[SOLVED] Create and sort array

[frost]

Hi,

 

I am rubbish at arrays so please bear with me.

 

I have a set of selections that can be assigned numbers for showing:

 

<input type=text name=item1> Item 1

<input type=text name=item1> Item 2

 

The user can assign a sort order to the items, upon submitting the form I would like to pop these into a database as a sorted array.

 

So if they assigned item 1 a value of 5 and item 2 a value of 4 the array would go item2, item1

 

Any help would be really appreciated.

 

Cheers.

I think you just want to use sort()

[frost]

But I need to sort them based on the value supplied by the user right? how would that work?

[gevans]

The html should be;

 

<input type="text" name="item[]"> Item 1

<input type="text" name="item[]"> Item 2

 

The on the page receiving this data use

 

$the_number = count($_POST['item']);//that is assuming you;re using POST

[frost]

But that will just create an array of the values supplied by the user and ignores the item name.

Give this a shot

 

 

<input type="text" name="item[1]"> Item 1
<input type="text" name="item[2]"> Item 2
<input type="text" name="item[3]"> Item 3
<input type="text" name="item[4]"> Item 4

 

 

<?php
if(isset($_POST['item'])) {
	arsort($_POST['item'],SORT_NUMERIC);
	$sortedArray = array_reverse($_POST['item'],true);
	foreach($sortedArray as $item => $order)
		{
			echo 'Item number: '.$item.' Ordered value: '.$order.'<br />';
		}
}
?>

 

This stores the item number in a var called $item and the order by value in the var called $order.
