nekrozonMy ultimate goal is to make a unique widget that differs from the norm of my theme. However, my theme does not produce ids for the widget divs.
I was delighted to come across the following thread that shows how to edit functions.php so that widgets' divs get a unique ID:
http://wordpress.org/support/topic/153242
However, the conditional if (function_exists('register_sidebars')) in my functions.php uses a string that is replaced with the html in a later function:
if (function_exists('register_sidebars')) {
register_sidebars(3, array(
'before_widget' => '<!--- BEGIN Widget --->',
'before_title' => '<!--- BEGIN WidgetTitle --->',
'after_title' => '<!--- END WidgetTitle --->',
'after_widget' => '<!--- END Widget --->'
));
}There are two functions that setup the manipulation of the strings in the condition above. The second function art_sidebar sets up the array with the string and its corresponding html code for the replace. Anyways, here are the two functions:
function art_normalize_widget_style_tokens($content) {
$bw = '<!--- BEGIN Widget --->';
$bwt = '<!--- BEGIN WidgetTitle --->';
$ewt = '<!--- END WidgetTitle --->';
$bwc = '<!--- BEGIN WidgetContent --->';
$ewc = '<!--- END WidgetContent --->';
$ew = '<!--- END Widget --->';
$result = '';
$startBlock = 0;
$endBlock = 0;
while (true) {
$startBlock = strpos($content, $bw, $endBlock);
if (false === $startBlock) {
$result .= substr($content, $endBlock);
break;
}
$result .= substr($content, $endBlock, $startBlock - $endBlock);
$endBlock = strpos($content, $ew, $startBlock);
if (false === $endBlock) {
$result .= substr($content, $endBlock);
break;
}
$endBlock += strlen($ew);
$widgetContent = substr($content, $startBlock, $endBlock - $startBlock);
$beginTitlePos = strpos($widgetContent, $bwt);
$endTitlePos = strpos($widgetContent, $ewt);
if ((false == $beginTitlePos) xor (false == $endTitlePos)) {
$widgetContent = str_replace($bwt, '', $widgetContent);
$widgetContent = str_replace($ewt, '', $widgetContent);
} else {
$beginTitleText = $beginTitlePos + strlen($bwt);
$titleContent = substr($widgetContent, $beginTitleText, $endTitlePos - $beginTitleText);
if (' ' == $titleContent) {
$widgetContent = substr($widgetContent, 0, $beginTitlePos)
. substr($widgetContent, $endTitlePos + strlen($ewt));
}
}
if (false === strpos($widgetContent, $bwt)) {
$widgetContent = str_replace($bw, $bw . $bwc, $widgetContent);
} else {
$widgetContent = str_replace($ewt, $ewt . $bwc, $widgetContent);
}
$result .= str_replace($ew, $ewc . $ew, $widgetContent);
}
return $result;
}
function art_sidebar($index = 1)
{
if (!function_exists('dynamic_sidebar')) return false;
ob_start();
$success = dynamic_sidebar($index);
$content = ob_get_clean();
if (!$success) return false;
$content = art_normalize_widget_style_tokens($content);
$replaces = array(
'<!--- BEGIN Widget --->' => "<div class=\"Block\">\r\n <div class=\"Block-body\">\r\n",
'<!--- BEGIN WidgetTitle --->' => "<div class=\"BlockHeader\">\r\n <div class=\"header-tag-icon\">\r\n <div class=\"BlockHeader-text\">\r\n",
'<!--- END WidgetTitle --->' => "\r\n </div>\r\n </div>\r\n <div class=\"l\"></div>\r\n <div class=\"r\"><div></div></div>\r\n</div>\r\n",

'<!--- END WidgetContent --->' => "\r\n </div>\r\n</div>\r\n",
'<!--- END Widget --->' => "\r\n </div>\r\n</div>\r\n"
);
$bwt = '<!--- BEGIN WidgetTitle --->';
$ewt = '<!--- END WidgetTitle --->';
if ('' == $replaces[$bwt] && '' == $replaces[$ewt]) {
$startTitle = 0;
$endTitle = 0;
$result = '';
while (true) {
$startTitle = strpos($content, $bwt, $endTitle);
if (false == $startTitle) {
$result .= substr($content, $endTitle);
break;
}
$result .= substr($content, $endTitle, $startTitle - $endTitle);
$endTitle = strpos($content, $ewt, $startTitle);
if (false == $endTitle) {
$result .= substr($content, $startTitle);
break;
}
$endTitle += strlen($ewt);
}
$content = $result;
}
$content = str_replace(array_keys($replaces), array_values($replaces), $content);
echo $content;
return true;
}As you can probably already tell I know enough about programming concepts to kind of know what is going on, but I don't understand enough about how WordPress operates (yet!)
Thank you for taking the time to read this and let me know if I need to post additional code or need to clarify!
