However the TinyMCE editor returns a HTML body tag for each field in the form. T

its not a very ellegant solution but it works. i simply remove the tags from the document using the strip_tag(), then test if the variable is empty. If its not empty i submit the post variable.

if (isset($_POST['description']))
                {
                    $preValidated = dsf_db_prepare_input($_POST['description']);
                    $testValue  = trim(strip_tags($preValidated));

                    if(!strlen($testValue) >= 1)
                    {
                        $description ='';
                     }
                     else
                     {
                        $description ="$preValidated";
                     }     
                }
