Trapping MvCALL error

Hello experts.

I want to call a page by MvCALL - different server, maybe an .htm maybe an
.asp. If the page is there and I can get to it I would like it to display,
hence <MvEVAL EXPR="{callvalue}">

But if the page is gone or unavailable I want it to generate a handlable
variable (err1) and NOT show the error message and not kill the script.

I've tried 20 variations of the below code (more, less, different). I don't
do a lot of error trapping and this seems to be getting the best of me. Any
help out there. (this is non-compiled by the way).

Thanks

Trapping MvCALL error



Hi Keith,

You had a typo (nondisplay instead of nodisplay)

Try this (I used a non-existant domain for testing):

<MIVA MvCALL_ERROR="nonfatal,nodisplay">

<MvCALL ACTION = "<A HREF ="http://www.tyrinth6.org" METHOD = "get" FIELDS = "">">http://www.tyrinth6.org" METHOD = "get" FIELDS = ""></A>
</MvCALL>

<MvIF EXPR="{ MvCALL_ERROR }">
ERROR ERROR!



</MvIF>

Trapping MvCALL error



Hi Keith,

One simple way is to include into the MvCALL a condition that triggers an
MvCALLSTOP when a server error occurs, a bit like this :

<MvASSIGN NAME="err1" VALUE="">
<MvCALL
ACTION=<A HREF ="http://www.pageIwant tofind.com/dosomething.htm">http://www.pageIwant tofind.com/dosomething.htm</A>
METHOD="post">

<MvIF EXPR="{ 'HTTP 404' CIN callvalue OR 'HTTP 500' CIN ....
etc.etc.etc. }">
<MvASSIGN NAME="err1" VALUE="1">
<MvCALLSTOP>
<MvELSE>
<MvASSIGN NAME="g.pagecontent" VALUE="{g.pagecontent$callvalue }">
</MvIF>

</MvCALL>

<MvIF EXPR="{ NOT err1 }">
<MvEVAL EXPR="{ g.pagecontent}">
</MvIF>
