Smarty einrichten
Sunday, 23 December 2007
Für mein neues Projekt habe ich mich dazu entschlossen, Smarty zu benutzen.
Smarty ist – kurz gesagt – eine PHP-Klasse mit der man PHP-Code und HTML trennen kann.
Es ist grundsätzlich sinnvoll, die lib-Dateien nicht in das library-Verzeichnis von PHP zu kopieren, sondern sie in den Projektordner zu kopieren.
Gegeben ist der Projektordner “balduin” welcher folgende Ordnerstruktur bekommt:
/balduin/inc/ /balduin/lib/ /balduin/php/ /balduin/tpl/ /balduin/tpl_c/
In dem inc-Ordner kommen später Konfigurationsdateien rein, zum Beispiel die Zugangsdaten für die Datenbank.
In dem lib-Ordner kommen die Dateien rein, die im lib-Ordner von Smarty drin sind (siehe INSTALL).
Der php beinhaltet die php-Dateien. Er kann nach eigenem Gutdünken benannt werden.
Im tpl-Ordner sind die Templates (HTML) Dateien drin.
Ich habe im tpl- und im php-Ordner jeweils noch weitere Ordner erstellt, also in diesem Fall ein Ordner für die Startseite (namens “index”):
/balduin/php/index/ /balduin/tpl/index
Darin befindet sich eine index.php bzw. index.tpl.
index.php
<span style="color: #000000">
<span style="color: #0000BB"><?php<br />$s</span><span style="color: #007700">-></span><span style="color: #0000BB">assign</span><span style="color: #007700">(</span><span style="color: #DD0000">"test"</span><span style="color: #007700">, </span><span style="color: #DD0000">"value"</span><span style="color: #007700">); </span><span style="color: #FF8000">// Deklarierung der Variable $test mit dem Wert "value"<br /></span><span style="color: #0000BB">$s</span><span style="color: #007700">-></span><span style="color: #0000BB">display</span><span style="color: #007700">(</span><span style="color: #DD0000">"index/index.tpl"</span><span style="color: #007700">); </span><span style="color: #FF8000">// Pfad zur dazugehoerigen Template-Datei<br /></span><span style="color: #0000BB">?></span>
</span>
<span style="color: #0000BB"><?php<br />$s</span><span style="color: #007700">-></span><span style="color: #0000BB">assign</span><span style="color: #007700">(</span><span style="color: #DD0000">"test"</span><span style="color: #007700">, </span><span style="color: #DD0000">"value"</span><span style="color: #007700">); </span><span style="color: #FF8000">// Deklarierung der Variable $test mit dem Wert "value"<br /></span><span style="color: #0000BB">$s</span><span style="color: #007700">-></span><span style="color: #0000BB">display</span><span style="color: #007700">(</span><span style="color: #DD0000">"index/index.tpl"</span><span style="color: #007700">); </span><span style="color: #FF8000">// Pfad zur dazugehoerigen Template-Datei<br /></span><span style="color: #0000BB">?></span>
</span>
Um die gerade deklarierte Variable auszugeben, reicht es, folgendes in die index.tpl zu schreiben:
{$test}
Aufgerufen wird alles über die index.php im Projektordner, welche folgenden Inhalt benötigt:

In diesem Fall habe ich ausser der index- Datei noch eine test-Datei.
