Updated calls to current Smarty API (register_function()/register_modifier()/register_block() -> registerPlugin(); assign_by_ref() -> assignByRef()). Fixed file includes in templates with quotes. Removed SmartyValidate.class.php includes. Still work in progress as some errors still appear!

{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>
