This has been bugging me for 3 days now.. I'm new to this and trying to get my head round something. I have a form which involves 3 fields. Firstname, Surname, Marks. I have used a while loop to generate the table from a mysql table. I have used a text box and used the loop to call the text box after the 'ID' so each text box is named uniquely. I am then using a post method to send values to a second page which will update the 'marks' column with the value the user has just put in.. this is where I am finding my problem!
This is the initial page.
<html>
<head><title>Please Enter Your Surname</title></head>
<body>
<center>
<h2><font color=blue>Please Enter Your Surname</font></h2><p>
<form action="insert.php" method="POST">
<?php
$db = mysql_connect("localhost","root","");
if (!$db)
{
do_error("Could not connect to the server");
}
mysql_select_db("session6",$db)or do_error("Could not connect to the database");
$result = mysql_query("SELECT * FROM members ORDER BY id",$db);
$rows=mysql_num_rows($result);
if(!$rows)
{
do_error("No results found");
}
else
{
echo "<table border=3 cellspacing=1 cellpadding=1
align=center bgcolor=lightblue>\n";
echo "<caption><h2><font color=blue> Members Details
</font></h2></caption>\n";
echo "<tr><th>Member Id</th><th>Firstname</th><th>Mark</th></tr>\n";
while ($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td strong>" . $row['Id'] . "</td>";
echo "<td strong>" . $row['Firstname'] . "</td>";?>
<td strong><input type="text" name="<?php echo $row['Id']; ?>" size="20"></td>
<tr>
<?php
}
?><input type="hidden" name="no_of_rows" value="<?php echo $rows; ?>">
<?php
echo "</table>\n";
}
mysql_close($db) or do_error("Could not close connection");
function do_error($error)
{
echo $error;
die();
}
?>
<input type="submit" value="Search">
<input type="reset" value="Reset">
</form>
</body></html>
`
Then the update is done here which is where I seem to be having a problem:
<html>
<body>
<?php
$db = mysql_connect("localhost","root","");
if (!$db)
{
do_error("Could not connect to the server");
}
mysql_select_db("marks",$db)or do_error("Could not connect to the database");
$i=1;
while ($i <= $_POST["no_of_rows"])// or $_POST["No_of_Rows"] from form
{
$insertsql = "UPDATE members SET mark = " . $_POST[$i] . " WHERE Id = " . $row['Id'] . ";";
echo $_POST['$i'];
$i++;
}
?>
</body></html>
When I echo $_POST[$i'] it shows the correct values but does not update the DB, and I'm not about ready to throw my laptop in the bin! ha! I know it is prob going to be something stupid I just can't see what, so any help would be appreciated.
