Reinventing the wheel

HI!

Somebody must've done this before, so I'm probably making unnecessary work for myself.

Overview - Allow user to update multiple email addresses using textarea form objects to display each array element from an exploded delimited string.

Technical APproach - 'n' number (dependent upon count of array from an explode() ) of textareas are spawned by PHP on the fly in a form. Each are given an alphanumeric name (email1, email2 etc) and populated with the contents of each array index.

function doTxtareaList($delimitedStr){

$this->StrArray = explode($this->delimiter,$delimitedStr);
$this->StrArrayLen = count($this->StrArray);

$TxtareaList .="<table>";
while(list($index,$content) = each($this->StrArray))
{
$this->newIndex = $index+1;
$TxtareaList .= "<tr><td> <input type=\"text\" name=\"$this->ElementName$this->newIndex\" value=\"$content\"></td></tr> ";
}
$TxtareaList .="<input type=\"hidden\" name=\"StrArrayLen\" value=\"$this->StrArrayLen\"/></table>";

return $TxtareaList;

}

I want to submit the form using PHP_SELF as action. I need to count the number of form objects - not a problem as this comes from the array from above class function- and then implode them into a delimited string for updating the one field in a mysql db.

Problem - THe last bit - putting the email1, email2, etc into an array in preparation for an impode(). How and when do i do it? When action=php_self, the class variables are forgotten right, so how about onSubmit - would that capture modified input from user before page is refreshed.

Hopefully this has been done B4.

The easiest way is to give each of your input texts the same array name

<input type="text" name="email[]" value="$address1">
<input type="text" name="email[]" value="$address2">
...
<input type="text" name="email[]" value="$addressn">

When you submit and subsequently process the sent data

$addresses = $_POST["email"]

Magically, $addresses is an array of the revised addresses.

Wow! That's great. I've been agonising on how to keep my methods encapsulated in the class, else not much point in having a class is there ;-) I did notice (stumble upon) that a http post var is actually an array in that each element is representative of one character of the returned value. :-)

Cheers!

eg

<input type="text" name="email" value="abcd">

echo $email[1]; // std out gives "b"
