im working on a project about a web-based system. I have a form, i want to check if all the fields are filled in but when one of the fields is empty it will show a prompt and will not record the data to the database unless the form have been completed. I am able to show a prompt if the fields is empty but still, it records the data provided even if one or some of the filled is empty.

Here is my html form code:

<script type='text/javascript'>
function notEmpty(elem, helperMsg){
if(elem.value.length == 0){
    alert(helperMsg);
    elem.focus();
    return false;
}
return true;
}

<form action="insert.php" method="post">
FNAME: <input type="text" name="fname" maxlength="50" id="required"/>
MNAME: <input type="text" name="mname" maxlength="50" id="required"/>
LNAME: <input type="text" name="lname" maxlength="50" id="required"/><br/>

Male <input type="radio" name="gender" value="male" /><br/>
Female <input type="radio" name="gender" value="female" /><br/>

College: 
<select name="college">
<option value="default"> --- </option>
<option value="CEC">CEC</option>
<option value="CAD">CAD</option>
<option value="COB">COB</option>
</select>
</br>

<input type="submit" name="formSubmit"    onclick="notEmpty(document.getElementById('required'), 'Please Enter a Value')"
value='SUBMIT'/>
</form>

my php code:

<?php

$con = mysql_connect("localhost","abs","abs");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("testdb", $con);

$sql="INSERT INTO name (fname, mname, lname, gender, college)
VALUES
('$_POST[fname]','$_POST[mname]','$_POST[lname]','$_POST[gender]','$_POST[college]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }

echo "1 record added";

mysql_close($con)
?>

I can’t get it to work. I am new at php. please help me. Thanks a lot !!
