html

 <div class="box__material-field field">
                    <label class="box__label box__label--material label">Listez les matériels nécessaires pour ce projet</label>
                    <div class="box__box-input box__box-input--material control">
                        <span>&#x25CF;</span>

                </div>
                @error('material')
                <p class="help is-danger">{{ $message }}</p>
                @enderror

controller

  $t =  $request->validate([
            
                'material'              => 'required|array|min:1',
                'material.*'            => 'distinct|nullable|string',
                'material.0'            => 'required|string|min:3',
               
            ]);

my ajaxjquery


   var project_material = [];
        $('input[name^=material]').each(function () {
            // console.log($(this).val());
            project_material.push($(this).val());
        });

 project_material.forEach(material => {
     
            formData.append('material', material);

I find solution:

I did that

    var materials = $('input[name*=material]');

        for (var i = 0; i < materials.length; i++) {
            formData.append(materials[i].name, materials[i].value);
        }

instead of that

   var project_material = [];
        $('input[name^=material]').each(function () {
            // console.log($(this).val());
            project_material.push($(this).val());
        });

 project_material.forEach(material => {
     
            formData.append('material', material);

        });
