Aha! Moments

[DaveP]

"A moment of sudden realization, inspiration, insight, recognition, or comprehension." (Merriam-Webster)

(Nothing to do with these guys.)

You are cordially invited to share your PW Aha! moments here. Hopefully others will benefit.

For instance, the project I am currently working on includes a form to allow the entry of televised football fixtures (Time/Date, Home team, Away team). This is implemented as a PageTable and I needed to list any lines already existing and a blank line to allow the entry of a new fixture. foreach-ing through the existing fixtures is easy, but how to cleanly (in programming terms) add a blank line?

$a->makeBlankItem()!

$fixtures = $pages->find("template=fixture");
$emptyFixture = $fixtures->makeBlankItem();
$fixtures->append($emptyFixture);

foreach($fixtures as $fixture){
    ...do stuff..
}

And that will include a blank fixture at the end. The ...do stuff... will very likely be form inputs.

(I know a couple of lines could be chained (okay, 1-3), but it reads easier to me as it is.)

Sorry, I tried to read this in an Alan Partridge style voice and it came out very strange!

That connection never even occurred to me! (#accidentalpartridge)

Isn't this a "pub" topic?

[DaveP]

@Nico I did wonder about that but since it is directly about PW, I put it here. That said, if any mod wants to move it, then go ahead.
