Hello, I have a problem to assign a variable in the dtml-in tag.

You certainly have if you think that's what you are doing in yuour code fragment below.

If I use the following code, I can get the expected result.

<dtml-in "test('/temp/1063')"> <a href="description_html?file=/temp/<dtml-in Inspector_Name><dtml-var UserID></dtml-in>/<dtml-var sequence-item>"><dtml-var sequence-item><br> </dtml-in>

You are trying to write a collection of html "a" elements, not assign any variables. Now, setting that aside, if this is the only code it is mal-formed because there are more </dtml-in> than <dtml-in> tags. You need to start with what you want to accomplish, and then make sure all the pieces work right. For example, dtml-in will loop through the database result set. Is that what you want? If it is, then does Inspector_Name work as expected? And so on. If you know what works and what does not, make sure you include the information when you ask for help. Once all the parts work, try something as simple as possible, and extend it until you encounter a failure. In this case, we don't know if there is an outer dtml-in loop, so it's hard to know wht to say.

However, I want to get 1063 in line 1 from <dtml-in Inspector_Name><dtml-var UserID></dtml-in>, just like line 2, I failed. "Inspector_Name" is a ZSQL-method, to retrieve the UserID from the database by using the login name. "test(path)" is the external method to get the actual files name and directories name in the ext2 file system of Linux.

I tried to use <dtml-in "test('/temp/<dtml-in Inspector_Name><dtml-var UserID></dtml-in>')"> instead of line 1. I failed.

Of course. You can't embed one dtml tag in another, and there is never any reason to try. Once you are inside a dtml element, the Zope variables and properties are available - you don't need to open another tag to get at them. Cheers, Tom P
