Example 8-16. {html_radios} first example


<?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:

{html_radios name='id' values=$cust_ids output=$cust_names
       selected=$customer_id separator='<br />'}

Example 8-17. {html_radios} second example


<?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:

{html_radios name='id' options=$cust_radios
     selected=$customer_id separator='<br />'}

Both examples will output:

<label for="id_1000">
<input type="radio" name="id" value="1000" id="id_1000" />Joe Schmoe</label><br />
<label for="id_1001"><input type="radio" name="id" value="1001" id="id_1001" checked="checked" />Jack Smith</label><br />
<label for="id_1002"><input type="radio" name="id" value="1002" id="id_1002" />Jane Johnson</label><br />
<label for="id_1003"><input type="radio" name="id" value="1003" id="id_1003" />Charlie Brown</label><br />

Example 8-18. {html_radios} - Database example (eg PEAR or ADODB):


<?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:

{html_radios name='contact_type_id' options=$contact_types
     selected=$contact.contact_type_id separator='<br />'}
