数据表单
<p>表单以<form>开头,以</form>结尾,action为数据提交的目标地址
form表单用的最多的是input标签,name为提交数据的名称,value为input标签的默认值,type为类型,一般默认为text,表示输入框,当type为submit时是提交按钮
name为自定义变量</p>
<pre><code class="language-html"> <form action="http://thinkcmf.zpe/zpeadmin/yonghuliebiao/yonghuliebiao_list">
姓名:<input name="user_name" value="{$name}" type="text">
年龄:<input name="nianling" type="text">
<input type="submit" value="确定">
</form></code></pre>

<p>点击表单提交按钮后,数据提交到action对应的php函数路劲</p>
<pre><code class="language-php">public function yonghuliebiao_list()
{
$name = input("user_name","");//接受从表单提交的数据
dump($name);
}</code></pre>
