Any assistance with this would be greatly appreciated. If I am still unclear, please ask for further clarification.
just seeing your last include will also result in an error, you will need to end with ;

In my admin page, admin can view the user id, user name and email id. Now, the admin can click user name, then it displays the details of that particular user name. I don't know how to do. Please help. My code is given below.
<html>
<head>
<title>Admin Page</title>
</head>
<body>
Welcome
<?php
include ('connect.php');
session_start();
$admin = $_SESSION['adminname'];
echo "$admin";?>
<b> SIGN OUT</b>
<table border="2" align="center">
<thead>
<tr>
<th>User_id</th>
<th>User Name</th>
<th>Email ID</th>
</tr>
</thead>
<tbody>
<?php
$query = mysqli_query($con, "SELECT * FROM sample");
while($row = mysqli_fetch_array($query))
{
$id=$row[0];
$name=$row[1];
$mail=$row[2];
echo
"<tr>
<td>{$row[0]}</td>
<td>{$row[1]}</td>
<td>{$row[2]}</td>";
}?>
</tbody>
</table>
</body>
</html>
First you query your database to get all username,ID and email.
Then you do a loop to display it.
Key is in your loop you can do like this.
<?php
$query = mysqli_query($con, "SELECT * FROM sample");
while($row = mysqli_fetch_array($query)){
$id=$row[0];
$name=$row[1];
$mail=$row[2];
echo "<tr>";
echo "<td>";
echo "<a href='?userid=$id'>$id</a>";
echo "</td>"
echo "<td>";
echo "<a href='?userid=$id'>$name</a>";
echo "</td>"
echo "<td>";
echo "<a href='?userid=$id'>$email</a>";
echo "</td>"
echo "</tr>";
}
?>
This is result from loop above.
<tr>
<td>
<a href='detail.php?userid=1'>Fullname1 : Email1#email.com</a>
<a href='detail.php?userid=2'>Fullname2 : Email2#email.com</a>
...
</td>
</tr>
Now you will see this in your URL ?userid=1
You can do this on top of detail.php file $user_id = $_GET['userid'];
Then you get your user_id // 1 2 3 4 5 ... whatever
Now you do a query again with $user_id
like this :
$query = "SELECT * FROM sample WHERE user_id = $user_id";
while($row = mysqli_fetch_array($query)){
//do what you want with this user data
}
I here modified your code, Please try this,
<html>
<head>
<title>Admin Page</title>
</head>
<body>
Welcome
<?php
include ('connect.php');
session_start();
$admin = $_SESSION['adminname'];
echo "$admin";
?>
<b> SIGN OUT</b>
<table border="2" align="center">
<thead>
<tr>
<th>User_id</th>
<th>User Name</th>
<th>Email ID</th>
</tr>
</thead>
<tbody>
<?php
$query = mysqli_query($con, "SELECT * FROM sample");
while($row = mysqli_fetch_array($query))
{
$id=$row[0];
$name=$row[1];
$mail=$row[2];
echo '<tr>';
echo '<td>{$row[0]}</td>';
echo '<td>{$row[1]}</td>';
echo '<td>{$row[2]}</td>';
echo '</tr>';
}
?>
</tbody>
</table>
</body>
</html>
Hope it will solve your issue.
I have an issue with the below code, it is showing the html part but not the data from my database. I am just trying to have the data from the database in the drop down list and when I click find to display it on the table below. Can you please help?
<?php
include 'config.php';
?>
<html>
<head>
<meta charset="UTF-8">

<body>
<select name="manufacturer">
<option value="">----ALL----</option>
<?php
$sql = "SELECT id, manufacturer FROM coop";
$result = $conn->query($sql);
while ($r = mysqli_fetch_assoc($result))
{
echo "<option value='$r[id]'> $r[manufacturer]</option>";
}
?>
</select>
<input type="submit" name="find" value="find"/>
<br><br>
<table border="1">
<tr align="center">
<th>ID</th> <th>Manufacturer</th>
</tr>
<?php
if($_SERVER['REQUEST_METHOD'] == "POST")
{
$des=$_POST["manufacturer"];
if($des=="")
{
$result= mysqli_query("SELECT id, manufacturer FROM coop");
}
else
{
$result= mysqli_query($sql);
}
echo "<tr><td colspan='5'></td></tr>";
while($r= mysqli_fetch_assoc($result))
{
echo "<tr>";
echo "<td align='center'>$r[0]</td>";
echo "<td width='200'>$r[1]" . " $r[2]</td>";
echo "<td alig='center' width='40'> $r[3]</td>";
echo "<td align='center' width='200'>$r[4]</td>";
echo "<td width='100' align='center'>$r[5]</td>";
echo "</tr>";
}
}
?>
</table>
</body>
</html>
your queries are wrong here
<?php
$sql = "SELECT id, manufacturer FROM coop";
$result = $conn->query($sql);
while ($r = mysqli_fetch_assoc($sql))
{
echo "<option value='$r[0]'> $r[0]</option>";
}
?>
this while ($r = mysqli_fetch_assoc($sql)) should be while ($r = mysqli_fetch_assoc($result ))
you should fetch your assoc with $result not with$sql
still you have some error bellow part

I needed to use

I am using php / mysql and protype.js to delete record from a table. problem is that after deleting record from grid, grid is not updating automatically in template.
This is my code:
Step 1: index.php
<?php
require("Connection.php");
$sql = "SELECT * from tbluser";
$result=mysql_query($sql);
?>
<html>
<head>
<script src="prototype.js" type="text/javascript"></script>
<script src="scriptaculous-js/src/scriptaculous.js" type="text/javascript"></script>
<script language="javascript">
function fnDeleteRecord(id)
{
new Ajax.Request('delete.php?action=Delete&id='+id,{method:'get'});
}
</script>
</head>
<body>
<table id="userrecords" border="1" cellpadding="0" cellspacing="0" width="700">
<tr>
<th> User Name </th>
<th> Password </th>
<th> Address </th>
<th> Phone Number </th>
<th> Action </th>
<th> Status </th>
</tr>
<?php
while($row = mysql_fetch_array($result))
{
echo "<tr id='".$row[id]."'>";
echo "<td>".$row['user_name']."</td>";
echo "<td>".$row['pass']."</td>";
echo "<td>".$row['address']."</td>";
echo "<td>".$row['phone_no']."</td>";
echo "<td><img src='images/spinner.gif' id='a[$row[id]]' alt=icon border=0 /><a href='javascript:void(0);' onclick=fnDeleteRecord('".$row['id']."'); >Delete</a></td>";
if($row['status'] == 'enabled')
echo "<td><img src='images/spinner.gif' id='a[$row[id]]' alt=icon border=0 style='display:none;' /><img src='images/enable.png' alt=icon border=0 onClick=fnUpdateStatus('".$row['id']."','disabled') /></td>";
else if ($row['status'] == 'disabled')
echo "<td><img src='images/spinner.gif' id='a[$row[id]]' alt=icon border=0 style='display:none;' /><img src='images/disable.png' alt=icon border=0 onClick=fnUpdateStatus('".$row['id']."','enabled') /></td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
</body>
</html>
Step 2: delete.php
<?php
require_once('connection.php');
if ($_GET['action'])
{
switch($_GET['action'])
{
case 'Delete':
$sql = "Delete from tbluser where id ='".$_GET['id']."'";
$result = mysql_query($sql);
if(!$result)
echo "some problem occured during delete operation";
break;
}
}
?>
You can remove that table row with prototype:
<script language="javascript">
function fnDeleteRecord(id)
{
new Ajax.Request('delete.php?action=Delete&id='+id,{method:'get'});
$(id).remove(); // because <tr id='".$row[id]."'> :)
}
</script>
