MySQL PHP-Suche mit Paginierung

Question

Ich versuche, eine Suche nach einem Projekt zu implementieren, an dem ich gerade arbeite.Das Problem, mit dem ich konfrontiert bin, ist, dass das Suchergebnis falsch ist, wenn ich zur zweiten Seite gehe.

Hier ist das Suchformular, das sich in meiner header.php befindet

<form name="search" id="search" method="post" action="search.php">
<input type="text" tabindex="1" class="input" id="term" name="term" value=""/>
<input type="submit" tabindex="2" id="submit" value="SEARCH" />

Hier ist der PHP-Code meiner Suchseite

<?php include ('header.php'); 

$term = $_POST['term'];

    $queryn = mysql_query("select * from scripts where title like '%$term%' or discription like '%$term%' and approved='1'") or die (mysql_error());
    $search_num_rows = mysql_num_rows($queryn);
    ?>  
    <div class="cat_script_container">
    <div class="nresults">Found <?php echo $search_num_rows;?> results for "<?php echo $term;?>"</div>
    <?php   
    // 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";
    $query = "select COUNT(*) as num from scripts where title like '%$term%' or discription like '%$term%' and approved='1' order by script_id  desc";
    $total_pages = mysql_fetch_array(mysql_query($query));
    $total_pages = $total_pages['num'];

    /* Setup vars for query. */
    //$targetpage = "category-$cr[cname]-$cid.html";    //your file name  (the name of this file)
    $catn = strtolower($cr['cname']);   //Turn category name in to lowercase
    $catn = preg_replace("![^a-z0-9]+!i", "-", $catn);
    $limit = 2;                                 //how many items to show per page
    $page = $_GET['page'];

    if($page) 
        $start = ($page - 1) * $limit;          //first item to display on this page
    else

    /* Get data. */
    $sql = "select * from scripts where title like '%$term%' or discription like '%$term%' and approved='1' order by script_id  desc LIMIT $start, $limit";

    $result = mysql_query($sql);

    $next = $page + 1;                          //next page is page + 1

    $lpm1 = $lastpage - 1;                      //last page minus 1

Ich frage mich, ob es eine Möglichkeit gibt, dem Suchformular eine Aktion wie action="search.php?term=keyword" zu geben.Ich denke, wenn ich die URL so posten kann, kann ich $_GET verwenden, um den Schlüssel zu übernehmen.Wenn mir irgendjemand dabei irgendwie helfen kann, habe ich mich wirklich angeeignet.Danke im Voraus.

Answer 1

Ändere dein action zuschreiben get

<form name="search" id="search" method="get" action="search.php">

Auf diese Weise werden die Werte Ihres Formulars angehängt search.php bei der Einreichung.

Zum Beispiel:

search.php?term=the_term

Answer 2

anstelle von Inline-Papaginierungscode Sie haben eine Klasse und kann sie dann verwenden, indem Sie seine Funktionen anrufen.Auf diese Weise können Sie neu kodieren und ein besseres Programm zu programmieren.

Sie müssen nichts mit der Klasse tun, aber nur den Anruf überprüfen.

anrufen :

pager class
