Template Wahl

[Konto]

Wie kann man den User mehrere Templates zur Wahl stellen? Normalerweise kann man doch nur 1 Template pro Seite einstellen.

[Piratos]

das es hier etwas gutes gibt ist mir nicht bekannt

Die letzte CMS war meine eigene, die das perfekt gelöst hat, aber die habe ich verkauft.

Wie kann man den User mehrere Templates zur Wahl stellen? Normalerweise kann man doch nur 1 Template pro Seite einstellen.

Das ist 'ne gute Frage ...

Da die CSS in der Datenbank abgelegt ist, könnte ich mir vorstellen, dass sich da eine Datenbankabfrage zur Umschaltung des Stylesheets programmieren läßt. Da ich aber kein Coder bin, schau mal hier:

http://forum.cmsmadesimple.org/index.ph ... l#msg11351

Piratos hat da beschrieben, wie man das Template und das CSS extern "lagert". IMHO könnten auf diese Weise auch Scripte zum CSS-Switching, wie man sie von statischen Seiten kennt, wieder zum Einsatz kommen .

Gibt es diesen Thread (
http://forum.cmsmadesimple.org/index.php/topic,2090.msg11351.html#msg11351) auf deutsch? Oder ein Tutorial.

        <h3>What does this module do?</h3>
        <p>It provides an interface for users to switch stylesheets. The stylesheets it uses are the selection of additive stylesheets that are located under Content > stylesheets.</p>
        <h3>How should I use it?</h3>
        <p>There are two ways to integrate this page into the front end, both represent themselves as standard tags, so you use {cms_module module=\"stylesheetswitcher\"} with any of the arguments below.</p>
        <h3>What parameters are there?</h3>
        <p>There are a couple of tunable parameters:<br />
                 <ul>
                     <li><strong>use_javascript</strong> <em>[true|false]</em> Set this styleswitcher to use AJAX in compliant browsers. <strong>not implemented yet</strong></li>
                     <li><strong>format</strong> <em>[selector|summary|summary_link|link]</em> This can have three valid values: 'selector' will display a page content that allows a user to select a selection of page styles (ie more than one). 'summary' displays a smaller drop down that is suitable for inline display ('summary_link' displays the same drop down with a link to a copy of the output from 'selector'). 'link' provides a link to a page containing 'selector'</li>
                 </ul>

Ich würde dieses Modul überhaupt nicht verwenden.

[Konto]

Ne? Gibt es was besseres?

[Piratos]

Für diese Dinge  könnte man hervorragend mit Smarty arbeiten, einfach schnell und billig.

[cyberman]

Könnte mir jemand vielleicht die Auswahl in einem Dropdownfeld machen?

Versuch's mal so:

Code: Select all

{cms_module module="stylesheetswitcher" format="summary"}

Stimmt, aber es gibt Leute, die Smarty nicht verstehen. Ich sehe es so: fuer Programmers, gibt's ein Ansammlung Methodenlehren, und fuer Endbenutzer gibt's ein andere Ansammlung.

(Wie immer, entschuldige mich ich fuer mein schlecht Deutsch.)
