I want to store the value "20_2018" (for example) with an id in my database. I want to count clicks on each downloading.
This is what I tried:
<html>
<body>
<a id="20_2018" rel="link1" href="folder.pdf">Download</a>
<script type="text/javascript">
$(document).ready(function(){
$(\'a[rel="link1"]\').click(function() {
$.ajax({
type:'POST',
url: 'send.php', // folder for sending value in id to the database
data: 'id='+$(this).attr("id"), // take the value in the id
async: false
});
return true;
});
</script>
</body>
</html>
Somehow this does not work. How can I implement a click count for downloads?
First, prevent the default action with preventDefault, then send your request. After success, bring them to the file URL.
$(document).ready(function(){
$('a[rel="link1"]').click(function(event) {
event.preventDefault();
// Gets href of the clicked anchor
var href = $(this).attr('href');
$.ajax({
type:'POST',
url: 'send.php',
data: 'id='+$(this).attr("id"),
success: function(){
// After recording click count, bring them there
location.assign(href);
},
error: function(){
alert('failed');
}
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a id="20_2018" rel="link1" href="folder.pdf">Download</a>

I want to increment count field in database when a link is clicked in php file.
So, I've added the following jquery part to my .php file. But still, it doesn't work. Please help!
<body>
click here
<script>
$(function ()
{
$('#click').click(function()
{
var request = $.ajax(
{
type: "POST",
url: "code.php"
});
});
}
</script>
</body>
code.php:
<?php
$conn=mysqli_connect("localhost","root","","sample");
mysqli_query($conn,"UPDATE e set count=(count+1) WHERE sid='1'");
mysqli_close($connection);
?>
You made a several mistakes in your code.
Update
You can send your SID input type text from ajax with data and you can get the value in your php file with the $sid = $_POST['sid'].
<body>
click here
<input type="text" value="" name="sid" id="sid">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(e){
$('#click').click(function(event)
{
var sidvalue = $("#sid").val(); /*from here you get value of your sid input box*/
event.preventDefault();
var request = $.ajax(
{
type: "POST",
url: "code.php",
data: 'sid='+sidvalue ,
success: function() {
window.location.href = 'https://www.google.com/';
}
});
});
});
</script>
After the ajax success response you can make redirect to your desire location.
Code.php
<?php
$conn=mysqli_connect("localhost","root","","sample");
$sid = $_POST['sid']; // use this variable at anywhere you want.
mysqli_query($conn,"UPDATE e set count=(count+1) WHERE sid='1'");
mysqli_close($conn);
?>
in code.php in mysqli_close you should use $conn not $connection.
Go with this code. It might help you. I have just tested all the things in localhost. This is working perfect.
use preventDefault() when click event is called.check jquery :
<body>
click here
<script>
$(function ()
{
$('#click').click(function(e)
{
e.preventDefault();
var request = $.ajax(
{
type: "POST",
url: "code.php"
});
});
}
</script>
</body>
Redirect your link on ajax success. Like this -
<body>
click here
<script>
$(function ()
{
$('#click').click(function()
{
var request = $.ajax(
{
type: "POST",
url: "code.php",
success: function(response){
window.location="http://www.google.com";
}
});
});
}
</script>
I have a page that locates a link inside it and when that link is clicked it should save some data in database.
Besides, I have a file named "add.php" that communicates with the DB and operates well.
In my wordpress page I have added below codes for accessing the add.php file and send some parameters to it.
<a href="javascript:add(true);" >Click Me</a>
<script type="text/javascript">
function add(b){
$(document).ready(function(){
var result = $.ajax({
type: "POST",
url: "add.php",
data: { add: b }
});
result.done(function(msg) {
alert(msg);
});
result.fail(function(jqXHR, textStatus) {
alert( "No such data exists: " + textStatus );
});
});
}
</script>
I had this exact code in an html file and it worked smoothly. but it doesn't work on wordpress page like that.
Plus, the problem is that when I click the link -Click Me- it doesn't do anything.
please tell me where the problem is and how to solve it ?
I would recommend you to use this:
<a href="#" data-add="true" class='hitClick'>Click Me</a>
<!--use data* attributes to pass specific data -->
now in your function:
function add() {
event.preventDefault(); //<------make sure to add it.
var result = jQuery.ajax({
type: "POST",
url: "add.php",
data: {
add: jQuery(this).data('add')
}
});
result.done(function(msg) {
alert(msg);
});
result.fail(function(jqXHR, textStatus) {
alert("No such data exists: " + textStatus);
});
}
jQuery(document).ready(function(){
jQuery('.hitClick').on('click', add); // bind the click and use as callback
});
alright, I have a popup which displays some notes added about a customer. The content (notes) are shown via ajax (getting data via ajax). I also have a add new button to add a new note. The note is added with ajax as well. Now, the question arises, after the note is added into the database.
How do I refresh the div which is displaying the notes?
I have read multiple questions but couldn't get an answer.
My Code to get data.
<script type="text/javascript">
var cid = $('#cid').val();
$(document).ready(function() {
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax.php?requestid=1&cid="+cid,
dataType: "html", //expect html to be returned
success: function(response){
$("#notes").html(response);
//alert(response);
}
});
});
</script>
DIV
<div id="notes">
</div>
My code to submit the form (adding new note).
<script type="text/javascript">
$("#submit").click(function() {
var note = $("#note").val();
var cid = $("#cid").val();
$.ajax({
type: "POST",
url: "ajax.php?requestid=2",
data: { note: note, cid: cid }
}).done(function( msg ) {
alert(msg);
$("#make_new_note").hide();
$("#add").show();
$("#cancel").hide();
//$("#notes").load();
});
});
</script>
I tried load, but it doesn't work.
Please guide me in the correct direction.
Create a function to call the ajax and get the data from ajax.php then just call the function whenever you need to update the div:
<script type="text/javascript">
$(document).ready(function() {
// create a function to call the ajax and get the response
function getResponse() {
var cid = $('#cid').val();
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax.php?requestid=1&cid=" + cid,
dataType: "html", //expect html to be returned
success: function(response) {
$("#notes").html(response);
//alert(response);
}
});
}
getResponse(); // call the function on load
$("#submit").click(function() {
var note = $("#note").val();
var cid = $("#cid").val();
$.ajax({
type: "POST",
url: "ajax.php?requestid=2",
data: {
note: note,
cid: cid
}
}).done(function(msg) {
alert(msg);
$("#make_new_note").hide();
$("#add").show();
$("#cancel").hide();}
getResponse(); // call the function to reload the div
});
});
});
</script>
You need to provide a URL to jQuery load() function to tell where you get the content.
So to load the note you could try this:
$("#notes").load("ajax.php?requestid=1&cid="+cid);
I want to create one page site by change div content with out load new page.
So, I've implemented my code like this:
HTML:
<title>Post title</title>
<body>
<a class="js-post-bt" href="/post/1" data-id="1"></a>
<a class="js-post-bt" href="/post/2" data-id="2"></a>
<a class="js-post-bt" href="/post/3" data-id="4"></a>
<div id="post-container"></div>
</body>
Script
$(function() {
$(".js-post-bt").on("click", function(e) {
var post_id = $(this).attr("data-id");
$.ajax({
url: "post_title.php?id="+post_id,
success: function(data) {
var title = data;
$.ajax({
url: "post.php?id="+post_id,
success: function(data2) {
// how to change url to post/post_id?
document.title = title;
$("#post-container").html(data2);
}
});
}
});
e.preventDefault();
});
});
Is it possible to create only one ajax call and get returned data either title and post data.
ANd how to change browser address to post/post_id after anchor link clicked.
You can use history api in HTML5

If you want to make just one ajax call, which is a good idea, you will also need to change the code on your server.
It should respond a json object:
json_encode( array( "title" => $title, "post_data" => $post_data ) );
And you ajax call becomes:
$(function() {
$(".js-post-bt").on("click", function(e) {
var post_id = $(this).attr("data-id");
$.ajax({
url: "post_title.php?id="+post_id,
dataType: "json",
success: function(json_data){
document.title = json_data["title"];
$("#post-container").html(json_data["post_data"]);
}
});
e.preventDefault();
});
});
Firstly, there have some tag links in my main page. click each one, post value to b.php with jquery.ajax and turn back value in div#result.
b.php have a search box. when search something in it. the result data will still show in the div#result.
my problem is: I know if I will do jQuery ajax in the b.php, I shall write the jQuery code in the first success part. but this only can control one time, when I continue search in the search box, the jQuery not work. I think I met a loop problem. How to solve it?
a.php
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('.click').click(function(){
var value1 = $(this).text();
$.ajax({
url: "b.php",
dataType: "html",
type: 'POST',
data: "data=" + value1,
success: function(data){
$("#result").html(data);
$('#search').click(function(){
var value = $('#search1').val();
$.ajax({
url: "b.php",
dataType: "html",
type: 'POST',
data: "data=" + value,
success: function(data){
$("#result").html(data);
}
});
});
}
});
});
});
</script>
<a rel="aa" class="click">aa</a>
<a rel="aa" class="click">bb</a>
<div id="result"></div>
b.php
<?php
echo $_POST['data'];
?>
<form name="form">
<input type="text" value="" id="search1">
<a name="nfSearch" id="search">search</a>
</form>
When a new element is introduced to the page the jQuery .click() method becomes useless because it can only see elements that were part of the original DOM. What you need to use instead is the jQuery .live() method which allows you to bind events to elements that were created after the DOM was loaded. You can read more about how to use it at the below link.
.live() – jQuery API
$('#search').live('click', function(e) {
// Prevent the default action
e.preventDefault();
// Your code here....
});
First of all i think you should attach the ajax call to the click on the link: the way you are doing right now just execute an ajax call as soon as the page is loaded.
$(document).ready(function(){
//when you click a link call b.php
$('a.yourclass').click(function(){
$.ajax({
url: "b.php",
dataType: "html",
type: 'POST',
data: "data = something",
success: function(data){
$("#result").html(data);
var value = $('#search').val();
$.ajax({
url: "b.php",
dataType: "html",
type: 'POST',
data: "data =" + value,
success: function(data){
$("#result").html(data);
}
});
}
});
});
});
In this way, each time a link with the class of "yourclass" is clicked an ajax call to b.php is sent and if it succed, another call is made (always to b.php). I don't understand if this is what you are looking fo, if you post your html my answer can be better.
In b.php of course you need to echo some html that can be used in the callback
It's strange how your attempting to do two ajax requests like that, surely one is enough. If you need to support multiple text boxes then you just adjust your selectors.
Your whole code can be shortended down to something like this:
$(document).ready(function() {
$('#result').load('b.php', { data: $('#search').val() });
});
So if you wanted to search for the value when clicking on a link (for links within #container):
$('#container').delegate('a', 'click', function() {
// .text() will get what's inside the <a> tag
$('#result').load('b.php', { data: $(this).text() });
});
