PHP form textarea array submission

Hi,

I would like to request an assistant.

I have the following textarea form , which is generated as array by php :

<textarea name='remark[]' id=$invoiceid cols='10' rows='1'>
</textarea>
<input type='submit' value='Go' name='SubmitRemark'>


I use the following PHP scripts to record :


if(isset($_POST['SubmitRemark'])){
$textareaarray=$_POST['remark'];
$invoiceid=$_POST['invoiceid'];
foreach($textareaarray as $textarea) {
$sql=mysql_query("UPDATE domainorder SET remark='$textarea', datepaid=NOW() WHERE invoiceid='$invoiceid' " , $conn);
if($sql){echo "<p><font face='Arial'><b>Domain DB Updated</b></font></p>";}}}


It seems the above php script not able to capture the post data and not record in the mysql.

Can anybody help to check and provide the complete new php scripts to handle textarea array ?

Appreciates anybody assistant.


Thank you.
