i have a laravel blade template and i need to extends a layous with different values depending on parameter status.
I've tried the follow solution but it does not work.
It seems that always to be considered the first #extends but $patient is null so I expect the second #extends statement to be considered.
Is the following statement correct?
#if(isset($patient->id))
#extends('layouts.app', [
'class' => '',
'elementActive' => 'patients'
])
#else
#extends('layouts.app', [
'class' => '',
'elementActive' => 'diets'
])
#endif
Do you have some suggestions?
Thank you.
Solved with:
#extends('layouts.app', [
'class' => '',
'elementActive' => $patient ? 'patients': 'diets']
)

I am implementing page cache for one of my page. For depenedency, I have to check an array, which can be either exist or not. Possible array keys cane ,
usersearch['id'], usersearch['name'], usersearch['phone]. I have to add dependency for any change in these values as well.
Also, I have to clear cache for any update or add in user table.
Is there any possible solution for this.?
Thanks in advance
You can use variations
public function behaviors(){
$usersearch = Yii::$app->requst->get('usersearch');
return [
[
'class' => 'yii\filters\PageCache',
'only' => ['index'],
'duration' => 60,
'variations' => [
'YOUR_DYNAMIC_VALUE1','YOUR_DYNAMIC_VALUE2'
],
'dependency' => [
'class' => 'yii\caching\DbDependency',
'sql' => 'SELECT COUNT(*) FROM post',
],
],
];
}
Ref link
IN YOUR CASE ,you can use
'variations' => \Yii::$app->requst->get('usersearch')??[],
or
'variations' => [
\/Yii::$app->requst->get('usersearch')['id'] ?? '',
\Yii::$app->requst->get('usersearch')['name'] ?? '',
\Yii::$app->requst->get('usersearch')['phone'] ?? '',
]
You could use a yii\caching\FileCache component with the following configuration.
Firstly, you set the cache in the init function of your controller:
Yii::$app->setComponents([
'yourCacheName' => [
'class' => \yii\caching\FileCache::class,
'defaultDuration' => 1800, //cache duration in seconds
'keyPrefix' => Yii::$app->getSession()->getId(). '_'
]
]);
Here, the parameter keyPrefix is set so that it is linked to the session ID. Thus, the visitors do not see each other's cached page. If the content is static and equal, regardless of the user or the session, this parameter can be removed.
In the view that must be cached you can call the beginCache function and the dependency as follows:
$this->beginCache('cache-id', [
'cache' => Yii::$app->yourCacheName, // the name of the component as set before
'variations' => [
$usersearch['id'] ?? '',
$usersearch['name'] ?? '',
$usersearch['phone'] ?? '',
],
'dependency' => [
'class' => \yii\caching\DbDependency::class,
'sql' => 'SELECT count(*) FROM your_user_table'
]
]);
// your view
$this->endCache();
I have Yii2 application which uses the Kartik plugin to initialize Select2 dropdowns in forms.
I have one particular Select2 which uses AJAX call to get the data for the drop down options.
<?=
$form->field($model, 'court_house_id', ['enableAjaxValidation' => true, 'selectors' => ['input' => '#' . $id . "-court-house"],'template' => FormHelper::GenerateFieldTemplate([6])])
->widget(Select2::classname(), [
'options' => ['id' => $id . "-court-house", 'placeholder' => Yii::t('app', 'Search court house...')],
'hashVarLoadPosition' => \yii\web\View::POS_READY,
'pluginOptions' => [
'dropdownParent' => new JsExpression("$('#$modalWindowId')"),
'allowClear' => true,
'minimumInputLength' => 2,
'language' => [
'errorLoading' => new JsExpression("function () { return '" . Yii::t('app', 'Search...') . "'; }"),
],
'ajax' => [
'url' => app\components\UrlMaker::link('data/court-house-list'),
'dataType' => 'json',
'data' => new JsExpression('function(params) { return {q:params.term}; }')
],
'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
'templateResult' => new JsExpression('function(courthouse) { return courthouse.text; }'),
'templateSelection' => new JsExpression('function (courthouse) { return courthouse.text;}'),
]])
->label(Yii::t('app', 'Court House'), ['class' => FormHelper::GenerateLabelClassTemplate([3])]);
?>
Intentionally pasting all of the code, although most of it is irrelevant I would assume.
I have this loaded in multiple dynamically created forms thus all the strange ids and selectors. However, the form has different dropdown which controls whether some of the fields are shown (and required) or not. This particular field above is only shown in one of the scenarios which all the other variations of the form do not have it. So the model has the following validation:
[['court_house_id', 'staff'], 'required', 'on' => self::SCENARIO_ONE],
By the way staff is just a regular text field and everything works for it.
In order to change the scenario, I have the following line in the view with the form:
<?php $model->scenario = \app\models\MyModel::SCENARIO_ONE; ?>
The problem is that when I submit the form empty, the staff field gets marked in red as invalid but the court house is marked in green as valid although it is empty.
If I go into the model and remove the 'on' => self::SCENARIO_ONE part then everything works as expected - on empty submit the court house field also lights up in red but that would be a problem for the rest of my scenarios where this field is not needed.
Any ideas what might be causing the problem and how to resolve it?
Try to set the scenario in controller before calling save() method, for example
$model = new MyModel(['scenario' => MyModel::SCENARIO_ONE])
Using this link.
I tried to add a where clause in addField where the dropdown should load the contents as options only if they match a condition.
Here is the code:
$this->crud->addField([ // select_from_array
'name' => 'manager',
'label' => "Manager Name",
'type' => 'select_callback', // Custom field type of select2
'entity' => 'Manager',
'attribute' => 'name',
'model' => 'App\Models\Manager',
'scope' => 'manager'
// 'allows_multiple' => true, // OPTIONAL; needs you to cast this to array in your model;
], 'update/create/both');
And in Model.php
public function scopeManager($query)
{
return $query->where('gym_code', Auth::user()->gym_code);
}
But it is not working!!
Thanks
I found the answer in the same link that I suggested in Question.
In the link #thplat answered a change in select_callback.blade.php
For the select_callback view I took the select view and changed only one line there.
We go from:
#foreach ($field['model']::all() as $connected_entity_entry) to #foreach ((isset($field['callback']) ? $field['callback']() : $field['model']::all()) as $connected_entity_entry).
public function index1()
{
$g = Request::Input('grade');
$s = Request::Input('subject');
if(strcmp($g,'Select A Grade')==0 || strcmp($s,'Select A Subject')==0) {
if (strcmp($s, 'Select A Subject') == 0) {
// Session::flash('msg', 'Please select the Subject.');
return redirect()->back()->withInput();
} else if (strcmp($g, 'Select A Grade') == 0) {
// Session::flash('msg', 'Please select the Grade.');
return redirect()->back()->withInput();
}
}
else{
$u = DB::table('upldtbls')->where('grade',$g)->where('subject',$s)->get();
return view('2Eng',compact('u'));
}
}
Above is the controller method. Main else part executed correctly. But main if part not executed as I wanted. In main if condition I want to stay on the same page if drop box values are equal to that which means when they haven't select an option from drop box. Can any one figure out this mess?
{!! Form::select('Select A Grade', array('' => 'Select A Grade','2' => '2', '3' => '3','4' => '4'), 'Select A Grade', ['class' => 'form-control'])
{!! Form::select('Select A Subject', array('' => 'Select A Subject','English' => 'English', 'Mathematics' => 'Mathematics','Environmental Studies' => 'Environmental Studies'), 'Select A Subject', ['class' => 'form-control']) !!}
The if part is probably not being executed because the condition is not being met. Check that $g or $s is equal to 0 as per you check. If you are simply trying to see if these Input parameters are empty / blank, amend your if statement to:
if(!$g || !$s){
...
}
Also, you should really use Request::Input instead of $_GET, but you need to fix it to one of the below:
# Laravel 5.1.x or earlier
$g = Request::Input('grade');
$s = Request::Input('subject');
or
# Laravel 5.2.x or later
$g = $request->input('grade');
$s = $request->input('subject');
UPDATE
The issue is with your select boxes. You have incorrectly named them, and you would have noticed this if you carried out some basic debugging. Update them as follows:
{!! Form::select('grade', array('' => 'Select A Grade','2' => '2', '3' => '3','4' => '4'), null, ['class' => 'form-control'])
{!! Form::select('subject', array('' => 'Select A Subject','English' => 'English', 'Mathematics' => 'Mathematics','Environmental Studies' => 'Environmental Studies'), null, ['class' => 'form-control']) !!}
i.e. the first parameter should be the name of the field, which gets passed to $_GET. After updating the form, please update the if statement to my suggestion above.
I have a general question.
I have a search form in larvel which returns results form the database.
in these i have an input field to enter a price if price is == 0
what my problem is when i enter price and submit it returns to the search page without my previous search results i.e it doesn't refresh the same page with results and the newly updated field etc.
form in view
{{ Form::open(['action' => 'price_input'])->with($gyms) }}
{{ Form::text('enter_price', null, ['class' => 'form-control', 'size' => '50', 'id' => 'enter_price', 'autocomplete' => 'on', 'runat' => 'server', 'required' => 'required', 'placeholder' => 'enter price!', 'style' => 'margin-bottom: 0px!important;']) }}
{{ Form::submit('Search', ['class' => 'btn btn- primary', 'style' => 'margin-left: 10px;']) }}
{{ Form::close() }}
route
Route::post('/', [ //not used yet
'as' => 'price_input',
'uses' => 'PagesController#priceUpdate'
]);
Model
public function priceUpdate($gyms)
{
if (Input::has('enter_price'))
{
$price = Input::get('enter_price');
Gym::updatePrice($price);
return Redirect::back()->withInput();
}
Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gym);
}
not bothering with model as that works fine.
any ideas guys?
Thanks for your answer,
i have changed my controller to this
public function priceUpdate($gyms)
{
if (Input::has('enter_price'))
{
$price = Input::get('enter_price');
Gym::updatePrice($price);
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
}
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
}
but when i run it i get
Missing argument 1 for PagesController::priceUpdate()
with the $gyms being passed into the method.
if i take out the $gyms that goes away but not sure if its still being passed with session or not, sorry im a novice.
orignally i had a search box which when run returns
return View::make('pages.home')->with($data);
what is the difference between that and
return View::make('pages.home')->with($data);
when i do the above line it returns to the search page with no search options from before update the form, any ideas?
Currently, you are just retrieving an existing session and doing nothing with it. You need to do:
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
Or
return Redirect::to('pages.home')->with('gyms', Session::get('gyms'));
Then you can access the gyms in the view with $gyms.
Alternatively, you could access Session::get('gyms') in the view as well.
Also, not sure if it's just the way you pasted it here, but you have an unnecessary space before the ->with. Just wanted to make sure that's not part of the issue, too!
