I realized a code for a rate system but when I select a vote, nothing change, when I reselect again a vote, it's ok ! BUT when I see my DB on phpmyadmin, the counter of vote has 1 clic in more than the counter of vote that I "echoed" on my page... why this difference of 1?

$(function(){
$('.star').on('mouseover', function(){

You need to do location.reload(); after you the post, not before.
$.post('sys/votar.php',{votar: 'sim', artigo: artigoId, ponto: ponto}, function(retorno){
location.reload();
}, 'jSON');
There is no point to do the extra work inside the callback since you are reloading the page anyway.
Although, I would recommend you change the elements on the page via ajax instead of the crude location.reload();

PHP side :
https://github.com/muaz-khan/RTCMultiConnection/tree/master/demos/SSEConnection
I'm a complete beginner and have built a basic To-Do List application using PHP/jQuery. The application allows the user to add and remove tasks from a list (stored in a MySQL database).
I'm having issues with the delete function. When the delete button is clicked, it removes the task from the list but it must be remaining in the database, as it reappears once the page is refreshed.
I have no idea where I'm going wrong! Any help appreciated. See below code:
index.php :
<!DOCTYPE html>

if($numrows>0) {
while ( $row = mysql_fetch_assoc( $query ) ){
$task_id = $row['task_id'];
$task_desc = $row['task_desc'];
echo '<li><span>'.$task_desc.'</span><img id="'.$task_id.'" class="delete" width="10px" src="images/delete.png" /></li>';

delete_task.php :
<?php
$task_id = strip_tags( $_POST['task_id'] );
require("db_connect.php");
mysql_query("DELETE FROM tasks WHERE task_id='$task_id'");
?>
You have an error in your delete_task function. There is no such attr as 'task_id'. Try to replace
var task_id = $(this).attr('task_id');
With
var task_id = $(this).attr('id');
Besides #IvanGajic answer is correct, also write your delete query like this:
mysql_query('DELETE FROM tasks WHERE task_id="' . $task_id . '"');
I realized a code for a rate system with five hearts. I would like, when I chose the value of my vote, that the system actualize the average because I must update the page for it.. It must be automatic with my code ... where did I wrong?

I am making a product displaying page of an ecommerce website. The products are to be filtered by brands on the basis of brands that are checked by the customer. For this I have used an ajax request everytime a brand is checked. The problem is that the page cannot receive the get variables that i am sending to the same page. The ajax request is not giving any errors and also the chrome debugger side is also not showing any error at all. This is the page:
snapshot of the products page
And this is the code of the page:

I am using alert() in the beforeSend in the ajax request and it returns the correct data as expected. But the PHP section of the page does not received the values. There are no errors on the PHP side or the browser debug window.
I checked your code line by line. and figure out that you have code for ajax inside the function named "filter" function filter().
Now you are calling this filter function on by onclick event of the element with id clear_brands
$('#clear_brands').on('click', function(){
$('.brand_check').removeAttr('checked');
filter();
$('#clear_brands').css('visibility', 'hidden');
});
and by this code i came to know that at the end your ajax call is not being made because you click event was not triggered,
So either you should trigger this event on your document get ready or you have to do it by clicking on that element.
Just think about the flow once.
i was testing your script in my local and
with some modification i have made it working.
did some changes like
at the end of the script i just putted this code below.
$(document).ready(function(){
$('#clear_brands').trigger("click");
});
And ajax call was executed..

Hello stackoverflow,
I am trying to make a search function to search events on a Search API.
The API can be viewed here: http://build.uitdatabank.be/api/events/search?key=AEBA59E1-F80E-4EE2-AE7E-CEDD6A589CA9&q=opera this is the output XML if you search on the word "opera".
I'm still quite a noob at PHP so i"m having a hard time. I used this tutorial/example as help:http://designm.ag/tutorials/deviantart-api-instant-search-app-using-ajax-php/
So I built my code and I ended up getting the error "Error: parsererror" every time I type in a keyword in the text area. Can anyone help me fix this please?
Here is my HTML code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<title>Culture Reminder</title>

<body>
<header>
<h1>Search events</h1>
</header><!-- /header -->
<div id="container">
<div id="searchform">
<h2>Search for culture</h2>
<input id="s" name="s" placeholder="Type in keyword(s)" size="30" type="text" />
</div><!-- /searchform -->
<center id="loader"><img src="images/loader.gif" alt="loading..."></center>
<div id="content">
</div><!-- /content -->

<div id="footer">

<img src="images/searchbutton.gif" />
<img src="images/mylistbutton.gif" />
<img src="images/settingsbutton.gif" />
</div>
</div><!-- /footer -->
</body>
</html>
Here is the Javascript file:
$(document).ready(function(){
var s = $("#s");
var wrap = $("#content");
var delay = 1500;
var keycode;
var timer;
$(s).keydown(function(e){
// clear old page content and reset timer
$(wrap).empty();
clearTimeout(timer);
});
$(s).keyup(function(){
$("#loader").css("display", "block");
timer = setTimeout(startSearch, delay); // end timeout() function
}); // end keyup() event function
function startSearch() {
$.ajax({
type: 'POST',
url: 'ajax.php',
data: "q="+$(s).val(),
success: function(data){
// hide the loader and blur focus away from input
$("#loader").css("display", "none");
$(s).blur();
var code = "<span class=\"results\">Total Results: "+data['total']+"</span>";
$.each(data, function(i, item) {
if(typeof(data[i].title) !== 'undefined') { // check if data is undefined before setting more variables
code = code + '<div class="listing clearfix"><header><h3>'+data[i].title+'</h3><span class="userdata"><span class="date">'+data[i].calendarsummary+'</span>'+'<span class="location">' + data[i].location+'</span>'+'<span class="description">'+ data[i].shortdescription+'</span></span></header></div>';
code = code + '<img src="'+data[i].thumbnail+'" class="thumbnail">';
}
});
$(wrap).html(code);
},
error: function(xhr, type, exception) {
$("#loader").css("display", "none");
$(wrap).html("Error: " + type);
}
}); // end ajax call
}
}); // end ready() function
And here is my ajax.php code:
<?php
header('Content-Type: application/json');
$query = urlencode(stripslashes($_POST['q']));
$keywords = $query;
$xmlurl = "http://http://build.uitdatabank.be/api/events/search?key=AEBA59E1-F80E-4EE2-AE7E-CEDD6A589CA9&q=".$keywords;
$xmlrss = file_get_contents($xmlurl);
$xmlrss = preg_replace('#&(?=[a-z_0-9]+=)#', '&', $xmlrss);
$object = simplexml_load_string($xmlrss);
// setup return array
$return = array();
$i = 0;
// get total number of results, max 60
$total = count($object->list->item);
$return["total"] = $total;
foreach($object->list->item as $item) {
$title = (string) $item->title;
$date = (string) $item->calendarsummary; //url
$loc = (string) $item->location; // authorname
$desc = (string) $item->shortdescription;//authorpic
$thumburl = (string) $item->thumbnail;//authorpic
// configure array data for each item
$return[$i]["title"] = $title;
$return[$i]["calendarsummary"] = $date;
$return[$i]["location"] = $loc;
$return[$i]["shortdescription"] = $desc;
$return[$i]["thumbnail"] = $thumburl;
$i++;
}
$json = json_encode($return);
die($json);
?>
If anyone could help me I would be so grateful. This is a project for school and I'm still learning basic PHP.
Try this code
<?php
header('Content-Type: application/json');
if(isset($_POST['q']))
{
$query = urlencode(stripslashes($_POST['q']));
$keywords = $query;
$xmlurl = "http://build.uitdatabank.be/api/events/search?key=AEBA59E1-F80E-4EE2-AE7E-CEDD6A589CA9&q=".$keywords;
$xmlrss = file_get_contents($xmlurl);
$xmlrss = preg_replace('#&(?=[a-z_0-9]+=)#', '&', $xmlrss);
$object = simplexml_load_string($xmlrss);
// setup return array
$return = array();
$i = 0;
if(isset($object->list->item))
{
// get total number of results, max 60
$total = count($object->list->item);
$return["total"] = $total;
if($total>0)
{
foreach($object->list->item as $item) {
$title = (string) $item->title;
$date = (string) $item->calendarsummary; //url
$loc = (string) $item->location; // authorname
$desc = (string) $item->shortdescription;//authorpic
$thumburl = (string) $item->thumbnail;//authorpic
// configure array data for each item
$return[$i]["title"] = $title;
$return[$i]["calendarsummary"] = $date;
$return[$i]["location"] = $loc;
$return[$i]["shortdescription"] = $desc;
$return[$i]["thumbnail"] = $thumburl;
$i++;
}
$json = json_encode($return);
die($json);
}else{
//count is empty
}
}else{
//object is not ready
}
}else{
//no post data found
}
