doddsey_65 Posted March 7, 2011 Share Posted March 7, 2011 your form method is POST so it should be $_POST['idMembers'] Quote Link to comment Share on other sites More sharing options...
lastvision Posted March 7, 2011 Author Share Posted March 7, 2011 I tried that but still got the error: Notice: Undefined index: idmembers in C:\Users\su08danielc\Documents\Website\yts\edit_user.php on line 4 Quote Link to comment Share on other sites More sharing options...
doddsey_65 Posted March 7, 2011 Share Posted March 7, 2011 try using the disabled tag properly. Eg: instead of this: <input type="text" value="<?php echo $id;?>" name="idmembers" disabled/> use this: <input type="text" value="<?php echo $id;?>" name="idmembers" disabled="disabled" /> Quote Link to comment Share on other sites More sharing options...
silkfire Posted March 7, 2011 Share Posted March 7, 2011 Check to see if $_POST is set; idmembers does not exist until your web site has been submitted/posted. Quote Link to comment Share on other sites More sharing options...

doddsey_65 Posted March 7, 2011 Share Posted March 7, 2011 can you show how you modified edit_user.php as the error jumped from line 3 to 4 Quote Link to comment Share on other sites More sharing options...
lastvision Posted March 7, 2011 Author Share Posted March 7, 2011 can you show how you modified edit_user.php as the error jumped from line 3 to 4 <?php include_once "../yts/inc/connect.php"; print_r($_POST); $id = $_POST['idmembers']; $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; $sql = "UPDATE Members SET username = '$username', password = '$password', email = '$email' WHERE Members . idmembers = '$id' LIMIT 1"; mysql_query($sql) or die ("Error: ".mysql_error()); echo "User Updated. <a href='test.php'> Return to Edit Info</a>"; ?> Quote Link to comment Share on other sites More sharing options...
doddsey_65 Posted March 7, 2011 Share Posted March 7, 2011 print_r($_POST); what does that show? Quote Link to comment Share on other sites More sharing options...
lastvision Posted March 7, 2011 Author Share Posted March 7, 2011 print_r($_POST); what does that show? It just display the information about the variable $_POST. Quote Link to comment Share on other sites More sharing options...
lastvision Posted March 7, 2011 Author Share Posted March 7, 2011 I have solved it now, made a mistake with the isset code So the code that is working is edit_user.php <?php include_once "../yts/inc/connect.php"; print_r($_POST); if(isset($_POST['idmembers'])){ $id = $_POST['idmembers']; $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; $sql = "UPDATE Members SET username = '$username', password = '$password', email = '$email' WHERE Members . idmembers = '$id' LIMIT 1"; mysql_query($sql) or die ("Error: ".mysql_error());} echo "User Updated. <a href='test.php'> Return to Edit Info</a>"; ?> Quote Link to comment Share on other sites More sharing options...
lastvision Posted March 7, 2011 Author Share Posted March 7, 2011 now i got another problem, it won't update the database, and i don't know how to fix it Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted March 7, 2011 Share Posted March 7, 2011 You haven't fixed the original problem at all. The actual problem here is that the value of a field that has the "disabled" attribute does not get sent in the $_POST array. By enclosing the entire query in the if( isset($_POST['idmembers']) ) {} conditional, all you've done is prevent the query from being reached and executed. Change the form field to use the readonly attribute instead of disabled. Quote Link to comment Share on other sites More sharing options...
kenrbnsn Posted March 7, 2011 Share Posted March 7, 2011 When you use the "disabled" attribute in a form, that value is not returned to the processing script. If you don't want the user to change the value, you can use either the "readonly" or "hidden" attribute. Ken Quote Link to comment Share on other sites More sharing options...
