copied!<p>I'm new to php and I don't quite understand why this form is submitting under all circumstances... So my question is:</p> <p>How do I fix this so the form only submits when the user fills out all fields?</p> <pre><code>if (!$_POST['username'] && !$_POST['password'] && !$_POST['repassword'] && !$_POST['user_firstname'] && !$_POST['user_lastname'] ){ header('Location: register.php?msg=You did not complete all of the required fields'); } </code></pre> <p>I used both <code>&&</code> and <code>||</code> operators however it always submits no matter what field you filled out. </p> <pre><code><form action="createuser.php" method="post" name="registration_form" id="registration_form"> <label>Email</label> <input name="username" type="text" id="username" size="50" maxlength="50" /><br /> <label>First Name</label> <input name="user_firstname" type="text" id="user_firstname" size="50" maxlength="50" /><br /> <label>Last Name</label> <input name="user_lastname" type="text" id="user_lastname" size="50" maxlength="50" /><br /> <label>Password</label> <input name="password" type="password" id="password" size="50" maxlength="100" /><br /> <label>Re-type Password</label> <input name="repassword" type="password" id="repassword" size="50" maxlength="100" /><br /> <input type="submit" value="Register" name="submit" /> </code></pre> <p>Thanks in advance for any help, and this seems like an awesome community to be involved in!</p>
