{html_options}
{html_options} is a
custom function
that creates html <select><option> group
with provided data. It takes care of which item(s) are selected by
default as well. Required attributes are values and output, unless
you use options instead.
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
output is XHTML compatible.
If the optional name attribute is given, the
<select name="groupname"></select> tags will enclose
the option list. Otherwise only the <option> list is generated.
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.
Example 8-10. {html_options}
Example 1:
<?php
$smarty->assign('cust_ids', array(1000,1001,1002,1003));
$smarty->assign('cust_names', array(
'Joe Schmoe',
'Jack Smith',
'Jane Johnson',
'Charlie Brown'));
$smarty->assign('customer_id', 1001);
?>
|
Where template is:
<select name="customer_id">
{html_options values=$cust_ids output=$cust_names selected=$customer_id}
</select> |
Example 2:
<?php
$smarty->assign('cust_options', array(
1000 => 'Joe Schmoe',
1001 => 'Jack Smith',
1002 => 'Jane Johnson',
1003 => 'Charlie Brown')
);
$smarty->assign('customer_id', 1001);
?>
|
where template is:
{html_options name=customer_id options=$cust_options selected=$customer_id} |
Both the above examples will output:
<select name="customer_id">
<option label="Joe Schmoe" value="1000">Joe Schmoe</option>
<option label="Jack Smith" value="1001" selected="selected">Jack Smith</option>
<option label="Jane Johnson" value="1002">Jane Johnson</option>
<option label="Charlie Brown" value="1003">Charlie Brown</option>
</select> |

<?php
$sql = 'select type_id, types from types order by type';
$smarty->assign('types',$db->getAssoc($sql));
$sql = 'select contact_id, name, email, type_id
from contacts where contact_id='.$contact_id;
$smarty->assign('contact',$db->getRow($sql));
?>
|
where the template is:
<select name="type_id">
<option value='null'>-- none --</option>
{html_options name="type" options=$types selected=$contact.type_id}
</select> |
