autoloading helper library model breake ajax json - lanoux - 01-20-2016

Hy, i am facing a really strange issue when using the autoload.php file.

if i use the $autoload['helper'] = array('myOwnHelper'); inside the config/autoload.php and i make a jquery ajax request, the json isn't render (no object show in console.log ).

But with the same ajax and the loading made inside the controller with $this->load->helper('myOwnHelper'); tadam, all worke fine as it must do (the problem is the same whith autoloading my own model).

Someone have see this stuff before? I had this behavior since CI2, it's not new.

The only manner i have found to bypass this it's to render the request as html, then trim the response Dodgy  which is terribly ugly and not really compatible with some jquery lib.

The other solution it's to load at each page helper and model who normally must be globally initialised.

Any help would be appreciated it's since days i try to solve this feature

ps: i have join an image of what is passing because i am not so sure of my english for the explanation Blush

Does your helper call get_instance()? If so, that's your problem.

RE: autoloading helper library model breake ajax json - lanoux - 01-21-2016

no, i don't call get_instance(), here is the code of the helper


PHP Code:
<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    if(!function_exists('load_js')){
        function load_js($scripts,$init){
            $result = "
            <script type='text/javascript'>
                var deferredJSFiles = [
                '//code.jquery.com/jquery-2.1.4.min.js',
                '//cdnjs.cloudflare.com/ajax/libs/jquery.matchHeight/0.6.0/jquery.matchHeight-min.js',";
            $result .= "'".base_url('assets/js/jquery-ui.min.js')."',";
            $result .= "'".base_url('assets/js/jquery.cookiebar.min.js')."',";
            $result .= "'".base_url('assets/js/classie.min.js')."',";
            $result .= "'".base_url('assets/js/jquery.mmenu.min.all.js')."',";
            $result .= "'".base_url('assets/js/behavior.js')."'";
            $result .= $scripts;
            
            $result .= "];
                function downloadJSAtOnload() {
                    if (!deferredJSFiles.length) return;
                    var deferredJSFile = deferredJSFiles.shift();
                    var element = document.createElement('script');
                    element.src = deferredJSFile;
                    element.onload = element.onreadystatechange = function() { if (!this.readyState || this.readyState == 'loaded' || this.readyState == 'complete') downloadJSAtOnload(); };
                    document.body.appendChild(element);
                    if(deferredJSFiles.length == '0'){";
            $result .= $init;
            $result .= "}
                }
                if (window.addEventListener) window.addEventListener('load', downloadJSAtOnload, false);
                else if (window.attachEvent) window.attachEvent('onload', downloadJSAtOnload);
                else window.onload = downloadJSAtOnload;
            </script>";
            return $result;
        }
    } 


and i have the same problem when i try to auto load this model

PHP Code:
<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Menu_model extends CI_Model{
    
    public function menuPlace($place){
        $res        = $this->db->conn_id->prepare('SELECT * FROM `menu` WHERE  `place` = :place');
        $res->bindParam(':place', $place, PDO::PARAM_INT);
        $res->execute();
        $result     = $res->fetchAll(PDO::FETCH_ASSOC);
        return $result;
    }
    
    public function menuRewrite($rewrite){
        $res        = $this->db->conn_id->prepare('SELECT * FROM `menu` WHERE  `rewrite` = :rewrite');
        $res->bindParam(':rewrite', $rewrite, PDO::PARAM_INT);
        $res->execute();
        $result     = $res->fetchAll(PDO::FETCH_ASSOC);
        return $result;
    }
    
    
} 


RE: autoloading helper library model breake ajax json - lanoux - 01-21-2016

i have try several things, and no way, each time i make an auto loading the json is not interpreted

if i use a construct and put inside the load of helper model library, it make the same behavior

if i load them inside the function in the controller it work

worst, i am enable to load helper model library inside the ajax controller or it breake the json...i am driving nuts...oblige to make procedural stuff inside the controller


this work :
PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Ajaxrequest extends CI_Controller {
    public function standard(){
        $result = $return = array('ok'=>'json');
        
        $this->output
            ->set_status_header(200)
            ->set_content_type('application/json', 'utf-8')
            ->set_output(json_encode($result, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES))
            ->_display();
        exit;
    }
} 


this make the json uninterpreted

PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Ajaxrequest extends CI_Controller {
    public function standard(){
        $this->load->library('show');
        
        $result = $this->show->showstandard();
        
        
        $this->output
            ->set_status_header(200)
            ->set_content_type('application/json', 'utf-8')
            ->set_output(json_encode($result, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES))
            ->_display();
        exit;
    }
}


<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Show {
    function showstandard(){
        $return = array('ok'=>'json');
        
        return $result;
    }
} 

as for the js
Code:
    $.post(
        $('#url').val()+'xhr/ajaxrequest/standard',
        {'token' : $("#hash").val()},
        function(data) {
            console.log(data);
        },
        'json'
    );


exept for this problem of json interpretation all work like a dream, really don't know what i am missing

RE: autoloading helper library model breake ajax json - arma7x - 01-21-2016

Use get_instance()->config->base_url() instead of base_url() in your helper.

RE: autoloading helper library model breake ajax json - lanoux - 01-22-2016

the url is give by base_url() already, try your solution don't change nothing to my problem, this not empech te json to be not interpretated

i have the same problem which is describe here

i solve this problem by not loading the model (or library or helper) which cause the breake of the json format. when you looke at the response given when you use $this->load-> is ÿÿÿÿÿÿ{my json well formated}
