NAME

Dotiac::DTL::Tag::for - The {% for VARIABLE1[|VARIABLE2[|VARIABLE3[|...]]] in VARIABLE %} tag

SYNOPSIS

Template file:

{% for x in arrayloop %}
	{{ forloop.counter }}: {{ x }}
{% endfor %}
{% for x in hashloop %}
	{{ forloop.revcounter }}: {{ x }}
{% endfor %}
{% for key,value in hashloop %}
	{{key}} is {{ value }}
{% endfor %}
{% for x,y in arrayofarrayloop %}
	X = {{ x }}, Y = {{ y }} 
{% endfor %}
{% for x in emptyloop %}
	{{ forloop.counter }}: {{ x }}
{% empty %}
	The loop is empty
{% endfor %}

Perl-file:

$t=Dotiac::DTL->new("page.html");
$t->print(
	{
		arrayloop=>[1 .. 10],
		hashloop=>{A=>1,B=>2,C=>3,D=>4},
		arrayofarrayloop=[[1,10],[2,20],[3,30]]
	});

DESCRIPTION

Iterates over a datastructure, assigns the variable to every element of an array or hash and runs the included templatecode with it.

If the loop is empty and an {% empty %} tag is given, it will run the templatecode from {% empty %} to {% endfor %}.

If given one variable to assign with a hash, it will set it to the value, if given two, it will assign the key to the first and the value to the second variable.

If given more than one variable and a array of arrays, it will assagin the variables to the hash content.

the forloop variable.

Inside a loop, these variables are set:

forloop.counter

forloop.counter0

The current iteration of the loop, starting with 0.

forloop.revcounter

The remaining iterations, starting ending with 1.

forloop.revcounter0

The remaining iterations, starting ending with 0.

forloop.first

True if this iteration is the first one.

forloop.last

True if this iteration is the last one.

forloop.parentloop

In nested loops, this is the one above the current
