VZ URL Fieldtype for Craft

Version 1.0.2 requires Craft 2.5 (currently in beta). For Craft <= 2.4 compatibility, please download version 1.0.1.

A VZ URL field displays a textbox where the user can enter a URL. It will ping the URL they entered and display an error message if it doesn't find a valid webpage there. It also prompts the user to update URLs that are redirected to a different location.

Please note that VZ URL will not prevent the user from saving their entry if if cannot validate the URL - it just warns them. This is intentional, perhaps they are linking to a page they have not yet created, or the site they are linking to is currently down but they know the URL is correct.

Template Variables

Simple output

Just output the URL that was entered.

<a href="{{ entry.fieldName }}">Link</a>

Redirect

Immediately redirects a visitor's browser to the specified URL. Any other code in a template containing this tag will never be displayed.

{% redirect entry.fieldName %}

URL Parts

A helper function, craft.vzUrl.parse makes available an array of all the pieces of a URL. Keep in mind that many of these components are likely to be empty for any particular URL. You may also use this to get the components of any URL by passing in a string or other variable in place of the field name.

Domain: {{ craft.vzUrl.parse(entry.fieldName).host }}

The following components are available:

• scheme e.g. http
• host e.g. www.google.com
• root e.g. http://www.google.com
• port
• user
• pass
• path e.g. /about
• query (without the question mark)
• fragment (without the hash)
• filetype e.g. pdf

Installation

Download and unzip the extension. Upload the vzurl folder to your /craft/plugins/ folder. Go to Settings -> Plugins in the Craft control panel and enable the VZ URL plugin.

That's it! Now you can use the URL fieldtype anywhere you were previously using a plain text field. Switching from a text field to a VZ URL field (or vice-versa) will not affect your data.

Support

Please post all bugs or feature requests in GitHub Issues. I maintain this fieldtype in my spare time, but I will try to respond to questions as quickly as possible.

Roadmap

• Cache validation results
• More output options
• Retrieve additional information about the webpage (OpenGraph, etc) and make it available in templates
