php - How to validate FormData object within Laravel 7 using AJAX post?

one text

Solution:

If I understand weel, you have one lead_id.
But your validator required an array of number.

(I've removed *. & .* from the line lead_id.)

Correction :

$validated = $request->validate([
            'lead_id' => 'numeric|required',
            '*.note.*' => 'string|required',
            //'files.*' => 'mimes:jpeg, jpg, png, bmp, doc, pdf, mp3, svg, gif, webp|nullable|max:250000',
        ]);

Can you change your AJAX call for :

(Added contentType: false,)

 $.ajax({
        url: "/leadme/create-note",
        method: "POST",
        cache:false,
        dataType: false,
        processData: false,
        contentType: false,
        data: formData,
        success: function(response) {
            console.log('Formdata sent');
            console.log(response);
            $(".toast").toast("show");
        },
        error: function (jqXHR, textStatus, errorThrown) {
            console.log(jqXHR, textStatus, errorThrown);
        }
    });
