Problems with foreach()

[Schlo_50]

I have some fields representing quantity that are displayed on a page with unique values. The unique values assigned to the fields are the names of the items stored in my database.

 

I am trying to run a foreach() loop so that later I can print out the unique values against the quantities typed in the fields. E.g.

 

Item | Quantity

item1| 3

item2| 5

item3| 3

 

The trouble is, where the string 'Item' should say the item name, it infact says the item number. Hence:

 

Item | Quantity

21    | 3

45    | 5

98    | 3

 

This is my script to generate the fields:

 

<?php
print  "
<input name=\"quantity[{$productid}]\" type=\"text\" size=\"3\" maxlength=\"3\" class=\"main\" onfocus=\"this.style.border='1px dashed #fe9b1b'\" 
      onblur=\"this.style.border='1px solid #a5acb2'\"/> 
<input name=\"orderid[{$productid}]\" value=\"{$productid}\" type=\"hidden\"/> 
<input name=\"quanname[{$productname}]\" type=\"hidden\"/>  		
	";

?>

 

And this is the script to try out the loop:

 

$qua = $_POST['quantity'];
$nam = $_POST['quanname'];
   
   foreach($qua as $a => $nam){
   
   if($nam>0){
   print "$a - $nam<br />";
   
   }

   }

 

Anyone got any ideas?

Thanks!

it has nothing to do with foreach its cause you are using the productid as the array key which i'll assume is an integer and not a string thus you have the issue you say.  use what you want php can't predict it for you.

More to the point, the following makes no sense:

 

$qua = $_POST['quantity'];
$nam = $_POST['quanname'];
   
   foreach($qua as $a => $nam){
   
   if($nam>0){
   print "$a - $nam<br />";
   
   }

   }

 

Anyone got any ideas?

Thanks!

 

You can't plug in an outside value for use in a foreach-loop.  So, either your $a or $nam value isn't what you're hoping it to be.  In other words:

<?php
   $qua = $_POST['quantity'];
   $nam = $_POST['quanname'];

   foreach($qua as $a => $nam){
      /*  $a is the key which, in this case, is the number specifying the current value's position in the array $qua[].
      $nam is ACTUALLY $qua[$a] here, not $nam[$a], as you're overwriting $nam with each iteration of the loop. */
   }
?>

 

Instead of foreach, try a for-loop:

<?php
   for($i = 0; (($i < count($qua)) && ($i < count($nam)); $i++{  //the conditional assumes that $qua and $nam have the same number of values
      if($nam[$i] > 0){
         echo "{$qua[$i]} -- {$nam[$i]}<br />";
      }
   }
?>
