Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

# {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 />'}
|
|
```
|
