How to insert a single row to WP database table?

Question

Intro:

I have a function that handles a contact form variables in my website.

• user enters name, email and text.
• function.php gets variables using javascript.
• I get more information on the user on the way - like IP, Country, UTM tags if any, ect.

Then I added a code part that saves the variables respectively on a SQL table.

I created the table 'wp_contact_form' using phpMyAdmin.

used this code part in a function:

global $wpdb; 

$wpdb->insert( 
    'wp_contact_form', 
    array( 
        'con_ip'          => $_COOKIE['ip'], 
        'con_name'        => $fullname, 
        'con_email'       => $email, 
        'con_text'        => $message, 
        'con_country'     => $_COOKIE['country'], 
        'con_reigon'      => $_COOKIE['region'], 
        'con_city'        => $_COOKIE['city'], 
        'con_utm_source'  => $_COOKIE['utm_source'], 
        'con_utm_medium'  => $_COOKIE['utm_medium'], 
        'con_utm_campain' => $_COOKIE['utm_campaign'], 
        'con_utm_term'    => $_COOKIE['utm_term'], 
        'con_utm_content' => $_COOKIE['utm_content']
    ), 
    array( 
        '%s', 
        '%s', 
        '%s', 
        '%s', 
        '%s', 
        '%s', 
        '%s', 
        '%s', 
        '%s'
    ) 
);

And I still get a blank table. I tried following this: https://codex.wordpress.org/Class_Reference/wpdb#INSERT_rows

without any success.

Full function code:

/**
    Contact form using Ajax 
**/ 

add_action('wp_ajax_nopriv_submit_contact_form', 'submit_contact_form'); 

// Send information from the contact form 
function submit_contact_form(){

    //$utm = get_the_utm_vars();

    // If there is a $_POST['email']...
    if( isset($_POST['email']) && ($_POST['validation'] == true ) ) {

        // Get parameters
        $email = $_POST['email']; // Gets the email of the user..
        $email_to = "arik@ example.pro";
        $utm_emails = array(
            'tova@ example.pro',
            'yonatan@ example.pro', 
            'arik@ example.pro',
            'gal@ example.pro',

            // Tells me that the mail has been sent

            //Add the UTM variables to the emails text

            // A mail for tova with the UTM paramseters
            wp_mail($utm_emails,$email_subject,$message,$utm_headers);


        } else {
            echo json_encode(array("result"=>"mail_error"));
            var_dump($GLOBALS['phpmailer']->ErrorInfo);
    }
        wp_die();
    }










    global $wpdb; 

    $wpdb->insert(

Answer 1

In your code, if an email is set and validated (which I suppose should be the normal case), your code will exit at wp_die(), and never reaches the $wpdb->insert.

Your $wpdb->insert statement will only ever be reached if an email is not set, or if "validation" is false.

You might want to get rid of the wp_die() call altogether, or place that call at the very end of your function, depending on your needs.

Other than that, try determining whether your function is called at all (might be something wrong with the AJAX call itself).
