CakePHP Canonical Tag with html helper
How can I create this using the html helper? (with inline=false so i c开发者_如何学Pythonan specify it on a per-view basis)
<link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" />
Can't seem to find anything on this, apart from a patch that doesn't work.
Found this in CakePHP bugtracking site : http://cakephp.lighthouseapp.com/projects/42648/tickets/1063-support-for-custom-meta-tag-elements-in-htmlhelper
Apparently you can use
echo $this->Html->meta('canonical', 'http:://example.com', array('rel'=>'canonical', 'type'=>null, 'title'=>null));
//outputs <link href="http:://example.com" rel="canonical" />
It seems my friend just told me that I told him how to do this a few months back, problem solved...
<?php echo $this->Html->meta('canonical',
'http://www.example.com/product.php?item=swedish-fish',
array('rel'=>'canonical', 'type'=>null, 'title'=>null, 'inline' => false)
);?>
If you're looking for something that automatically outputs the current url into a canonical tag, you can use the $this->Html->url(null, true); or $this->here; within the Cakephp html helper.
<?php echo $this->Html->meta('canonical', $this->Html->url(null, true), array('rel'=>'canonical', 'type'=>null, 'title'=>null)); ?>
Or
<?php echo $this->Html->meta('canonical', $this->here, array('rel'=>'canonical', 'type'=>null, 'title'=>null)); ?>
WARNING:
I have heard of some cases where $this->here has issues on local dev environments.
In CakePHP 2:
echo $this->Html->meta('canonical', 'http://example.com', array('rel' => 'canonical', 'type' => null, 'title' => null, 'inline' => false));
In CakePHP 3:
echo $this->Html->meta('canonical', 'http://example.com', array('rel' => 'canonical', 'type' => null, 'title' => null, 'block' => true));
Note that the main difference between versions is that CakePHP 2 uses 'inline' => false whereas CakePHP 3 uses 'block' => true to place these within the document <head> tags.
In CakePHP 4:
In your view (es: Articles/view.php) add this:
<?php $this->Html->meta(
'canonical',
Router::url(['controller' => 'Articles', 'action' => 'view', $article->slug], true),
[
'block' => true
]
);
?>
Then you print it in your layout/default.ctp with this instruction
<?= $this->fetch('meta') ?>
加载中,请稍侯......
