Sitecore provides an amazing field back functionality to manage the fallback for multi-language websites. In the previous version 7.2, we needed to install the fallback module as a separate module but in the versions 9 and 10, we have it as an inbuilt functionality to manage such activities.
In our latest upgrade project, the version 7.2 field fallback module was used so when we started the upgradation, we found a lot of dependency. We faced challenges for upgradation whereas in the versions 9 and 10, we were able to use the inbuilt fallback features.
In order to use the language fallback, you need to enable either the item-level or the field-level fallback on the relevant sites, items, fields or templates.
In addition to that, on the relevant language definition items, you have to specify the fallback language that determines which version of an item or field is there that you want displayed when there is no version available in the current language.
<patch:attribute name="enableItemLanguageFallback">true</patch:attribute> <patch:attribute name="enableFieldLanguageFallback">true</patch:attribute>
But when we upgrade the project, templates are already created so we have to manually or automatically enable item and field level fallbacks. Please refer to the below PowerShell script for the automatically enabled field and item-level fallbacks.
Below I have mentioned the PowerShell script for enabling field fallback in Sitecore. While you run the script it would target the particular template node and it would check the field fallback and item fallback checkboxes in template items and enable field fallback functionality for items which are created based on those templates.
$sourcePath = "web:/sitecore/templates/project/ABC"
$items = Get-ChildItem -Path $sourcePath -Recurse
$rootItem = Get-Item -Path $sourcePath
$items = $items + $rootItem
foreach($item in $items){
Write-Host $item.ID $item.Name
if ( $null -ne $item.Fields["__Enable Item Fallback"] -and $item.Fields["__Enable Item Fallback"].Value -ne "1")
{
$item.Editing.BeginEdit();
$item.Fields['__Enable Item Fallback'].Value = '1'
$item.Editing.EndEdit();
Write-Host $item.ID $item.Fields["__Enable Item Fallback"].Value $item.Paths.Path
}
}
$sourcePath = "web:/sitecore/templates/project/Blog"
$items = Get-ChildItem -Path $sourcePath -Recurse
$rootItem = Get-Item -Path $sourcePath
$items = $items + $rootItem
foreach($item in $items){
Write-Host $item.ID $item.Name
if ( $null -ne $item.Fields["Enable Shared Language Fallback"] -and $item.Fields["Enable Shared Language Fallback"].Value -ne "1")
{
$item.Editing.BeginEdit();
$item.Fields['Enable Shared Language Fallback'].Value = '1'
$item.Editing.EndEdit();
Write-Host $item.ID $item.Fields["Enable Shared Language Fallback"].Value $item.Paths.Path
}
}
Once you performed the above script in Sitecore, now language field fallback checkbox is ticked and your fallback functionality will work smoothly.
