Question

我想将表单中的多条记录添加到表格中。

我试图了解并遵循本指南并失败

http://www.yiiframework.com/doc/guide/1.1/en/form.table

我的代码无法保存。

我的控制器代码中有一条评论 A ，此处添加了isset()功能

这部分代码不会运行。

if(isset($_POST['MultiPart2'][$i]))

但是当我删除了isset（）函数时，我得到错误未定义的偏移量：0

这意味着此代码

$_POST['MultiPart2'][$i]

不工作。

我该怎么办？

这是我的帖子

的var_dump

$_POST['MultiPart2']

array(2) {
   ["[0"]=>
   array(3) {
     ["'name'"]=>
     string(3) "Vic"
     ["'age'"]=>
     string(2) "25"
     ["'sex'"]=>
     string(1) "m"
   }
  ["[1"]=>
  array(3) {
     ["'name'"]=>
     string(3) "Vic"
     ["'age'"]=>
     string(2) "25"
     ["'sex'"]=>
     string(1) "m"
   }
}

这是我的控制器代码

 public function actionCreate()
 {

    //insert multiple instances of model into array
    $model=array();
    for ($i=0; $i < 2; $i++) { 
        $model[]=new MultiPart2;
    }

    if(isset($_POST['MultiPart2']))
    {   
        foreach ($model as $i => $model) {

            if(isset($_POST['MultiPart2'][$i]))
             // A
            //with isset() the following code does not run
            {       

                $model->attributes=$_POST['MultiPart2'][$i];
                if($model->save())
                    echo "Saved";
            }
        }
    }
    $this->render('create',array(
        'model'=>$model,
    ));
}

这是我的观看代码

<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'multi-part2-form',
'enableAjaxValidation'=>false,
)); ?>

<?php echo $form->errorSummary($model); ?>
    <?php 
    foreach ($model as $i => $model) {
            ?>

                <div class="row">
                    <?php echo $form->labelEx($model,'name'); ?>
                    <?php echo $form->textField($model,"[$i][name]",array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                    <?php echo $form->error($model,'name'); ?>
                </div>

                <div class="row">
                    <?php echo $form->labelEx($model,'age'); ?>
                    <?php echo $form->textField($model,"[$i][age]",array('size'=>60,'maxlength'=>100, "value"=>"5")); ?>
                    <?php echo $form->error($model,'age'); ?>
                </div>

                <div class="row">
                    <?php echo $form->labelEx($model,'sex'); ?>
                    <?php echo $form->textField($model,"[$i][sex]",array('size'=>60,'maxlength'=>100, "value"=>"m")); ?>
                    <?php echo $form->error($model,'sex'); ?>
                </div> 
                <hr>
            <?php
        }

     ?>

<div class="row buttons">
    <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
</div>

<?php $this->endWidget(); ?>

以下是生成的HTML

<form id="multi-part2-form" action="/sam.com/system/index.php?r=multiPart2/create"      method="post">

Answer 1

将文本输入的生成更改为：

     <?php echo $form->textField($model,"[$i]name",array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                //...
     <?php echo $form->textField($model,"[$i]age",array('size'=>60,'maxlength'=>100, "value"=>"5")); ?>
                //..
     <?php echo $form->textField($model,"[$i]sex",array('size'=>60,'maxlength'=>100, "value"=>"m")); ?>

它在double qoutes "中的换行输入名称（现在$i并不解释为varialble - 因为它在sinqle qoutes中）。

也可以尝试更改：

 $model=array();
for ($i=0; $i < 2; $i++) { 
    $model[$i]=new MultiPart2;
}

if(isset($_POST['MultiPart2']))
{   

    foreach ($model as $i=>$mod) {

        if(isset($_POST['MultiPart2'][$i]))
         // A
        //with isset() the following code does not run
        {       

            $mod->attributes=$_POST['MultiPart2'][$i];
            if($mod->save())
                echo "Saved";
        }
    }
}

EDIT_2 _ 将查看代码更改为（名称相同的错误）：

    foreach ($model as $i => $mod) {
        ?>

            <div class="row">
                <?php echo $form->labelEx($mod,'name'); ?>
                <?php echo $form->activeTextField($mod,"[$i]name",array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                <?php echo $form->error($mod,'name'); ?>
            </div>
            //... other inputs

或尝试：

        foreach ($model as $i => $mod) {
        ?>

            <div class="row">
                <?php echo $form->labelEx($mod,'name'); ?>
                <?php echo $form->textField("MultiPart2[$id]['name']",$mod['name'],array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                <?php echo $form->error($mod,'name'); ?>
            </div>



            <div class="row">
                <?php echo $form->labelEx($mod,'age'); ?>
                <?php echo $form->textField("MultiPart2[$id]['age']",$mod['age'],array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                <?php echo $form->error($mod,'age'); ?>
            </div>


            <div class="row">
                <?php echo $form->labelEx($mod,'sex'); ?>
                <?php echo $form->textField("MultiPart2[$id]['sex']",$mod['sex'],array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>
                <?php echo $form->error($mod,'sex'); ?>
            </div>

Answer 2

您应该更改您的视图代码，如下所示：

删除''中名称周围的"[$i]['name']" - 以及所有字段

<?php echo $form->textField($model,"[$i][name]",array('size'=>60,'maxlength'=>100, "value"=>"Vic")); ?>

并且还改变了foreach中的变量名称，如Voodoo417所说。

foreach ($model as $i => $mod) {
