Question

我第一次使用jqgrid插件。一切都很好，除了网格从这里开始时没有加载的数据：http://imageshack.us/photo/my-images/16/capturadepantalla201305r.png“grid”。数据从数据库中获取，但只有在我点击任何标题/分类器时，它才会加载我的所有数据。我如何修复，从一开始就加载？我是一个完全的菜鸟，并希望任何帮助你们这是我的代码：

我的PHP加载：

// Get the requested page. By default grid sets this to 1. 
$page = $_GET['page']; 

// get how many rows we want to have into the grid - rowNum parameter in the grid 
$limit = $_GET['rows']; 

// get index row - i.e. user click to sort. At first time sortname parameter -
// after that the index from colModel 
$sidx = $_GET['sidx']; 

// sorting order - at first time sortorder 
$sord = $_GET['sord']; 

// if we not pass at first time index use the first column for the index or what you want
if(!$sidx) $sidx =1; 

// connect to the MySQL database server 
$db = mysql_connect($dbhost, $dbuser, $dbpassword) or die("Connection Error: " . mysql_error()); 

// select the database 
mysql_select_db($database) or die("Error connecting to db."); 

// calculate the number of rows for the query. We need this for paging the result 
$result = mysql_query("SELECT COUNT(*) AS count FROM demo"); 
$row = mysql_fetch_array($result,MYSQL_ASSOC); 
$count = $row['count']; 

// calculate the total pages for the query 
if( $count > 0 && $limit >5) { 
              $total_pages = ceil($count/$limit); 
} else { 
              $total_pages = 5; 
} 

// if for some reasons the requested page is greater than the total 
// set the requested page to total page 
if ($page > $total_pages) $page=$total_pages;

// calculate the starting position of the rows 
$start = $limit*$page - $limit;

// if for some reasons start position is negative set it to 0 
// typical case is that the user type 0 for the requested page 
if($start <0) $start = 0; 

// the actual query for the grid data 
$SQL = "SELECT id, name, id_continent, lastvisit,cdate, ddate,email FROM demo ORDER BY $sidx $sord LIMIT $start , $limit"; 
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error()); 

// we should set the appropriate header information. Do not forget this.
header("Content-type: text/xml;charset=utf-8");

$s = "<?xml version='1.0' encoding='utf-8'?>";
$s .=  "<rows>";
$s .= "<page>".$page."</page>";
$s .= "<total>".$total_pages."</total>";
$s .= "<records>".$count."</records>";

// be sure to put text data in CDATA
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
    $s .= "<row id='". $row['id']."'>";  
        $s .= "<cell>". $row['id']."</cell>";
        $s .= "<cell><![CDATA[". $row['name']."]]></cell>";
    $s .= "<cell><![CDATA[". $row['id_continent']."]]></cell>";
    $s .= "<cell>". $row['lastvisit']."</cell>";
    $s .= "<cell>". $row['cdate']."</cell>";
    $s .= "<cell>". $row['ddate']."</cell>";
    $s .= "<cell><![CDATA[". $row['email']."]]></cell>";
    $s .= "</row>";
}
$s .= "</rows>"; 

echo $s;
?>

Answer 1

我明白了。我的排序名称错了。 sortname：'invid'，它应该是“id”。感谢

jqgrid没有在开始时加载。如何在网格加载时加载数据？
