Thanks Thomas! 2008-03-02 Added licensing terms under the MIT License Only remove unprocessable HTML tags if they exist in the array 2009-06-03 Normalize existing CSS (style) attributes in the HTML before we process the CSS. Made it so that the display:none stripper doesn't require a trailing semi-colon. 2009-08-13 Added support for subset class values (e.g. "p.class1.class2"). Added better protection for bad css attributes. Fixed support for HTML entities. 2009-08-17 Fixed CSS selector processing so that selectors are processed by precedence/specificity, and not just in order. 2009-10-29 Fixed so that selectors appearing later in the CSS will have precedence over identical selectors appearing earlier. 2009-11-04 Explicitly declared static functions static to get rid of E_STRICT notices. 2010-05-18 Fixed bug where full url filenames with protocols wouldn't get split improperly when we explode on ':'... Thanks Mark! Added two new attribute selectors 2010-06-16 Added static caching for less processing overhead in situations where multiple emogrification takes place 2010-07-26 Fixed bug where '0' values were getting discarded because of php's empty() function... Thanks Scott! 2010-09-03 Added checks to invisible node removal to ensure that we don't try to remove non-existent child nodes of parents that have already been deleted / class acymailingEmogrifier{ private $html = ''; private $css = ''; private $unprocessableHTMLTags = array('wbr'); public function __construct($html = '', $css = ''){ $this->html = $html; $this->css = $css; } public function setHTML($html = ''){ $this->html = $html; } public function setCSS($css = ''){ $this->css = $css; } // there are some HTML tags that DOMDocument cannot process, and will throw an error if it encounters them. // these functions allow you to add/remove them if necessary. // it only strips them from the code (does not remove actual nodes). public function addUnprocessableHTMLTag($tag){ $this->unprocessableHTMLTags[] = $tag; } public function removeUnprocessableHTMLTag($tag){ if(($key = array_search($tag, $this->unprocessableHTMLTags)) !== false) unset($this->unprocessableHTMLTags[$key]); } public static function strtolower($matches){ return strtolower($matches[0]); } // applies the CSS you submit to the html you submit. places the css inline public function emogrify(){ $body = $this->html; // process the CSS here, turning the CSS style blocks into inline css if(count($this->unprocessableHTMLTags)){ $unprocessableHTMLTags = implode('\|', $this->unprocessableHTMLTags); $body = preg_replace("/<($unprocessableHTMLTags)[^>]>/i", '', $body); } //$encoding = mb_detect_encoding($body); $encoding = 'UTF-8'; $body = mb_convert_encoding($body, 'HTML-ENTITIES', $encoding); $xmldoc = @ new DOMDocument; if(!is_object($xmldoc) \|\| !method_exists($xmldoc, 'loadHTML')) return $this->html; $xmldoc->encoding = $encoding; $xmldoc->strictErrorChecking = false; $xmldoc->formatOutput = true; //ACYBA MODIFICATION : let's avoid some warnings //Disable the loadHTML function errors which may crash some servers. if(function_exists('libxml_use_internal_errors')) libxml_use_internal_errors(true); @$xmldoc->loadHTML($body); $xmldoc->normalizeDocument(); $xpath = new DOMXPath($xmldoc); // before be begin processing the CSS file, parse the document and normalize all existing CSS attributes (changes 'DISPLAY: none' to 'display: none'); // we wouldn't have to do this if DOMXPath supported XPath 2.0. $nodes = @$xpath->query('//'.'[@style]'); if($nodes->length > 0) foreach($nodes as $node){ $node->setAttribute('style', preg_replace_callback('/[A-z\-]+(?=\:)/S', array($this, 'strtolower'), $node->getAttribute('style'))); } // get rid of css comment code $re_commentCSS = '/\/\.\\//sU'; $css = preg_replace($re_commentCSS, '', $this->css); static $csscache = array(); $csskey = md5($css); if(!isset($csscache[$csskey])){ // process the CSS file for selectors and definitions $re_CSS = '/^\s([^{]+){([^}]+)}/mis'; preg_match_all($re_CSS, $css, $matches); $all_selectors = array(); foreach($matches[1] as $key => $selectorString){ // if there is a blank definition, skip if(!strlen(trim($matches[2][$key]))) continue; // else split by commas and duplicate attributes so we can sort by selector precedence $selectors = explode(',', $selectorString); foreach($selectors as $selector){ // don't process pseudo-classes if(strpos($selector, ':') !== false) continue; $all_selectors[] = array( 'selector' => $selector, 'attributes' => $matches[2][$key], 'index' => $key, // keep track of where it appears in the file, since order is important ); } } // now sort the selectors by precedence usort($all_selectors, array('self', 'sortBySelectorPrecedence')); $csscache[$csskey] = $all_selectors; } for($a = count($csscache[$csskey]) - 1; $a >= 0; $a--){ // query the body for the xpath selector $nodes = @$xpath->query($this->translateCSStoXpath(trim($csscache[$csskey][$a]['selector']))); if(empty($nodes)) continue; foreach($nodes as $node){ // if it has a style attribute, get it, process it, and append (overwrite) new stuff if($node->hasAttribute('style')){ // break it up into an associative array $oldStyleArr = $this->cssStyleDefinitionToArray($node->getAttribute('style')); $newStyleArr = $this->cssStyleDefinitionToArray($csscache[$csskey][$a]['attributes']); // new styles overwrite the old styles (not technically accurate, but close enough) //Changed by Acyba, we don't overwrite the old styles, we keep them and add only the new ones //$combinedArr = array_merge($oldStyleArr,$newStyleArr); $combinedArr = array_merge($newStyleArr, $oldStyleArr); $style = ''; foreach($combinedArr as $k => $v) $style .= (strtolower($k).':'.$v.';'); } else{ // otherwise create a new style $style = trim($csscache[$csskey][$a]['attributes']); } $node->setAttribute('style', $style); } } //Adrien : we don't need that... it removed display:none elements from the Newsletter, we may need them with media query // This removes styles from your email that contain display:none.
