UAE Arabic Localized CAPTCHA Images

Example Captcha images generated by BotDetect using the base Arabic character set for all Captcha ImageStyle values can be seen in the BotDetect Captcha image styles demo

To use BotDetect Captcha images localized for the UAE Arabic Captcha Locale in your application, you can specify the Locale value:

• In PHP applications, you can use either the application-global setting in the lib/botdetect/CaptchaConfig.php file:

  // Set the default Locale for all Captcha instances in the 
  // PHP application to UAE Arabic
  $LBD_CaptchaConfig->Locale = 'ar-AE';

  or the Captcha object instance-specific value:

  <?php 
    $SampleCaptcha = new Captcha("SampleCaptcha");
    $SampleCaptcha->UserInputID = "CaptchaCode";
    // Set the Captcha object instance Locale to UAE Arabic
    $SampleCaptcha->Locale = 'ar-AE';
    echo $SampleCaptcha->Html(); 
  ?>

  Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

  <input name="CaptchaCode" type="text" id="CaptchaCode" dir="rtl" />

• In ASP.NET applications, you can use either the .aspx page source:

  <!-- Captcha control localized to UAE Arabic -->
  <BotDetect:Captcha ID="SampleCaptcha" runat="server" Locale="ar-AE" />

  or the page code-behind:

  [C#]
      
  // Set the Captcha instance Locale to UAE Arabic    
  SampleCaptcha.Locale = "ar-AE";

  [VB.NET]
      
  ' Set the Captcha instance Locale to UAE Arabic    
  SampleCaptcha.Locale = "ar-AE"

  Locale-dependent Captcha strings can be configured in the <botDetect> Web.config configuration section.

  Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

  <asp:TextBox ID="CaptchaCodeTextBox" runat="server" dir="rtl"></asp:TextBox>

• In ASP Classic applications, you can use either the application-global setting in the BotDetect\CaptchaConfig.asp file:

  ' Set the default Locale for all Captcha instances in the 
  ' Classic ASP application to UAE Arabic
  LBD_Configuration_Locale = "ar-AE"

  or the Captcha object instance-specific value:

  <%
    Dim SampleCaptcha : Set SampleCaptcha = (New Captcha)("SampleCaptcha")
    SampleCaptcha.UserInputID = "CaptchaCode"
    ' Set the Captcha object instance Locale to UAE Arabic
    SampleCaptcha.Locale = "ar-AE"
    Response.Write SampleCaptcha.Html
  %>

  Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

  <input name="CaptchaCode" type="text" id="CaptchaCode" dir="rtl" />

UAE Arabic Localized audio CAPTCHA Sounds

Example audio Captcha sounds generated by BotDetect using the Arabic UAE Locale setting can be heard in the BotDetect Captcha features demo

To use BotDetect sounds localized for the UAE Arabic Captcha Locale, you should also download the UAE Arabic Pronunciation Sound Package and deploy the .bdsp file to the BotDetect sounds folder your application uses:

• PHP applications always use lib/botdetect/Resources/Sounds.
• ASP.NET applications use Bin\BotDetectSounds by default. A custom folder can be specified in the <botDetect> configuration section.
• ASP Classic applications use Redistribute\BotDetectSounds in the BotDetect installation folder by default. A custom folder can be specified in the BotDetect/CaptchaConfig.asp file.
