PHP question

Hi everybody. I hope someone will help me .
I’m creating my first php dynamic page/pages and I run into a problem. I have declared in MySQL variable Description = longtext, and I have created forms for input and editing as bellow.

Adding Form
…
<textarea wrap=PHYSICAL name="Description" rows=20 cols="100%">Enter your Description...use <br> for line break
</textarea>
……

for edit/display

<textarea wrap=PHYSICAL name="Description" type="text" rows=20 cols="100%" value="<?php echo($Description) ?>" /><?php echo($Description) ?>
</textarea>

form action =”save.php”
save.php

….
$Description = $_REQUEST["Description"];
……

if( condition )
{
$query = "UPDATE `tablename` SET …..
`Description`='$Description' …….

}
else
{
$query = "INSERT INTO `tablename` ( … `Description`, `… )
VALUES ( … '$Description', …)";
}
…….
Problem is that when I enter large text( larger than 700 characters) ‘save’ form doesn’t work or I’m getting error message that data couldn’t been saved.

If I’m entering through MySQL there is no problem with text length.
Any idea?
Thanks

 

Fixed. I just used method='post' insted 'get'. So simple
