Boring name for a boring package. Builds form HTML with a fluent-ish, hopefully intuitive syntax.
You can install this package via Composer by running this command in your terminal in the root of your project:
composer require avengers/formThis package works great as a replacement Form Builder that was removed in Laravel 5. The API is different but all of the features are there.
If you are using Laravel 4 or 5, you can register the FormServiceProvider to automatically gain access to the Old Input and Error Message functionality.
To do so, just update the providers array in your config/app.php:
'providers' => [
//...
'TheAvengers\Form\FormServiceProvider'
],You can also choose to use the Facade by adding an alias in config/app.php:
'aliases' => [
//...
'Form' => 'TheAvengers\Form\Facades\Form',
],Note that in Laravel 4, there is already a Form facade for the built-in Form Builder. If you want to use both, use a different alias. If you'd just like to use this one, remove the Form alias that points to the Illuminate component.

First, instantiate a FormBuilder...
$builder = new TheAvengers\Form\FormBuilder;Next, use the FormBuilder to build an element. For example:
// <input type="text" name="email" value="example@example.com" required="required">
<?= $builder->text('email')->value('example@example.com')->required(); ?>- All elements support method chaining, so you can add as many options to an element as you need.
- All elements implement
__toString()so there is no need to manually render.
// <form method="POST">
<?= $builder->open(); ?>
// <form method="GET">
<?= $builder->open()->get(); ?>
// <form method="POST">
// <input type="hidden" name="_method" value="PUT">
<?= $builder->open()->put(); ?>
// <form method="POST">
// <input type="hidden" name="_method" value="DELETE">
<?= $builder->open()->delete(); ?>
// <form method="POST" action="/test">
<?= $builder->open()->action('/test'); ?>
// <form method="POST" action="" enctype="multipart/form-data">
<?= $builder->open()->multipart() ?>
// <form method="POST" action="" enctype="custom">
<?= $builder->open()->encodingType("custom") ?>Text and password fields share the same interface.
// <input type="text" name="email">
<?= $builder->text('email'); ?>
// <input type="text" name="email" id="email_field">
<?= $builder->text('email')->id('email_field'); ?>
// <input type="password" name="password" class="required">
<?= $builder->password('password')->addClass('required'); ?>
// <input type="text" name="email" value="example@example.com" required="required">
<?= $builder->text('email')->value('example@example.com')->required(); ?>Other available methods:
placeholder($string)optional()defaultValue($string)disable()enable()
Textareas share the same interface as regular text fields, with a couple of extra useful methods.
// <textarea name="bio" rows="5" cols="50"></textarea>
<?= $builder->textarea('bio')->rows(5); ?>
// <textarea name="bio" rows="10" cols="20"></textarea>
<?= $builder->textarea('bio')->cols(20); ?>
// <textarea name="bio" rows="5" cols="20" class="important">My biography</textarea>
<?= $builder->textarea('bio')->rows(5)->cols(20)->addClass('important')->value('My biography'); ?>// <input type="checkbox" name="terms" value="1">
<?= $builder->checkbox('terms'); ?>
// <input type="checkbox" name="terms" value="1" checked="checked">
<?= $builder->checkbox('terms')->check(); ?>
// <input type="checkbox" name="terms" value="1">
<?= $builder->checkbox('terms')->uncheck(); ?>
// <input type="checkbox" name="terms" value="1" checked="checked">
<?= $builder->checkbox('terms')->defaultToChecked(); ?>
// <input type="checkbox" name="terms" value="agree">
<?= $builder->checkbox('terms')->value('agree'); ?>
// <input type="radio" name="color" value="red">
<?= $builder->radio('color', 'red'); ?>// <select name="birth_year"></select>
<?= $builder->select('birth_year'); ?>
// <select name="birth_year">
// <option value="0">1990</option>
// <option value="1">1991</option>
// <option value="2">1992</option>
// </select>
<?= $builder->select('birth_year', [1990, 1991, 1992]); ?>
// <select name="birth_year">
// <option value="1990">1990</option>
// <option value="1991">1991</option>
// <option value="1992">1992</option>
// </select>
<?= $builder->select('birth_year', ['1990' => 1990, '1991' => 1991, '1992' => 1992]); ?>
// <select name="birth_year">
// <optgroup label="Ontario">

// <option value="ottawa">Ottawa</option>
// </optgroup>
// <optgroup label="Quebec">

$options = [
'Ontario' => [
'toronto' => 'Toronto',
'ottawa' => 'Ottawa',
],
'Quebec' => [
'montreal' => 'Montreal',
'quebec_city' => 'Quebec City',

];
<?= $builder->select('birth_year', $options); ?>
// <select name="birth_year">

<?= $builder->button('Click Me'); ?>
// <button type="submit">Sign Up</button>
<?= $builder->submit('Sign Up'); ?>
// <button type="reset">Reset Form</button>
<?= $builder->reset('Reset Form'); ?>
// <button type="submit" class="js-submit">Sign Up</button>
<?= $builder->submit('Sign Up')->addClass('js-submit'); ?>Hidden Inputs
// <input type="hidden" name="secret" value="my-secret-value">
<?= $builder->hidden('secret')->value('my-secret-value'); ?>Basic Label
// <label>Email</label>
<?= $builder->label('Email'); ?>
// <label for="email">Email</label>
<?= $builder->label('Email')->forId('email'); ?>Wrapping another element
// <label>Email<input type="text" name="email"></label>
<?= $builder->label('Email')->before($emailElement); ?>
// <label><input type="text" name="email">Email</label>
<?= $builder->label('Email')->after($emailElement); ?>// Attributes can be set with attribute(...)
// <input type="text" name="foobar" min="4">
<?= $builder->text('foobar')->attribute('min', 4); ?>
// Or by calling the attribute name as a method
// <input type="text" name="foobar" min="4">
<?= $builder->text('foobar')->min(4); ?>
// Setting data-* attributes
// <input type="text" data-foo="bar" name="foobar">
<?= $builder->text('foobar')->data('foo', 'bar'); ?>
// Multiple data-* attributes can be set at once
// <input type="text" data-foo="bar" data-bar="foo" name="foobar">
<?= $builder->text('foobar')->data(['foo' => 'bar', 'bar' => 'foo']); ?>The FormBuilder can remember old input and prepopulate your form fields if you redirect back to the form because of a validation error.
To make this work, you must create a class that implements the OldInputInterface and pass it to the FormBuilder:
$builder->setOldInputProvider($myOldInputProvider);Now, your form elements will automatically populate with the user's old input data if it is available.
This works well with the defaultValue() methods, allowing you to set a default value that will be overridden by old input if the user has already submitted the form.
This package ships with a Laravel implementation out of the box, called
IlluminateOldInput.
FormBuilder also allows you to easily retrieve error messages for your form elements. To do so, just implement the ErrorStoreInterface and pass it to the FormBuilder:
$builder->setErrorStore($myErrorStore);This package ships with a Laravel implementation out of the box, called
IlluminateErrorStore.
// Check if the form has an error for an element
$builder->hasError('email');
// Retrieve the error message for an element
$builder->getError('email');You can also supply a format parameter to getError() to cleanup your markup. Instead of doing this:
<?php if ($builder->hasError('email')): ?>
<span class="error"><?= $builder->getError('email'); ?></span>
<?php endif; ?>...you can simply do this, which will display the formatted message if it exists, or nothing otherwise.
<?= $builder->getError('email', '<span class="error">:message</span'); ?>Assuming you set a CSRF token when instantiating the Formbuilder (or you are using Laravel), add a CSRF token to your form easily like so:
<?= $builder->token(); ?>Sometimes you might have a form where all of the fields match properties on some sort of object or array in your system, and you want the user to be able to edit that data. Data binding makes this really easy by allowing you to bind an object or array to your form that will be used to automatically provide all of the default values for your fields.
$model->first_name = "John";
$model->last_name = "Doe";
$model->email = "john@example.com";
$model->date_of_birth = new DateTime('1985-05-06');
<?= $builder->open(); ?>
<?= $builder->bind($model); ?>
<?= $builder->text('first_name'); ?>
<?= $builder->text('last_name'); ?>
<?= $builder->email('email'); ?>
<?= $builder->date('date_of_birth'); ?>
<?= $builder->close(); ?>This will work out of the box with Laravel's Eloquent models.
When using data binding, old input will still take priority over any of your bound values, so you can still easily redirect the user back to the form with any validation errors without losing any of the data they entered.
Note: Be sure to
bindbefore creating any other form elements.
