尝试在 bool 上读取属性“name”

如何解决尝试在 bool 上读取属性“name”

我在使用 Laravel 8 时遇到问题，我不确定如何识别错误。

发生以下情况..

在我的控制器中它看起来像这样：

$var  =  model::where('name',$name)->firstOrFail();
print_r($var)

Print_r 将这个返回给我

App\Models\test Object ( 
    [table:protected] => tb_test 
    [timestamps] => 
    [connection:protected] => MysqL 
    [primaryKey:protected] => id 
    [keyType:protected] => int 
    [incrementing] => 1 
    [with:protected] => Array ( ) 
    [withCount:protected] => Array ( ) 
    [perPage:protected] => 15 
    [exists] => 1 
    [wasRecentlyCreated] => 
    [attributes:protected] => Array ( 
            [id] => 48494980 
            [name] => TEST
    ) 
    [original:protected] => Array ( 
            [id] => 48494980 
            [name] => TEST 
    ) 
    [changes:protected] => Array ( ) 
    [casts:protected] => Array ( ) 
    [classCastCache:protected] => Array ( ) 
    [dates:protected] => Array ( ) 
    [dateFormat:protected] => 
    [appends:protected] => Array ( ) 
    [dispatchesEvents:protected] => Array ( ) 
    [observables:protected] => Array ( ) 
    [relations:protected] => Array ( ) 
    [touches:protected] => Array ( ) 
    [hidden:protected] => Array ( ) 
    [visible:protected] => Array ( ) 
    [fillable:protected] => Array ( ) 
    [guarded:protected] => Array ( [0] => * ) 
    ) 

当我尝试使用 foreach 时，它返回给我 Attempt to read property "name" on bool

谁能告诉我我做错了什么？

解决方法

如果您想一次遍历一个属性，请使用 toArray()

$var  =  model::where('name',$name)->firstOrFail();
$arrayVar = $var->toArray();

foreach( $arrayVar as $name => value) {
    //....
}
