An example of Smarty's simple method of generating form elements, smarty form

This article describes an example of Smarty's simple method of generating form elements. Share it with everyone for your reference, the details are as follows:

The principle of smarty generating form elements is to give smarty an array to generate and display menus or options, and in addition, pass the value of an option for matching the default selection:

An example is as follows:

php file: index.php

<&#63;php 
include("smarty_inc.php");
$smarty->assign('cust_ids',array(1000,1001,1002,1003));
$smarty->assign('cust_names',array('丁庆','闫磊','吕东','宋子健'));
$smarty->assign('customer_id',1003);
$smarty->display("index.html");
&#63;>

Template file: index.html

<select name=customer_id onkeypress="">
<{html_options values=$cust_ids selected=$customer_id output=$cust_names}>
</select>
<hr />
<{html_radios name="id" values=$cust_ids selected=$customer_id output=$cust_names }>
