title: php mysql insert
body: <p>I am pretty new in php programming and i'm facing with one trouble here. Probably it will be simple for all of you, but ok..</p>
  
  <p>When i try to insert one row into mysql table named "novica" first time it works ok, but after that i'm unable to add any new row's. But when i delete this row, i can add one...but again, only one. I don't know what cause this.</p>
  
  <p>here is my little php:</p>
  
  <pre><code>&lt;?php
      $con = mysql_connect("localhost","root","password");
      if (!$con)
      {
          die('Could not connect: ' . mysql_error());
      }
  
      mysql_select_db("sola", $con);
      mysql_query("INSERT INTO novica (naslov, vsebina, avtor, ustvarjeno) VALUES('$_POST[address]', '$_POST[content]', 'Klemen', NOW())");
  
      mysql_close($con);
  ?&gt;
  </code></pre>
  
  <p>And here is mysql export sql code:</p>
