copied!<p>I have generated a drop down list in javascript for my form. however when i post the form the the values of the drop down list are null. Even if i select another option from the list, which means it cant be default. Here is my PHP:</p> <pre><code> $BirthDays = ($_POST['Days']); $BirthMonths = ($_POST['Months']); $BirthYears = ($_POST['Years']); </code></pre> <p>And this is the javascript:</p> <pre><code> function runcalender() { var calendar = [ ["January", 31], ["February", 28], ["March", 31], ["April", 30], ["May", 31], ["June", 30], ["July", 31], ["August", 31], ["September", 30], ["October", 31], ["November", 30], ["December", 31] ], cont = document.getElementById('calender'); //set variables for calender var sel_year = document.createElement('select'), sel_month = document.createElement('select'), sel_day = document.createElement('select'); sel_year.setAttribute("id", "Years"); sel_month.setAttribute("id", "Months"); sel_day.setAttribute("id", "Days"); sel_year.setAttribute("name", "Years"); sel_month.setAttribute("name", "Months"); sel_day.setAttribute("name", "Days"); function createOption(txt, val) { var option = document.createElement('option'); option.value = val; option.appendChild(document.createTextNode(txt)); return option; } function clearChildren(ele) { while (ele.hasChildNodes()) { ele.removeChild(ele.lastChild); } } function recalculateDays() { var month_index = sel_month.value, df = document.createDocumentFragment(); for (var i = 0, l = calendar[month_index][1]; i < l; i++) { df.appendChild(createOption(i + 1, i)); } clearChildren(sel_day); sel_day.appendChild(df); } function generateMonths() { var df = document.createDocumentFragment(); calendar.forEach(function(info, i) { df.appendChild(createOption(info[0], i)); }); clearChildren(sel_month); sel_month.appendChild(df); } function generateYears(){ var dateForYear = new Date(); var x = dateForYear.getFullYear(); var y = x - 100; var df = document.createDocumentFragment(); for (i = x; i >= y; i--){ df.appendChild(createOption(i, i)); } clearChildren(sel_year); sel_year.appendChild(df); } sel_month.onchange = recalculateDays; generateMonths(); recalculateDays(); generateYears(); cont.appendChild(sel_day); cont.appendChild(sel_month); cont.appendChild(sel_year); } </code></pre> <p>Do i need to get javascript to select the result manually for PHP to recognize it?</p>
