[SOLVED] Can CHtml::link post form data?

Yii 1.1 General Discussion
1

Hi

I have this code in my view:




<?php echo CHtml::beginForm(); ?>

<?php echo CHtml::textField('items_saved',$data->items_saved); ?>


<b><?php echo CHtml::encode($data->getAttributeLabel('name')); ?>:</b>

<?php echo CHtml::link(CHtml::encode($data->name),array('showItemsSavedInGrid')); ?>

<br />


<?php echo CHtml::endForm(); ?>

Now what I want to do is to send [color="#000080"]$data->items_saved[/color] which is string like ‘1000004, 1000006, 1000009’.

So when user clicks name (CHtml:link which I am trying to do) it should call showItemsSavedInGrid() with ‘1000004, 1000006, 1000009’ which I use as [color="#FF0000"]IN[/color] parameter.

showItemsSavedInGrid() looks like:




public function showItemsSavedInGrid()

{   

    $items_saved=$_POST['items_saved'];

    $dataProvider=new CActiveDataProvider('AllItems',array(

    'criteria'=>array(

        // where id IN ('1000004, 1000006, 1000009')

    'condition'=>'id IN ('.$items_saved.'),

    ),

    ));

        //renders cGridView

    $this->render('list',array(

        'dataProvider'=>$dataProvider,

    ));

    }

And on new view I have rendered cGridView with my condition where id IN (‘1000004, 1000006, 1000009’).

Anyway it seems like $_POST[‘items_saved’] is not sent to controller. Because in application.log I have:




2010/11/22 21:14:22 [error] [system.db.CDbCommand] 

Error in querying SQL: 

SELECT COUNT(*) FROM `AllItems` `t` WHERE id IN ()

Can I send POST data by CHtml::link? Or maybe there is other way to send string like ‘1000004, 1000006, 1000009’ by CHtml::link to the controller.

Thanks for any suggestions.

try


<?php echo CHtml::link(CHtml::encode($data->name),array('showItemsSavedInGrid',array('items_saved'=>$data->items_saved))); ?>

and in controller access via


$_GET['items_saved']

Yeah that works as I expected

When I changed to $_GET, the URL in address bar is like:




http://yiiapp/index.php?r=..........&[items_saved]=1000004%2C1000006%2C1000009

Anyway I wanted to use $_POST not to have this IDs in URL. IS that possible?

If you wish to do that I recommend that you write your onclick javascript procedure to actually call a function that posts a dummy form.

It worked for me long time a go without knowing Yii… so what stops this technique to work with your approach now?

5

OK I’ll try that javascript thing.

You may use CHtml.linkButton to submit form on link is clicked.

7

Can I call any controller method using CHtml::linkButton ?




public static string linkButton(string $label='submit', array $htmlOptions=array ( ))

??

Yes you can:




echo CHtml::linkButton('Submit form', array('submit' => array('route')));

But you may also set this in form’s action directly.

I will create a button (not submit) or a link, that is up to you…

In your HTML create a dummy form:

<form id="dummy" action="" method="post">

<input type="hidden" name="variablenamehere" id="dummy-field"/>

</form>

Now, the important part is in your htmlOptions of the link or button or whatever you want that holds an onclick

‘rel’=>‘valuetopost’,

‘onclick’=>'javascript:

  &#036;(&quot;dummy-field&quot;).val(&#036;(this).attr(&quot;rel&quot;));


  &#036;(&quot;dummy-form&quot;).submit();return false;'

return false is if you do it from a dummy link (i.e. href="#") otherwise it will go to the top of the page. Now, with the same technique you could provide the with a class name, and also have the meta data to be posted in an attribute, then ON DOCUMENT READY, use jquery to update the dummy field and submit the form.




$('.classname').onclick(function(){ 


   var dummyField = $(this).attr("rel");


   $("dummy-field").val(dummyField);

   $("dummy-form").submit();return false;' 

});

Hi, I’ve been struggling with this all day, and what I found in this thread is technically what I need but can make it work ;(

I need to create a link with GET parameters the same way a form does.

I’ve written this:


<?php echo CHtml::link('test',array('yacht/index',array('SearchForm'=>array('area'=>'1','location'=>'src3')))); ?>

Similar to what rudenich suggested:


<?php echo CHtml::link(CHtml::encode($data->name),array('showItemsSavedInGrid',array('items_saved'=>$data->items_saved))); ?>

It creates the following URL: http://localhost:8888/www7/yacht/index?0[SearchForm][area]=1&0[SearchForm][location]=src3

but


$_GET['SearchForm']

has no value at all.

I don’t know why it adds ‘[’ and ‘]’ to SearchForm… when a form action generates a url it does it like this:

http://localhost:8888/www7/yacht/index?SearchForm[area]=1&SearchFor[location]=src3

Which works because


$_GET['SearchForm']

gets populated…

Any suggestion???

Thanks!

Two possible solutions:




<?php echo CHtml::link('test',array('yacht/index','SearchForm'=>array('area'=>'1','location'=>'src3'))); ?>







<?php echo CHtml::link('test', Yii::app()->createUrl('yacht/index',array('SearchForm'=>array('area'=>'1','location'=>'src3')))); ?>
