Question

How to check if headTitle is already used?

To avoid appending or overwriting existing title, which was set earlier in parent views/layout.

Thanks 😉

Update

Example:

$this->headTitle('First title'); // index.phtml
$this->headTitle('Second title'); // some-nested-tpl.phtml

Check whether First title is set and assign Second if not.

Answer 1

You can simply check the content of headTitle and if it’s the default then write something else like:

if($this->headTitle() == '<title></title>') {
  $this->headTitle('foo')
}

Or write yourself a view-helper to safe yourself some writing time and have a function like

$this->headTitleIfEmpty('foo');

which does the above, so you have a short tag in your templates.
