Help, Troubleshooting & Common issues

Registration error

If you see the message "An error occurred during the registration process.", or any PHP error, or white page:

You have to enable the PHP CURL extension.

Restart your PHP server. Then the installer will work.

Can't connect to licensing server

You entered your purchase code with a trailing space.

Your copy of PHP Form Builder is NOT authorized

This error occurs if you registered your license with a different URL (HTTP/HTTPS; www or without www) than the one you use to access your page.

The solution is to always use the same URL, for instance, https://www.your-domain.com. Regardless of PHP Form Builder, it is a good practice to adopt. It will also improve your SEO.

Reinstall PHP Form Builder

A Regular license allows two installations - one for your localhost & the other for your production server.

If you want to change the installation URL (domain, folder, ...), you have first to uninstall PHP Form Builder from your initial URL. Then reinstall it on the new one.

To uninstall PHP Form Builder:

1. Open your registration URL - phpformbuilder/register.php
   You should see a message saying that Your PHP Form Builder copy is already registered on this domain.
2. Enter your purchase code & click the Unregister button
3. You can register again on a different domain/URL.

If for any reason you can't unregister your copy & want to reinstall it, please get in touch with me,
send me your purchase code & delete phpformbuilder/[your-domain]/license.php from your server.
I'll remove your installation license from the server then you'll be able to reinstall it elsewhere.

White page / Error 500

If your page is white or returns "HTTP ERROR 500", you have a PHP error.

To display the error message, you have to enable PHP display errors.

1. Add the following code just after use statements :
   

   <?php
   use phpformbuilder\Form;
   use phpformbuilder\Validator\Validator;
   
   // add the line below to your code :
   ini_set('display_errors', 1);

2. Refresh your page. Then you'll see what error is thrown and probably find solutions in other parts of this document.
   Once you have solved your problem, remove the ini_set() line if you don't want errors to be displayed anymore.

If the ini_set() function does not work on your server, you have to turn display_errors On in your php.ini

If you installed PHP Form Builder in a subfolder make a global search / replace from your IDE to change all the includes at once:

<?php
// Search this:
include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/phpformbuilder/autoload.php';

// Replace with this:
include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/your-dir/phpformbuilder/autoload.php';

Explanation

PHP Form Builder requires a single file, which is always called using PHP include_once() function :

<?php
include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/phpformbuilder/autoload.php';

If the path to file inside parenthesis is wrong Form.php is not found.

You've got to set the right path leading to your phpformbuilder directory.

To solve the problem:

• Change the path of the include to point to the correct folder:
  

  <?php
  // replace "your-dir" with yours in the following line
  include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/your-dir/phpformbuilder/autoload.php';

OR

• Open ../phpformbuilder/server.php in your browser and follow the instructions.

Fatal error: Class 'phpformbuilder\Form' not found

See Warning: include_once([...]) (same error, same solution)

Fatal error: Call to undefined function phpformbuilder\mb_strtolower()

PHP Form Builder uses the PHP mb_string extension to send emails with the correct encoding.

PHP mb_string extension allows working with a multi-byte encoding (UTF-8, ...).

PHP mb_string extension is not a default PHP extension but is enabled on most servers.

If it's not enabled on yours, you've got two solutions:

1. (Best solution) Install/Enable PHP mb_string.
   Depending on your server and system, many explanations are available on the web to know how to proceed.
2. 1. Open phpformbuilder/Form.php and replace all occurrences of mb_strtolower with strtolower.
   2. If your PHP Form Builder version is <= 3.5.2, replace

      $charset = mb_detect_encoding($mergedHtml);

      with:

      charset = 'iso-8859-1';
      if (function_exists('mb_detect_encoding')) {
          $charset = mb_detect_encoding($mergedHtml);
      }

      You'll find your version number in the comments at the beginning of phpformbuilder/Form.php
   3. Warning: You may experiment with encoding issues with multi-byte encoded characters (accents, special characters) when sending emails.

Plugins don't work

1. Open your browser's console (instructions here)

   You have to solve all errors you see in the console. Errors probably come from your page content, not from phpformbuilder itself.

   Be sure you include at first jQuery, THEN Bootstrap js, THEN phpformbuilder plugins code :

   <!-- jQuery -->
   <script src="//code.jquery.com/jquery.js"></script>
   <!-- Bootstrap JavaScript -->
   <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
   <?php
       $form->printIncludes('js');
       $form->printJsCode();
   ?>

    

2. PHP Form Builder is optimized for fast loading.

   It means that all the required plugins files (CSS & JavaScript) are automatically minified & concacenated.

   When you make changes to the form these files are automatically regenerated.

   The minified/concatendated files are located in phpformbuilder/plugins/min/[css|js]

   You can always safely remove the css & js files located in these 2 folders.
   They'll be regenerated and refreshed. This can in some cases solve cache issues.

   When you're in development, you can call the unminified unconcatenated files this way:

   // This will load the unminified unconcatenated files
   $form->setMode('development');

3. In a few cases, your server may not be correctly configured. The consequence is that the plugins URLs are wrong.

   Solution is to set the URL to plugins directory manually:

   // Set URL to match your plugins directory
   $form->setPluginsUrl('http://phpformbuilder/plugins/');

I do not receive the emails sent

1. Check that the sender_email address is from your domain (anything@your-domain.com).
   You must always use an email address from your domain as the sender when you send emails.
   Otherwise, you will not pass the spam filters, which will assume that you have usurped an identity.
   
   You can add a reply_to_email option to set to whom the reply will be sent.
2. Edit phpformbuilder/mailer/email-sending-test.php:
   Replace the sender email address L.16 with an email address from your domain.
   Open the file in your browser and fill in the form to send an email.
   If you still don't receive the message, contact your hosting provider and ask him to enable the PHP mail() function.

CSS issues

Included templates use a custom version of Bootstrap's css. You'll find it in phpformbuilder/templates/assets/stylesheets/bootstrap.min.css.

Set the correct path from your form to this css :

<!-- Bootstrap CSS - Change path with your own -->
<link href="assets/assets/css/bootstrap.min.css" rel="stylesheet">

... Or replace with Bootstrap CDN :

<!-- Bootstrap CSS CDN -->
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

Can't Submit form (using jQuery validation plugin)

jQuery validation plugin is complex and can have unexpected behaviors if it encounters configuration issues or malformed HTML.

To solve this :

1. Don't use any input, button, or other form element named "submit". It's not compatible with jQuery validation (reserved name).
2. Validate your code W3C validator
3. Open your browser's console (F12) and look for errors.
4. Open phpformbuilder/plugins-config/formvalidation.xml and use console.log (un-comment) to find out what's going on.

PHP SESSION settings error

You have an error in your PHP SESSION settings.

If you see this message when you post a form, the PHP SESSION variables could not be registered due to some wrong settings on your server.

• If session.cookie_secure is enabled in your php.ini and your URL is HTTP instead of HTTPS, the session cookies can't be sent. You must turn off session.cookie_secure in your php.ini or enable HTTPS.
• If you have a Set-Cookie directive in a .htaccess with the Secure value and your URL is HTTP instead of HTTPS, the session cookies can't be sent. You must disable this directive or enable HTTPS.
• Some other session settings may have to be reviewed in your php.ini or .htaccess, for instance, session.cookie_domain, session.cookie_httponly.

Migration

Migration from version 5.x to v6

PHP Form Builder 6 is a major update. Here's how to update your code to upgrade to the version 6:

1. The PHP Form Builder now uses an autoloader. Include the autoloader instead of including individual files:

   // old code:
   include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/phpformbuilder/Form.php';
   
   // replace with:
   include_once rtrim($_SERVER['DOCUMENT_ROOT'], DIRECTORY_SEPARATOR) . '/phpformbuilder/autoload.php';

2. Remove all the references to the fileuploader includes in your code. The fileuploader is now included in the autoload:

   // remove all the references to the fileuploader includes in your code:
   include_once $root . '/phpformbuilder/plugins/fileuploader/server/class.fileuploader.php';

3. The DB class has been replaced by PowerLite PDO. Please refer to the Database documentation for more information.
4. The Form::render() method now always echoes its output and has only one argument instead of two.
   A new Form::getCode() method is available to return the form code with or without debugging enabled.

   // old code:
   $form->render(bool $debug = false, bool $display = true);
   
   // replaced by:
   $form->render(bool $debug = false);
   $form->getCode(bool $debug = false);
   
   /* Examples of use */
   
   // render the form on the page without debugging
   $form->render();
   
   // render the form on the page with debugging (render the code inside a <pre></pre> tag)
   $form->render(true);
   
   // return the code without rendering it on the page
   $form->getCode();
   
   // return the code with debugging (return the code inside a <pre></pre> tag)
   $form->getCode(true);
