PHP access all $_POST[] variables into an array?
提问by Aaron
how to capture all fields in the $_POSTVARIABLE?
into an array?
如何捕获$_POSTVARIABLE中的所有字段？成一个数组？
$email = $_POST;
$emails = array_keys($email);
foreach($emails as $email) {
echo '$' . nl2br($email);
}
$emailadd = new email_save;
$emailadd->insert_email_into_database("POST VARIABLES GO HERE)
I'm trying to make an email list, name and email address,
how do I capture all the variables that where posted that can normal be accessed like
$_POST['email']into an array so i can add them to the arguments in my functions?
我正在尝试制作一个电子邮件列表、姓名和电子邮件地址，我如何捕获所有可以正常访问的变量，例如
$_POST['email']数组，以便我可以将它们添加到我的函数中的参数中？
My form field has 5 fields. The method is POST.
我的表单字段有 5 个字段。方法是POST。
Instead of writing,
而不是写作，
$email = mysql_real_escape_string($_POST['email']);
$firstname = mysql_real_escape_string($_POST['firstname']);
I'm trying to access all the values in the $_POST[] array;
So I can save time getting posted variables
and add functions to those variables like mysql_real_escape_string();
我正在尝试访问 $_POST[] 数组中的所有值；因此，我可以节省获取已发布变量的时间并将函数添加到这些变量中，例如mysql_real_escape_string();
Other security measures will be figured out.
将想出其他安全措施。
I want to be able to add a reffrence of the array to a function so I can add them to the database.
我希望能够将数组的引用添加到函数中，以便将它们添加到数据库中。

If you want to capture a list from a POSTed form, then use the array syntax trick instead of enumerated input field names:
如果要从 POST 表单中捕获列表，请使用数组语法技巧而不是枚举输入字段名称：
<input type="email" name="emails[]">
<input type="email" name="emails[]">
<input type="email" name="emails[]">
This way you need no guessing in PHP, because emails[]becomes an array implicitely then:
这样你就不需要在 PHP 中猜测了，因为这样emails[]就隐式地变成了一个数组：
print_r($_POST["emails"]);
foreach ($_POST["emails"] as $email) {
For database-escaping just use:
对于数据库转义，只需使用：
$db_emails = array_map("mysql_real_escape_string", $_POST["emails"]);
// that's an array too

$_POST is already an array. Why not just pass that?
$_POST 已经是一个数组。为什么不直接通过呢？

Hmm...would something like this help?
嗯……这样的事情会有帮助吗？
<?php
// blank array to hold emails
$emails = array();
foreach ( $_POST as $key => $value )
{
if ( preg_match('/email/', $key) )
{
$this_email = $value;
// quick check to see if it is valid
$this_email = filter_var($this_email, FILTER_VALIDATE_EMAIL);
// also escape it to prevent SQL injections
$this_email = $mysqli->real_escape_string($this_email);
$emails[] = $this_email;
}
}
// $emails is now a nice, clean array of email addresses
$emailadd->insert_email_into_database($emails);
echo '<pre>';
print_r($emails);
echo '</pre>';
?>
<form method="post" action="index.php">
<input type="text" name="email1" /><br />
<input type="text" name="email2" /><br />
<input type="text" name="email3" /><br />
<input type="submit" />
</form>
