Using php and html forms to update a mysql database
 
Hi,

Got a bit of a problem with form, i need to be able to update a number in a mysql database using an html form. so basically i need to increment or decrement a number using a text box and a submit button.

heres the code i got:

==============================================

<form name="input" method="get" action="select.php">
Add Stock : <input type="text" name="number1">
<input type="submit" value="+">
</form>
</pre>

<?php
$add = $_REQUEST['number1'];

// update table "goods" contents
$sql =
"UPDATE goods SET stock = stock + $add WHERE id = 1";
"UPDATE stock";
if(!($result = mysql_query($sql,$dblink))) {
print "Fail: query";
exit;
}

?>

===============================================

the code half works but you need to refresh the page and it not updating the database correctly.

also if i made a copy of this code to do the stubtraction it all goes a bit tits up

im guessing there must be a better way for me to do this ?

Someone please help! Merry christmas!

Welcome to Daniweb. This isnt the right forum to post your code. Post it in php forum. Cheers!
Oh, and one more thing. when you post your code, please use [ code] .. [/ code] tags.
