Velocity and $foreach.count

Question

I am using velocity 1.7 and within a foreach loop I want to print the count. In the template I have the following string in a #foreach/#end section:

Count: $foreach.count

and was expecting to see in the rendered result something like

Count: 1
...
Count: 2
...

but all I see is:

Count: $foreach.count
...
Count: $foreach.count
...

Any ideas what am I doing wrong?

Solution 1

Your code is partial, we don't see the foreach directive.

Else, I know that the foreach loop has a built-in variable called $counter, though in the guide they do refer to $foreach.count

Solution 2

Neither $foreach.count nor $counter worked for me.

This answer suggests using $velocityCount, and it worked for me.

Solution 3

I tried with $counter & $foreach.count but neither of these worked for me.

However, the $velocityCount tag worked and below is the example.

Input code:

#foreach($entry in $entries)    
    <p>In for Loop count is : $velocityCount</p>     
#end    

Output:

In for Loop count is : 1

In for Loop count is : 2

In for Loop count is : 3

Solution 4

I do not know why the foreach loop built-in variable called $count is not working as guide refer. But $velocityCount is worked for me.

There is property called directive.foreach.counter.name is velocityCount in velocity.properties file, so default $count variable may not be working.

Solution 5

k.honsalis answer is deprecated.

At this point you can only use $velocityCount, even though the documentation will refer to deprecated methods.

#foreach($item in $items)
counter 0: $foreach.index
counter 1: $foreach.count
counter 2: $counter
counter 3: $velocityCount
#end

Output:

$foreach.index
$foreach.count
$counter
1

can you please add the complete foreach statement?

In Velocity < 1.7 there was a way to configure the name of the counter variable using "directive.foreach.counter.name = velocityCount" in the properties that initialized the engine (this was from the default version). It looks like they've removed the ability to do that change and have named it specifically ${foreach.counter}.

I'm used to using the formal notation ... a little more verbose but for the most part exposing clarity.

This worked for me too. We are using velocity 1.5 and due to using third party framework we can not move to 1.7

I am using velocity engine 2.1 and ${foreach.count} works.

This answer makes more sense. Thanks!
