问题描述
我有一个带有动态添加/删除输入的表单,但是,如果我添加输入但不输入任何内容,则将null值写入数据库,验证程序不会捕获null.Googling没有找到类似的问题,相反,每个人都对如何通过验证器传递null感兴趣.也许我对Google的搜索不满意.
I have a form with dynamically added / removed inputs, however if I add input and don't enter anything, the null value is written to the database, the validator does not catch null. Googling did not find a similar question, on the contrary, everyone was interested in how to pass null through the validator. Maybe I didn't google it well.
$request->validate([
'properties' => 'required|min:1',
]);
属性:
<div class="input-group row">
<label for="category_id" class="col-sm-2 col-form-label">Product properties: </label>
<div class="row">
<div class="col-lg-12">
<div id="inputFormRow">
<div class="input-group mb-3">
@isset($product)
@foreach($product->properties as $prod)
<input type="text" name="properties[][key]" value="{{ $prod['key'] ?? '' }}" class="form-control m-input editinp-key" placeholder="Key" autocomplete="off">
<input type="text" name="properties[][value]" value="{{ $prod['value'] ?? '' }}" class="form-control m-input ml-3 editinp-value" placeholder="Value" autocomplete="off">
<div class="input-group-append ml-3">
<button id="removeRow" type="button" class="btn btn-danger">Remove</button>
</div>
@endforeach
@endisset
@if(Session::has('properties'))
@foreach(Session::get('properties') as $prop)
<input type="text" name="properties[][key]" value="{{ $prop['key'] ?? '' }}" class="form-control m-input" placeholder="Key" autocomplete="off">
<input type="text" name="properties[][value]" value="{{ $prop['value'] ?? '' }}" class="form-control m-input ml-3" placeholder="Value" autocomplete="off">
<div class="input-group-append ml-3">
<button id="removeRow" type="button" class="btn btn-danger">Remove</button>
</div>
@endforeach
@endif
</div>
</div>
<div id="newRow"></div>
<button id="addRow" type="button" class="btn btn-info">Add</button>
</div>
</div>
</div>
jQuery:
$("#addRow").click(function () {
var html = '';
html += '<div id="inputFormRow">';
html += '<div class="input-group mb-3">';
html += '<input type="text" name="properties[][key]" class="form-control m-input ml-3" placeholder="Key" autocomplete="off">';
html += '<input type="text" name="properties[][value]" class="form-control m-input ml-3" placeholder="Value" autocomplete="off">';
html += '<div class="input-group-append ml-3">';
html += '<button id="removeRow" type="button" class="btn btn-danger">Remove</button>';
html += '</div>';
html += '</div>';
$('#newRow').append(html);
});
// remove row
$('#removeRow').on('click', function () {
$(this).closest('#inputFormRow').remove();
});
推荐答案
假设您使用 key
和 value
键传递对象数组,则可以像这个:
Assuming you pass an array of objects with key
and value
keys, you can validate your request like this:
$request->validate([
'properties' => 'required|min:1',
'properties.*.key' => 'required',
'properties.*.value' => 'required',
]);
