In another Yii2 application I used a package called navatech/yii2-roxymce to replace the textarea with HTMl editable box. In the current application I don't want to use it while I want to keep everything easy reusable. In other words, I want a conditional check says that, if the package is installed call it, if not call the ordinary active form textarea.
I have tried class_exists like the following:
<?php
// _form.php code
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\helpers\Url;
use navatech\roxymce\widgets\RoxyMceWidget;
......
<?php if (class_exists('RoxyMceWidget')): ?>
<?= RoxyMceWidget::widget([
'model' => $model, //your Model, REQUIRED
'attribute' => 'content', //attribute name of your model, REQUIRED if using 'model' section
'name' => 'Post[content]', //default name of textarea which will be auto generated, NOT REQUIRED if using 'model' section
'value' => isset($_POST['Post']['content']) ? $_POST['Post']['content'] : $model->content, //default value of current textarea, NOT REQUIRED
'action' => Url::to(['roxymce/default']), //default roxymce action route, NOT REQUIRED
'options' => [//TinyMce options, NOT REQUIRED, see https://www.tinymce.com/docs/
'title' => 'RoxyMCE',//title of roxymce dialog, NOT REQUIRED
'height' => 450,
],
]);?>
<?php else: ?>
<?= $form->field($model, 'content')->textarea(['rows' => 14]);?>
<?php endif; ?>
.....
However, after the installation of navatech\roxymce\widgets\RoxyMceWidget using composer, the conditional statement gives the same result. i.e printing the ordinary activeform text area, so class_exists seems to always return false inspite off the widget is being installed.
Is there any other right way to check if a package is found or not?
You must provide fully qualified namespace for the class.
class_exists('navatech\roxymce\widgets\RoxyMceWidget')
with prs4 you must include namespace:
class_exists('navatech\roxymce\widgets\RoxyMceWidget')
or:
class_exists(RoxyMceWidget::className()) if it already defined in the use statement.
updated: you should use lastest version of yii2-roxymce, current is 2.0.0.1

I'm new in Yii2 framework. To give structure to my web application, I want to put each controller in a subfolder and make a separate controller for each action in each subfolder. Like that one!
controllers
**User**
IndexController
EditController
UpdateController
**Profile**
IndexController
EditController
UpdateController
How can I arrange that in Yii2.
thanks in advance
Well your example is right.
controllers/user/IndexController.php
views/user/index/index.php
Then in IndexController/EditController/UpdateController you have actionIndex and if you run domain.com/user/index or domain.com/user/edit it will execute actionIndex in current controller (IndexController or EditController)
domain.com/user/index = domain.com/user/index/index
and
domain.com/user/edit = domain.com/user/edit/index
Not sure if there are other more effective ways, but one that works would be the following.
Note: This example assumes that you're using https://github.com/yiisoft/yii2-app-advanced but it can work for the basic app also, just changing the namespaces.
So, let's say you say we have a controller, and we want to store some of its actions into different php files.
<?php
// frontend\controllers\SiteController.php
namespace frontend\controllers;
use yii\web\Controller;
class SiteController extends Controller {
public function actions() {
return [
'error' => [
'class' => 'yii\web\ErrorAction',
],
'captcha' => [
'class' => 'yii\captcha\CaptchaAction',
'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
],
'hello-world' => [
'class' => 'frontend\controllers\site\HelloWorldAction',
],
];
}
public function actionIndex() {
// ...
}
So you can see we've got 3 external actions and one internal one.
The first two ones, are framework's tools for Error page and Captcha generation, actually they've inspired my answer.
And the third one, is defined by us:
'hello-world' => [
'class' => 'frontend\controllers\site\HelloWorldAction',
],
So we've named the action and we created our new action class into a separate directory.
<?php
// frontend\controllers\site\HelloWorldAction.php
namespace frontend\controllers\site;
use yii\base\Action;
class HelloWorldAction extends Action {
public function run($planet='Earth') {
return $this->controller->render('hello-world', [
'planet'=>$planet,
]);
}
}
And last, our view:
<?php
// frontend\views\site\hello-world.php
/* #var $this yii\web\View */
use yii\helpers\Html;
$this->title = 'Hello world page';
?>
<h1>Hello world!</h1>
<p>We're on planet <?php echo Html::encode($planet); ?></p>
And seeing it in action:
Update
After posting the answer I realized that maybe you could benefit from another technique also.
The previous answer is good if you want to do just that: Extract actions into individual files.
But, if your application will be of certain size, maybe you should consider using Modules.
You can create them manually or generate them with Gii:
And once generated, include it in your config:
<?php
......
'modules' => [
'profile' => [
'class' => 'frontend\modules\profile\Module',
],
],
......
Modules do just that, group application logic into one directory, controllers, models, views, components, etc.
Two more tips:
Now to access your module, simply visit http://www.your-site.local/profile/default/index, as you can see, it goes like module/controller/action.
And if you want to generate links to actions inside modules, you would do:
<?php
echo Url::to([
'profile/default/index',
'param'=>'value',
]);
?>
Again as you can see we're using module/controller/action as the route.
Last thing, if you're inside a module, let's say profile/picture/edit, and you want to link to Contact page from SiteController, you would do:
<?php
echo Url::to([
'//site/contact',
'param'=>'value',
]);
?>
Note the double slash // at the beginning of the route. Without it, it will generate the url to the current module profile/site/contact.
I have a base extension so i can version my website. That means i have not a controller or a repository on the extension. So what i want to do, is to create my own settings on existing elements. I was experimenting around with a text align values on the header content element.
Keep in mind, there is already a setting for this, but i am just
experimenting.
I figured out how to add them and the values are saved on the database.
What i now want to do, is to take the values and add them as a class on FLUID. This is where i stuck. I can not get the values. Any idea how to do it?
After this guide How to enable header_position in TYPO3 7.6
i manage to get my code that far:
On the folder /Configuration/TCA/Overrides/tt_content.php
use TYPO3\CMS\Core\Utility\ExtensionManagementUtility;
ExtensionManagementUtility::addTCAcolumns('tt_content',[
'header_position_custom' => [
'exclude' => 1,
'label' => 'header position',
'config' => [
'type' => 'select',
'renderType' => 'selectSingle',
'items' => [
['left', 'left'],
['right', 'right'],
['center', 'center']
]
]
]
]);
ExtensionManagementUtility::addFieldsToPalette('tt_content', 'header', '--linebreak--,header_position_custom', 'after:header_layout');
ExtensionManagementUtility::addFieldsToPalette('tt_content', 'headers', '--linebreak--,header_position_custom', 'after:header_layout');
On the folder /Configuration/Typoscript/Constants/Base.typoscript
styles.templates.templateRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Templates/
styles.templates.partialRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Partials/
styles.templates.layoutRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Layouts/
On the /Resources/Private/Extensions/Fluid_styled_content/Resourcs/Private/Partials/Header.html
<h1 class="{positionClass} {header_position_custom} {data.header_position_custom} showed">
<f:link.typolink parameter="{link}">{header}</f:link.typolink>
</h1>
I 've put the class showed just to make sure that i am reading the
file from the path i gave on the constants
File ext_tables.php
TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addStaticFile($_EXTKEY,'Configuration/TypoScript', 'Website Base');
File ext_tables.sql
CREATE TABLE tt_content (
header_position_custom varchar(255) DEFAULT '' NOT NULL,
);
With all these i get my selectbox where i wanted to be and i get the values on the database. That means that if i select the value "Center" in the selectbox, then it will be saved on the database. How can i get this value and use it as class on the FLUID?
Thanks in advance,
You will find your field in the data object.
For inspecting your fluid variables you can use the f:debug-VH:
<f:debug title="the data">{data}</f:debug>
for inspecting all (in the current context) available variables you can debug _all:
<f:debug title="all data">{_all}</f:debug>
Hint: use the title attribute to identify the output
and don't forget to write a get* and set* function for new fields!
I am working in a yii2 project. I have a form with text field. One field in form is length. currently I use text field for that. What I need is a text field for value and followed by a dropdown box in that we can choose cm or inch or pixel like that. How to do that and How to get value in controller.
You can do it by 2 ways:
First,
Take an input field and one dropDownList using html helper class or you can create simple dropDownList using html
<?= $form->field($model, 'length')->textInput(['maxlength' => 255]); ?>
<?= Html::dropDownList('length_type', null,[ 'cm' => 'cm', 'inch' => 'inch', 'pixel' => 'pixel'],['class' => 'form-control','id'=>'length_type']) ?>
if you want to use html helper class than import Html class as below
use yii\helpers\Html;
Now, use length type in controller
if(isset($_POST['length_type']) && $_POST['length_type'] !=null)
{
$len_type=$_POST['length_type'];
// use this variable according to yuor need
}
Second,
decalare varibale length_type in model class
in view,
<?= $form->field($model, 'length')->textInput(['maxlength' => 255]); ?>
<?= $form->field($model, 'length_type')->dropDownList([ 'cm' => 'cm', 'inch' => 'inch', 'pixel' => 'pixel'], ['class' => 'priority_list']) ?>
In controller you can use model variable directry as
$len=$model->length;
$len=$model->length_type;
I was trying to use the Yii2 ActiveForm encodeErrorSummary property because I wanted to put line-breaks on Yii2 validation error messages:
Example code snippet in MODEL file
public function rules()
{
return [['username', 'required', 'message' => 'long message first line here<br> long message last line here']];
}
Example code snippet in VIEW file
$form = ActiveForm::begin(['id' => 'myform',
'encodeErrorSummary' => false
]);
...
echo $form->field($model, 'username');
...
ActiveForm::end();
Official Yii2 Documentation describes encodeErrorSummary property as:
Whether to perform encoding on the error summary.
but it seemed not suitable for that in my case... Maybe it's me misunderstanding something (...error summary)?
So... what is it intended for, then?
Thank you!
It seems like you need to configure the $fieldConfig property like this:
ActiveForm::begin([
'fieldConfig' => [
'errorOptions' => ['encode' => false],
],
]);
for your requirement. The errorSummary is the summary that you echo with
<?= $form->errorSummary($model) ?>
before or after the form. What you want is a behavior at the field level, while this is an option to disable the encoding at the summary level.
I've been making some basic CRUD pages for my cakePHP app using the HtmlHelper for the views. This is handy for building forms but for date inputs the helper by default generates 3 select boxes for the date which is quite cumbersome to use.
HTML5 introduces the input[type=date] and most browsers now incorporate some nice native interfaces to deal with it; e.g. Chrome produces a nice date-picker for date inputs.
I know it is possible to make the HtmlHelper just make the input a text box instead of the 3 dropdown by doing the following:
echo $this->Form->input('my_date', array('type' => 'text'));
But when I do
echo $this->Form->input('my_date', array('type' => 'date'));
it ignores the 2nd arguement and goes back to the 3 selects.
Is there a way to get the helper to make a date input?
It seem the HtmlHelper has not yet evolved to make use of the "date" input.
If you tell the helper to generate the date input as a text field, adding a jQuery one-liner can convert it to a date input.
So:
echo $this->Form->input('my_date', array('type' => 'text'));
to generate the field. Then:
$('#idOfMyDate').attr('type', 'date');
To change it to a date input.
If anyone has a better way I'd be keen to hear it.
The CakePHP FormHelper uses Widgets to render different input types. For "datetime" types, it uses the DateTimeWidget per default.
To get a regular input with the attribute type="date", you just have to tell CakePHP which widget to use.
In the View (usually App\AppView.php), you can configure the FormHelper:
<?php
namespace App\View;
use Cake\View\View;
class AppView extends View
{
public function initialize() {
$this->loadHelper('Form', [
'widgets' => [
'datetime' => ['Basic'],
],
]);
}
}
?>
The BasicWidget is the most basic widget which is used to render regular text inputs.
Then, in your view, you can just use 'type' => 'date' as expected:
echo $this->Form->input('my_date', array('type' => 'date'));
Or, since CakePHP already sets the type to "date" since the database column is a datetime field you can just leave it like this:
echo $this->Form->input('my_date');
The result is a regular text input with type="date".
For future readers: In the most recent version of CakePHP, you would use the method Form::control instead of Form::input. Everything else still applies.
Try this:
echo $this->Form->text('my_date',array('type' => 'date');
Like this it'll work as a charm
<div class="form-group">
<label for="Description"><?php echo __('Date'); ?></label>
<div class='input-group date' id='datetimepicker1'>
<?php echo $this->Form->input('scheduled_date', array('label'=> false, 'div' => false, 'class'=>'form-control', 'type' => 'text')); ?>
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span>
</div>
</div>
Some explanation:
'div' => false: it's necessary to desable the div rendered by input() FormHelper function
'label' => false: it's necessary to desable the label rendered by input() FormHelper function
Take a look at cake PHP form helper doc for more details
I solved this problem with jquery
PHP
<?= $this->Form->control('birth_date', ['value' => $birth_date->i18nFormat('yyyy-MM-dd'), 'type' => 'text']); ?>
JS
$('#birth-date').attr('type', 'date');
It's obvious that Cake's FormHelper is messing up with <input type "date">. Therefore I solved this problem the following way (in CakePHP 2.x)
Copy FormHelper.php from lib\Cake\View\Helper\
Paste it to app\View\Helper. Now Cake will use your Form Helper instead of its own.
Open the new FormHelper.php, go to protected function _getInput($args) {, search for case 'date': and change it from:
case 'date':
$options += array('value' => $selected);
return $this->dateTime($fieldName, $dateFormat, null, $options);
to:
case 'date':
return $this->{$type}($fieldName, $options);
Cake will now stop transforming <input type="date"> into select boxes.
Keep in mind that with every future release of Cake 2.x you will have to transfer possible changes in Cake's Form Helper into your own Form Helper manually.
