Génération de formulaires dynamique, avec regénération sur la page action

Commenter

Contenu du snippet

Voila une classe pour générer des <form> et <input> proprement, sans attributs inexistants et récupérables sur la page action suivante !

J'ai commenté comme je pouvais dans la source :)

Exemple :

<?php
include 'generateForm.class.php';

$form = new generateForm('index2.php', 'myForm', 'post', array('title' => 'data', 'azd' => 'dddd'));
$form->addInput('texzdt', 'thom', array('golef' => 'afgepogh'), 40);
$form->addInput('texzdt', 'thom4', array('golef' => 'afgepogh'), 20);
$form->addInput('texafazfzdt', 'thom5', array('value' => 'afgezzzzzzzzzzzzzzzzzzzpogh'), 40);
$form->addInput('texzdt', 'thom6', array('golef' => 'afgepogh'), 50);
$form->addInput('texzdt', 'thom7', array('golef' => 'afgepogh'), 110);
$form->addInput('submit', 'thom2', array('value' => 'afgepogh'), 40);
$form->addInput('textarea', 'thom3', array('value' => 'afgepogh'), '5*10');

echo $form->showForm();
echo $form->showInput('thom');
echo '<br>';
echo $form->showInput('thom2');
echo '<br>';
echo $form->showInput('thom3');
echo '<br>';
echo $form->showInput('thom4');
echo '<br>';
echo $form->showInput('thom5');
echo '<br>';
echo $form->showInput('thom6');
echo '<br>';
echo $form->showInput('thom7');
echo $form->endForm();
?>

donc en gros, on genere dans la classe le form, les inputs, et apres on les affiche ou on veut :)

Sur la page suivante, si on a laissé $sendCatchValues à true :

<?php
include 'generateForm.class.php';
$form = new regenerateSameForm($_POST['regenerateForm']);
echo $form->showForm();
echo $form->showInput('thom');
echo '<br>';
echo $form->showInput('thom2');
echo '<br>';
echo $form->showInput('thom3');
echo '<br>';
echo $form->showInput('thom4');
echo '<br>';
echo $form->showInput('thom5');
echo '<br>';
echo $form->showInput('thom6');
echo '<br>';
echo $form->showInput('thom7');
echo $form->endForm();

?>

Ca refait le meme form :)

Voila je suis ouvert à toute amélioration ou continuation de ce projet :)

Conclusion :


Petite précision : l'attribut value dans textarea n'existe pas, mais il est possible de le mettre. Quand celui ci est mis dans l'array, le parametre value est supprimé, on garde la valeur du value et on le met entre lle <textarea> et le </texarea> ;)
