People searching “Inertia reset form on success” clear the inputs on the click, then the request goes out empty. Reset after Laravel accepts the row.
TL;DR
- onSuccess can reset one field after a save.
- Resetting before the redirect drops the value you meant to send.
- Do not call
form.reset()in the submit handler beforeform.post. - Do not reset on
onError.
The fix#
The CRUD guide redirects to the list, which unmounts the form. You only need onSuccess when the user stays on the same page, such as a comment box under a post.
<script setup lang="ts">
import { useForm } from "@inertiajs/vue3";
const form = useForm({ body: "" });
function submit() {
form.post("/comments", {
preserveScroll: true,
onSuccess: () => form.reset("body"),
});
}
</script>onSuccess runs when the visit finishes without validation errors. form.reset("body") clears that key and its error. Other keys stay.
What to avoid#
Gotcha
Do not call form.reset() in the submit handler before form.post. The payload is already empty by the time Inertia reads it. Do not reset on onError. The user needs the text they just typed in order to fix it.
