I have a Form in Cakephp(version 2.4.4):
<?php echo $this->Form->create('Servicegroup');?>
I have to find a way to submit this form using a button, which contains a link. Besides I need to have all the request data from this form when I access the link. How could I implement this in the best way?
I am tryin with:
echo $this->Html->link($this->Form->button('calculateBudget', array('class' => 'btn btn_yellow', 'type' => 'submit')), array('controller' => 'orders', 'action' => 'calculateBudget'), array('class' => 'lbOn', 'escape' => false));
but this does not submit the form
I'm trying to make a simple search form (it will grow more complex soon so I'm using an ActiveForm here instead of simply passing GET parameters to the action method).
controller:
public function actionIndex()
{
$search_form = new UserSearchForm();
$search_form->load(Yii::$app->request->get(), $formName = '');
return $this->render('index', [
'search_form' => $search_form
]);
}
view:
<?php $form = ActiveForm::begin(['id' => 'search-form', 'method' => 'get']); ?>
<?= $form->field($search_form, 'q')->textInput(['name' => 'q']) ?>
<?= Html::submitButton('Search') ?>
<?php ActiveForm::end(); ?>
I'm using $formName = '' in controller and 'name' => 'q' in view to make the query string cleaner (simple q instead of UserSearchForm[q]).
Everything looks fine until first submit. I see a hidden q field in the form and after second submit the URL looks like /user?q=value1&q=value2, each submit adds another q to hidden fields. Is there a good way to get rid of those hidden fields? Or maybe the whole approach is wrong? I guess I'll need hidden fields there anyway (sorting, pagination etc).
You should simply set form action (if empty it will be the current url) :
<?php $form = ActiveForm::begin([
'id' => 'search-form',
'method' => 'get',
'action' => ['controller/index']
]); ?>
If you use for filtering the same action and controller as for displaying results, then
$form = ActiveForm::begin([
'id' => 'filter-form',
'method' => 'get',
'action' => Url::toRoute(\Yii::$app->request->getPathInfo())
]);
I'm currently using the following code to send an Ajax get request to my controller:
echo CHtml::ajaxLink('clickMe', array('ajax'), array('update'=>'#results'));
This works fine, the controller receives the request and updates the view accordingly.
Now, I want to send in this request attributes of the model, i.e. from model->getAttributes();
How should I do this? Create a JSON object of the attributes and send that with the request?
Just pass 'data' attribute and 'type' if needed:
echo CHtml::ajaxLink('clickMe', array('ajax'), array(
'update' => '#results'
'data' => CJSON::encode($model->attributes),
'type' => 'post',
));
This code just replaces #results contents with json. If you need something different, use 'success' instead of 'update' like this:
echo CHtml::ajaxLink('clickMe', array('ajax'), array(
'success' => 'function (response) {
// do everything you need
}',
'data' => CJSON::encode($model->attributes),
'type' => 'post',
));
Take a look at jquery ajax options for more information.
I have a gridview which contains a checkbox column and also uses pagination. When I check some checkboxes in the first page and navigate to the second page and check another one in the second page, the options I checked in the first page is not retained there. Is it posssible to retain the checkbox values during pagination?
Code for Gridview is
$widget = $this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $model->search(),
'cssFile' => Yii::app()->baseUrl . '/media/js/admin/css/admingridview.css',
//'filter' => $model,
'ajaxUpdate' => true,
'enablePagination' => true,
'columns' => array(
array(
'name' => 'id',
'header' => '#',
'value' => '$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
),
array(
'class' => 'CCheckBoxColumn',
'selectableRows' => '2',
'header' => 'Selected',
),
array(
'name' => 'fb_user_id',
'header' => 'FaceBook Id',
'value' => 'CHtml::encode($data->fb_user_id)',
),
array(
'name' => 'first_name',
'header' => 'Name',
'value' => 'CHtml::encode($data->first_name)',
),
array(
'name' => 'email_id',
'header' => 'Email',
'value' => 'CHtml::encode($data->email_id)',
),
array(
'name' => 'demo',
'type' => 'raw',
'header' => "Select",
'value' => 'CHtml::checkBox("email[]","",array("class"=>"check","value"=>$data->email_id))',
),
),
));
Edit:

You could use sessions/cookies to store the checked values. I'm not very sure how to make cookies work, so i'll tell you how to do it with sessions. Specifically the user session that yii creates.
Now to use sessions we need to pass the checked (and unchecked) ids to the controller, therefore we'll modify the data being sent to the controller on every ajax update(i.e between paginations), to do this we exploit the beforeAjaxUpdate option of CGridView.
I'm also using CCheckBoxColumn instead of the following in your code(of course you can modify the solution to suit your own needs):
array(
'name' => 'demo',
'type'=>'raw',
'header' => "Select",
'value' => 'CHtml::checkBox("email[]","",array("class"=>"check","value"=>$data->email_id))',
),
GridView Changes:
<?php $this->widget('zii.widgets.grid.CGridView', array(
// added id of grid-view for use with $.fn.yiiGridView.getChecked(containerID,columnID)
'id'=>'first-grid',
'dataProvider'=>$model->search(),
'cssFile' => Yii::app()->baseUrl . '/media/js/admin/css/admingridview.css',
// added this piece of code
'beforeAjaxUpdate'=>'function(id,options){options.data={checkedIds:$.fn.yiiGridView.getChecked("first-grid","someChecks").toString(),
uncheckedIds:getUncheckeds()};
return true;}',
'ajaxUpdate'=>true,
'enablePagination' => true,
'columns' => array(
array(
'name' => 'id',
'header' => '#',
'value' => '$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
),
array(
'name' => 'fb_user_id',
'header' => 'FaceBook Id',
'value' => 'CHtml::encode($data->fb_user_id)',
),
array(
'name' => 'first_name',
'header' => 'Name',
'value' => 'CHtml::encode($data->first_name)',
),
array(
'name' => 'email_id',
'header' => 'Email',
'value' => 'CHtml::encode($data->email_id)',
),
/* replaced the following with CCheckBoxColumn
array(
'name' => 'demo',
'type'=>'raw',
'header' => "Select",
'value' =>'CHtml::checkBox("email[]","",array("class"=>"check","value"=>$data->email_id))',
),
*/
array(
'class' => 'CCheckBoxColumn',
'selectableRows' => '2',
'header'=>'Selected',
'id'=>'someChecks', // need this id for use with $.fn.yiiGridView.getChecked(containerID,columnID)
'checked'=>'Yii::app()->user->getState($data->email_id)', // we are using the user session variable to store the checked row values, also considering here that email_ids are unique for your app, it would be best to use any field that is unique in the table
),
),
));
?>
Pay special attention to the code for beforeAjaxUpdate and CCheckBoxColumn, in beforeAjaxUpdate we are passing checkedIds as a csv string of all the ids(in this case email_ids) that have been checked and uncheckedIds as a csv string of all the unchecked ids, we get the unchecked boxes by calling a function getUncheckeds(), which follows shortly. Please take note here, that when i was testing i had used an integer id field (of my table) as the unique field, and not an email field.
The getUncheckeds() function can be registered like this anywhere in the view file for gridview:
Yii::app()->clientScript->registerScript('getUnchecked', "
function getUncheckeds(){
var unch = [];
/*corrected typo: $('[name^=someChec]') => $('[name^=someChecks]') */
$('[name^=someChecks]').not(':checked,[name$=all]').each(function(){unch.push($(this).val());});
return unch.toString();
}
"
);
In the above function pay attention to the selectors and each and push function.
With that done, we need to modify the controller/action for this view.
public function actionShowGrid(){
// some code already existing
// additional code follows
if(isset($_GET['checkedIds'])){
$chkArray=explode(",", $_GET['checkedIds']);
foreach ($chkArray as $arow){
Yii::app()->user->setState($arow,1);
}
}
if(isset($_GET['uncheckedIds'])){
$unchkArray=explode(",", $_GET['uncheckedIds']);
foreach ($unchkArray as $arownon){
Yii::app()->user->setState($arownon,0);
}
}
// rest of the code namely render()
}
That's it, it should work now.
For developing that scheme you would need to know working of what happens when you navigate.
When ever you navigate to a pagination page ajax calls are made and new data is received and it is fetched from CActive Record or what ever the data source. New data is in accordance of database records or source records. when you come back to previous page again Ajax call is made and content is updated so same comes as it is in database.
what i feel is you should save data of checked items temporary and make it permanent if action is made.
You can do something like this
<script type="text/javascript">
$("input:checkbox").click(function () {
var thisCheck = $(this);
if (thisCheck.is (':checked')){
// do what you want here, the way to access the text is using the
// $(this) selector. The following code would output pop up message with
// the selected checkbox text
$(this).val());
}
});
</script>
you can save temporary storage somewhere
Also make this work on normal form submit:
I wanted to add this as a comment on bool.dev's answer, but I do not have enough reputation to do that yet. So I had to put it in a separate answer.
bool.dev, your answer is great and it works well, thanx.
However, as intended, it only works when ajax calls update the gridview. I have the gridview forming part of a form, so I wanted it to also work on normal submission of the form, otherwise the checkboxes are not loaded again when there are other validation errors on the form.
So, in ADDITION to what you did, I added hidden fields on my form e.g.:
<input type="hidden" name='checkedBox1' id='checkedBox1' value=''>
<input type="hidden" name='uncheckedBox1' id='uncheckedBox1' value=''>
Then, before submitting the form, my sumbit button runs your getChecked() and getUncheckeds() functions and store their results in the hidden fields:
if ($('#checkedBox1').length >0) {$('[name=checkedBox1]').val(getChecked());}
if ($('#uncheckedBox1').length >0) {$('[name=uncheckedBox1]').val(getUncheckeds());}
In the controller, besides from checking for $_GET['checkedIds'], you also check for $_POST['checkedBox1'] and store its values to session in the same way you do for $_GET['checkedIds'], using the same session variable.
Do the same with $_POST['uncheckedBox1'].
That should work.
i am using the following code to publish to a Page's feed connection
$attachment = array('message' => 'xxxxxxxxxxxxxxxxx',
'name' => 'cccccccccccccccc',
'caption' => 'cccccccccccccccc',
'link' => 'http://apps.facebook.com/manydldotnet/',
'description' => "ccccccccccccc",
'picture' => "'cccccccccccccccc'",
'actions' => array(array('name' => 'Download!','link' => 'http://apps.facebook.com/manydldotnet/'))
);
$result = $facebook->api('/121468571287906/feed/','post',$attachment);
so the question is how to get the post_id after posting it?
The Post's id is stored in $result['id'].
It's the return value of the call to feed; this is also the case for /links, /photos, etc.
Ref: http://developers.facebook.com/docs/reference/php/facebook-api/
Check the value in the $result variable, that should be the actual post_id value.
