Helpers

HtmlTag

The HtmlTag helper is used to create the root of an HTML document, the open and close tags for the <html> element.

Basic Usage

<?= $this->htmlTag(['lang' => 'en'])->openTag() ?>
<!-- Some HTML -->
<?= $this->htmlTag()->closeTag() ?>

Output:

<html lang="en">
<!-- Some HTML -->
</html>

Using Attributes

It is possible to set any attributes you require on the tag, either during the initial invocation, or via the setAttributes method:

echo $this->htmlTag()->setAttributes([
    'class' => 'no-js',
    'lang' => 'de',
])->openTag();

// <html class="no-js" lang="de">

You can also add further individual attributes with setAttribute like so:

echo $this->htmlTag()->setAttribute('frog', 'kermit')->openTag();

// <html frog="kermit">

Adding the XML Namespace for XHTML Documents

If you have configured the doctype view helper with an XHTML doctype, you can enable the relevant XML namespace on the HTML tag with addXhtmlNamespace:

echo $this->htmlTag()->addXhtmlNamespace(true)->openTag();

// <html xmlns="http://www.w3.org/1999/xhtml">

By default, the namespace will not be added, even if the current doctype is an XHTML doctype. You must explicitly enable it with addXhtmlNamespace(true).
