sending a value from drop down box to another page

I have the following drop down box. I want to be able to select a value from this box and using Php sending it to another page.

this is my current code for drop dwon box:

version2:

<form style="margin-top:20px; margin-right:+50px" name="formname" method="post" action="search.php">
<div class="controls controls-row">
<select name="select1" id="select1"> 
<option value="SelectIsland">Select your island</option>
<option value="stMaarten">St. Maarten</option>
<option value="Aruba">Aruba</option>
<option value="Curacou">Curacou</option>
<option value="StBarths">St. Barths</option>
</select>   

<select name="select2"> 
<option value="SelectLoc">Select your location</option>
<option value="Philipsburg">Philipsburg</option>
<option value="SimpsonBay">Simpson Bay</option>
<option value="Maho">Maho</option>
<option value="Cupecoy">Cupecoy</option>
<option value="Middleregion">Middle region</option>
<option value="MadameEstate">Madame Estate</option>
<option value="StPeters">St. Peters</option>
<option value="DawnBeach">Dawn Beach</option>
</select>
<input type="submit" name="button" class="btn btn-primary" value="Find Restaurant" style="margin-top:-10px; margin-right:0px" />
</div>
<?php 
$select1 = $_POST['select1'];
?>
</form>

I am trying to pass $select1 to search.php, using this: $select1 = $_POST['select1'];

however I get this following error, without doing anything: Notice: Undefined index: select1 in C:\wamp\www\iLandgrub.com V 1.2\main page\index.php on line 194, on y index.php.

If I remove $select1 = $_POST['select1']; then it will work but on search.php I dont get the values I wanted.

this my code in search.php:

the same applies for select2, as well. I am already in my index.php withut doing anything I get the error Undefined index.

<?php
if(isset($_POST['select1']) && isset($_POST['select2'])) {
$select1 = $_GET['select1'];
$select2 = $_GET['select2'];
echo $select1;
echo "";
echo $select2;
}
else{
echo "not set";
}
?>

enter image description here this is the error in index.php, when you go to this page.

I solved it. buy using only $_POST, instead of $_get and I also removed 

<?php 
$select1 = $_POST['select1'];
?>

now the error - undefined index - is not showing up anymore, and I get the correct value in the search.php page. thanks guys for helping me.

Here is the error

<a href="search.php" class="btn btn-primary" style="margin-top:-10px; margin-right:0px"type="button" name="button">Find Restaurant</a>

Use a submit button instead of that. 

<input type="submit" class="btn btn-primary" value="Find Restaurant" />

And if you want to use a tag then do like this.

 <a href="Javascript:void(0)" class="btn btn-primary" style="margin-top:-10px; margin-right:0px"type="button" name="button" onclick="document.formname.submit();">Find Restaurant</a>

Give a name to your form tags

<form style="margin-top:20px; margin-right:+50px" name="formname" method="post" action="search.php">

Both the way you can do it. But in your existing code you are not submiting the form rather you are just linked it to the file.

remove the anchor tag from button when you are using action, you have to do something like this 

<input class="btn btn-primary" type="submit" name="button" />

That's because you're using an anchor element. Change

<a href="search.php" class="btn btn-primary" style="margin-top:-10px; margin-right:0px"type="button" name="button">Find Restaurant</a>

to

<input type="submit" class="btn btn-primary" value="Find Restaurant" />

This will post the form data to search.php - if you want the page to submit to itself, change action="search.php" to action="".

Note: you will need to change your CSS to style the button in the same way.
