CI框架，源代码一次性判断获取post(get)数据是否有某个字段值为空方法，cipost

一、以下是CI框架

1、把所有的要接收的字段放在数组中

　　例：

　　　　我要接收：id,name,age,mobile 等字段

<span>$req</span> = <span>array</span>('id','name','age','mobile');

2、for循环判断即可

<span>1</span> <span>for</span>(<span>$i</span> = 0;<span>$i</span> < <span>count</span>(<span>$req</span>);<span>$i</span> ++<span> ){    
</span><span>2</span>     <span>$j</span> = <span>$this</span>->load->get_post(<span>$req</span>[<span>$i</span>],<span>true</span><span>);
</span><span>3</span>     <span>if</span>(<span>empty</span>(<span>$j</span><span>))
</span><span>4</span>             <span>exit</span>(<span>$req</span>[<span>$i</span>].' 为空'<span>);
</span><span>5</span>     <span>$data</span>[<span>$i</span>] = <span>$j</span><span>;
</span><span>6</span> <span>}
</span><span>7</span>     <span>print_r</span>(<span>$data</span>);

二、源代码判断方法（就不废话了，直接上代码）

<span>$req</span> = <span>array</span>('id','name','age','mobile'<span>);
</span><span>for</span>(<span>$i</span> = 0;<span>$i</span> < <span>count</span>(<span>$req</span>);<span>$i</span> ++<span> ){    
     </span><span>$j</span> = <span>$_POST</span>[<span>$req</span>[<span>$i</span><span>]];
     </span><span>if</span>(<span>empty</span>(<span>$j</span><span>))
             </span><span>exit</span>(<span>$req</span>[<span>$i</span>].' 为空'<span>);
     </span><span>$data</span>[<span>$i</span>] = <span>$j</span><span>;
}
     </span><span>print_r</span>(<span>$data</span>);

 

结束语：

　　其实CI框架与源代码都可以用源代码这种方法（二），但是为了验证安全性，使用第一种方案而已，以上调用的其他方法是php自带的，哪个方法不懂，可以查一下PHP 帮助文档（大神忽略）
