i create a template file for my site… it’s like: <!– template.php –> <?php

  • 0

i create a template file for my site… it’s like:

<!-- template.php -->
<?php function showheader() { ?>
<head><body>
<!-- some of style files and menus -->
<div class="content">
<?php } ?>

<?php function showfooter() { ?>
</div></body></html>
<?php } ?>

i use this file as a template like this:

<?php include_once("template.php"); showheader(); ?>
content text or photo or ... etc.
<?php showfooter(); ?>

that’s all… but if i try to use a connection on template file, it screw up!
i used an external file like:

<?php
//
// include_once connection file
// query strings goes here
//

do {
echo $row_table['id']; //example
} while ($row_table = mysql_fetch_assoc($table));

?>

and i use this file as include_once(“filename.php”); on template file… at this point it gives errors… like what is this connection variable, what is this connection string… etc. it cannot reach connection strings…

by the way, i use another external connection like:

<?php
global $hostname_conn,$database_conn,$username_conn,$password_conn,$conn;
$hostname_conn = "localhost";
$database_conn = "test";
$username_conn = "****";
$password_conn = "****";
$conn = mysql_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error(mysql_error(),E_USER_ERROR); 
mysql_query("SET NAMES 'utf8'");
?>

i’m gonna cry! what’s the problem… and do you know another way to use template…
thanks much…

PS: i change variables on conn.php as global (and it didnt work) and i change include, include_once, require, require_once where i include files but it didnt give anything.

    This separates the page into two PHP files: (1) the first obtains the data, and (2) the second displays the data.

    While getting data, not a single character should be printed out.
    If some errors occurred, display an error page.

    Once you get all your data with no errors – it’s time to include a template. The template has two PHP files as well: the template for the page itself and the template that is shared in common by all the pages in the site.

    By sorting things this way you’ll solve all your present and future templating problems.

    A typical script may look like

    <?
//include our settings, connect to database etc.
include dirname($_SERVER['DOCUMENT_ROOT']).'/cfg/settings.php';
//getting required data
$DATA=dbgetarr("SELECT * FROM links");
$pagetitle = "Links to friend sites";
//etc
//and then call a template:
$tpl = "links.php";
include "template.php";
?>

    where template.php is your main site template, including common parts, like header, footer, menu etc:

    <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My site. <?=$pagetitle?></title>
</head>
<body>
<div id="page">
<? include $tpl ?>
</div>
</body>
</html>

    and links.php is the actual page template:

    <h2><?=$pagetitle?></h2>
<ul>
<? foreach($DATA as $row): ?>
<li><a href="<?=$row['link']?>" target="_blank"><?=$row['name']?></a></li>
<? endforeach ?>
<ul>

    easy, clean and maintainable.

    settings.php contains all common settings:

    <?php
$hostname_conn,$database_conn,$username_conn,$password_conn,$conn;
$hostname_conn = "localhost";
$database_conn = "test";
$username_conn = "****";
$password_conn = "****";
$conn = mysql_connect($hostname_conn, $username_conn, $password_conn) 
         or trigger_error(mysql_error(),E_USER_ERROR); 
mysql_query("SET NAMES 'utf8'") or trigger_error(mysql_error(),E_USER_ERROR);

$tpl = "default.php";
$pagetitle = "";

function dbgetarr(){
  $a     = array();
  $args  = func_get_args();
  $query = array_shift($args); 
  $query = str_replace("%s","'%s'",$query); 
  foreach ($args as $key => $val) { 
    $args[$key] = mysql_real_escape_string($val); 
  } 
  $query = vsprintf($query, $args);

  $res = mysql_query($query);
  if (!$res) {
    trigger_error("dbget: ".mysql_error()." in ".$query);
  } else {
    while($row = mysql_fetch_assoc($res)) $a[]=$row;
  }
  return $a;
}

?>
