  //edit.php

  Edit an entry

  $database = "sunsite";

  $tablename = $_REQUEST['tablename'];

  echo "

  Data from $tablename

  ";

  mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");

  $query = "show columns from $tablename";

  $result = mysql_db_query($database,$query);

  $column = 0;

  if ($result)

  {

  echo "Found these entries in the database:

  ";

  echo "";

  while ($r = mysql_fetch_array($result))

  {

  echo "$r[0]";

  $colname[$column] = $r[0];

  $column = $column + 1;

  }

  echo "

  ";

  mysql_free_result($result);

  $query = "select * from $tablename";

  $result = mysql_db_query($database, $query);

  if ($result)

  while ($r = mysql_fetch_array($result))

  {

  echo "";

  echo "$r[0]";

  for($col=1;$col<$column;$col++) echo "$r[$col]";

  echo "

  ";

  }

  echo "";

  }

  else echo "No data.";

  mysql_free_result($result);

  ?>

  ">Finish

  然后选择其中一个id,会跳出具体的内容并要求用户修改。

  //editing.php

  Editing an entry

  $database = "sunsite";

  $tablename = $_GET['tablename'];

  mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");

  $query = "show columns from $tablename";

  $result = mysql_db_query($database,$query);

  $column = 0;

  if ($result)

  {

  while ($r = mysql_fetch_array($result))

  {

  $colname[$column] = $r[0];

  $column = $column + 1;

  }

  mysql_free_result($result);

  }

  $temp = $_GET[$colname[0]];

  $query = "select * from $tablename where $colname[0]=$temp";

  $result = mysql_db_query($database,$query);

  $r = mysql_fetch_array($result);

  ?>

  :

  for ($col=1;$col<$column;$col++)

  echo "$colname[$col]:

  ";

  ?>

  ">

  ">

  最后是写入数据库

  //editdb.php

  $database = "sunsite";

  $tablename = $_POST['tablename'];

  mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");

  $query = "show columns from $tablename";

  $result = mysql_db_query($database,$query);

  $column = 0;

  if ($result)

  {

  while ($r = mysql_fetch_array($result))

  {

  $colname[$column] = $r[0];

  $column = $column + 1;

  }

  mysql_free_result($result);

  }

  for($col=0;$col<$column;$col++)

  $para[$col] = $_POST[$colname[$col]];

  if ($_POST['name'])

  {

  mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");

  $query = "update $tablename set $colname[1]='$para[1]'";

  for($col=2;$col<$column;$col++)

  $query = $query . ",$colname[$col]='$para[$col]'";

  $query = $query . " where $colname[0]='$para[0]';";

  $result = mysql_db_query($database, $query);

  Header("Location: edit.php?tablename=$tablename");

  }

  else

  {

  echo "No name Entered. Please go back and reenter name";

  }

  ?>

  待续。
