jamesjmann Posted February 3, 2011 Share Posted February 3, 2011 Sorry to bug yalls with yet another problem, but I tried applying pagination to the page I use to display the news on my website, which is stored within mysql, and I'm having major issues. Here's the code below for both the pagination and getting the news out of the database to display. Not sure what's going on here. I tested the script and it does everything fine except it doesn't display the information stored within the database. Go here to see for yourself: http://www.djsmiley.net/index.php <?php /* Place code to connect to your DB here. */ include('cms/news/dbconnect.php'); // include your code to connect to DB. $tbl_name="mynews"; //your table name // How many adjacent pages should be shown on each side? $adjacents = 3; /* First get total number of rows in data table. If you have a WHERE clause in your query, make sure you mirror it here. */ $query = "SELECT COUNT(*) as num FROM $tbl_name"; $total_pages = mysql_fetch_array(mysql_query($query)); $total_pages = $total_pages[num]; /* Setup vars for query. */ $targetpage = "index.php"; //your file name (the name of this file) $limit = 1; //how many items to show per page $page = $_GET['page']; if($page) $start = ($page - 1) * $limit; //first item to display on this page else $start = 0; //if no page var is given, set start to 0 /* Get data. */ $sql = "SELECT 10 FROM $tbl_name LIMIT $start, $limit"; $result = mysql_query($sql); /* Setup page vars for display. */ if ($page == 0) $page = 1; //if no page var is given, default to 1. $prev = $page - 1; //previous page is page - 1 $next = $page + 1; //next page is page + 1 $lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up. $lpm1 = $lastpage - 1; //last page minus 1 /* Now we apply our rules and draw the pagination object. We're actually saving the code to a variable in case we want to draw it more than once. */ $pagination = ""; if($lastpage > 1) { $pagination .= "<div class=\"pagination\">"; //previous button if ($page > 1) $pagination.= "<a href=\"$targetpage?page=$prev\"><img class=\"fltlft2\" src=\"http://www.djsmiley.net/images/Icons/Arrows/Previous.png\" height=\"25\" width=\"25\"></a>"; else $pagination.= "<span class=\"disabled\"><img class=\"fltlft2\" src=\"http://www.djsmiley.net/images/Icons/Arrows/Previous.png\" height=\"25\" width=\"25\"></a></span>"; //pages if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up { for ($counter = 1; $counter <= $lastpage; $counter++) { if ($counter == $page) $pagination.= "<span class=\"current\">$counter</span>"; else $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>"; } } elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some { //close to beginning; only hide later pages if($page < 1 + ($adjacents * 2)) { for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++) { if ($counter == $page) $pagination.= "<span class=\"current\">$counter</span>"; else $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>"; } $pagination.= "..."; $pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>"; $pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>"; } //in middle; hide some front and some back elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2)) { $pagination.= "<a href=\"$targetpage?page=1\">1</a>"; $pagination.= "<a href=\"$targetpage?page=2\">2</a>"; $pagination.= "..."; for ($counter = $page - $adjacents; $counter <= $page + $adjacents; $counter++) { if ($counter == $page) $pagination.= "<span class=\"current\">$counter</span>"; else $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>"; } $pagination.= "..."; $pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>"; $pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>"; } //close to end; only hide early pages else { $pagination.= "<a href=\"$targetpage?page=1\">1</a>"; $pagination.= "<a href=\"$targetpage?page=2\">2</a>"; $pagination.= "..."; for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++) { if ($counter == $page) $pagination.= "<span class=\"current\">$counter</span>"; else $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>"; } } } //next button if ($page < $counter - 1) $pagination.= "<a href=\"$targetpage?page=$next\"><img src=\"http://www.djsmiley.net/images/Icons/Arrows/Next.png\" height=\"25\" width=\"25\"></a>"; else $pagination.= "<span class=\"disabled\"><img src=\"http://www.djsmiley.net/images/Icons/Arrows/Next.png\" height=\"25\" width=\"25\"></span>"; $pagination.= "</div>\n"; } ?> <?php while($row = mysql_fetch_array($result)) { echo("<p class=NewsContainer><span class=NewsID>$type</span> <font size=5>$title</font><br><br> <em>posted by <strong>$user</strong> | added on $time</em><br><br> $message<br><br> <label class=fltlft2><img src=../images/Icons/Arrows/Right.png width=20 height=20/></label><a href=$url>Read more - $url</a> <div class=newsLikeShareRate> <table width=100% border=0> <tr> <td width=3% height=21><script src=http://connect.facebook.net/en_US/all.js#xfbml=1></script> <fb:like href='$url' show_faces=true width=450 font=arial></fb:like> </td> <td width=65%><a name=fb_share id=fb_share4 type=icon_link share_url=$url>Share</a> <script src=http://static.ak.fbcdn.net/connect.php/js/FB.Share type=text/javascript></script></td> <td width=32%>Rate this article: </td> </tr> </table> </div></p><br><br>");// Your while loop here } ?> <?=$pagination?> Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/ Share on other sites More sharing options...
shlumph Posted February 3, 2011 Share Posted February 3, 2011 $sql = "SELECT 10 FROM $tbl_name LIMIT $start, $limit"; Is 10 a field in the table? What is the query when you echo that out? Have you tested it in your MySQL editor? I'd suggest triggering errors on your queries, and posting the error if anything went wrong. $result = mysql_query($sql) or trigger_error(mysql_error()); Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169565 Share on other sites More sharing options...

Pikachu2000 Posted February 3, 2011 Share Posted February 3, 2011 If `10` isn't a field in your table, that query is failing. Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169570 Share on other sites More sharing options...
jamesjmann Posted February 3, 2011 Author Share Posted February 3, 2011 If `10` isn't a field in your table, that query is failing. I tried replacing it with a field in my table, but that didn't do anything. Did I set up the pagination code correctly?

litebearer Posted February 3, 2011 Share Posted February 3, 2011 As an aside - tremendously easy to use pagination class: http://phpsense.com/php/php-pagination-script.html I use it extensively - example in use http://www.nstoia.com/sat/disp_pag/ Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169587 Share on other sites More sharing options...
Pikachu2000 Posted February 3, 2011 Share Posted February 3, 2011 You should also change: <?=$pagination?> // --- to --- <?php echo $pagination; ?> Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169610 Share on other sites More sharing options...

BlueSkyIS Posted February 4, 2011 Share Posted February 4, 2011 you store the image in a directory and store the image name and/or path in mysql. Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169656 Share on other sites More sharing options...
litebearer Posted February 4, 2011 Share Posted February 4, 2011 if you look here http://www.nstoia.com/sat/disp_pag/ and click on the 'view code' for b_view.php, you will see how easy it is to use. that sample gallery uses 3 files - b_view.php, now2. php and ps_pagination.php - all three have a 'view code' Quote Link to comment https://forums.phpfreaks.com/topic/226608-pagination-help/#findComment-1169690 Share on other sites More sharing options...
