Can't get response after click on a link using jquery/ajax - php

I've a link in my php page. Which I want to send a id request to server. But it doesn't response correctly. Actually, I've got two pages.
a. users.php
b. user_update.php
So I'm trying a send a request to the server using jquery/ajax by user id from users.php page to user_update.php for update the details and get back the successful result to user.php page.
The code is look like this:
<div id="edit_user_details">Edit Details</div>
<script>
$('#edit_user_details').click(function() {
id = <?php echo $uid; ?>
$.ajax({
url: edit_user_details.php,
type: post,
data: id;
success: function(response) {
$('#edit_user_result').html(response);
}
});
});
</script>
But it's not working properly. is there anything I'm missing because of I'm new learning of Jquery/Ajax. :)
Update:
I'm requesting this id in php while loop. It's look like this..
while($search_result = mysql_fetch_array($getUser)){
$uid = (int) $search_result['user_id'];
<div id="edit_user_details">Edit Details</div>
}
<script>
$('#edit_user_details').click(function() {
id = <?php echo $uid; ?>;
$.ajax({
url: 'edit_user_details.php',
type: 'post',
data: {'id' : id},
success: function(response) {
$('#edit_user_result').html(response);
}
});
});
</script>
Is it wrong ? What I'm trying is... I want to update user details base on their id. So what need to do for this ?

you need to create a unique id in loop or create a function and calll it onclick like
<?php while($search_result = mysql_fetch_array($getUser)){
$uid = (int) $search_result['user_id']; ?>
<div id="edit_user_details">Edit Details</div>
<?php }?>
<script>
function myfunc(id) {
id = id;
$.ajax({
url: 'db_search.php',
type: 'post',
data: {'id' : id},
success: function(response) {
$('#edit_user_result').html(response);
}
});
}
</script>

you should end your id initialization with a semi-colon;
id = <?php echo $uid; ?>;
Check the correct way of using ajax in this example: Demo ajax using JQuery

Make changes as shown below and try again..
1: Add 'post' in type.
2: Add ''edit_user_details.php' in url
3: Add semicolon at the end here
<?php echo $uid; ?>;
4: take your id as shown in below code
Updated code :-
<script>
$('#edit_user_details').click(function() {
id = <?php echo $uid; ?>;
$.ajax({
url: 'edit_user_details.php',
type: 'post',
data: {'id' : id},
success: function(response) {
$('#edit_user_result').html(response);
}
});
});
</script>
For more information :-
https://api.jquery.com/jQuery.ajax/#entry-examples

i think you are not declaring var id before
try
<div id="edit_user_details">Edit Details</div>
<script>
$('#edit_user_details').click(function() {
var id = <?php echo $uid; ?>;
$.ajax({
url: edit_user_details.php,
type: post,
data: [id:id],
success: function(response) {
$('#edit_user_result').html(response);
}
});
});
</script>

Check your url inside $.ajax. If you are sending your data to user_update.php then your code should be as follows :
<script>
$('#edit_user_details').click(function() {
id = <?php echo $uid; ?>
$.ajax({
url: user_update.php,
type: post,
data: id,
success: function(response) {
$('#edit_user_result').html(response);
}
});
});
</script>
Just change your url to user_update.php and put a comma(,) after data:id in the place of semicolon(;).

This code will works fine for what you need and with less lines, assuming that the PHP var $uid will be processed on loading the page:
<div id="edit_user_details">Edit Details</div>
<script>
$('#edit_user_details').click(function() {
$.get('edit_user_details.php', 'id=<?php echo $uid; ?>', function(response){
$('#edit_user_result').html(response);
});
});
</script>

Update div in html using Ajax function failed

I'm trying to display the search result of my page under the the search area. So I used AJAX to display the result in a div. but I could'nt get it work.
I have three main pieces, the div, the searchResult page and the ajax function
<input type="text" name="studentName">
<button type="submit" name="searchByName" onclick='get_info();'>بحث</button>
<div id="searchResult"><b></b></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script type="text/javascript">
function get_info() { // Call to ajax function
$.ajax({
type: "POST",
url: "NameSearchResult.php", // Name of the php files
data: {name: <?php echo $_POST['studentName']; ?>},
success: function(html)
{
$("#searchResult").html(html);
}
});
}
and my search Page:
<?php
include_once 'dbConfigBDO.php';
$studentName = $_POST["name"];
$counter=0;
$emptyString = "لايوجد";
$sql = "SELECT * FROM Student";
$result = $conn->query($sql);
$row_count = $result->rowCount();
if ($row_count > 0){
.......... }
Now when I search nothing appears, although it works when I put all the code in one page (which would be messy in term of the appearance of the result!).
From function return the output as per below:
return json_encode($result);
In ajax call use dataType:"json" and show your html
Example ajax call:
$.ajax({
type: "POST",
dataType:"json",
url: "NameSearchResult.php", // Name of the php files
data: {name: $("#studentName").val()},
success: function(html)
change code like this
<input type="text" name="studentName" id="studentName">
<button type="submit" name="searchByName" onclick='get_info();'>بحث</button>
<div id="searchResult"><b></b></div>
<script>
$.ajax({
type: "POST",
url: "NameSearchResult.php", // Name of the php files
data: {name: $("#studentName").val()},
success: function(html)
{
$("#searchResult").html(html);
}
});
}
</script>
inside ajax success method try catch what you are getting
success: function(html)
{
console.log(html);
}
if you getting something then your code must be work.

Load a data from a page to another page using jquery ajax

I have two pages, index.php and block1.php
I wanted to load a data from block1.php to a div #details in index.php
here's my code
index.php
<div id="pop_box">
<div class="close"><span id="close">×</span></div>
<div id="block"></div>
<div id="details"></div>
</div>
block1.php
<script>
$(document).ready(function() {
var lnk;
$('[href]').click(function() {
lnk = '';
lnk = $(this).attr('href');
if (lnk.charAt(1) == "b") {
var lot = lnk;
$.ajax({
url: "2dmap_func.php",
method: "POST",
dataType: "text",
data: {
lot: lot
},
success: function(data) {
//alert(data);
$('index.php #pop_box #details').load(data);
}
});
}
});
});
</script>
as you can see I want to load the data from block1.php to index.php's div#details and this code doesn't work.
$('index.php #pop_box #details').load(data);
In you index.php add following line:
<?php include_once 'block1.php' ?>
In your block1.php change following line:
$('index.php #pop_box #details').load(data);
to
$('#details').html(data); // if data is valid html

onClick Ajax data not working

As i'm building an website that needs Ajax for sending POST methods without refreshing the entire page.
I tried using ajax to send data from an onclick event on an LINK-tag, but the ajax code does seem to send an EMPTY post.
This is the php/jquery/ajax code:
<p id="school_content">
</p>
<script src="js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$(".toggleThis").click(function(){
var Id = $(this).attr('id');
$.ajax({
contentType: "application/json; charset=utf-8",
url: "id_script.php",
type: "POST",
data: {
'school_name': Id,
},
success: function(data){
alert(Id);
},
});
$("#school_content").load("id_script.php");
});
});
</script>
The LINK-tag has the 'id' of the school of wich the information needs to be shown in the PARAGRAPH with 'id' "school_content" by this jquery part: $("#school_content").load("id_script.php"); .
The var Id = $(this).attr('id'); part works, because he's giving me the right school_name in an alert(); if I ask it to.
The id_script.php needs to get this POST in the usual way, but is does not..
The id_script.php code:
<?php
include('connect.php');
header('Content-Type: application/json');
if(isset($_POST['school_name'])){
$Id = $_POST['school_name'];
$extract = mysqli_query($con, "SELECT * FROM school_kaart WHERE school_name='$Id'");
$numro=mysqli_num_rows($extract);
if(mysqli_num_rows($extract) == '1'){
$row = mysqli_fetch_assoc($extract);
echo 'Yes it works!';
}
else{
echo 'Nope, didnt work!';
}
}
else{
echo 'Not posted!';
}
?>
I'm still getting "Not posted!" in the PARAGRAPH I mentioned earlier. What seems to be the problem?
.load is shorthand for an ajax request so you are actually doing 2 request.
The latter isn't sending any data and so it returns 'Not Posted!';
http://api.jquery.com/load/
try
<script src="js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$(".toggleThis").click(function(){
var Id = $(this).attr('id');
$.ajax({
url: "id_script.php",
type: "POST",
data: {
'school_name': Id,
},
success: function(data){
alert(Id);
$("#school_content").html(data);
},
});
//remove this
//$("#school_content").load("id_script.php");
});
});
</script>

Update Mysql records using Ajax/Json isn't working

What I'm trying to do is to edit mysql records using php. I've used Ajax/Json to edit a single record, but the problem is my codes isn't working. I tried to alert the value of input element after I clicked the save button and the alert output is verified. And also I don't get any message in console.
Here's what I got right now. Any help will appreciate.
Index.php
<div class="entry-form1">
<form action="" method="post">
<input type="text" name="id_edit" id="id_edit" class="inputs_edit">
<input type="text" name="approved_edit" id="approved_edit" class="inputs_edit">
<input type="submit" name="save_edit" id="save_edit" value="Save"/>
</form>
</div>
Search.php
$query1 = $mysqli->query(""); // not to include
while($r = $query1->fetch_assoc()){
<td><a href='#' name='".$r['id']."' id='".$r['pr_id']."' class='edits'>Edit</a></td>
}
<script>
$(document).ready(function(){
$(".edits").click(function(){
$(".entry-form1").fadeIn("fast");
//not to include some parts of codes
$.ajax({
type: "POST",
url: "auto-complete.php",
data :edit_post_value,
dataType:'json',
success:function(data){
var requested=data.requested;
var id=data.id;
//send to element ID
$('#id_edit').val(id);
$('#requested_edit').val(requested);
}
});
$("#save_edit").click(function () {
var two = $('#id_edit').val();
var five = $('#requested_edit').val();
alert(five);
$.ajax({
type: "POST",
url: "item_edit.php",
data: "id_edit="+two+"&requested_edit="+five,
dataType:'json',
success: function(data){
console.log(JSON.stringify(data))
if(data.success == "1"){
$(".entry-form1").fadeOut("fast");
//setTimeout(function(){ window.location.reload(); }, 1000);
}
}
});
});
});
</script>
Item_edit.php
<?php
$mysqli = new mysqli("localhost", "root", "", "app");
if(isset($_POST['id_edit'])) {
$id_edit= $_POST['id_edit'];
$requested_edit= $_POST['requested_edit'];
$sql = $mysqli->query("UPDATE pr_list SET requested='$requested_edit' WHERE id='$id_edit'");
if($sql){
echo json_encode(array( "success" => "1"));
}else{
echo json_encode(array("success" => "0"));
}
}
?>
1) First, you're not capturing the click event, because $("# save_edit") is within a function that is not being called. So, you're not even sending the form to the server.
2) Second, the way a form works by default send the data and then reload the page, you must call the preventDefault() function from the event object captured to prevent it, before making the ajax call.
try this:
$(document).ready(function(){
$("#save_edit").click(function (e) {
e.preventDefault(); //prevent a page reload
var two = $('#id_edit').val();
var five = $('#requested_edit').val();
alert(five);
$.ajax({
type: "POST",
url: "/item_edit.php",
data: "id_edit="+two+"&requested_edit="+five,
dataType:'json',
success: function(data){
console.log(JSON.stringify(data));
if(data.success == "1"){
$(".entry-form1").fadeOut("fast");
//setTimeout(function(){ window.location.reload(); }, 1000);
}
}
});
});
});

How can i load php file after sending ajax data

So I have 2 files file1.php with all the php and ajax, and file2.php with only php.
$_POST["there_id"] will be sent from file1.php page to file2.php through ajax.
file1.php code:
<div class="list_items">
<li><p>content here ...</p>
</div>
<div class="content_area">
//load ajax content here
</div>
$(".box").on("click", function(e) {
e.preventDefault();
var there_id = $(this).attr("id");
$.ajax({
url: "indexnew.php",
type: "POST",
data: { there_id : there_id}
});
});
file2.php code:
<div id="file2content>
<?php
$there_id = $_POST['there_id'];
$user_id = 5;
$fetch_data = regular_query("SELECT * FROM contents WHERE
(user_by = :me or user_by + :them) AND (user_to = :me or user_to = :them)",
["me" => $user_id, "them" = $there_id], $conn);
foreach ($fetch_data as $data) : ?>
<li><p>database data here</p>
<?php
endforeach;
?>
</div>
now what i want to do is when file2.php is done with php and list items are available i want to load file2contents to content_area on file1.php.
$(".box").on("click", function(e) {
e.preventDefault();
var there_id = $(this).attr("id");
$.ajax({
url: "indexnew.php",
type: "POST",
data: { there_id : there_id},
success: function(data) {
$('.content_area').html(data);
}
});
});
However, content_area should really be an id rather than a class so that it's unique.
Since you're just returning html, you can simplify it using the .load() function.
$('.box').on('click', function(e) {
e.preventDefault();
var there_id = $(this).attr('id');
$('.content_area').load('indexnew.php', {there_id: there_id});
});
success: function(data) { $(".content_area").html(data); }
adding the above to your AJAX call should do what you want if I understand you correctly.
