Hello eveybody! I'm a beginner in PHP. I'm trying to make a fake poll using radio buttons and a script, and my code doesn't work to the point where I'm thinking I've gotten something completely wrong.

I don't need the answer to be stored anywhere, but I need the poll to refresh the page with a thank you message after a vote has been cast. Here is the code of the main page:

PHP Code:

<?php
    
    if ($_POST[vote]=='1') {echo("Thank you for voting.");} 
    else {echo("
    <p><b>QUESTION</b></p>
    <p>&nbsp; </p>
    <form action=\"vote.php\" method=\"post\">
      <p>
        <input type=\"radio\" name=\"vote1\" value=1 > OPTION 1<br />
        <input type=\"radio\" name=\"vote2\" value=1 > OPTION 2<br />
        <input type=\"radio\" name=\"vote3\" value=1 > OPTION 3
      </p>
      <p>&nbsp;</p>
    </form> 
    <input type=\"submit\" value=\"VOTE\" />
    </form>
    ");}
    
    ?>

and the script (vote.php):

PHP Code:

<?php 

$vote=$_POST[vote];

header("main.php?vote=".$vote);

?>

I've been looking at tutorials but I still haven't found what the problem is... The output is crazy wrong, I'm getting fields where there should have been buttons and the ");} ?> trail of the code is showing. Please help...

Two closing form tags and the submit button is on the wrong side of one.

Put ALL the code in one page it does not require two seperate pages.

EDIT: Darn it, you beat me to it Chris :P

The $_POST in your main.php should be using $_GET since you're sending the vote parameter in the url, and you have two closing </form> tags.

Although, it would be much simpler to have it all on the same page. Something in this style

PHP Code:

if (isset($_POST['submit_vote'])) {
   // Thank you etc.
} else {
   // show the form
} 


This simple checks if the form has been submited and if so says "thank you", otherwise it shows the form. The 'submit_vote' from my example should be the name of the submit button. You can ofcourse change it to what you want, as long as you add it to the button (as in <input type="submit" name="submit_vote" ... />)

Radio options in a group should all have the same name (but different values of course).

nothing seems to work... here is the new code (I isolated it in a test script):

PHP Code:

<?php

if (isset($_POST['submit_vote'])) {
           echo("THANK YOU");
}     else {    
           echo("
    <p><b>QUESTION</b></p>
    <br /> 
    <form action=\"test.php\" method=\"POST\">
      <p>
        <input type=\"radio\" name=\"vote\" value=1 > option1<br />
        <input type=\"radio\" name=\"vote\" value=2 > option2<br />
        <input type=\"radio\" name=\"vote\" value=3 > option3
      </p>
      <br />
    <input type=\"submit\" name=\"submit_vote\"/>
    </form>
    ");
}  

?>

and here is a screenshot of the output:

ignore the characters, I actually have text in Greek and I didn't bother putting in the meta tags cause this is just a test script.

could it be an external issue? something with my php?

Well it looks like your code is outputting text inputs (the default) instead of radio buttons,

But as images can't be debugged it's impossible to actually tell why.

It's ok, I solved it. I'm trying to maintain the data when going to other pages now.

should i try session_register? (sorry for doubleposting)

You could use sessions. If so first call session_start() and then use the $_SESSION array to store/read your data.

Or you could add the data as hidden fields in your form and send them again (<input type="hidden" ... />).

Or thirdly, you can have the data as a query string in the URL, as in you_page.php?var1=val1&var2=val2.

Nah, I need the data to be maintained throughout browsing the site. Here is the code so far. (Of course it doesn't work :P)

PHP Code:

    <?php

        if (isset($_SESSION["Submit2"])) {

            echo ("<font size=\"+2\"><b>");
            echo ($_SESSION["select"]);                                   

        [stuff]          
     
        }
    else {
    echo ("

        [stuff]

      <form method=\"POST\" action=\"session.php\">
      
        [stuff]

        <input type=\"submit\" value=\"Go\" name=\"submit2\" />

      </form>
      ");
        }
      ?>

the script (session.php):

PHP Code:

<?PHP

session_start();

echo("*");

if (isset($_POST['Submit2'])) {
    
    echo("*");
    
    $submit2=$_POST['Submit2'];
    
    //$_SESSION['Submit2']=submit2;
    session_register('submit2');
}
/*
if (isset($_POST['select'])) {
$_SESSION['select']= $_POST['select'];
}
*/
//header("Location: main.php");  

?>

You need to call session_start() on every page that you use sessions on, before you can access the $_SESSION array. And you store data in it just as with a normal array:

$_SESSION['submit2'] = $submit2;

It's going ok. Does anybody know how am I gonna get my script to go back to the original page once it's ran though? Cause everything works but once the script that gets the session updated runs(getting POST data) it gets stuck there, It doesn't go back like I thought it would. I could of course use HEADER but I need this to run on every page (think a widget that updates in the same page). Is there any easier way to go other than storing the last url in a variable or something?
