help : looping for template

based on this tutor
http://codewalkers.com/tutorials/58/1.html (Writing a Template System in PHP by Timothy Boronczyk)
and iam trying to implement it like this :

php Code:

Original - php Code

 
<?php
require_once("lib/template.php");
 
$page = new Page("template.html");
 
$page->replace_tags(array(
  "tittle_c_sender" => "Sender",
  "title_c_message" => "Message",
  ));
 
$query=('SELECT * FROM guestbook ORDER BY ID DESC LIMIT=10');
$result=mysql_query($query);
while ($row=mysql_fetch_array($result)){
  $page->replace_tags(array(
  "sender_name" => $row['sender_name'],
  "sender_mail" => $row['sender_email'],
  "message" => $row['message'],
  ));
}
$page->output();
?>

but when i try to acces the page i am only see one record (from table guestbook) and the other is gone
pls any body help me to show all my guestbook content to my template

thanks,

RE: help : looping for template

The problem is with the loop. The first iteration of the loop relaces the place-holder tags. The second time around the tags have already been replaced, so there will be nothing left to match.

RE: help : looping for template

after iam try to doing the looping my code is like this :

php Code:

Original - php Code

 
<?php
require_once("lib/template.php");
 
$page = new Page("template.html");
 
$page->replace_tags(array(
  "tittle_c_sender" => "Sender",
  "title_c_message" => "Message",
  ));
 
$query=('SELECT * FROM guestbook ORDER BY ID DESC LIMIT=10');
$result=mysql_query($query);
$name_sender=array();
$email_sender=array();
$message=array();
$total=array();
while ($row=mysql_fetch_array($result)){
$name_sender[]=$row['sender_name'];
$email_sender[]=$row['sender_mail'];
$message[]=$row['message']
$total[]=$row['g_id'];
  }
$total_id=count($total);
for($i = 0; $i < $total_id; $i++){
page->replace_tags(array(
"sender_name"   =>  $name_sender,
"sender_mail"   =>  $email_sender,
"message"       =>  $message,
));
}
$page->output();
?>

but iam still confused how to handle the replacement tag with variabel that content array

RE: help : looping for template

The class doesn't support looping like this. The place holder tags are replaced after the first run of the loop. There is nothing to replace the 2nd, 3rd, etc. time the loop runs.

RE: help : looping for template

I have added two methods so this class can handle with blocks/iterations from mysql-queries. But I'm not sure this is the fastest way for replacing the data.
a block would look like this:

php Code:

Original - php Code
<!-- START block --> I need some repeated data here: {data} <!-- END block -->

<!-- START block -->
I need some repeated data here: {data}
<!-- END block -->

All the code:

php Code:

Original - php Code

class Page{
  var $page;
 
  function Page($template = "templates/error.tpl") {
    if (file_exists($template)){
      $this->page = join("", file($template));
      $this->page = str_replace(".", ".", $this->page);
    }else{
      die("De templatefile $template was niet gevonden.");
    }
  }
 
  function parse($file) {
    ob_start();
    include($file);
    $buffer = ob_get_contents();
    $buffer = str_replace(".", ".", $buffer);
    ob_end_clean();
    return $buffer;
  }
 
  function replace_tags($tags = array()) {
    if (sizeof($tags) > 0){
      foreach ($tags as $tag => $data) {
        $data = (file_exists($data)) ? $this->parse($data) : $data;
    $data = ($tag == "bericht") ? $this->smily($data) : $data;
        $this->page = str_replace("{" . $tag . "}", $data, $this->page);
        }
    } else {
      die("Geen tags om te vervangen");
    }
  }
 
  function block($block){
    preg_match ('#<!-- START '. $block . ' -->([^.]+)<!-- END '. $block . ' -->#',$this->page,$this->return);
    $code = str_replace ('<!-- START '. $block . ' -->', "", $this->return[0]);
    $code = str_replace ('<!-- END ' . $block . ' -->', "", $code);
    return $code;
  }
 
  function replace_block_tags($blockname,$query,$count){
    $count = ($count == "") ? $count = mysql_num_rows($query) : $count;
    $this->blockcode = $this->block($blockname);
    if ($count > 0){
        for ($i = 1; $i <= $count; $i++){
            $tags = mysql_fetch_array($query);
            foreach ($tags as $tag => $data) {
                $data = (file_exists($data)) ? $this->parse($data) : $data;
                $this->code = str_replace("{" . $tag . "}", $data, $this->blockcode);
          }
            $this->block_page .= $this->blockcode ."n";
      }
    } else {
        $this->block_page = "No data to replace";
    }
    $this->page = str_replace($this->return[0], $this->block_page, $this->page);
  }
 
  function output() {
    $this->page = str_replace(".", ".", $this->page);
    echo $this->page;
  }
}

Can anyone examine the code & give me some advise if there are faster solutions?
Thanx, BlackSkad

RE: help : looping for template

ive tried using this block code above but i cant figure it?

im doing this;

$tp->block('choices');
$tags = array('choices' => $choices);
$tp->replace_block_tags('choices',"SELECT * FROM `poll_choices` WHERE `poll_id` = '" . $poll_info['id'] . "'",$count);

Am i doing it wrong?
