 Posted: Wed Dec 12, 2007 4:42 pm Post subject: Sweet function replacement for html_options |
 |
|
I was just about to create my own html_options function that allows you to pass in an array of objects for which you could choose the key and value
for example
| Code: |
class test
{
var id;
var name;
function test($id, $name)
{
$this->id = $id;
$this->name = $name;
}
}
$test[] = new test(1, "ABC");
$test[] = new test(2, "DEF");
$test[] = new test(3, "ASDF");
$smarty->assign("test", $test);
|
SO if I created an array of test objects.
I could then pass this array to HTML objects selected id as key, and name as value, and then output the options.
I thought I would just do a quick google first, and sure enough, someone else already created this a while ago.
I checked the forums, and it doesn't seem like anyone else posted it, so
here is the code!
I am not sure who original author is, so cannot give credit. But I do not take any credit for this code
Install instructions.
Open function.html_options.php
and replace the smarty_function_html_options
with this one. (Leave other 2 functions in there)
Save
Looking over it (and doing testing myself) this is backwards compatible with the array html_options so you should have no issues with the existing ones in your code.
Call this function like so
{html_options name='test' options=$test key_prop='id' val_prop='name'}
| Code: |
function smarty_function_html_options($params, &$smarty)
{
require_once $smarty->_get_plugin_filepath('shared','escape_special_chars');
$name = null;
$values = null;
$options = null;
$selected = array();
$output = null;
$extra = '';
//added for dealing with array of objects for options
$pKey = null;
$pValue = null;
foreach($params as $_key => $_val)
{
switch($_key)
{
case 'name':
$$_key = (string)$_val;
break;
case 'options':
if ( is_object($_val) ) //leave as an object
$$_key = (object)$_val;
else
$$_key = (array)$_val;
break;
case 'selected':
case 'values':
case 'output':
$$_key = array_values((array)$_val);
break;
case 'key_prop':
$pKey = (string)$_val;
break;
case 'val_prop':
$pValue = (string)$_val;
break;
case 'multiple':
$extra .= ' '.$_key . '';
default:
$extra .= ' '.$_key.'="'.smarty_function_escape_special_chars($_val).'"';
break;
}
}
if (!isset($options) && !isset($values))
return ''; /* raise error here? */
$_html_result = '';
if (is_array($options)) {
while ( list($_key, $_val) = each($options) ){
if ( is_object($_val) ) {
if ( !$pValue ) return; //required for an array of objects.
$_objvars = get_object_vars((object)$_val);
if ( $pKey ) {
$_key = $_objvars[$pKey];
}
$_val = $_objvars[$pValue];
}
if ( is_array($_val) ) {
if ( !$pValue ) return; //required for an array of arrays.
if ( $pKey ) {
$_key = $_val[$pKey];
}
$_val = $_val[$pValue];
}
$_html_result .= smarty_function_html_options_optoutput($_key, $_val, $selected);
}
} elseif(is_object($options)) {
$_objvars = get_object_vars($_val);
while ( list($_val, $_key) = each($_objvars) ) {
$_html_result .= smarty_function_html_options_optoutput($_key, $_val, $selected);
}
} else {
foreach ((array)$values as $_i=>$_key) {
$_val = isset($output[$_i]) ? $output[$_i] : '';
$_html_result .= smarty_function_html_options_optoutput($_key, $_val, $selected);
}
}
if(!empty($name)) {
$_html_result = '<select name="' . $name . '"' . $extra . '>' . "\n" . $_html_result . '</select>' . "\n";
}
return $_html_result;
}

I will definitely be using this myself quite a bit |
