Question

AutoSubmit Dropdown that passes URL variables using Javascript

Asked by: elfLegolas

I have a function in PHP that generates dynamic dropdowns for me:
<?php
function Dropdown($selectname,$table,$columnval, $columndisp, $selection) {
    echo "<select name='".$selectname."' class='formfield'>";
    $result = mysql_query("SELECT $columnval, $columndisp FROM $table where $columndisp <> '' ORDER by $columndisp ASC");

    while ($myrow = mysql_fetch_array($result)) {
        $optionval = $myrow["$columnval"];
        $optiondisp = $myrow["$columndisp"];
        echo "<option value='$optionval' ";
            if($optionval == $selection)
                  echo "SELECTED";
            echo ">$optiondisp</option>\n";
    }
      echo "<option value='' ";
            if($selection ==  '')
                  echo "SELECTED";
            echo ">Please Select....</option>\n";
    echo "</select>";
}

echo Dropdown("CompanyID","tblCompany", "CompanyID", "CompanyName", "");
?>

Now what I want to do is a location.reload with an OnChange so it passes the CompanyID as a URL parameter. Coming from Cold Fusion, I'm having difficulty figuring out how I can tag the CompanyID in the location.reload command.

Thanks in advance.

use
onChange="gotoloc(document.form_name.select_name.value);" in dropdown

and in the value of dropdown embed the value with the location

 echo "<option value='".$URL."?drop_down_value=".$optionval' ";
          if($optionval == $selection)
               echo "SELECTED";
          echo ">$optiondisp</option>\n";


function gotoloc(location){
      if(location != ""){
            top.location.href=location;
      }
}
the value will be available in drop_down_value on next page
