Getting Form Data Using Ajax

Yii 1.1 General Discussion
1

I am trying to get the data from this form into the relevant controller using Ajax, but it displays the Error message Undefined Index, Player

<?php

&#036;form=&#036;this-&gt;beginWidget('CActiveForm', array(


	'id'=&gt;'player-form',


	'enableAjaxValidation'=&gt;false,


));

?>

<div class="row">

&lt;?php echo CHtml::activeLabelEx(&#036;model,'item'); ?&gt;


&lt;?php echo &#036;form-&gt;textField(&#036;model,'item') ?&gt;

</div>

<div class="row">

&lt;?php echo CHtml::activeLabelEx(&#036;model,'currentQty'); ?&gt;


&lt;?php echo &#036;form-&gt;textField(&#036;model,'currentQty') ?&gt;

</div>

<div class="row">

&lt;?php echo CHtml::activeLabelEx(&#036;model,'requiredQty'); ?&gt;


&lt;?php echo &#036;form-&gt;textField(&#036;model,'requiredQty')  ?&gt;

</div>

<div class="row">

&lt;?php echo CHtml::activeLabelEx(&#036;model,'notes'); ?&gt;


&lt;?php echo &#036;form-&gt;textField(&#036;model,'notes')  ?&gt;

</div>

<div class="row">

&lt;?php echo CHtml::ajaxButton(&quot;Insert Item&quot;, array('player/ajaxcreate','type'=&gt;'POST'),array('success'=&gt;'allFine')); ?&gt;

</div>

Filename of the above form is list.php

public function actionAjaxCreate() {

$p = new Player();

$p->attributes=$_POST[‘Player’];

if($p->save()){

echo &quot;OK&quot;; // echo or not, if an exception dont occur then is OK.

}else{

throw new Exception(&quot;Sorry, cant create a player&quot;,500);

}

Any ideas on what is wrong here

2

do a var dump of your POST array and check what keys you getting in your controller

3

Sorry if its a bit silly but how do you see the results of var dump in yii

4

you can use php’s dump method, Yii is php

5

I did that but it doesnt display any results

&#036;var=&#036;_POST['Player'];


    echo var_dump(&#036;var);


   var_dump(&#036;var);
6

do a dump on the entire array, try this


echo "<tt><pre>";

var_dump($_POST);

exit;

Dear Friend

Kindly check the following

change the ajaxButton to ajaxSubmitButton.




<?php echo CHtml::ajaxButton("Insert Item",array('player/ajaxcreate','type'=>'POST'),array('success'=>'allFine')); ?>

to




<?php echo CHtml::ajaxSubmitButton("Insert Item", array('player/ajaxCreate'),array('success'=>'function(data){console.log(data)}')); ?>

Regards.

Dear Friend

Let us have the controller logic like this.




public function actionAjaxCreate() 

{

    $p = new Player();

    if(isset($_POST["Player"]) && Yii::app()->request->getIsAjaxRequest())

    {

         $p->attributes=$_POST['Player'];

         if($p->save()){

             echo "You have succesfully save data";

             Yii::app()->end();

          }

         else{

             echo "Something went wrong:try again";

             Yii::app()->end();

    }

}

Then in the form…




<?php echo CHtml::ajaxSubmitButton("Insert Item", array('player/ajaxCreate'),array('success'=>'function(data){alert(data)}')); ?>
