Frequently Asked Questions
Common questions about Simple Ajax Chat – Add a Fast, Secure Chat Box
Open the directory /resources/audio/ and replace the files msg.mp3 and msg.ogg with your desired audio files. You will notice lots of alternate sound files included in that same directory. Simply rename any pair of files to replace the defaults.
Check out sac.css located in the resources directory.
Yes, please see this post at WP-Mix.com: Auto-Clear Chats.
Yep, the chat plugin works great on iPhones, Android devices, and just about anything that supports JavaScript.. the functionality is achieved using Ajax.
Yes, check out Simple Ajax Chat .htaccess whitelist and/or Whitelist POST access with .htaccess
Add this CSS: #sac-latest-message { display: none; } You can add that to the plugin setting, "Custom CSS styles" or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, "Enable custom styles" also is enabled.
Add this CSS: #sac-form label { display: none; } You can add that to the plugin setting, "Custom CSS styles" or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, "Enable custom styles" also is enabled.
You can hide the "say it" submit button, so the user must press enter to submit chats. Add this CSS: #sac-user-submit { display: none; } You can add that to the plugin setting, "Custom CSS styles" or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, "Enable custom styles" also is enabled.
Simple Ajax Chat is designed to look great on any of the default WP themes and most other themes as well. Even so, every theme is different, and it's impossible to test on the hundreds of thousands of themes that are available. So if the chat form is not looking awesome on your theme, it's because your theme for whatever reason is applying its own particular styles. If this is the case, you can try disabling the plugin setting to "Enable custom styles". If that doesn't help, you can include your own custom CSS, or customize the plugin's default styles. Alternately, you may include custom CSS via your theme's stylesheet, and/or modify your theme's CSS as needed to make things display as desired. Tip: to see how the chat form should look, check it out using any of the default WP themes.
If this is happening, and/or if you are receiving a "Failed opening required" error message, most likely your site's wp-load.php file is not located in the usual default location (i.e., it has been moved to a custom location). If this is the case, you will need to edit the paths in /simple-ajax-chat-core.php (line 4) and /resources/sac.php (line 10). At some point I will be revamping the plugin so that this modification won't be necessary.
