($error)) {

    $from = 'From: '. @TEST .' <'. $email .'>';
    $to = "someone@company.com";
    $subject = "CHECKBOX TEST";
    $content = "

我知道这可能不一定能回答这个问题,但是一种可以使代码更有效的方法就是这样做。

for($i=1; $i<=5;$i++)
{

     if(isset($_POST['submit'])&& isset($_POST['CB_'.$i]) && $CB_.$i=='item_0'.$i)
     {
        $CB_.$i = $_POST['CB_'.$i];
        $CB_.$i = 'checked';
     }
}

如果以这种方式修复它,它也可能使我们更容易调试。

好吧,我找到了一种方法来做我想做的事,但我很确定这不是那种有PHP实际经验的人会这样做的。有什么建议吗?

redelman431,谢谢你的建议,但这对我的技术水平来说太高级了。

我找到了我想要的东西,我想在一个阵列的方式,我认为'redelman431'试图让我去做,但当时对我没有任何意义。

然后我偶然发现了'DavidBélanger'的另一个阵列,由于某些原因我对我更有意义所以我把它用在我的复选框中,它的工作非常棒。

新问题是,我无法获得已经检查过的复选框,以便记住,如果页面上的其他地方出现了错误,这是一个灾难,因为我的最终表单有很多。

有什么想法吗?
