Framework agnostic form helpers.

About

I've never found form libraries terribly useful. In my experience, they either work only for the most simple forms, or end up being way more difficult to use than just writing the HTML by hand.

That said, I do need some really basic form helpers to easily pre-populate form fields (like from previous POST to correct errors or from a database) and build drop down boxes.

The primary goal of this library is to solve those 2 problems in a way I don't hate. If I can make some more robust form helpers that don't get in my way while I'm at it, all the better.

This library provides helpers for setting default values in otherwise static html form elements as well as an input builder for dynamically creating form elements.

Quick Examples

You can view the full documentation with more examples at http://werx.moody.io/packages/forms/

Here's a few quick examples to get you started.

<?php
use werx\Forms\Form;

Form::setData($_POST);
?>

Text boxes

<input type="text" name="username" id="username" value="<?=Form::getValue('username')?>">
<?=Form::text('username')?>

Selects

<select name="state">
	<option value="AR" <?=Form::getSelected('state', 'AR')?>>Arkansas</option>
	<option value="TX" <?=Form::getSelected('state', 'TX')?>>Texas</option>
	<option value="OK" <?=Form::getSelected('state', 'OK')?>>Oklahoma</option>
</select>
<?=Form::select('state')->data(['TX' => 'Texas', 'AR' => 'Arkansas', 'OK' => 'Oklahoma'])->label('Choose')?>
<?=Form::select('color')->data(['Red', 'White', 'Blue'], true)->selected('White')?>

Checkboxes and Radios

<input type="checkbox" name="pets" value="Cat" <?=Form::getChecked('pets', 'Cat')?> /> Cat
<input type="checkbox" name="pets" value="Dog" <?=Form::getChecked('pets', 'Dog')?> /> Dog
<input type="checkbox" name="pets" value="Fish" <?=Form::getChecked('pets', 'Fish')?> /> Fish
<input type="radio" name="color" value="Red" <?=Form::getChecked('color', 'Red')?> /> Red
<input type="radio" name="color" value="Blue" <?=Form::getChecked('color', 'Blue')?> /> Blue
<input type="radio" name="color" value="Green" <?=Form::getChecked('color', 'Green')?> /> Green
<?=Form::checkbox('pets')->value('Cat')?> Cat
<?=Form::checkbox('pets')->value('Dog')->checked()?> Dog
<?=Form::checkbox('pets')->value('Fish')?> Fish
<?=Form::radio('color')->value('Red')?> Red
<?=Form::radio('color')->value('Blue')->checked()?> Blue
<?=Form::radio('color')->value('Green')?> Green

Use the checkedWhen() method if you want to check something pending some condition. Pass any condition you like. If it evaluates to true, it will call checked() on the element.

<?=Form::radio('color')->value('Red')->checkedWhen($some_value == 'Red')?> Red
<?=Form::radio('color')->value('Blue')->checkedWhen($some_value == 'Blue')?> Blue
<?=Form::radio('color')->value('Green')->checkedWhen($some_value == 'Green')?> Green

checkedWhen() works for both radios and checkboxes.

Installation

This package is installable and autoloadable via Composer as werx/forms. If you aren't familiar with the Composer Dependency Manager for PHP, you should read this first.

$ composer require werx/forms --prefer-dist

Unit Testing

$ vendor/bin/phpunit

Coding Standards

This library uses PHP_CodeSniffer to ensure coding standards are followed.

I have adopted the PHP FIG PSR-2 Coding Standard EXCEPT for the tabs vs spaces for indentation rule. PSR-2 says 4 spaces. I use tabs. No discussion.

To support indenting with tabs, I've defined a custom PSR-2 ruleset that extends the standard PSR-2 ruleset used by PHP_CodeSniffer. You can find this ruleset in the root of this project at PSR2Tabs.xml

Executing the codesniffer command from the root of this project to run the sniffer using these custom rules.

$ ./codesniffer
