Current array element in foreach loop

[gehenna801]

I want to traverse an array and set a value equal to the numeric value of the current element.

This is what I've got:

$creds = $_SESSION[$type];

foreach ($creds as $k) {

$name = $k['creditor'];
$balance = $k['balance'];

$id = current($creds);

echo ("  <option value=\"$id\">" . $name . " -- $" . $balance . "</option>\n");

}

}

This is supposed to built part of a select list that sets each option value to the current numerical array element in the loop. However, it's just returning "Array". I've also tried doing away with the

$id = current($creds);

section and just putting value="

$k

". This returns the same thing.

What am I doing wrong here?

in

foreach ($creds as $key => $value) {
   echo $key. ": " . $value . "<br>";
}

$key would equal the array key such as creditor or balance

$value would equal the actual value of that particular key

so I'm not sure what you're trying to do with two different array keys in one loop of the foreach. I just briefly skimmed over this, but in a foreach, you can only access on array key and it's value at once.

Thanks for the reply.

In my loop, $k is a numerical element and $v, if set, would be an associative element

For example:

$creds[0]['creditor'] = Mortgage Company
$creds[0]['balance'] = way too much
$creds[1]['creditor'] = Car Loan
$creds[1]['balance'] = still too much

If my thinking is correct, I'm traversing the $creds array applying each numerical (e.g. $creds[0]) to $k.

I know the loop works, because the rest of the values (e.g. $name = $k['creditor']) are set correctly and the list displays correctly. It's just that the <option value="$id"> or <option value="$k"> is being set to "Array".

Thanks

Can you give me some variables in your array and what you want the output to look like? I'll play around with it later tonight if I can or else tomorrow morning.

Sure:

$type = "debt"; //can be others but one is enough

// here is the code that generates the array
if (!session_is_registered($type)) {

session_register($type);

}

$key = count($_SESSION[$type]);

$_SESSION[$type][$key]['creditor'] = $_POST['creditor'];
$_SESSION[$type][$key]['balance'] = preg_replace("![^0-9\.]+!s", "", $_POST['balance']);
$_SESSION[$type][$key]['payment'] = preg_replace("![^0-9\.]+!s", "", $_POST['payment']);
$_SESSION[$type][$key]['current'] = $_POST['current'];
$_SESSION[$type][$key]['joint'] = $_POST['joint'];

/* this will register the session, if it doesn't already exist and generate the array $_SESSION['debt'][0].  

as the user adds more entrys, [0] will increment accordingly.
*/

/* now that there are some entries in the array $_SESSION['debt'], I want to list them.  

this will create a select field that contains the entries, so far.  

This part partially works.  the select box is generated and the items are listed.
*/

function showCreditor($type)
{
	echo ("<table align=\"center\">\n<tr>\n<td align=\"center\">\n<form action=\"creditor.php?type=$type\" method=\"POST\">\n");
	echo ("<select name=\"creditors\" size=\"5\">\n");

if (!$_SESSION[$type]) {

	echo ("  <option>Add a creditor</option>\n");

} else {

	$creds = $_SESSION[$type];

	foreach ($creds as $k) {

		$name = $k['creditor'];
		$balance = $k['balance'];



		echo ("  <option value=\"$k\">" . $name . " -- $" . $balance . "</option>\n");

	}

}

echo ("</select>\n<br>\n<input name=\"action\" type=\"submit\" value=\"add\">&nbsp;");

if (!$_SESSION[$type]) {

	echo ("\n</form>");

} else {

	echo ("<input name=\"action\" type=\"submit\" value=\"delete\">\n</form>\n");

}

echo ("</td>\n</tr>\n</table>\n");

}

showCreditor();

as you can see in the function above, the value in each <option> tag, should be set to the array element 0, 1, 2, 3, etc. as the loop continues until it runs out of elements. However, when I view source on the output, it shows:

<option value="Array">

This is very simplified. None of the field validation is listed, just the items that apply to my problem... I hope. 😉

I just created my own array and tested. Here's the code:

<?

$creds['0']['creditor'] = "creditor";
$creds['0']['balance'] = "balance";
$creds['0']['payment'] = "payment";
$creds['0']['current'] = "current";
$creds['0']['joint'] = "joint";

    foreach ($creds as $key => $value) {

        $name = $value['creditor'];
        $balance = $value['balance'];

        echo ("  <option value=\"" . $key . "\">" . $name . " -- $" . $balance . "</option>\n");


    }

?>

And here's the output:

<option value="0">creditor -- $balance</option>

If you don't get the same output, then you may want to make sure $creds array looks the same as it does in my code above. If it does, then you'll get the same results.

Hopefully this is what you were looking for.

That's exactly what I'm looking for. I'm sure my array is identical to yours, also. I'll play around some more. Maybe I've overlooked something.

Thank you for taking the time to test this and offer your assistance. 🙂
