[RESOLVED] foreach loop
Hello. I have this loop :
Code:
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 :
Code:
$strOrder = "";
foreach ($_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 :
Code:
$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??

Re: foreach loop
OK, progress :
Code:
$strOrder = "";
foreach ($_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 :
Code:
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

Re: foreach loop
You're making this way too difficult on yourself. Use PHP's built-in implode() method for making strings out of arrays.
If the post was helpful...Rate it! Remember to use [code] or [php] tags.

Re: foreach loop
Thanx Peej, but I got it working.
I AM SO STUPID!! It was so simple!
Code:
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!
