How to make a php article counter?

Use PHP for Article page count - "Pages 1 2 3 4 5"

  • Hi, I need a PHP script for showing "Pages 1 2 3 4" or whatever along the bottom of my articles when they are pulled from the database. So if you click on a headline and it brings up the article then I only show the first 3 paragraphs then i want down the bottom a "Pages 1 2 3 4" so people can click thru to the next page or straight to page 4 etc. The paragraph count is done by exploding the stored text at the "<br /><br />" and then counting the array. $article = explode("<br /><br />", $content); $countparagraphs = sizeof($article); To keep things tidy I want the count to check if there is just one more paragraph for the next page then make the current page show four paragraphs rather than have three paragraphs and have to click one more page that would just be the last page of a four paragraph article. So it must check that if the remainder is only one then just add that to the last page. So if the paragraph count was seven you would not have 3 pages with 3 paragraphs, 3 paragraphs and 1 paragraphs you would have 3 paragraphs and 4 paragraphs (eg two pages) and so on. // Set number of paragraphs per page $num = 3; Also the current page number should not be a link...so if current page is two then Page 2 should be unlinked as it is the current page. Think it is simple but the extra paragraph thing is getting me bad :))

    Hello Srv, Here's the index.php: ----- <? if ( !isSet($currentPage) ) { $currentPage = 1; } $currentPage--; $content = ""; $content .= "This is paragraph 1<br /><br />"; $content .= "This is paragraph 2<br /><br />"; $content .= "This is paragraph 3<br /><br />"; $content .= "This is paragraph 4<br /><br />"; $content .= "This is paragraph 5<br /><br />"; $content .= "This is paragraph 6<br /><br />"; $content .= "This is paragraph 7<br /><br />"; $content .= "This is paragraph 8<br /><br />"; $content .= "This is paragraph 9<br /><br />"; $content .= "This is paragraph 10<br /><br />"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Pages</title> </head> <body> <div class="content"> <? $pPerPage = 3; $pages = split("<br /><br />", $content); if ( count($pages) > $pPerPage * 2 ) { $pageMax = 0; $pCount = 0; $thisContent = array(); for ($i = 0; $i < count($pages); $i++) { if ( ++$pCount == 1 && $i + $pPerPage < count($pages) ) { $thisContent[++$pageMax] = ""; } else if ($pCount == $pPerPage) { $pCount = 0; } if ($pages[$i] != "") { $thisContent[$pageMax] .= "<p>" . $pages[$i] . "</p>"; } } echo $thisContent[$currentPage + 1]; ?> </div> <p class="footer">Page | <? for ($i = 0; $i < $pageMax; $i++) { if ($i == $currentPage) { ?><span><?=$i + 1?></span> | <? } else { ?><a href="index.php?currentPage=<?=$i + 1?>"><?=$i + 1?></a> | <? } } ?> </p> <? } else { echo $content; } ?> </body> </html> ----- (Some longer lines might break up and need to be repaired in above PHP code.) Hope that helps!
