how to _post unchecked checkbox value in php

I'm trying to get a value of a checkbox in the database. If the box is checked, the value is 1 If the box is unchecked, the value is 0.

In my index page my table looks like:

<td style="width: 100px" class="auto-style1"><input type="checkbox" name="ele3" id="rallydag" 
value="1"></td>

And in my page, what will put it in my database, i have:

$ele3 = mysqli_real_escape_string($link, $_REQUEST['ele3']);

So i have for every day in the week a different checkbox, people can tell us if they can come that day.

Now every post in my database returns at "1". What do i wrong? I searched a lot, but all doesn't work.

If you must use a checkbox then

<form action="action.php" method="post">
<input type="checkbox" name="ele3" value="1" id="rallydag">
<input type="submit" name="save" value="Save to database">
</form>

then in your action.php

$checkbox_value = !empty($_POST['ele3'])?$_POST['ele3']:0;//if value is empty, set to zero, checkbox not checked
//code to insert to database here

And by the way...avoid using mysqli_connect() .. just adopt PDO::

If checked value 1 else 0 - PHP, If the checkbox is checked I want to insert 1 else 0. if you want to store the values in a database, and you control the front-end of the form just so on for each field, if the check box was not checked than it will not return 1 so then just cycle� You would need to manually convert back the checked/unchecked state of the checkbox to a 0 or 1 for the Oracle DB, as the checkbox can keep only a true/false value by itself. If you bind the grid to an SqlDataSource, on Update and Insert, manually set the UpdateParameter for the field in question.

Try like Below Code:

<?php 
if(isset($_POST['get_checkbox_value'])){
    $ele3[] = $_POST['ele3'];
    $count = count($ele3);
    for($i = 0; $i < $count; $i++){
        if($ele3[$i] == "" && empty($ele3[$i])){
            echo "<script>alert('0')</script>";
        }else{
            echo "<script>alert('1')</script>";
        }
    }
}
?>
<form method="post">
   <table>
        <tr><td style="width: 100px" class="auto-style1"><input type="checkbox" name="ele3[]" id="rallydag"> Day</td></tr>
        <tr><td><input type="submit" name="get_checkbox_value" value="submit"></td></tr>
   </table>
</form>

Comments
  • try something like isset( $_REQUEST['ele3']) ? 1 : 0
  • I have removed the value in the index. Replaced the real-_escape with your isset. But it's still 1. Checked or unchecked
  • Are you talking about updating existing records here? If so, have you checked whether your update statement actually succeeded or not? If it didn’t, you might simply still be looking at "old" data that just did not actually get updated as you expected.
  • Thank you, my value stays 1. checked or unchecked.
  • I have changed the form action and it workd. Doesn't it work with ajax? i have replaced: <form name="profoverzicht" method="post" action="" onSubmit="ajax1.post('rallysend.php','rallysend','content');return false;"> in: <form action="rallysend.php" method="post">
  • it does.. for AJAX just give the form an id and use serialize() to get everything your php remains
  • Haha, sorry, I'm a noob with Ajax/Php. I use the 1st option. I will look how i come back to my page. Thanks allot, it worked!!!
  • Yes! I made a new page, with the code listed above. And it works. Now i have to get it in a database.
