Required_if laravel with multiple value
提问by Donny Akhmad Septa Utama
I have a dropdown menu like this:
我有一个这样的下拉菜单：
<select name="selection">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
</select>
<input type="text" name="stext">
I want the following in laravel:
我想在 laravel 中有以下内容：
public static myfunction(){
$input = \Input::only('selection','stext');
$rule = array(
'selection' => 'required',
'stext' => 'required_if:selection,2,3',
);
$validate = \Validator::make($input,$rule);
}
But if I select option 1, stextis still required. Why?
How can I fix it?
但是如果我选择选项1，stext仍然需要。为什么？我该如何解决？

You just have to pass all the values as parameters separated by comma:
您只需将所有值作为以逗号分隔的参数传递：
$rules = array(
'selection' => 'required',
'stext' => 'required_if:selection,2,3'
);

I think that the require_if validation accept only one value per time. Try to change your validation code as below:
我认为 require_if 验证每次只接受一个值。尝试更改您的验证代码如下：
$rule = array(
'selection' => 'required',
'stext' => 'required_if:selection,2|required_if:selection,3',
);
EDIT: Check LePhleg answer, is more cleaner. At the time of the answer that was not possible, just check the question, he was using the same method but not worked.
编辑：检查 LePhleg 的答案，更干净。在回答不可能的时候，只需检查问题，他正在使用相同的方法但没有奏效。

try this one
试试这个
if single match value then used like that
如果单个匹配值然后像那样使用
'stext' => 'required_if:selection,2'
if you have multiple value then used like that (separated by comma)
如果您有多个值，则像这样使用（用逗号分隔）
'stext' => 'required_if:selection,2,3'
for more information see documentation required_if

You can go ahead with sometimes validation for laravel. you can define a custom closure as in the below example
您有时可以继续验证 laravel。您可以定义一个自定义闭包，如下例所示
public static myfunction(){
$input = \Input::only('selection','stext');
$rule = array(
'selection' => 'required'
);
$validator->sometimes('stext', 'required', function($input){
return (($input->selection == 1) || ($input->selection == 2));
});
$validate = \Validator::make($input,$rule);
}
