$_Post Question

[KtownJack]

Greetings:

I am a newbie to this forum. I am having a problem accessing the individual elements in a form array. For example, below is a simple example:

The form contains the following

<input type="text" name="material[0]" />
<input type="text" name="material[1]" />
<input type="text" name="material[2]" />
<input type="text" name="material[3]" />

So I have the array material that is numerically indexed. Now when I do a phpinfo(0), the result shows:

POST["material"] Array
(
[0] => 65
[1] => 8
[2] => 8
[3] => 15
)

Now, the problem I am having is I cannot access each individual value in the material array. For example, here is my simplified code;

$i=0;
while ( $i < 4 ) {
$material=$_POST['material[$i]'];
$i++;
}

when I print $material within the loop, it is empty.

I then tried this:

$i=0;
while ( $i < 4 ) {
$material=$_POST['materia'][$i]];
$i++;
}

Again, nothing???

Thanks in advance

it's $POST['materia'][$i], not $POST['materia'][$i]] || $_POST['material[$i]']

it may be easier to do a foreach() loop on the arrays array:

foreach($_POST['materia'] as $key => $value) {
  $material .= $value; // ".=" assuming you're adding to the var and not redefining it
}
