预期表格应如下所示：

经过检查和批准的行使用PHP代码转到postgres数据库下面是获得预期的代码表。

     <!DOCTYPE html>
     <html>
     <head>
     <script>
      function approve(tableID) {
 <?php
   //connecting to database
  $db = pg_connect("host= port=5432 dbname=NEWS user=postgres password=");
  if(!$db){
   echo "Error : Unable to open database\n";
    } else {
  echo "Opened database successfully\n";
 }
//setting default time zone
date_default_timezone_set('Asia/Kolkata');

  $chkbox = $_POST['chk'];
 foreach($chkbox as $a => $b)
 echo "$chkbox[$a]  <br />";

  var rowCount = table.rows.length;
        var row = table.insertRow(rowCount);

        var colCount = table.rows[0].cells.length;

        for(var i=0; i<colCount; i++) {

       //inserting news into database table
                                    $query = "INSERT INTO   ndem_news_table(news_link,   news_title,   news_date, news_source, news_time) VALUES('".$news_link."','".$news_title."','".$news_date."','".$dk."','".$dt."')";
                $result = pg_query($query);
                if (!$result) {
                    //$errormessage = pg_last_error();

                    //exit();
                }
                else
                {
                   echo "Row Inserted Successfully <br>";
                }
        }
  //php code to insert into data base
 }


  function delete(tableID)
 {
   echo'i am inside of delete';
       try {
                   var table = document.getElementById(tableID);
                   var rowCount = table.rows.length;

                             table.deleteRow(i);
                             rowCount--;
                             i--;
                         }          
                     }

我这里的表是硬编码的，我希望它是动态生成的，我从新闻频道的XML源获取的表数据。

我想动态地将数据插入表中，然后将所需的行发布到postgres表中，但不是全部
