Answer 1

Do not use

if (!empty($_POST)) {

to check if there is a post done use this:

if( $_SERVER['REQUEST_METHOD'] == 'POST') {

Answer 2

Conditions that you can use with $_POST

if(count($_POST)>0){
    //...
}
if(isset($_POST['field_name'])){
    //...
}
if( $_SERVER['REQUEST_METHOD'] == 'POST') {
    //..
}

Answer 3

Using empty() will fail if value 0 is posted So it is better to use
isset($_POST['FIELD_NAME'])

Answer 4

empty() will work if $_POST does not have any values (Empty array), but in your case when you submit without any values still you get an array like below and it's not empty:

    Array
    (
        [searchlat] => 
        [searchlong] => 
        [search] => Submit Query
    )

empty() will return true only if $_POST returns

Array (

)

But it's not going to happen as every form will have one Sumbit button.

Just use

if($_POST) {
//php code
}

It will solve your problem.
