Question

我希望在使用ajax＆amp; amp;从数据库检索数据后更新表单中的某些字段。 JSON。

这是代码：

以我的形式：

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'anagrafica-form',
    // Please note: When you enable ajax validation, make sure the corresponding
    // controller action is handling ajax validation correctly.
    // There is a call to performAjaxValidation() commented in generated controller code.
    // See class documentation of CActiveForm for details on this.
    'enableAjaxValidation'=>false,
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>

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

    <div class="row">
        <?php echo $form->labelEx($model,'codicefiscale'); ?>
        <?php echo $form->textField($model,'codicefiscale',array('size'=>20,'maxlength'=>16)); ?>
        <?php echo $form->error($model,'codicefiscale'); ?>

                <div id="bottone_ricerca" style="display:inline;">
                <?php    
                    echo CHtml::ajaxButton( 'Ricerca',
                                            $this->createUrl('anagrafica/popolaAnagrafica'),
                                            array(
                                                'type' => 'POST',
                                                'datatype' => 'json',
                                                'data' => array('codfisc' => 'js:$(\'#AnagraficaForm_codicefiscale\').val()'),
                                                'success' => 'function(response){
                                                    $("#cand").html(response);
                                                    $("#'.CHTML::activeId($model,'cognome').'").val(response.cognome);
                                                    $("#'.CHTML::activeId($model,'nome').'").val(response.nome);
                                                    $("#'.CHTML::activeId($model,'email').'").val(response.email);




                                                   }'
                                                ), 
                                            array()
                          );
                ?>    

                </div>
                <div id="cand">

                </div>     

    </div>            

    <div class="row">

    <div class="row buttons">

在我的控制器中：

public function actionPopolaAnagrafica()
{
    $codfisc = Yii::app()->request->getParam('codfisc');
    echo $codfisc;
    if (Yii::app()->request->isAjaxRequest) {
        if ($codfisc == '') {
            echo CJSON::encode(array(
                'error' => 'true',
                'status' => 'Richiesta non valida.'
            ));
            Yii::app()->end();
        } else {   
            //$sql = "SELECT * FROM user WHERE username = ':codfisc'";
            $sql = "SELECT * FROM user WHERE username = '".$codfisc . "'";
            $cmd = Yii::app()->db->createCommand($sql);
            //$cmd->bindParam(":codfisc", $codfisc, PDO::PARAM_STR);
            $result = $cmd->queryRow();
            $sql2 = $cmd->text;                    
            if($result) {
                echo CJSON::encode(array(
                                        'error' => 'false',
                                        'status' => 'Codice Fiscale esistente',
                                        'username' => $result['username'],
                                        'cognome' => $result['cognome'],
                                        'nome' => $result['nome'],
                                        'email' => $result['email']
                                   )                                
                     );
                Yii::app()->end();
            } else {
                echo CJSON::encode(array(
                    'error' => 'true',
                    'status' => 'Il codice fiscale ' . $codfisc . ' non esiste. SQL = ' . $sql2 . '.'
                ));
                Yii::app()->end();
            }
        }

    }

我无法更新字段。答复是：

xxxyyyddxdd {“error”：“false”，“status”：“Codice Fiscale esistente”， “用户名”： “xxxyyyddxdd”， “cognome”： “Cognome”， “诺姆”： “诺姆”， “电子邮件”： “prova@email.it”}

但它应该是：

{“error”：“false”，“status”：“Codice Fiscale esistente”， “用户名”： “xxxyyyddxdd”， “cognome”： “Cognome”， “诺姆”： “诺姆”， “电子邮件”： “prova@email.it”}

我的错误在哪里？

由于

Answer 1

您需要删除以下行：

echo $codfisc;

（函数actionPopolaAnagrafica中的第二行）

Answer 2

public function actionPopolaAnagrafica()
{

    $codfisc = Yii::app()->request->getParam('codfisc');


      //this LINE!!!!!!!!!!!!!!!!!!!!!!!
    echo $codfisc;

Answer 3

更改：

'success' => 'function(response){
          $("#cand").html(response);
          $("#'.CHTML::activeId($model,'cognome').'").val(response.cognome);

有了这个：

'success' => 'function(response){
           $("#cand").html(response);

          var obj = jQuery.parseJSON( response );
          console.log(obj.cognome);
          $("#'.CHTML::activeId($model,'cognome').'").val(obj.cognome);

在输入HTML值之前解析JSON数据使用console.log（obj.cognome）;调试chrome中的值。

使用ajax和json更新表单上的字段
