I have successfully created a <textarea> that posts content to the database without a need for button or page refresh. However, for design purposes I would like to use an editable <div>. So I've used contenteditable="true". However, the ajax post no longer works with <div>.
My Code:
$(document).ready(function() {
var timer;
$('#about').on('input', function() {
var value = this.value;
clearTimeout(timer);
timer = setTimeout(function() {
var about = $('#about').val().trim();
$.ajax({
url: "comment.php?customer_id=" + "<?php echo $customer_id; ?>",
type: 'post',
data: {
about: about
},
success: function(response) {
$('#cid').val(response);
}
});
}, 2000);
});
});
/* This is comment.php */
<?php
session_start();
require_once 'config/config.php';
require_once 'includes/auth_validate.php';
$cid = $_GET['customer_id'];
$about = $_POST['about'];
$sql = ("UPDATE patient_id SET about = ? WHERE id = ?;");
$stmt = mysqli_stmt_init($conn);
mysqli_stmt_prepare($stmt, $sql);
mysqli_stmt_bind_param($stmt, "si", $about, $cid);
mysqli_stmt_execute($stmt);
?>
Textarea
<div id="about" type="text" name="about" class="content livecomments" contenteditable="true" onpaste="OnPaste_StripFormatting(this, event);"><?php echo $edit ? ( empty( htmlentities ($row[ 'about' ]) ) ) ? 'test' : htmlentities ($row[ 'about' ]) : '';?></div>
The problem is here
var about = $('#about').val().trim();
<div> elements doesnot have value. You should use html() or text()
var about = $('#about').text().trim();

I am trying to refresh my a page if there is a change in orderStatus from database using Ajax and PHP. I set the current orderStatus as predefined data and then use Ajax to get the current orderStatus from database and finally compare if they are not the same. I want to refresh the page if they are not the same.
PHP (autorefresh.php)
<?php
$orderId = $_POST["orderId"];
$query = "SELECT * FROM orderinhomeonlinecall WHERE orderId='$orderId'";
$result = mysqli_query($db, $query);
while($row = mysqli_fetch_array($result))
{
$orderStatus = $row['orderStatus'];
$data = array(
'orderStatus' => $orderStatus
);
echo json_encode($data);
}
?>
Javascript
<script type="text/javascript" >
var predefined_val = '<?php echo $orderStatus; ?>';// your predefined value.
$.document(ready(function(){
setInterval(function(){
$.ajax({
type:"POST",
url:"autorefresh.php", //put relative url here, script which will return php
data:{orderId: <?php echo $orderId; ?>}, // if any you would like to post any data
success:function(response){
var data = response; // response data from your php script
if(predefined_val !== data){
window.location.href=window.location.href;
}
}
});
},5000);// function will run every 5 seconds
}));
The below code should work, Need to mention dataType:"json" else use JSON.stringify(data) to parse response
<script type="text/javascript">
var predefined_val = '<?php echo $orderStatus; ?>';// your predefined value.
$(document).ready(function () {
setInterval(function () {
$.ajax({
type: "POST",
url: "autorefresh.php", //put relative url here, script which will return php
data: {orderId: <?php echo $orderId; ?>}, // if any you would like to post any data
dataType: "json",
success: function (response) {
var data = response; // response data from your php script
if (predefined_val !== data.orderStatus) {
window.location.href = window.location.href;
}
}
});
}, 5000);// function will run every 5 seconds
});
</script>
I have tested this by creating two files(autorefresh.php,index.php) and test db with table and it is working for me. I think the below code would be helpful, If not please share you code, i will check and fix it.
autorefresh.php
// Create connection
$db = new mysqli("localhost", "root", "","test");
$orderId = $_POST["orderId"];
$query = "SELECT * FROM orderinhomeonlinecall WHERE orderId='$orderId'";
$result = mysqli_query($db, $query);
while($row = mysqli_fetch_array($result))
{
$orderStatus = $row['orderStatus'];
$data = array(
'orderStatus' => $orderStatus
);
echo json_encode($data);
}
?>
index.php
<?php
$orderStatus ='pending';
$orderId =1;
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
var predefined_val = '<?php echo $orderStatus; ?>';// your predefined value.
$(document).ready(function () {
setInterval(function () {
$.ajax({
type: "POST",
url: "autorefresh.php", //put relative url here, script which will return php
data: {orderId: <?php echo $orderId; ?>}, // if any you would like to post any data
dataType: "json",
success: function (response) {
var data = response; // response data from your php script
if (predefined_val !== data.orderStatus) {
window.location.href = window.location.href;
}
}
});
}, 5000);// function will run every 5 seconds
});
</script>
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();
Recently i developed a load more functionality using php and jquery . Please see my code
Html
<div class="container clearfix product-output">
</div>
jQuery
$.ajax({
method: "POST",
url: "result.php",
data: { keyword:"all"}
}).done(function( msg ) {
$( ".product-output" ).html(msg);
$(".load-more").on("click",function(){
var load_num= $('.load-more').length;
var appear=[];
$(".im-product-block").each(function(){
appear.push($(this).attr('id'));
});
$.ajax({
method: "POST",
url: "result.php",
data: { keyword: "all", y_id: appear, load_num: load_num }
}).done(function(msg1){
$('.load-more-div').before(msg1);
if($(".hide-load").val()==1){
$(".load-more").hide();
}
});
});
});
In result .php i write the db connection code and following query .
$query = 'SELECT * FROM `product` ORDER BY id DESC LIMIT 15';
$query_1 = 'SELECT * FROM `product` ORDER BY id DESC';
if (ISSET($_POST['y_id'])) {
$appear = implode("', '", $_POST['y_id']);
$query = "SELECT * FROM `product` WHERE id NOT IN('{$appear}') ORDER BY id DESC LIMIT 15";
$query_1 = "SELECT * FROM `product` WHERE id NOT IN('{$appear}') ORDER BY id DESC";
}
$result = $conn->query($query);
$result_1 = $conn->query($query_1);
$total_num = $result_1->num_rows;
echo '<div class="container clearfix product-output">';
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) { ?>
<div class="col-sm-2 im-product-block" id="<?php echo $row["id"]; ?>">
<p class="product-name"> <?php echo $row["name"]; ?></p></div>
<?php }
echo '</div>';
if ($total_num > 15 && $_POST[load_num] == 0) {
echo '<div class="load-more-div"><p class="load-more"> Load More</p></div>';
}
if ($total_num < 15) {
echo '<input type="hidden" name="hide-load" class="hide-load" value="1">
<div class="load-finished"><p class="load-f"> All Products Loaded Successfully</p></div>';
}
}
Here all this functionality is working fine . But instead of clicking load more button , when user scroll down to load-more it need to fetch the products automatically without clicking .
for that i using the following code
$(window).scroll(function() {
var hT = $(".load-more").offset().top,
hH = $(".load-more").outerHeight(),
wH = $(window).height(),
wS = $(this).scrollTop();
if (wS > (hT+hH-wH)){
$(".load-more").trigger("click");
}
});
But here the execution is contunied to infinity .It is not stopping . Please check this code and suggest a good method
I think you need to stop your load executing while your ajax call is made and written to the page. Perhaps set a boolean variable to decide if you need to load more.
e.g.
var canLoad = true;
$(window).scroll(function() {
var hT = $(".load-more").offset().top,
hH = $(".load-more").outerHeight(),
wH = $(window).height(),
wS = $(this).scrollTop();
if (wS > (hT+hH-wH) && canLoad){
canLoad = false;
$(".load-more").trigger("click");
}
});
Set canLoad back to true once your ajax function has finished and you have loaded the data.
I have a small script that runs a php file in the background and gets a variable every 3 seconds and put it in a div
script in document with div
<script>
$(document).ready(function() {
setInterval(function () {
$('#statmoney').load('safe.php');
}, 3000);
});
</script>
PHP FILE (safe.php)
$sql = "SELECT * FROM users WHERE id='".$_SESSION['user_id']."'";
$query = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_object($query);
$money = htmlspecialchars($row->money);
echo $money;
If i need to add another variable i would need to make a new document is there a easy way to go about it?
UPDATE
menu.php
<script>
$(document).ready(function() {
setInterval(function () {
var fields = ['money', 'ore', 'energy']; // array of needed fields
$.ajax({
type: "POST",
url: "menusafe.php",
data: {'fields': fields},
dataType: 'json',
success: function(response) {
// assuming that we already have divs for respective fields
fields.forEach(function(v){
console.log(response)
$("#" + v).html(response[v]);
});
}
});
}, 3000);
});
</script>
<div class="menustats"><img src="graphics/logos/moneylogo.png" class="menustatimage"><div class="menustattext" id='money'></div></div>
<div class="menustats"><img src="graphics/logos/energylogo.png" class="menustatimage"><div class="menustattext" id="energy"></div></div>
<div class="menustats"><img src="graphics/logos/orelogo.png" class="menustatimage"><div class="menustattext" id='ore'></div></div>
PHP(menusafe.php)
<?php
if ( isset($_POST['fields']) && !empty($_POST['fields']) && is_array($_POST['fields']) ){
$fields = $_POST['fields'];
$fields = (count($fields) > 1)? implode(',', $fields) : $fields;
$sql = "SELECT $fields FROM users WHERE id='".$_SESSION['user_id']."'";
$query = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_object($query);
$result = [];
foreach($fields as $field){
$result[$field] = $row->{$field};
}
echo json_encode($result);
}
?>
Let's imagine that we want to retrieve three fields from users table : firstname, age and money. In such case it would be better to use $.post or $.ajax method:
js part:
<script>
$(document).ready(function() {
setInterval(function () {
var fields = ['firstname', 'age', 'money']; // array of needed fields
$.ajax({
type: "POST",
url: "safe.php",
data: {'fields': fields},
dataType: 'json',
success: function(response) {
// assuming that we already have divs for respective fields
fields.forEach(function(v){
$("#" + v).html(response[v]);
});
}
});
}, 3000);
});
</script>
php part: (safe.php)
if ( isset($_POST['fields']) && !empty($_POST['fields']) && is_array($_POST['fields']) ){
$fields = $_POST['fields'];
$fields = (count($fields) > 1)? implode(',', $fields) : $fields;
$sql = "SELECT $fields FROM users WHERE id='".$_SESSION['user_id']."'";
$query = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_object($query);
$result = [];
foreach($fields as $field){
$result[$field] = $row->{$field};
}
echo json_encode($result);
}
I'm trying to create upvote/downvote buttons on a list of articles that I get from a MySql database. The buttons work in the sense that you press on the button and it gets the id of the article. However I can't get the id from article page to the php voting page. When I press the button the database doesn't register the vote. What am I doing wrong?
<script type="text/javascript">
$(function() {
$(".vote").click(function()
{
var id = $(this).attr("id");
var name = $(this).attr("name");
var dataString = 'id='+ id ;
var parent = $(this);
if(name=='up')
{
alert('you upvoted on '+ dataString);
$(this).fadeIn(200);
$.ajax({
type: "POST",
url: "weblectureupvote.php",
data: dataString,
cache: false,
});
}
else
{
alert('you downvoted on '+ dataString);
$(this).fadeIn(200);
$.ajax({
type: "POST",
url: "weblectureupvote.php",
data: dataString,
cache: false,
});
}
return false;
});
});
</script>
This is the php file:
<?php
$pid = $_POST['id'];
try {
$db = new PDO('mysql:host=' . $config['db']['host'] . ';dbname=' . $config['db']['dbname'], $config['db']['username'], $config['db']['password']);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$result=mysql_query("SELECT * FROM database WHERE pid = '$pid' ") or die(mysql_error());
while ($row = mysql_fetch_array($result)) {
// temp user array
$lecturelist = array();
$lecturelist["pid"] = $row["pid"];
$lecturelist["upvote"] = $row["upvote"];
$lecturelist["downvote"] = $row["downvote"];
$lecturelist["vote"] = $row["vote"];
}
$upvote= $row["upvote"];
$downvote = $row["downvote"];
$vote = $row["vote"];
$upvote = $upvote + 1;
$query = $db->prepare('UPDATE database SET upvote = :upvote WHERE pid = :pid');
$query->execute(array(
':upvote' => $upvote,
':pid' => $pid
));
$query = $db->prepare('UPDATE database SET vote=:vote WHERE pid = :pid');
$query->execute(array(
':vote' => $vote,
':pid' => $pid
));
} catch(PDOException $e) {
echo $e->getMessage();
}
?>
data: {id: id}
this will get to your php file a "id" variable ( this is the first id ) and with some value ( from the second id )
now
$pid = $_POST['id'];
this should work, as you weren't sending "much" to the server
