Smarty:html_options函數(shù)

<?php
$smarty->assign('myOptions', array(
                                1800 => 'Joe Schmoe',
                                9904 => 'Jack Smith',
                                2003 => 'Charlie Brown')
                                );
$smarty->assign('mySelect', 9904);
?>

下面模板將生成一個下拉列表。 注意name提供了值，所以會生成 <select>標(biāo)簽。

{html_options name=foo options=$myOptions selected=$mySelect}

輸出：

<select name="foo">
<option value="1800">Joe Schmoe</option>
<option value="9904" selected="selected">Jack Smith</option>
<option value="2003">Charlie Brown</option>
</select>

<?php
$smarty->assign('cust_ids', array(56,92,13));
$smarty->assign('cust_names', array(
                              'Joe Schmoe',
                              'Jane Johnson',
                              'Charlie Brown'));
$smarty->assign('customer_id', 92);
?>

上面的兩個數(shù)組，將會如下輸出HTML (注意這里有使用了PHP的 count()函數(shù)作為修飾器來計算size值).

<select name="customer_id" size="{$cust_names|@count}">
   {html_options values=$cust_ids output=$cust_names selected=$customer_id}
</select>

輸出：

<select name="customer_id" size="3">
    <option value="56">Joe Schmoe</option>
    <option value="92" selected="selected">Jane Johnson</option>
    <option value="13">Charlie Brown</option>
</select>

<?php

$sql = 'select type_id, types from contact_types order by type';
$smarty->assign('contact_types',$db->getAssoc($sql));

$sql = 'select contact_id, name, email, contact_type_id
        from contacts where contact_id='.$contact_id;
$smarty->assign('contact',$db->getRow($sql));

?>

下面是模板，注意使用了 truncate 修飾器。

<select name="type_id">
    <option value='null'>-- none --</option>
    {html_options options=$contact_types|truncate:20 selected=$contact.type_id}
</select>

<?php
$arr['Sport'] = array(6 => 'Golf', 9 => 'Cricket',7 => 'Swim');
$arr['Rest']  = array(3 => 'Sauna',1 => 'Massage');
$smarty->assign('lookups', $arr);
$smarty->assign('fav', 7);
?>

而模板里：

{html_options name=foo options=$lookups selected=$fav}

輸出：

<select name="foo">
<optgroup label="Sport">
<option value="6">Golf</option>
<option value="9">Cricket</option>
<option value="7" selected="selected">Swim</option>
</optgroup>
<optgroup label="Rest">
<option value="3">Sauna</option>
<option value="1">Massage</option>
</optgroup>
</select>
