PHP开发简单图书借阅系统之用户登录页
继续使用<form>表单和<table>表格来创建登录页面
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <form name="myform" method="post" onSubmit="return CheckPost()" action="" style="margin-bottom:5px;"> <table width="" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td height="" colspan="2" bgcolor="#FFFFFF">用户登录</td> </tr> <tr> <td width="" align="right" bgcolor="#FFFFFF">用户名: </td> <td width="" bgcolor="#FFFFFF"><input type="text" name="username"></td> </tr> <tr> <td align="right" bgcolor="#FFFFFF">密 码: </td> <td bgcolor="#FFFFFF"><input type="password" name="password"></td> </tr> <tr> <td align="right" bgcolor="#FFFFFF"><a href="reg.php">注册新用户</a> </td> <td bgcolor="#FFFFFF"><input type="submit" name="submit" value="登录"></td> </tr> </table> </form>
增加了一个“注册新用户”跳转页，如果没有注册则跳转到注册页面注册。
