PHP checkbox only showing first value

I am trying to iterate the row data of each message for each value in the database by a checkbox as when clicked you get the string value on this row
the Code:
<div id="Ticket" style="display:none;" class="tabcontent">
<table class="table">
<thead>
<tr>
<th>Ticket ID </th>
<th>username</th>
<th>Data published</th>
<th>Subject</th>
<th>problem</th>
<th>Statues</th>
<th>Solved?</th>
<th>More Details</th>
</tr>
</thead>
<tbody>
<?php
$query=" Select * FROM tickets where resolved=0";
$result_opened = mysqli_query($db, $query);
while($row = mysqli_fetch_array($result_opened)){ ?>
<tr>
<td data-label="id"><?php echo $row['id']?></td>
<td data-label="username"><?php echo $row['username']?></td>
<td data-label="publish"><?php echo $row['published']?></td>
<td data-label="subject"><?php echo $row['subject']?></td>
<td data-label="problem"><?php echo $row['problem']?></td>
<td data-label="">Open</td>
<td> </i> <br/><br/>
</td>
<td><input type="checkbox" id="toggle">
<label for="toggle">see more</label>
<dialog >
<h>Message</h><br><br>
<p>
//Here I am getting only the first value//
<?php echo $row['message'] ?>
</p>
<label for="toggle">close</label>
</dialog></td></tr>
<?php }?>
</tbody>
</table>
</div>
but I keep on getting only the last value in the specific row
image:
I tried many ways to fix it but the main problem is its only getting the first value in the while loop.

The problem arises because you are assigning same id to all checkbox component.
Instead use this -
input type="checkbox" id="toggle-<?=$row['id']?>">

Auto refresh Table when new row added inside DB

I have a table that is connected to my DB.
I have 4 columns : Date, Time, Windspeed and Wind direction
Since my table gets a new row on average every 10 second or so I wondered if it was possible to dynamically refresh it without refreshing the whole page using AJAX.
I looked examples and tried to adjust it to my case but it just doesn't seems to work
My table looks like this
<table id="table" align="center" border="1px" style="width:600px; line-height:30px">
<tr>
<th colspan="4"><h2> Résultat : <?php echo htmlentities($nom) ?> </h2> </th>
</tr>
<t>
<th> Date </th>
<th> Heure </th>
<th> Vélocité (km/h) </th>
<th> Direction du vent </th>
</t>
<?php
while($rows=mysqli_fetch_assoc($result))
{
?>
<tr>
<td align="center"><?php echo $rows['Date'] ?></td>
<td align="center"><?php echo $rows['Heure'] ?></td>
<td align="center"><?php echo $rows['Velocite'] ?></td>
<td align="center"><?php echo $rows['Direction_vent'] ?></td>
</tr>
<?php
}
?>
</table>
I tried this kind of refresh :
<script>
$(document).ready(function() {
function RefreshTable() {
$( "#table" ).load( "valeurs.php #table" );
}
$("#refresh-btn").on("click", RefreshTable);
});
</script>

Send Table Row Data via AJAX Based on Checkbox Checked

I have a table with multiple columns (index.php). One column is a checkbox. Whenever the checkbox is checked, it displays another column where you can select a quantity.
I want to then be able to hit a button called "Add to Order" and have it use AJAX to add any selected rows to the index-order.php page. After all selections have been made, I want to be able to click the "Checkout" button and have it take me to the index-order.php page where it should display all of the added selections in a table.
I know how to navigate to the index-order.php page so my main question is how can I add the selected rows to the page while using ajax and staying on the current page when doing so?
Index.php code:
<form name="form1" action="index-order.php">
<section id="checkout-btn">
<button type="submit" id="checkout" name="order">Checkout</button>
</section>
</form>
<form name="form2" method="POST" action="index-order.php">
<section id="addToOrder">
<button type="submit" class="order" id="order" name="order" value="AddToOrder">Add to Order</button>
</section>
<br>
<div id="my-div2" class="ui-widget">
<div class="ui-widget">
<table id="merchTable" cellspacing="5" class="sortable">
<thead>
<tr class="ui-widget-header">
<th class="sorttable_nosort"></th>
<th class="sorttable_nosort">Loc</th>
<th class="merchRow">Report Code</th>
<th class="merchRow">SKU</th>
<th class="merchRow">Special ID</th>
<th class="merchRow">Description</th>
<th class="merchRow">Quantity</th>
<th class="sorttable_nosort">Unit</th>
<th style="display: none;" class="num">Quantity #</th>
</tr>
</thead>
<tbody>
<?php foreach ($dbh->query($query) as $row) {?>
<tr>
<td class="ui-widget-content"><input type="checkbox" class="check" name="check"></td>
<td name="rows[0][0][loc]" class="loc ui-widget-content" id="loc-<?php echo intval ($row['Loc'])?>"><?php echo $row['Loc'];?></td>
<td name="rows[0][0][rp-code]" class="rp-code ui-widget-content" align="center" id="rp-code-<?php echo intval ($row['Rp-Code'])?>"><?php echo $row['Rp-Code'];?></td>
<td name="rows[0][0][sku]" class="sku ui-widget-content" id="sku-<?php echo intval ($row['SKU'])?>"><?php echo $row['SKU'];?></td>
<td name="rows[0][0][special-id]" class="special-id ui-widget-content" align="center" id="special-id-<?php echo intval ($row['Special-ID'])?>"><?php echo $row['Special-ID'];?></td>
<td name="rows[0][0][description]" class="description ui-widget-content" id="description-<?php echo intval ($row['Description'])?>"><?php echo $row['Description'];?></td>
<td name="rows[0][0][quantity]" class="quantity ui-widget-content" data-quantity="<?php echo $row['Quantity'] ?>" align="center" id="quantity-<?php echo intval ($row['Quantity'])?>"><?php echo $row['Quantity'];?></td>
<td name="rows[0][0][unit]" class="unit ui-widget-content" id="unit-<?php echo intval ($row['Unit'])?>"><?php echo $row['Unit'];?></td>
<td name="rows[0][0][quant]" style="display: none;" class="quantity_num ui-widget-content"><input type="textbox" style="width: 100px;" class="spinner" name="value" id="test"></td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
</div>
</form>
Index-order.php:
<?php if(isset($_POST['rows'])): ?>
<table cellspacing="20">
<tr align="center">
<th>Loc</th>
<th>Report Code</th>
<th>SKU</th>
<th>Special ID</th>
<th>Description</th>
<th>Quantity</th>
<th>Unit</th>
<th>Quantity #</th>
</tr>
<?php
foreach($_POST['rows'][0] as $row):
?>
<tr align="center">
<td><?php echo $row['loc']; ?></td>
<td><?php echo $row['rp-code']; ?></td>
<td><?php echo $row['sku']; ?></td>
<td><?php echo $row['special-id']; ?></td>
<td><?php echo $row['description']; ?></td>
<td><?php echo $row['quantity']; ?></td>
<td><?php echo $row['unit']; ?></td>
<td><?php echo $row['quant']; ?></td>
</tr>
<?php
endforeach;
?>
</table>
<?php endif; ?>
JavaScript (obviously needs some work. Posting what I have so far):
$(function () {
$('#form2').on('submit', function (e) {
if($('input.check').is(':checked')) {
$(this).closest('tr');
e.preventDefault();
var request = $.ajax({
type: 'post',
url: 'index-order.php',
data: $('#form2').serialize(),
success: function(){
alert('success');
},
error: function(){
alert('failure');
}
});
}
});
});

What you can do is get all the siblings of the current checked checkbox and based on that get all the columns and separate the data to finally send it via ajax.
You can do something like this:
$('#form2').on('submit', function (e) {
$checkbox = $(this).find('input.check:checked').parent('td'); //Finds the checked checkbox's column inside #form2
$otherColumns = $checkbox.nextAll(); //Gets all the siblings
});
The above code will get you all the other columns next to the checked checkbox inside your form. What you an do next is travel across $otherColumns and get each individual value using $otherColums.eq(n).html() where n is the number of the column you are trying to get.

How to get the id of the last element?

I have the list of products ,using below code
<table id="product">
<thead>
<tr>
<th style="width:30%;">Item Name</th>
<th style="width:11%;">Price</th>
<th style="width:11%;">Qty</th>
</tr>
</thead>
<tbody id="cart_contents">
<?php $i=1;
foreach($cart as $line=>$item)
{
?>
<tr>
<td style="align:center;"><?php echo $item['name']; ?></td>
<td><input type="text" id="price_<?php echo $i;?>" value="<?php echo $item['price']; ?>" name="price"></td>
<td id="qnty"><input type="text" id="quantity_<?php echo $i;?>" value="<?php echo $item['quantity']; ?>" name="quantity"></td>
</tr>
<?php
$i++;
}
?>
</tbody>
</table>
I need to edit quantity and price fields of last added product.
<table width="297px" style="float:left" class="CSSTableGenerator">
<tr>
<td onclick="click_quantity();">Qty</td>
<td onclick="click_price();"> <a href="javascript:void(0);" >Price</a></td>
</tr>
</table>
function click_quantity(){
$("#table register").find("td qnty").each(function(){
var id = $(this).attr("id");
alert(id);
})
}
How to get the last quantity field's id, after clicking the Qty link?
I have tried some codes, but I am unable to get last element's id.
EX : id names are quantity_1, quantity_2, quantity_3, quantity_4.
How to get quantity_4 (last elment's id)?

HTML
<table id="product">
<thead>
<tr>
<th style="width:30%;">Item Name</th>
<th style="width:11%;">Price</th>
<th style="width:11%;">Qty</th>
</tr>
</thead>
<tbody id="cart_contents">
<?php $i=1;
foreach($cart as $line=>$item)
{
?>
<tr>
<td style="align:center;"><?php echo $item['name']; ?></td>
<td>
<input type="text" id="price_<?php echo $i;?>" value="<?php echo $item['price']; ?>" name="price"/>
</td>
<td class="qnty">
<input class="qnty_input" type="text" id="quantity_<?php echo $i;?>" value="<?php echo $item['quantity']; ?>" name="quantity"/>
</td>
</tr>
<?php
$i++;
} ?>
</tbody>
</table>
JS Code
function click_quantity(){
var id = $("#cart_contents tr:last-child .qnty_input").attr("id");
// rest of your logic
}

1) you are using same ID in loop, that is not valid;
2) I think your js is wrong, use : $("#register").find("#qnty"), but has to be find('.qnty')

Try this one.
var last_id = $( 'table tbody tr td:last-child').attr( 'id' );

To get the last row(td) in table you can use this,
$('table tbody tr td:last-child')

In order to get last child element you can make use of Try to use last property of jquery
$("#cart_contents td:last").find('input[type=text]').attr('id');

$("#cart_contents td:last")
using this you'll find last column in each row so you have to use
$("#cart_contents tr:last-child td.qnty")

Update MySQL data from HTML using Javascript

I'm a beginner in HTML, PHP, JavaScript and MySQL. I've written a HTML code to enter data into a simple table containing columns "Name" and "Email" in MySQL by employing a seperate PHP file. Then I tried fetching the table contents using PHP. But now I need a little help in updating the data. My code is as follows:
enter code here<!DOCTYPE html>
<html>
<script language="javascript" src="update.js"></script>
<?php
$a=mysqli_connect("localhost","root","","test4");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($a,"select * FROM test");
?>
<table border="1" cellspacing="1" cellpadding"1">
<tr>
<th>pkid</th>
<th>Name</th>
<th>Email</th>
<th>Action</th>
</tr>
<?php
for ($i=0; $i<mysqli_num_rows($result); $i++)
{
$row = mysqli_fetch_array($result)
?>
<tr>
<td id="pkid"><?php echo $row['pkid'] ?></td>
<td id="name"><?php echo $row['name'] ?></td>
<td id="email"><?php echo $row['email'] ?></td>
<td><input type=submit onclick="myfunc()" value="View"/></td>
</tr>
<?php
}
?>
</table>
<form action="insert.php" method="post">
<table border="2">
<tr>
<td>Name</td>
<td><input type="text" name="name"></td>
</tr>
<tr>
<td>Email</td>
<td><input type="text" name="email"></td>
</tr>
<tr>
<td>
<input type="submit" value="Add">
</tr>
</table>
</form>
</html>
<?php
mysqli_close($a);
?>

Here is the Code for Update Data to MYSQL :
Html File :
<title>Listing Details for Update</title>
<?php
include ('config.php');
$tbl_name="user"; // Table name
$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql </strong> </td>
<td></td>
<td></td>
</tr>
<tr>
<td align="center"><strong>pkid</strong></td>
<td align="center"><strong>Name</strong></td>
<td align="center"><strong>Email-Id</strong></td>
<td align="center"><strong>Action</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td><? echo $rows['pkid']; ?></td>
<td><? echo $rows['name']; ?></td>
<td><? echo $rows['email']; ?></td>
<td align="center">update</td>
</tr>
<?php
}
?>
</table>
</td>
</tr>
</table>
<?php
mysql_close();
?>
Here you can find the way for Update Single Field, Multiple Field Etc.,

If you need to change the contents of the table to have different rows/row data, (and you want to do it live) you will need to use AJAX. jQuery has fairly straightforward ajax usage, so for actual implementation, I would look to that. You'll also need another PHP file that just returns the raw HTML required to fill in the table. Pseudocode (jquery) below:
$.post("url","dataToPost",function(data){$("#table id where I want to put new data).innerHTML=data});
Basically, the $.post() posts the dataToPost to the url and sets the innerHTML of whatever you select to the resultant data.
