用数据库中的数据填充表单

I have a form that has a field to search records, and from the results, complete the remaining fields of the form with the search results.

The search is performed by the method get from the action of a search button.

In this case the form fields are completed with data collected on the number of locador 106000.

http://localhost/sfi/index.php?number_locator=106000&search-locator=

My problem is that when I access the home page without having made any search, all other fields disappear.

This is because they are within the foreach?

http://localhost/sfi/

If I leave the foreach without closing, the form returns errors in the fields.

<?php foreach ($new_array as $dataForm) ?>

The code:

<?php

if (isset($_GET['search-locator'])){
    // Connect to DB
    $conex = mysql_connect("localhost","root","");

    // Select DB
    $selectDB = mysql_select_db("payment_locations",$conex);

    // Check that the search field is not empty
    if (empty($_GET['number_locator'])) {
        $message = "El campo n° de locador está vacio";
        echo "<script type='text/javascript'>
                  alert('$message');
              </script>";
    }

    // Start search
    else {      
        // Save field content
        $search = $_GET['number_locator'];      
        // Query
        $sql = "SELECT * FROM without_retention WHERE id_locator like '$search'";
        // Execute query
        $result = mysql_query($sql);

        if (mysql_num_rows($result) < 1) {
            echo "No hay resultados";
        }

        else {
            while ($row = mysql_fetch_array($result)){ 
                $new_array[] = $row;
            } 
        }
    }
}
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="get">

    <?php foreach ($new_array as $dataForm): ?> 

            <div class="row col-centered-form-input">

                -->

                 </div>
             </div>
         </div>

I have not put all fields for a logical reason not to fill the topic of code :)

Can be like this? You can check the data and if the data is empty show default form.

<?php
if(!empty($new_array)){
    foreach ($new_array as $dataForm){

        //that your form elements

    }
}else{

    // here the default form elements
}
?>

A solution to apply in the fields.

<input type="text" class="form-control input-borders input-medium-size" value="<?php echo isset($dataForm['period_to']) ? $dataForm['period_to'] : ''; ?>" disabled>
