I need to use PHP file_get_contents() in smarty tpl file. I can't use it in PHP and assign it to smarty template. Because the URL is generated dynamically through loop inside smarty template file. So I'm using smarty plugin function to achieve that task. But I want to know whether is there any way I can use it in template file directly instead of parsing it from plugin file.
I've attached the plugin code which I'm using to achieve this function. Please anyone let me know how to use it in smarty tpl file directly.
function smarty_function_getTitle($params)
{
if ($params['id']) {
$content = file_get_contents("http://youtube.com/get_video_info?video_id=".$params['id']);
parse_str($content, $ytarr);
return $ytarr['title'];
}
}
I've used below code to call it in smarty template:
{getTitle id=$videoId}
Suggestions are welcome!
For those of you reading that didn't read the comments above, myself and OP are both aware that this is not how you use a template engine. He seems to have his reasons for wanting to do this directly in the template rather than a plugin or ahead of time in his code. So don't slag me for demonstrating how, please :)
Here is how you can do it in Smarty.
{"http://youtube.com/get_video_info?video_id=`$videoId`"|file_get_contents|parse_str:$result}
{$result.title}
I did the first part all in one call but if you want to be careful you can split it into multiple calls with checks. But I tested this locally and it worked fine.

I am trying to integrate an ad package into my Smarty based site. I have been given the following PHP code that I need to add to my footer file. But due to it being Smarty I need to add the code instead to my php file so that it can be called/included in my Smarty template file. This was the code that I was given and that I need to include:
<?php if(function_exists('ad_footer')) ad_footer(); ?>
But in the php file I am not sure how to achieve this - I have got this example and wanted to know if it looked correct??
if(function_exists('ad_footer')) {
ob_start();
ad_footer();
$smarty->assign('ad_footer', ob_get_clean());
}
Does the above look the right way to do it?
Thanks in advance
I went ahead and created a test page to see if the above worked and it did so will stick with this code.
I have completely no idea about smarty template system. What I am trying to do is include a php file to get some variable inside a .tpl file (this is a WHMCS template).
I have tried like:
{php} include ('file.php'); {/php} //doesn't work
{include_php file='file.php'} //doesn't work
I have also followed the answer of this question. Still couldn't get it working.
How can I include code.php inside header.tpl of WHMCS? Any help please?
Just for reference: both tpl and php file is in the same directory, if that helps anyway.
It's really not recommended to use php code in Smarty. In fact it's now deprecated and you should avoid such solution as much as possible because it often doesn't have sense.
However if you really want to use PHP in your Smarty files for some reason you need to use SmartyBC (Smarty Backward Compatibility) class instead of Smarty class.
So for example instead of:
require_once(_PS_SMARTY_DIR_.'Smarty.class.php');
$smarty = new Smarty();
you should use:
require_once('SmartyBC.class.php');
$smarty = new SmartyBC();
Then you will be able to use PHP in your Smarty template files
EDIT
If you have just problem with including it's probably your directories problem (however you haven't showed any errors).
I assume you have your files inside your templates directory and you set it properly using:
$smarty->setTemplateDir('templates');
if you simple display index.tpl file in Smarty and you have this PHP file in the same directory (in template directory) you can include it without a path.
However if you include in this index.tpl file another tpl file, when you want to include php file you need to pass the full path to this PHP file, for example:
{include_php 'templates/file.php''}
Your using Smarty the wrong way. The whole point of Smarty is to NOT include any PHP in your presentation bits (views, a.k.a. the good ol' HTML).
So, whatever you're trying to do in that PHP file, just let it do its magic, but send the actual result to Smarty. For example, do you want to show a table of users you get out of a database? Execute the query, fetch the result and pass the results (like an array of results) to smarty like this:
<?php
$smarty = new Smarty();
$users = $db->query('SELECT * FROM users');
// Assign query results to template file.
$smarty->assign('users', $users);
// Compile and display the template.
$smarty->display('header.tpl');
Now, in your smarty template you can access that array like this:
<html>
{foreach from=$users item=user}
Username: {$user->username}<br />
{/foreach}
</html>
I hope you see where I am going. Keep your application logic in the PHP file, and let the template just take care of the looks. Keep the template as dumb as possible!
You get data into Smarty by assigning it. Embedding PHP is not recommended, and deprecated from Smarty 3.
php:
$smarty->assign('foo','bar');
smarty:
{$foo}
i am trying to use smarty with codeigniter, the thing is i worked with codeigniter but never did worked with smarty, but trying learning it.. :)
right now a little issue is that in codeigniter when i need baseurl i use this
<?php echo base_url('styles/bootstrap/css/bootstrap-theme.min.css'); ?>
but how to use it using smarty templates, i mean in smarty .tpl files instead of
i did it like this but it didnt worked for me..
{base_url('styles/bootstrap/css/bootstrap-theme.min.css');}
but got error. i know its not right way but had to try lol..
any ideas?
You made little typo on ";"
{base_url('styles/bootstrap/css/bootstrap-theme.min.css')}
note :
url_helper must be loaded before displaying template
you can use like this I didn't test this
{'styles/bootstrap/css/bootstrap-theme.min.css'|base_url}
or you can write php code inside template
{php}
$this->assign('my_url',base_url('styles/bootstrap/css/bootstrap-theme.min.css'));
{/php}
{$my_url}
see this http://www.smarty.net/docsv2/en/language.function.php.tpl
I have used this function for my controller in form action to redirect to my method it worked .
{base_url('my_controller/my_method')}
I am using PHP in combination with Smarty Templates to generate pages serverside. Currently, I am loading a page as follows:
$smarty->assign('app', file_get_contents("some_content.php"));
Where some content contains HTML with PHP tags and code inside those tags.
I would like the PHP content inside this file within the current scope (That of the script reading the file), so that a particular function I've defined is available. How would I go about doing so? All the information I can find is regarding the eval(...) function, which doesn't seem to be able to cope with the HTML/PHP mixture: would I need to perform a find/eval/replace operation to achieve the desired result, or is there a more elegant way of doing this?
From my opinion, this short snippet of the code you posted shows that something is generally wrong there :)
But nevertheless you can achieve whatever you are trying to achieve by doing the following:
ob_start();
include("some_content.php");
$result = ob_get_clean();
$smarty->assign('app', $result);
Ich, I'm such a dummkopf. There is an answer right on the PHP manual for eval, right under my nose. Here is the answer I neglected to notice.
You can use {literal}...{/literal} smarty tags to display any content in smarty templates as is. It used to transfer java scripts and other specific content.
I have a wordpress theme that I like to duplicate. To make things easier on myself, I'm trying to use the bloginfo function to call my jquery file..like this:
<script type="text/javascript" src="<?php echo bloginfo("template_url"); ?>/js/jquery-1.4.2.min.js"></script>
I just can't get it to work. When I check my source file it looks exactly like the code above.
Can this even be done, or should I just forget it? Thanks guys!
Are you sure the above code is actually in a PHP-file and gets parsed by the server? I can't think of a different reason why PHP-code should just be printed and not executed.
See the Referencing Files From a Template chapter in http://codex.wordpress.org/Theme_Development
Whats the name of this file? It should end in .php.
What does the source look like when you view it from the browser?
Are there other places in the file where you use and is that data correct?
Make sure there are no blank lines at the end of the source file. PHP doesn't like blanks lines at the end of the code.
Two problems: No need for the echo in the WP template tag; should be
<?php bloginfo("template_url"); ?>

And, why are you trying to include jQuery from the template directory, when it resides in wp-includes/js? You should be using Function Reference/wp enqueue script, if your theme doesn't already include jQuery.
You should try to edit your theme's header.php file directly because custom fields of your theme may not be executed by PHP interpreter.
As I've never used PHP, this is only a guess...
PHP is a server side language, and you're tyring to use it on the client side?
