This should not be removed. The legacy post templates should remain as-is, I believe. The ensure_required_markup method below does not apply for the legacy post template actions.

Hi @westonruter

Thanks for your feedback. I corrected that mistake and restored the line.

As noted below, I think this logic should be inlined (for now) as it is done above for $meta_charset and $meta_viewport and $rel_canonical below.

Since you're using $dom->createElement() here then I think it makes more sense to just do $script->setAttribute( 'type', 'application/ld+json' )

Also true. Corrected it.

Let's rename this to is_schema_org_metadata_present. But actually, I think maybe the logic should just be inlined in ensure_required_markup like the other checks are done. True that it may be better design to break up the logic into separate methods, but since the existing logic is not in methods then I don't know if we should split out this one separately.

If you changed ensure_required_markup from protected to be public and then added the logic from schema_org_present to it, along with unit tests for ensure_required_markup, then that would be great. Later we may very well want to break up ensure_required_markup into smaller methods, but I think that would probably be done along with breaking up the AMP_Theme_Support class into separate classes.

I added your suggestions.

I also did the test for ensure_required_markup, however, I only made tests for the schema.org script part. Could you use tests for the entire function?

Yes, this method needs more tests, so if that's something you want to add that would be great.

$head = $dom->getElementsByTagName( 'head' )->item( 0 );
foreach ( $head->getElementsByTagName( 'script' ) as $script ) {
if ( 1 === preg_match( '/{"@context":"https?:[\\\]\/[\\\]\/schema\.org/', $script->nodeValue ) ) {

Before looking at the content of the element ($script->nodeValue) I think it should first check 'application/ld+json' === $script->getAttribute( 'type' ).

Also, I think the 1 === should be removed. As long as preg_match() returns a truthy value that's all we really care about.

Removed the integer comparison and added your suggestion, indeed it makes it more precise.

The <script> here is missing the type="application/ld+json".

Very good observation, I added the type attribute on the new tests for ensure_required_markup()

$dom = new DOMDocument();
$dom->loadHTML( sprintf( $page, $script ) );
$this->assertEquals( $expected, AMP_Theme_Support::schema_org_present( $dom ) );
