i have insert form specific model , required fields validations works through rules function in model. want add field in form table , give required validation. how this?

consider following example

... class contact extends model {     public function rules()     {         return [             ['contact_name', 'string', 'required'],             // other attributes         ];     }     ...

users.php // model2 

... class users extends model {     public function rules()     {         return [             ['user_name', 'string', 'required'],             // other attributes         ];     }     ...

contactcontroller.php

... use \app\models\users; ... class contactcontroller extends controller {     public function actioncreate()     {         $contact_model = new contact;         $users_model = new users;         if($contact_model->load(yii::$app->request->post()) && $users_model->load(yii::$app->request->post()))         {             // saving code         }         else         {             return $this->render('create', ['contact_model'=>$contact_model, 'users_model'=>$users_model]);         }     }     ...

in views/contact/_form.php

... <?php $form = activeform::begin(); ?>          <?= $form->field($contact_model, 'contact_name')->textinput(['maxlength' => 255]) ?>          <?= $form->field($user_model, 'user_name')->textarea(['rows' => 6]) ?>          <!-- other inputs here -->          <?= html::submitbutton($contact_model->isnewrecord ? yii::t('app', 'create')              : yii::t('app', 'update'), ['class' => $contact_model->isnewrecord              ? 'btn btn-success' : 'btn btn-primary']) ?>          <?= html::a(yii::t('app', 'cancel'), ['article/index'], ['class' => 'btn btn-default']) ?>  <?php activeform::end(); ?> ...

here input 2 different models validated too, , make sure both input in same 1 form.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
