Simple, elegant WordPress-like Shortcodes the Laravel way.
The package has been developed and tested to work with the latest supported versions of PHP and Laravel as well as the following minimum requirements:
- Laravel 11
- PHP 8.2
| Laravel | PHP | Branch |
|---|---|---|
| 11+ | 8.2+ | master |
| 10 and below | 8.1 and below | 1.x |
Install the package via Composer.
composer require tehwave/laravel-shortcodesLaravel Shortcodes work much like WordPress' Shortcode API.
<?php
use tehwave\Shortcodes\Shortcode;
$compiledContent = Shortcode::compile('[uppercase]Laravel Shortcodes[/uppercase]');
// LARAVEL SHORTCODESRun the following command to place a fresh Shortcode class in your new app/Shortcodes directory.
php artisan make:shortcode ItalicizeTextEach Shortcode class contains a handle method, that you may use to output into the compiling content.
Within the handle method, you may access the attributes and body properties.
Note
All values in the attributes array are cast to string type when parsed unless specifically cast to a type via the $casts property.
<?php
namespace App\Shortcodes;
use tehwave\Shortcodes\Shortcode;
class ItalicizeText extends Shortcode
{
/**
* The code to run when the Shortcode is being compiled.
*
* You may return a string from here, that will then
* be inserted into the content being compiled.
*
* @return string|null
*/
public function handle(): ?string
{
if (isset($this->attributes['escape_html']) && $this->attributes['escape_html'] === 'true')) {
return sprintf('<i>%s</i>', htmlspecialchars($this->body));
}
return sprintf('<i>%s</i>', $this->body);
}
}The shortcode's tag is derived from the class name to snake_case.
You may specify a custom tag using the tag property or by overwriting the getTag method.
Shortcode tags must be alpha-numeric characters and may include underscores.
<?php
namespace App\Shortcodes;
use tehwave\Shortcodes\Shortcode;
class ItalicizeText extends Shortcode
{
/**
* The tag to match in content.
*
* @var string
*/
protected $tag = 'italics';
}Run a string through the compiler to parse all shortcodes.
<?php
use tehwave\Shortcodes\Shortcode;
$compiledContent = Shortcode::compile('[italics escape_html="true"]<b>Hello World</b>[/italics]');
// <i><b>Hello World</b></i>You may specify a list of instantiated Shortcode classes to limit what shortcodes are parsed.
<?php
use tehwave\Shortcodes\Shortcode;
$shortcodes = collect([
new ItalicizeText,
]);
$compiledContent = Shortcode::compile('[uppercase]Hello World[/uppercase]', $shortcodes);
// [uppercase]Hello World[/uppercase]Laravel Shortcodes supports casting attributes to various data types. This can be useful when you need to ensure that the attributes passed to your shortcodes are of a specific type.
booleanintegerfloatstringarraycollectionobjectjsonencryptedhasheddate(casts toCarbon\Carboninstance)
To use casts, you need to create a shortcode class and specify the casts in the $casts property.
<?php
namespace App\Shortcodes;
use tehwave\Shortcodes\Shortcode;
use Carbon\Carbon;
class ExampleShortcode extends Shortcode
{
/**
* The attributes that should be cast.
*
* @var array
*/
protected $casts = [
'is_active' => 'boolean',
'count' => 'integer',
'price' => 'float',
'name' => 'string',
'tags' => 'array',
'options' => 'collection',
'metadata' => 'object',
'config' => 'json',
'published_at' => 'date',
];
/**
* The code to run when the Shortcode is being compiled.
*
* @return string|null
*/
public function handle(): ?string
{
$publishedAt = $this->attributes['published_at'] instanceof Carbon
? $this->attributes['published_at']->toFormattedDateString()
: 'N/A';
$tags = implode(', ', $this->attributes['tags']);
$options = $this->attributes['options']->implode(', ');
return sprintf(
'Active: %s, Count: %d, Price: %.2f, Name: %s, Published At: %s, Tags: %s, Options: %s',
$this->attributes['is_active'] === true ? 'Yes' : 'No',
$this->attributes['count'],
$this->attributes['price'],
$this->attributes['name'],
$publishedAt,
$tags,
$options
);
}
}When you compile content with this shortcode, the attributes will be automatically cast to the specified types.
<?php
use tehwave\Shortcodes\Shortcode;
$compiledContent = Shortcode::compile('[example is_active="1" count="10" price="99.99" name="Sample" published_at="2023-06-29" tags=\'["tag1","tag2","tag3"]\' options=\'["option1","option2"]\']');
// Active: Yes, Count: 10, Price: 99.99, Name: Sample, Published At: Jun 29, 2023, Tags: tag1, tag2, tag3, Options: option1, option2You can retrieve the attributes as direct properties of the shortcode instance.
<?php
namespace App\Shortcodes;
use tehwave\Shortcodes\Shortcode;
class ExampleShortcode extends Shortcode
{
protected $casts = [
'is_active' => 'boolean',
'count' => 'integer',
];
public function handle(): ?string
{
// Access attributes as properties
$isActive = $this->is_active;
$count = $this->count;
return sprintf('Active: %s, Count: %d', $isActive === true ? 'Yes' : 'No', $count);
}
}I developed Laravel Shortcodes for use with user provided content on gm48.net.
The content is parsed using a Markdown converter called Parsedown, and because users can't be trusted, the content has to be escaped.
Unfortunately, this escapes the attribute syntax with double quotes, but singular quotes can still be used as well as just omitting any quotes.
Note
Quotes are required for any attribute values that contain whitespace.
Let's take a look at the following content with some basic Row, Columnand Image shortcodes.
# Controls:
[row]
[column]
[image align=left src=http://i.imgur.com/6CNoFYx.png alt='Move player character']
[/column]
[column]
[image align=center src=http://i.imgur.com/8nwaVo0.png alt=Jump]
[/column]
[column]
[image align=right src=http://i.imgur.com/QsbkkuZ.png alt='Go down through platforms']
[/column]
[/row]
When running the content through the following code:
$parsedDescription = (new Parsedown())
->setSafeMode(true)
->setUrlsLinked(false)
->text($this->description);
$compiledDescription = Shortcode::compile($parsedDescription);We can expect to see the following output:
<h1>Controls:</h1>
<p></p>
<div class="container-fluid">
<div class="row">
<div class="col">
<img src="http://i.imgur.com/6CNoFYx.png" class="mr-auto" alt="Move player character">
</div>
<div class="col">
<img src="http://i.imgur.com/8nwaVo0.png" class="mx-auto" alt="Jump">
</div>
<div class="col">
<img src="http://i.imgur.com/QsbkkuZ.png" class="ml-auto" alt="Go down through platforms">
</div>
</div>
</div>You should still escape any user input within your shortcodes' handle.
