You need to write a javascript/jquery code in order to send an AJAX request upon the selection of any option within the first drop-down in order to fetch the second set of your data from database. then after the AJAX response with its data went back to your AJAX function, use another javascript/jquery function to access to the second select tag (using id/class) and fill it up with the acquired data! Refer to this youtube video tutorial for understand the concept behind this and implement it in your own code -> Tutorial [this video]

I'm having problems trying to access a function inside a JavaScript script, so I can create a dynamic set of possible dates based on what month is selected. It doesn't even seem to access the JavaScript function 'populate()' at all. The alert doesn't respond. I should probably mention this entire code is called from 'include_once();' in another file. I tried to follow the example from: [this video] <script type="text/javascript"> function populate(month,day){ alert('Javascript Reached'); var month = document.getElementById('month'); var day = document.getElementById('day'); day.innerHTML=""; if (month.value == "Apr" || month.value == "Sep" || month.value == "Jun" || month.value == "Nov" || ){ var
