{html_radios}

{html_radios} is a custom function that creates a HTML radio button group. It also takes care of which item is selected by default as well.

Attribute Name Type Required Default Description
name string No radio Name of radio list
values array Yes, unless using options attribute n/a An array of values for radio buttons
output array Yes, unless using options attribute n/a An array of output for radio buttons
selected string No empty The selected radio element
options associative array Yes, unless using values and output n/a An associative array of values and output
separator string No empty String of text to separate each radio item
assign string No empty Assign radio tags to an array instead of output
labels boolean No TRUE Add <label>-tags to the output
label_ids boolean No FALSE Add id-attributes to <label> and <input> to the output
escape boolean No TRUE Escape the output / content (values are always escaped)
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 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.

Example 8.13. {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 8.14. {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><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 />

  

Example 8.15. {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 />'}
