Add List Item to Remote Sharepoint 2007 using Powershell - web-services

Question

I am attempting to automatically add records to a list in Sharepoint. I am following along in this post
http://blogs.msdn.com/b/powershell/archive/2010/06/24/using-new-webserviceproxy-to-get-modify-and-add-items-to-a-list-in-sharepoint-2007.aspx
but keep receiving an error.
Code to date:
$packet = [System.Xml.Linq.XElement]::Parse(#"
<Batch OnError="Continue" ListVersion="1">
<Method ID="1" Cmd="New">
<Field Name="Checked At">2006-1-11T09:15:30Z</Field>
<Field Name="Cold">0</Field>
<Field Name="Inbox">0</Field>
</Method>
</Batch>
"#).Root;
$uri = "http://.../_vti_bin/Lists.asmx";
$listName = "Daily Check";
$lists = New-WebServiceProxy -Uri $uri -UseDefaultCredential;
$lists.UpdateListItems($listName,$packet);
This keeps returning the error:
Exception calling "UpdateListItems" with "2" argument(s): "Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown."
At line:14 char:1
+ $lists.UpdateListItems($listName,$packet);
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There doesn't seem to be much other information in the error message.

It appears that read methods are OK, but write is causing the error. Unfortunately, there just isn't enough information about the error to action it.

Answer 1

Your code seems to be fine except that you are sending the name of the list in parameter 1 to updatelistitems. We have similar code, but we use the listid in the first parameter.
To get the id of the list from the name of the list, do the following.
$listidandviewid = $lists.getlistandview($listname, "")
$listid = $listandviewid.childnodes.item(0).name
if you want the viewid as well you can also use.
$viewid = $listandviewid.childnodes.item(1).name
Then finally use the listid
$lists.UpdateListItems($listid,$packet);
Hope it works out for you!
