Hi. I'm new here.

Let's pretend that this is the code I'm working with (when in fact, I've stripped out all meaning to get to the root of the problem):

Code:

for ($i=0;$i<$somecount;$i++) {
    $item=$i;
    $a->add_field('x_line_item', $item);
}

The objective is to create as many copies of "$a->add_field('x_line_item', $item);" as necessary. But of course, the for loop is simply overwriting each previous version, and only the last loop is saved.

How do I effectively echo each evaluated copy of "$a->add_field('x_line_item', $item);" back into the code, so that each iteration gets processed? Clearly "echo" won't work, right?

If you really want the in-context version, here y'go. It's based on this PHP Authorize.net class.

Code:

require_once('authorizenet.class.php');
$a = new authorizenet_class;
/* more stuff */
$result_cart=db_fetch_cart_by_string("target_id='$tid' AND session_id='".session_id()."' AND status='O'");
if ($result_cart!==false) {
    for ($i=0;$i<sizeof($result_cart);$i++) {
        $item=$result_cart[$i]->product_id."<|>".$result_cart[$i]->product_number."<|>".$result_cart[$i]->product_name."<|>".$result_cart[$i]->quantity."<|>".$result_cart[$i]->price."<|>Y";
        $a->add_field('x_line_item', $item);
    }
}
/* more stuff */
$a->process()

If I can give any more context, do let me know.

Never mind, you useless monkeys. We figured it out. Turns out it was a design flaw in that class I linked to. For the curious: it was storing each field name as an array key, so naturally feeding it multiple "x_line_item" key/value pairs was confusing it, despite the fact that duplicate "x_line_item" fields are acceptable (and expected) by the Authorize.net API. We got around it by appending an iterating number to the end of each x_line_item field name and then modifying the class to remove it during the curl.

Code:

        for ($i=0;$i<sizeof($result_cart);$i++) {
            $item=$result_cart[$i]->product_id."<|>".$result_cart[$i]->product_number."<|>".$result_cart[$i]->product_name."<|>".$result_cart[$i]->quantity."<|>".$result_cart[$i]->price."<|>Y";
            $field="x_line_item-$i";
            $a->add_field($field, $item);
        }

And the modified authorizenet.class.php:

Code:

      $crap=array("-","0","1","2","3","4","5","6","7","8","9");
      foreach( $this->fields as $key => $value ) 
         $this->field_string .= "".str_replace($crap,"",$key)."=" . urlencode( $value ) . "&";

Whee.
