How to get a query string variable in php

Question

I have a php for loop and inside the php for loop there is a button element inside a td tag. I am passing button Id from one page to another using query String.

page 1:

 $id = $data['no'];
<td><button class="btn btn-primary btn-small"><a href="votingPoll.php?'.$str.'">SUBMIT</a></button></td>

To get the value of the button id i have this code in page 2:

$id = $_GET['str'];

but for some reason it's giving me a error of undefined variable 'str' on page 2.

• Mike: In page 1 add var_dump($str); and update your question with the output.

Answer 1

change your code to:

<td><button class="btn btn-primary btn-small"><a href="votingPoll.php?id='.$id .'">SUBMIT</a></button></td>

on yourpage.php or whichever file you would like to recieve the data, access it with $_GET['id']
