Button to set variable for SQL

[darekw1]

I guess I'm making simple mistake in coding. Could you help?
Trying to get two buttons Swiss and Poland which will set variable to country name and then submit that to SQL database to see records from given country.
However click event does not sets variable but whichever variable is last like Poland in this example:
</head>

<input type="button" name="aa" on (Click)="<? $country = "Swiss"?>;">
<input type="button" name="aa" on (Click)="<? $country = "Poland"?>;">
<form action="searchgo.php" method="post">
<input type="hidden" name="namee" value="<? echo "$country"?>" >
<input type="Submit" value="Updatex">
</form>
</body>
Thanks in advance for any help!

You cannot directly set a PHP variable from within a web page. The onclick event runs on the client side (browser) while your PHP script runs on the server side. I would suggest you use radio button inputs for selecting the country value, then grab that from the form data in the searchgo.php file.

you see my idea is to create interactive map of Europe where you can press country "button" and see all my friends I have in this country. Radio buttons and forms are ok but not very eye pleasing. Any ideas I can do this ?

<form action="searchgo.php" method="post" name="country_form">
<input type="button" onclick="country_form.namee.value='Swiss'">Swiss</button>
<input type="button" onclick="country_form.namee.value='Poland'">Poland</button>
<input type="hidden" name="namee" value="<? echo "$country"; ?>" >
<input type="Submit" value="Updatex">
</form>
