La version 7.4 de symfony propose un nouveau compposant, le \u00ab\u00a0Multi-Step Forms\u00a0\u00bb.
\nPour configurer la navigation dans celui-ci vous devez cr\u00e9er une classe qui g\u00e8re le fonctionnement des bouton et l’indiquer sur votre formulaire principal<\/p>\n

$builder<\/span>-><\/span>add<\/span>(<\/span>'navigator'<\/span>,<\/span> MySecoursNavigatorType::<\/span>class<\/span>)<\/span>;<\/span><\/div><\/div>\n

Par d\u00e9faut le clic sur le bouton pr\u00e9c\u00e9dent, \u00e9crase les valeurs de l’\u00e9tape en cours, ce qui \u00e0 pour cons\u00e9quence que si vous \u00eates \u00e0 l’\u00e9tape 4 et que vous revenez \u00e0 l’\u00e9tape 1 en cliquant sur pr\u00e9c\u00e9dent \u00e0 multiple reprise, tous les donn\u00e9es des \u00e9tapes 2,3 et 4 seront effac\u00e9s. L’astuce est de modifier la configuration par d\u00e9faut du bouton pr\u00e9c\u00e9dent en passant \u00ab\u00a0‘clear_submission’ => false\u00a0\u00bb. Cela aura aussi pour effet de soumettre l’\u00e9tape courante, vous pouvez \u00e9ventuellement ajouter l’option \u00ab\u00a0‘validation_groups’ => false,\u00a0\u00bb si la validation de cette \u00e9tape ne vous int\u00e9resse pas lors du clic sur pr\u00e9c\u00e9dent, elle sera a nouveau faite par la suite lors du clic sur le bouton suivant.<\/p>\n
