Laravel Livewire数据存储报错：Attempt to read property 'name' on array咨询

错误原因分析 #

• Livewire的$this->validate()方法返回的是关联数组，而非对象，你使用$validatedData->name这种对象属性访问语法，会导致对数组使用属性访问的错误。
• 定义$store数组时，元素结尾误用了分号;，这是PHP数组语法错误，元素间需用逗号,分隔。

修复后的Livewire代码 #

public $name;
public $email;
public $date_of_join;

public function submit() 
{
    $validatedData = $this->validate([
        'name'          => 'required',
        'email'         => 'required', 
        'date_of_join'  => 'required',        
    ]);       

    $store = [
        'name'          => ucwords(strtolower($validatedData['name'])),
        'email'         => $validatedData['email'], 
        'date_of_join'  => date("Y-m-d", strtotime($validatedData['date_of_join']))
    ];
    
    User::create($store);
}

额外优化建议 #

由于你已经在组件中声明了$name、$email、$date_of_join公共属性，验证通过后可以直接使用这些属性构建存储数组，代码更简洁：

public function submit() 
{
    $this->validate([
        'name'          => 'required',
        'email'         => 'required', 
        'date_of_join'  => 'required',        
    ]);       

    $store = [
        'name'          => ucwords(strtolower($this->name)),
        'email'         => $this->email, 
        'date_of_join'  => date("Y-m-d", strtotime($this->date_of_join))
    ];
    
    User::create($store);
}
