Alright. I was still missing the following code from you, so you'll have to add these yourself:
The HTML element with parameter id="id" needed for $('#id').val(text.id);
The HTML element with parameter id="url1" needed for $('#url1').val(text.url);
The PHP response code for JS function showdata(); inside feeds.php
Since I don't have your database here, I was unable to test the code. It should work fine, but if anything is wrong, just let me know:
PHP file: index.php

include_once("pdo.class.php");

I would normally have two scripts (.php) files.
One to display the form and one to catch the submission (possibly via ajax)
You can have both in the same .php file but then you'd want to check before outputting any text whether you have any POST data to process.
If you go with two files
view file:
<html>
<body>
<form method="POST" action="path/to/formname_submit.php">
your form fields go here
<input name="somefield"/>
...
</form>
<script>
//your jquery code
....
</script>
<body>
</html>
submit file
<?php
if (empty($_POST['id'])){
die("no ID");
};
if (empty($_POST['editvalue'])){
die("no editvalue");
}
//get a database connection
$db = mysqli(DBHOST,DBUSER,DBPASS,DBNAME);
$db->set_charset("utf8");
// read in the POST data
//should do some more validation / anti SQL injection
$editvalue = $db->escape_string($_POST['editvalue']);
$id = intval($_POST['id']);
$sql = "UPDATE sometable SET `field` = '$editvalue' WHERE id=$id";
if ($db->query($sql)){
echo 'Success';
}
else {
echo 'UPDATE ERROR:'.$db->errno.': '.$db->error;
}
your jquery can now send the data to the second script and see if the data coming back from the call is 'Success' and display an error if it's not.

AJAX Post request working only on Web Console (Preview)

I have a really simple ajax request to "send" the ID of an element the user clicks on the webSite. The script is working only on the Web Console (in the Network -> Preview section). This happens in every browser.
here's the code:
AJAX REQUEST
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$('.point1, .point2, .point3, .point4, .point5, .point6, .point7').click(function(event) {
var itemid = event.target.id;
$.ajax({
type: 'post',
//url: "index.php",
data: {'itemid' : itemid},
cache : false,
async : true,
dataType: 'html',
success: function(data) {
alert('success');
},
failure: function(data) {
alert('failure');
}
});
});
</script>
PHP Function
<?php
if(isset($_POST['itemid'])){
$itemid = $_POST['itemid'];
echo "success";
$itemid = (int)$itemid;
echo $itemid;
} else{
echo "failure";}
?>
Can you help me with this?
Just adding the image to let you understand better.
UPDATED: Here's the full code, hope it's not too confusionary (still a beginner):
I'm getting the response correct but echo json_encode($d); is not printing.
Btw thank you very much for your support :)
<?php
$d = array();
if(isset($_POST['itemid'])){
if($_POST['itemid'] != ""){
$d['result'] = "success";
$d['itemid'] = (int)$_POST['itemid'];
} else{
$d['result'] = "error";
$d['error'] = "'itemid' was not set.";
}
header('Content-Type: application/json');
echo json_encode($d);
exit();
}
if ( !empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off'){
// La richiesta e' stata fatta su HTTPS
} else {
// Redirect su HTTPS
// eventuale distruzione sessione e cookie relativo
$redirect = 'https://' . $_SERVER['HTTP_HOST'] .

Here is what can work for you. If it does not work then please share your entire code and the response from PHP too.
// jQuery AJAX call should be something like this
$.ajax({
url: 'index.php',
data: {
"itemid": itemid
},
type: "post",
dataType: "json",
success: function(json) {
if(json.success) {
alert("Item ID is " + json.itemid);
} else {
alert("Item ID is " + json.itemid);
}
},
error: function(jqXHR, textStatus, errorThrown) {
alert("Error :: " + textStatus + " :: " + errorThrown);
}
});
// PHP code can be like this
if(isset($_POST['itemid'])){
$itemid = $_POST['itemid'];
echo json_encode(['success' => true, 'itemid' => $itemid]);
} else {
echo json_encode(['success' => false, 'itemid' => 'Not available']);
}

Consider the following.
JavaScript
$("[class*='point']").click(function(e) {
var itemid = $(this).attr("id");
$.ajax({
type: 'post',
url: "index.php?",
data: {
'itemid': itemid
},
cache: false,
async: true,
dataType: 'json',
success: function(data) {
if(data.result == "success"){
console.log("Success", data.itemid);
} else {
console.log("Failed", data);
}
}
});
});
PHP
<?php
$d = array();
if(isset($_POST['itemid'])){
$d['result'] = "success";
$d['itemid'] = (int)$_POST['itemid'];
} else{
$d['result'] = "error";
$d['error'] = "'itemid' was not set.";
}
header('Content-Type: application/json');
echo json_encode($d);
?>
In a lot of cases, it's better to pass JSON data back. It's easier for JavaScript to handle it. So we build an array of data that we want to pass back to AJAX request and encode it as JSON.
When we make the AJAX Post, PHP will result in a Successful response. You're welcome to catch an error, this would happen with 400 or 500 Status result from the PHP call. You can also see this in your Web Console.
We're going to get a JSON Object back from PHP, either:
{
result: "success",
itemid: 2
}
Or:
{
result: "error",
error: "'itemid' was not set."
}
In JavaScript, we can use dot notation to access the elements of the object. You can also access it like this:
if(data['result'] == "success")
Dot notation is advised.
Update 1
In your PHP File, you will want a different structure. You're going to have to perform some actions before the HTML is presented to the Browser.
<?php
$d = array();
if(isset($_POST['itemid'])){
if($_POST['itemid'] != ""){
$itemid = (int)$_POST['itemid'];
} else{
$d['result'] = "error";
$d['error'] = "'itemid' was not set.";
}
$d;
// Connect to SQL
// Query DB for Table Data ...WHERE itemId = '$itemid'
// Store resultset to $d
header('Content-Type: application/json');
echo json_encode($d);
exit();
}
if ( !empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off'){
// La richiesta e' stata fatta su HTTPS
} else {
// Redirect su HTTPS
// eventuale distruzione sessione e cookie relativo
$redirect = 'https://' . $_SERVER['HTTP_HOST'] .
$_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $redirect);
exit();

PHP AJAX Delete Record - deletion only works 1 time

I am deleting records with ajax and php. When I click the button it erases the record but when I click to delete another record it does nothing. What am I doing wrong?
HTML
<form id="prop_remove">
<input type="hidden" name="id" id="last_id" value="<?php echo $id; ?>">
<input type="hidden" name="user" id="last_user" value="<?php echo $user; ?>">
<input type="button" name="submit" id="last_prop" class="button fullwidth margin-top-5" value="Delete">
</form>
AJAX
<script>
$(document).ready(function() {
$('#last_prop').click(function() {
var id = $('#last_id').val();
var user = $('#last_user').val();
$.ajax({
url: "delete.php",
method: "POST",
data: {
ilan_id: id,
ilan_user: user
},
success: function(response) {
if (response == 1) {
$('#last_prop').closest('tr').css('background', 'tomato');
$('#last_prop').closest('tr').fadeOut(800, function() {
$(this).remove();
});
} else {
alert('Invalid id');
}
}
});
});
});
</script>
PHP
<?php
require_once 'config.php';
$id = $_POST['ilan_id'];
$user = $_POST['ilan_user'];
$checkRecord = "SELECT * FROM last_tbl WHERE id = '$id' AND user = '$user'";
$check_result = mysqli_query($conn, $checkRecord);
$totalrows = mysqli_num_rows($check_result);
if($totalrows > 0){
$delete_sql = "DELETE FROM last_tbl WHERE id = '$id' AND user = '$user';";
$delete_result = mysqli_query($conn, $delete_sql);
echo 1;
exit;
}
?>

Your problem is that you're overwriting the HTML element IDs. You can remove your forms and use a single button instead, and pass data through the data attribute of the buttons.
Replace your form by a single button
<button class="button fullwidth margin-top-5 last_prop" data-last-id="<?= $id; ?>" data-last-user="<?= $user; ?>">Delete</button>
Then adapt your jQuery to use the class last_prop instead of the ID, and fetch the values from the data attributes we set above.
<script>
$(document).ready(function () {
$('.last_prop').click(function () {
var id = $(this).data('last-id');
var user = $(this).data('last-user');
$.ajax({
url:"delete.php",
method: "POST",
data: {ilan_id: id, ilan_user: user},
success:function(response){
if (response == 1 ){
$('#last_prop').closest('tr').css('background','tomato');
$('#last_prop').closest('tr').fadeOut(800,function(){
$(this).remove();
});
} else {
alert('Invalid id');
}
}
});
});
});
</script>
Also, your query can be reduced to one (you don't need that SELECT), and should be with a prepared statement.
<?php
require_once 'config.php';
$id = $_POST['ilan_id'];
$user = $_POST['ilan_user'];
$sql = "DELETE FROM last_tbl WHERE id = ? AND user = ?;";
$stmt = $conn->prepare($sql);
$stmt->bind_param("ss", $id, $user);
$stmt->execute();
if ($stmt->affected_rows) {
// rows were deleted
echo 1;
}
$stmt->close();

}
$json_data = array(
"msg" => $msg,
);
echo json_encode($json_data); // send data as json format
die;
?>

Why is php script not deleting the table?

I've quickly made a page that shows the current items in the database. I've created the function to adjust stocks levels but I am now trying to add the function to delete items. For some reason all it does is reduce the stock level to 0 but doesn't delete the item from the database.
Also would it be possible/better to put the code the generates the table into another file and load it here? As I need it to auto update when you run either the stock update or deletion function.

You are not binding to a submit event on the delete action, you have a typo
$('#deleteItem').on('dsubmit',function(e){

The form is just submitting instead.

PHP variable not being passed to AJAX call?

Im trying to get my PHP script called from AJAX (that is in my main php file).
Here's an example of what it is supposed to do: http://jsfiddle.net/xfuddzen/
The HTML source code shows only desk_box DIV being created (which is in my main.php). station_info DIV (being created in the display_station.php) is not there. How can I fix this? thanks in advance
Problem: DIVs from my display_stationinfo.php are not being created by using the AJAX call.
main.php with JQuery/AJAX part:
<div id="map_size" align="center">
<?php
//didsplay Desk stations in the map
while($row = mysqli_fetch_assoc($desk_coord_result)){
//naming X,Y values
$id = $row['coordinate_id'];
$x_pos = $row['x_coord'];
$y_pos = $row['y_coord'];
//draw a box with a DIV at its X,Y coord
echo "<div class='desk_box' data='".$id."' style='position:absolute;left:".$x_pos."px;top:".$y_pos."px;'>id:".$id."</div>";
} //end while loop for desk_coord_result
?>
<script type="text/javascript">
//Display station information in a hidden DIV that is toggled
//And call the php script that queries and returns the results LIVE
$(document).ready(function() {
$('.desk_box').each((function(){(this).click(function() {
var id = $(this).attr("data")
$("#station_info_"+id).toggle();
$.ajax({
url: 'station_info.php',
data: { 'id': id },
type: 'POST',
dataType: 'json',
success: function(json) {
$("#station_info_"+id).css({'left':json.x_pos ,'top': json.y_pos}).append('<p>Hello the id is:'+ json.id +'</br>Section:'+ json.sec_name +'</p>');
}//end success
});//end ajax
});//end click
});//end ready
</script>
</div> <!-- end map_size -->
display_station.php (script that I want to call):
<?php
include 'db_conn.php';
//query to show workstation/desks information from DB for the DESKS
$station_sql = "SELECT coordinate_id, x_coord, y_coord, section_name FROM coordinates";
$station_result = mysqli_query($conn,$station_sql);
//see if query is good
if ($station_result === false) {
die(mysqli_error());
}
//Display workstations information in a hidden DIV that is toggled
$html = '';
if($station_result->num_rows > 0){
while($row = $station_result->fetch_object()) {
$id = $row->coordinate_id;
$html .= "<div class='station_info_' id='station_info_$id' style='position:absolute;left:{$row->x_coord}px;top:{$row->y_coord}px;'>Hello the id is:$id</br>Section:{$row->section_name}</br></div>";
}
}
else{
// no results - may want to do something with $html
$html = "no result given";
}
$station_result->free();
$conn->close();
echo $html;
?>

Why dont you filter the coordinate in the query? Like this:
$station_sql = "SELECT coordinate_id, x_coord, y_coord, section_name FROM coordinates WHERE coordinate_id = " . $_GET['coordinate_id'];
And in jquery code:
url: 'display_stationinfo.php?coordinate_id=' + id,

Let's start with your database connection, which should be on a separate secure page.
connect.php:
<?php
function db(){
return new mysqli('host', 'username', 'password', 'database');
}
?>
Obviously, your host will not be 'host'.
Now main.php:
<?php
// only use for PHP on this page for initial page load - target other pages with AJAX
?>
<!DOCTYPE html>
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en' lang='en'>
<head>
<meta http-equiv='content-type' content='text/html;charset=utf-8' />
<title>This is Where Your Title Goes</title>
<script type='text/javascript' src='//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js'></script>
<script type='text/javascript' src='main.js'></script>
<link rel='stylesheet' type='text/css' href='main.css' />
</head>
<body>
<div id='map_container'>
<div id='map_size'>
</div>
</div>
</body>
</html>
Now for main.js:
//<![CDATA[
$(function(){
var ms = $('#map_size');
$.post('main_init.php', {init:'1'}, function(d){
for(var i in d){
var di = d[i], x = di.x, y = di.y;
var sti = $("<div class='station_info_' id='station_info_"+i+"'></div>").css({
left:x,
top:y
});
// HTML id, class, and name attributes cannot start with a number
$("<div class='desk_box' data='"+i+"'>id:"+i+'</div>').css({
left:x,
top:y
}).appendTo(ms).append(sti).click(function(){
var info = $(this).next();
$.post('live_info.php', {station_id:info.attr('id').replace(/^station_info_/, '')}, function(r){
// do stuff with r
info.html('love:'+r.love+'<br />hate:'+r.hate).toggle();
}, 'json');
});
}
}, 'json');
});
// use CSS to do `.desk_box,.station_info_{position:absolute;}`
//]]>
Now for main_init.php:
<?php
if(isset($_POST['init']) && $_POST['init'] === '1'){
include_once 'connect.php'; $db = db(); $json = array();
$q = $db->query("SELECT * FROM table WHERE"); // example only
if($q->num_rows > 0){
while($r = $q->fetch_object()){
$json[strval($r->coordinate_id)] = array('x' => $r->x_coord, 'y' => $r->y_coord);
}
}
else{
// no results
}
$q->free(); $db->close();
echo json_encode($json);
}
else{
// could be a hack
}
?>
Here's what live_info.php might look like:
<?php
if(isset($_POST['station_id'])){
include_once 'connect.php'; $db = db(); $json = array();
// example only - you will only get one `$row` if query is done specific, so while loop is not needed
$q = $db->query("SELECT love,hate FROM some_table WHERE id='{$_POST['station_id']}'");
if($q->num_rows > 0){
$row = $q->fetch_object();
// it's okay to overwrite array in this case
$json = array('love' => $row->love, 'hate' => $row->hate);
}
else{
// no results
}
$q->free(); $db->close();
echo json_encode($json);
}
else{
// may be a hack
}
?>
