README
Provides an easy interface to allow Winter CMS plugins to insert HTML <meta> and <link> tags, as well as JSON-LD blocks into a layout or page. The plugin provides three helper classes to populate the meta and link tags or JSON-LD blocks, and a component each to inject them into a Winter CMS layout, partial or page file.
Usage
For theme developers
Three components are provided to inject the meta and link tags or JSON-LD blocks into your theme - metaList, linkList and jsonLdList.
Meta tags
Add the Meta -> Meta List component to your page and add the following line where you would like the meta tags to be inserted. This should preferably be inside the <head> tag.
{% component 'metaList' %}
Meta tags will be generated in the following structure:
<meta name="(name)" content="(value)">
Two options are also provided with the component:
- Include page meta?: If ticked (default), the meta title and description fields provided by Winter CMS will be also be included in the generated meta tags.
- Escape tag values?: If ticked (default), the values inserted into the
contentattribute will be escaped usinghtmlentities. If this messes up your content, you can untick this to insert the raw content instead.
Link tags
Add the Meta -> Link List component to your page and add the following line where you would like the link tags to be inserted. As above, this should also preferably be inside the <head> tag.
{% component 'linkList' %}
Link tags will be generated in the following structure:
<link rel="(name)" href="(value)">
An option is also provided with the component:
- Escape tag values?: If ticked (default), the values inserted into the
hrefattribute will be escaped usinghtmlentities. If this messes up your content, you can untick this to insert the raw content instead.
JSON-LD blocks
Add the Meta -> JSON-LD List component to your page and add the following line where you would like the JSON-LD blocks to be inserted. As above, this should also preferably be inside the <head> tag, beneath all <meta> and <link> tags.
{% component 'jsonLdList' %}
JSON-LD blocks will be generated in the following structure:
<script type="application/ld+json">
(value)
</script>
An option is also provided with the component:
- Escape JSON-LD content?: If ticked (default), the values inserted into the JSON-LD content blocks will be escaped using
htmlentities. If this messes up your content - especially in the case of HTML content, you can untick this to insert the raw content instead.
For plugin developers
If you wish to use this plugin to provide meta and link tags or JSON-LD block content on sites that your plugin is installed on, you can use the \BennoThommo\Meta\Meta, \BennoThommo\Meta\Link and \BennoThommo\Meta\JsonLd helper classes in your plugin.
These classes can be used up until the point in which the components above are rendered in Winter CMS.
Meta tags
To add a Meta tag, use the following line:
\BennoThommo\Meta\Meta::set('name', 'value')
where name is the name of the meta tag and value is the content of the meta tag.
You can also add several meta tags at once:
\BennoThommo\Meta\Meta::set([
'name1' => 'value1',
'name2' => 'value2'
]);
Note that only one value can be used per name. If the same name is used in a more recent call to the helper, the given value will overwrite any previous values.
Link tags
To add a Link tag, use the following line:
\BennoThommo\Meta\Link::set('name', 'value')
where name is the name of the link tag and value is the href of the link tag.
You can also add several link tags at once:
\BennoThommo\Meta\Link::set([
'name1' => 'value1',
'name2' => 'value2'
]);
Note that only one value can be used per name. If the same name is used in a more recent call to the helper, the given value will overwrite any previous values.
JSON-LD blocks
To add a JSON-LD block, use the following line:
\BennoThommo\Meta\JsonLd::set('name', '{key: value}')
where name is the name of the JSON-LD block and value is the JSON-encoded content you wish to use in the block.
All provided values will be checked to ensure they are valid JSON - if a value provided is not valid JSON content, an ApplicationException will be thrown.
You can also add several JSON-LD blocks at once:
\BennoThommo\Meta\JsonLd::set([
'name1' => '{key1: value1}',
'name2' => '{key2: value2}'
]);
