1. 表单元素的获取

PHP中获取表单元素的方法较为简单、纯净、易于理解,跟ASP.NET差别很大,我们新建一个页面Index.php用于递交表单:

<form id="formMain" action="Action.php" method="post">	<input name="txtName" type="text" /><br />	<input name="txtAge" type="text" /><br />	<input name="btnSumbit" type="submit" value="Submit" /></form>
Copy after login

注意页面中的text元素用name标识,若写成id则无法获取,在Action.php中获取表单中的值,并打印出来:

Your name: <?php echo $_POST["txtName"]; ?><br />Your age: <?php echo $_POST["txtAge"] ?>
Copy after login

这里使用了$_POST[“”],填入表单元素的name即可获取该元素的值。

$_POST中存放了post方式提交的数据,若为get方式则用$_GET,若不关心来源也可使用$_REQUEST,它其中包含了get、post、cookie和file的数据。
