PHP - Updating A Column In A Mysql Table With Php Help Me

For the last few days I have been trying to work out why my code does not update the MySQL database table.  Having tried several variation I have the below but cannot see anything wrong. The rest of the program produces the correct results (displaying what is currently on the table) showing it is connecting to the correct table but altering the table is not working. Any help greatly appreciated.

The few lines in question a
Code: [Select]

// Update the profile data in the database
   
if (!$error) {
      if (!empty($name)&& !empty($phone) && !empty($address1) && !empty($address2)) {
        // Only set the picture column if there is a new picture
        if (!empty($new_picture)) {

//if (!empty($postcode)){
          $query = "UPDATE antique SET name = '$name', phone = '$phone', address1 = '$address1', address2 = '$address2', postcode = '$postcode', " .
            " email = '$email', webadd = '$webadd', picture = '$new_picture', username = '" . $_SESSION['username'] . "'  WHERE name = '" . $row['name'] ."'";
       
}}
       
        else {
         
$query = "UPDATE antique SET name = '$name', phone = '$phone', address1 = '$address1', address2 = '$address2', postcode = '$postcode', " .
            " email = '$email', webadd = '$webadd', username = '" . $_SESSION['username'] . "'  WHERE name = '" . $row['name'] ."'";
        }
        mysqli_query($dbc, $query) or die("<br>Query $query<br>Failed with error: " . mysqli_error($dbc) . '<br>On line: ' . __LINE__);

       

The whole program is below

Apologies... I'm a noob trying to reverse engineer code.

I have a script that can retrieve values from a MySQL database (based on a session login that recognizes which user you are) and places those values  into the text fields of a form, pre-populating the form.

Code: [Select]
<?php
mysql_connect('localhost', 'db', 'password'); 
mysql_select_db('users');

$id     =  mysql_real_escape_string($_SESSION['userid']);
$select =  "SELECT * FROM user_info WHERE md5(Member_No) = '$id';";
$query  =  mysql_query($select);
if ($row = mysql_fetch_array($query)) {
?>
<form>
FIRST name: <input type="text" name="First" value="<?php echo stripslashes($row['First']); ?>"
LAST name: <input type="text" name="Last"  value="<?php echo stripslashes($row['Last']); ?>" >
Birthday: <input type="text" name="Birthday" value="<?php echo stripslashes($row['Birthday']); ?>"
<input type="submit" value="Submit">
</form>
<?php
}
?>

I want to be able to connect to that same database and update ALL the values (3 in the example above) with the single click of the form button.  I think I was told some time ago that it's not possible to update all the values at once?

Thanks,

~Wayne

I have a user table that holds email addresses and for testing purposes I am trying to replace every email address with an email address defined in an array.  I would like to randomly choose an email address from the array and update the table with this address.  When I run the following code it randomly chooses a email address from the array but then updates every row with this one email address.  Can you someone please let me know what I am doing wrong.  Thanks in advance.

Code: [Select]
$query = "SELECT * FROM user '";
$result = mysql_query($query);

$input = array('email1', 'email2', 'email3', 'email4', 'email5', 'email6', 'email7');
$rand_keys = array_rand($input, 2);
$replaceStr = $input[$rand_keys[0]];

while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
 $rand_keys = "";
 $rand_keys = array_rand($input, 2);
 $replaceStr = $input[$rand_keys[0]];

 mysql_query("UPDATE user SET email = '$replaceStr'");

}

I have a mysql table named songs with 3 columns, id, artist,title.

Most of the songs in the artist column are correct, ex:

artist
------------------
John Denver
Loretta Lynn
Shania Twain
Luke Bryan

But some of the songs in the artist column are reveresed with a comma, ex:

artist
-----------------
Dever, John
Lynn. Loretta
Twain, Shania
Bryan, Luke

Is there an easy php code snippet or mysql statement that i can use to reverse the order of first name and last name and remove the comma in the last example so the artst columd matches the first example?

I hope this makes sense, thanks, Dale.

I have a table of restaurant menu items called menu_items.  This table has a float row(3,2) called price.  I have a query that looks like this:

$query = mysql_query("SELECT * FROM menu_items WHERE restaurant = '".$restaurantid."'");

How would I find the average of the price row from that query?  Basically I want to find the average item price for a restaurants menu.
