PHP - Deleting Data From A File && Mysql

I have a bad way with words, so if the title doesnt make much sense nor my post, I apolagize!

But I am using a while loop and mysql_fetch_array to echo all information in a table in mysql.

With each entry, I have included a button that executes a delete query for that entry.

Code: [Select]
$delquery="DELETE FROM requests WHERE user = '".$row['user']."'";
mysql_query($delquery,$link2);
echo "<font size='19px' color='#009933'>User deleted from request database.When I click the button, the message is echod in every entry listed on the page, and nothing happens. I figured Id use delete from the username, so that way mysql will know which one to delete... but Idk when I think about it thats dumb and makes no sense. Im stuck.

This side of the application im trying to make is the admin side where I can process requests. After I process the request I delete it from the database so I know I processed it. I have no idea what query to use for this.

Anybody know how I could do this?

Thanks

but that php script above just create table of mysql below

CREATE TABLE IF NOT EXISTS `scrore_table` (
  `scores` char(3) NOT NULL default '',
  `value` float NOT NULL default '0',
  PRIMARY KEY  (`scores`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

INSERT INTO `scrore_table` (`scores`, `value`) VALUES
('GameA0', 1),
('GameA1', 1.5651),
......etc
('GameA15', 95.572);

while of my existing database table look like:

CREATE TABLE IF NOT EXISTS `scrore_table` (
  `scrore_id` int(11) NOT NULL auto_increment,
  `scrore_title` varchar(32) collate utf8_bin NOT NULL default '',
  `scores` varchar(3) collate utf8_bin NOT NULL default '',
  `decimal_place` char(1) collate utf8_bin NOT NULL,
  `value` float(15,8) NOT NULL,
  `date_updated` datetime NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`currency_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1; ;

INSERT INTO `scrore_table` (`scrore_id`, `scrore_title`, `scores`, `decimal_place`, `value`, `date_updated`) VALUES
(1, 'Game Class A0', 'GameA0', '2', 1.00000000, '2010-04-06 22:00:54'),
(2, 'Game Class A1', 'GameA1', '2', 1.52600002,  '2010-04-06 22:00:54'),
..............................etc
(14, 'Game Class A15', 'GameA15', '2', 1.13999999,  '2010-04-06 22:00:54');

as i said i newbie to php then i dont know how to modify the php code above able to automatically create the table and insert/update new fields e.g. scrore_id, scrore_title,decimal_place, date_updated also all values to my existing database

i looking for some helps and thanks in advance..

I think this is the right section to post this is in.....

Anyway.....I'm building a web site  that requires i have  functionality to upload a tab delimited file (or some file format that is easiest) via php and insert the data into MYSQL. I've searched for many third party scripts but none seem to work. So I've decided to move to the community to see if someone can give me insight on how i might accomplish this script. I have some third party scripts but I'm not sure if they'd be of any use.

Thank you kindly

I need help here. I am creating a system where the user will be able to update the product stock by uploading the stock of the products according to the id that has been assigned to the product. 
this is how my products table in  looks like in mysql database

 

I tried the code below but all i could not update my data into my database. And there's not error shown on my code. I do not know what is wrong with my codes. Please help me.
below the code that i use for uploading the CSV file to the data of my product_stock. 

<?php 
include 'conn.php';
if(isset($_POST["add_stock"]))
{
 if($_FILES['product_file']['tmp_name'])
 {
  $filename = explode(".", $_FILES['product_file']['tmp_name']);
  if(end($filename) == "csv")
  {
   $handle = fopen($_FILES['product_file']['tmp_name'], "r");
   while($data = fgetcsv($handle))
   {
    $product_id = mysqli_real_escape_string($conn, $data[0]);
    $product_stock = mysqli_real_escape_string($conn, $data[1]);  
    $product_status = 1 ;
    $query = "UPDATE products SET `product_stock` = '$product_stock', `product_status` = '$product_status' WHERE id = '$product_id'";
    mysqli_query($conn, $query);
   }
   fclose($handle);
   header("location: upload-product.php?updation=1");
  }
  else
  {
   echo '<script>alert("An error occur while uploading product. Please try again.")
   window.location.href = "upload-product.php"</script>';
  }
 }
 else
 {
  echo '<script>alert("No file selected! ")
  window.location.href = "upload-product.php"</script>';
 }
}
if(isset($_GET["updation"]))
{
  echo '<script>alert("Product Stock Updated successfully!")</script>';
}
?>

 <div class="col-12">
            <div class="card card-user">
              <div class="card-header">
                <h5 class="card-title">Update Product Stock</h5>
                <div class="card-body">

                <button type="submit" class="btn btn-primary btn-round" name="add_stock"> Import .cvs file</button>
                </div>
                </div>
                </div>
                </div>
                </form>
                </div>
              </div>

This is the template that i require user to key in and saved it in CSV format before uploading it.
