Array of textfield

I generated an array of textfield on my table for a quick update of the data on the list. Let's say I have

Code:

---

Id  Name  Address
 1  Jim 
 2  Boy 
 3  Gregg

---

And the addresses are textfields, let's just call it <input type='text' name='address[]' size='12'>. Now I can get the array with this

Code:

---

while (list($k, $v) = @each($_POST['address])) {

---

But how do you guys normally get the field that has value and update it to reflect what address is for whom?

And... am I doing good so far? Or is there a better way of doing this? Thanks.

If the users have auto generated ID's, i.e: in MySql, you should include the user index in the field name. I prefer to use a foreach loop to traverse the array but you way is sufficient.

Don't forget to ensure that the data is an array first.

PHP Code:

---

<input type='text' name='address[<?php echo($row['userId']) ?>]' size='12'>

---

So your field looks like this:

HTML Code:

---

<input type='text' name='address[1]' size='12'>

---

To traverse the array, checking it is an array first:

PHP Code:

---

if (is_array($_POST['address'])) {
    foreach($_POST['address'] as $userId => $address) {
        /* code here */
    }
}
