It also gives the administrator the option to collect or not collect user IP information. Aside from those two things, this plugin does not collect or store any user data. This plugin uses a few cookies for the chat functionality. It does not connect to any third-party locations. Minimal impact on privacy. **Translations** Simple Ajax Chat supports [translation into any language »](https://translate.wordpress.org/projects/wp-plugins/simple-ajax-chat) == Installation == **Installation** 1. Upload the plugin to your blog and activate 2. Visit the settings to configure your options [More info on installing WP plugins](https://wordpress.org/support/article/managing-plugins/#installing-plugins) **Usage** Once the settings are configured, you can display the form anywhere using the shortcode or template tag. __Shortcode__ Use this shortcode to display the chat box on a post or page: `[sac_happens]` __Template Tag__ Use this template tag to display the chat box anywhere in your theme template: `<?php if (function_exists('simple_ajax_chat')) simple_ajax_chat(); ?>` **Upgrades** To upgrade Simple Ajax Chat, remove the old version and replace with the new version. Or just click "Update" from the Plugins screen and let WordPress do it for you automatically. __Note:__ uninstalling the plugin from the WP Plugins screen results in the _removal of all settings and chat messages_ from the WP database. **Restore Default Options** To restore default plugin options, either uninstall/reinstall the plugin, or visit the plugin settings > Restore Default Options. **Uninstalling** Simple Ajax Chat cleans up after itself. All plugin settings and chat messages will be removed from your database when the plugin is uninstalled via the Plugins screen. **Stopping spam** This plugin works in two modes: * "Open Air" mode - anyone can chat * "Private" mode - only logged-in users can chat "Private" mode stops all automated spam, but registered users may still send "spammy" chat messages. Likewise, the "Open Air" mode is super effective at blocking automated spam, but some manual spam may get through. As a general rule, the longer your chat forum is online, the more of a target it will be for spam. Alternately/additionally you can [use .htaccess to block spammers](https://wp-mix.com/htaccess-block-spammer/). It's an easy, super-effective method for controlling access to your site. **Browser Notifications** SAC provides optional browser notifications. When enabled in the plugin settings, all of the notification stuff happens automatically, depending on your browser settings. For example, if your browser is set to deny all site notifications, then you won't see any SAC notifications. Likewise, if your browser is configured to allow notifications (and they are enabled in the settings), then you will see the notifications display whenever you are visiting the chat box and someone leaves a message. For more infos, check out the documentation for your specific browser. **Like the plugin?** If you like Simple Ajax Chat, please take a moment to [give a 5-star rating](https://wordpress.org/support/plugin/simple-ajax-chat/reviews/?rate=5#new-post).

Simple Ajax Chat: Chat Box 2. Simple Ajax Chat: Plugin Settings (panels toggle open/closed) More screenshots available at the [SAC Homepage](https://perishablepress.com/simple-ajax-chat/#screenshots). == Frequently Asked Questions == **How do I change the alert sound?** 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. **Where can I find a complete list of CSS selectors?** Check out `sac.css` located in the `resources` directory. **Can we auto-delete chat messages on a set time interval?** Yes, please see this post at WP-Mix.com: [Auto-Clear Chats](https://wp-mix.com/simple-ajax-chat-auto-clear-chats/). **Does it work with mobile devices?** Yep, the chat plugin works great on iPhones, Android devices, and just about anything that supports JavaScript.. the functionality is achieved using Ajax. **Is it possible to whitelist SAC plugin files?** Yes, check out [Simple Ajax Chat .htaccess whitelist](https://wp-mix.com/simple-ajax-chat-htaccess-whitelist/) and/or [Whitelist POST access with .htaccess](https://wp-mix.com/whitelist-post-access-htaccess/) **How do I hide "Latest Message: X minutes ago"?** 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. **How do I hide the Name, URL, etc. labels on the form?** 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. **How to remove the "say it" button?** 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. **The form is not displaying correctly, it looks all messed up?** 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. **The chat form is visible but new chats are not displayed.** 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. **How do I fix weird characters displayed in the chat box?** If you are seeing question marks or other weird characters or symbols in chat messages, you can try one of the following solutions: * Uninstall (delete) the plugin, and then re-install. Note that this technique resets all settings and deletes all chat messages. * Or, if you don't want to lose any settings or chat messages, you can run the following SQL command: `ALTER TABLE wp_ajax_chat CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;` Either of these techniques should resolve any weird character issues. Note that the SQL command assumes you are using the default database prefix, `wp_`. So make sure to edit that part of the command if you are using a custom database prefix. **How do I customize the login-required message?** By default, the login-required message is "You must be a registered user to participate in this chat." To customize this message, check out [this forum post](https://wordpress.org/support/topic/better-integration-with-buddypress/#post-9368504). **Chat Box not working in certain browsers (e.g., Chrome)?** Certain plugins (e.g., Shield Security) may implement security headers that prevent SAC from working properly. To resolve this issue, visit the "HTTP Headers" tab and go to "Security Headers tab" (or similar depending on which plugin you are using). There you can set the "Referrer Policy" to "Same Origin" and then save changes. SAC immediately should start working properly, but you also may need to clear the browser cache and hard reload the page. **How to translate form inputs?** If the form inputs like "Submit" button are not showing translation. You can work around by adding the following jQuery snippet: `<script>jQuery(function() { jQuery('#submitchat').val('Whatever'); });</script>` That needs to be included in your theme **after** jQuery is loaded. Then change `#submitchat` to the ID of the form input. Change `Whatever` to whatever you want to display for the text. **How to show the date/time of each chat?** Add the following CSS to the plugin setting, "Custom CSS styles": `ul#sac-messages li.sac-chat-message:before { content: "[ 'attr(data-time)' ]"; color: #777; }` After saving changes, that CSS will display the chat date/time next to each message, for example: [ 2021-08-30,08:35:57 ] Chat User: Hello this is a chat message left in August of 2021. **How to display chat box and form in vertical fashion?** By default, the chat box and form are displayed side by side. Here is a quick [tutorial](https://wp-mix.com/responsive-css-for-simple-ajax-chat/) to display them vertically, so the chat form is below the chat box. This is useful for optimizing SAC for limited space on the page. **Got a question?** Send any questions or feedback via my [contact form](https://plugin-planet.com/support/#contact) == Support development of this plugin == I develop and maintain this free plugin with love for the WordPress community.
