1. The following is the CI framework

1. Put all the fields to be received in the array

　Example:

　　I want to receive: id, name, age, mobile and other fields

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

Copy after login

2. for loop Just judge

<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>);

Copy after login

2. Source code judgment method (no more nonsense, go directly to the code)

<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>);

Copy after login

Conclusion:

In fact, both CI framework and source code can use the source code method (2) , but in order to verify the security, we only use the first solution. The other methods called above are built-in with PHP. If you don’t understand which method, you can check the PHP help document (the master ignores it)

The above introduces the CI framework. The source code is a one-time method to determine whether a certain field value of the postget data is empty, including post and source code. I hope it will be helpful to friends who are interested in PHP tutorials.
