html table to file

[Anon]

i have pushed the limit of my newbie knowledge and need help please.

i have to output timesheet data from a flat file (text file), allow the user to change the hours worked and then save the data back to the flat file.

How can this be achieved?

i am assuming the easiest way is to display the output using an html table with a text field containing hours worked so as to allow any changes. i have achieved this using an array. see code below

this is the point where i have come unstuck. how do i get the data in the html table format back into the flat file?

any help much appreciated

NB i have to use a flat file for this project.

$salrecords = file("./salrecords.txt");
// count the number of orders in the array
$number_of_records = count($salrecords);
if ($number_of_records == 0)
{
echo "<p><strong>No salary records on file."
."Please try again later.</strong></p>";
}
echo "<table border=1>\n";
echo "<tr><th bgcolor = \"#CCCCFF\">First Name</td>
<th bgcolor = \"#CCCCFF\">Last Name</td>
<th bgcolor = \"#CCCCFF\">Hours worked</td>
<th bgcolor = \"#CCCCFF\">Week Number</td>
<tr>";

echo"<form method=post action=\" \">";
for ($i=0; $i<$number_of_records; $i++)
{
//split up each line
$line = explode( ",", $salrecords[$i] );

  echo "<tr><td>$line[0]</td>
            <td align = right>$line[1]</td>
            <td align = right><INPUT TYPE=\"text\" NAME=\"hours\" value=\"$line[2]\"></td>
            <td align = right>$line[3]</td>
       </tr>";

}
echo "</table>";
echo"</form>";

?>

When your users hit "submit" or "post" or "update" or whatever your submit button is, the text field names become variables in PHP. so the text field with the name "hours" would become the variable $hours in the php script that you named as your action (always helps if you have that defined, by the way 😛)
