Web Form For Marketers 2.4 question
Situation: I'm getting technical error on a form with file upload field when form is submitted from content delivery server. Sofar I could identify that the problem happens on CD servers because there is no reference to master database. I appreciate that WFFM documenation says that FileUpload field works with master database, but at the same the documentation also mentions possibility to use "remoteWfmService". But even after configuring web service I see similar "null reference exception" in logs. Is it possible to make WFFM work without adding reference to Master database to configuration files?
回答1:
Make sure you have an entry in your connectionStrings.config called remoteWfmService on your CD server. It should look something similar to this:
<add name="remoteWfmService" connectionString="url=http://[masterserver]/sitecore%20modules/shell/Web%20Forms%20for%20Marketers/Staging/WfmService.asmx;user=[domain\username];password=[password];timeout=60000" />
See section 2.11.1 of the Web Forms for Marketers reference.
You also need to change the following setting in /App_Config/Include/forms.config file.
<!-- Sets the name of the master database -->
<setting name="WFM.MasterDatabase" value="web"/>
This isn't mentioned in the reference guide for some reason, but is looks like this same error as on this post by Alex Shyba.
