Save state between page views? - Joomla! Forum - community, help and support

are there methods in joomla 1.5 framework can use save state between page views? typically, user fills in number of forms , want save input fields before all pages have been walked through (a kind of page-by-page wizard) , everything's submitted database. can use "user" object purpose? is possible retrieve user object jfactory::getuser() , then ... there member can use save data in associative array perhaps? or there other prefered methods save state (temporary storage)? thanks mike Board index Joomla!

Le Programmateur Horaire nouveau est arrivé

bonjour, cette nouvelle version totalement refondue permet de mettre en route et d'arrêter jusqu'à 6 appareils électriques selon des plages horaires prédéfinies pour chacun des appareils. suite aux suggestions qui nous ont été faites, la grande nouveauté est l'utilisation du keypad du shielkd lcd pour la mise à jour de l'heure du ds 3231, de la date et des plages horaires. le prototype décrit pilote 4 voies, cependant il peut être facilement étendu à 6 voies en apportant une modification mineure au programme et en ajoutant une carte 2 relais. on trouvera le dossier complet à cette adresse : https://1drv.ms/b/s!ai8dyckrlbvuibddrnhmw7vgzitc le programme été écrit de telle sorte que l'on puisse récupérer le module mise à l'heure du ds3231 et ses variables pour l'utiliser dans une autre application. cordialement bonjour, merci pour votre partage, beau travail. est-il possible de programmer plusieurs plages horaires par voie/24 heur...

hi, ich bin bzgl. meiner alarmanlage bei dem punkt angekommen, dem ich mir überlegt habe, dass ich im ganzen haus verteilt gerne pir-sensoren per wlan einbinden möchte. hab vor kurzem etwas irgendwo gelesen über wlanmodule, bei denen bereits ein arduino mit bord ist. weiss nicht, ob das sinn machen würde. ich würde mich dieser stelle auch über alternative vorschläge, eure erfahrungen und/oder links zu vergangenen threads ähnlichen kalibers freuen. diese thematik wurde doch hier bestimmt bereits vertieft.. mir fehlt halt einfach noch ein wenig der passende input.  gruß chris jammer quote wlanmodule, bei denen bereits ein arduino mit bord ist ?  ?  ? nodemcu !

bonjour et bonne année à tous, j'ai utilisé un pro mini pour modifier une télécommande 433 mhz sans fil qui à l'origine commute un relais à l'appui sur un unique bouton. le relais décolle au relâché du bouton. a partir de 30 m du récepteur, la commande est aléatoire et le relais se ferme et s'ouvre plusieurs fois sur une commande d'une durée de 2 secondes environ. cela fonctionne ainsi jusqu'à une centaine de mètres, endroit ou je désire commander une pompe avec un appui pour marche et un autre appui pour arrêt. sur la carte récepteur, j'ai séparé la sortie du circuit intégré décodeur > pin2 du pro mini, du transistor commandant le relais > pin4. l'impulsion fait 5 v, donc compatible arduino. c'est tout bête me direz-vous en temps normal, le µp est endormie (consommation 3.5 ma). j'ai prévu une mise en marche de la pompe au front montant de la première impulsion, suivi d'un verrouillage de l'entrée pendant 4 secondes. le ...
