I am trying to math between value of 0 but in php code it's work properly but when that value come from database then it does not work.
Here is a demo to test only PHP code:
<?php
$a = 0;
echo $a+1;
?>
The result of this code
1
That ran properly, but when it came from database table then the "+" math does not work properly.
Here is my full code:
<?php
ob_start();
require('config2.php');
// move_up & move_down ** up_down //
$move_up = $_POST['move_up'];
$move_down = $_POST['move_down'];
$up_down1 = $_POST['up_down'];
$up_down11 = $_POST['up_down'];
$forid = $_POST['forid'];
$up = $up_down1-1;
$down = $up_down11+1;
if($move_up) {
if($up_down1) {
$insert=mysql_query("UPDATE widgets_mata SET `up_down` = '$up' WHERE `widgets_mata_id` = $forid");
header("Location: yyy.php");
}
}
if($move_down) {
if($up_down11) {
$insert2=mysql_query("UPDATE widgets_mata SET `up_down` = '$down' WHERE `widgets_mata_id` = $forid");
header("Location: yyy.php");
}
}
?>

Here is my config2.php
<?php
$con = mysql_connect('localhost','root','')
or die(mysql_error());
mysql_select_db ("myweb");
?>
Here is my SQL
CREATE TABLE IF NOT EXISTS `widgets_mata` (
`widgets_mata_id` int(11) NOT NULL,
`widgets_id` int(11) NOT NULL,
`up_down` int(10) DEFAULT '1',
`field` text NOT NULL
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1;
--
-- Dumping data for table `widgets_mata`
--
INSERT INTO `widgets_mata` (`widgets_mata_id`, `widgets_id`, `up_down`, `field`) VALUES
(1, 1, 0, 'R'),
(2, 2, 2, 'R'),
(3, 3, 3, 'R');
--

--

ALTER TABLE `widgets_mata`
ADD PRIMARY KEY (`widgets_mata_id`);

ALTER TABLE `widgets_mata`
MODIFY `widgets_mata_id` int(11) NOT NULL AUTO_INCREMENT,AUTO_INCREMENT=4;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
My problem is with the "0" here:
Then the addition is not working. But when the value is "1"or"2"or"3" then the code works properly.
If you don't understand my question so please run my codes I give full code here
