What am I missing?

derrickc · October 5, 2011

I have had this piece of code working a few hours ago, I tried tweaking it a bit and thought that I changed it back, but it still isnt working properly. Very simple fix, I feel it is right in front of me but cant seem to see it. Very simple, I'm adding dynamic text boxes and processing the the textboxes into an array. To preface what I have done to warrent this outcome below is added 3 dynamic boxes to the already existing text box. Box1.text = d, 2=6, 3=d, 4=d. The outcome here is just my trouble to see where the problem is and I cant seem to find it. please helps. Thanks in advance.

This is the output:

0d

<script>

function addRowToTable()
{
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow;
var row = tbl.insertRow(lastRow);

// left cell
var cellLeft = row.insertCell(0);
var textNode = document.createTextNode(iteration);
cellLeft.appendChild(textNode);

// right cell
var cellRight = row.insertCell(1);
var el = document.createElement('input');
el.type = 'text';
el.name = 'txtRow[' + iteration + ']';
el.id = 'txtRow[' + iteration + ']';
el.size = 40;
cellRight.appendChild(el);
}

function removeRowFromTable()
{
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
if (lastRow > 2) tbl.deleteRow(lastRow - 1);
}


</script>

<input type="button" value="Add" onclick="addRowToTable();" />

<input type="button" value="Remove" onclick="removeRowFromTable();" />

<tr>

<th colspan="3">Sample table</th>

</tr>

<tr>

<td>1</td>

<td><input type="text" name="txtRow[]" id="txtRow[]" size="40" /></td>

</tr>

</table>

</form>

last.php looks like this:

	for($i = 0; $i < count($_POST['txtRow']); $i++){
             $textboxarr = $_POST['txtRow'][$i];
echo $i . $textboxarr .  "<br/>";;
    }
