I have set up a registration form and my submit button won't pass through to populate my database with the registration information. The code snipet shows the start of my form and some fields that are included in it.
I had this set up in a table, rather than a form and it seemed to work but when I changed it to a form it stoped working. I've looked at a few other links on here such as this one HTML PHP Contact Form - Submit Button Not Working? Or PHP Issue? But I can't seem to get it working.
<div class = "contact">
<form class="form-horizontal" role="form" method="post" action=" <?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> ">
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Username:</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="username" name="username" value="<?php echo $username ?>">
<span class="error"><?php echo getErrorMessage('username', $error); ?></span>
</div>
</div>
<div class="form-group">
<label for="password" class="col-sm-2 control-label">Password:</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="password" name="password" value="<?php echo $password ?>">
</div>
</div>
<div class="form-group">
<label for="conPass" class="col-sm-2 control-label">Confirm Password:</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="conPassword" name="conPassword" value="<?php echo $conPass ?>">
</div>
<div class="col-sm-10">
<input id="button" name="reg" type="submit" value="Register" class="btn btn-primary">
</div>
</div> <!-- registration button -->
</form>
</div> <!-- registration end --> EDIT: my form stopped submitting information to the database after I tried to validate it, sorry for the incomplete posts very new to Stack Overflow

This is my total PHP script to populate the database. Everything below the //Registration point comment should work as it was working before I added anything above it.

I didn't declare the variables of $password and $conPass at the top of my document and that's what was stopping the submit button not to work.
Thanks for anyone's input on this post.
