{html\_options} {#language.function.html.options}
===============
`{html_options}` is a [custom function](#language.custom.functions) 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'));
$smarty->assign('customer_id', 92);
?>
The above arrays would be output with the following template (note the
use of the php [`count()`](&url.php-manual;function.count) function as a
modifier to set the select size).
<select name="customer_id" size="{$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($sql));
?>
Where a template could be as follows. Note the use of the
[`truncate`](#language.modifier.truncate) modifier.
<select name="type_id">
<option value='null'>-- none --</option>
{html_options options=$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>
