wpdb update query not working

0 Views

I’ve made an email script that should update as soon as wp_mail has result. For some reason my value won’t update. Have I missed something? I am receiving the mail so the wp_mail works.

Cheers!

$email_result = wp_mail( $to, $subject, $message, $headers );

if( $email_result ){//wp_mail() processed the request successfully
    global $wpdb;
    $table_name = $wpdb->prefix . "wpsc_coupon_codes";
    $coupon_id = $ereminder->ID;

$ereminders = $wpdb->query( $wpdb->prepare("
    UPDATE *
    FROM $table_name
    SET reminder = 1
    WHERE ID = $coupon_id
") );

}

  3. We could use $wpdb->update, like this:

     global $wpdb;
 $table_name = $wpdb->prefix.'your_table_name';
 $data_update = array('row_name_1' => $row_data_1 ,'row_name_2' => $row_data_2);
 $data_where = array('row_name' => $row_data);
 $wpdb->update($table_name , $data_update, $data_where);

  4. You may change instead of (UPDATE * FROM)

    $ereminders = $wpdb->query($wpdb->prepare("UPDATE $table_name SET reminer='1' WHERE ID=$coupon_id"));

    and use no break.

    Thank you.

  5. Example of mine that is working:

    $result = $wpdb->update(
    $wpdb->prefix .'sae_calendar', 
    array( 
        'year' => $year,
        'quarter' => $quarter,
        'start_date' => $start_date,
        'end_date' => $end_date,
        'reservation_start_date' => $reservation_start_date,
        'reservation_end_date' => $reservation_end_date 
    ), 
    array(
        "id" => $id
    ) 
);

  6. <?php 
  global $wpdb;
    if(isset($_POST['progress'])){
    $table=t_test;
    $data=array('client_development'=>$_POST['Progress']);
    $where=array('p_id'=>$_SESSION['id']);
    $format=("%d");
    $whereFormat=("%d");
    $result4=$wpdb->UPDATE($table,$data,$where,$format,$whereFormat);
  }
?>
<form method="post">
  <input type="text" name="Progress">
  <input type="submit" name="progress" value="Prog%">
</form>
<?php 
if(isset($_POST['progress'])){
$table=t_test;
    $data=array('client_development'=>$_POST['Progress']);
    $where=array('p_id'=>$_SESSION['id']);
    $format=("%d");
    $whereFormat=("%d");
    $result4=$wpdb->UPDATE($table,$data,$where,$format,$whereFormat);
}
?>
<form method="post">
  <input type="text" name="Progress">
  <input type="submit" name="progress" value="Prog%">
</form>
