如何在php中发布所选值

Question

In the php script below, I got a checkbox ('solstices') and a pair of radiobuttons which happen to be arrays as well. I want them to be active if the checkbox is checked(it works). So if not checked it operates the last query. However I have a problem with operating these radiobuttons. Only the "Winter Solstice" is working right now no matter if I choose the "Summer Solstice". How can I declare their values sufficiently.

HTML:

    <tr><td colspan="10" align="center"><h2>Solstices</h2></td></tr>
  <tr><td><input name="solstices" type="checkbox" id="solstices" value="1" />Solstices<br /></td></tr>
 <td><input name="check_sol[]" type="radio" id="check_sol[]" value="1" />Summer Solstice</td>
 <td><input name="check_sol[]" type="radio" id="check_sol[]" value="2" />Winter Solstice<br /></td></tr>

PHP:

//DNI CHECKBOX + ALL

if(isset($_POST['solstices'])){
        if(isset($_POST['check_sol'])=='1'){
$tmp="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE=\"2012-06-11\"";
        }
        if(isset($_POST['check_sol'])=='2'){ 
$tmp="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE= \"2011-12-21\"";
        }
}
else {
$tmp ="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE>=\"$fromdate\" AND DATE<=\"$todate\""; 
};

Removed the brackets [] from html code(check_sol[]), propably it is not suitable for radiobuttons. Plus a few noticeable changes in php code.

HTML:

<tr><td><input name="solstices" type="checkbox" id="solstices" value="1" />Solstices</td></tr>
 <td><input name="check_sol" type="radio"  value="8" checked="checked" />Summer Solstice</td>
 <td><input name="check_sol" type="radio"  value="9" />Winter Solstice  <br /></td></tr>

PHP:

if(isset($_POST['solstices'])){
        if($_POST['check_sol']=='8'){
        $tmp="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE=\"2012-06-11\"";
        }
        else { 
        $tmp="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE= \"2011-12-21\"";
        }
}
else {
$tmp ="SELECT DISTINCT ".implode(",", $sql_columns)." FROM $database_Database_Test.$table_name where DATE>=\"$fromdate\" AND DATE<=\"$todate\""; 
};
