Yii表格输入

Question

I want to add multiple records from a form into a table.

I have tried to understand and follow this guide and failed

Yii tabular input

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

My code does not save.

I have a comment in my controller code written A, here with the isset() function added

this part of the code will not run.

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

But when I removed the isset() function I get the error Undefined offset: 0

This means this code

$_POST['MultiPart2'][$i]

Is not working.

What should I do?

Here is the var_dump of my post

$_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"
   }
}

Here is my controller code

 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,
    ));
}

And here is my view code

<?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(); ?>

Here is the generated HTML

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

Answer 1

You should change your view code as below:

Remove '' around name in "[$i]['name']" - and in all fields also

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

And also change the variable name in foreach as Voodoo417 said.

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