Nested DataTables with non-AJAX data source - javascript

I got the following code with bootstrap collapse, but I need a sorting option. Because of this issue I would like to solve my problem with a DataTables. Is there an option to solve my problem without using ajax? I want to fill the parent table and the child by a sql query.
Like this example
<?php
$switches = $pdo->prepare("Select d.name AS 'Hostname', GROUP_CONCAT(DISTINCT v.id ORDER BY v.id ASC SEPARATOR ' / ') AS 'VLAN', GROUP_CONCAT(DISTINCT v.name ORDER BY v.name ASC SEPARATOR ' / ') AS 'Location'
FROM device d
INNER JOIN vlan v ON d.deviceId = v.deviceId
GROUP BY d.name");
$result = $switches->execute();
$count = 0;
while ($row = $switches->fetch()) {
echo '<tr class="accordion-toggle">';
echo '<td><button class="btn btn-default btn-xs collapsed" data-toggle="collapse" data-target="#' . ++$count . '"></button></td>';
echo "<td>" . $row['Hostname'] . "</td>";
echo "<td><a>" . $row['VLAN'] . "</a></td>";
echo "<td>" . $row['Location'] . "</td>";
echo '<td>
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</td>';
echo "</tr>";
echo "<tr>";
echo '<td colspan="12" class="hiddenRow"><div class="accordian-body collapse" id=' . $count . '>';
echo '<table class="table table-striped">';
echo "<thead>";
echo '<tr><p>Interface IP</p>';
echo "</tr>";
echo "<tr>";
echo "<th>Hostname</th>";
echo "<th>phys. Port</th>";
echo "<th>Port Type</th>";
echo "<th>VLAN</th>";
echo "<th>Destination Hostname</th>";
echo "<th>Destination Port</th>";
echo "<th>Tagged</th>
</tr>";
echo "</thead>";
echo "<tbody>";
$statement = $pdo->prepare("SELECT a.physikalischerPort as 'phys. Port', a.logischerPort as 'log. Port', pt.type as 'Port Type', GROUP_CONCAT(v.id ORDER BY v.id ASC SEPARATOR ' / ') as VLAN, d2.name as 'Destination Hostname', b.physikalischerPort as 'Destination Port', pt.tagged as 'Tagged'
FROM port a
inner JOIN port b ON a.portId = b.destinationPortId
INNER JOIN device d ON d.deviceId = a.deviceId
INNER JOIN device d2 ON d2.deviceId = b.deviceId
INNER JOIN porttype pt ON pt.porttypeId = a.porttypeId
INNER JOIN vlan v ON v.portId = a.portId
WHERE a.portId = b.destinationPortId AND b.portId = a.destinationPortId AND a.deviceId = '" . $count . "'
GROUP BY a.logischerPort, a.physikalischerPort,d2.name, b.physikalischerPort, pt.type, pt.tagged
ORDER BY (a.physikalischerPort +0) ASC");
$result = $statement->execute();
while ($row = $statement->fetch()) {
echo "<tr>";
echo "<td>" . $row['phys. Port'] . "</td>";
echo "<td>" . $row['log. Port'] . "</td>";
echo "<td>" . $row['Port Type'] . "</td>";
echo "<td>" . $row['VLAN'] . "</td>";
echo "<td>" . $row['Destination Hostname'] . "</td>";
echo "<td>" . $row['Destination Port'] . "</td>";
echo ($row['Tagged'] == '0') ? '<td><i class="glyphicon glyphicon-remove"></i></td>' : '<td><i class="glyphicon glyphicon-ok"></i></td>';
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
echo "</div>";
echo "</td>";
echo "</tr>";
}
?>

Ajax is not a mandatory source to populate your DataTable, it is only (widely preferred) option that allows you to keep your data up to date without reloading page (e.g. upon editing certain entries or deleting them).
What you need to do is a PHP-script that will echo simple HTML page that has all the necessary prerequisites (including jQuery and DataTables javascripts and stylesheets) referred within <head> section and empty <table id="mytable"></table> within page <body>.
In addition to above prerequisites, you need to refer in your page HTML to dynamically created javascript that uses arrays of objects (obtained from SQL queries) as DataTables source for both parent and child rows:
<?php
/* query your database over here and put the result into associative arrays,
turn them into JSON-compliant arrays/objects */
$parentSource = ... //PHP variable that contains JSON for parent rows
$childSource = ... //PHP variable that contains JSON for child rows
$js = <<<JS
$(document).ready(function () {
const parentData = ${$parentSource};
const childData = ${$childSource};
const dataTable = $('#mytable').DataTable({
sDom: 't',
data: parentData,
columns: [
{title: 'Hostname', data: 'hostname'},
{title: 'VLAN', data: 'vlan'},
{title: 'Location', data: 'location'},
],
});
//prepare child DataTable upon clicking parent row
$('#mytable').on('click', 'tr', function(){
const parentRow = dataTable.row($(this));
parentRow.child.isShown() ?
parentRow.child.remove() :
parentRow.child('<table id="details"></table>').show();
$(this).toggleClass('shown');
if(!parentRow.child.isShown()) return;
const detailsData = childData[parentRow.data().hostname];
$('#details').DataTable({
sDom: 't',
data: detailsData,
columns: [
{title: 'Hostname', data: 'hostname'},
{title: 'Port', data: 'port'},
{title: 'Port type', data: 'porttype'},
{title: 'VLAN', data: 'vlan'},
{title: 'Destination host', data: 'dsthost'},
{title: 'Destination port', data: 'dstport'},
]
});
});
});
JS;
/* here should go the code to insert above JS code as a <script>
into your page */
?>
Hopefully, I've made my point clear despite of possible PHP blunders (since I haven't been using PHP for a while).

Updating mySQL table with user interface - PHP

[Sample Look]
I'm trying to make an interface where you can edit/add/remove fields of a mySQL database. This is how it looks visually, and I have all the functionality on the client side working.
My question is: How can I pass any edits/adds/removals to the server side? I'll include a link for my JSFiddle.
And the code below will show how I currently great the table.
<?php
$servername = "localhost";
$username = "lalalal";
$password = "lalalal";
$link = mysqli_connect("localhost", "lalala", "lalala", "lalala");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$sqlStart = "SELECT `Name`, `EXT`, `Returning Time`, `Returning Date`, `Out`, `Reset`, `Booked` FROM `lalala`";
if($result = mysqli_query($link, $sqlStart)){
if(mysqli_num_rows($result) > 0){
echo "<table id = contactTable>";
echo "<tr id = row1>";
echo "<th id = sortTable onclick=sortTable(0)>Name ↕</th>";
echo "<th style = width:100px;>EXT</th>";
echo "<th style = width:300px;>Returning Time</th>";
echo "<th style = width:300px;>Returning Date</th>";
echo "<th style = width:70px;>Out</th>";
echo "<th style = width:100px;>Reset</th>";
echo "<th style = width:600px;>Booked</th>";
echo "</tr>";
while($row = mysqli_fetch_array($result)){
$currentCheck = $row['Out'];
if ($currentCheck == 0) {
echo "<tr>";
echo "<td>" . $row['Name'] . "</td>";
echo "<td>" . $row['EXT'] . "</td>";
$currentTime = $row['Returning Time'];
if ($currentTime == 0) {
echo "<td> <form> <input type = 'time', id = 'timePickChange'> </form> </td>";
} else {
echo "<td> <form> <input type = 'time', id = 'timePickChange' value =" . $currentTime . "> </form> </td>";
}
$currentDate = $row['Returning Date'];
echo "<td> <form> <input type = 'date', id = 'datePickChange' value =" . $currentDate . "> </form> </td>";
echo "<td> <form onclick = 'checkIfOutRow(this)'> <input type = 'checkbox', onclick = 'checkIfOutValue(this)'> </form> </td>";
echo "<td> <button onclick = 'clearForm(this)', id = buttonClear>Reset</button> </td>";
echo "<td> <textarea rows = '1', cols = '60'> </textarea> </td>";
} else if ($currentCheck == 1) {
echo "<tr style = 'background-color: #E2E9FD'>";
echo "<td>" . $row['Name'] . "</td>";
echo "<td>" . $row['EXT'] . "</td>";
$currentTime = $row['Returning Time'];
echo "<td> <form> <input type = 'time', id = timePickChange disabled> </form> </td>";
$currentDate = $row['Returning Date'];
echo "<td> <form> <input type = 'date', id = datePickChange disabled> </form> </td>";
echo "<td> <form onclick = 'checkIfOutRow(this)'> <input type = 'checkbox', onclick = 'checkIfOutValue(this)' checked> </form> </td>";
echo "<td> <button onclick = 'clearForm(this)', id = buttonClear>Reset</button> </td>";
echo "<td> <textarea rows = '1', cols = '60'> </textarea> </td>";
}
echo "</tr>";
}
echo "</table>";
// Free result set
mysqli_free_result($result);
} else{
echo "No records matching your query were found.";
}
} else{
echo "ERROR: Could not able to execute $sqlStart. " . mysqli_error($link);
}
?>
Depending on your data validation model, you might want to control the inputs value client side before posting them to your back-end.
AFAIK, you're already adding/editing/removing your contacts on the client side, so If I understand correctly, when your user should click on Edit/Remove & confirm , it would be a confirmation of what the user has done in the browser, this doesn't really change much apart from the fact that otherwise you might need dedicated buttons/row (or any other bindable events).
For these operations what you could do is proceed to bulk delete / edit, and this could be easily done by filtering out in your JS all the modified/deleted data and sending it to your back end PHP with Ajax/jQuery in the form of a stringified array.
As for insertion operation you'd submit them at the same time you add them to your table, by executing a POST operation.
And it could be done with something like this :
$.ajax({
method: "PUT",
url: "some.php",
data: JSON.stringify(myUpdatedDataInAnArray)
// you might need to stringify your array to ensure format ?
})
.done(function( msg ) {
alert( "Data Updated: " + msg );
});
In your back end php, you'd listen for POST/PUT/DELETE methods with something like that :
if (isset($_POST['add'])){
do your thing
}
if (isset($_PUT['updated'])){
//Since you're sending a stringified array, you must parse it with
$myArray = json_decode($_PUT['updated']);
do your thing
}
if (isset($_DELETE['deleted'])){
do your thing
}
I say Ajax because using a traditional POST/PUT/DELETE form would result in refreshing the page.

How to send data and run a link with that data with one click

I want to send latitude and longitude data so I can search it up on Google Map. Those data has to be selected from a database but I can't figure how to do it in one click.
Here is my code.
<?php
$con = mysqli_connect("localhost","root","","project");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM table1");
echo "<table border='1'>
<tr>
<th>ID</th>
<th>Latitude</th>
<th>Longitude</th>
<th>Date</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['latitude'] . "</td>";
echo "<td>" . $row['longitude'] . "</td>";
echo "<td>" . $row['date'] . "</td>";
echo "<td><a href='./clicktest.php?id=".$row['id']."'>View Location</a></td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
And as you can see, it sends the id value of a row that I want to another page which is
<?php
$con=mysqli_connect("localhost","root","","project");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(isset($_GET['id'])) {
$result = "SELECT * FROM table1 WHERE id='".$_GET['id']."'" ;
$show = mysqli_query($con, $result);
while($row = mysqli_fetch_array($show))
{
$latitude = $row['latitude'];
$longitude = $row['longitude'];
echo "<a href='http://www.google.com/maps/place/".$latitude.",".$longitude."'>click here</a>";
}
mysqli_close($con);
}
?>
And finally can run a link to Google Map on this page. But what I want is to click on the 'view location' on the first page and jump to the google map page with data on that row without having to go through another page and another click.
I did some research and maybe this is about AJAX? And are there any ways to do it without using AJAX?(since I never use it before)
Thanks
I think you need to directly link to google maps page and use "target=_blank" attribute on it. for example:
echo 'View Location';
You can add as many parameter to the anchor tag as you like, so add the lat and long like this for example
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['latitude'] . "</td>";
echo "<td>" . $row['longitude'] . "</td>";
echo "<td>" . $row['date'] . "</td>";
echo "<td><a href='./clicktest.php?id=".$row['id']
.'&lat=' . $row['latitude']
. '&long' . $row['longitude']"'>View Location</a></td>";
echo "</tr>";
}

Not able to store ajax variables in session array

I am making a cart-mechanism with jquery, ajax and php. The problem is that the text in the html element aren't getting appended to the session array. This is my ajax code:
$(document).ready(function(){
$("#cart").on("click", function(){
var name = $("#name").text();
var cost = $("#cost").text();
$.ajax({
type:"post",
data:"name="+name+"&cost="+cost,
url:"senddata.php",
success:function(data){
$("#info").html(data);
}
});
});
});
This is my html displayed with php:
function getData()
{
require_once('../config.php');
$query = mysqli_query($conn, "SELECT p_name, p_cost, p_pic, p_desc FROM products");
while($row = mysqli_fetch_assoc($query))
{
echo "<form><tr>";
echo "<td id='name' name='name'>" . $row['p_name'] . "</td>";
echo "<td id='cost' cost='cost'>" . $row['p_cost'] . "</td>";
echo "<td>" . $row['p_pic'] . "</td>";
echo "<td>" . $row['p_desc'] . "</td>";
echo "<td id='cart'><input type='button' id='submit' value='Add To Cart'></td><tr></form>";
}
mysqli_close($conn);
}
And finally, this is where I have stored the ajax variables in a session array:
session_start();
$_SESSION['cart_name'] = array();
array_push($_SESSION['cart_name'], $_POST['name']);
var_dump($_SESSION['cart_name']);
$_SESSION['cart_cost'] = array();
array_push($_SESSION['cart_cost'], $_POST['cost']);
var_dump($_SESSION['cart_cost']);
I am getting no error whatsoever but the items get appended to the array the first time, but after that, the variables don't get appended at all.
Variables does not appended because you initialize every time the
$_SESSION['cart_name'] = array();
$_SESSION['cart_cost'] = array();
That means that every time before you push the new data you empty the SESSION var.

Why doesn't 'onclick' work when html is sent through php?

There is a javascript in my page that loads a PHP script into a div every second. This PHP is supposed to run a SQL query that loads data from a database.
Here is an extract of the PHP
while($row = mysqli_fetch_array($result))
{
$starttime = $row['start_time'];
$module = $row['module'];
$item = $row['item'];
echo "<tr>";
echo "<td>" . $row['start_time'] . "</td>";
echo "<td>" . $row['module'] . "</td>";
echo "<td>" . $row['item'] . "</td>";
echo "<td>" . $row['status'] . "</td>";
echo "<td>" . $row['accepted'] . "</td>";
echo "<td>" . $row['end_time'] . "</td>";
echo "<td><button id='btnaccept' onclick='acceptBtn()'>ACCEPT</button></td>";
echo "</tr>";
}
And here is the Javascript
<script>
var auto_refresh = setInterval(
(function () {
$("#dataDisplay").load("updatedb.php"); //Load the content into the div
}), 1000);
</script>
As you can see, the last table data is a button that runs a Javascript function
<script>
function acceptBtn() {
window.alert("Accepted");
}
</script>
But unfortunately, clicking this button won't run the function. Any help would be appreciated
Try set listener:
echo "<td><button id='btnaccept'>ACCEPT</button></td>";
.
$(document).on('click', '#btnaccept', acceptBtn);
function acceptBtn(event) {
event.preventDefault();
window.alert("Accepted");
}

Javascript not working in AJAX response

Below code is the AJAX response to another page. I have added onclick event to table row and written javascript code to handle it. But javascript code doesn't work.Is this wrong way of coding or there is any problem in code. Suggest me a simple solution
<?php
echo '<script type=\"text/javascript\">
function clicked(){
alert("I am an alert box!");
}
</script>';
$q = $_GET['q'];
include 'db_connect.php';
$sql="SELECT name,address,mobile,email,pan,tan FROM client WHERE name = '$q'";
$sql_bill="SELECT clientname,financialyear,receiptno,amount,ddate,type,chequeno,category FROM billing WHERE clientname = '$q'";
$sql_total="SELECT SUM(amount) AS TotalAmount FROM billing";
$result = mysql_query($sql);
$result_bill = mysql_query($sql_bill);
$result_total = mysql_query($sql_total);
$total= mysql_fetch_array($result_total);
echo "<h4><b>Client details</b></h4><table align='center' border='2'>
<tr>
<th>Name</th>
<th>Address</th>
<th>Mobile</th>
<th>Email</th>
<th>PAN</th>
<th>VAT TIN</th>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['address'] . "</td>";
echo "<td>" . $row['mobile'] . "</td>";
echo "<td>" . $row['email'] . "</td>";
echo "<td>" . $row['pan'] . "</td>";
echo "<td>" . $row['tan'] . "</td>";
echo "</tr>";
}
echo "</table>";
echo "<h4><b>Payment received details</b></h4><table align='center' border='2'>
<tr>
<th>Client Name</th>
<th>Financial Year</th>
<th>Receipt No</th>
<th>Date</th>
<th>Type</th>
<th>Chequeno</th>
<th>Category</th>
<th>Amount</th>
</tr>";
while($row = mysql_fetch_array($result_bill))
{
echo "<tr onclick=\"clicked()\">";
echo "<td>" . $row['clientname'] . "</td>";
echo "<td>" . $row['financialyear'] . "</td>";
echo "<td>" . $row['receiptno'] . "</td>";
echo "<td>" . $row['ddate'] . "</td>";
echo "<td>" . $row['type'] . "</td>";
echo "<td>" . $row['chequeno'] . "</td>";
echo "<td>" . $row['category'] . "</td>";
echo "<td>" . $row['amount'] . "</td>";
echo "</tr>";
}
echo "<tr>";
echo "<td colspan=7>Total</td>";
echo "<td>".$total['TotalAmount']. "</td>";
echo "</tr>";
echo "</table>";
?>
Try this instead of your script code:
echo <<<EOD
<script type="text/javascript">
function clicked(){
alert("I am an alert box!");
}
</script>
EOD;
Edit 1:
Look in the console (F12), What happens when you click on a tr?
The following fiddle replicates your code and works:
http://jsfiddle.net/Yaj44/
Edit 2:
I think it has something to do with the way you call the data.
Put the function in your main page,
then call the AJAX.
Set innerHTML of specific div with responseData.
If you do it in that order, it might work.
Your way to adding this functionality is very dirty..
If you use JQuery, you can add on the end:
$('tr').click(function() {
alert('Do something on click!');
});
mysql_fetch_array is outdated, use mysqli (or PDO) instead.
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = $mysqli->query($query)) {
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
/* free result set */
$result->free();
}
/* close connection */
$mysqli->close();
