发布多个动态文本框值

Question

The textbox is dynamically generated using javascript

var txtLoop = 1;

function add(type) {

if (txtLoop !=23){
    var element = document.createElement("input");


    element.setAttribute("type", "text");
    element.setAttribute("value", "");
    element.setAttribute("name", "txtLine" +txtLoop);
    element.setAttribute("id", "txtLine" +txtLoop);

    txtLoop++;
}

The question is, how can you post this multiple textbox based on how many textbox created?

Answer 1

how can you post this multiple textbox

As long as the textbox has a name attribute, you can access the value:

$_POST['txtLine1']
$_POST['txtLine2']
$_POST['txtLine3']
// ... etc

If you want an array instead, use:

element.setAttribute("name", "txtLine[]");

Then in your PHP code, this will return you an array of values:

$_POST['txtLine']

for ($x=1; $x<=22; $x++) { 
    if (isset($_POST['txtLine'.$x]) && $_POST['txtLine'.$x] != ''){ 
        $txtLine[$x] = $_POST['txtLine'.$x]; 
    } 
}
