Inser checkbox inputs into a postgresql with php - php

Question

I'm trying to introduce the value of a checkbox into my database in postgresql. I created the table account with a colum named: getrequest which is the type boolean.
I'm using the code below, but I'm getting the following error:
Error with query: ERROR: invalid input syntax for type boolean: "" LINE 1: ...account(getrequest) VALUES('', ... ^
Any help would be highly appreciated.
Thanks
<?php
$getrequest = "";
$db = pg_connect('host=localhost dbname=test user=myuser password=mypass');
$getrequest = pg_escape_string($_POST['getrequest']);
$query = "INSERT INTO account(getrequest) VALUES('" . $getrequest . "')";
$result = pg_query($db, $query);
if (!$result) {
$errormessage = pg_last_error();
echo "Error with query: " . $errormessage;
exit();
}
$getrequest = "";
pg_close();
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<input type="checkbox" name="getrequest" value="getrequest" class="regular-checkbox">I get a request<br>
<br>
<input type="submit" name="submit" value="SAVE">
</form>

Verify that the value you are trying to insert is a valid boolean value ( http://www.postgresql.org/docs/9.1/static/datatype-boolean.html ), before inserting, and convert it if needed.
Matbe filter_var($getrequest, FILTER_VALIDATE_BOOLEAN)?'true':'false';
Also, you don't quote boolean or numeric types, Reomove the quotes from your insert statement:
INSERT INTO account(getrequest) VALUES(' . $getrequest . ')'
