Feature Requests item #543468, was opened at 2002-04-14 05:21 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=403614&aid=543468&group_id=31885 Category: None Group: None >Status: Closed Priority: 1 Submitted By: Dipl.-Inform. Kai Hofmann (powerstat) >Assigned to: Richard Archer (richardarcher) Summary: unset_var for template.inc! Initial Comment: Please add a method unset_var("varname/array") to the template engine. This is required when handling blocks within blocks!!!! Because in this situation you have sometime to clear already set variables! Blocks within blocks can be very power- and helpfull but one ran into strange situations when no unset_var is available. Its 5 Minutes of work or less! Thanks. ---------------------------------------------------------------------- >Comment By: Richard Archer (richardarcher) Date: 2002-07-12 08:42 Message: Logged In: YES user_id=279311 I've added clear_var method which sets the value of an variable (or array of variables) to "". Also added an unset_var method which unsets the variable completely. Use whichever seems appropriate. This is in the CVS only at this stage. I also merged the -devel version of template.inc into the -stable tree. I'm tired of maintaining two versions. ---------------------------------------------------------------------- Comment By: Layne Weathers (layne_weathers) Date: 2002-07-06 03:03 Message: Logged In: YES user_id=278685 You're correct, there are 2 different issues here. In the case of embedded blocks, setting the variable to "" is adequate because the variable is going to be reused immediately - there's no need to destroy it and then recreate it. On the other hand, I often use 2 Template instances to minimize the variables parsed during long loops - in this case I always do a full unset between loops. FWIW, I discovered some less-than-ideal programming and variable use when using an actual unset; setting the variable to "" covered the problem up. ---------------------------------------------------------------------- Comment By: Dipl.-Inform. Kai Hofmann (powerstat) Date: 2002-07-04 19:27 Message: Logged In: YES user_id=286352 Sorry to say, but my experience shows that it is not a simple set_var("name","") because this is different from a real unset() ! ---------------------------------------------------------------------- Comment By: Layne Weathers (layne_weathers) Date: 2002-04-16 01:13 Message: Logged In: YES user_id=278685 A unset_var() (or clear_var() as I use in my personal extension) is simply an alias for set_var("varname", ""). Someone may get around to adding such an alias to the official library, but it is far less urgent than many existing bugs. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=403614&aid=543468&group_id=31885 |
