Smarty

[Aristotle]

I REALLY need a way to have html_options take an array for the selected parameter.

index.php:

[php:1:a91b4338a0]<?php

require('Smarty.class.php');
$smarty = new Smarty;
$smarty->assign('cust_options', array(
1001 => 'Joe Schmoe',
1002 => 'Jack Smith',
1003 => 'Jane Johnson',
1004 => 'Charlie Brown'));
$smarty->assign('customer_ids', array(1001,1003));
$smarty->display('index.tpl');

?>[/php:1:a91b4338a0]

index.tpl:

Figured it out:

(plugin found in OurCMS Smarty package)

[php:1:dfe3a1df2c]<?php /* $Id$ */

/*
*
* Smarty plugin
* -------------------------------------------------------------
* Type: function
* Name: html_options
* Purpose: Prints the list of <option> tags generated from
* the passed parameters
* -------------------------------------------------------------
*/
function smarty_function_html_options($params, &$smarty)
{
$print_result = true;

extract($params);


$html_result = '';

settype($selected, 'array');
if (isset($options)) {
settype($options, 'array');

// sort will work only with $options to keep key=>value association.
if (!empty($sort))
{
switch ($sort)
{
// sort by key
case "keys":
ksort($options);
break;
// sort by key reverse order
case "rkeys":
krsort($options);
break;
// sort by values keeping index association
case "vals":
asort($options);
break;
// sort by values keeping index association, by reverse order
case "rvals":
arsort($options);
break;
}
}


foreach ($options as $key => $value) {
$html_result .= "<option value=\"$key\"";
if (in_array($key, $selected))
$html_result .= " selected=\"selected\"";
$html_result .= ">$value</option>\n";
}
} else {
settype($output, 'array');
settype($values, 'array');
for ($i = 0, $for_max = count($output); $i < $for_max; $i++) {
/* By default, check value against $selected */
$sel_check = $values[$i];
$html_result .= "<option";
if ($i < count($values))
$html_result .= " value=\"".$values[$i]."\"";
else
$sel_check = $output[$i]; /* if more outputs than values, then
check output against $selected */
if (in_array($sel_check, $selected))
$html_result .= " selected=\"selected\"";
$html_result .= ">".$output[$i]."</option>\n";
}
}

if ($print_result)
print $html_result;
else
return $html_result;
}

/* vim: set expandtab: */

?>[/php:1:dfe3a1df2c]

This really should become a standard Smarty feature.

did you bother to check http://smarty.php.net/manual/en/language.function.html.options.php ?
the "selected"-attribute can be a string or an array.

Actually, I did see that. It just wasn't working for some reason, perhaps because the html_options was inside a {section} loop. That seems to goof things up at times. More than likely, though, it was human error, and something I did (typo?) was the reason for the problem. I must have fixed it sometime between trying the OurCMS plugin and fiddling around with other things, though...I'll try the same template with the standard Smarty plugin and see if it works.

And it does...must have been a template syntax error or something. Sorry.
