I am using JMS\Serializer in my project and I want to ignore one property only if the array in it is empty.

I tried something like :

@JMS\Exclude(if="count('$this->required') === 0")
or 
@JMS\Exclude(if="empty('required')")

but got a syntax error.

Can anyone help me on this?

thank.

  • as far as i can read the docs you can use `@JMS\Exclude(if="<1")` , could you try ? – john Smith May 01 '17 at 21:19

  • What you need was implemented recently and it is in release-1.7 so you might as well wait for [it](https://github.com/schmittjoh/serializer/releases). It is called [@SkipWhenEmpty](https://github.com/schmittjoh/serializer/pull/757/files#diff-9828fde36b4c4800e1d437a28538de94R35) This is the [bug](https://github.com/schmittjoh/JMSSerializerBundle/issues/373) related it. "`@SkipWhenEmpty` This annotation can be defined on a property to indicate that the property should not be serialized if the result will be 'empty'". – BentCoder May 02 '17 at 15:26
  • oh thank @BentCoder. it's exactly what I need. i hop it will be merged soon. – Mathieu Delisle May 02 '17 at 15:59
  • @MathieuDelisle I added it as an answer below so if you could kindly accept it, everybody else would have an idea of the possible solution. – BentCoder May 02 '17 at 16:05

@SkipWhenEmpty This annotation can be defined on a property to indicate that the property should not be serialized if the result will be "empty".

This is the bug related it.

You need this one:

@JMS\Exclude(if="!object.required")
