Hi,
I am trying to build an update page,
I have problem in getting the vaules from the database into a textboxes so the user can see the old values,
it is my first time to do this so I don't know how:
This is my code:

<?php
$username="whatever";
$password="whatever";
$database="whatever";
mysql_connect(localhost,$username,$password);

$query=" SELECT * FROM Companies WHERE Company_id='1'";
$result=mysql_query($query);
$num=mysql_numrows($result);
mysql_close();
$i=0;
while ($i < $num) {
$Company_id=mysql_result($result,$i,"Company_id");
$Company_name=mysql_result($result,$i,"Company_name");
$City=mysql_result($result,$i,"City");
$State=mysql_result($result,$i,"State");

++$i;
}
?>

<html>

<head>

<title>Update Page</title>
</head>

<form action="updated.php" method="post">

Compnay_id <input type="text" name="ud_first" value="<? echo $Company_id; ?>"><br>
Company_name <input type="text" name="ud_last" value="<? echo $Company_name; ?>"><br>
City <input type="text" name="ud_phone" value="<? echo $City; ?>"><br>
State <input type="text" name="ud_mobile" value="<? echo $State; ?>"><br>
<input type="Submit" value="Update">
</form>
</html>

This did not work with me and don't stuck with this code, if you have better ideas or easier code it would be great,

Thank you

The problem is that mysql_numrows should have an additonal _ and that to pull rhte result values you need to use something like $row = mysql_fetch_array or mysql_fetch_assoc with the $result,

also you may want to use full tags for your echoing into your text values

Hi, I have unashamedly modified the excellent example for mysql_fetch_assoc from the php site,
note that this should retreive your data put them into values then output - I have not tested the form but the idea is there
now - if you do not have short tags enabled <? may not work - so I have used <?= which may be used as a shortcut for <?php echo the others use the unabbreviated form - which may be the only one that works.

<?php

$conn = mysql_connect("localhost", "mysql_user", "mysql_password");

if (!$conn) {
    echo "Unable to connect to DB: " . mysql_error();
    exit;
}
 
if (!mysql_select_db("mydbname")) {
    echo "Unable to select mydbname: " . mysql_error();
    exit;
}

$sql = "SELECT * FROM Companies WHERE Company_id='1'";

$result = mysql_query($sql);

if (!$result) {
    echo "Could not successfully run query ($sql) from DB: " . mysql_error();
    exit;
}

if (mysql_num_rows($result) == 0) {
    echo "No rows found, nothing to print so am exiting";
    exit;
}

// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
//       then create $userid, $fullname, and $userstatus
while ($row = mysql_fetch_assoc($result)) {
    $Company_id = $row["Company_id"];
    $Company_name = $row["Company_name"];
      $City = $row["City"];
      $State = $row["State"];
}

mysql_free_result($result);

?>

City <input type="text" name="ud_phone" value="<?php echo $City; ?>"><br>
