Onchange access codeigniter function - php

I'm trying using jquery onchange. Please take a look:
<script>
$(document).ready(function() {
$("#reservation").change(function() {
var date = $("#reservation").val();
$.ajax({
url: '<?=base_url();?>home',
type: 'POST',
data: {date_search : date},
success: function() {
location.reload();
}
});
});
});
</script>
here is my controller:
else if(isset($date_search)){
$data['var'] = "Range Date";
$explode = explode('-',$date_search);
$start_date = inggris_date($explode[0]);
$end_date = inggris_date($explode[1]);
$data['tgl'] = $this->modelmodel->showdata("select MONTH(tanggal) Tanggal from transaksi where (tanggal between '$start_date' and '$end_date')and outlet = '".$this->session->userdata('username')."' group by MONTH(tanggal)");
$data['angka'] = $this->modelmodel->showdata("select TOP 12 (cash + cc + dc + flash + piutang + reject + disc50) total from transaksi where (tanggal between '$start_date' and '$end_date')and outlet = '".$this->session->userdata('username')."'");
}
$view = 'dummy';
$this->go_to($view,$data);
There is no problem with my query. I'm able to get the result. My question is, how do i refresh my page with the result because when i'm use location.reload the result back to default.
My function above is a part of my controller. Here is the fullscript of my function http://pastebin.com/i5UeypGG

Create another function in your controller place the current logic of the above function in it, in the function for the ajax return a path to the new link,
with the help of window.location when the ajax is complete you redirect to the new controller function.
From what i can tell your function is only displaying data so it may be easier to just use a simple link to a new controller function

From now on. I change my Jquery. I'm using https://github.com/mgalante/jquery.redirect
<script>
$(document).ready(function() {
$("#reservation").change(function() {
var date = $("#reservation").val();
$.redirect('<?=base_url();?>home', {date_search : date});
});
});
</script>
And it's work for me

need help for proper way to write codes for create "loadmore" button and "like" button for posts

I create a load more button for load more posts from the database but when I add like button for that if one time clicks on load more button and then click on the like button, like.php file runs two times and adds two lines in likes table. if I click 2 times on load more then like.php file runs 3 times and...
I want to know how I should create a loadmore button and like the button to works fine.
this is simple of my codes:
posts.php :
<div id="comnts2"></div>
<button id="btn2" >load more</button><script>
$(document).ready(function() {
var comco2 = 2;
var offset2 = 0;
$("#btn2").click(function() {
$.ajax({
method: "POST",
url: "ld_comco.php",
data: { comnco2 : comco2, offset2 : offset2}
})
.done(function(msg2) {
$("#btn2").hide();
} else {
$("#comnts2").append(msg2);
});
offset2 = offset2 + comco2;
});
$("#btn2").trigger("click");
});
</script>
ld_comco.php:
<?php
$comnco2=$_POST['comnco2'];
$offset2=$_POST['offset2'];
$rzp=mysqli_query($conn,"SELECT * FROM `tbl_users_posts` WHERE uid = '$uid' ORDER BY id DESC limit $offset2, $comnco2");
while($rp=mysqli_fetch_assoc($rzp)){
$sid=$rz['id'];
$lik=$rz['lik'];
echo $sid."<br>";
/*like*/
echo'<img class="li_ik1" data-id="'.$sid.'" src="pc3/up.png">'.$lik.' Likes</img>';
?>
</span>
<?php }?>
<script type="text/javascript">
$(document).ready(function() {
var uid=<?php echo $uid;?>;
$(document).on("click", ".li_ik1", function() {
var psid = $(this).data('id');
$.ajax({
method: "POST",
url: "like.php",
data: {psid: psid, uid: uid}
}).done();
});
});
</script>
like.php:
<?php
$id=$_POST['psid'];
$uid=$_POST['uid'];
$Y=mysqli_query($conn,"INSERT INTO `t_plik` (pid,uid) VALUES ('$id','$uid')");
$Q=mysqli_query($conn,"UPDATE `tbl_users_posts` SET lik=lik+1 WHERE id='$id'");
?>
thanks
I think the problem is, that you bind your like button multiple times globally. Each time you load the content from ld_comco.php you also call $(document).on("click", ".li_ik1", ...) in the $(document).ready block, which means you bind all ".li_ik1" buttons on the entire document (but some of them has already been bind).
I would remove the $(document).ready(...) block from the ld_comco.php and move the logic into the posts.php right before you render your content. A further positive aspect is you have your business logic at one place.
KEEP IN MIND: You get a response of buttons in msg2, thats why you do not need to filter $msg2 anymore. But if you wrap your buttons with further html tags in ld_comco.php, your buttons will be on a deeper level, so you need to use a selector again, like you did with .on("click", ".li_ik1", ...).
posts.php
...
var $msg2 = $(msg2);
// Now you bind only the loaded buttons instead of
// the buttons in the entire document for multiple times
$msg2.on("click", function() {
var $element = $(this);
var psid = $element.data('id');
var uid = $element.data('uid');
$.ajax({
method: "POST",
url: "like.php",
data: {psid: psid, uid: uid}
}).done();
});
$("#comnts2").append($msg2);
...
In your ld_comco.php you need to add the data-uid="'.$uid.'" and remove the script block. Then your file should look like this:
<?php
$comnco2=$_POST['comnco2'];
$offset2=$_POST['offset2'];
$rzp=mysqli_query($conn,"SELECT * FROM `tbl_users_posts` WHERE uid = '$uid' ORDER BY id DESC limit $offset2, $comnco2");
while($rp=mysqli_fetch_assoc($rzp)){
$sid=$rz['id'];
$lik=$rz['lik'];
echo $sid."<br>";
/*like*/
echo'<img class="li_ik1" data-id="'.$sid.'" data-uid="'.$uid.'" src="pc3/up.png">'.$lik.' Likes</img>';
}
?>
$("#btn2").trigger("click");
this in posts.php means click the #btn2
so after clicking it, you click it again
$(document).ready(function() {
var comco2 = 2;
var offset2 = 0;
$("#btn2").click(function() {
$.ajax({
method: "POST",
url: "ld_comco.php",
data: { comnco2 : comco2, offset2 : offset2}
})
.done(function(msg2) {
$("#btn2").hide();
} else {
$("#comnts2").append(msg2);
});
offset2 = offset2 + comco2;
});
$("#btn2").trigger("click");
});
</script>

Playing sound when new message comes in

I am making chat for my student group, and I am using AJAX to get my messages like this
//Initial call i make so user do not wait 2 seconds for messages to show
function marko() {
$("#porukice").load("messages.php"); //Load the content into the div
}
marko();
//autorefresh every 2 seconds
var auto_refresh = setInterval(
(function () {
$("#porukice").load("messages.php"); //Load the content into the div
}), 2000);
To send messages I am also using ajax, like this
var frm = $('#form1');
frm.submit(function (ev) {
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: frm.serialize(),
success: function (data) {
document.getElementById("message").value = "";
document.getElementById('play').play();
}
});
ev.preventDefault();
});
This is part of message.php (where messages are generated)
$sql = $conn->query('(SELECT * FROM chat ORDER BY time desc limit 0, 10) ORDER BY time');
while($row = mysqli_fetch_array($sql))
{
$rows[] = $row;
}
foreach($rows as $row){
$time = date('H:i:s', strtotime($row['2']));
echo '['.$time.'] <b>'.$row['0'].'</b>: '.stripslashes($row['1'])."<br/>";
}
I am trying to play a sound when new message arrives>
only solution I came up with is to play a sound when message is sent with
document.getElementById('play').play();
as you can see in above code. I have no clue how to play it when messages are coming, when mysql row is updated.
I saw other answers on stackoverflow but they are not helping me.
NOTICE: $row['1'] is message, $row['0'] is user name and $row['2'] is time.
You could pass, from the PHP script that gets the messages, the value of the last id you got. Then, store it in a jQuery variable, and after you reload the messages, check if the ids are different, if they are (that means a new message came up), play the sound.
For example, after the foreach loop:
return json_encode(array('last_time' => $rows[count($rows)-1][2]));
On your jQuery:
var last_time = 0; // <--- New
var new_time = 0; // <--- New
// Initial call i make so user do not wait 2 seconds for messages to show
function marko() {
$("#porukice").load("messages.php"); //Load the content into the div
// New
if (last_time < new_time) {
document.getElementById('play').play();
last_time = new_time;
}
}
marko();
//autorefresh every 2 seconds
setInterval(function () { // <--- Some edits here
marko(); // <--- Some edits here
}, 2000);
// ....
var frm = $('#form1');
frm.submit(function (ev) {
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: frm.serialize(),
success: function (data) {
document.getElementById("message").value = "";
last_time = new_time; // <--- New
new_time = data.last_time; // <--- New
}
});
ev.preventDefault();
});
I've not tested this, but you're free to do it and let me know.
EDITED to use time instead of id
I fixed this problem by creating separate file called sound.php
Sound.php is answering to get request with json response including date and time of last message
{"last_time":"2017-02-25 17:45:55"}
Then I am calling this file every 2 seconds with ajax, and if last_time has changed i play a sound
var skipped_once = false;
var old_time = 0
var auto_refresh = setInterval(function() {
$.get("sound.php", function(data) {
// if old_time different than last_time play sound
if (old_time != data.last_time) {
//do not play sound on first page load
if (skipped_once) {
document.getElementById('play').play();
out.scrollTop = out.scrollHeight - out.clientHeight;
}
skipped_once = true;
old_time = data.last_time;
}
});
}, 2000);

Can i add CSS style to a echo script alert message? [duplicate]

i am using smoke.js which allows to style the classic alert javascript windows.
All you have to do is place .smoke before the alert ie. smoke.confirm()
The issue I am having is with the ok/cancel callback, it isnt working for me.
This is the example the website shows.
`You can implement these the same way you'd use the js alert()...just put "smoke." in front of it.
The confirm() replacement, however, needs to be used just a little differently:
smoke.confirm('You are about to destroy everything. Are you sure?',function(e){
if (e){
smoke.alert('OK pressed');
}else{
smoke.alert('CANCEL pressed');
}
});
and the code I have is;
$(".upb_del_bookmark").click( function() {
if(smoke.confirm(delete_message)) {
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
It shows the style button and everything but when i click on OK it doesnt perform the function above, nothing happens.
So i rewrote it to
$(".upb_del_bookmark").click( function() {
if(smoke.confirm(delete_message, function(e))) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}}
But now when i click it doesnt even show anything
I am not a programmer, Help!!!!!
If you want to try it go to latinunit.org login with david:123321 and then go to a post and try to add it to your favourites
Update
I tried the following, it shows the window but it doesnt perform the function;
$(".upb_del_bookmark").click( function() {
smoke.confirm(delete_message, function(e) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}})
return false;
});
Here is the js file of the smoke script Link
When i click on cancel the following shows;
Uncaught TypeError: Property 'callback' of object # is not a
function Line:198
Uncaught TypeError: Property 'callback' of object # is not a
function Line:208
The following is what's on those linesof the smoke script;
finishbuildConfirm: function (e, f, box)
{
smoke.listen(
document.getElementById('confirm-cancel-' + f.newid),
"click",
function ()
{
smoke.destroy(f.type, f.newid);
f.callback(false);
}
);
smoke.listen(
document.getElementById('confirm-ok-' + f.newid),
"click",
function ()
{
smoke.destroy(f.type, f.newid);
f.callback(true);
}
);
The builtin javascript alert/confirm functions are synchronous, this is not. You need to handle the result of the confirm using the javascript callback pattern. You pass a function to the smoke.confirm() function which called when you need to respond to an action.
See the following code. The if around the smoke.confirm() has been removed and the handling code is wrapped in the function passed to the smoke.confirm() function.
$(".upb_del_bookmark").click( function() {
smoke.confirm(delete_message, function(e) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}
});
}
I highly recommend reading a little about the callback pattern in javascript. It's very common and understanding it will help you use this plugin and many others.

ajax code stops running when I pass a string from PHP

php
$sortBy = array('upload_date','wall_views','wall_downloads');
$sort = 'upload_date';
if(isset($_GET['sort']) && in_array($_GET['sort'], $sortBy)){
$sort = $_GET['sort'];
}
ajax script
<script type="text/javascript">
var per_page = <?php echo $per_page;?>; //$per_page = 3
var last_page = <?php echo $last_page;?>; //$last_page = 4
var sort = <?php echo $sort;?>; //$sort = upload_date
$(function(){
$('.more').live('click', function(){
var page = $(this).attr('id'); //get the last id
$.ajax({
type: 'GET',
url: 'pagination.php',
data: {page: page, per_page: per_page, last_page: last_page, sort: sort},
success: function(data){
$('#itemContainer').append(data);
}
}); //ajax code end
}); //live end
}); //function end - when DOM is ready.
</script>
the problem occurs when I try to pass a string (upload_date) variable to ajax, I'm not sure if I'm passing the string correctly, this code works fine if only integers/digits are passed into the code. What I'm I doing improperly here? please help.
You'll have to add quotes around string variables. otherwise your generated javascript will look like variable names rather than string literals.
Like so:
var sort = "<?php echo $sort;?>"; //$sort = upload_date

Jquery Select list items in loop using keyup and key down

I am trying to make autosuggest in Jquery,ajax and json to search cities when user register to website.
So far I am able to get results from database.And i appended to list.but now i need to select data using up down and enter keys.
Key down event is adding class to first city. But I want to loop through all results using key up and down and add value to city textbox if user hits enter. I limit data by 5 in php so 5 results are coming in list item.
Here is my code:
$('#city').keyup(function (event) {
var input_query = $(this).val();
$.post("get_city.php", {
"query": input_query
}, function (data) {
$('#cityres').html("");
$.each(data, function (i, item) {
$('#cityresults').append("<li>" + item.city + "</li>");
});
}, "json");
//below code is for key event
var key = gtKeycode(event);
if (key == 40) {
// I am not sure i need to do this way
$('li').first().addClass('SelectedCity');
}
});
function gtKeycode(e) {
var code;
if (!e) var e = window.event;
if (e.keyCode) code = e.keyCode;
return code;
}
i think i have now the solution for your problem hope this will help you..!
I made a php file that echo out json encode just list this:
//PHP "action.php?action=show"
e.g $option[] = array(
'option0'=>".Choose an option",
'option1'=>'somepage1',
'option2'=>'somepage2',
'option3'=>'somepage3');
echo json_encode(array('options'=>$option));
I made up html that will be the handler of the output, then will append
<select class="myoptions">
</select> | <span class="optcap"></span>
JS
function selectedOption()
{
var myoptions = $(".myoptions");
$.ajax({
type:'GET',
url:'action.php?action=show',
dataType:'JSON',
success:function(data){
if(data.s==1){
myoptions.empty();
$.each(data.options, function(x,val){
myoptions.append("<option class='option' value='"+val.option0+"'>"+val.option0+"</option>"
+"<option class='option' value='"+val.option1+"'>"+val.option1+"</option>"
+"<option class='option' value='"+val.option2+"'>"+val.option2+"</option>"
+"<option class='option' value='"+val.option3+"'>"+val.option3+"</option>");
});
}
}
});
}
$(document).ready(function(){
selectedOption();
$(".myoptions").keyup(function(){
var option = [];
$("option.option:selected").each(function(x){
option[x] = $(this).val();
});
$(".optcap").html("["+option+"]");
});
});
