how to push data from html grid to mysql?
Question
I am trying to push the data from this simple html grid into sql but I can't do it. in the beginning, I got the error that there was no index for the var impressions. I fixed that. when I use just the advertiser value I can push the data into mysql while with the second value, I can't succeed. can you explain me what I am doing wrong? Thanks in advance
<?php
include_once 'con_ui.php';
if(isset($_POST['btn-save']))
{
$advertiser = $_POST["advertiser"];
$impressions = (isset($POST["impressions"])?
$_POST["impressions"]:'');
$sql_query = "INSERT INTO data(adv, imp) VALUES('$advertiser', '$impressions')";
mysql_query($sql_query);
// sql query for inserting data into database
}
?>

<option value = "Brita ">Brita</option>

There's a few things wrong here:
Firstly the $POST in
$impressions = (isset($POST["impressions"])?$_POST["impressions"]:'');
Is missing an underscore and should be a $_POST
$impressions = (isset($_POST["impressions"])?$_POST["impressions"]:'');
Secondly the browser won't recognize
<td name= "impressions" id="impressions" >1000000</td>
as a form field. If you want to pass on values that the user can't edit you have a few options. You can use a hidden field like:
<td><input type="hidden" name="impressions" id="impressions" value="1000000">1000000</td>
or you can use a text input and disable user input like
<td><input type="text" name="impressions" id="impressions" value="1000000" disabled></td>
