Calling PHP from Smarty template - php

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.

Execute the Code in a PHP Page And Echo the HTML Output

I absolutely don't post a question here in SO unless I really can't find a way to solve my problem myself. I did a lot of googling and was not able to find a solution for this one problem I am about to describe.
Here is the problem. I am creating a templated php website. With templated I mean something like below:
<?php include("header.php");?>
<div id="content">
<div id="main">
<h2><?php echo($page_title);?></h2>
<?php
echo ($page_content);
?>
</div>
<?php include("sidebar.php");?>
</div>
<?php include("footer.php");?>
As you can see here page template ECHOES the content of the $page_content variable between header and footer sections to build the page.
To keep the code clean and separated (in my own way) I have been placing the html content in .txt files (let's say page1_content.txt) and assigning the txt content to this variable ($page_content) as below:
$page_content = file_get_contents("page1_content.txt");
My problem starts when I place some php code in page1_content.txt, lets' call this file page2_content.php (yes, I change the file from .txt to .php). Then I assign the content of this file to $page_content variable as below as usual:
$page_content = file_get_contents("page2_content.php");
Now, when the page template ECHOES page2_content.php contents the php code in it is also echoed as string and not executed, but I am trying to query a database and do some stuff in this file with some php code. I mean, I want the php code inside page2_content.php to be executed and the cumulative html code to be echoed by the "echo" line inside the template file.
How can I achieve this?
Please ask me any questions if you need more info/clarification.
Thanks
EDİT:
As many people here suggested the solution was including the file. Actually, I tried including the file before but it didn't look like it was working, it broke my template, so I though I was on the wrong track and quit the "include" way of doing this. Since everybody here is advising to use include I tried that again. I replaced the php code in "page2_content.php" with a basic 1-line code just to see if it gets executed before adding generated html code without breaking the template and it worked. Apparently my php code had a problem at first place and hence broke my template execution.
Now I have changed the template structure slightly and pages using the template, and it seems to work nicely. Thanks a lot everybody. I have up-voted every answer suggesting that I use include :)
As #Ali suggested, you could include the files. The other option which I highly suggest you do not use is the eval() function.
I think what you want to do is to include your content PHP file, not echo it (as you are doing with header.php and footer.php).
echo($page_content);
Would become as below:
include("page2_content.php");
You've already done this in your footer and sidebar, just use include()

replacement for php file_get_contents in smarty template?

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.

custom php function to call in header

I have a Wordpress website. I am asking for help as I am not good with codes, but know a bit about the flow of functions and all.
I want to add a new PHP function that will be defined in a separate file. The function to be defined is required to serve a 728x90 banner ad on top of the header area of the site (so I guess the php function will also have CSS styling to align the ad in the center). I don't know what I am saying will be possible the way I am saying.
Alternatively, there might be a way to call a js function defined in separate file, then called in the php header to serve the banner (again center-aligned).
I am seeking help here as Stackoverflow also helped me solve problems previously.
Is there anyone who can help me get this thing done?
Once you have your PHP handler written in a separate file call it using require_once like this:
<?php
require_once('myfile.php');
// Wordpress Stuff
?>
I guess PHP have no relation with CSS/styling, you can do it with Javascript.
like this or using JQuery

PHP + Smarty: Parse PHP+HTML into a String?

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.

Can PHP be inserted into a javascript call in my header?

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"); ?>
Template Tags/info « WordPress Codex
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?
