What is snippetArea without parameters used for?

[ikeblaster]

@dg We used it to solve Dynamic snippets are allowed only inside static snippet/snippetArea.

Of course we can use {snippetArea xyz}, it works without any problems (and we have done that in our code). But it's still a minor BC issue.

---

More detailed example - not particularly elegant, but it worked for the desired result (redrawing individual controls in AJAX calls). If there is a better solution (which would cover all our needs), we haven't found it yet.

_blocks.latte

{define form $formName}
	{snippetArea}
		<form n:name="$formName" class="form-layout">
			<div n:foreach="$form->getControls() as $name => $input"
					n:snippet="$input->htmlId">

				{* custom controls rendering *}
			</div>
		</form>
	{/snippetArea}
{/define}

edit.latte

{import '_blocks.latte'}

{snippetArea exampleForm}
	{include form exampleForm}
{/snippetArea}

fixed

Btw, I also removed exception ''Dynamic snippets are allowed only inside static snippet/snippetArea.' in 2.9-dev 77d4498 according to this issue #134. @matej21 is it safe?

[matej21]

@dg i think, you won't get any runtime error, so it might be harder to understand why it doesn't work.

[dg]

I don't understand snippets at all (No longer) :-) So have I remove (#134 (comment)) or keep the check?

[matej21]

@dg imho the check is not needed anymore for dynamic snippets to work, but it might be a useful hint for developer. The runtime check/hint could be implemented in snippet driver when renderingSnippets is false
