Update 1 column of all rows in the database table

Question

Hopefully someone can help me with this " easy " question.

I have data in a table that has been gathered from a mysql database. I want the user to be able to edit the "PRICE" column to any and all rows, then press the update button which will send the data to the table and update all the rows in the "PRICE" column.

For the life of me I can't get the database to update. I know it has to be something that I'm missing. And it has to be something so easy it's laughable.

Please help?

if (isset($_POST['update']))
  {
  echo '<pre>';
  print_r($_POST);
  echo '</pre>';
  if (is_array($ID))
    {
    foreach($_POST['hidden'] AS $ID)
      {
      echo "ID is: " . $ID . "</br>";
      echo "Price is: " . $pricing . "</br>";
      $ID = mysqli_real_escape_string($conn, $_POST['hidden'][$ID]);
      $pricing = mysqli_real_escape_string($conn, $_POST['price'][$ID]);
      $updateQuery = 'UPDATE `bathroom_price` SET `price` ="' . $pricing . '" WHERE `ID`=' . $ID;
      mysqli_query($conn, $updateQuery) or die(mysql_error());
      }
    }
  }

?>

<?php
mysqli_select_db($conn, "table_name");

Answer 1

Maybe this is a problem:

<input type=hidden name="hidden[]<?echo $ID ?>" value="<?echo $ID ?>" />

Your input name is "hidden[]1" etc.
