Question

I want to update the database with a checkbox in checked state.

• If it is checked then update the database with 1.
• Else if it is unchecked then update it with 0.

It works fine but it doesn’t work if unchecked.

<?php 
include('lib/db.php');

$facebook_id ="10001088";
$query1 = "SELECT `video`,`quran`,`medical`,`groups`  FROM `man_facebook`.`users` WHERE `facebook_id`='$facebook_id'";
        $result1 = mysql_query($query1);
while($result = mysql_fetch_array($result1))
{
    $video = $result['video'];
    $quran = $result['quran'];
    $medical = $result['medical'];
    $groups = $result['groups'];
    echo $video;
 //   echo $quran;
?>

<form method="post"  action="<? echo $_SERVER['REQUEST_URI']; ?>" >

<input type="checkbox" name="video" id="video" value="<?echo $video;?>" <?php
if($video == '1'){
     echo "checked='checked'";
}
 else {}
echo "/>"
?> 
 <input type="submit" name="submit" value="Submit">
</form>

<?php
}
 if (isset($_POST['submit']))
{
 if (is_numeric($_POST['video']) && $_POST['video'] <2 )
{
 $video1 = isset($_POST['video']) ? '1' : '0';


 echo $video1;
    $query = mysql_query("UPDATE `man_facebook`.`users` 
SET `video` ='$video1'
WHERE `facebook_id`='$facebook_id'");

$video = $video1;
echo '<meta http-equiv="refresh" content="0" />';

    }
    }
//echo $query;
 //header("Location: updatesql.php"); 

?>

Can I also use jquery to update it smoothly?

Answer 1

I find this part a bit weird:

if (is_numeric($_POST['video']) && $_POST['video'] <2 )
{
    $video1 = isset($_POST['video']) ? '1' : '0';

You first check if it is numeric and then check if it is set. If it wasn’t set, that if would become false automatically. In other words, $video is always 1. Assuming $video can be only true/false (or maybe it comes as “checked”/”unchecked”, not really sure), use it like this:

$video1 = ($video ? '1' : '0');

Hopefully I spotted the issue successfully 🙂

UPDATE

<input type="checkbox" name="video" id="video" value="video" <?php
if($video == '1'){
     echo "checked='checked'";
}
echo "/>";

...

if (isset($_POST['submit']))
{
    echo $_POST['video']; // again, please tell what it outputs here!!!
    $video1 = (($_POST['video'] == "video") ? '1' : '0');
