laravel 5 - Properly handle TokenMismatchException

In laravel 5 , When the token is expired you could get the TokenMismatchException. So we can avoid the exception and redirect back to the page with some error notification messages is best for the users.

I searched around and could not find a 100% definitive solution to this. I was able to find this bit of code but it does not seem to make any difference: App\Exceptions\Handler.php

public function render($request, Exception $exception){ 

  if ($exception instanceof TokenMismatchException){ 

    return redirect(url()->previous())->with('alert-danger', 

"Oops! Seems you couldn't submit form for a long time. 

Please try again."); 

    }
    return parent::render($request, $exception); 

 }

jQuery push multiple values in input tag

Just set value to input store it in some temporary variable, append the value you want to store and set the value of input to this temporary variable eg.

<input id="user" type="text" name="user" class="form-control" />
<input id="user_id" type="hidden" name="user_id" value="" />

var oldValue = $("#user_id").val();
var arr = oldValue === "" ? [] : oldValue.split(',');
arr.push(yardval);
var newValue = arr.join(',');
$("#user_id").val(newValue);

Yii Form Validation With Ajax submit button

Step 1: @ your controller action

public function actionMyAction()
{       
    $model=new User;             
    $this->performAjaxValidation($model);  

    if(isset($_POST['User']))
    {
        $model->attributes=$_POST['User'];
        $valid=$model->validate();            
        if($valid){

           //do anything here
             echo CJSON::encode(array(
                  'status'=>'success'
             ));
            Yii::app()->end();
            }
            else{
                $error = CActiveForm::validate($model);
                if($error!='[]')
                    echo $error;
                Yii::app()->end();
            }
   }
}

Step 2: @ your view Your form may look like this

<?php
$form=$this->beginWidget('CActiveForm', array(
        'id'=>'user-form',
        'enableAjaxValidation'=>true,
        'action'=>$this->createUrl('myController/MyAction'),
        'enableClientValidation'=>true,
     
));
   ?>
<div class="errorMessage" id="formResult"></div>
<div id="AjaxLoader" style="display: none">
<img src="<?php echo Yii::app()->request->baseUrl; ?>
/images/spinner.gif"></img></div>
<div class="row-user-single">
    <?php echo $form->labelEx($model,'attribute1'); ?>
    <?php echo $form->passwordField($model,'attribute1',
    array('size'=>60,'maxlength'=>500)); ?>
    <?php echo $form->error($model,'attribute1'); ?>
</div>

<div class="row-user-single">
    <?php echo $form->labelEx($model,'attribute2'); ?>
    <?php echo $form->passwordField($model,'attribute2',
array('size'=>60,'maxlength'=>500)); ?>
    <?php echo $form->error($model,'attribute2'); ?>
</div>
<div class="buttons">

 <?php echo CHtml::ajaxSubmitButton('Save',
CHtml::normalizeUrl(array('myController/MyAction','render'=>true)),
    array(
        'dataType'=>'json',
        'type'=>'post',
        'success'=>'function(data) {
            $("#AjaxLoader").hide();  
           if(data.status=="success"){
            $("#formResult").html("form submitted successfully.");
            $("#user-form")[0].reset();
           }
            else{
           $.each(data, function(key, val) {
           $("#user-form #"+key+"_em_").text(val);                                                    
           $("#user-form #"+key+"_em_").show();
           });
           }       
       }',                    
        'beforeSend'=>'function(){                        
              $("#AjaxLoader").show();
         }'
        ),array('id'=>'mybtn','class'=>'class1 class2')); ?>
<?php $this->endWidget();?>

there are only two things to be noted as follows:
1. @ your controller call validate of your model and return a json object if form is invalid
2. @ your view break this json object (OR traverse through it) and show the error messages under respective elements of the form.

Yii2 gridview sum of column value

Here is some of the sample code to get the sum of the column values in the footer in the gridview. It was 100% working in the gridview in Yii2.

All you need to change is the values

 [
   'label' => 'cost',
   'attribute' => 'cost',
   'value' => function ($model, $key, $index, $widget) {
                            return $model->cost;
                    },
   'footer' => $cost,
 ],

The above code should be added in the gridview with footer enabled.

'showFooter' =>true,

Here cost the value which need to be totaled, so you need to change according to your needs. You also need to add the below code in the view page.

<?php
$cost = 0;
if (!empty($dataProvider->getModels())) {
 foreach ($dataProvider->getModels() as $key => $val) {
     $cost += $val->cost;
    }
}
?>

Use this code and calculate sum of values in the footer in the Yii2 Gridview.

Thanks for the code to make it easy. For more refere go to techken.in

jquery difference between map vs each function

The each method is meant to be an immutable iterator, where as the map method can be used as an iterator, but is really meant to manipulate the supplied array and return a new array.

Another important thing to note is that the each function returns the original array while the map function returns a new array. If you overuse the return value of the map function you can potentially waste a lot of memory.

For example:

var items = [1,2,3,4];

$.each(items, function() {
  alert('this is ' + this);
});

var newItems = $.map(items, function(i) {
  return i + 1;
});

// newItems is [2,3,4,5]

You can also use the map function to remove an item from an array.  For example:

var items = [0,1,2,3,4,5,6,7,8,9];

var itemsLessThanEqualFive = $.map(items, function(i) {
  // removes all items > 5
  if (i > 5)
    return null;
  return i;
});
// itemsLessThanEqualFive = [0,1,2,3,4,5]

Datepicker onSelect Issue Fixed

The first time the datepicker is initialized, the original dom element is marked with a new class addition, called hasDatepicker that prevent subsequent initialization/reconfiguration. The way I found to get rid of it is to remove that marker befor doing any modification to the datepicker's configuration. Thus:

$(function() {
   $('#date_caisse').removeClass('hasDatepicker');
   $('#date_caisse').datepicker({
       onSelect: function(dateText, inst) {
           alert('overridden!');
       }
   });
});

Give it a try! Thanks for themarcuz . 

Php - Adding divs to a foreach loop every 4 times

Basically what i need to do is wrap a div around the output of the data every 4 loops.

I have the following loop:

foreach( $users_kicks as $kicks ) {
    echo $kicks->brand;
}

For every 4 times it echos that out i want to wrap it in a  so at the end it will look like so:

<div>
    kicks brand
    kicks brand
    kicks brand
    kicks brand
</div>
<div>
    kicks brand
    kicks brand
    kicks brand
    kicks brand
</div>
<div>
    kicks brand
    kicks brand
    kicks brand
    kicks brand
</div>


Solution:
=========
$count = 1;

foreach( $users_kicks as $kicks )
{
    if ($count%4 == 1)
    { 
         echo "<div>";
    }
    echo $kicks->brand;
    if ($count%4 == 0)
    {
        echo "</div>";
    }
    $count++;
}
if ($count%4 != 1) echo "</div>";

//This is to ensure there is no open div if the number of elements in user_kicks is not a multiple of 4

Opencart - Shipping For Multiple Flat Rates

Do you want a second (or third, or fourth) flat rate for your site’s shipping? OpenCart doesn’t include a shipping method that allows for multiple flat rates by default, but you can easily set up multiple flat shipping options using the built-in Weight Based Shipping extension.

1. In System > Localisation > Geo Zones, set up a duplicate geo zone for each flat rate that you want. For example, if you wanted these three shipping options available to the U.S.:

• Standard: $5.00
• Express: $12.00
• Next-Day: $18.00

then you would create three geo zones all with United States selected as the country, named “Standard”, “Express”, and “Next-Day”.

2. In Extensions > Shipping > Weight Based Shipping, create a rate for each geo zone with a rate (in the format Weight:Cost) like so:
RATE #1

• Geo Zone: Standard
• Rates: 999999:5.00

RATE #2

• Geo Zone: Express
• Rates: 999999:12.00

RATE #3

• Geo Zone: Next-Day
• Rates: 999999:18.00

Don’t forget to enable the extension as a whole in the “General” tab, and each geo zone in its own tab. If you have other geo zones for other purposes then leave those disabled in their tabs. If you need a tax rate applied to the shipping costs, then select the Tax Class in the “General” tab.

3. During checkout, each option will be presented to the customer on the “Delivery Method” step. They are ordered alphabetically by name, so if you need them in a particular order then you should name them accordingly.

4. If you want to remove the cart weight that is attached to each rate title, then you can make the following edit:

IN:

/catalog/model/extension/shipping/weight.php

REPLACE:

$result['name'] . ' (' . $this->language->get('text_weight') . ' ' . $this->weight->format($weight, $this->config->get('config_weight_class_id')) . ')',

WITH:

$result['name']

 
And that’s it! Your OpenCart store now has multiple flat rate shipping options for your customer.
