form redirect

[lord22]

Hi I have a simple login (user and password) form.
This form also includes this multiple menu:

<select name="selectgrade" id="selectgrade">
        <option>A</option>
        <option>B</option>
        <option>C</option>
        <option>D</option>
      </select> 

How can I do that each option will redirect the user to another url?

Thanks

Use the onclick attribute of each <option> to set window.location.href.

but I should redirect the user only when he clicked the button (and he passes the validation..)

<select name="selectgrade" id="selectgrade" onchange="window.location.href=this['options'][this['selectedIndex']]['value']">
	<option></option>
	<option value="http://www.google.ca/">A</option>
	<option value="http://www.yahoo.com/">B</option>
	<option>C</option>
	<option>D</option>
</select>

Actually, after re-reading your post, why don't you just do this with $_POST["selectgrade"] on the validation page? That is, assuming you are using a form.

This is exatcly what I've tried to do, I just don't know how to get the information from the select menu

This is working:

<?php echo $_POST['selectgrade']; ?>
<form method="post" action="<?php $_SERVER['PHP_SELF']?>">
<select name="selectgrade" id="selectgrade">
        <option>A</option>
        <option>B</option>
        <option>C</option>
        <option>D</option>
      </select> 
      <input type="submit" value="Submit">
      </form>

Now, what's the problem on it? What validation are you expecting?

Hope that keeps you going.

Yeah, sorry I didn't look at the "PHP" at the top of the page. I was trying to answer a JavaScript question you didn't have.

The $_POST data will echo the value of the selected index, so you need a value tag in each option.

<?php echo $_POST['selectgrade']; ?> 
<form method="post" action="<?php $_SERVER['PHP_SELF']?>"> 
<select name="selectgrade" id="selectgrade"> 
        <option value="option_a">A</option> 
        <option value="option_b">B</option> 
        <option value="option_c">C</option> 
        <option value="option_d">D</option> 
      </select>  
      <input type="submit" value="Submit"> 
      </form>

Hi

can someone tell what's wrong in here:

$sql="INSERT INTO grades (selectgrade)
VALUES
('$_POST['selectgrade']')"; 

?

It wrote me that there is some syntax error there.
