[RESOLVED] foreach loop

[HanneSThEGreaT]

Hello. I have this loop :

	foreach ($_POST['ordered'] as $key=>$id) {
		echo '<p/>
		ProdName: ' , $prod[$id]['name'] , '<br/>
		ProdPrice: ' , $prod[$id]['price'] , '<br/>
		ProdQty: ' , $prod[$id]['qty'] , '
		<hr/>';
  }

Now I am trying to create a string variable to hold all this results, so, the variable must get appended the whole time, and then stored inside a Hidden field. Simple. NO!

I have tried this :

	$strOrder = "";
	
	foreach ($_POST['ordered'] as $key=>$id) {
		echo '<p/>
		ProdName: ' , $prod[$id]['name'] , '<br/>
		ProdPrice: ' , $prod[$id]['price'] , '<br/>
		ProdQty: ' , $prod[$id]['qty'] , '
		<hr/>';
		
		$strOrder .= $key . " " . $id;

Nothing gets stored inside strOrder.

I created the hidden fields like this :

		$TOT2 = $TOT + 55;
		
		echo	'<input type="hidden" Name="TOT" value ="'. $TOT .'">';
		echo	'<input type="hidden" name="TOT2" value =". $TOT2 .'">';
		
		echo 	'<input type="hidden" name="Order" value=". $strOrder . '">';

But NOTHING gets stored in any of them either.....

What am I doing wrong now??

OK, progress :

	$strOrder = "";
	
	foreach ($_POST['ordered'] as $key=>$id) {
		echo '<p/>
		ProdName: ' , $prod[$id]['name'] , '<br/>
		ProdPrice: ' , $prod[$id]['price'] , '<br/>
		ProdQty: ' , $prod[$id]['qty'] , '
		<hr/>';
		
		$strOrder .= $key . "," . $id.";";
		
	
		$TOT += $prod[$id]['price'] * $prod[$id]['qty'];
		
	}
	
		$TOT2 = $TOT + 55;
		
		echo	'<input type="hidden" Name="TOTAL" value ="'. $TOT .'">';
		echo	'<input type="hidden" name="TOTAL2" value ="'. $TOT2 .'">';
		
		echo 	'<input type="hidden" name="Order" value="'. $strOrder . '">';
}
	echo "strOrder String == $strOrder";

Gives me :

strOrder String == 0,2;1,11;2,20;

It seems as if the array indexes are stored into strOrder in stead of those indexes' values. I need the values inside the Order hidden field

You're making this way too difficult on yourself. Use PHP's built-in implode() method for making strings out of arrays.

Thanx Peej, but I got it working.

I AM SO STUPID!! It was so simple!

	foreach ($_POST['ordered'] as $key=>$id) {
		echo '<p/>
		ProdName: ' , $prod[$id]['name'] , '<br/>
		ProdPrice: ' , $prod[$id]['price'] , '<br/>
		ProdQty: ' , $prod[$id]['qty'] , '
		<hr/>';
		
		$strOrder2 .= "<p/>ProdName: " .  $prod[$id]['name'] . "<br/>ProdPrice: " . $prod[$id]['price'] . "ProdQty: " . $prod[$id]['qty'];
		
		
		$TOT += $prod[$id]['price'] * $prod[$id]['qty'];
		
	}


		$TOT2 = $TOT + 55;
		
		echo	'<input type="hidden" Name="TOTALH" value ="'. $TOT .'">';
		echo	'<input type="hidden" name="TOTAL2H" value ="'. $TOT2 .'">';		
		echo 	'<input type="hidden" name="Order" value="'. $strOrder2 . '">';

Thanx anyways!
