Extension for using Variables

Hi Guys,

I am looking for an extension which I could input the value of a variable in a back end page and replace it on the template.

Let´s say I´ve got a set of pages in my site structure:

Page Destination 1 - variable CityID = 123
Page Destination 2 - variable CityID = 423
etc..

And I want to add a variable on each of them called RegionID which I could input directly in the page structure.

I am trying with InsertTags which is the closest I get, but I need to create one InsertTag per destination which is not the idea.. since I would need to define one variable per destination page and them all on the template...

Page Destination 1 - {{CityID1}}
Page Destination 2 - {{CityID2}}

Any ideas will be greatly appreciated !!!!1

Thanks a lot !!!!

I think, custominserttags by andreas is the one...

also, you can get around this, by creating a hidden, unpublished page (so its still editable) and then having articles or CE's defined with the variable contents and then simply referring them using standard inserttags

{{insert_content::5}} where 5 is the CE's ID number.
{{insert_article::8}} where 8 is the Articles ID number.

This is a clever way I use it to insert the Header and Footer contents are modules, but remain editable as elements by the client (e.g. copyright, etc.).
