Hej udviklere!
Jeg sidder og kæmper med at opdele SQL udtræk i sider. Jeg fandt et lille script på nettet, men jeg har et lille problem med det.
Jeg antager det virker fint, problemet er bare, at det ikke trækker noget ud af min database. Lad mig lige give jer scriptet, og så hvad jeg tror fejlen er!
- <?php
- include('dbopen.php'); // include your code to connect to DB.
-
- // How many adjacent pages should be shown on each side?
- $adjacents = 1;
-
- /*
- 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 texts WHERE godkendt =1";
- $total_pages = mysql_fetch_array(mysql_query($query));
- $total_pages = $total_pages[num];
-
- /* Setup vars for query. */
- $targetpage = "oversigt.php"; //your file name (the name of this file)
- $limit = 25; //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 = mysql_query("SELECT id, text, addedBy FROM texts WHERE godkendt = 1 LIMIT $start, $limit");
-
- /* Setup page vars for display. */
- if ($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\">« previous</a>";
- else
- $pagination.= "<span class=\"disabled\">« previous</span>";
-
- //pages
- if ($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\">next »</a>";
- else
- $pagination.= "<span class=\"disabled\">next »</span>";
- $pagination.= "</div>\n";
- }
- ?>
- <?php
- echo "<div class='text'>";
- echo "<table>";
- while($row = mysql_fetch_array($sql))
- {
-
- echo "<tr><td style=\"vertical-align:top;padding:15px;\" >";
- echo "<b>";
- echo "<a href='oversigt.php?page=view&id=". $row['id'] . "'>";
- echo "" . $row["text"];
- echo "</a>";
- echo "</b>";
- echo ", " . $row["addedBy"];
- echo "<br />";
- echo "</td></tr>";
- }
- echo "</table>";
-
- ?>
-
- <?php
- echo $pagination;
- ?>
Jeg gætter på, at fejlen ligger i åbningen af databasen:
- $sql = mysql_query("SELECT id, text, addedBy FROM texts WHERE godkendt = 1 LIMIT $start, $limit");
Jeg har siddet og kæmpet med det hele denne lørdag, men må give op nu, og søge hjælp herinde
På forhånd rigtig mange gange tak, og god weekend!
Rai.
