我想将名为“videoarchives”的数据库中的 id-key 映射到名为 DT_RowId 的 DataTables-id。创建新行时，我希望它使用唯一的主键，并在编辑它以维护这个唯一的主键时。
我想知道我应该如何修改下面videos.php中的代码来完成这个。我在文档中找到了这个例子，使用了另一种语法。我怎样才能调整下面的代码来完成同样的事情？（http://www.datatables.net/examples/server_side/ids.html ）：
// 应读取并发送回 DataTables 的数据库列数组。//db参数代表数据库中的列名，而dt
// 参数代表 DataTables 列标识符 - 在本例中是 object // 参数名
$columns = array(
array(
'db' => 'id',
'dt' => 'DT_RowId',
'formatter' => function( $d, $row ) {
// Technically a DOM id cannot start with an integer, so we prefix
// a string. This can also be useful if you have multiple tables
// to ensure that the id is unique with a different prefix
return 'row_'.$d;
}
),
videoadmin.html 中的一些代码：
$(document).ready(function() { //fields we can add or edit ?
editor = new $.fn.dataTable.Editor( {
ajax: "../php/videos.php",
table: "#example",
idSrc: "DT_RowId",
fields: [
{
label: "Title:",
name: "videoarchives.Title"
}, {
label: "Date:",
name: "videoarchives.Date",
type: "date"
}, {
label: "VideoDescription:",
name: "videoarchives.VideoDescription"
}, {
label: "Language:",
name: "videoarchives.Language"
}, {
label: "Category:",
name: "videoarchives.Category"
}, {
label: "VideoLink:",
name: "videoarchives.VideoLink",
}, {
label: "HDLink:",
name: "videoarchives.HDLink"
},
{
label: "German title:",
name: "videoarchives_german.TitleGerman"
},
{
label: "German subtitle:",
name: "videoarchives_german.SubtitleGerman"
},
{
label: "German description:",
name: "videoarchives_german.DescriptionGerman"
}
]
} );
//oTable.fnSetColumnVis(0, false);
