I have the following on com_show/views/tmpl/default.php:
function CategoryItems(){
$("button").click(function() {
var ids = this.id;
var u = "<?php echo JURI::root();?>index.php?option=com_show&controller=names&task=showName&id=" + ids;
jQuery.ajax({
type:'GET',
url: u,
data: { id: ids },
success: function(data) { }
}); //end of ajax
});
return false;
}
And on controller I have the following:
function showName(){
$myid = JRequest::getVar('id', 'no value');
return $myid;
}
The problem is on ajax part. When I try getting the returned value from function 'showName()' in controller 'name', Am always getting 'no value' instead of the id.
Kindly assist,

$('.list-group-item').on('click', function () {
var href = $(this).attr("href");
var arr = href.split('path=');
var cat_id = arr[1];
//alert("hai");
$.ajax({
type: 'post',
url: 'index.php?route=ajax/ajaxcat/index',
data: format_data,
dataType: 'json',
success: function (json) {
if (json['success']) {
//$('#messages').html(json['success']);
alert(json['success']);
}
}
});
});
</script>

i really struggle to get the POST value in the controller .i am really new to this..Please someone share me some light..being in the dark for long hours now.
i had a checkboxes and need to pass all the ids that had been checked to the controller and use that ids to update my database.i don't know what did i did wrong, tried everything and some examples too like here:
sending data via ajax in Cakephp
found some question about same problem too , but not much helping me( or maybe too dumb to understand) . i keep getting array();
please help me..with my codes or any link i can refer to .here my codes:
my view script :
<script type="text/javascript">
$(document).ready(function(){
$('.checkall:button').toggle(function(){
$('input:checkbox').attr('checked','checked');
$('#button').click( function (event) {
var memoData = [];
$.each($("input[name='memo']:checked"), function(){
memoData.push($(this).val());
});
var value = memoData.join(", ")
//alert("value are: " + value);
//start
$.ajax({
type:"POST",
traditional:true;
data:{value_to_send:data_to_send},
url:"../My/deleteAll/",
success : function(data) {
alert(value);// will alert "ok"
},
error : function() {
alert("false submission fail");
}
});
//end
} ); //end of button click
},function(){//uncheck
$('input:checkbox').removeAttr('checked');
});
});
my controller :
public function deleteAll(){
if( $this->request->is('POST') ) {
// echo $_POST['value_to_send'];
//echo $value = $this->request->data('value_to_send');
//or
debug($this->request->data);exit;
}
}
and result of this debug is:
\app\Controller\MyController.php (line 73)
array()
Please help me.Thank you so much
How about this:
Jquery:
$(document).ready(function() {
$('.checkall:button').toggle(function() {
$('input:checkbox').attr('checked','checked');
$('#button').click(function(event) {
var memoData = [];
$.each($("input[name='memo']:checked"), function(){
memoData.push($(this).val());
});
//start
$.ajax({
type: 'POST',
url: '../My/deleteAll/',
data: {value_to_send: memoData},
success : function(data) {
alert(data);// will alert "ok"
},
error : function() {
alert("false submission fail");
}
});//end ajax
}); //end of button click
},function(){//uncheck
$('input:checkbox').removeAttr('checked');
});
});
In controller:
public function deleteAll()
{
$this->autoRender = false;
if($this->request->is('Ajax')) { //<!-- Ajax Detection
$elements = explode(",", $_POST['value_to_send']);
foreach($elements as $element)
{
//find and delete
}
}
}
You need to set the data type as json in ajax call
JQUERY CODE:
$.ajax({
url: "../My/deleteAll/",
type: "POST",
dataType:'json',
data:{value_to_send:data_to_send},
success: function(data){
}
});
Hi so I have a JS file with a function for my button, this button get value from different checkbox in a table. But now i want to get these value on another page (for invoice treatement).
Here is my Script :
$("#boutonfacturer").click(function () {
var checked = $('input[name="id_commande[]"]:checked');
var tab = [];
var jsonobj = {};
checked.each(function () {
var value = $(this).val();
jsonobj.value = value;
tab.push(jsonobj);
});
var data= { recup : tab };
console.log(data);
$.ajax({
type: 'POST',
url: 'genererfacture-facture_groupee.html',
data: data,
success: function (msg) {
if (msg.error === 'OK') {
console.log('SUCCESS');
}
else {
console.log('ERROR' + msg.error);
}
}
}).done(function(msg) {
console.log( "Data Saved: " + msg );
});
});
i use an MVC architecture so there is my controller :
public function facture_groupee() {
$_POST['recup'];
var_dump($_POST['recup']);
console.log(recup);
$this->getBody()->setTitre("Facture de votre commande");
$this->getBody()->setContenu(Container::loader());
$this->getBody()->setContenu(GenererFacture::facture_groupee());
and for now my view is useless to show.
I have probably make mistake in my code.
Thank you.
Nevermind after thinking, I have used my ajax.php page which get my another page thanks to a window.location :
my JS :
$("#boutonfacturer").click(function () {
var checked = $('input[name="id_commande[]"]:checked');
var tab = [];
checked.each(function () {
var value = $(this).val();
tab.push(value);
});
var data = {recup: tab};
console.log(data);
$.ajax({
type: 'POST',
url: 'ajax.php?action=facture_groupee',
data: data,
success: function (idfac) {
console.log("Data Saved: " + idfac);
var id_fac = idfac;
window.location = "ajax.php?action=facture_groupee=" + id_fac;
}
});
});
my php :
public function facture_groupee() {
foreach ($_POST['recup'] as $p){
echo $p; }
I wonder how to get data from database using AJAX in CodeIgniter. Could you please check the code below to find out the reason of problem? Nothing happens when I click on the link from my view.
Here is my view:
<?php echo $faq_title; ?>
Here is my controller:
public function get_faq_data() {
$this->load->model("model_faq");
$title = $_POST['title'];
$data["results"] = $this->model_faq->did_get_faq_data($title);
echo json_encode($data["results"]);
}
Here is my model:
public function did_get_faq_data($title) {
$this->db->select('*');
$this->db->from('faq');
$this->db->where('faq_title', $title);
$query = $this->db->get('faq');
if ($query->num_rows() > 0) {
return $query->result();
} else {
return false;
}
}
Here is my JavaScript file:
$(".faq_title").click(function() {
var title = $(this).text();
$.ajax({
url: 'faq/get_faq_data',
data: ({ title: title }),
dataType: 'json',
type: 'post',
success: function(data) {
response = jQuery.parseJSON(data);
console.log(response);
}
});
});
Try this:
$(function(){ // start of doc ready.
$(".faq_title").click(function(e){
e.preventDefault(); // stops the jump when an anchor clicked.
var title = $(this).text(); // anchors do have text not values.
$.ajax({
url: 'faq/get_faq_data',
data: {'title': title}, // change this to send js object
type: "post",
success: function(data){
//document.write(data); just do not use document.write
console.log(data);
}
});
});
}); // end of doc ready
The issue as i see is this var title = $(this).val(); as your selector $(".faq_title") is an anchor and anchors have text not values. So i suggested you to use .text() instead of .val().
The way I see it, you aren't using the anchor tag for its intended purpose, so perhaps just use a <p> tag or something. Ideally, you should use an id integer instead of a title to identify a row in your database.
View:
<p class="faq_title"><?php echo $faq_title; ?></p>
If you had an id integer, you could use a $_GET request an receive the id as the lone parameter of the get_faq_data() method.
Controller:
public function faqByTitle(): void
{
if (!$this->input->is_ajax_request()) {
show_404();
}
$title = $this->input->post('title');
if ($title === null) {
show_404();
}
$this->load->model('model_faq', 'FAQModel');
echo json_encode($this->FAQModel->getOne($title));
}
FAQ Model:
public function getOne(string $title): ?object
{
return $this->db->get_where('faq', ['faq_title' => $title])->row();
}
JavaScript:
$(".faq_title").click(function() {
let title = $(this).text();
$.ajax({
url: 'faq/faqByTitle',
data: {title:title},
dataType: 'json',
type: 'post',
success: function(response) {
console.log(response);
}
});
});
None of these snippets have been tested.
I am doing a delete on a table using jquery,
$('table#chkbox td a.delete').click(function()
{
if (confirm("Are you sure you want to delete this row?"))
{
var id = $(this).parent().attr('id');
var parent = $(this).parent().parent();
$.ajax(
{
type: "POST",
url: "<?php echo base_url().'index.php/libraryController/librarydelete' ?>",
data: { 'id': id },
cache: false,
success: function()
{
parent.fadeOut('slow', function() {$(this).remove();});
}
});
}
});
I am getting the id value correctly but my data parameter doesn't get passed to my controller,
function librarydelete($id)
{
$del = $id;
echo $del;
$this->librarymodel->deletebook_issue($id);
$this->session->set_flashdata('response','Deleted successfully');
redirect('libraryController/loadmagazinedetails');
}
Any suggestion...
I am getting the error,
Missing argument 1 for libraryController::librarydelete() and Undefined variable: id
Your are posting the data, so you can get the id like this:
function librarydelete()
{
$del = $_POST['id'];
echo $del;
$this->librarymodel->deletebook_issue($_POST['id']);
$this->session->set_flashdata('response','Deleted successfully');
redirect('libraryController/loadmagazinedetails');
}
Looks like you are using codeigniter, so this would be even better:
$del = $this->input->post('id');
Change id to $id in controller function parameter
means, your function should be
function librarydelete($id)
{
$del = $id;
echo $del;
$this->librarymodel->deletebook_issue($id);
$this->session->set_flashdata('response','Deleted successfully');
redirect('libraryController/loadmagazinedetails');
}
Perhaps it is because you are using the variable name 'data' twice. Try renaming var data to var mydata.
The way you are passing data is wrong. This is the way you should be setting data.
var data= {id: id };
in your case let me not use the variable in the post action and show you how its done.
$.ajax(
{
type: "POST",
url: "<?php echo base_url().'index.php/libraryController/librarydelete' ?>",
data: {id:id},
cache: false,
success: function()
{
parent.fadeOut('slow', function() {$(this).remove();});
}
});
Edit: After you modified your code to pass data the right way.
Hey I have not followed MVC framwework in php. but since you are doing a post on the action you can always get the data the following way:
$id=$_POST['id']
and then you can use this id.
Also if you still want to use the function:
function librarydelete($id)
{
$del = $id;
echo $del;
$this->librarymodel->deletebook_issue($id);
$this->session->set_flashdata('response','Deleted successfully');
redirect('libraryController/loadmagazinedetails');
}
just modify the uri action to existingurl+/ i.e append the id to the end and in your route map (if there exists something like this in php in .nets implementation there is 1) just add that route.
