Question

Hallo Ich habe folgenden Code mit Seriennummer. und Seitenumbruch. Paginierung funktioniert, aber wenn ich zur nächsten Seite gehe, dann beginnt die Seriennummer von 1. Ich habe 10 Zeilen auf jeder Seite begrenzt, also möchte ich die nächste Seite von SN beginnen. 11-20, 21-30 von der 3. Seite. Bitte hilf mir.

$sn=$start; 
 

 
if(isset($_GET['mainmdsid']))

\t $mainmdsid=$_GET['mainmdsid']; 
 
\t $start=($mainmdsid-1)*$limit; 
 
} 
 
else{ 
 
\t $mainmdsid=1; 
 
} 
 
\t $result = mysqli_query($mysqli, "SELECT *from item , mainmds , school WHERE empid=$empid AND mainmds.itmid=item.itmid AND mainmds.scid=school.scid LIMIT $start, $limit"); \t

Answer 1

nur Ihre $sn Initialisierung bewegen, nachdem wenn Bedingung

$start=0; 
$limit=10; 

if(isset($_GET['mainmdsid'])) 
{ 
    $mainmdsid=$_GET['mainmdsid']; 
    $start=($mainmdsid-1)*$limit; 
} 
else{ 
    $mainmdsid=1; 
} 
$sn=$start; 

Answer 2

Änderung dieser Code ... es

<?php include_once("../database/config.php"); 

    $start=0; 
    $limit=10; 

    if(isset($_GET['mainmdsid'])) 
    { 
     $mainmdsid=$_GET['mainmdsid']; 
     $start=($mainmdsid-1)*$limit; // here we are multiplying page number with limit. 
    } 

    $sn=$start; 

    if(isset($_GET['mainmdsid'])) 
    { 
     $mainmdsid=$_GET['mainmdsid']; 
     $start=($mainmdsid-1)*$limit; 
    } 
    else{ 
     $mainmdsid=1; 
    } 
      $result = mysqli_query($mysqli, "SELECT *from item , mainmds , school WHERE empid=$empid AND mainmds.itmid=item.itmid AND mainmds.scid=school.scid LIMIT $start, $limit");

Answer 3

Auf klicken Aus jeder arbeiten nächste Seite, erhöhen Sie die Grenze von $start von 0 bis +10. und rufen Sie erneut Ihre DB-Abfrage, und für vorherige Taste Dekrement-Wert von $start bis -10. Und verwenden Sie auch die Variable currentPage und setzt den Wert auf 1 beim Start.

Hier ist Beispielcode, die Sie verwenden können:

$currentPage = 1; 
$start = 0; 
$recordPerPage= 10; 

//First query your database here, after that do some work on previous and next button clicked 

if(array_key_exists('next',$_POST)){ 
    $start = (currentPage * recordPerPage) + 1; 
    currentPage++; 
} 
if(array_key_exists('previous',$_POST)){ 
    if (currentPage == 2) { 
     offSet = 0; 
     currentPage--; 
    } else { 
     offSet = offSet - recordPerPage; 
     currentPage--; 
    } 
} 

Auf diese Weise können Sie die aktuelle Seite, zu begrenzen und Offset behandeln. Denken Sie daran, DB Query auf nächste und vorherige Schaltfläche geklickt
