if Template Tag
Example
Display a header if the value of the myvar variable is 1:
{% if myvar == 1 %}
<h1>Hello!</h1>
{% endif %}
Definition and Usage
The if tag allows you to write conditional statements.
Use if statements to output a block of code
if a condition is true.
You can use else or
elif (short for "else if") to specify what to
do when the if condition is false.
Example
Display one heading if myvar is 1, and
another if myvar is 2:
{% if myvar == 1 %}
<h1>Hello!</h1>
{% else %}
<h1>Greetings!</h1>
{% endif %}Example
Display a third heading if none of the conditions are true:
{% if myvar == 1 %}
<h1>Hello!</h1>
{% elif myvar == 2 %}
<h1>Welcome!</h1>
{% else %}
<h1>Greetings!</h1>
{% endif %}Syntax
{% if condition %}
