I know I can use
<?= $form ->field($model, 'subject')
->textInput(array('value' => 'VALUE'))
->label('Titel'); ?>
to prefill a Textfield, but how can I do it for a radioList?
<?= $form ->field($model, 'locations')
->radioList($regionen)
->label('Regionen');
I could use ->textInput again but this transforms the whole List into a single Textfield
Alternativly: Is there a better way to modify a database record? Currently I'm trying to set all values into a new form.
Put the value that you want selected in the locations attribute of your $model and after rendering, it will be pre-selected in the radio list. That is:
$model->locations = ....
I assume that locations is a foreign key to some other table (or maybe a fixed list of strings).
Referring the documentation :
Pass the second parameter, options[] to radioList()
$options = [
'item' => function($index, $label, $name, $checked, $value) {
// check if the radio button is already selected
$checked = ($checked) ? 'checked' : '';
$return = '<label class="radio-inline">';
$return .= '<input type="radio" name="' . $name . '" value="' . $value . '" ' . $checked . '>';
$return .= $label;
$return .= '</label>';
return $return;
}
]
<?= $form->field($model, 'locations')
->radioList($regionen, $options)
->label('Regionen');
Hope this helps..

Hello guys I just want to ask in my project there are three tables product, color and product_color.I insert database using insert_batch then it work fine, when i update product_color table using update_batch then face some problems.Here's my sample code:
Database:
product:id,name,sku...
color:id,color_name
product_color:id,pro_id,color_id
Input Form:
<?php foreach($colors as $color): ?>
<input type="checkbox" class="form-check-input" name="color[]" value="<?php echo $color->color_id; ?>" <?php foreach ($productcolor as $key => $value){ $array[] = $value->color_id;} if(in_array($color->color_id,$array)) echo 'checked'; else ''; ?>>
<label class="form-check-label">
<?php echo $color->color_name; ?>
</label>
<?php endforeach; ?>
Actually i want to pass primary id from product_color table.Here i pass color_id.Have any way to pass primary id from input form;
Here Is my Controller:
$colorBatch = array();
foreach ($color as $colorvalue) {
$colorBatch[] = array(
'id'=>$id
'pro_id' =>$pid,
'color_id' => $colorvalue
);
}
$this->db->update_batch('product_color', $colorBatch,'pro_id');
Where $pid contains product_id;
Is it possible to pass product_color table primary id from input form or Have any better solution to solve this.Sorry for bad english.
Thanks
Please check below code as your array structure is wrong;
$colorBatch = array();
foreach ($color as $key => $colorvalue) {
$colorBatch[$key] = array(
'id'=>$id
'pro_id' =>$pid,
'color_id' => $colorvalue
);
}
$this->db->update_batch('product_color', $colorBatch,'pro_id');
I need Radio Button group in separate place in yii2 like in this question . I can customise the radio button like in this picture
but when I submit the form only the value of last radio is always submitted if last radio button is clicked respective value else null . I am not able to submit previous checked value.
mine form looks like
<div class="cart-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'product_id')->hiddenInput()->label(false) ?>
<?= $form->field($model, 'size_id')->dropDownList(
ArrayHelper::map(Productsize::find()->where(['product_id'=>$id])->all (), 'product_size_id', 'product_size' ),
[ 'prompt'=>'Select size',
'onchange'=>'
$.get( "'.Yii::$app->urlManager->createUrl('cart/lists?id=').'"+$(this).val(),
function( data ) {
$( "#pricetag11" ).val(data);
$( "#pricetaghtml" ).html(data);
});
']); ?>
<?php $colors = Productcolor::find()->where(['product_id'=>$id])->all(); ?>
<h4>Price:</h4> <p id="pricetaghtml" style="color:red;"></p>
Select size to see the price
<?php echo $form->field($model, 'price_id')->hiddenInput(['id'=>'pricetag11'])->label(false)?>
<!-- here is my problem -->
<h4>Color:</h4>
<?php foreach($colors as $color):?>
<div style="background-color:<?= $color->product_color;?>;width:20px;height:20px;padding-left:3px; display: inline-block"> <?= $form->field($model, 'color_id')->radio(['value' =>$color->product_color, 'label'=>'','uncheck'=>'null']); ?></div>
<?php endforeach;?>
<!-- -->
<?= $form->field($model, 'quantity')->textInput(['type' => 'number','min'=>'0','max'=>'9999' , 'placeholder'=>'0']) ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
In my scenario, I have to load color (hexcode) from database table and display in form and need to save the respective code in another table using radio button.
I have tried so many ways to accomplish this task in yii2 but i am not able. i hope someone will point me to the right direction.
I guess this will work,
<?= $form->field($model, 'color_id')->radioList(
$colors,
[
'item' => function($index, $label, $name, $checked, $value) {
$return = '<div style="background-color:'.$value.';width:20px;height:20px;padding-left:3px; display: inline-block">';
$return .= '<input type="radio" name="' . $name . '" value="' . $value . '">';
$return .= '</div>';
return $return;
}
]
)
->label(false); ?>
In my form I update more start and end dates from the same model at once. See the simplified form:
<?php $form = ActiveForm::begin(); ?>
<?php foreach($dates as $i=>$date): ?>
<?= $form->field($date,"[$i]start"); ?>
<?= $form->field($date,"[$i]end"); ?>
<?php endforeach; ?>
</table>
<?= Html::submitButton('Save'); ?>
<?php ActiveForm::end(); ?>
In the model I need to control, if the end date is after the start date:
public function rules() {
return [
[['end'], 'compare', 'compareAttribute' => 'start', 'operator' => '>', 'message' => '{attribute} have to be after {compareValue}.'],
];
}
I tried to change selectors similarly as described in: Yii2: Validation in form with two instances of same model, but I was not successful. I suppose I need to change the 'compareAttribute' from 'mymodel-start' to 'mymodel-0-start' in the validation JS:
{yii.validation.compare(value, messages, {"operator":">","type":"string","compareAttribute":"mymodel-start","skipOnEmpty":1,"message":"End have to be after start."});}
So, I look for something like:
$form->field($date,"[$i]end", [
'selectors' => [
'compareAttribute' => 'mymodel-'.$i.'-start'
]
])
Solution
The solution is based on the answer of lucas.
In the model I override the formName() method, so for every date I have a unique form name (based on ID for the existing dates and based on random number for new dates):
use ReflectionClass;
...
public $randomNumber;
public function formName()
{
$this->randomNumber = $this->randomNumber ? $this->randomNumber : rand();
$number = $this->id ? $this->id : '0' . $this->randomNumber;
$reflector = new ReflectionClass($this);
return $reflector->getShortName() . '-' . $number;
}
The form then looks like this:
<?php $form = ActiveForm::begin(); ?>
<?php foreach($dates as $date): ?>
<?= $form->field($date,"start"); ?>
<?= $form->field($date,"end"); ?>
<?php endforeach; ?>
</table>
<?= Html::submitButton('Save'); ?>
<?php ActiveForm::end(); ?>
Override the formName() method in your model class to make it unique. If you don't want to change your model class, create a subclass of it for the purpose of working for this controller action. After doing this, the html ID and name fields will automatically be unique.
How do I add a value-ess attribute to the form tag?
I want to have:
<form data-abide >
according to: http://foundation.zurb.com/sites/docs/abide.html
I've tried
<?php $form = ActiveForm::begin(['id' => 'contact-form', 'options'=>['data-abide'=>'']]); ?>
but get output:
<form data-abide="ak8hvf-abide" >
Try this:
'options'=>['data-abide'=>true]
Reference: In the framework helper BaseHtml.php file, find ：
function renderTagAttributes
Where :
foreach ($attributes as $name => $value) {if (is_bool($value)) { if ($value) { $html .= " $name"; } } elseif...
...
elseif ($value !== null) { $html .= " $name=\"" . static::encode($value) . '"'; }
...
It is actually behaving as expected - turns out it is the adide.js which adds the extra security token:
https://github.com/yiisoft/yii2/issues/10532#issuecomment-169952232
Thanks everyone for help!
For me, both 'data-abide'=>'' and 'data-abide'=>true works fine...
Could it be something outdated? Can you try run a composer update in your project?
how do I create a dropdown list in joomla 3.1 for a custom component. I try to create custom fields and I would like to use joomlas dropdown with search
my get input method looks
public function getInput() {
$jinput = JFactory::getApplication()->input;
$sub_id = $jinput->get('sub_id');
$db = JFactory::getDbo();
$query = $db->getQuery(true)
->select('*')
->from('#__unis_faculties')
//->join('#__unis_subjects')
->order('faculty_name');
$db->setQuery($query);
$rows = $db->loadObjectList();
if (isset($sub_id)) {
$actual = $db->getQuery(true)
->select('f.id, f.faculty_name')
->from('#__unis_faculties AS f')
->join('LEFT', '#__unis_subjects AS s ON f.id = s.faculty')
->where('f.id = ' . $sub_id);
$db->setQuery($actual);
$actual_row = $db->loadRow();
}
$html = '';
$html .= '<div class="span12 input-prepend">
<span class="add-on">€ </span>
<input class="span4" name="price" id="price" type="text" />
</div>';
$html .= '<field name="" type="list" default="" label="Select an option" description=""><select>';
foreach ($rows as $row) {
$html .= '<option ' . "selected" ? $row->id = $actual_row->id : '' . 'value="' . $row->id . '" >' . $row->faculty_name . '</option>';
}
$html .= '</select></field>';
return $html;
}
but this does not outputs the desired result, the list won't shows up
the actual code is producing the following dropdown but without to show the elements
