I need to insert a timestamp into table visitors column out after the user clicks on the sign-out button. The sign-out button already deletes rows in the table liveroster but its not updating rows in table visitors at column out with the timestamp.
mysql_query("UPDATE visitors SET out=test WHERE ID=" . $ID);
<?php
/*
Connection Stuff
*/
if (isset($_POST['ID'])) {
$ID = $_POST['ID'];
if (isset($_POST['delete_id'])) {
mysql_query("UPDATE visitors SET out=test WHERE ID=" . $ID);
mysql_query("DELETE FROM liveroster WHERE ID = " . $ID);
}
}
?>

You could create a column and update it using the "NOW()" function every time you click submit.
UPDATE visitors
SET out = test, getdate = NOW()
WHERE ID = $ID

I'm retrieving all the rows from sql database through a query, and i'm using a loop to get all the rows
I have a style.css file which i'm specifying a style for the , however, only the first row is receiving the style and the style is not being applied to the rest.

It is not a CSS problem, it is because you are closing your </table> in the loop, so it is ending your table after the first tr.
Just remove it from the loop:
<?php
$con = new PDO("mysql:host=localhost;dbname=data",'root','admin123');
if (isset($_POST["submit"])) {
$str = $_POST["search"];
$sth = $con->prepare("SELECT * FROM `questions` WHERE question LIKE '%$str%'");
$sth->setFetchMode(PDO:: FETCH_OBJ);
$sth -> execute();
?>
<table>
<tr>
<th>Project</th>
<th>Question</th>
<th>Sample</th>
</tr>
<?php
for ($a=0;$row = $sth->fetch();$a++) {
?>
<tr>
<td><?php echo $row->Proj_Name; ?></td>
<td><?php echo $row->Question;?></td>
<td><?php echo $row->sample;?></td>
<br><br>

My problem is, when I click the button, all records are changed and not just one. I hope someone can help to solve the problem.
.........................................................................................................................................................................................................
Try using {} to embed array elements into a string and enclose 'id' value
$update = "UPDATE data Set status = '0' WHERE id = {$row['id']}"
Otherwise, your query will interpret $row and [id] as separated items:
UPDATE data Set status = '0' WHERE id = [id]
and as a result, all your rows updated
Also consider to apply the status update button to each single row, there is no way to update only one row with a general "update status" button without sending a parameter of which row id will update. For example:

i want to get the index of td that the user clicked , i have an html table fill from database using php ...
this is my index.php :
<html>
<head>
<title>Last 10 Results</title>
</head>
<body>
<table>
<thead>
</thead>
<tbody>
<tr>
<?php
session_start();
$connect = mysqli_connect("localhost","root","","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = 0");
while($row = mysqli_fetch_assoc($results)) {
?>
<td onclick="window.location='index2.php'"
<?php $id = $row['id'];
$_SESSION['varname'] = $id;?>>
<?php echo $row['name']?> <br/>
<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>
</tr>
</tbody>
</table>
</body>
</html>
this is my index2.php :
<html>
<head>
<title>Last 10 Results</title>
</head>
<body>
<table>
<thead>
</thead>
<tbody>
<tr>
<?php
session_start();
$gg = $_SESSION['varname'];
echo $gg;
$connect = mysqli_connect("localhost","root", "","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = '$gg' ");
while($row = mysqli_fetch_array($results)) {
?>
<td>
<?php echo $row['id']?> <br/>
<?php echo $row['name']?> <br/>
<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>
</tr>
</tbody>
</table>
</body>
</html>
now i want to take the "id" of the td that the user click on,, but this code always give me the last id in my database ...
what can i do ?
Replace in Index.php:
<td onclick="window.location='index2.php'"
With:
<td onclick="window.location='index2.php?parent_id=<?php echo $row['id']; ?>'"
And in
Index2.php:
$gg = $_SESSION['varname'];
With:
$gg = (int)$_GET['parent_id'];
It's better to use $_GET variable for this than $_session (urls are search engine friendly)
I don't get any errors but I can't update MySQL PHP. I want to change dropdown status from "sedang diproses" dropdown into "Berjaya or Tidak Berjaya". Also I can't change in the database "sedang diproses" into "Berjaya or Tidak Berjaya"

Your code is not working because you haven't sent in
<form action="prosesstatus.php" method="post">
Parameters:
$idPemohon = $_GET['idPemohon'];
$idkursus = $_GET['idkursus'];
$idPemohonan =
$_GET['idPemohonan'];
If you want use $_GET link should look like:
prosesstatus.php?idPemohon=value&idkursus=value&idPemohonan=value
Or you should add these parameters in
Input type hidden and change in php to $_POST
I agree with others than you should use MVC for example some kind of framework (Laravel, CodeIgniter)
Or separate as much as possible php and html because your code looks unprofessional.
Your MySQL queries are vulnerable to SQL injection and most likely file
include/connect.php
is not outside public folder which is not good practice to do.
