[RESOLVED] limiting text box

[karoks]

Hello;

i would like to enter my birthday into textbox.

but i want to input only numeric characters and since it's gonna specify just days i would like to enter a number which is not larger than 31 not smaller than 1.

i couldnt handle this code. can some one help me?

these are my 2 php pages.

Client side:

echo 
'<form action="welcome.php" method="post">
&#304;sim:				<input type="text" name="isim" /><br>       //name
Soyisim:			<input type="text" name="soyisim" /><br> //surname
Do&#287;um Tarihi:		<input type="value" size="1" maxlength="2" name="day" /> / <input type="value" size="1" maxlength="2" name="month" /> / <input type="value" size="2" maxlength="4" name="year" />
'
echo '<input type="submit" />
</form>';

Server side:

$isim=$_POST["isim"];  

$soyisim=$_POST["soyisim"];
$dogum_gun=$_POST["day"];
$dogum_ay=$_POST["month"];
$dogum_yil=$_POST["year"];


echo "welcome:".$isim." ".$soyisim."<br>";

sounds like you want client side validation, ie javascript

Actually i ve figure it out by myself,

if ( isset($dogum_gun) && is_numeric($dogum_gun) && is_int($dogum_gun + 0) && ($dogum_gun >= 1 && $dogum_gun <= 31) && isset($dogum_ay) && is_numeric($dogum_ay) && is_int($dogum_ay + 0) && ($dogum_ay >= 1 && $dogum_ay <= 12) && isset ($dogum_yil) && is_numeric($dogum_yil) && is_int($dogum_yil + 0 ) && ($dogum_yil >= 1900 && $dogum_yil <= 2011))
