I want to use for loop in a Velocity view. I want to take a counter variable in velocity view and loop till it equals. e.g

counter = 3
for(i=0; i< counter; i++){

...

}

Alex's answer works fine, but do note it loops 4 times total because the start and end are inclusive in a Velocity #foreach loop. Another way to do it if you want a zero-indexed loop and have an exclusive end value, is to use the builtin $foreach.index. If you want to loop $n times:

#foreach($unused in [1..$n])
    zero indexed: $foreach.index
#end

here, $unused is unused, and we instead use $foreach.index for our index, which starts at 0.

In the question's case, $n is 3.

We start the range at 1 as it's inclusive, and so it will loop with $unused being [1, 2, 3], whereas $foreach.index will be [0, 1, 2].

See the user guide for more.

You can use foreach for this, by defining a range and iterating over it.

#set($start = 0)
#set($end = 3)
#foreach($i in [$start..$end])
   ...
#end
