i would like a button to delete the table entry next to it. But I am coming up short. I seem to be typing something wrong here is my attempt:
<td><a href="delete-quote.php?id=<?php echo $row['id'];?>"><button class="btn-danger-dark">Delete</button></a></td>
but it doesn't seem to work. I only get the ELSE error message
I have tried small changes but with no affect. Im pretty sure its something small that I am missing.
my delete-quote.php code:
<?php
$id = $_GET['id'];
//Connect DB
// on success delete : redirect the page to original page
$dbname = "siyakhat_ibroker";
$conn = mysqli_connect("localhost", "siyakhat_root", "*****", $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// sql to delete a record
$sql = "DELETE FROM prerequest WHERE id = $id";
if (mysqli_query($conn, $sql)) {
mysqli_close($conn);
header('Location: manage-quotes.php');
exit;
} else {
echo "Error deleting record";
}
?>
UPDATE
my dbconnect.php
<?php
$mysql_hostname ="localhost";
$mysql_user ="siyakhat_root";
$mysql_password ="****";
$mysql_database ="siyakhat_ibroker";
$prefix = "";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
?>
did you tried creating a db connection?
dbCon.php
define('HOST','localhost');
define('USER','root');
define('PASS','your_pass_here');
define('DB','siyakhat_ibroker');
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect to the DB');
then your delete-quote.php should looks like:
include(dbCon.php);
$id = $_GET['id'];
$action = $_GET['action'];
$tableName = 'prerequest';
if($action=='delete'){
//deleting row
$sql = "DELETE FROM $tableName WHERE id='$id'";
$r = mysqli_query($con,$sql);
if($r){
$status="success";
//assuming this file is in your root folder
header('Location: manage-quotes.php');
}else{
$status="error ".mysqli_error($con) . ": " . mysqli_error($con);
}
echo $status;
}mysqli_close($con);
then call it with: delete-quote.php?id=1&action=delete
I recommend you to use a dynamic usage like Ajax calls instead an static in your button, by creating your onClick events using jQuery and remove rows dynamically with ajax calls.
Hope it works. Cheers
从delete-quote.php替换为“ $ sql”,如下所示:
$sql = "DELETE FROM prerequest WHERE id = '".$id."'";
Just use this solution
<?php
$servername = "localhost";
$username = "siyakhat_root";
$password = "";
$dbname = "siyakhat_ibroker";
$id = isset($_GET['id']) ? $_GET['id'] : '';
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// sql to delete a record
$sql = "DELETE FROM prerequest WHERE id = $id";
if ($conn->query($sql)) {
mysqli_close($conn);
header('Location: manage-quotes.php');
exit;
} else {
echo "Error deleting record";
}
?>
