Formulare ohne .html

Hallo zusammen,
habe eine Seite (mit alternativem CMS) auf Contao umgebaut. Die Seite wurde mit Folder-URLs gebaut, ohne .HTML, ich hab die HTACCESS auch umgeschrieben und das URL-Suffix in den Einstellungen gelöscht. Seiten gehen soweit, bis auf das Formular (Seitenalias 'kontakt')
Firebug sagt: GET und POST "kontakt" -> 404

Das ist das geänderte Snippet aus der default htaccess:

Code:

---

  ##
  # By default, Contao adds ".html" to the generated URLs to simulate static
  # HTML documents. If you change the URL suffix in the back end settings, make
  # sure to change it here accordingly!
  #
  #  RewriteRule .*\.html$ index.php [L]  # URL suffix .html
  #  RewriteRule .*\.txt$ index.php [L]    # URL suffix .txt
  #  RewriteRule .*\.json$ index.php [L]  # URL suffix .json
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !contao
RewriteRule .*\/$ index.php [L]

---

Das Formular kann die action nicht routen wenn .html fehlt.

HTML-Code:

---

<form enctype="application/x-www-form-urlencoded" method="post" id="f1" action="kontakt">

---

Für GET und POST request kommt im Firebug der Fehler 404.
Auch wenn ich eine Ordner-Url wie kontakt/form als alias eintrage steht im HTML des Formulars nur action="form".

Habe das Problem jetzt erst mal so gelöst, dass ich auf der Kontakt-Seite den Alias kontakt.html eingetragen habe. Das funktioniert zwar, is aber ganz arg unschön. Hat jemand eine bessere Idee?

Danke vorab für die Hilfe.
Frohes Schaffen und Gruß, Kai

Hmm, wenn da nicht 3.5.x stehen würde, hätte ich jetzt erst mal gefragt, wie alt die Contao-Version ist. Die ".htaccess" ist ja schon eine etwas ältere Version und selbst da wohl auch nicht unbedingt Standard. Keine Ahnung ob es daran liegt oder ob das eine Beschränkung von Contao mit Formularen ist, aber du könntest eventuell mal die ganze .htaccess hier reinstellen.

Hi Tab,
die htaccess müsste von einer Contao 3.5.2 sein. Hier ist die ganze...

Die Anpassung deiner .htaccess ist falsch. Stelle die Original .htaccess.default wieder her und führe die korrekten Anpassungen danach nochmal durch: https://github.com/contao/core/blob/...s.default#L249

Zitat:

---

# If you do not want to use an URL suffix at all, you have to add a third
# line to prevent URLs that point to folders from being rewritten (see #4031).

---

->

Code:

---

  RewriteCond %{REQUEST_FILENAME} !\.(htm|php|js|css|map|htc|png|gif|jpe?g|ico|xml|csv|txt|swf|flv|mp4|webm|ogv|mp3|ogg|oga|eot|otf|tt[cf]|woff2?|svgz?|pdf|gz)$
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule .* index.php [L]

---

Poste, nachdem du das gemacht hast, deine gesamte .htaccess nochmal.

Würds jetzt mal so versuchen, was meint ihr?

Warum machst du es nicht so wie es in der Anleitung steht, bzw. so wie ich geschrieben habe? Zeile 263 sollte

Code:

---

  RewriteCond %{REQUEST_FILENAME} !-d

---

lauten. Du beschränkst es derzeit nur auf Ordner bzw. Dateien die "contao" im Namen haben.

Jupp, Du hast recht. Habs so umgesetzt. Jetzt geht auch das Formular sauber.
Vielen Dank :)
Frohes Schaffen und Gruß, Kai
