Yii2:根据相关表中的另一个字段自动填充字段-php问题

Yii2: auto fill fields based on another field from related table(Yii2:根据相关表中的另一个字段自动填充字段)

本文介绍了Yii2:根据相关表中的另一个字段自动填充字段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个 MySQL 表和模型 patient_entry，其中包含字段 patient_name、city 和 state.我还有另一个表/模型 health_card，它也包含 patient_name、city 和 state.

I have a MySQL table and model patient_entry which contains fields patient_name, city and state. I also have another table/model health_card which also contains patient_name, city and state.

假设 patient_entry 表已经填充了 patient_name、city 和 state.

Suppose the patient_entry table is already filled with patient_name, city and state.

当我在 health_card 表单中输入数据时，当我通过与 patient_entry 表相关的下拉字段选择 patient_name 时，我想要要自动填充的相关 city 和 state 字段.

When I am entering data in health_card form, when I select the patient_name via drop-down field related to patient_entry table, I want the related city and state fields to be auto-filled.

我用于 health_card 的 _form.php 看起来像这样:

My _form.php for health_card looks like this:

    <head>
<script>

        $this->registerJs("$('#healthcard-patient_name').on('change',function(){
    $.ajax({
        url: '".yiihelpersUrl::toRoute("HealthCard/patient")."',
        dataType: 'json',
        method: 'GET',
        data: {id: $(this).val()},
        success: function (data, textStatus, jqXHR) {
            $('#healthcard-city').val(data.city);
            $('#healthcard-pincode').val(data.pin);
        },
        beforeSend: function (xhr) {
            alert('loading!');
        },
        error: function (jqXHR, textStatus, errorThrown) {
            console.log('An error occured!');
            alert('Error in ajax request');
        }
    });
});"); 

      </script>
</head>

并且在我添加的控制器中，根据建议，这个:

And in the controller I have added, as per the suggestion, this:

public function actionPatient($id){
    // you may need to check whether the entered ID is valid or not
    $model= appmodelsPatientEntry::findOne(['id'=>$id]);
    return yiihelpersJson::encode([
        'city'=>$model->disrict_city,
        'pin'=>$model->pin_code
    ]);
}

推荐答案

您所需要的只是调用 AJAX 请求来获取所需的字段.就像下面这样:

All you need is calling an AJAX request to get needed fields. Just act like below:

(我不知道你的型号名称)看看你的表格，看看你的 patient_name 字段的 id 是什么.它通常是 modelname-fieldname.我假设您的模型名称是 Patient.因此，patient_name 的 id 将是 patient-patient_name.

(I do not know your model name)take a look at your form and see what is the id of your patient_name field. It is usually modelname-fieldname. I assume that your model name is Patient. So, the id of patient_name would be patient-patient_name.

添加 ajax 请求(在您看来).

Add an ajax request (in your view).

调用 AJAX 的代码可能如下所示:

The code for calling AJAX could look just like below:

$this->registerJs("$('#patient-patient_name').on('change',function(){
    $.ajax({
        url: '".yiihelpersUrl::toRoute("controllerName/patient")."',
        dataType: 'json',
        method: 'GET',
        data: {id: $(this).val()},
        success: function (data, textStatus, jqXHR) {
            $('#patient-city').val(data.city);
            $('#patient-state').val(data.state);
        },
        beforeSend: function (xhr) {
            alert('loading!');
        },
        error: function (jqXHR, textStatus, errorThrown) {
            console.log('An error occured!');
            alert('Error in ajax request');
        }
    });
});");

注意事项:

使用您自己的代码更改上面代码中的ControllerName.
我假设 city 和 state 字段的 id 具有以下 id(s):patient-city 和 state-city 相对.
耐心是控制器中的一个动作
您可能需要删除警报|日志并对上述代码进行一些自定义
我没有考虑代码清理的任何条件.请确保用户数据正确.

Change the ControllerName in above code with your own.
I assumed that the id of city and state fields has the following id(s): patient-city and state-city relatively.
patient is an action in your controller
You may need to remove alerts|logs and do some customization on above code
I didn't consider any conditions for code cleaning. Please make sure that user data is correct.

最后，将操作代码添加到您的控制器中.

操作代码:

public function actionPatient($id){
    // you may need to check whether the entered ID is valid or not
    $model=  appmodelsPatient::findOne(['id'=>$id]);
    return yiihelpersJson::encode([
        'city'=>$model->city,
        'state'=>$model->state
    ]);
}
