Drupal PHP filter being overwritten in Lexicon Module <p>I've been using the PHP code text format on my Drupal website and I have been encountering a frustrating issue with the Lexicon Module. I bet the answer is dead obvious, but I haven't been able to figure it out.</p> <p>After I write my PHP code in the appropriate text format (php code) in the Lexicon modules "optional introductory text field", I hit save, and everything displays as it should on the page (great!). Problem is when I go back to make changes, "Full HTML" is selected as the text format and the PHP code has been replaced with HTML. When I then choose PHP Code as the text format, I can see some of the code I wrote (not all) but it's commented out with HTML comments. I know that my PHP code has been converted and replace with HTML not only in the input field because if I hit save again, then there is no PHP script saved - just garbled HTML gets displayed on the page.</p> <p>Does anyone know how to use the PHP text format and make sure their PHP code actually sticks around if the content type is revisited? The reason I am putting PHP code in this introductory field in Lexicon is because I need to do a current user language check.</p>
