[Resolved] Template Class Help

[NateDawg]

OK the code below is a simple template class I'm using for a new posting script. I want to modify it so that I can call up one template(main.tpl) and then replace the text <#CONTENT#> with another template file (news.tpl) that is called within a while statement.

Both main.tpl and news.tpl have many different template tags like <#name#> that need to be replaced as well.

Any help in making this happen would be very much appreciated!

class template {

   private $template;


function load($filepath) {
      $this->template = file_get_contents($filepath);
      $this->template = ereg_replace("<!-- START COMMENTS -->(.*\s*)<!-- END COMMENTS -->", "",
      $this->template);
   }

 function replace($var, $content) {
      $this->template = str_ireplace("<#$var#>", $content, $this->template);
   }

   function publish() {
      echo $this->template;
      }

}

so you know, that class requires php5

it could be modified to work w/ php4 though if needed.

i would add another method to the class. currently the only way to get the contents is to output it, which you may not always want to do.

you could get around it by using output buffering and capturing the output from publish(), but its easier to just make the class more functional.

function get_contents() {
    return $this->template;
}

<?php

require_once 'class.template.php';

// first lets handle the news template

$news_template = new template();

$news_template->load('news.tpl');


// replace something
$var = 'NEWS_HEADER';
$replacement = 'something';
$news_template->replace($var, $replacement);

// replace another something
$var = 'FOO';
$replacement = 'something else';
$news_template->replace($var, $replacement);

// now lets make out main object
$main_template = new template();

$main_template->load('main.tpl');

$var = 'CONTENT';
// get the finished news template
$replacement = $news_template->get_contents();

$main_template->replace($var, $replacement);

$main_template->publish();


?>

Yes I do know that 🙂

I still need help replacing the text in one file with the other looping file 🙁

[rehfeld]

i edited it. is that what your talking about?

[NateDawg]

I never thought about loading the news template first. Anyway that seems to be what I need but I'm getting an error 🙁

Fatal error: Call to a member function get_contents() on a non-object in C:\Program Files\Apache Group\Apache2\htdocs\news\index.php on line 94

line 94 is ...
$replacement = $news_template->get_contents();

Can I get some help with this too please?

[rehfeld]

does the variable $news_template exist?

you need to have
$news_template = new template();
before trying to use it.

[NateDawg]

Your right I needed to make $news_template = new template();

But this dosn't give me the results I wanted. The suggested code above outputs the news.tpl file with the replacements and then the main.tpl file after it with the replacements. I need the replacements to be made to both files and then have the text in main.tpl be raplaced with news.tpl(with the replacements)

thats exactly what the example i provided does.

take a closer look at what i posted.

it sounds like your doing this

$replacement = $news_template->publish(); 

instead of what i showed you to do

$replacement = $news_template->get_contents(); 

this is the exact reason i said to add the get_contents() method

if you still cant figure it out, post your code.

[NateDawg]

OK this is the template class

I renamed get_contents() to contents()

I worked with the code a bit and now the templates are replacing each other ok but instead of showing all of the results from my news query it only shows the last result.

class template {

   private $template;
   function load($filepath) {
      $this->template = file_get_contents($filepath);
      $this->template = ereg_replace("<!-- START COMMENTS -->(.*\s*)<!-- END COMMENTS -->", "",
      $this->template);
   }


   function contents() {
    return $this->template;
	}

   function replace($var, $content) {
      $this->template = str_ireplace("<#$var#>", $content, $this->template);
   }

   function publish() {
      echo $this->template;
      }
}

Here is the code in the while loop

$template = new template;

$template->load("template/news_tpl.html");

$template->replace("member_name", "$member_name");

$template->replace("website", "$member_website");

And this is the final code that calls the main template and echos the output.

$main_template = new template();
$main_template->load("template/main_tpl.html");
$replacement = $template->contents();
$main_template->replace("CONTENT", $replacement);

$main_template->publish();

I still need some help getting the news template to loop 🙁

[NateDawg]

Anyone?

[rehfeld]

$main_template = new template();
$main_template->load("template/main_tpl.html"); 


loop () {

$template = new template;
$template->load("template/news_tpl.html");

$template->replace("member_name", "$member_name");

$template->replace("website", "$member_website");

// now we add the result to our main template so it doesnt get lost on the next loop iteration
$main_template->replace($some_var, $template->contents());


}

[NateDawg]

OK I finally found a solution! Thanks for all you help rehfeld.

//At the top....

$main_template = new template();
$main_template->load("template/main_tpl.html");


//The code in the loop

while{

$template = new template;
	$template->load("template/news_tpl.html");
	$template->replace("member_name", "$member_name");
	$template->replace("website", "$member_website");

//THIS PART IS THE KEY
$replacement .= $template->contents();

}

//And at the end publish it 

$main_template->replace("CONTENT", "$replacement");
$main_template->publish();
