推荐答案
我想是因为您试图将输入值设置为数组.
I suppose it is because you try to set input value as array.
<select class="form-control select2" name="inspectiontype[]" id="inspectiontype" value="{{ Input::old('inspectiontype') }}" multiple="multiple" data-placeholder="Select Inspection Type" style="width: 100%;">
在这里尝试将array of ids设置为select的值，但是需要将selected属性添加到所选选项.
Here you try set array of ids as value of select, but you need to add selected attribute to selected option.
{{ Input::old('inspectiontype') }}
转换为
<?php echo htmlentities(array('id1', 'id2'), ENT_QUOTES, 'UTF-8', false)?>
我建议您使用 laravel集体形式，它将为您完成
I would recommend you to use laravel collective form it will do it for you
