📖 Examples

Basic Form Example

use leptos::*;
use leptos_forms_rs::*;

#[derive(Clone, Serialize, Deserialize, PartialEq, Debug)]
struct LoginForm {
    email: String,
    password: String,
    remember_me: bool,
}

impl Form for LoginForm {
    fn default_values() -> Self {
        LoginForm {
            email: "".to_string(),
            password: "".to_string(),
            remember_me: false,
        }
    }

    fn field_metadata() -> HashMap<String, FieldMetadata> {
        let mut metadata = HashMap::new();
        metadata.insert("email".to_string(), FieldMetadata {
            field_type: FieldType::Email,
            validators: vec![Validator::Required, Validator::Email],
            ..Default::default()
        });
        metadata.insert("password".to_string(), FieldMetadata {
            field_type: FieldType::Password,
            validators: vec![Validator::Required, Validator::MinLength(8)],
            ..Default::default()
        });
        metadata
    }

    fn form_name() -> &'static str { "LoginForm" }
    fn validate(&self) -> Result<(), ValidationErrors> { /* validation logic */ }
}

#[component]
pub fn LoginPage() -> impl IntoView {
    let (form, _submit_callback, _reset_callback) = use_form(LoginForm::default_values());

    view! {
        <div class="form">
            <FormField form=form.clone() name="email".to_string() />
            <FormField form=form.clone() name="password".to_string() />
            <FormSubmit form=form.clone() on_submit=|_| Ok(()) />
            <FormReset form=form.clone() />
        </div>
    }
}

Complex Multi-Step Form

use leptos_forms_rs::*;

#[component]
pub fn MultiStepForm() -> impl IntoView {
    let form = use_form::<MultiStepFormData>();
    let current_step = create_rw_signal(0);

    view! {
        <div class="multi-step-form">
            {move || match current_step.get() {
                0 => view! { <Step1 form=form.clone() /> },
                1 => view! { <Step2 form=form.clone() /> },
                2 => view! { <Step3 form=form.clone() /> },
                _ => view! { <Summary form=form.clone() /> }
            }}
        </div>
    }
}
