Wordpress conditional statements for taxonomy, term, inside a loop not working

阅读更多关于 Wordpress conditional statements for taxonomy, term, inside a loop not working

This is such a basic problem I'm having but I've tried so many different functions and can't get any to work. On my wordpress website I have created a taxonomy called ' file-formats ' and in this taxonomy I have created these terms (I think these are terms?)... PDF , MOV , PPT and DOC See screenshot below... The problem I have which I can't seem to figure out, is I have a simple WP_Query loop, see below... <?php $downloads = new WP_Query(array( 'post_type' => 'downloads', 'order' => 'ASC', 'posts_per_page' => -1 )); ?> <?php if ($downloads->have_posts()) : ?> <?php while ($downloads->have

Dynamically changing conditions of an if statement in C#

阅读更多关于 Dynamically changing conditions of an if statement in C#

I'm working on an algorithm whose purpose is to create a collection of dates on which a certain event occurs (so that I can bold them on a MonthCalendar control, or display them in some other way). Now, for simple time intervals that can be described with regular functions (for instance if the event occurs every Monday or every 10 days) this is not a problem. The real problem occurs when I have an event with irregular occurrences (for instance if event occurs every Friday if the first day of the month is Tuesday and that kind of events). Since I can't predict the format of that condition's, or

rails - find with condition in rails 4

I recently upgraded my rails to Rails 4.1.6. This query used to work : @user = User.find(:all, :conditions => { :name => 'batman' }) Now I get this error message: Couldn't find all Users with 'id': (all, {:conditions=>{:name=>"batman"}}) (found 0 results, but was looking for 2) When I check the logs I can see that rails is trying to do a completely different query : User Load (0.4ms) SELECT "users".* FROM "users" WHERE "users"."id" IN ('all', '--- :conditions: :name: batman ') It looks like, it's trying to get all the users with the id "all" and "{:conditions=>{:name=>"batman"}}". Please help.

What's the best way to do this? I'm trying something like this, but it feels... wrong.

I've found

R - vectorised conditional replace

阅读更多关于 R - vectorised conditional replace

Hi I'm trying manipulate a list of numbers and I would like to do so without a for loop, using fast native operation in R. The pseudocode for the manipulation is : By default the starting total is 100 (for every block within zeros) From the first zero to next zero, the moment the cumulative total falls by more than 2% replace all subsequent numbers with zero. Do this far all blocks of numbers within zeros The cumulative sums resets to 100 every time For example if following were my data : d <- c(0,0,0,1,3,4,5,-1,2,3,-5,8,0,0,-2,-3,3,5,0,0,0,-1,-1,-1,-1); Results would be : 0 0 0 1 3 4 5 -1 2 3

How do I do a MSBuild Condition testing if an ItemGroup contains an item?

阅读更多关于 How do I do a MSBuild Condition testing if an ItemGroup contains an item?

问题 This should be simple, but I can't find how to do this (or maybe it's not possible). In MSBuild I have an ItemGroup that is a list of files. I want to execute a task only if a particular file is in that ItemGroup Something like: <Copy Condition="@(Files) <contains> C:\MyFile.txt" .... /> Any way to do this? Preferably without writing a custom task. Edit: The list of files is only to do with the condition. Otherwise it has no relation to the task. 回答1: Try <Copy Condition="'%(Files.Identity)'
