How to use php code in a tpl file

[bogdean]

Hi. i have this code 

<?php

function getcurlway($url) {
    $content=file_get_contents($url);
    return $content;
}

function pick($start,$stop,$from){
@$from=explode($start,$from);
@$from=explode($stop,$from[1]);
@$from=$from[0];
return $from;
}

$ch = curl_init(); 

$url="http://blog.larisfashion.ro/";
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_REFERER, "http://blog.larisfashion.ro/");
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); 

$file = curl_exec($ch); 
curl_close($ch); 
$cons=explode('<article id',$file);
$cc=count($cons);
for($i=1; $i<=3; $i++){
$link=pick('<h2>','</h2>',$cons[$i]);
$text=pick('</a></p>','</article>',$cons[$i]);
$img=pick('<img src="','"',$cons[$i]);

echo $link.'<br>';
echo $text.'<br>';
echo $img.'<br>';

}
?>

how can i use this in a tpl file? any ideas? thanks

It's the opposite of what tpl is meant for. The correct way would be to write a module and hand over the results of your php into a smarty array. This array could then be referenced within the tpl - same way as every module does it.

 

If you insist to go the wrong way - this is the syntax to run php within tpl.

{php}echo "this is php code running within a smarty file!"{/php}

It is possible that you have to change the smarty class to allow this. Change smarty class php

$php_handling = SMARTY_PHP_ALLOW;

i've changed  Smarty_class.php  and put   

 public $php_handling = self::PHP_ALLOW;

 

instead of PHP_PASSTHRU but my page doesn't work completly when i use <?php or {php}

You cannot include php in Smarty pages. The {php} label works only on older versions of Smarty, not the one implemented in Prestashop.

It's the wrong way anyway. Somehow one could run php inside tpl, but it's crap then.

Normal way would be to include the code at the place where thie correspoinding tpl is fired.

[musicmaster]

The usual way to handle this is to have the code run in the place where the page is generated and to assign the result to a Smarty variable that is then used in the tpl file. 

 

For example the product page is created when the file /controllers/front/ProductController.php calls/implements the product.tpl file in its function initContent. So you should run in that file (or an override of it) the extra code and assign it to a Smarty variable that you then use in the product.tpl file.

That is exactely the way it should be. Since we do not know where the asking bogdean want's to implement this php, we can just guess.

 

Other thoughts:

• Your not checking character encoding
• Your do not perform any kind of input validation
• Your code just relies on data should be where you expect it to be
• If formatting of the source page changes, you're code will most likely fail.
• The user agent isn't set this way you used it.

 

Overall:

I have to say it here:

It's a very sloppy programmed pice of source coude.

This code would never ever run on a machine I have responsibility for.

 

Better but also not secure would be to use the rss feed of the source page.
