Thumbnails from Images that are linked already uploaded to the CMS

<%
' make sure WYSIWYG images don't get too wide using upload.asp
value = content.item("_cmsUploadValue")
debug.write(value)
ext=filename.getextension(content.item("_cmsUploadValue"))
' create a medium size thumbnail
if ext="gif" or ext="jpg" then
res = image.thumbnail(value, "", 20, 20)
if res = "" then
content.add "_cmsError", image.errorMsg
exit Sub
end if
content.add "upload#my_photo", res
end if


%>


Then in the post_input.asp we would have the code that would be used to
create thumbnails from images that are linked:

<%
value = asset.getAbsoluteName(content.item("my_photo"))
debug.write(value)

'Process only if selected asset has been uploaded to the /Assets/
folder in the CMS
if instr(value, "/Assets/") > 0 then

value = "/ChemicalHeritage/ftproot" & value


ih = image.load(value)
if ih <0 then
content.add "_cmsError", image.errorMsg
exit Sub
end if

image.scale ih, 20, 20, 1
image.setQuality 1
content.add "upload#my_photo", image.saveAsAttachment(ih,
content.item("_cmsId"), "_thumbnail")

end if


%>

Checking / Creating New Folders from an SMTP Import

To check if a folder exists in the CMS already you have to create a folder list. There is no direct commands to do this. dim folderExists folderExists = false set folderlist = asset.getFolderList("/path/") 'loop through folder list do while folderlist.nextEntry() if folderlist.item("_cmsLabel") = "foldername" folderExists = true exit do end if loop To create a folder in the CMS, first make a Model that only contains a folder. Then do the following: if folderExists = false then 'create folder set dict = system.createDictionary() fId = asset.create(folderName, "/Site/Global/Picture of the Week/", "/System/Models/Directory Builder", dict) end if The parameters for the asset.create("label", "Path", "Model to use", content or dictionary)

Questions about Outages

Routine CMS maintentance windows are from 6pm - 7pm, every Monday and Wednesday. Generally, the system is still available during these times, but may be unavailable for a few minutes during that period. There are other times where maintenance must be performed outside these windows due to unforeseen circumstances. We aim to provide as much notice as possible for these events, typically via email and via an alert on the login page. The routine maintenance is also mentioned on the login page on the day of maintenance.

Making references to Assets work even if the Asset has not been published yet

In the CMS, from within the current asset if you have a link to another asset and the other asset has not been published yet. The current asset will have the link disabled when published. In some cases even content will not be displayed as well. To prevent this from happening you can use this trick: asset.setPram "filter_status", "*" href = asset.getLink("path or id") Now the href will be enabled regardless of whether the asset being reffered to has been published or not.
