url encoding works but form doesn't
Hello

I am trying to get data from a php form to a mysql database and it just is not working. It works OK when the data is put in URL encoded attached to a URL (so this works...

http://www.aaa.com/ShoppingBag.php?action=add_item&id=123456&QTY=1

)

but not when it is put in via a form

I'm sorry, but this is driving me mental.

Can anyone suggest what the problem might be?

Thanks.


<form action="ShoppingBag.php" method="POST">
<input type="hidden" name="id" value="123456">
<table border="0" width="126">
<tr align="right">
<td width="57"><strong>QTY </strong></td>
</tr>
<tr align="right">
<td><select name="QTY" size="1">
<option
selected>1</option>
<option>2</option>
<option>3 </option>
<option>4</option>
<option>5</option>
<option>6</option>
<option>7</option>
<option>8 </option>
<option>9</option>
</select></td>
</tr>
<tr align="right">
<td colspan="2"><input

RE: url encoding works but form doesn't
You are using the POST form method, but using the $_GET Superglobal to retrieve the values...this will not work. Try changing all the $_GET to $_POST, that should do the trick. As far as not specifying the action in the one form, I have seen this done when posting to the same page that the form is on, but it would probably be better to specify a target page.
