<form action="/en2/maps-<?php echo $id; ?>/?=. ($_GET['textSearchTerms']).&=. ($_GET['locationSearchTerms'])."><!--Relative url to the page that your map is on-->

Distination: 
<select name="textSearchTerms" class="selectpicker" data-live-search="true">
        <option value="alfamart">Alfamart</option>
        <option value="BCA">BCA</option>

<form action="/en2/maps-<?php echo $id; ?> not work... any idea?

I want this link for my form action:

http://indonesia.com/en2/maps-alfamart/?textSearchTerms=alfamart&locationSearchTerms=denpasar

thanks

Use like this

    <?php
        $id="alfamart";
        $textSearchTerms = isset($_GET['textSearchTerms']) ? $_GET['textSearchTerms'] : "";
        $locationSearchTerms = isset($_GET['locationSearchTerms']) ? $_GET['locationSearchTerms'] : "";
        $url = "/en2/maps-".$id."/?textSearchTerms=".$textSearchTerms."&locationSearchTerms=".$locationSearchTerms;
    ?>
    <form action="<?php echo $url; ?>" method="GET">
    Distination:
    <select name="textSearchTerms" class="selectpicker" data-live-search="true">
            <option value="alfamart">Alfamart</option>
            <option value="BCA">BCA</option>
        </select>
    Location:
    <input type="text" name="locationSearchTerms">
    <input type="submit" value="Search">
    </form>

Added form method GET and your php variable in php tag

Replace

<form action="/en2/maps-<?php echo $id; ?>/?=. ($_GET['textSearchTerms']).&=. ($_GET['locationSearchTerms']).">

with

<form action="/en2/maps-<?php echo $id; ?>/?textSearchTerms=<?php echo $_GET['textSearchTerms']; ?>&locationSearchTerms=<?php echo $_GET['locationSearchTerms']; ?>">

Note:- You missed textSearchTerms and locationSearchTerms in your form action parameter before =.
