Question

我修改我的部门网站允许用户输入作者和排名。

但是当我在排名文本中键入非整数时，它无法显示任何验证错误消息。

array('dataset_id, author_id, rank', 'numerical', 'integerOnly'=>true),

 <?php echo $form->error($model,'rank'); ?>

当我添加

时也在控制器文件中

    if ($author['rank'] == $rank && $author['name'] == $name) {
                        $model->addError("warning", "Duplicate input");

在视图文件中也无法显示任何东西，只需刷新页面空白文本字段

<?php echo $form->errorSummary($model); ?>

这是DatasetAuthor模型规则

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('dataset_id ,rank,author_name', 'required'),
        array('dataset_id, author_id, rank', 'numerical', 'integerOnly'=>true),
                    // The following rule is used by search().
        // Please remove those attributes that should not be searched.
        array('id, dataset_id, author_id, doi_search, author_name_search , orcid_search , rank_search', 'safe', 'on'=>'search'),
    );
}

控制器功能

 public function actionCreate1() {
    $model = new DatasetAuthor;

    // Uncomment the following line if AJAX validation is needed
    // $this->performAjaxValidation($model);
    //this is fake information
    $model->dataset_id = 1;
    //update 
    if (!isset($_SESSION['authors']))
        $_SESSION['authors'] = array();

    $authors = $_SESSION['authors'];

    if (isset($_POST['DatasetAuthor'])) {



        $ranks = trim($_POST['DatasetAuthor']['rank']);
        $names = trim($_POST['DatasetAuthor']['author_name']);
        if (substr($names, -1) == ";")
            $names = substr($names, 0, -1);
        $valid = true;
        $namearray = array();
        if ($names != "")
            $namearray = explode(";", $names);
    //            var_dump($namearray);
        if ($ranks == "")
            $rankarray = array();
        else
            $rankarray = explode(";", $ranks);
    //            var_dump($rankarray);
    //            if (count($namearray) != count($rankarray)) {
    //                $model->addError("error", "the number of name and rank are different!");
    //                $valid = false;
    //            }
        //test names
        if ($valid) {

                if (!is_numeric($rank)) {

Answer 1

CModel::addError()的第一个参数必须是类属性的名称。在您的情况下，name和/或rank都可以。

if ($author['rank'] == $rank && $author['name'] == $name) {
    $model->addError("rank", "Duplicate input");

<强>更新

从控制器代码中，您没有将表单数据传递到模型中。这就是字段为空的原因。另外，您不会调用实际检查$model->save()的{{1}}或$model->validate()。调用这些将不再需要您在控制器中添加的大多数有效性检查。

rules()
