Array problem

snapy

Hello all,

Iam doing a footy tipping site, a page I am doing atm is to specify who won game and by what margin.
I can get the page to load into $_POST the winner_id, but the margin is getting me.

I am using a text input which looks like this:

echo ('<td><input type="text" name="margin[]'.$i.'"></td>');

On the processing page it returns this array:

Array ( [w2] => 1 [margin] => Array ( [0] => 12 [1] => 35 [2] => 44 [3] => 52 [4] => 15 ) [w3] => 10 [w4] => 3 [w5] => 2 [w6] => 2 [update] => Submit )

The bit in bold, I have identified as the array for the margin.

What I want to know is how do I get it out of the array and into variables?

My processing page looks like this:

foreach ( $_POST as $key => $value )
{
   // get first char. of $key, if it's 'w', then we've got tips
   if ( substr( $key, 0, 1) == 'w' )
   {
       //to test outputs from array
       print_r($_POST)	;


   $margin = $_POST['margin'];
   //$margin = ;
   $winner_id = $value;
	echo 'winner:'.$winner_id.' margin '.$margin.'<br />';

Any help would be muchly appreciated.

Thank you,

Matt

I don't know if i am understanding this correct but are you saying u want to take all the variables in your ARRAY and create one variable with all the values??

if so
Set your array = to something


$count = count($oldvariable);
//count the variables

for($i=0; $i<$count; $i++)
{
//set all varibles equal to a new one
  $newvariable .= $oldvariable;
//or if u want to echo the array
echo $oldvariable. " " . $i. "<br/>";
}


echo $newvariable; // should echo array i believe

One great thing that is built in (I think in PHP) is there is no need for the '.$i.'.

<td><input type="text" name="margin[]"></td>, will do even though it seems counter-intuitive.

Then, in your PHP code:

$margin = $_POST['margin'];
foreach(array_keys($margin) as $key)
{
     $mar = $margin[$key];

 // some code etc
}

snapy

Thank you both for your input,

topsub, I dont want them all into one variable, I want to put them into a database, and so would like a way to extrat each value and associate it to a certain record.

djneil, this didnt quite fit in with my existing code, I already have a foreach and so your foreach was duplicating the results.

Without my foreach your code works nice, so is there a way to combine the two foreach's into one foreach?

Or is there another way to do this?
