I can't get my update query to work (php / mysqli) - php

Question

I am posting a shortened version of the form and updating lines. I will truly appreciate any help. I have spent the last 48 hours trying all I could think of and it's driving me insane. If I remove the line if($_SERVER["REQUEST_METHOD"]=="POST"), the program runs on loading the page and does update the table at the ID in the url with a blank field. Thanks in advance. Here's the code:
<?php
$id = $_GET['id'];
$user = $_SESSION['user'];
Echo '<form action="editone.php" method="POST">
Enter new name:<input type="text" name="namex" />
<input type="submit" name="Submit" value="Update List" /> </form>';
if($_SERVER["REQUEST_METHOD"]=="POST")
{
$dblink = "nn000185_manager";
$cxn = new mysqli("localhost","user","password", $dblink);
$details = mysqli_real_escape_string($cxn, $_POST['namex']);
$numb = mysqli_real_escape_string($cxn, $id);
$query = "UPDATE EDITORES SET nom_edit = '$details' WHERE edit_id = $numb";
mysqli_query($cxn, $query);
echo $query;
}
?>

Answer 1

I think your form action didn't pass id.
<form action="editone.php" method="POST">
If you're using this single file as form editor and action, your form editor URL should be http://localhost/editone.php?id=1
Try to change your form action to
<form action="editone.php?id='.$_GET['id'].'" method="POST">
or just leave the action blank
<form action="" method="POST">

Ok - maybe I'm way off base here but I see the following problems.
1) Your method is POST however your id is coming from GET.
2) I don't see where the id is coming from. It could be coming from somewhere and not posted but I don't see it.
Have you checked to verify the value is actually being passed through to the php?
try this
echo "GET = " . var_dump($_GET);
echo "<br><br>";
echo "POST = " . var_dump($_POST);
exit();
Post the results and then post where the id is coming from if you can't figure it out still. :)

Use the below code:
$query = "SELECT now_edit, FROM EDITORIES WHERE edit_id='$numb' LIMIT 1";

I assume your page is being called initially from an anchor link on another page which is why you are getting the id from $_GET['id'].
When the user presses the submit button of course the form is being submitted as a POST so all the data will be in $_POST, therefore $_GET['id'] will fail and should be generating an error message.
You need to save the $_GET['id'] from the first instantiation so you can use it when the form is posted to you. So put it in a hidden field that will be posted to you with the post
<?php
session_start();
$user = $_SESSION['user'];
if($_SERVER["REQUEST_METHOD"]=="GET") {
if ( isset($_GET['id']) ) {
$id = $_GET['id']);
} else {
// no param passed, could be a hack
header('Location: some_error_page.php');
exit;
}
echo '<form action="editone.php" method="POST">';
echo '<input type="hidden" name="id" value="' . $id . '">';
echo 'Enter new name:<input type="text" name="namex" />';
echo '<input type="submit" name="Submit" value="Update List" /></form>';
}
if($_SERVER["REQUEST_METHOD"]=="POST") {
$dblink = "nn000185_manager";
$cxn = new mysqli("localhost","user","password", $dblink);
$details = mysqli_real_escape_string($cxn, $_POST['namex']);
$numb = mysqli_real_escape_string($cxn, $_POST['id']);
$query = "UPDATE EDITORES SET nom_edit = '$details' WHERE edit_id = $numb";
mysqli_query($cxn, $query);
echo $query;
}
?>
