Using A Base HrefYou're probably familiar with the famous formula:
@ReplaceSubstring(@Subset(@DbName; -1); "\\" : " "; "/" : "+")
which will take the path to the current database and make it "browser-friendly".
After getting sick of adding this to every single link and image tag that needed it, we decided there had to be a better way.
Well, there is a better way
In standard HTML, in the section you can include what is called a "base" href. The tag looks something like this:
This specifies the starting poing for all relative URL's in the page, no matter if that relative URL is for a link or an image tag or anything.
How do I use this?
Well, first you place a hidden, computed for display, text field on your form called HTTP_Host. The value for this field should be HTTP_Host (no quotes - it should compute to itself).
Then, in the HTML Head section of your form, put in the following formula:
"http://" + HTTP_Host + "/" + @ReplaceSubstring(@Subset(@DbName; -1); "\\" : " "; "/" : "+") + "/"
Now you can use relative URL's on your page and you know exactly where they are coming from. For example, an image tag like <IMG SRC="myimage.gif"> will go to the current database and look for the image resource named myimage.gif.
