Yii2 Validation

Yii2 Validate value without model

Ad Hoc Validation

Yii2 email Validate without model

Sometimes you need to do ad hoc validation for values that are not bound to any model.

If you only need to perform one type of validation (e.g. validating email addresses), you may call the validate() method of the desired validator, like the following:

$email = 'test@example.com';$validator = new yii\validators\EmailValidator();

if ($validator->validate($email, $error)) {
    echo 'Email is valid.';
} else {
    echo $error;
}

PHP Code for email validation

Validating email addresses with filter_var()

<?php

$email_a = 'joe@example.com';
$email_b = 'bogus';

if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_a) email address is considered valid.";
}
if (filter_var($email_b, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_b) email address is considered valid.";
}

?>

Importing data from Excel Sheet

How to load Phpexcell in yii2

 "phpoffice/phpexcel": "dev-develop"

Put this code in composor.json and do a composer update.

open project folder in teminal and do composer update

First create a excell sheet same fields as import table.

Controller Action

public function actionImportexcel()
{

$inputFiles = 'uploads/branches.xlsx';

try{
$inputFileType = \PHPExcel_IOFactory::identify($inputFiles);
$objReader = \PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFiles);

} catch (Exception $ex) {
die('Error');
}

$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();

//$row is start 2 because first row assigned for heading.
for($row=2; $row<=$highestRow; ++$row)
{

$rowData = $sheet->rangeToArray('A'.$row.':'.$highestColumn.$row,NULL,TRUE,FALSE);

 //save to branch table.
$branch = new Branches;

$branch->branch_id = $rowData[0][0];
$branch->companies_company_id = $rowData[0][1];
.
.
.
$branch->save();

}
}

PHP knowledge for studying of Yii framework.

Two conditions in a for loop

$s = 1;

while ($result_row = mysql_fetch_assoc($query) && $s < 5)
{
echo $result_row['id'];
$s++;
}

break (PHP 4, PHP 5)

break ends execution of the current for, foreach, while, do-while or switch structure.

Examples:

for($i=0;$i<count($model);$i++)

{

echo $model[$i]['month_year'];

if($i<12) break;

}

$s=1
while ($result_row = mysql_fetch_assoc($query))
{
    echo $result_row['id'];
    $s++;
    if($s>5){
        break;
    }
}

DropDownList

Steps in Use DropDwonList

In controller

$model = new SomeModel();

$items=ArrayHelper::map(ModelName::find()->all(),'id','name');

return $this->render('view',['model'=>$model, 'items'=>$items])

Add in view

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($model, 'item_id')->dropDownList($items) ?>

<?php ActiveForm::end(); ?>

-----------------

Method of Add in DropDwonList in activeform

<?=

$form->field($model, 'permissions')->dropDownList($model->getPermissions(),

['prompt'=>'- Choose Your Permissions -'])

<?=

$form->field($model, 'company_status')->dropDownList([ 'ACTIVE' => 'ACTIVE', 'INACTIVE' => 'INACTIVE', ], ['prompt' => 'Status'])

<?=

$form->field($model, 'status')->dropDownList([ 'Active' => 'Active', 'Droped' => 'Droped', 'Completed' => 'Completed', ],['selected'=>true], ['prompt' => ''])

Click to view - Dependent Drop Down List Tutorials

Default Selection DropDownList Yii2

<?php

$model->palce_or_subcenter = Yii::$app->user->identity->subcenter; //default value set
echo $form->field($model, 'palce_or_subcenter')->dropDownList(
ArrayHelper::map(Groupitems::find()->andwhere(['category'=>6])->andwhere(['!=','id',0])->orderBy('description')->all(),'slid','description'),
['prompt'=>'Select One']
);
?>

Yii2 dropdownList select default option

<?= $form->field($model, 'ccid')->dropDownList(

getCenter(),['options' => [$ccid => ['Selected'=>'selected']]) ?>

'options'=>['72'=>['Selected'=>true]]

readonly dropdown

"disabled"=>"disabled" 
instead of "readonly"=>true

Set Dropdown list width in yii2

You can just add style in dropDownList show below code

'style' => 'width:90px !important'

<?= $form->field($model, 'experience_month')->dropDownList([ '0' => 0,'1'=>1,'2'=>2,'3'=>3,'4'=>4,'5'=>5 ,'6'=>6,'7'=>7,'8'=>8,'9'=>9,'10'=>10,'11'=>11],

['style' => 'width:90px !important', 'prompt' => 'Month'])->label('Year & Month') ?>

Yii2 Display DropDownList Values Using funtion

make a function in your model to return an array of your list

public function getOptions()
{
   return array(
      'EASY',
      'MEDIUM',
      'HARD',
   );
}

then you could use it like this

echo $form->dropdownList($model , 'category' , $model->options); // this will use that function to get the array

yii2:drop-down list for multiple values concat in one line

use this code concat multiple fields in single line.

ArrayHelper::map(\app\models\Medicine::find()->asArray()->all(),
    'id',
    function($model, $defaultValue) {
        return $model['medicine_name'].'-'.$model['medicine_id'];
    }
)

Example

<?= $form->field($modelSalesitem, "[{$i}]stockitem_id")
->dropDownList(
ArrayHelper::map(Stockcenter::find()->where(['center_ccid'=>1])->all(),
'stockitem_id' , function($model, $defaultValue) {
return $model['stockitem']['item_name'].' -'.$model['stock'].' - -'.$model['amount'];}),

['prompt'=>'Select Item']
)->label(FALSE); ?>
