How do I get a $_GET['value'] in a custom hook?

I am getting a variable as $_GET['flat_id'] on the page and I want its value to ba available for a custom FormIt hook.

On the page FormIt is called as:

[[!FormItRetriever]]
[[!FormIt? 
	&hooks=`testCRUD`
	&successMessage=`Done.`
	&newFlatID=`[[!testHook]]`
]]
[[!setNewObjPlaceholders]]

Where testHook simply returns the $_GET value:

<?php
return $_GET['flat_id'];

And [[!setNewObjPlaceholders]] does nothing is the form has been submitted (so it got a value of a hidden <input>) or sets the [[fi.*]] placeholders if the page is loaded for the first time.
I'm tryibg to get the value of newFlatID in the hook as follows:

$newFlatID = $modx->getPlaceholder('newFlatID');

but $newFlatID seems to be empty.
Can anybody help?

I don't think you can get the placeholder like that... sounds like maybe you're crossing wires. You'd have to set the placeholder before you can get it.

FYI, you should filter your value -- if it's an integer, force it so it's safe:

return (int) $_GET['flat_id'];

If I'm understanding you, I think you might need to use this:

$hook->getValue('flat_id');

Normally in a script you would use the $scriptProperties['someValue']. But form it provides the $hook->getValue as Bob pointed out.

Maybe you meant

$hook->getValue('newFlatID');

Because I'm not sure that $_GET is available to FormIt hooks?

P.S. I solved my problem with a $_SESSION variable.

Thank you for help anyway!
