title: PHP/MYSQL - checking user identification from DB info
body: <p>So, i am making kind of a blog system for my site, and i have 2 tables. One for storing users, their passwords and images (URLs), another for storing all the blog posts, with image_url, author, date and content.
  The relevant part of my HTML is:</p>
  
  <pre><code>&lt;form action="../scripts/send.php" method="post"&gt;&lt;input type="text" name="author" placeholder="Your name" style="width:30%;"/&gt;&lt;input type="password" name="pass" placeholder="Password" style="width:30%;"/&gt;&lt;br /&gt;&lt;input type="text" name="title" placeholder="Post Title" style="width:60%;" /&gt;&lt;br /&gt;&lt;textarea name="content" rows="20" style="width:60%;"&gt;&lt;/textarea&gt;&lt;br /&gt;&lt;button &gt;Post&lt;/button&gt;&lt;/form&gt;
  </code></pre>
  
  <p>And my PHP code (send.php) is:</p>
  
  <pre><code>&lt;?php
  mysql_connect("localhost","kroltan","eclipsepdt123") or die("Can't connect to DB");
  mysql_select_db("kroltan_main") or die("Can't select to DB");
  $result = mysql_query("SELECT * FROM `users`") or die("Can't fetch data");
  if(mysql_num_rows($result) &gt; 0){
      while($row = mysql_fetch_assoc($result)){
          if ($row['name'] == strtolower($_POST['author'])){
              if ($row['pass'] == strtolower($_POST['pass'])){
                  $name = $_POST['name'];
                  $comm = $_POST['comment'];
                  $result = mysql_query("INSERT INTO blog_posts (img_url, author, title, content) VALUES(".$row['img'].", ".$_POST['author'].", ".$_POST['title'].", ".$_POST['content'].")") or die("Can't send data");
                  header("Location: /?/=Talk");
              }
          }
      }
  }
  ?&gt;
  </code></pre>
  
  <p>When i try to create a new post on the site, it does not work. I am not even redirected to the page</p>
