我正在使用 jQuery DataTables插件来显示由多个表组合而成的一组结果。我正在尝试通过插件实现服务器端处理以改善页面加载时间。我无法完全弄清楚如何将DataTables 提供的示例外推到我的场景中。有什么想法/建议吗?
Javascript:
$('#results').dataTable({
"sAjaxSource": "../server_processing.php",
"bProcessing": true,
"bServerSide": true,
"bDeferRender": false,
})
原始PHP函数:
function build_data_list(){
global $org_id;
global $dbh;
global $req_ids;
global $user_list;
$sth = $dbh->query ("SELECT
l4.name as L4name,
l3.name as L3name,
l2.name as L2name,
l1.name as L1name,
u.id,
u.last_name,
u.first_name,
FROM user_grp_indx ugi, groups l4, groups l3, groups l2, groups l1, users p
WHERE
ugi.user_id = u.id
AND l4.id = ugi.grp_id
AND l4.parent = l3.id
AND l3.parent = l2.id
AND l2.parent = l1.id
ORDER BY u.id", PDO::FETCH_ASSOC);
$row = $sth->fetch();
$item['user_id'] = $row['id'];
$item['user_info'] = '<a href="../users/index.php?pq=';
$item['user_info'] .= $row['id'].'">';
$item['user_info'] .= $row['last_name']. ", " . $row['first_name'] . "</a>";
$item['l1_name'] = $row['L1name'];
$item['l2_name'] = $row['L2name'];
$item['l3_name'] = $row['L3name'];
$item['l4_name'] = $row['L4name'];
for ($i=0; $i < sizeof($req_ids) ; $i++ ){
$item['req'.$i] = (chk_req_status($item['user_id'],$req_ids[$i]) ? "<span title=\"Yes\"></span><img src=\"../../media/icons/tick.png\" alt=\"Yes\" />" :
"<span title=\"No\"></span><img src=\"../../media/icons/cross.png\" alt=\"No\" />");
}
$old_L1id = $row['L1id'];
$old_user_id = $row['id'];
while ($row = $sth->fetch()){
$L1id = $row['L1id'];
$user_id = $row['id'];
if ($L1id == $old_L1id && $user_id == $old_user_id ){
$item['l2_name'] .= "<br/>" . $row['L2name'];
$item['l3_name'] .= "<br/>" . $row['L3name'];
$item['l4_name'] .= "<br/>" . $row['L4name'];
continue;
}
$user_list[] = $item;
$old_L1id = $L1id;
$old_user_id = $user_id;
$item['user_id'] = $row['id'];
$item['user_info'] = '<a href="../users/index.php?pq=';
$item['user_info'] .= $row['id'].'">';
$item['user_info'] .= $row['last_name']. ", " . $row['first_name'] . "</a>";
//add inital level stuff to the new record.
$item['l1_name'] = $row['L1name'];
$item['l2_name'] = $row['L2name'];
$item['l3_name'] = $row['L3name'];
$item['l4_name'] = $row['L4name'];
for ($i=0; $i < sizeof($req_ids) ; $i++ ){
$item['req'.$i] = (chk_req_status($item['user_id'],$req_ids[$i]) ? "<span title=\"Yes\"></span><img src=\"../../media/icons/tick.png\" alt=\"Yes\" />" :
"<span title=\"No\"></span><img src=\"../../media/icons/cross.png\" alt=\"No\" />");
}
}
}
原始 HTML/PHP:
<tbody>
<?php foreach($user_list as $item){
print "<tr>";
print "<td class=\"hidden\">{$item['user_id']}</td>";
print "<td>{$item['user_info']}</td>";
print "<td>{$item['l1_name']}</td>";
print "<td>{$item['l2_name']}</td>";
print "<td>{$item['l3_name']}</td>";
print "<td>{$item['l4_name']}</td>";
for ($i=0; $i < sizeof($req_ids) ; $i++ ){
print '<td>'.( chk_req_status($item['user_id'],$req_ids[$i]) ? "<span title=\"Yes\"></span><img src=\"../../media/icons/tick.png\" alt=\"Yes\" />":
"<span title=\"No\"></span><img src=\"../../media/icons/cross.png\" alt=\"No\" />").'</td>';
}
print "</tr>";
} ?>
