我通过javascript从我的表单发送了一个数组,它从不同的输入字段中获取值,然后将其存储在单个变量中。
<input type="hidden" name="details" id="details">
JS
document.querySelectorAll('form')[1].addEventListener('submit', function(event) {
var details = [];
for (var i = 0; i < {{ $event->grocery->items()->count() }}; i++) {
details[i] = [
document.querySelectorAll('.store')[i].value,
document.querySelectorAll('.item')[i].value,
document.querySelectorAll('.quantity')[i].value,
document.querySelectorAll('.brand')[i].value,
document.querySelectorAll('.size')[i].value,
];
}
document.querySelector('#details').value = JSON.stringify(details);
});
然后在我的控制器中,我使用json_decode
$request->details = json_decode($request->details);
现在,我想验证每次迭代(只是为了检查它是否为空)。所以,我喜欢这个,
$request->validate([
...
'details.*.*' => 'required'
]);
但我的问题是这没有做任何事情。即使我发送了一个空迭代,它也会继续而不会返回错误。
我在这里做错了吗?请帮帮我。

var转储详细信息示例
array:3 [▼
0 => array:5 [▼
0 => "Grocery"
1 => "Grocery"
2 => "Grocery"
3 => "Grocery"
4 => "Grocery"
]
1 => array:5 [▼
0 => "Grocery"
1 => "Grocery"
2 => "Grocery"
3 => "Grocery"
4 => "Grocery"
]
2 => array:5 [▼
0 => "Grocery"
1 => "Grocery"
2 => "Grocery"
3 => "Grocery"
4 => "Grocery"
]
]

如果您将数组值命名为
,将会更容易document.querySelectorAll('form')[1].addEventListener('submit', function(event) {
var details = [];
for (var i = 0; i < {{ $event->grocery->items()->count() }}; i++) {
details[i] = {
store: document.querySelectorAll('.store')[i].value,
item: document.querySelectorAll('.item')[i].value,
quantity: document.querySelectorAll('.quantity')[i].value,
brand:document.querySelectorAll('.brand')[i].value,
size: document.querySelectorAll('.size')[i].value,
};
}
document.querySelector('#details').value = JSON.stringify(details);
});
验证将如下所示:
$request->validate([
...
'details.*.store' => 'required',
'details.*.item' => 'required',
'details.*.quantity' => 'required',
'details.*.brand' => 'required',
'details.*.size' => 'required'
]);
但如果它不适合你,总会有Laravel的Custom Validation Rules
修改强>:
我想可能问题在于您的数据更新:
$request->details = json_decode($request->details);
相反,您应该modify your input befor validation和Modify input before form request validation
$request->request->set('details', json_decode($request->details));
