PHP beginner question

[Ben]

Hello,

I am currently learning PHP, and I have a problem with some variables.
On the first page (choix.php), there is a form that lists product
categories.This is the concerned part:

echo "<form action='dc.php' method='post'>
<select name='p_type2' value='p_type2' > \n";

while ($ligne = mysql_fetch_arr ay($result))
{ extract($ligne) ;
echo "<option value='$p_type2 '>$p_type\n";
}
echo "</select>\n";

echo "<input type='submit'".
"value=\"Choisi ssez un type de produit\"></form>\n";?>

On the other page, dc.php , the program has to list the products in
the category chosen by the user above. I want the product chosen to be
inserted in

$typeproduit = "$HTTP_POST_VAR S[$p_type2]";

where $type_produit is the product chosen. (When i write, for
example,:

$type_produit = "CPU";

the program works. But it doesn't work when I put a variable. Can you
help me ?

Thank you

Try:
$typeproduit = $HTTP_POST_VARS[$p_type2];

The select element does not have a value attribute.

$typeproduit = $_POST['p_type2'];

You mean I should remove the value='p_type2' > /n"; ?
or should I put another value ?

Thank you for your answers guys.

You should remove the value attribute from the select

AFAIK the select construct is like this:

<select name="combo">
<option value="v1">text 1</option>
<option value="v2">text 2</option>
<!-- ... -->
<option value="vn">text n</option>
</select>

And you check it in php with $_POST['combo'] or $_GET['combo']
according to the method used for the form.

The text1, text2, ..., textn are only visible to the browser; you will
not have access to them in the script the form is submitted to --
often they are the same as the v1, v2, ..., vn but that is not
mandatory.

I noticed that Message-ID: <5he4nvca5f74c0 3l7hqg3uss7fd4s krd8j@4ax.com>
from Pedro contained the following:

But if you leave out the value="", text1, text2 etc become the values.
