<table>
<tr>
<td width="274" align="right" height="25"><strong>Product Name :</strong></td>
<td><input type="text" name="wproname" value="" /></td>

<tr>
<td><input type="checkbox" name="chk<?php echo $result[$i]['w_id'];?>" value="<?php echo $result[$i]['w_id'];?>" id="chk<?php echo $result[$i]['w_id'];?>" onChange="display<?php echo $result[$i]['w_id'];?>();" />

<script>
function display<?php echo $result[$i]['w_id'];?>()
{
if(document.getElementById("chk<?php echo $result[$i]['w_id'];?>").checked)
{
document.getElementById("qty<?php echo $result[$i]['w_id'];?>").style.display="block";
}
if(!document.getElementById("chk<?php echo $result[$i]['w_id'];?>").checked)
{
document.getElementById("qty<?php echo $result[$i]['w_id'];?>").style.display="none";
}
}

<tr>
<td align="right"></td>
<td width="296"><input type="submit" name="Submit" value="Add New" align="middle" class="button login_btn"/></td>

</form>
And I am using this php code for inserting data to the database
$sqls=mysql_query("select * from tbl_warehouse");
while($result=mysql_fetch_array($sqls)) {
$w = $result['w_id'];
echo $_POST['chk'.$w];
foreach($_POST['chk'.$w] as $key=>$val) {
echo $_POST['chk'.$w];
$sql = "INSERT INTO tbl_product(p_id,w_id,p_name,p_qty) values ('','".$wid."','".$wproname."','".$qty."')";
mysql_query($sql);
}
}

Answer 1

You don't need the leading comma in your values list in your insert statement. So change this:
"INSERT INTO tbl_product(p_id,w_id,p_name,p_qty) values ('','".$wid."','".$wproname."','".$qty."')";
To this:
"INSERT INTO tbl_product(p_id,w_id,p_name,p_qty) values ('".$wid."','".$wproname."','".$qty."')";
