# {html_radios}
`{html_radios}` is a [custom function](index.md) that
creates an HTML radio button group. It also takes care of which item is
selected by default as well.
## Attributes
| Attribute Name | Required | Description |
|----------------|-------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| name | No | Name of radio list |
| values | Yes, unless using options attribute | An array of values for radio buttons |
| output | Yes, unless using options attribute | An array of output for radio buttons |
| selected | No | The selected radio element |
| options | Yes, unless using values and output | An associative array of values and output |
| separator | No | String of text to separate each radio item |
| assign | No | Assign radio tags to an array instead of output |
| labels | No | Add <label>-tags to the output (defaults to true) |
| label\_ids | No | Add id-attributes to <label\> and <input\> to the output (defaults to false) |
| escape | No | Escape the output / content (values are always escaped) (defaults to true) |
| strict | No | 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 (defaults to false) |
- Required attributes are `values` and `output`, unless you use
`options` instead.
- All output is XHTML compliant.
- All parameters that are not in the list above are output as
name/value-pairs inside each of the created `<input>`-tags.
## Examples
```php
<?php
$smarty->assign('cust_ids', array(1000,1001,1002,1003));
$smarty->assign('cust_names', array(
'Joe Schmoe',
'Jack Smith',
'Jane Johnson',
'Charlie Brown')
);
$smarty->assign('customer_id', 1001);
```
Where template is:
```smarty
{html_radios name='id' values=$cust_ids output=$cust_names
selected=$customer_id separator='<br />'}
```
```php
<?php
$smarty->assign('cust_radios', array(
1000 => 'Joe Schmoe',
1001 => 'Jack Smith',
1002 => 'Jane Johnson',
1003 => 'Charlie Brown'));
$smarty->assign('customer_id', 1001);
```
Where template is:
```smarty
{html_radios name='id' options=$cust_radios
selected=$customer_id separator='<br />'}
```
Both examples will output:
```html
<label><input type="radio" name="id" value="1000" />Joe Schmoe</label><br />
<label><input type="radio" name="id" value="1001" checked="checked" />Jack Smith</label><br />
<label><input type="radio" name="id" value="1002" />Jane Johnson</label><br />
<label><input type="radio" name="id" value="1003" />Charlie Brown</label><br />
```
```php
<?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($sql));
```
The variable assigned from the database above would be output with the
template:
```smarty
{html_radios name='contact_type_id' options=$contact_types
selected=$contact.contact_type_id separator='<br />'}
```
