 Posted: Sat Apr 24, 2010 2:04 am Post subject: Printing value of a Magical variable |
 |
|
It is not really good to write lengthy codes  This magical modifier reduces possible PHP codes into a brief template code. It searches for values of an index in $_POST, $_GET, $_SESSION and $_COOKIE according to your priorities.
For example, the normal PHP code would be:
| Code: |
$subdomain_id = $_POST['subdomain_id'];
#... search more in $_GET, $_SESSION, $_COOKIE...
$smarty->assign('subdomain_id', $subdomain_id);
|
This can lead to too much of repetitions in your several .php files. But the below mentioned magical modifier removes this burden completely, and puts everything within the template code's FORM elements. A sample usage is:
| Code: | | <select name="subdomain_id">{html_options options=$options selected='subdomain_id'|magical}</select> |
Traditionally, you would first need to assigin the variable, and use it:
| Code: | | <select name="subdomain_id">{html_options options=$options selected=$subdomain_id}</select> |

Basic Code: modifier.magical.php
| Code: |
<?php
/**
* Magical value reader
* Searching for an existing indexed value on $_POST, $_GET, $_SESSION, $_COOKIE.
* Makes sure that the return value is always a string.
*/
function smarty_modifier_magical($variable_index='')
{
$value = '';
switch(true)
{
case isset($_POST[$variable_index]):
# Most frequent chance
$value = "{$_POST[$variable_index]}";
break;
case isset($_GET[$variable_index]):
$value = "{$_GET[$variable_index]}";
break;
case isset($_SESSION[$variable_index]):
# Average change
$value = "{$_SESSION[$variable_index]}";
break;
case isset($_COOKIE[$variable_index]):
$value = "{$_COOKIE[$variable_index]}";
break;
default:
}
return($value);
}
?> |
I appreciate your comments and queries about this modifier.
