{html_options}

{html_options} is a custom function that creates the html <select><option> group with the assigned data. It takes care of which item(s) are selected by default as well.

Attribute Name Type Required Default Description

   values             array         Yes, unless using options attribute    *n/a*   An array of values for dropdown
   output             array         Yes, unless using options attribute    *n/a*   An array of output for dropdown
  selected        string/array                      No                    *empty*  The selected option element(s)
  options       associative array   Yes, unless using values and output    *n/a*   An associative array of values and output
    name             string                         No                    *empty*  Name of select group
   strict            boolean                        No                    *FALSE*  Will make the \"extra\" attributes *disabled* and *readonly* only be set, if they were supplied with either boolean *TRUE* or string *\"disabled\"* and *\"readonly\"* respectively

Required attributes are values and output, unless you use the combined options instead.
If the optional name attribute is given, the <select></select> tags are created, otherwise ONLY the <option> list is generated.
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 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.
All output is XHTML compliant.

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

The following template will generate a drop-down list. Note the presence of the name attribute which creates the <select> tags.

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

Output of the above example would be:

<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);
?>

The above arrays would be output with the following template (note the use of the php count() function as a modifier to set the select size).

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

The above example would output:

<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));

?>

Where a template could be as follows. Note the use of the truncate modifier.

<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);
?>

The script above and the following template

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

would output:

<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>
