分页段落-每页显示一定数量的段落

Posted 2021-02-26

I wrote this really quick and dirty script to paginate a very large chunk of text. A client site was setup with the understanding their about page would consist of 5-6 paragraphs but their biography ended up being 60 paragraphs. At the end of the day instead of breaking segments out into separate pages as stored in the database I kept it intact (including the way they edit it in the CMS) but this simple function paginates it only showing a certain number of paragraphs at a time.

Please email code -at- aristoworks.com if you need some clarification on how to use this.

function paraPag($data) {
 
		$chars = "<p> </p>"; // CHARACTERS TO REMOVE FROM LEFT AND RIGHT OF ORIGINAL TEXT
 
		$text = trim($data, $chars);
 
		$delimiter = "<br /><br />"; // COULD BE <BR><BR>, 

, 
 OR ANYTHING THAT APPEARS BETWEEN YOUR PARAGRAPHS
 
		$paragraphs = explode($delimiter, $text);
 
		$count = count($paragraphs); // GET THE COUNT OF PARAGRAPHS
 
		$num_page = 10; // THE NUMBER OF PARAGRAPHS YOU WANT DISPLAYED ON EACH PAGE
 
		$pages = ceil($count / $num_page);  // GET THE NUMBER OF PAGES TOTAL
 
		$output = ''; // INITIATE THE VARIABLE
 
			// SET THE PAGE NUMBER
			if(isset($_GET['page'])) {
				$page = $_GET['page'];
			} else {
				$page = 1;
			}
 
			$start = ($page * $num_page) - $num_page;
 
			$end = ($page * $num_page) - 1;
 
			// PRINT THE PAGE CONTENTS
			for($i=$start; $i<=$end; $i++) {
 
				if($i< $count) {					
				$output .= "<p>".$paragraphs[$i]."</p>
";
				}
 
			}
 
			// PRINT OUT THE PAGE NUMBERS
			for($i=1; $i<=$pages; $i++) {
 
			if($i == $page) {
				$class = "class="activePage"";
			} else {
				$class = 'class="page"';
			}
 
			$output .= "<a $class href="?page=$i">$i</a> ";
 
			}
 
			return $output;
 
	}
