CodeIgniter ajax reloading page issue - javascript

I have a page with ajax pagination on it, I am currently able to check if the session exists and process accordingly. However, I cannot seem to remove the menu or reload the page properly if the session has expired. Only the menu remains and the login page shows in the small area where the table was.
Controller code
public function index()
{
$conditions = array();
$data = array();
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search(array('limit'=>$this->get_per_page()));
$data['user'] = $this->AccountModel->get_person($this->get_person_id());
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('layout/admins/common/header');
$this->load->view('layout/admins/common/navigation');
$this->load->view('layout/admins/common/title');
$this->load->view('layout/admins/common/errors');
$this->load->view('layout/admins/common/search');
$this->load->view('admins/documents/index',$data);
$this->load->view('layout/admins/common/footer');
}
public function search(){
if($this->input->is_ajax_request()){
if(!$this->logged_in()){
$this->index();
}else{
$conditions = array();
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$keywords = $this->input->post('keywords');
if(!empty($keywords)){
$conditions['search']['keywords'] = $keywords;
}
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$conditions['start'] = $offset;
$conditions['limit'] = $this->get_per_page();
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search($conditions);
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('admins/documents/ajax_pagination', $data, false);
}
}
}
My JS Code that is placed in the view
<script>
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (html) {
$('#list').html(html);
$('.loading').fadeOut("slow");
}
});
}
function changeStatus(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/ChangeStatus/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
console.log(result);
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
function deleteDocument(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/Delete/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
</script>

i am assuming $('#list').html(html); code loads the html in the dom. instead of directly sending the html from php you can send a json containing the html as well the login status. like this.
$data = [
'login_status' => 1 // or 0,
'html' => $html // full html your are sending now
];
echo json_encode($data);
then in ajax success.
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (response) {
var data = $.parseJSON(response);
if(data.login_status == 0)
{
window.location.href = 'redirect to login page';
}
if(data.login_status == 1)
{
$('#list').html(data.html);
}
$('.loading').fadeOut("slow");
}
});
}
controller method :
public function search(){
if($this->input->is_ajax_request()){
$conditions = array();
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$keywords = $this->input->post('keywords');
if(!empty($keywords)){
$conditions['search']['keywords'] = $keywords;
}
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$conditions['start'] = $offset;
$conditions['limit'] = $this->get_per_page();
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search($conditions);
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$html = $this->load->view('admins/documents/ajax_pagination', $data, true);
$res['html'] = $html;
$res['login_status'] = ($this->logged_in()) ? '1' : '0';
echo json_encode($res);

How to update database using ajax using checkboxes

I want to do it so when a user clicks a checkbox it sets the tinyint value that's set in the database from 0 to 1 and vice-versa. My ajax.js:
function emailNextWithAddress(chk, address) {
var nextEmail, inside_where;
if (chk.checked === true) {
$.ajax({
url: "marca_enviado.php",
data: address,
type: "get",
success: function () {
nextEmail = document.createElement('input');
nextEmail.id = address;
nextEmail.value = address;
nextEmail.type = 'text';
nextEmail.name = 'email[]';
nextEmail.className = 'insemail';
nextEmail.style.display = 'inline-block';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
},
error: function () {
console.log("Erro!");
}
});
} else {
$.ajax({
url: "desmarca_enviado.php",
data: address,
type: "get",
success: function () {
inside_where = document.getElementById(address);
inside_where.parentNode.removeChild(inside_where);
},
error: function () {
console.log("Erro!");
}
});
}
return false;
}
And the part that I'm trying to update is(dbh.php is the connection to the database):
<?php
include_once 'dbh.php';
$id = $_GET['address'];
$updateEnviado = "UPDATE escolas SET Enviado = '$id'";
$result = mysqli_query($conn , $updateEnviado);
?>
In my index.php the part of the code that's being outputted is:
$execItems = $conn->query("SELECT Nome,EmailGeral,Enviado FROM escolas");
while($infoItems = $execItems->fetch_array()){
echo "
<tr style=\"border: 1px solid black;\">
<td>".$infoItems['Nome']."</td>
<td>".$infoItems['EmailGeral']."</td>
<td><input type=\"checkbox\" ".($infoItems['Enviado']?' checked':' ')." onclick=\"emailNextWithAddress(this, '".$infoItems['EmailGeral']."');\"/></td>
</tr>
";
}
?>
Note that I'm only interested in updating the checkbox.

Please help me Thanks in advance.
Check your config.php if $config['csrf_protection'] = TRUE;
If it is set to true you need to send csrf token with the ajax request.
Add this to your view page.
<input type="hidden" id="hidCSRF" name="<?php echo $this->security->get_csrf_token_name(); ?>" value="<?php echo $this->security->get_csrf_hash(); ?>">
In your js file do the below changes.
$(document).ready(function() {
$('#upload').on('click', function () {
var _csrfName = $('input#hidCSRF').attr('name');
var _csrfValue = $('input#hidCSRF').val();
var file_data = $('#file').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
form_data.append(_csrfName, _csrfValue);
$.ajax({
url: base_url +"beep/upload_file",
dataType: 'text',
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function (response) {
$('#msg').html(response); // display success response from the server

How to show the errors through ajax and Jquery in codeigniter

This is my ajax call
function exportCSV(){
var sampleid = $("#sampleid").val();
var scheme = $("#scheme").val();
var v = $("#v").val();
var date = $("#date").val();
var assignedvalue = $("#assignedvalue").val();
var units = $("#units").val();
var assayvalue = $("#assayvalue").val();
var analyte = $("#analyte").val();
var filename=$("#filename").val();
var sample_error=$("#sample_error").val();
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>" + "import/validate_file",
dataType: 'json',
data: {
sampleid: sampleid,
scheme: scheme,
v: v,
date: date,
assignedvalue: assignedvalue,
units: units,
assayvalue: assayvalue,
analyte: analyte,
filename:filename,
sample_error: sample_error
},
success: function (data) {
console.log(data); //as a debugging message.
}
});
}
and this is my controller
<?php
if (!empty($unit_check) and !empty($analyt) and !empty($sch) and count($sample_id) == count(array_unique($sample_id)) and $assigned_check == '1' and $assay_check == '1') {

I have to show the errors and success message on ajax call.
Right now I'm succeeded in valuating the data and putting it in the database.
But I want to show the success message at the end of the page by clicking the submit button.
And if there is validations error it must shows the errors in that fields at the end of the page
Any help would be appreciated.
Here inside your success method of ajax
success: function (data) {
$("#resultDiv").html(data)
}
Return some real data from your controller in both case success and failed. and based on your data inside success method show your message.
Like:
success: function (data) {
$("#resultDiv").html(data.success) //this requires string to convert your result in string if neccessary
//But you should return a JSON data as msg from your controller
}
You should put a result HTML element for example:
<div id='resultDiv'></div> <!-- to match with #resultDiv -->
Put response data in both condition if success=true and else success=false
In your controller
if(.....){
//what ever check you wanna do
..........
..........
$response['msg']='success';
header('Content-Type', 'application/json');
echo json_encode($response);
}
else{
$response['msg']='failed';
header('Content-Type', 'application/json');
echo json_encode($response);
}
In your ajax
success: function (data) {
$("#resultDiv").html(data.msg)
}
Try something like:
$response = array(
'errCode' = 0,
'errMsg' = 'msg'
);
return this kind of array by json_encode() from php to ajax() call and use it in ajax() success like:
var data = JSON.parse(response);
alert(data.errMsg);
You can also put a check on errCode like:
if(errCode == 0) { something }
if(errCode == 1) { something }

Ajax can't comment on another item in loop

I can comment with only first item in while loop, When I tried to comment with another item it's always display alert box You know you need to write a comment right?. I think it can't get comment text on another item in my loop, What's wrong with my code?
I've got this comment code from this link.
My code:
Ajax in index.php
<script type="text/javascript">
$(function () {
// Alert(event.timeStamp);
$('.new-com-bt').live('click', function (evt) {
$(this).hide();
$('.new-com-cnt').show();
$('#name-com').focus();
});
/* When you click on the cancel button */
$('.bt-cancel-com').click(function () {
$('.the-new-com').val('');
$('.new-com-cnt').fadeOut('fast', function () {
$('.new-com-bt').fadeIn('fast');
});
});
// On post comment click
$('.bt-add-com').live('click', function (evt) {
var comment_on_id = $("input[name=comment_on_id]");
var theCom = $("textarea[name=comment-text]");
var theName = $('#name-com');
