Hallo,
ich habe mir Captcha extension installiert, das soll automatische Spambots davon abhalten, die Formulare auszufüllen und das Gästebuch zuzumüllen.
leider verstehe ich die knappe Anleitung von Captcha nicht. Hat das schon jemand mit ve_guestbook kombiniert und kann mir kurz eine Anleitung geben, was ich tun muss, nachdem ich ve_guestbook installiert und zum laufen gebracht habe und Captcha verwenden möchte...
vielen Dank für jeden Hinweis :-)
Dade
hat noch keiner Captcha in Kombination mit ve_guestbook zum laufen gebracht ??
Wenn ja , bitte Lösung posten . Habs versucht aber bisher auch noch nicht hinbekommen !
Würde mich auch brennend interessieren. Wenn irgendjemand was in der Richtung hat ... her damit.
Das Gästebuch umsetzen dauert immer am längsten...
habe es mit der Captcha Extension von Kasper zum laufen gebracht. Hier das veränderte script:
Modern Guestbook (ve_guestbook)

zusätzlich muss im Gästebuchtemplate noch folgendes hinzugefügt werden:
###CAPTCHA_INSERT### ###FORM_CAPTCHA###
<input type="text" name="tx_veguestbook_pi1[captcha_response]" value="" class="tx-guestbook-form-inputfield-big" />
viel Erfolg damit - bei mir funktioniert es jetzt #giggle#
sagt hier bescheid, obs funzt. Achja, Freecap Extension habe ich auch ausprobiert, aber das Captchabild hat mir nicht gefallen und die Abfrage hat nicht gleich funktioniert. Im Gästebuch ist die Abfrage im Moment Caseinsesitive, kann man an der Markierten Stelle selber ändern indem man einfach die auskommentierte Zeile nimmt statt der vorhandenen...
Greets, Stonie
Sehr schön...
Ich würde auch gerne Cptcha mit dem Gästebuch verbinden...
Ich scheue mich aber etwas davo einfach die PHP Datei zu überschreiben und dann funktioniert vielleicht das restliche Gästebuch nicht mehr. Es kann ja schließlich sein, dass die Version Gästebuch Extension nicht übereinstimmt...
Vielleicht wäre es daher besser, wenn du nur den Teil posten könntest, der sich in der PHP Datei des Gästebuch geändert hat.
1. Damit das auch nachvollziehen kann
2 damit man weiß wo genau das hin gehört.
Nehme alles zurück und behaupte das Gegenteil!
Hab bei mir die beiden Code-Schnipsel eingebaut und auch den fürs Template. Klappt sehr gut!
Habe dabei noch die Farben der Grafik etwas abgestimmt und in das Formular des GB eingepflget mit einer kleinen Erklärung dazu.
Klappt auf jeden Fall sehr gut! Vielen vielen Dank dafür!
Hallo SLang, freut mich, dass Du es gebrauchen konntest. Schoene Seite hast Du. Für die anderen: der Hack ist für das "aktuelle Modern Guestbook 1.7.4" und "Captcha Library 1.0.0". Die Änderungen habe ich kommentiert, ihr koennt aber auch per cut&paste alles komplett rüberziehen wenns schnell gehen soll... viel Spass, greets, Stonie
Jo dank dir...
Falls es nochmal je,amd wissen möchte:
Der Hack läuft auch anstandslos und sofort in älteren ve-guestbook versionen, wie zum Beispiel 1.6.9
Ein Zwangsupdate ist also nicht nötig...
Bestens
Falls noch niemand gesehen hat in der aktuellen ve_guestbookversion 1.10 ist die Integration als beta vorhanden
Captcha function to avoid spamming +++ using sr_freecap +++ beta version +++ feel free to send me feedback
Ich habe die Integration aus dem Forum an Udo von Eynern geschickt und ihn gebeten , diese funktionalität als option ins Gästebuch zu integrieren ! 1 Tag später nun schon als Beta enthalten .
Also runterladen und fleissig testen und eventuelle bugs reporten !
Habs schon ausprobiert , er hat es mit sr_freecap umgesetzt , einfach extension hochladen und sr_freecap aktivieren und eventuell bei eigen verwendeten GuestebookTemplate ergänzungen aus ve_guestbook Orginal template hinzufügen

Hallo,
Da mein Gästebuch seit ein paar Wochen extrem gespamt wird (über 30 Spameinträge/Tag)wollte ich die captcha funktion einbauen komme aber nicht weiter... habe die neuste version von ve_guestbook (1.9.6) und sr_freecap (0.2.3). Das ve_guestbook Handbuch gibt keinerlei Hinweis wie man captcha aktiviert noch kann ich es im Template finden... bin für jeden Hinweis dankbar!
Gruss
SWISHI
Hallo Swishi:
ist eigentlich ganz einfach
du solltest´dir die aktuelle ve_guestbook 1.11.0 herunter laden
sobald sr_freecap installiert ist merkt das ve_guestbook und aktiviert das captcha im Template !
Du musst halt auch das neue Template aus der Version 1.11.0 nehmen!

Danke Renko für die Antwort... typo3.net da werden Sie geholfen...
Sorry, aber vielleicht steh ich auf dem Schlauch... wenn ich mich über die typo installation ins repository einlogge kommt als aktuelle version von ve_guesbook 1.9.6??? Wo gibt es die 1.11.0?
Gruss und danke
SWISHI
wer sucht der findet... ich habs gefunden! 8-)
Danke für die Hilfe an alle!

Hallo zusammen
Vielleicht kann mir ja jemand auf die sprünge helfen...
ich habe die code-schnippsel, wie gepostet abgeändert und die extension installiert.
kriege aber immernoch ca 6 spam-einträge pro stunde und da wo das bild mit dem captcha-code erscheinen sollte, kommt bei mir nur immer ein bild mit "No Spam!". #angry#
Weiss jemand vielleicht gerade abhilfe`?? ich wäre sehr dankbar!
gruss
rob
ich antworte mir mal gleich selber...:
dank dem support von hostpoint.ch habe ichs dann doch noch rausgekriegt.
das problem lag bei der berechtigung auf file-ebene. im install-tool wars so eingestellt, dass ich neue extensions mit permission 775 anstatt 755 angelegt habe.
grüsse
...und wo musstest Du das einstellen?
Habe nämlich grade das gleiche Problem.
Danke Dir für Deine Hilfe
Matthias
Ich versuche gerade ve_guestbook und sr_freecap zu installieren, allerdings finde ich nur sr_freecap 0.3.0, was aber bei meinem Typo3 3.7.0 nicht funktioniert.
Kann mir jemand eine ältere Version von sr_freecap geben?
Vielen Dank!
@ swishi
wo hast du die Version 1.11.0 gefunden? Ich hab bei mir auch nur die 1.9.6 in der Repository. Muss ich die über typo3.org runterladen?
Kann ich die irgendwie über eine vorhandenes Guestbook drüber installieren?

Hallo just2b,
vielen Dank, hat wunderbar geklappt. Jedoch noch eine Frage, ist das jetzt automatisch aktiv, also das zum Blocken von Spambots? Weil ich keine Einstellung finden konnte. Oder muss ich dazu die 1.11 nehmen? Hab jetzt die 1.12er genommen.
