I'm trying to evaluate the value of id
, which should be passed in the POST from jQuery to PHP.
The call is returning {'id':'99'}
, which is ok if id
is not equal to 0. I wonder why ($x == "0")
is not being evaluated to true
in my PHP function.
Any help would be greatly appreciated! Thanks in advance.
jQuery:
$( document ).ready(function() {
$.ajax({
url: '/more.php',
type: 'POST',
data: JSON.stringify({"id" : "0"}),
success: function(data) {
$("body").append(data);
}
});
});
PHP:
if (isset($_POST['id'])) {
$con=mysqli_connect("localhost","user","pass","schema");
getmore($_POST['id']);
function getmore($x) {
if ($x == "0") {
$sqldata = mysqli_query($con,"SELECT * FROM IRCLOG WHERE DATETIME >= date_sub(curdate(),interval 1 day)");
}
else {
$sqldata = mysqli_query($con,"SELECT * FROM IRCLOG WHERE DATETIME >= date_sub(curdate(),interval 1 day)");
}
// your business logic
$rows = array();
while($r = mysqli_fetch_array($sqldata)) {
$rows[] = $r;
}
echo json_encode($rows);
}
}
else {echo "{'id':'99'}";}
I think it might be because PHP is converting the $_POST['id']
to integer. Try the following:
function getmore($x) {
$x = intval( $x );
if ($x == 0) {
Another reason might be that your AJAX is sending the data incorrectly. Try using:
data: {id : "0"}
in the AJAX request.
The data
setting in AJAX call accepts either PlainObject
or String
argument. From the docs:
It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See
processData
option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key based on the value of the traditional setting (described below).
Why don't you use
$(document).ready( function() {
var id_main = 0;
$.ajax ({
type: "POST",
url: "/more.php",
data: { id: id_main },
});
});
send your data like this. data: {"id" : "0"},
