我正在尝试使用可以在DataTables Data Manager (CRUD) Add-on 上找到的 DataTables (CRUD) 插件
到目前为止一切正常，除非我尝试添加新记录。我已按照此链接添加记录和WiKi 示例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，我会像网站上的示例一样正确获取数字 ID，但是在插入后尝试刷新表时，我不断收到一条弹出消息，并出现以下错误。
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)
该消息包含两条记录，并在插入第三条记录后。
我尝试移动使 id 在插入之前运行的选择，但仍然出现相同的错误并且无法弄清楚原因。
这是 DataTables 初始化：

我仍然没有找到解决方案。我一直在谷歌搜索，大多数帖子都在讨论 JSON 中的空值，所以我修改了 aoColumns 并添加了这个 sDefaultContent: "" 以使用空白值而不是空值。但我仍然得到同样的错误。
