How do I validate an array of integers in Laravel
提问by Kola
I have an array of integer like this $someVar = array(1,2,3,4,5). I need to validate $someVarto make sure every element is numeric.How can I do that?
我有一个像这样的整数数组 $someVar = array(1,2,3,4,5)。我需要验证$someVar以确保每个元素都是数字。我该怎么做？
I know that for the case of a single valued variable, the validation rule would be something like this $rules = array('someVar'=>'required|numeric'). How can I apply the same rule to every element of the array $someVar?
我知道对于单值变量的情况，验证规则将是这样的$rules = array('someVar'=>'required|numeric')。如何将相同的规则应用于数组的每个元素$someVar？
Thanks a lot for helping.
非常感谢您的帮助。

Now laravel has option to set condition on array elements. No need to write your own validator for simple things like validation int array. Use this (if using in controller)-
现在 laravel 可以选择在数组元素上设置条件。无需为验证 int 数组等简单事物编写自己的验证器。使用这个（如果在控制器中使用）-
$validator = \Validator::make(compact('someVar'), [
'someVar' => 'required|array',
'someVar.*' => 'integer'
]);
$this->validateWith($validator);
or
或者
$this->validate($request, [
'someVar' => 'array',
'someVar.*' => 'int'
]);

Validator::extend('numericarray', function($attribute, $value, $parameters)
{
foreach($value as $v) {
if(!is_int($v)) return false;
}
return true;
});
Use it
用它
$rules = array('someVar'=>'required|array|numericarray')
Edit:Up to date version of this validation would not require the definition of numericarraymethod.
编辑：此验证的最新版本不需要numericarray方法的定义。
$rules = [
'someVar' => 'required|array',
'someVar.*' => 'integer',
];

In Laravel 5 you can check the elements in an array by using .*. For you this would mean:
在 Laravel 5 中，您可以使用.*. 对你来说，这意味着：
$rules = array('someVar' => 'required|array',
'someVar.*' => 'integer')

Start with adding a new validation attribute
从添加新的验证属性开始
Validator::extend('numeric_array', function($attribute, $values, $parameters)
{
if(! is_array($values)) {
return false;
}
foreach($values as $v) {
if(! is_numeric($v)) {
return false;
}
}
return true;
});
The function will return false if attribute is not an array or if one value is not a numeric value. Then add message to `app/lang/en/validation.php'
如果属性不是数组或某个值不是数值，则该函数将返回 false。然后将消息添加到`app/lang/en/validation.php'
"numeric_array" => "The :attribute field should be an array of numeric values",

You can add custom rules for integer type value check of array
您可以为数组的整数类型值检查添加自定义规则
Just open file
直接打开文件
/resources/lang/en/validation.php
Add the custom message before "accepted" message in the file.
在文件中的“已接受”消息之前添加自定义消息。
'numericarray' => 'The :attribute must be numeric array value.',
"accepted" => "The :attribute must be accepted.",
Now Open the file
现在打开文件
/app/Providers/AppServiceProvider.php
and then add the custom validation in boot function.
然后在引导功能中添加自定义验证。
public function boot()
{
$this->app['validator']->extend('numericarray', function ($attribute, $value, $parameters)
{
foreach ($value as $v) {
if (!is_int($v)) {
return false;
}
}
return true;
});
}
Now you can use the numericarray for integer type value check of array
现在您可以使用 numericarray 进行数组的整数类型值检查
$this->validate($request, [
'field_name1' => 'required',
'field_name2' => 'numericarray'
]);

AppServiceProvider.php
应用服务提供者.php
Validator::extend('integer_array', function($attribute, $value, $parameters)
{
return Assert::isIntegerArray($value);
});
Assert.php
断言.php
/**
* Checks wheter value is integer array or not
* @param $value
* @return bool
*/
public static function isIntegerArray($value){
if(!is_array($value)){
return false;
}
foreach($value as $element){
if(!is_int($element)){
return false;
}
}
return true;
}

There is only the 'array' validation which ensures that the value is an array, but for your specific case you will have to create a custom filter:
只有“数组”验证可确保该值是一个数组，但对于您的特定情况，您必须创建一个自定义过滤器：
