JQuery :

$(document).ready(function(){
$("#fm").on('submit',function() {  // this code for form
	var fsb = $(this).serialize();
      $.ajax({   
        type: "POST",
        url: "<?php echo base_url('index.php/product/add');?>", 
        data : fsb,
        dataType: "html",         
        success: function(response){                    
            $("#cart-info").html(response); 
        }
      });
   });  
});

this my php code on controller(using Code Igniter)

 function add() {
      $id = $this->input->post('product_code');
      $this->db->where('product_id',$id);
      $query = $this->db->get('product');
      $stock = $query->row()->stock;

      echo $stock;  // show stock of product
 }

this on views :

<div id="cart-info">This code supposed changed when user submit form on above</div>

<form id="fm">
   <input type="text" name="product_code" value="<?php echo "A100";?>" /> <!-- this code for product id -->
   <button>TEST</button>

Hello everyone,

have simple codeigniter code :

function example($id) {   if(empty($id)) {          redirect(base_url('index.php/example'));   } }

this code $id is empty it will redirect automatically on page that determined.

This work on localhost, but after I uploaded on hosting this code didn't work it will show :

Missing argument 1 for Example::example()

and

Cannot modify header information - headers already sent by (output started at /srv/disk2/602761/www/example.com/system/core/Exceptions.php:189) 

I had ask to my hosting and they answer to me this probably because they prohibits me to use .htaccess because my hosting is free.

Q :Is that true?

please answer

Thanks

Hello everyone

usually on codeigniter to retrieve value we use:

$this->session->userdata('sessionname');

and value from this session can be displayed on class moreover on views for example :

  class example extends CI_Controller {    function __construct() {    }  function example() {       if($this->session->userdata == 0) {      echo 'ok';      } else {      echo 'no';       }   $data['value'] = this->session->userdata('sessionname');  }  }

but how to get value from native session data generated by views ?

for example :

 $qty = $_SESSION['cart'][$p_id]['quantity'];

so that, on class it can be displayed like this :

 class example extends CI_Controller {    function __construct() {    }  function example() {       if($_SESSION['cart'][$p_id]['quantity'] == 0) {      echo 'ok';      } else {      echo 'no';       }   $data['value'] = $_SESSION['cart'][$p_id]['quantity'];  }  }

I had try to retrieve / get value from $_SESSION[] on class but it didn't work.

Q : What I must do so that I can retrieve value from $_SESSION[], so that I can insert them into database using function $this->db->insert('nameDB',$data);

please help me

Thanks

Hello everyone,

I have a code :

index.php

<html><head></head><body><form action="update.php" method="post">   <label>Name</label>  <input type="text" name="test"  />  <select name="activate">    <option value="on">ON</option>    <option value="off">OFF</option>  </select><button>Update</button></form></body></html>

usually if we want to update we put this code :

update.php

<?php$test = $_POST['test'];$activate = $_POST['activate'];mysqli_query($connect,"update name_table set status='$activate' where name ='$test'")?>

Q : how to set ajax so that user no need to press submit button, but only choose 'ON / OFF' on select option so the update script (on update.php) can be executed?

please help me

Thanks

Hello thanks for answer

but sorry I'm rather confuse with new code, I think I need to show all of my file :

cart.php (past code before update)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>Portofolio Book Store</title><?php include('template/css_style.php'); ?><?php include('template/javascript_library.php');?><script type="text/javascript">$(function() {           $.ajax({               type: 'GET',               url: '<?php echo base_url('index.php/user/ajax');?>',               data: {ScreenWidth: $(window).width()},              success: function(data) {               // alert(data);               $('#php_screen_width').html(data);             }           });        });</script></head><body>

ajax.php

<?php$jq_ajax_screen_width = $_GET['ScreenWidth'];if ($jq_ajax_screen_width > 960) {  echo 'ok' .$jq_ajax_screen_width ;} else {   echo 'no'.$jq_ajax_screen_width ;}?>

on cart.php if I put code :

<div id ='php_screen_width'></div>

it will shown the result of ajax.php 'ok' if screen width greater than 960px and 'no' if otherwise.

my expecation : I can get the value from jquery ($jq_ajax_screen_width) into cart.php so :

if ($jq_ajax_screen_width > 960) {  echo 'ok' .$jq_ajax_screen_width ;} else {   echo 'no'.$jq_ajax_screen_width ;}

or

if ($jq_ajax_screen_width > 960) {  $value = 'ok';} else {  $value = 'no';}echo $value;

so when I put echo $value like on above, I can get the result correctly.

and finally for details so that I can make :

<?phpif($value=='ok') {  echo 'this ok';}else{  echo 'this no';}?>

on cart.php

please help me

Thank you

Hello everyone,

Guys I think I post wrong question, please see this code :

using javascript / jquery we can get screen size var width = $(window).width(), height = $(window).height();if ((width <= 1023) && (height >= 768)) {document.write('responsive');} else {document.write('no');}

and usually we give value on php variable like this :

<?php$example = 'ok';echo $example;?>

code on above will display 'ok',

Q: how to pass value that generated from Jquery (whether 'responsive' or 'no') into php variable?

so that :

<?php$example = 'value from jquery code';?>

when I put echo command , it will display value from jquery

please help me

Thanks

Hello everyone,

Thanks before for answer, but this code not work when I put this code on code ignitier,

Q : What should I do?

thanks

Hello everyone,

I think all of you know that to detect screen resolution we can't using pure php,

I found tutorial on google but I'm still confuse to use them please see this code:

<? php if ([SCREEN SIZE CODE FROM JQuery] > 960px) {echo 'OK';}ELSE{echo 'no';}?>

for instance this filename is : tes.php.

on that tutorial they only show this :

if( $(window).width() > 960 ){  $.ajax({    url: 'js/nbw-parallax.js',    dataType: "script",    success: function() {        //success    }  });}

Q : about that jquery code, what I must do? (should I put this code on tes.php or should I put this code on another file such test.html or etc?)

note : my expectation only so that if I open tes.php from I can see the result 'ok' if the screen resolution is greather than 960px.

And I got this tutorial from : http://stackoverflow.com/questions/15142902/php-echo-statement-if-screen-is-a-certain-size

please someone help me

Thanks
