Field is not updated

Question

I try to update a list item, with PowerShell:

try{
$root = GetRootSite #this function returns the site collection url
$site = New-Object -Type Microsoft.SharePoint.SPSite -ArgumentList $root
$customerlist = "Customer-List"
$customers = $site.RootWeb.Lists[$customerlist]

$spqQuery = New-Object Microsoft.SharePoint.SPQuery 
$spqQuery.Query =  "<OrderBy><FieldRef Name = 'ID' Ascending = 'TRUE'/></OrderBy><Where><Eq><FieldRef Name='CODE' /><Value Type='Text'>TEST</Value></Eq></Where>" 

$spSourceItems = $customers.GetItems($spqQuery)  

foreach ($i in $spSourceItems) {
$code = $i["CODE"]
write-host $code

[string]$currentlink = $i["LinkToOperations"] -as [Microsoft.SharePoint.SPFieldUrlValue]
$linktooperations = $root + "/Customers/" + $code
if ($currentlink -eq "") {


    $field = New-Object Microsoft.SharePoint.SPFieldURLValue
    $field.Description = $code
    $field.Url = $linktooperations

$i["LinkToOperations"] = $field
$i["CustomerURLText"] = "Updated"
$i.Update

write-host $i["LinkToOperations"]
write-host $i["CustomerURLText"]

}
}
$spSourceItems.Update
$customers.Update
}
catch {
    Write-Host "error" 
    $ErrorMessage = $_.Exception.Message
    Write-Host $ErrorMessage
    exit    #exit if cannot load the files above

}

Basically, if the link is empty, I want to add it. My problem is that when the code runs, the correct output is written to the console, but I don't see the results in the list. The $i object is the listitem returned by a query. I have full control on the list, no error is thrown during the process. The LinkToOperations is a url field, the CustomerURLText is text. I also get the following output upon finish:

MemberType : Method OverloadDefinitions : {System.Void Update(), System.Void Update(bool bFromMigration)} TypeNameOfValue
: System.Management.Automation.PSMethod Value : System.Void Update(), System.Void Update(bool bFromMigration) Name
: Update IsInstance : True

what am i missing?

Answer 1

Reading through your code, Update call has been used like a property without brackets. It should be a method call as :

    $i["LinkToOperations"] = $field
    $i["CustomerURLText"] = "Updated"
    $i.Update()

A URL field in SharePoint is the URL and the description. You haven't included all of your code, so I can't tell if you're accessing it wrong, but the below example (from here) should help.    

Write-Host "Adding New Link"
$field = New-Object Microsoft.SharePoint.SPFieldURLValue
$field.Description = "Microsoft"
$field.URL = "http://www.microsoft.com"
$item = $list.Items.Add()
$item["URL"] = $field
$item["Comments"] = "Added From PowerShell"
$item.Update()
