How do I do that? As this stands right now, every time there are errors, it generates a blank page with all the errors listed. I don't want that. http://stackoverflow.com/questions/36878170/how-to-display-errors-on-the-same-page-php-form Here's a basic form that I ripped off from a tutorial somewhere test.php:
'; } } else { $errors .= 'Please enter your name.
'; } if ($_POST['email'] != "") { $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL); if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { $errors .= "$email is NOT a valid email address.
"; } } else { $errors .= 'Please enter your email address.

or password it does not show error it simply shows blank page Please help me to show error meassge for wrong password or username. loginform.php(html error messages code)
By default, the script will issue any error messages on the screen after the form is submitted. The form is not shown, and the user has to hit "back" to get back to the form (the standard error message page can be customized, have a look at the "Customizing error messages" page on the support section for more information). If you would like the user to be returned to your form page when errors occur and have the error messages shown along with the form, you will need to add some code to your form page to display the errors (the script can't do that for you). You will also need to enable the $show_errors_on_form_page option, and enter a value for the $form_page_url variable (instructions in the script). Your form page needs to be a PHP page, with a .php extension, like contact.php for example. If it's an HTML page, just save it with a .php extension. By displaying the errors on the form page, it will appear to the visitor that they have not left the page. (If you are new to editing PHP code, have a look at the "Editing PHP code" page in the support section.) Add this code to your form page: Put this at the top (if "session_start();" is not already there): Then put this code on your page where you would like the errors to appear: "; foreach($_SESSION['formtoemail_form_errors'] as $form_error_value){print "" . stripslashes($form_error_value) . "
";} print ""; unset($_SESSION['formtoemail_form_errors']); } ?> It is recommended that you enable the $pre_populate_form option in the script and add the appropriate code for it in your form page (see the "Pre-populate the form" page in the support section). This means the form values will be retained in the form in the event of
