JavaScript and forms

Recommended Posts

hey there.

im REALLY new to JS.

ive worked with PHP quite a bit and i seem to know what im doing with it.

i made a form where the user could select a date, it had day, month and year dropdown menu's.

i used a PHP while statement to create the list of days and i have seen you can do this with JS.

the month name was displayed and it had a value called maxday which determined how many days was in the month.

the only problem with this is that it had to refresh the page to make the amount of days appear and i hear that JS doesnt do that.

i will post the code to do the date selection and if you could give me an idea of how to do it in JS that would be awesome

<?php
$month = $_POST['month'];
$year = $_POST['year'];
$dayp = $_POST['day'];
if ($month == "Jan" or $month == "Mar" or $month == "May" or $month == "Jul" or $month == "Aug" or $month == "Oct" or $month == "Dec" or $month == ""){$maxday = 31;}
if ($month == "Feb") {$maxday = 28;}
if ($month == "Feb" && $year == "2008" or $year == "2012") {$maxday = 29;}
if ($month == "Apr" or $month == "Jun" or $month == "Sep" or $month == "Nov") {$maxday = 30;}
?>
<select name="day">
<option> </option>
<?php
$day = 1;
while($day<=$maxday)
{
if($dayp == $day)
{
echo "<option selected>" . $day . "</option>";
}else{
echo "<option>" . $day . "</option>";
}
$day++;
}
?>
</select>
<select name="month" onchange=form2.submit()>
<?php

if($month == "")
{
echo "<option selected> </option>";
}else{
echo "<option> </option>";
}
if($month == "Jan")
{
echo "<option selected>Jan</option>";
}else{
echo "<option>Jan</option>";
}
if($month == "Feb")
{
echo "<option selected>Feb</option>";
}else{
echo "<option>Feb</option>";
}
if($month == "Mar")
{
echo "<option selected>Mar</option>";
}else{
echo "<option>Mar</option>";
}
if($month == "Apr")
{
echo "<option selected>Apr</option>";
}else{
echo "<option>Apr</option>";
}
if($month == "May")
{
echo "<option selected>May</option>";
}else{
echo "<option>May</option>";
}
if($month == "Jun")
{
echo "<option selected>Jun</option>";
}else{
echo "<option>Jun</option>";
}
if($month == "Jul")
{
echo "<option selected>Jul</option>";
}else{
echo "<option>Jul</option>";
}
if($month == "Aug")
{
echo "<option selected>Aug</option>";
}else{
echo "<option>Aug</option>";
}
if($month == "Sep")
{
echo "<option selected>Sep</option>";
}else{
echo "<option>Sep</option>";
}
if($month == "Oct")
{
echo "<option selected>Oct</option>";
}else{
echo "<option>Oct</option>";
}
if($month == "Nov")
{
echo "<option selected>Nov</option>";
}else{
echo "<option>Nov</option>";
}
if($month == "Dec")
{
echo "<option selected>Dec</option>";
}else{
echo "<option>Dec</option>";
}
?>
</select>
<select name="year" onChange=form2.submit()>
<?php
if($year == "")
{
echo "<option selected> </option>";
}else{
echo "<option> </option>";
}
if($year == 2007)
{
echo "<option selected>2007</option>";
}else{
echo "<option>2007</option>";
}
if($year == 2008)
{
echo "<option selected>2008</option>";
}else{
echo "<option>2008</option>";
}
if($year == 2009)
{
echo "<option selected>2009</option>";
}else{
echo "<option>2009</option>";
}
?>
