Yii2 Gridview pagination losing POST data.

Yii 2.0 General Discussions

Hey there,

I’ve implemented a form filter to filter a GridView dataprovider, that some time can have a lot of fields. Bearing this in mind, GET method is not supported to me because I can receive something like from Apache/Nginx:

So, when I click in any pagination link, I lost the POST data. How to keep my filter without change my HTTP method?!

I saw some approaches using Pjax, something like this:


Pjax::begin(['clientOptions' => ['method' => 'POST']]);

It didn’t work, though.

Since I am not using a regular filter (it is a dynamic filter that I’ve created), I do not use the $model->load method. I used to use somethiing like the following:




$attributes = Yii::$app->request->post('attribute');

$type = Yii::$app->request->post('type');

$filter = Yii::$app->request->post('filter');

Also, you can see in the attached images the ajax sent using PJAX, it doens’t have a POST data.

Thanks in advance

You can add js code

$js = <<< JS
$(document).on('ready pjax:success', function() {
        function updateURLParameter(url, param, paramVal)
        {
        var TheAnchor = null;
        var newAdditionalURL = “”;
        var tempArray = url.split("?");
        var baseURL = tempArray[0];
        var additionalURL = tempArray[1];
        var temp ="";                       
                                                              
        if (additionalURL)                                    
        {                                                     
            var tmpAnchor = additionalURL.split("#");         
            var TheParams = tmpAnchor[0];                     
            TheAnchor = tmpAnchor[1];                         
            if(TheAnchor)                                     
                additionalURL = TheParams;                    
                                                              
            tempArray = additionalURL.split("&");             
                                                              
            for (var i=0; i<tempArray.length; i++)            
            {                                                 
                if(tempArray[i].split('=')[0] != param)       
                {                                             
                    newAdditionalURL += temp + tempArray[i];  
                    temp = "&";                               
                }                                             
            }                                                 
        }                                                     
        else                                                  
        {                                                     
            var tmpAnchor = baseURL.split("#");               
            var TheParams = tmpAnchor[0];                     
            TheAnchor  = tmpAnchor[1];

            paramVal += "#" + TheAnchor;
