Arrays & Foreach?

[bjblackmore]

Hi,
I'm trying to display records from a database, using the database select, and diplaying them as follows:-

<input type="text" name="test[0]['. $key++ .']" size="2">
<input type="checkbox" name="test[1]['. $value++ .']" value="'.$row[0].'">

I then register array $test, which should register $test[0][1] - $test[0][9] and $test[1][1] - $test[1][9]. On the next page, I'd like to display the results like follows: -

"Key: 1; Value: This is value 1"

I'm using the following to display them, but its not working.

foreach ($test as $key => $value) {
echo "Key: $key; Value: $value<br>\n";
}

I get the follwoing error

"Invalid argument supplied for foreach()"

Any Ideas?

Cheers

Brian

The bit I can see is fine; remember though that $test is a two-dimensional array - if $test's value was coming through properly you'd just get

Key: 0; Value: Array
Key: 1; Value: Array

and you'd need to loop through the $value array as well.

But why isn't it coming through intact? could you do a diagnostic and print_r($test) before starting the loop, or just after getting it into PHP in the first place and see if it has the value it should?

And if the answer doesn't become obvious for you then, we'll need to see some more code - particularly the bit in the script where $test is first given its value from the form (basically, its first mention in the script), and any other adventures the variable goes through in case it changes en route.
