Why is the data disappearing when refreshing this page?

Navigation
1

While I use this filter to search real estate, everything goes well but at the time I refresh the page, the checkbox causes the search to disappear. It undoes all session or at least it gives an error in the filter that does not allow to continue to recover the other sessions .

How can I improve this script so that the search is not undone by refreshing the page? I repeat, the checkbox is doing this. 

$civil = [];

if(isset($_POST['busca-implacavel'])) {

    if( isset( $_POST['tipo'] ) ) $_SESSION['tipo'] = $_POST['tipo'];
    if( isset( $_POST['civil'] ) ) $_SESSION['civil'] = $_POST['civil'];
    if( isset( $_POST['cidade'] ) ) $_SESSION['cidade'] = $_POST['cidade'];
    if( isset( $_POST['valorminimo'] ) ) $_SESSION['valorminimo'] = $_POST['valorminimo'];
    if( isset( $_POST['valormaximo'] ) ) $_SESSION['valormaximo'] = $_POST['valormaximo'];

    $tipo = isset( $_SESSION['tipo'] ) ? $_SESSION['tipo'] : '';
    $civil = isset( $_SESSION['civil'] ) ? $_SESSION['civil'] : '';
    $cidade = isset( $_SESSION['cidade'] ) ? $_SESSION['cidade'] : '';
    $valorminimo = isset( $_SESSION['valorminimo'] ) ? $_SESSION['valorminimo'] : '';
    $valormaximo = isset( $_SESSION['valormaximo'] ) ? $_SESSION['valormaximo'] : '';

}

Here is the form field code related to checkbox : 

<input type="checkbox" name="civil[]" value="solteiro" <?php echo in_array("solteiro", $civil) ? " checked='checked'" : ""; ?>>Solteiro<br>
<input type="checkbox" name="civil[]" value="casado"  <?php echo in_array("casado", $civil) ? " checked='checked'" : ""; ?>>Casado<br>
<input type="checkbox" name="civil[]" value="viuvo"  <?php echo in_array("viuvo", $civil) ? " checked='checked'" : ""; ?>>Viúvo<br>
<input type="checkbox" name="civil[]" value="divorciado"  <?php echo in_array("divorciado", $civil) ? " checked='checked'" : ""; ?>>Divorciado<br>
<input type="checkbox" name="civil[]" value="uniaoestavel"  <?php echo in_array("uniaoestavel", $civil) ? " checked='checked'" : ""; ?>>União Estável<br>
  

You can repair it right below the%% of the system   continues to return print_r($_SESSION) of índices but does not apply    array $civil .

Thank you:)

Logic error. You are only recovering the SESSION if there is POST in your code.

The correct one is just the part of $ _POST inside if , the rest is: 

if(isset($_POST['busca-implacavel'])) {
    if( isset( $_POST['tipo'] ) ) $_SESSION['tipo'] = $_POST['tipo'];
    if( isset( $_POST['civil'] ) ) $_SESSION['civil'] = $_POST['civil'];
    if( isset( $_POST['cidade'] ) ) $_SESSION['cidade'] = $_POST['cidade'];
    if( isset( $_POST['valorminimo'] ) ) $_SESSION['valorminimo'] = $_POST['valorminimo'];
    if( isset( $_POST['valormaximo'] ) ) $_SESSION['valormaximo'] = $_POST['valormaximo'];
}

// Daqui pra baixo não depende se tem o POST ou não, então é fora do if.

$tipo = isset( $_SESSION['tipo'] ) ? $_SESSION['tipo'] : '';
$civil = isset( $_SESSION['civil'] ) ? $_SESSION['civil'] : array();
$cidade = isset( $_SESSION['cidade'] ) ? $_SESSION['cidade'] : '';
$valorminimo = isset( $_SESSION['valorminimo'] ) ? $_SESSION['valorminimo'] : '';
$valormaximo = isset( $_SESSION['valormaximo'] ) ? $_SESSION['valormaximo'] : '';

Make sure you have session_start() at the top of the page, before that.

A detail: array you need to initialize like this: 

$civil = isset( $_SESSION['civil'] ) ? $_SESSION['civil'] : array();
