Problem embedding html
derMicha (wagn)
I use
wagn 1.7.0, Apache, thin and MySQL. I want to embed an Google calender in a HTML
card. I tried it a few days agon successful. But now I have these
problems: That means I see sometimes the calendar. It
seems to me as it depends on the embedded code. Possible problems with
some special characters? It is for me currently a big issue, because I
had to present that on friday.
1. all embedded HTML code seems to be parsed. This parser
fails with HTML code like this:
<iframe
src="https://www.google.com/calendar/embed?height=600&wkst=1&bgcolor=%23FFFFFF&src=evli-alle%40blablablabla-blablablabl
ablabla.de&color=%232F6213&src=gev%40blablablabla-blablablablablabla.de&color=%238C500B&src=2hdr7sgtopscahqklf756e0o7kkqsrme%40import.calendar.google.com&color=%23711616&src=de.german%23holiday%40group.v.calendar.google.com&color=%23711616&src=q968q6bogn6mavg733864723n1satg4d%40import.calendar.google.com&color=%23711616&src=schulleitung%40blablablabla-blablablablablabla.de&color=%231B887A&src=p%23weather%40group.v.calendar.google.com&color=%23691426&src=e_2_de%23weeknum%40group.v.calendar.google.com&color=%23711616&ctz=Europe%2FBerlin"
style=" border-width:0 " width="600" height="600" frameborder="0"
scrolling="no"></iframe>
The error (see example) only occurs
when I creat a new card. When I paste the above HTML code in an
existing HTML card save breaks with out any displayed error message.
Nothing will be saved then.
2. When I reduce the number of embedded
calendars the parser has no problem, but the calender will not be
displayed in most cases:
<iframe
src="https://www.google.com/calendar/embed?height=600&wkst=1&bgcolor=%23FFFFFF&src=evli-alle%40blablablabla-blablablablablabla.de&color=%232F6213&ctz=Europe%2FBerlin"
style=" border-width:0 " width="600" height="600" frameborder="0"
scrolling="no"></iframe>
That problems makes it impossible to submit it as an Support Issue.
Result
when adding #1 in a new HTML card:Oops!
