我正在尝试使用可在DataTables Data Manager (CRUD) Add-on
上找到的DataTables（CRUD）插件到目前为止，除非我尝试添加新记录，否则一切正常。 我已按照此链接Adding Records和WiKi Example
上的示例说明进行操作这是我用来插入新记录的代码
// Open the db connection
$link = dbConnect('dbname');
$params = array();
$options = array( "Scrollable" => SQLSRV_CURSOR_KEYSET );
// Prepare the insert
$updateQuery = "INSERT INTO $tblname ($columns) VALUES ($valuesTemp)";
$id = 0;
$entity_id = array();
// Run the insert and if it's been succesful enter the if condition
if(sqlsrv_query( $link, $updateQuery ) == true){
// Get the last inserted ID
$getId = "SELECT MAX(Entity_Id) AS 'Id' FROM HoldingTable WHERE Client_Id = '$client_id' AND Project_Id = '$project_id'";
$result = sqlsrv_query( $link, $getId, $params, $options );
while ( $aRow = sqlsrv_fetch_array( $result, SQLSRV_FETCH_NUMERIC ) )
{
$entity_id = $aRow;
}
$id = $entity_id[0];
// Close the connection.
sqlsrv_close( $link );
// return the id
echo $id;
}else{
// If the insert failed display an error
echo 'There\'s been an error: ';
if( ($errors = sqlsrv_errors() ) != null) {
foreach( $errors as $error ) {
echo "SQLSTATE: ".$error[ 'SQLSTATE']."<br />";
echo "code: ".$error[ 'code']."<br />";
echo "message: ".$error[ 'message']."<br />";
}
}
}
如果运行firebug并检查网络，我会正确获取数字ID，就像网站上的示例一样，但是在插入后尝试刷新表时，我仍然收到一条弹出消息，出现以下错误。
DataTables warning (table id = 'dataTable'): Requested unknown parameter 'Entity_Id' from the data source for row 2 (This number changes depending on how many rows I've got)
该消息有两个记录，插入第三个记录后。
我已经尝试移动在插入之前获取id的select，但仍然会得到相同的错误并且无法找出原因。
这是DataTables的初始化：

我还没有找到解决方案。我一直在谷歌搜索和大多数帖子谈论JSON中的空值，所以我修改了aoColumns并添加了这个sDefaultContent：“”有空值而不是空值。但我仍然得到同样的错误。
答案 0 :(得分：0)
似乎JSON出现了问题。
我已经为aoColumns中的每个列声明添加了sDefaultContent：“”，现在错误已经消失。
所以我的aoColumns现在看起来像这样
"aoColumns": [
{ "mDataProp": "checkbox" ,"bSortable":false ,sDefaultContent:"", "sWidth" : "1%"},
