How to code so php forces mysql to show only the final row of the column ?
The followings are how I coded (2 copied youtube tuts) to show all rows to allow user to delete multiple rows:
SAMPLE 1
[php]
<?php
session_start();
require "conn.php";
require "site_details.php"; ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Follow Users</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form name="form" action="" method="post"> <table border=1 cellpadding=1 cellspacing=1> <tr> <th>Id</th> <th>Username</th> <th>Password</th> <th>Email</th> <th>Delete</th> </tr> <?php
$res=mysqli_query($conn,"SELECT * FROM users");
while($row=mysqli_fetch_array($res))
{
echo "<tr>";
echo "<td>"; ?> <input type="checkbox" name="num[]" class="other" value="<?php echo $row["id"]; ?>" /> <?php echo "</td>";
echo "<td>"; echo $row["ids"]; echo "</td>";
echo "<td>"; echo $row["usernames"]; echo "</td>";
echo "<td>"; echo $row["passwords"]; echo "</td>";
echo "<td>"; echo $row["emails"]; echo "</td>";
echo "</tr>";
}
?> </table> <input type="submit" name="submit" value="delete selected"> </form> <?php
if(isset($_POST["submit"]))
{
$box=$_POST['num'];
while (list ($key,$val) = @each ($box))
{
mysqli_query($conn,"DELETE FROM users WHERE id='$val'");
}
?> <script type="text/javascript">
window.location.href=window.location.href;
</script> <?php
}
?> </body> </html>
[/php]SAMPLE 2:
[php]
<?php
session_start();
require "conn.php";
require "site_details.php"; ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Follow Users</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form name="form" action="" method="post"> <table border=1 cellpadding=1 cellspacing=1> <tr> <th>Id</th> <th>Username</th> <th>Password</th> <th>Email</th> <th>Delete</th> </tr> <?php
$res=mysqli_query($conn,"SELECT * FROM users");
while($row=mysqli_fetch_array($res))
{
echo "<tr>";
echo "<td>"; ?> <input type="checkbox" name="num[]" class="other" value="<?php echo $row["id"]; ?>" /> <?php echo "</td>";
echo "<td>"; echo $row["ids"]; echo "</td>";
echo "<td>"; echo $row["usernames"]; echo "</td>";
echo "<td>"; echo $row["passwords"]; echo "</td>";
echo "<td>"; echo $row["emails"]; echo "</td>";
echo "</tr>";
}
?> </table> <input type="submit" name="submit" value="delete selected"> </form> <?php
if(isset($_POST["submit"]))
{
$box=$_POST['num'];
while (list ($key,$val) = @each ($box))
{
mysqli_query($conn,"DELETE FROM users WHERE id='$val'");
}
?> <script type="text/javascript">
window.location.href=window.location.href;
</script> <?php
}
?> </body> </html>
[/php]
