Pass $_GET variable on form submit - PHP

Question

Apologies if this is a duplicate.

Below is how I pass a variable to my url;

<li><a href="blog-admin-users.php?source=add_users">Create Users</a></li>

From the above, my variable is source=add_users and so the page can get it by checking $_GET[source].

How do I achieve this with a html form.

My form below;

<form method="post" action="nextpage.php" class="search-form">
<div class="grid-33 tablet-grid-33 mobile-grid-100">
<label for="cuisine">LOCATION</label>
<br/>
<div class="select-wrapper">
<select name="location" id="location-select">
<option value="0">Central</option>
<option value="1">Garki</option>
</select>
</div>
</div>
<div class="grid-33 tablet-grid-33 mobile-grid-50">
<label for="day">DAY</label>
<br/>
<div class="select-wrapper">
<select id="activity" name="activity" onchange="changeTime(this);">
<option value="0">Central</option>
<option value="1">Garki</option>
</select>
</div>
</div>
<div class="grid-33 tablet-grid-33 mobile-grid-50">
<label for="time">TIME</label>
<br/>
<div class="select-wrapper">
<option value="0">Central</option>
<option value="1">Garki</option>
</select>
</div>
</div>
<div id="availability-container" class="grid-100">
<input class="find" type="submit" value="FIND FOOD" id="searchfood">
<div class="error" id="notification"></div>
</div>
</form>

When a user clicks on submit, I want it to navigate to page

http://www.test.com/nextpage.php?location=1&day=today&time=12:00

My form has 3 select tags I want to pass the option the user selected to the next page in the url so the next page can use $_GET to use them in a mysql query.

Thanks.

Sidenote: relevance to jquery and ajax tags is? Edit: removed. Show relevance then add them back in respectively. Nothing to support the question/code. — Funk Forty Niner, Sep 23 '15 at 21:03
Did you try leaving off the `method="post"` in your `
` tag? — Rasclatt, Sep 23 '15 at 21:03
Also, `action` would need to point to the right page `nextpage.php`, presumably... — Rasclatt, Sep 23 '15 at 21:04
Also, I hope when you say *"...so the next page can use $_GET to use them in a mysql query"* you mean by way of prepared/bind statement using a `mysqli_` or `PDO` connection...? — Rasclatt, Sep 23 '15 at 21:08
Use `method="get"` instead of `method="post"`, and the form inputs will be sent as URL parameters. — Barmar, Sep 23 '15 at 21:09
I have edited my question. I'm now using GET as the action and I can see all the options in the url in the next page. — moh_abk, Sep 23 '15 at 21:09
@Barmar Thanks, I'm using that now and I can see all in the url of `nextpage.php` — moh_abk, Sep 23 '15 at 21:10
@Rasclatt Yes all my queries are secured against SQL Injection — moh_abk, Sep 23 '15 at 21:11
@Rasclatt I've never heard of Toot Tarts! Sweet Tarts yes, but Toot Tarts?! On second thought, I might like those. — Funk Forty Niner, Sep 23 '15 at 21:14
@Fred-ii- They are imported from Mozambique...I only get the good stuff. — Rasclatt, Sep 23 '15 at 21:14
@Rasclatt I rather Betty Boop Tarts myself, but she's in another world now. And.... what about Columbia? — Funk Forty Niner, Sep 23 '15 at 21:15

in your form action you can send GET values the same way.

<form method="POST" action="poop.php?poop=poop">

why not *toot toot toot!* ? – Funk Forty Niner Sep 23 '15 at 21:09
@Fred-ii- Hmmmmm....valid point...I hope Adelphia has a good explanation for that. – Rasclatt Sep 23 '15 at 21:10
the p and the o are right next to each other. slightly easier than foo and bar, which require me to type with 2 hands :P – I wrestled a bear once. Sep 23 '15 at 21:11
oh, like OOP stuff, but with a zesty twist, ahhhh yes, I get it now. – Funk Forty Niner Sep 23 '15 at 21:13

You have two options.

Option one is to change the form to method="get", and simply send everything as a $_GET request.

The second option is to append your $_GET to the end of the form's action. Since you specified that you want the user to be able to select which page they want to go to, you will need a bit of JavaScript.

In jquery, you can change the form's action with the attr() method.

$('form').attr('action', 'nextpage.php?location=' + location + '&day=' + day + '&time=' + time);

I think jQuery may be heavy handed on this one. A simple form change is better. – Rasclatt Sep 23 '15 at 21:15
that's not true at all.. look at my answer. you can absolutely send both post and get at the same time. – I wrestled a bear once. Sep 23 '15 at 21:15
@Adelphia that's what explained in my second option. – Zsw Sep 23 '15 at 21:16
well, i didn't dispute the second part of your answer. I disputed the part where you said "you can't do post and get at the same time" .. anyway, removed my downvote now that you fixed it// – I wrestled a bear once. Sep 23 '15 at 21:18
@Adelphia I phrased it badly, my mistake. – Zsw Sep 23 '15 at 21:19

I disagree that JQ is heavy handed - assuming it's already included in the page. I like the idea of changing the forms attribute dynamically. You could wrap that up into a little funtion to execute hybrid POST/GET forms :) – I wrestled a bear once. Sep 23 '15 at 21:21
