一.创建模板:
将页面中经常出现的部分复制到一个html或php文件中,在原页面中用require()/include()函数引入。
例子:
源html:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <body> <form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"/></p><p><span>立即学习</span>“<a href="https://pan.quark.cn/s/7fc7563c4182" style="text-decoration: underline !important; color: blue; font-weight: bolder;" rel="nofollow" target="_blank">PHP免费学习笔记(深入)</a>”;</p> <input type="submit" value="send"></form><div><p>This is the foot of the document</p></div></body> </html>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <body>
<div><p>This is the foot of the document</p></div></body> </html>
<?phprequire('header.html');?><form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"/></p><p><span>立即学习</span>“<a href="https://pan.quark.cn/s/7fc7563c4182" style="text-decoration: underline !important; color: blue; font-weight: bolder;" rel="nofollow" target="_blank">PHP免费学习笔记(深入)</a>”;</p> <input type="submit" value="send"></form><?phprequire('footer.html');?>
二、处理表单??让一个页面同时显示和处理表单
使用条件语句:
if (表单提交) { 处理表单 }
else { 显示表单 }
例子:简单的 用户名-密码验证
输入:用户名:YF 密码:123456
显示:登陆成功
裁图:
代码:ws.php(其中header.html、footer.html引用的是上文中的模板):
<?phpdefine('TITLE', 'Login');require('header.html');if (isset($_POST['submitted'])) { if ((!empty($_POST['name'])) && (!empty($_POST['password']))){ if ((strtolower($_POST['name']) == 'yf') && ($_POST['password'] == '123456')){// name and password are correct. print '<p> logged in !</p>'; } else { print '<p> name or password is worry!</p>'; } } else { print '<p> make sure you enter both name and password!</p>'; }}else { print '<form action="ws.php" method="post"> <p> Name:<input type="text" name="name" size="20"/></p> <p>Password:<input type="password" name="password" "size="20" /></p> <input type="submit" value="send"> <input type="hidden" name="submitted" value="true"/> </form>'; }require('footer.html');?>
