PHP脚本不更新MySQL行

Question

I'm trying to update a row in my database but it's not running.

Below is the current script I have that gets values from an ajax call. I've checked the call and it is sending the right information. know that I do have the connection values at the top of the script but did not include them here.

// Opens a connection to a MySQL server
$connection = mysql_connect($host, $username, $password);
   if (!$connection) {
 die("Not connected : " . mysql_error());
}   // Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
  if (!$db_selected) {
die("Can\'t use db : " . mysql_error());
}
// Store INFORMATION

    $name = $_POST['name'];
    $website = $_POST['website'];
    $address = $_POST['address'];
    $request_url = $base_url . "&q=" . urlencode($address);
    $csv = file_get_contents($request_url) or die("url not loading");
    $csvSplit = split(",", $csv);
    $status = $csvSplit[0];
    $lat = $csvSplit[2];
    $lng = $csvSplit[3];
    $state = $_POST['state'];
    $ident = $_POST['ident'];
 $query = "UPDATE  markers SET  name =  '".$name."', website =  '".$website."',address =  '".$address."',lat =  '".$lat."',lng =  '".$lng."',state =  '".$state."'WHERE id = '" . $ident . "'";
  mysql_query($query) or die(mysql_error());

?>

I'm still very new at this, can someone explain why it's not working?

Answer 1

您应该在该引号中添加字段名称，例如名称，网站等：`并且您应该仅在单词之间使用一个空格，并且可能在WHERE之前添加一个空格。

Answer 2

您需要在“ where”之前添加空间

Answer 3

If your id field is a number, you shouldn't be quoting the value you're comparing to, here:

WHERE id = '" . $ident . "'";

Just do this:

WHERE id = " . $ident;

One often overlooked test to to have your script echo out the actual query that's being run, and then take that query string and run it directly against the database server - in your case, in phpMyAdmin against your MySQL server.
