Template-uri in Php

 Template-uri in Php

Acum vreo doi ani am găsit clasa de mai jos pentru lucrul cu template-uri. Cred ca e cea mai simpla clasa de acest gen. Practic se parsează un fișier html unde se înlocuiesc tagurile {nume} cu un conținut setat de către utilizator. Daca nume = "Continut" atunci peste tot unde se gaseste {nume} se va inlocui cu codul html. 

Continut "tpl.class.php"

Exemplu

Un exemplu foarte simplu folosind clasa "template" arata cam asa:

include("tpl.class.php");

$header = "Header";
$meniu = "linkuri meniu";
$continut = "continut pagina";
$footer = "linkuri footer";

$tpl_pagina = &new template();
$tpl_pagina->assign(array('modul_header' => $header, 
                          'modul_meniu' => $meniu, 
                          'modul_continut' => $continut, 
                          'modul_footer' => $footer
                         )
                   );

$pagina_de_afisat = $tpl_pagina->display_template('templates/new-newsletter/interfata.tpl');
echo $pagina_de_afisat;

Template

 Conținutul interfata.tpl este o pagina normala html dar care conține următoarele variabile {modul_header} {modul_meniu} {modul_continut} {modul_footer}, care vor poziționate în website unde dorește utilizatorul. Practic posibilitățile sunt nelimitate, iar partea de html este complet deconectata de Php. Mai simplu de atat nu se poate.
O zi plăcută tuturor !
