Hi i am trying to insert data in database but $wpdb->insert insert two rows.

my code for insert data is

global $wpdb;
    $tablename = $wpdb->prefix . '<TABLE NAME>';
 for ($i = 0; $i < sizeof($emails); $i++) {

                $data = array("post_id" => $post_id,
                    "user_id" => $user_id,
                    "email" => $emails[$i], 
                    "status" => 1
                     $wpdb->insert($tablename, $data);


size of $emails is 1 (if i am inserting one email id).

Where am i making mistake please let me know.

  • As far I know, $wpdb->insert() is intended to insert columns (one or more) in one row, you can not use it to insert data in two rows. – cybmeta Oct 28 '15 at 12:46

    Please show more of your code, this one looks fine to me – M-R Oct 28 '15 at 12:48
  • i am trying to insert only one row but this function is inserting two rows into the database. – Bushra Shahid Oct 28 '15 at 12:49
  • @M-R Just Edited my code please review it. – Bushra Shahid Oct 28 '15 at 12:54
  • Have you tried pulling it out of the loop to make sure its not the loop? – M-R Oct 28 '15 at 12:57

Try something like this

function insert_data_into_table () {
        global $wpdb;
        $table_name = $wpdb->prefix . "your_table_name";

        //Check if table exists
        if($wpdb->get_var("show tables like '$table_name'") != $table_name) :

            //if not, create the table   
            $sql = "CREATE TABLE " . $table_name . " (
            ) ENGINE=InnoDB;";

            require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
          foreach($emails as $mail):
              $insert = "INSERT INTO  " . $table_name . "
                (post_id, post_id, email, post_id) 
                VALUES ($post_id, $user_id, email['content'], 1);"
              $results = $wpdb->query( $insert );

I'm assuming that $email is an array containing some data? If you want to save the entire array, then you should serialize() the array.
