如何将$ _GET数组的值传递给新的URL？

Question

I have a simple form, when the user entered a code and a mobile number, it should open a new url, here is my code:

<form method='get'>
ID:     <input type='text' name='code'><br>
Mobile: <input type='text' name='mobile'><br>

<?php

echo "<button type='button' onclick='location.href=\"http://workflow.abfarmarkazi.ir/phpsql/sms_info.php?id={$_GET['code']}&mob={$_GET['mobile']}\"'>Submit</button>";

?>

</form>

but the values of $_GET array will not updated, what should I do?

Answer 1

Make form to submit on action url directly. after click submit you will redirect on http://workflow.abfarmarkazi.ir/phpsql/sms_info.php?id=text_id&mob=text_mob

<form method='get' action ='http://workflow.abfarmarkazi.ir/phpsql/sms_info.php'>
ID:     <input type='text' name='id'><br>
Mobile: <input type='text' name='mob'><br>
<input type='submit' value='submit'>
</form>
