Hi all,

I have some templating system (Address Book) that only works partially.

It contains 4 files:
samplate2.php - executive file/attached/
book.php - template 1/attached/
rows.addresses - template 2/attached/
template.class

The first and the second template variable ($page_title and $letter) are set in
samplate2.php (executive file), but not the third(rows.addresses), because that variable cannot be predefined.
It get its value, after processing in address_sql function (WHILE loop).

So, first 2 variables are replaced, and third is not.

I think the defect of this code is that the $complete_table variable (from address_sql) is not forwarded to WHILE loop in
file_parser function (all from template.class) for replacement of
3.template variable {$rows.addresses} (which is the name of corresponding template file).

I need to make rows.addresses global, something like:

PHP Code:

VAR $rows.addresses = ''; 

in the global part of template.class
and subsequently:

PHP Code:

. . .

$complete_table .= $new_row;

endwhile; 

 

$rows.addresses = $complete_table; 

but this doesn't work (blank page), so I'm wondering, is the rows.addresses a valid variable name ?

Well, what can I do to forward $complete_table to replacement loop (file_parser function) but with the name 'rows.addresses' because this is the name of template variable (also of corresponding template file).

template.class

PHP Code:

<?php

class template {

VAR $files = array();

VAR $variables = array();

VAR $sql = array();

VAR $opening_escape = '{';

VAR $rows.addresses = '';

$query = "SELECT last_name, first_name, tel, email

$result = mysql_query($query);



// Open "rows.addresses" file and read contents into variable.
