Hide intro if no data

[FilMar]

How can I best hide the intro when there is no data?

I have a list that is shown in the outro of a form, but I want to hide it all the way when there is no data to show.

For the data part it is ok, I have deleted the headings in the template.
But I have some text in the intro that I also want to be hidden if there is no data to be shown.

I tried with
if ($this->rows !=0) {
echo $this->table->intro;
}

and some other variations but it still shows

Many thanks in advance,

Filip

$this->rows is an array.
Try
empty($this->rows)

!empty($this->rows) did not work

but
!empty($this->rows[0]) seems to work.

Thanks,

Filip
