I have dropDownList in my view ( data from db) :
use yii\widgets\ActiveForm;
\app\assets\HelloAsset::register($this);
$form = ActiveForm::begin();
$users=\app\models\User::find()->all();
$items=\yii\helpers\ArrayHelper::map($users,'id','username');
echo $form->field($model, 'username')->dropDownList($items);
echo \yii\bootstrap\Html::submitButton('Send');
ActiveForm::end();
I want to get data from 'username' in my controller:
$model=new Data();
if ($model->load(\Yii::$app->request->post())){
echo 'it is status:'.$model->username;
}else {
return $this->render('simple', ['model' => $model]);
}
But data is null.
How I must get data in right?
Please, help me solve this problem.

Fairly new to codeigniter and i just cant find the right way to load an array into a view.
for example lets say i have an array like
$data = [
'title' => 'my title,
'desc' => 'my desc,
];
i can pass that to my view like
return view('myview',$data);
then simply echo it out in my view like
<h1><?= $title ?></h1>
<p><?= $desc ?></p>
That works fine. but now lets say i have another array like :
$moredata =[
'more_data' => 'some more data',
'even_more_data' => 'even more data',
];
if i try to add that to my data array like
$data[] = $moredata
when i try to access 'more_data' or 'even_more_data' in my view like
<?= $more_data ?>
i get a undefined variable error for $moredata. So how do i access the variables within that new array? am i declaring them properly?
also if i wanted to loop through the secondary array how do i do that. trying
<?php foreach($moredata as $items){ ?>
<li><?php echo $items; ?></li>
<?php } ?>
also gives me an undefined variable error for $moredata
any help on how to do this correctly in codeigniter 4 appreciated.
Codeigniter uses the key of the array you're giving him to create variables name.
You should init it this way :
$moredata =[
'more_data' => 'some more data',
'even_more_data' => 'even more data',
];
// key of your array will be a variable name in your view
$data['my_var_name_in_view'] = $moredata
return view('myview',$data);
Then in your view you will be able to perform this :
<?php foreach($my_var_name_in_view as $items){ ?>
<li><?php echo $items; ?></li>
<?php } ?>
Yii2 Dependant drop down not working when we open update page.My depend drop down value came from database. When I create entry It works Very well with the condition. but I when go for Update then Pre selectect value does not show. i.e. Which I save while creating. This is my _form.php
$arrCountry = \yii\helpers\ArrayHelper::map($modelCountry, 'country_id', 'country');
echo $form->field($model, 'country_id')->dropDownList($arrCountry,
['prompt'=>'-Choose a country-',
'onchange'=>'
$.post( "'.Yii::$app->urlManager->createUrl('country/lists?id=').'"+$(this).val(), function( data ) {
$( "select#city_name" ).html( data );
});
']);
$dataPost=\yii\helpers\ArrayHelper::map(City::find()->asArray()->all(), 'city_id', 'city_name');
// print_r($dataPost);die;
echo $form->field($model, 'city_id')
->dropDownList(
$dataPost,
['id'=>'city_name']
);
2.Controller
public function actionLists($id)
{
$countCity =City::find()
->where(['city_id' => $id,'status'=>'not assign'])
->count();
$arrCity = City::find()
->where(['city_id' => $id,'status'=>'not assign'])
->orderBy('city_id DESC')
->all();
if($countCity>0){
foreach($arrCity as $arrCity){
echo "<option value='".$arrCity->city_id."'>".$arrCity->city_name."</option>";
}
}
else{
echo "<option>-</option>";
}
}
Depending on this question: Yii2 updating two related models does not show data of the second. I have manged calling the related model InvoiceItems to the Invoices model it hasMany relation.
However, updating leads to insert new records in invoice_items table instead of updating the current related records to the invoices table.
I tried to add the id field of each InvoiceItems record in the _form view to solve this issue, but it still exist.
The following is actionUpdate of the InvoicesController:
public function actionUpdate($id)
{
$model = $this->findModel($id);
//$invoiceItems = new InvoiceItems();
$count = count(Yii::$app->request->post('InvoiceItems', []));
//Send at least one model to the form
$invoiceItems = [new InvoiceItems()];
//Create an array of the products submitted
for($i = 1; $i < $count; $i++) {
$invoiceItems[] = new InvoiceItems();
}
if ($model->load(Yii::$app->request->post()) && $model->save()) {
//$invoiceItems->invoice_id = $model->id;
if (Model::loadMultiple($invoiceItems, Yii::$app->request->post())){
foreach ($invoiceItems as $item){
$item->invoice_id = $model->id;
//$item->id = $model->invoiceItems->id;
$item->save(false);
}
return $this->redirect(['view', 'id' => $model->id]);
}
else{
return var_dump($invoiceItems);
}
} else {
//$invoiceItems->invoice_id = $model->id;
$invoiceItems = $this->findInvoiceItemsModel($model->id);
return $this->render('update', [
'model' => $model,
'invoiceItems' => $invoiceItems,
]);
}
}
This is the code of _form view of InvoicesController:
<div class="invoices-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'created')->textInput() ?>
<?= $form->field($model, 'type')->textInput(['maxlength' => true]) ?>
<hr />
<?php if (is_array($invoiceItems)): ?>
<?php foreach ($invoiceItems as $i => $item): ?>
<?= $form->field($item, "[$i]id")->textInput();?>
<?= $form->field($item, "[$i]item_id")->textInput();?>
<?= $form->field($item, "[$i]unit_id")->textInput();?>
<?= $form->field($item, "[$i]qty")->textInput();?>
<?php endforeach; ?>
<?php else: ?>
<?= $form->field($invoiceItems, "item_id")->textInput();?>
<?= $form->field($invoiceItems, "unit_id")->textInput();?>
<?= $form->field($invoiceItems, "qty")->textInput();?>
<?php endif; ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') : Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
The following screen shot, visually, demonstrates what I have got:
if you in update you don't need new record you should remove
this part
$count = count(Yii::$app->request->post('InvoiceItems', []));
//Send at least one model to the form
$invoiceItems = [new InvoiceItems()];
//Create an array of the products submitted
for($i = 1; $i < $count; $i++) {
$invoiceItems[] = new InvoiceItems();
}
The $invoiceItems you create in this way are obviuosly "new" and then are inserted ..for an update the model must to be not new..
You have already the related models to save they came from post.. and from load multiple
If you however need to manage new model (eg: because you added new record in wide form update operation) you can test
$yourModel->isNewRecord
and if this is new check then if the user have setted properly the related fields you can save it with
$yourModel->save();
otherwise you can simple discart.. (not saving it)
I am pretty sure that this code below of course fills a array named $invoiceItems with the submitted data.
if (Model::loadMultiple($invoiceItems, Yii::$app->request->post())){
foreach ($invoiceItems as $item){
$item->invoice_id = $model->id;
//$item->id = $model->invoiceItems->id;
$item->save(false);
}
}
But all $items have the scenario "insert" (could be that you allow the setting of the attribute 'ID' but normally this isn't allowed in the Gii generated code. and then you get "new items" whenever you save.
if you add a return var_dump($invoiceItems);after the loadMultiple you will see that only the safe attributes are filled with the submitted data.
You are also not validating them before saving, which is also kind of bad.
if (Model::loadMultiple($invoiceItems, Yii::$app->request->post()) && Model::validateMultiple($invoiceItems)) {
http://www.yiiframework.com/doc-2.0/guide-input-tabular-input.html
According to scaisEdge answer and this widget documentation. I could able to determine the problem solution.
Simply, in my code I neglected the relation between the two models, when I say:
$count = count(Yii::$app->request->post('InvoiceItems', []));
//Send at least one model to the form
$invoiceItems = [new InvoiceItems()];
The value of $invoiceItems should be obtained using the relation like the following:
$invoiceItems = $model->invoiceItems;
However, I still have another issue with adding new records to the related model InvoiceItems during the update.
I am using dependant dropdownlist for get value for subject dropdown when select value from 'Grade' dropdown. It is working fine. But the problem is when there are only one value in grade dropdown the subject dropdown is not updated.
this is my code:-
Grade DropDown----------
($data is consist of grade)
<?php echo CHtml::dropDownList('myDropDown1','',$data,array(
'id'=>'gr',
'empty' => '(Select Grade)',
'style'=>'width:200px',
'ajax' =>
array(
'type'=>'POST', //request type
'url'=>CController::createUrl('sub'), //action to call
'update'=>'#cls', // which HTML element to update
)
)); ?>
Subject Dropdown (which depend on grade dropdown)------------
<?php echo CHtml::label('Subject',''); ?>
<?php echo CHtml::dropDownList('myDropDown3','',array(),array(
'id'=>'sub',
'prompt'=> 'Please select a class', 'style'=>'width:150px',
'style'=>'width:200px',
)); ?>
<?php //echo $form->error($model,'sub_id'); ?>
In controller-------------------
public function actionClass()
{
$grd = $_POST['myDropDown1'];
$c_id = TbClass::model()->findAll('id=:id',
array(':id'=>$grd,));
$data3 = CHtml::listData($c_id,'id','grade');
$grd2 = array_shift($data3);
$sub1 = TbClass::model()->findAll('grade=:grade',
array(
':grade'=>$grd2,
));
$data4 = CHtml::listData($sub1,'id','class');
foreach($data4 as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
}
This code is working fine. Problem is when grade has only one value in the dropdown , cannot update the subject dropdown.
I think your problem is in array_shift,
have you checked the value of $grd2 ?
I have a form that submits data to a database in a CodeIgniter app (CI v. 2.0.2). We are allowing users to "edit" records by having them resubmit a record with new values and then doing an update. On submit, the form calls the vote controller's create method. Inside the create method, we check to see if there's already a record based on an entry code and the user's ID. If there is, we update; otherwise we create a new record. The creation works just fine; it's only the update I'm having an issue with. Here's the code.
view
<div id="vote_form">
<?php
$hidden = array('dot_judge_id' => $this->session->userdata('dot_judge_id'));
echo form_open('vote/create');
$entry_code_data = array(
'name' => 'entry_code',
'id' => 'entry_code',
'value' => set_value('entry_code')
);
echo form_hidden($hidden);
$score_options = array('1'=>'1 (lowest)', '2'=>'2','3'=>'3', '4'=>'4','5'=>'5 (highest)');
?>
<p><label for="entry_code">Entry code: </label><?php echo form_input($entry_code_data); ?></p>
<p><label for="q1">Question 1: </label><?php echo form_dropdown('q1', $score_options, ''); ?></p>
<p><label for="q2">Question 2: </label><?php echo form_dropdown('q2', $score_options, ''); ?></p>
<p><label for="q3">Question 3: </label><?php echo form_dropdown('q3', $score_options, ''); ?></p>
<p><label for="q4">Question 4: </label><?php echo form_dropdown('q4', $score_options, ''); ?></p>
<p><label for="q5">Question 5: </label><?php echo form_dropdown('q5', $score_options, ''); ?></p>
<p><?php echo form_submit('submit', 'Submit vote'); ?></p>
<?php echo form_close(); ?>
<?php echo validation_errors(); ?>
</div>
controller
function create() {
$id = $this->input->post('entry_code');
$judge_id = $this->input->post('dot_judge_id');
$data = array(
'entry_code' => $id,
'dot_judge_id' => $judge_id,
'q1' => $this->input->post('q1'),
'q2' => $this->input->post('q2'),
'q3' => $this->input->post('q3'),
'q4' => $this->input->post('q4'),
'q5' => $this->input->post('q5'),
);
//first check to see if there's already a record for this judge/entry
//if so, update. Otherwise, insert
$vote_id = $this->vote_model->getEntryById($id, $judge_id);
if($vote_id) {
log_message('debug', 'vote id exists: '.$vote_id);
$this->vote_model->updateRecord($data, $vote_id);
}
else {
log_message('debug', 'vote id does not exist; creating new');
$this->vote_model->createRecord($data);
}
/*
after submission, go to another page that gives choices - review entries, submit another entry, log out
*/
$data['msg'] = "Entry submitted";
$this->menu();
}
model
function getEntryByID($id, $judge_id) {
//determine if record already exists for entry/judge
$sql = 'SELECT vote_id from dot_vote WHERE entry_code = ? AND dot_judge_id = ?';
$query = $this->db->query($sql, array($id, $judge_id));
if($query->num_rows() == 1) {
$row = $query->row();
return $row->vote_id;
}
else {
return false;
}
}
function createRecord($data) {
$this->db->insert('dot_vote', $data);
return;
}
function updateRecord($data, $vote_id) {
log_message('debug', 'vote id is passed: '.$vote_id);
$this->db->where('vote_id', $vote_id);
$this->update('dot_vote', $data);
}
I know it's making it into the updateRecord method because the log_message output is in my log file displaying the correct vote_id (the auto-increment field of the returned record). But what I get in the browser is the following:
Can anyone point me in the right direction here? I have error display on in my config file, and have gotten SQL errors when they occur, so I don't think this is a SQL error. But I have no idea what could be happening in that tiny little function that's causing this. My next step is to skip the active record update and just use a standard query, but I'd like to know what's causing the problem here, even if I can get it to work the other way.
This line stood out:
$this->update('dot_vote', $data);
Do you mean this?
$this->db->update('dot_vote', $data);
