=== Infinite-Scroll === Contributors: beaver6813, dirkhaim, paul.irish, benbalter Donate link: http://www.infinite-scroll.com Tags: ajax, pagination, scrolling, scroll, endless, reading Requires at least: 3.2 Tested up to: 3.5 Stable tag: 2.6.2 Automatically append the next page of posts (via AJAX) to your page when a user scrolls to the bottom. == Description == Infinite scroll has been called autopagerize, unpaginate, endless pages. But essentially it is pre-fetching content from a subsequent page and adding it directly to the user’s current page. When a user scrolls towards the bottom of the page, the next page of posts is automatically retrieved and appended. This means they never need to click "Next Page", which *dramatically increases stickiness*. Features: * Works out-of-the-box for many popular WordPress themes -- just activate the plugin and scroll * Fully customizable to adapt to your site and theme * Requires no (hopefully) template hacking, only a knowledge of CSS selectors. * Relies on shared database of common themes to simplify installation process * Maintain local database of theme presets for all installed themes (shared across network on multisite installs) * Countless API endpoints to modify the behavior. * Backwards compatible: Will not break RSS readers, mobile devices, or browsers with javascript Full information on [infinite-scroll.com](http://www.infinite-scroll.com) == Changelog == = 2.5 = * Plugin completely rewritten from the bottom up * **Note: you will need to manually reactivate this plugin after upgrading** * Minimum WordPress version required now to **3.2** * Added support for internationalization (see FAQ for information on translating) * Added support for custom post types (now works on all pages but `is_singular()`) * Options screens significantly simplified with additional help text * Presets screen now uses standard WordPress administrative interface * Ability to submit your theme's CSS Selectors to the community CSS selector database to aid others with installation * Changes to presets are now made inline; saved via AJAX without page reload * Added additional API endpoints for developers to modify and customize plugin behavior * Loading image now uses native WordPress uploader and can accept arbitrary URL or image from media gallery * Loading and finished text now uses native WordPress TinyMCE editor * If site administrator has not entered CSS selectors and preset is known, plugin will default to preset * Any preset entered by site (or network) administrator will now override community contributed presets by default * Community contributed CSS selector presets are now stored in the database allowing for plugin directory to be unwritable (security enhancement) * Prompts users to default to CSS selector preset when available * Presets now support child themes * Community contributed CSS selectors now stored as standard CSV and asynchronously update daily (performance and compatibility enhancement) * Site (or network) specific CSS selector presets are now stored in the database (security enhancement) * CSS Preset updater now uses WP_HTTP class (compatibility enhancement) * Javascript file now served directly to user (rather than proxied via PHP) to allow for browser caching, minification, serving via CDN, and better integration with caching plugins (performance enhancement) * Javascript options stored natively in database and passed directly to script via WordPress's `wp_localize_script` function (performance and customizability enhancement) * No longer relies on deprecated user levels to determine permissions * Default loading and fished messages changed * Fixes for error and warnings when run with `WP_DEBUG` enabled * Removed prompt for option to activate infinite scrolling for only certain users (defaults to all) * Removed prompt for option to toggle debug mode (defaults to `WP_DEBUG` or `SCRIPT_DEBUG`) * Removed prompt for option to toggle scrolling behavior (defaults to automatic) * Removed prompt for additional callbacks * Removed prompt to select image alignment (defaults to left, can override via CSS) * Significant code clean up, file reorganization, and in-line documentation to conform to WordPress coding and style standards (whitespace, double v. single quotes, tab drift, trailing commas, closing PHP tags, etc.) * Classes loaded as sub-classes (rather than extending parent class) to prevent classes from becoming out of sync * Added phpdoc style documentation * Plugin file name changed to conform to standard WordPress naming conventions * License (GPL) included with distribution * Version numbering simplified = 2.0b2.120111 = * Added infinite_scroll_load_override filter to

Edit theme presets screen == Frequently Asked Questions == = What exactly is infinite scrolling? = Essentially it is pre-fetching content from a subsequent page and adding it directly to the user’s current page. [More Information](http://www.infinite-scroll.com/the-interaction-design-pattern/) = Can I change the number of posts loaded? = Yes. Go to Settings -> Reading in your WordPress administrative dashboard. = How do I change the alignment of the loading image? = Add the following to your theme's css: `#infscr-loading img { text-align: ALIGNMENT; }` where "ALIGNMENT" is either `left`, `right`, or `center`. = How can I pass additional arguments such as behavior or callbacks to the script? = Add a filter to `infinite_scroll_options` and adds additional options to the options array. = Is the plugin available in my language? = If you enjoy the plugin and are interested in contributing a translation (it's super easy), please take a look at the [Translating WordPress](http://codex.wordpress.org/Translating_WordPress) page. = Is it SEO-Friendly? = Yes all enhancements are made via javascript only, so search spiders see no difference. = Is it accessible? = Things won’t change for screen-readers. This technique degrades gracefully. = Does it still keep going, even at the end of the blog? = Infinite scroll is configured to die when it hits a 404 Not Found status code, so when it goes through all your archives it should hit a /page/43/ (or something) that doesn’t exist, then show a message "Congrats, you’ve reached the end of the internet." Some WordPress themes don’t report not found pages with a 404. Try a different theme or contacting the theme author. = Do I need to edit my theme to make this work? = Probably not, nope. = How do I pass additional arguments such as callbacks to the Infinite Scroll script? = To pass additional arguments to the Infinite Scroll script, add the following code to either your theme's `functions.php` or to a stand-alone plugin file. ``` function my_infinite_scroll_options_filter( $options ) { $options['callback'] = 'my_callback'; $options['another_parameter'] = 'another_value'; return $options; } add_filter( 'infinite_scroll_js_options', 'my_infinite_scroll_options_filter' ); ``` == Installation == = Automatic Install = 1.
