The first field name syntax can be used to update only 1 Tag per form, while the second syntax can be used if it is required to update more than
one Tag at the time. With the second syntax, the number of Tags that may be updated with one FORM is not limited. The eWON will check items
with an increment of 1 until not found.
Note:
If TagName1, TagName2 and TagName4 are defined, only TagName1 and TagName2 will be updated because TagName3 is
missing.
WARNING:
The "ResultPageOk" URL must be specified from the eWON root: i.e.: /usr/xxxx
TagName Is a form field that will define the name of the Tag to update. Usually it will be a hidden field.
TagValue
Is a field that will hold the new value of the Tag. This may be a list box or a text edit field or any other type, and its
initial value may be filled with a TagSSI (see examples), or maybe with a TagSSI and Java Script in case of list box.
ResultPageOk
Is a field that is also usually hidden. This field is optional and defines the page to show when the update has been
performed.
