{$Variable_name}

Variables are the dynamic contents of the templates, you can assign them with assign() method. Variables are case_sensitive.

My age is {$age}  // 30

You can do simple operations such as + - * / % with numbers, string and other variables and also use = for assign a value to a variable

{$year=30}
My age is {$age+$year}  // 60

You can use functions with variables

My name is {$name|substr:0,3}  // Rai

Use {$GLOBALS} to access all globals variable as _SESSION, _GET, _POST, _SERVER.

{#constant#}

You can constants with this syntax: {#constant#}

{if="condition"}{/if}

Is the equivalent of php if. You can use variable and php into the condition.

{if condition="$age < 20"}
    less than 20 years
{elseif condition="$age < 30"}
     less than 30 years
{else}
     30 or more
{/if}

 

{loop="array"}{/loop}

This tag allow you to loop an array, it's useful to print a list of articles, news.

{loop="user"}
 {$value.user_id} - {$value.name} - {$value.phone}
{/loop}

Betweein {loop} and {/loop} you can use special variables:

• {$key}, key of the array element.
• {$value}, value of the array.
• 0, loop counter, it starts from 0. If you want starts from 1: {$counter+1}. If you do {$counter%2+1} each cycle will return 1 and 2.

 

{include="template"}

{include="layout/header"}

{function="myFunc"}

{function="pagination($selected_page)"}

 

{* comment *}

All between {* and *} is deleted in the compiled file. Use this tag to comment your templates.

{* 'sup dude? I'm a comment *}

 

{noparse}{/noparse}

All the code between {noparse} {/noparse} it won't be parsed

Hey {noparse}how are you {$name}{/noparse}?

Output:

Hey how are you {$name}?

WYSIWYG - Path replace

This cool feature allows designers to create templates as regular HTML with images and styles with relative paths, RainTPL replaces automatically these paths with the correct server paths.

Absolute paths and paths ending with # will be not changed.

<link href="style.css" type="text/css" rel="stylesheet">
<img src="img/logo.gif">

Output html:

<link href="tpl/style.css" type="text/css" rel="stylesheet">
<img src="tpl/img/logo.gif">

Note: if you set raintpl::$base_url, RainTPL will replace the path with raintpl::$base_url.

Assign and draw

This is what you've to write in your script to assign variables and draw the template.

$tpl = new raintpl(); //include Rain TPL
$tpl->assign( "age", "30" ); // assign variable
$tpl->assign( array( "age" => "30", "name" => "Rain" ) ); // associative array
$tpl->assign( "user", $user ); // assign an array
$tpl->draw( "mytemplate" ); // draw the template
