During the development process using the thinkphp framework, we often encounter situations that require data verification. thinkphp provides many convenient verification methods, but sometimes, we find that no matter how we call it, the data cannot be automatically verified. Why is this?

First of all, we need to understand how automatic verification is performed in thinkphp. When we define a validation rule in the model, it is as follows:

protected?$validate?=?[
????'name'??=>?'require|max:25',
????'age'???=>?'number|between:1,120',
????'email'?=>?'email',
];

This definition defines a validate attribute in the model. This attribute is an array that contains the rules that need to be verified. During use, we can call the $model->validate($data) method to verify the data. $dataThe parameter is the data that needs to be verified. If the verification passes, the method will return true, otherwise it will return an array of error messages.

However, in some cases, automatic verification is not performed when we call the validate() method. This is because thinkphp does not perform mandatory verification of data by default. If we want to verify the data, we need to manually call the verification method, as shown below:

//?強制進行自動驗證
$model->isUpdate(true)->validate($data);

Here, we set the isUpdate method to true, indicating that this is an update operation, This way we can force automatic verification.

In addition to manual calls, we can also override the $updateValidate attribute in the model to set forced validation, as shown below:

//?在模型中定義強制驗證
protected?$updateValidate?=?true;

In this way, during the update operation, Data verification will be performed automatically.

In summary, thinkphp does not perform mandatory verification on data by default. You need to manually call or set the mandatory verification attribute in the model. When using automatic verification, you need to pay attention to distinguish between new and update operations, because their verification rules may be different.
