passing variables to other pages

[julian maisano]

As you'll see, I'm a beginner php guy...

What i'm trying to achieve is:

1) List in AllProducts.php a set of products which are stored in a MySql
table. Each product has a picture. Each picture actually is a link to a
articulodetalle.php, where there will be greater pictures in, plus some
detailed text.
Code in AllProducts.php actually works fine:

$query = "SELECT * FROM articulos";
$result = mysql_query($query);
$i=0;
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
if($i==$public_numero_de_items_por_fila){ //acá cambia de columna
$i=0;
echo "<TR><TH>";
} else {
echo "<TH>";
}
$i+=1;
//here I set up the link to detallearticulo.php *******
echo '<a href="detallearticulo.php?id_articulo=' . $row['id_articulo']
.. '">';
echo '<img width="150" border="0" src="images/' . $row['id_articulo']
.. '.jpg" >';
echo '</a>';
echo "<br>";
echo "id_articulo :{$row['id_articulo']} <br>";
echo "descripcion :{$row['descripcion']} <br>";
echo "precio : {$row['precio']} <br><br>";
}
***** an example of the the link created (in AllProducts.php )is:

detallearticulo.php?id_articulo=xyz325
The problem i'm having is that I've an empty variable value in
detallearticulo.php

$id_articulo (in detallearticulo.php)should have the variable value
associated with the product (xyz325), but it's empty...

What's happening?
Any advice would be apreciated...

in detallearticulo.php do you have line like?

$id_articulo = $_GET['id_articulo'];

Absolutely not :(

I didn't know it was requeired. I'll look to php.net to see what the
hell is $_GET ...

By the way, I looked an example that didn't have $_GET and worked though

You seem to be assuming that $id_articulo will be set for you
automatically. If register_globals is on in php.ini then that
is what will happen, however register_globals is a potential
security risk (when not used correctly) and so its default
value is off since PHP 4.2

The "correct" way to access the variable passed from your first
script is to use $_GET['id_articulo'] instead of $id_articulo

When you pass values in the caller page by:

calledpage,php?thing1=value1&thing2=value2

you get them in the called page, calledpage.php, by:

$variable1 = $_GET['thing1'];
$variable2 = $_GET['thing2'];

It does when register_globals is set to On in php.ini (which is a bad
idea). Another way is to first call:

extract($_GET, EXTR_SKIP);

and then do what you used to do. I wouldn't use that though and stick
with using $_GET['xx'], because you'll see immediately that the variable
in question is a GET variable and it's safer.
