Using an HTML checkbox to put 1 or 0 into a MySQL table

Question

I am using a simple HTML checkbox in a form to put a 1 for checked and a 0 for unchecked in a field called \"subcheck\" in a MySQL table.

Does the checkbox default t

Answer 1

If the checkbox isn't ticked then nothing is sent to the server. Instead, you can provide a default value with:

$subcheck = (isset($_POST['subcheck'])) ? 1 : 0;

Answer 2

If Checkbox is unchecked then $subcheck is not submited at all.

In PHP you should write:

if !(isset($_POST['subcheck']))
  $subcheck = 0;

mysql_query("INSERT INTO submission VALUES (NULL, '$uid', '$title', '$slug', '$cleanurl', '$displayurl', NULL, '$subcheck')");

Answer 3

To be sure that always 1 or 0 is sent, you can insert an input hidden with the same name of the checkbox in the html:

//The input hidden
<input type="hidden" name="subcheck" value="0" />

//The checkbox
<input type="checkbox" name="subcheck" value="1" /> 

This way, you don't need to check in server side if the textbox is set or not ;)

Answer 4

This can be used as follows

on form page

    <input type="checkbox" name="status" value="1" >

on processing page

    $status = (isset($_REQUEST['status']));
    if ($status == 1 )
      {
        $status = 1;
      }
    else
     {
       $status = 0;
     }
   echo $status;

Answer 5

u should try if statement or ternary condition statement.. if(isset($_POST['subcheck'])) $subcheck = 1; else $subcheck = 0;

or u can try $subcheck = (isset($_POST['subcheck'])) ? 1 : 0;

and in database u should use enum type for subcheck
