texte = I wonder why you're not avoiding the use of raw contexts by using this technique instead: [showif [url][field][/url]=] .... this is shown when [fieldname] is blank ... [/showif] Of course you should be [url]ing your [field] value as in this example -- to prevent any comparison operators from screwing up your showif comparisons. By the way, when I know that the visitor cannot enter an ending webdna bracket (which would become part of the [field] value) I sometimes use this technique because it's even more efficient: [showif =[field]] .... this is shown when [fieldname] is blank ... [/showif] This works when the the [field] value does NOT have an ending bracket in it, such as in fields that are not editable by the visitor -- hidden, radio, checkbox and select -- assuming you do not put the ending bracket in one of these field values yourself! The bottom line is that I haven't used raw contexts for this purpose in years ... not that it doesn't work but it seems there are more efficient coding techniques to use in this case. But I actually think you've confused the place where you're using [raw] contexts anyways. Aren't you actually using them in your edit forms, and not on the pages that follow your form submissions? The reason I ask is because the [field] values in the page after the form submission are always going to have values, even if they are [blank] values. In other words, putting a [fieldname] tag on this page is never going to result in the raw [field] tag being displayed because that form field will always have a value that's set in the form, even if that value is blank -- unless it's a checkbox field that was not checked of course, because that's the only HTML form that does NOT get passed as a name-value pair in a form submission.
