Okay so I've searched multiple questions that are similar to mine, but aren't quite the same problem. All I'm trying to do is check each textbox in a table to see if it is a numerical value or not. This textbox has a quantity value, so it should only take numbers. Most of my code's in HTML and PHP.
The hidden input is a numerical value that creates the number of rows in the table that comes from the previous page.
I feel like I'm so close but yet so far away....
function validate() { var submitOK = true; var alertstring = ""; var x1 = document.getElementsByClassName('validate-it'); for(var i=0; i" />
<?
$userinput = $_POST['productnumber'];
$count = 0;
do {
echo '<tr>'; ?>
<td>
<select name="product<?=$count?>" rel="cost<?=$count?>">
<option value="0"></option> <?
$sql1 = "select product_id, product_name from product";
$rs=mysqli_query($db,$sql1);
while($row=mysqli_fetch_array($rs)){ ?>
<option selected="selected" value="<?=$row[0] ?>"><?= $row[1] ?></option>
<?}?></select>
<? echo '<td> <input type="text" class="validate-it" name="quantity' .$count. '" value="" /> </td>';
echo '<td> <input type="text" id="cost'.$count.'" name="unitprice' .$count. '" value="" /> </td>';
echo '<td id="totalprice".$count> </td>';
echo '</tr>';
$count = $count + 1;
}
while($count < $userinput);
?>
