我想将名为'videoarchives'的数据库中的id-key映射到名为DT_RowId的DataTables-id。当创建一个新行时，我希望它使用一个唯一的主键，并在编辑它时保留这个唯一的主键。JQuery Datatables Editor - 为每一行维护唯一的主键
我想知道我应该如何修改下面的videos.php中的代码以完成此操作。 我在文档中找到了这个例子，使用了另一种语法。我如何调整下面的代码来完成同样的事情？ （http://www.datatables.net/examples/server_side/ids.html）：
//应该读取并发送回DataTables的数据库列数组。 //该db参数表示在数据库中的列名，而dt //参数表示数据表列标识符 - 在这种情况下对象 //参数名称
$columns = array(
array(
'db' => 'id',
'dt' => 'DT_RowId',
'formatter' => function($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;
}
),
一些从videoadmin代码。 HTML：
$(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"
}
]
});
