有许多链接可以让你知道如何处理php中复选框的帖子值.请看这个链接:http://www.html-form-guide.com/php-form/php-form-checkbox.html

单一复选框

HTML代码:

<form action="checkbox-form.php" method="post">
    Do you need wheelchair access?
    <input type="checkbox" name="formWheelchair" value="Yes" />
    <input type="submit" name="formSubmit" value="Submit" />
</form>

PHP代码:

<?php

if (isset($_POST['formWheelchair']) && $_POST['formWheelchair'] == 'Yes') 
{
    echo "Need wheelchair access.";
}
else
{
    echo "Do not Need wheelchair access.";
}    

?>

复选框组

<form action="checkbox-form.php" method="post">
    Which buildings do you want access to?<br />
    <input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />
    <input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />
    <input type="checkbox" name="formDoor[]" value="C" />Carnegie Complex<br />
    <input type="checkbox" name="formDoor[]" value="D" />Drake Commons<br />
    <input type="checkbox" name="formDoor[]" value="E" />Elliot House

    <input type="submit" name="formSubmit" value="Submit" />
 /form>

<?php
  $aDoor = $_POST['formDoor'];
  if(empty($aDoor)) 
  {
    echo("You didn't select any buildings.");
  } 
  else
  {
    $N = count($aDoor);

    echo("You selected $N door(s): ");
    for($i=0; $i < $N; $i++)
    {
      echo($aDoor[$i] . " ");
    }
  }
?>

Answer 2

在正常情况下，复选框返回一个开/关值。

您可以使用以下代码进行验证：

<form action method="POST">
      <input type="checkbox" name="hello"/>
</form>

<?php
if(isset($_POST['hello'])) echo('<p>'.$_POST['hello'].'</p>');
?>

这将返回

<p>off</p>

或者

<p>on</p>

Answer 3

你应该使用

<input type="submit" value="submit" />

在你的里面form.

并添加action到您的form标签中，例如：

<form action="booking.php" method="post">

它将您的表单发布到您选择的操作中。

从 php 你可以通过以下方式获取这个值

$_POST['booking-check'];
