Makes Links Trait

The MakesLinks trait will allow you to access the parser with a linkify($text) method on your class.

Basic Usage

use TaylorNetwork\Linkify\MakesLinks;

class DummyClass
{
	use MakesLinks;
	
	protected $text = 'This has a link. https://google.com';
	
	public function getParsedText()
	{
		return $this->linkify($this->text);
	}
}

getParsedText() returns

'This has a link. [google.com](https://google.com)'

Override Config

use TaylorNetwork\Linkify\MakesLinks;
use TaylorNetwork\Linkify\Linkify;

class DummyClass
{
	use MakesLinks;
	
	protected $text = 'This has a link. https://google.com';
	
	public function getParsedText()
	{
		return $this->linkify($this->text);
	}
	
	public function linkifyConfig(&$linkify)
	{
		$linkify->setConfig('convertTo', Linkify::ConvertHTML);
		$linkify->setConfig('linkAttributes', [
			'class' => 'btn-link'
		]);
	}
}

getParsedText() returns

'This has a link. <a class="btn-link" href="https://google.com">google.com</a>'

With Custom Format

use TaylorNetwork\Linkify\MakesLinks;
use TaylorNetwork\Linkify\Linkify;

class DummyClass
{
	use MakesLinks;
	
	protected $text = 'This has a link. https://google.com';
	
	public function getParsedText()
	{
		return $this->linkify($this->text);
	}
	
	public function linkifyConfig(&$linkify)
	{
		$linkify->setConfig('convertTo', Linkify::ConvertCustom);
	}
	
	public function linkifyCustomParse(string $caption, string $url) 
	{
		return '=>' . $caption . '<=#' . $url . '#';
	}
}

getParsedText() returns

'This has a link. =>google.com<=#https://google.com#'

Config

Publish the config using the artisan command.

$ php artisan vendor:publish --provider="TaylorNetwork\Linkify\LinkifyServiceProvider"

Will publish the config file to config/linkify.php

---

Link Format

You can change the default link format by changing the convertTo setting in config/linkify.php

'convertTo' => Linkify::ConvertMarkdown, // Converts to markdown links
// OR
'convertTo' => Linkify::ConvertHTML,     // Converts to <a> links
// OR
'convertTo' => Linkify::ConvertCustom,   // Your own custom callback

---

Link Attributes (HTML Only)

You can add any HTML link attributes you want to include in the <a> tag when generating a link (Don't use href).

Add the key and value to the linkAttributes array.

'linkAttributes' => [
	'target' => '_blank',
	'class' => 'btn-link',
],

Would generate links:

<a target="_blank" class="btn-link" href="$url">$caption</a>

Where $caption and $url would be replaced automatically.

Note: attributes are added in the order from the array and this only runs if using the Linkify::ConvertHTML setting in convertTo

---

Only format non-formatted links

The checkForExistingFormatting setting should be set to true if you want to only convert links that don't have existing formatting (default).

For example:

// Link is already formatted, by user, or another package, etc.
$text = 'Link: [link](https://google.com)';

Linkify::instance()->parse($text);

// Returns

// If 'checkForExistingFormatting' is true
'Link: [link](https://google.com)'

// If 'checkForExistingFormatting' is false
'Link: [link]([google.com](https://google.com))'

---

Custom Formatting

You can define a custom formatter in the config file, but prefer that you use the MakeLinks trait.

See Makes Links Trait

'customCallback' => function ($caption, $url) {
	return '{' . $caption . '}#' . $url . '#';
},

If 'convertTo' => Linkify::ConvertCustom the $caption and $url will be passed to the callback.

This would return: '{google.com}#https://google.com#'
