Question

So I’m really really really new to PHP and MySQL (just started today!).

I have a page that updates a MySQL database based on results from a post.

The way I have it now, the PHP code is on the page, and it works, but the problem is that it goes through on page load as well, that is, before the POST happens.

Any way to prevent this?

Here’s my code:

        <?php
            //do stuff

            // see if any rows were returned
            if (mysql_num_rows($result) > 0) {

                $row = mysql_fetch_row($result);

                while($row = mysql_fetch_row($result)) {
//do something
                  }
            }
            else {
//do something else
            }

            // free result set memory
            mysql_free_result($result);
            $first = 0;
        ?>
        <br />
        <br />

          <div id="addName">  
            <h3 class="caps">Want to add yourself?</h3>  

            <div class="box">  

            <br /> <br />
            <form id="form1" name="form1" method="post" action="#">

            Email:
            <label>
            <input type="text" name="email" id="email" />
            </label>

              <label>
              <input type="submit" name="submit" id="submit" value="Submit" />
              </label>

            </form>
            </div>  

          </div>  

        </div>  

See, problem is that it will run //do something else before the form is filled out. Any suggestions?

Thanks!

Better Condition

if(isset($_POST['submit']) && !empty($_POST) ){
  // now do with your post data
}

this will prevent empty data to be posted
