Hi!
I want to create a front-end form with dynamic text fields based on pages titles.
For the moment I merge the form.fields in the twig template with my custom hashes of data.
TWIG
{% extends "forms/default/form.html.twig" %}
{% set fieldset = {
type: "fieldset",
legend: "Sélectionnez vos quantités par article",
fields: {}
} %}
{% for item in page.find('/home/_catalogue').collection %}
{% set itemfield_name = item.slug %}
{% set itemfield_options = {} %}
{% for i in range(0, item.header.qty) %}
{% set itemfield_options = itemfield_options|merge([i]) %}
{% endfor %}
{% set itemfield_value = {
label: item.header.label ? item.header.label : item.title,
type: "select",
options: itemfield_options
} %}
{% set fieldset_newfields = array_key_value(
itemfield_name,
itemfield_value,
fieldset.fields
) %}
{% set fieldset = fieldset | merge({"fields": fieldset_newfields}) %}
{% endfor %}
{% set formfields = array_key_value("articles", fieldset, form.fields) %}
{% set form = form | merge({"fields": formfields}) %}
My visitor see the correct form.
But when I submit I get an error : "Argument 1 passed to Grav\Common\Data\Data::merge() must be of the type array, string given, called in /var/www/grav/development/user/sites/shop.amatiq.fr/plugi..."
How to make it ok?
May I try another method?
Thanks!
