html_options is a custom function that creates html option group with provided data. It takes care of which item(s) are selected by default as well. Required attributes are values and output, unless you use options instead.

If a given value is an array, it will treat it as an html OPTGROUP, and display the groups. Recursion is supported with OPTGROUP. All output is XHTML compatible.

If the optional name attribute is given, the <select name="groupname"></select> tags will enclose the option list. Otherwise only the option list is generated.

All parameters that are not in the list above are printed as name/value-pairs inside the <select>-tag. They are ignored if the optional name is not given.

Example 8-8. html_options

index.php:

require('Smarty.class.php');
$smarty = new Smarty;
$smarty->assign('cust_ids', array(1000,1001,1002,1003));
$smarty->assign('cust_names', array('Joe Schmoe','Jack Smith','Jane
Johnson','Carlie Brown'));
$smarty->assign('customer_id', 1001);
$smarty->display('index.tpl');

index.tpl:

<select name=customer_id>
	{html_options values=$cust_ids selected=$customer_id output=$cust_names}
</select>


index.php:

require('Smarty.class.php');
$smarty = new Smarty;
$smarty->assign('cust_options', array(
			1001 => 'Joe Schmoe',
			1002 => 'Jack Smith',
			1003 => 'Jane Johnson',
			1004 => 'Charlie Brown'));
$smarty->assign('customer_id', 1001);
$smarty->display('index.tpl');

index.tpl:

<select name=customer_id>
	{html_options options=$cust_options selected=$customer_id}
</select>


OUTPUT: (both examples)

<select name=customer_id>
	<option value="1000">Joe Schmoe</option>
	<option value="1001" selected="selected">Jack Smith</option>
	<option value="1002">Jane Johnson</option>
	<option value="1003">Charlie Brown</option>
</select>
