Version 3 — Mars 2015 — JLuc
- nom d’origine : ltaskel_truncate
- contexte de création :
J’utilise ça avec Accès Restreint et l’option define(’AR_TOUJOURS_TOUT_VOIR’, true) ;
qui permet de gérer soi-même les tests de zone, de restriction etc
Avec cette option d’accès restreint, ça ne filtre plus les boucles automatiques, on re-voit tout comme d’habitude mais dans mon squelette je peux tester avec les fonctions du plugin si un contenu est restreint
notamment avec #ID_ARTICLE|accesrestreint_article_restreint et si ça c’est restreint, alors j’affiche l’article en HTML tronqué et donc en gardant sa mise en page, y compris les images insérées, qui resteraient dans la partie non tronquée
Exemple d’utilisation : http://www.latribunedelart.com/fragonard-and-the-fantasy-figure-painting-the-imagination

* ### Options:
*
* - <span class="base64" title="PGNvZGUgY2xhc3M9InNwaXBfY29kZSBzcGlwX2NvZGVfaW5saW5lIiBkaXI9Imx0ciI+ZW5kaW5nPC9jb2RlPg=="></span> Will be used as Ending and appended to the trimmed string
* - <span class="base64" title="PGNvZGUgY2xhc3M9InNwaXBfY29kZSBzcGlwX2NvZGVfaW5saW5lIiBkaXI9Imx0ciI+ZXhhY3Q8L2NvZGU+"></span> If false, $text will not be cut mid-word
