Inserting data in table database Wordpress

Johan Delft :

I am currently working on a piece of code that inserts data from a recent upload in the database. I tried different ways to make it work, however it does not work.

I tried the following at first:

$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);
// check upload status 
if (!$upload) { 
echo "Er is iets fout gegaan, excuses voor het ongemak";
} else {
  $sql = "INSERT INTO table (id, name) VALUES (1, 'Cake')";
  var_dump(error_get_last($sql));

The var_dump(error_get_last($sql)); returns NULL. I do not know why, a connection is not needed since Wordpress automatically makes a connection with the database.

I also tried the following:

$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);
// check upload status 
if (!$upload) { 
echo "Er is iets fout gegaan, excuses voor het ongemak";
} else {
// insert data in de database
$sql = "INSERT INTO $wpdb->wpex_programma (id, naam) VALUES (2, 'Country Kickin 2')";
$prepare_query = $wpdb->prepare($sql);
$result = $wpdb->sql($prepare_query);
echo '<pre>';
print_r($result);

Normally, when a user uploads a file, the user can view his file on the page. Because of this code, that was not possible anymore. I do not know how to solve it.

This is the whole if and else statement:

if ((!$conn_id) || (!$login_result)) { 
    echo "Het spijt ons, er is momenteel geen connectie met de server.";
    // echo "Attempted to connect to $ftp_server for user $ftp_user_name"; 
    exit; 
} else {
     // echo "upload is gelukt";
}

// upload het bestand
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);
// check upload status 
if (!$upload) { 
echo "Er is iets fout gegaan, excuses voor het ongemak";
} else {
// insert data in de database
$sql = "INSERT INTO $wpdb->wpex_programma (id, naam) VALUES (2, 'Country Kickin 2')";
$prepare_query = $wpdb->prepare($sql);
$result = $wpdb->sql($prepare_query);
echo '<pre>';
print_r($result);

// weergeef het bestand & download
    $contents = ftp_nlist($conn_id, $destination_folder);
    // doe dit aan als er ergens een error is: var_dump(error_get_last($contents));

   foreach ($contents as $mp3_url) { 
    $filename = basename($mp3_url, ".mp3");
// dit zorgt ervoor dat de punten niet te zien zijn.
if($filename == "..") {
  continue;
  print_r($filename);
}

if($filename == ".") {
  continue;
  print_r($filename);
}
?>

Also, the $result variable returns NULL when var_dump(error_get_last($result));

EDIT:

I changed:

else {
// insert data in de database
$sql = "INSERT INTO $wpdb->wpex_programma (id, naam) VALUES (2, 'Country Kickin 2')";
$prepare_query = $wpdb->prepare($sql);
$result = $wpdb->sql($prepare_query);
echo '<pre>';
print_r($result);

to:

else {

    // insert data in de database
global $wpdb

$number_of_rows_inserted = $wpdb->insert('wpex_programma', [
  'naam' => 'Country kickin 2'
]);
var_dump($number_of_rows_inserted);
print_r($result);

Alexis Vandepitte :

replace

$sql = "INSERT INTO $wpdb->wpex_programma (id, naam) VALUES (2, 'Country Kickin 2')";
$prepare_query = $wpdb->prepare($sql);
$result = $wpdb->sql($prepare_query);

with

$number_of_rows_inserted = $wpdb->insert('wpex_programma', [
   'id' => 2,
   'naam' => 'Country kickin 2'
]);

var_dump($number_of_rows_inserted);

The insert method is doing the prepare so y ou don't need it.

Add global $wpdb; at the start of your function or file if it's not done. Also, try to remove the line 'id' => 2 as the id should be set to auto increment.
