Updating contacts info in MySQL database via PHP.

[kunyomi]

Hey guys, I've just started coding php, for a school project. I'm creating a member login system with functions to add/edit contacts.

 

Currently I'm stuck at updating the contacts. I'm able to pull up data into a form in a page called 'edit.php', but after updating and clicking submit, it just returns a blank page and the SQL database is not updated.

 

This is the code from 'edit.php'.

 

<?
include ("dbConfig.php");
require ("check.php");

if($_GET["cmd"]=="edit" || $_POST["cmd"]=="edit")
{
   if (!isset($_POST["submit"]))
   {
      $id2 = $_GET["id2"];
      $sql = "SELECT * FROM contacts WHERE id2=$id2";
      $result = mysql_query($sql);        
      $myrow = mysql_fetch_array($result);
      ?>
  
      <form action="edit.php" method="post">
      <input type=hidden name="id2" value="<?php echo $myrow["id2"] ?>">
   
      Name:<INPUT TYPE="text" NAME="name" VALUE="<?php echo $myrow["name"] ?>" SIZE=30><br>
      Email:<INPUT TYPE="text" NAME="email" VALUE="<? echo $myrow["email"] ?>" SIZE=30><br>
      Who:<INPUT TYPE="text" NAME="age" VALUE="<?php echo $myrow["age"] ?>" SIZE=30><br>
      Birthday:<INPUT TYPE="text" NAME="birthday" VALUE="<? echo $myrow["birthday"] ?>" SIZE=30><br>
      Address:<TEXTAREA NAME="address" ROWS=10 COLS=30><? echo $myrow["address"] ?></TEXTAREA><br>
      Number:<INPUT TYPE="text" NAME="number" VALUE="<? echo $myrow["number"] ?>" SIZE=30><br>
   
      <input type="hidden" name="cmd" value="edit">
   
      <input type="submit" name="submit" value="submit">
   
      </form>
      
      
<? } ?>
<?
   if ($_POST["$submit"])
   {
   	  $id2 = $_POST["id2"];
      $name = $_POST["name"];
  $email = $_POST["email"];
  $age = $_POST["age"];
  $birthday = $_POST["birthday"];
  $address = $_POST["address"];
  $number = $_POST["number"];
  
  $sql = "UPDATE contacts SET name='$name',email='$email',age='$age',birthday='$birthday',address='$address',number='$number' WHERE id2=$id2";
      
      $result = mysql_query($sql);
      echo "Thank you! Information updated.";
}
}
?>

 

Please help, truly appreciated.

in the update part

u got $_POST["$submit"]

which $submit is a unset variable, it is blank

so, your actually accessing $_POST[], and this is nothing, and of course return nothing
