A variable in the url is not being read using isset

Question

My address is www.mysite.com/test-url?tx=test

if (isset($_GET['tx'])) {
    echo 'Success';

 }

However nothings happening at all, its simply not reading the fact that the variable is there

Your code checked out for me. You might have something in your `.htaccess` that's playing tricks on you or elsewhere. — Funk Forty Niner, Mar 12 '14 at 16:34

Looks like you're using mod_rewrite in your .htaccess file,

so, where you'll have something like this in your .htaccess:

RewriteRule ^([^/\.]+)?$ index.php?page=$1 [L]

You'll need to add QSA like this:

RewriteRule ^([^/\.]+)?$ index.php?page=$1 [L,QSA]
                                             ^^^^

This tells the server to append the query string.. more info at apache.org

what happens if you replace `?` with `&` in your URL? – CᴴᵁᴮᴮʸNᴵᴺᴶᴬ Mar 12 '14 at 16:40
can you post the contents of the `.htaccess` file? – CᴴᵁᴮᴮʸNᴵᴺᴶᴬ Mar 12 '14 at 17:08

hi I found a way around it by using `get_query_var` and adding the get variable in my functions.php – Adrian Mar 12 '14 at 17:25

That's great news Adrian. Did you happen to find it from one of the links I gave you? I noticed it's in there. @Adrian – Funk Forty Niner Mar 12 '14 at 18:37

From what I saw in a comment you wrote, you mentioned that you're on WordPress.

TBH, I'm not a Wordpress guy therefore I wouldn't be able to help and troubleshoot it in a greater scope, but do try the following by adding an extra conditional statement to match the word test in the GET.

The following was successful on my server (not Wordpress). If the URL was test-url?tx= it would fail and if it were test-url?tx=testx it would also fail, therefore only test-url?tx=test will be deemed as successful.

<?php
if (isset($_GET['tx']) && $_GET['tx'] == test) {
    echo 'Success.';

 }

else {
echo "Sorry, the parameter is not set or is invalid.";
}

Edit

Have a look at this and this Q&A where I found the first one from.

I Google'd "if (isset($_GET not working with wordpress php" here you will find many other results, am sure.

Thanks but it must definitely something to do with wordpress because this didnt work either for some reason – Adrian Mar 12 '14 at 17:02
You're welcome Adrian. I wish I could help you further, but as I stated (in my answer) I'm not a Wordpress guy, and thought that by adding the additional conditional statement, that it would have helped. @Adrian – Funk Forty Niner Mar 12 '14 at 17:03
You're welcome @Adrian - If I think of anything (or find) I'll let you know. – Funk Forty Niner Mar 12 '14 at 17:08
