[RESOLVED] parsing data from a multi select

[tigomark]

Hello,

I am having a problem parsing the data from a multi-select field

$html = "<select name=\"datatypetarget[]\" size=\"5\" multiple>\n";

The following is my parsing code to create a comma separated field I can put into a database call

	$this->assettarget = ($_REQUEST["assettarget"] ? $_REQUEST["assettarget"] : "NULL::INTEGER");
	//data target handler
    $this->datatypetarget1 = ($_REQUEST["datatypetarget1"] ? $_REQUEST["datatypetarget1"] : "''");
    $this->datatypetarget2 = ($_REQUEST["datatypetarget2"] ? $_REQUEST["datatypetarget2"] : "");
    $this->datatypetarget3 = ($_REQUEST["datatypetarget3"] ? $_REQUEST["datatypetarget3"] : "");
    $this->datatypetarget4 = ($_REQUEST["datatypetarget4"] ? $_REQUEST["datatypetarget4"] : "");
    $this->datatypetarget5 = ($_REQUEST["datatypetarget5"] ? $_REQUEST["datatypetarget5"] : "");
    var_dump($this->datatypetarget1);
    var_dump($this->datatypetarget2);
    var_dump($this->datatypetarget3);
    var_dump($this->datatypetarget4);
    var_dump($this->datatypetarget5);
    if (isset($_REQUEST["datatypetarget"]) && is_array($_REQUEST["datatypetarget"]) && count($_REQUEST["datatypetarget"]) > 0) {

foreach ($_REQUEST["datatypetarget"] as $data_type) {
if ($data_type != "") {
$this->datatypetarget .= "," . $data_type   ;
}else{
$this->datatypetarget = "";
break;
}
}
} else if (!is_array($_REQUEST["datatypetarget"])) {

$this->datatypetarget = $_REQUEST["datatypetarget"];
$this->data->datatypetarget = $this->datatypetarget;
}

Currently from the var_dumps I get

string(2) "''" string(0) "" string(0) "" string(0) "" string(0) ""

so I am missing some values.

When you submit an HTML element (e.g. a multi-select box) with '[]' on the end of it's name, PHP treats that object as an array.

In other words, $_REQUEST['datatypetarget'] is a numerically-indexed array.

I understand that I am trying to find a way to parse those values into a comma separated value to send to a database call.

Or what I should have tried to explain is that I am trying to parse it 2 different ways to see where I was getting a result and that the separating of the info at least gave me the ''. I know it's not correct but trying to handle the information as an array

	if (isset($_REQUEST["datatypetarget"]) && is_array($_REQUEST["datatypetarget"]) && count($_REQUEST["datatypetarget"]) > 0) {

foreach ($_REQUEST["datatypetarget"] as $data_type) {
if ($data_type != "") {
$this->datatypetarget .= "," . $data_type   ;
}else{
$this->datatypetarget = "";
break;
}
}
} else if (!is_array($_REQUEST["datatypetarget"])) {

$this->datatypetarget = ($_REQUEST["datatypetarget"] ? $_REQUEST["datatypetarget"] : "''");

}
var_dump($this->datatypetarget);

Bombs out
