Form generation library with heavy use of closures for... everything.
Examples can be found in the tests directory along with a set of unit tests (coverage 99%+).
<?php
$form = new \ClosureForm\Form('signup-form', array('method'=>'post', 'action'=>'#', 'class'=>'form'));
/* username */
$form->addTextField('email')
->label('Email Address')
->validator(function($value){
//first validator
if(strlen($value) < 3){
return 'Email cannot be less than 3 characters';
}
})
->validator(function($value){
//second validator
if(!filter_var($value, FILTER_VALIDATE_EMAIL)){
return "This is not a valid email address";
}
});
/* password + confirmation */
$form->addPasswordField('password')->label('Password')->validator(function($value){
if(strlen($value) < 5){
return 'Password cannot be less than 5 characters';
}
});
$form->addPasswordField('confirm_password')->label('Confirm Password')->validator(function($value) use ($form) {
//example of using another field's value in a field validator via the USE keyword
if($value != $form->getField('password')->getSubmittedValue()){
return 'Password Confirmation did not match password';
}
});
/* submit */
$form->addButton('submit')->label('Submit')->action(function($form){
if($form->isValid()){
if(rand(1, 10) <= 5){
$form->addError('We have decided to randomly reject your registration. Sorry!');
return false;
} else {
return true;
}
}
});
$form->addButton('login')->label('or Login')->action(function($form){
//dont't validate - we don't care if the form is valid
header('Location:/some-login-page.php');
exit();
});
/* process form if submitted */
if($form->handleButtonActions())
{
echo 'Thank You, '.$form->getField('email')->getSubmittedValue();
}
/* output form */
echo $form->render();Outputs (without the tabs but including line breaks):
<form name="signup-form" method="post" action="#" class="form">
<input type="hidden" id="_internal_signup-form" name="_internal_signup-form" value="1"/>
<div class="form-row"><label for="email">Email Address</label><input type="text" id="email" name="email" /></div>
<div class="form-row"><label for="password">Password</label><input type="password" id="password" name="password" /></div>
<div class="form-row"><label for="confirm_password">Confirm Password</label><input type="password" id="confirm_password" name="confirm_password" /></div>
<div class="button-row">
<button name="submit" >Submit</button>
<button name="login" >or Login</button>
</div>
</form>
- CSRF Protection (not easy when most people use their own session handler). Session save handler could be passed as optional closure - otherwise native PHP session handling can be used.
- Radio Buttons
- Field Arrays (e.g. name[])
- Fieldsets
- Filters
- Automatic closure binding to form scope http://www.php.net/manual/en/closure.bind.php (5.4 only+) - 5.4 is still too rare in the wild to add this.
