Front-end: 

<!--商品查询-->
<input type="text" name="bianhao" value="" maxlength="10" size="10" style="width:100px; margin:0px 0px 0px 25px;height:20px;"/>
<input type="submit" value="商品编号查询" style="margin:0px 0px 0px 10px;cursor:pointer;background-color:#C30D23;border:0px;color:#FFFFFF;width:85px;border-radius:5px;padding:3px 0;font-size:13px;"/>

php background receiving and querying: 

public function MallList(){ //写方法
$goods=M(&#39;shop_goods_info&#39;); //实例化数据库对应的表
$codes=I(&#39;param.bianhao&#39;); //获取前台文本框数据
if(isset($codes) && $codes != &#39;&#39;){
$where[&#39;code&#39;]=$codes;
$this->assign(&#39;codes&#39;,$codes); //显示
}
}
$info=$classify->where(array(&#39;code&#39;=>$code))->find(); //查询语法

2. Or:

has $_GET or $_POST

<form action=&#39;&#39; method=&#39;post&#39;>
文本框:<input type=&#39;text&#39; name=&#39;text&#39;>
<input type=&#39;submit&#39; value=&#39;提交&#39;,name=&#39;sub&#39;>
</form>
<?php
if(!empty($_POST[&#39;sub&#39;])){
echo $_POST[&#39;text&#39;]；
}
?>

If it is GET, change it to GET
