 Posted: Tue Mar 24, 2015 12:39 pm Post subject: Template Inheritance - Variable Scope |
 |
|
I'm not sure if this has come up before, but I search the forums and search engines with no results.
I'm creating a template for my billing software, and wanted to use Smarty 3 functionality by adding the template inheritance support.
There's 3 pages. Layout.tpl, Index.tpl, Index.php
I'm assigning a boolean in Index.php in this way:
| Code: | $client = new Client();
$template->assign('isLoggedIn', $client->isLoggedIn());
$template->display("{$theme}/index.tpl"); |
The above code returns true/false.
Index.tpl extends Layout.tpl.
In Layout.tpl, I used:
| Code: | | {if $isLoggedIn}Test{/if} |
And it didn't work, but if I move that code to Index.tpl, it works.
So, the "Template Inheritance" only supports local scope, and not global.
Could this be fixed?
Thanks. |

| STC? I mean, simple test case? From your verbose description it isn't clear, what you are doing. |

Example:
Layout.tpl
| Code: | <!DOCTYPE html>
<html>
<head>
<title>{$pageName}</title>
</head>
<body>
{block name=pageContent}{/block}
</body>
</html> |
Index.tpl
| Code: | {extends file="layout.tpl"}
{block name=pageContent}
{$pageName}
{/block} |
Index.php
| Code: | <?php
require_once 'libs/Smarty.class.php';
$template = new Smarty();
$template->setTemplateDir('templates/views'); // path to templates folder
$template->setCompileDir('templates/tmp'); // path the compile folder
$template->setCacheDir('templates/cache'); // path to cache folder
$template->assign('pageName', 'Hello World');
$template->display("index.tpl"); |
After that, if you visit index.php, you'll get the page name echoed out, but the page title would be empty. |

I can't reproduce your problem.
In your first code example you load index.tpl from a theme subfolder. {extends 'layout.tpl'} will load layout.tpl from the template root folder. So ar you sure that you load the right layout.tpl ?
Which Smarty version do you use? |

I'm using the latest version of Smarty.
The path to the layout file is correct, since all the HTML source shows up on View Source on the browser.
The problem here is that if you assign a value to a variable, and then display the index.tpl, that variable won't get assigned to the "extended file = layout.tpl".
So the variable is local to only the displayed file, but the extended file doesn't receive the variable value. |

I also fixed the problem, but it's not that clean.
The solution is adding the line below after {extends}:
{assign var="isLoggedIn" value="$isLoggedIn"} |

All what you said does not make any sense. In Smarty 3.1 inheritance is a compile time process where the {block}{/block} sections are merged together that the output of the compiler is one template which has just one context.
Can you please provide the content of the compiled template file xxxx.file.index.tpl.php from the template_c folder. |
