Answers

The captcha image does not appear in my website. What can be happening?

Note that the image is not displayed when editing in Dreamweaver. The image is displayed when the page is loaded with a browser.

If you are not seeing the image in a browser, then there are three possibilities:

  • The folder HDWFormCaptcha has not been uploaded. In this case you need to upload it. Please note that the HDWFormCaptcha folder is generated in your local web site when you insert the captcha in your page, then you need to upload that folder to your online web server.
  • The path to the image (a PHP file) is wrong. Be sure that the paths in your local Dreamweaver matches with relative paths in your online web site
  • The GD 2 Image Library for PHP is not available. Maybe you can contact your web hosting service and request it.


How can I know if the GD 2.0 Library is present in my web server?

Most PHP servers contains the GD Image Library installed, it's almost an standard in every PHP installation.

There is a simple test to know the libraries installed with PHP. Follow this steps:

  1. Create a page named "phpinfo.php" with this single line: <?php phpinfo(); ?>
  2. Load the page in your web browser, for example http://www.your-web-site.com/phpinfo.php

You will see a page with a detailed information about the PHP capabilities on your web server, including the GD Library version available.

If your web hosting support is fast or if it offer an online help you can just ask them about the support for GD Library.



Do I need to add some verification code in the page that process the form?

No, no hand coding is needed or additional steps are required. The captcha verification code is inserted automatically into the web page that protects the form.

Note that the page that process the form (save it , or send by email, etc...) must exist before you apply the captcha to protect it.



Can I put more than one captcha instance in the same page?

It's not a common practice, but if the captchas contains the same configuration parameters (same with, height,...) you can add more than one.

Of course, in the same website you can use any number of captchas in different pages.



Can I put some sort of reset button to generate a new captcha image (ex: in case the user doesn't see clearly) ?

Yes, put this button into your page:

<input type="button" name="hdwnc" value="new image" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').src+'&'+Date();" />

This link makes the same function:

<a href="#captchaimg" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').src+'&'+window.Date();">new image</a>


Can I use Form2Mail and FormCaptcha in the same form?

To put Form2Mail and FormCaptcha together, please follow these steps:

  1. Insert Form2Mail into your form as always.
  2. Once inserted Form2Mail, insert FormCaptcha.
  3. Select the file "HDWForm2Mail/Form2Mail.php" as the page to protect.
  4. Click the "Browse" button to select this file.
  5. Configure others parameters of FormCaptcha in the "Insert Captcha"
  6. window, as always.
  7. Update all the files in your web server.

These automatically will generate all the code needed to achieve the functionality.



Is it possible to change the return link so that when the page refreshes, it jumps back down to the captcha image instead of the top of the page?

Yes, follow these steps:

1 - Add an empty anchor at the bottom of your page like this one:

<a name="captcha"></a>

2- Add #captcha to the end of your "Redirect on failed" page, example:

mypage.php?hdwmsg=invalid#captcha


Some of my fields are not being re-filled when the captcha code entered is incorrect, any solution?

Please do not use spaces in the field names, use underscore _ instead spaces.

Adidtionally, if you are not using spaces, note that in Internet Explorer the "select" fields need the "value" specified in order to be able to refill those fields with javascript.

Example (incorrect):

<select name="my field">
<option>Blue</option>
<option>Red</option>
<option>Green</option>
</select>

Example (correct):

<select name="my_field">
<option value="Blue">Blue</option>
<option value="Red">Red</option>
<option value="Green">Green</option>
</select>

Please add the value attributes to the option tags.



The form is submitted even if I don't type the captcha code. How can I prevent this?

If the form is submitted even if you don't type the captcha code then the cause is one of the following:

  1. The page that processes the form wasn't selected as the "page to protect";

  2. .... or the page that processes the form wasn't uploaded to the online website after adding the captcha.

When you insert the captcha into your form, you must select processing page (where the form data is posted to) as the "page to protect". That way the captcha image will be inserted into your form and the captcha verification code will be inserted into the page that processes the form.

After this step, please remember to upload both the page that contains the form and the page that processes the form to your online webserver. Remember to upload also the "HDWFormCaptcha" folder that was generated into your website.


When I double click the MXP file I'm getting this error: "Extension requires more recent version of Macromedia Extension Manager". How can I solve this?

Download the most recent version of the Adobe/Macromedia Extension Manager or the version related to your Dreamweaver version:

After installed open the MXP file from the Extension Manager menu to be sure that you are installing the extension using the correct Extension Manager.

I'm getting this error message "Is not possible to create data structure.". What's happening?

Please, change the "Links relative to" setting in the site configuration options (Dreamweaver 8 or later).

If this setting does not solve the problem, then follow these steps:

  1. Restart Dreamweaver
  2. Be sure that you have a local web site defined in Dreamweaver
  3. Open the page where you want to insert the extension(this page must be saved previously into your web site)
  4. Try to insert the extension again


Can I pay using my credit card ?

Yes, Paypal allows you to pay directly using your credit card.

We also accept MoneyBookers (accepts credit cards when uploading funds).


Can I use these extensions with MACs ?

Yes, you can. These extensions are tested in all actual browsers and used from Dreamweaver on both platforms, PC and MAC.


I have downloaded the new program, but cannot seem to access it from the command panel.

Did you restart Dreamweaver after double clicking the MXP file? Please remember to restart Dreamweaver after double clicking the MXP file.


I'm getting this message "Please define your site first.". What I should do?

It's required to define a working site in Dreamweaver because Dreamweaver needs to know where to place the files.

Download here a PDF document with help about defining a site in Dreamweaver.



This extension works with Dreamweaver CS5?

Yes, all our extensions are compatible with the most recent Dreamweaver versions, including Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8, Dreamweaver CS3, Dreamweaver CS4 and Dreamweaver CS5.


When I preview my web page after I get this message in my Internet Explorer,"To help protect your security, Internet Explorer has restricted...". What is the problem?

If you are testing your page directly from your local hard disk in IE 7, this message appears:

"To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer. Click here for options."

In IE 7 this message appears when you test a web page that contains a script or Flash item directly form your local hard disk. When you upload your page to an online web server that message does not appear.

The address from a web server must start with http:// or https:// . On the other hand if the address starts with C:\ or file:// then you are testing it from your local hard disk.

Just upload your web page to your web site and you will see that the error disappears.

I'm getting this error: "TypeError: THE_DOM has no properties" . There is a workaround?

Please follow these steps:
  1. Check if  you have defined a local web site at dreamweaver.
  2. Check if you have saved the page into your local web site.
  3. If you are using Dreamweaver templates, check if your templates allow an "Editable Region" in the <HEAD> section of the HTML code.
  4. Mark the "Use case-sensitive link checking" option in the site settings and recreate your site cache.
  5. After these checks, please restart your Dreamweaver and try again.
If the above actions don’t solve the problem, then probably the reason is a wrong HTML structure in the page that you are trying to use the product, in this case, please check the page’s HTML structure and if you cannot find the problem then contact our support service.


I'm getting the error "Can't update menus. Extension will not be installed". What is the solution?

That's due to a bug in the Adobe Extension Manager that sometimes corrupts the "Menus.xml" file. That file can be found in the following location:

Windows users: C:\Documents and Settings\[UserName]\Application Data\Macromedia\Dreamweaver [version]\Configuration\Menus\menus.xml

Mac users: HD:Users:username:Library: Application Support:Macromedia:Dreamweaver [version]:Configuration:Menus:Menus.xml

To fix this problem close your Dreamweaver and try the following:

  1. Un-install all your extensions and then re-install them one at a time. This will work in most cases.
  2. If the above doesn't work then delete the "Menus.xml" file. After this you will need to disable and enable your extensions in order to get the menu entries again.
  3. If none of the above works then there is more than one file corrupted, the solution in this case will be to completely uninstall Dreamweaver and reinstall it again.
