没有错误，sql是正确的，表未更新

Question

I'm trying to update my database via a simple form and for some reason, the table doesn't update. I tried the sql query inside phpmyadmin and it seemed to work fine.

     <?php 
include("_/inc/session_handler.php");
include("_/inc/dbcon.php");
$uplform = "";

if(isset($_POST['insert'])){
    $post=$_POST['wish'];
    $succes="";
    $succes .="<h1>SUCCES</h1>";
    $insert_wish_sql="INSERT INTO wishlist(wish_id, wish, datetime)VALUES (null, '$post', CURDATE())";//insert new post
    echo $succes;
}



//The form

$uplform .="<form action=\"\"method=\"post\">";
$uplform .="<input type='text' name='wish' placeholder='wish'/>";
$uplform .="<input type=\"submit\" name=\"insert\" value=\"Upload\" />";
$uplform .="</form>";

?>

i even get the succes message, but nothing happens in the table. what am i missing?

UPDATE: I just went fully retarded. i forgot to add

$link = mysql_connect($host, $login, $pw);
    mysql_select_db($database);

so i was basically not connected to the database 8-|. Thanx a lot!

Answer 1

There may be one problem looking at your code is that it is not executed. SO execute it like this

 $res = mysqli_query($conn, $insert_wish_sql);

But the bigger concern is your sql itself as you are passing null as the value for id. Is your id is not primary or auto increment. If it is then it will fail always.

Answer 2

I miss your connection to a database server ( I guess its' that include) and finally if a connection exits, you need to send/execute your query.

The API's: PDO or mysqli is good for it.

or to test stuff, with the mysql API ( but I would not recommend it to use it live) http://ch1.php.net/manual/en/book.mysql.php
