$infoModel = InfoModel::findOne(1);
The above is to find the data with id 1. I have printed $infoModel, which is an object.
However, the correct data can be printed successfully by outputting the following two sentences:
echo $infoModel -> name; //这个可以理解 他是对象可以->
echo $infoModel['name']; //这个不理解 他不是数组啊
The following is the printed $infoModel:
app\models\InfoModel Object
(
[_attributes:yii\db\BaseActiveRecord:private] => Array
(
[id] => 1
[name] => 我问问2
[age] => 32
)
[_oldAttributes:yii\db\BaseActiveRecord:private] => Array
(
[id] => 1
[name] => 我问问2
[age] => 32
)
[_related:yii\db\BaseActiveRecord:private] => Array
(
)
[_errors:yii\base\Model:private] =>
[_validators:yii\base\Model:private] =>
[_scenario:yii\base\Model:private] => default
[_events:yii\base\Component:private] => Array
(
)
[_behaviors:yii\base\Component:private] => Array
(
)
)
Also, by the way<?php echo $form -> field($infoModel,'name')->textInput(array('value' => $infoModel['name'])); ?>
Is the first parameter $infoModel of the field here necessarily a model object? I tried to convert $infoModel into an array in the controller and an error occurred? ? ?

AR can be accessed in array mode because it implements the interface ArrayAccess
. If you want to extract the data content, you can use the model’s getAttributes
method
