在填表单的时候,有时候会出现表单未填完就提交的情况,这时候若是想要回到原来的表单页面,一般之前填的内容都会消失掉。
故使用PHP实现回到原来表单但是填写数据不消失,代码?如下
1<?php if (isset($_POST)) { $name = $_POST['username'] ?? NULL; $text = $_POST['text'] ?? NULL; if (isset($_POST['like'])) { foreach ($_POST['like'] as $key => $value) $check[$value] = "checked"; } } ?> <!DOCTYPE html> <html> <head> <title>FORM</title> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="http://cdn.amazeui.org/amazeui/2.7.2/css/amazeui.min.css"> </head> <body> <div class="am-container"> <form class="am-form" method="post" action="index.php"> <legend>黏性表单</legend> <div class="am-form-group"> <label for="doc-ipt-name">用户名</label> <input type="text" placeholder="给个名字吧" name="username" value=<?php if echo $name ??
