$_POST['page_id'] nu-i array

[mrslap]

si cum il pot face array?

[Birkoff]

$_POST e o variabila globala de tip array iar

$_POST['page_id'] este o cheie in acel array care ar trebui sa contina ce ii spui tu sa contina

daca in formul tau ai

<input name="page_id" ...

atunci se va trimite un sir nu un array
dar daca pui

<input name="page_id[]" value="a"...
<input name="page_id[]" value="b"...

atunci se va trimite un array cu cheile
0 => a
1 => b

in cazul tau

echo $_POST['page_id'][0] va afisa a si
echo $_POST['page_id'][1] va afisa b

deci depinde cum scrii in form...
