Radio Buttons in PHP post?

[Riseykins]

I've been using this tutorial:

and was wondering if it's possible to add radio buttons?

[DarkWater]

Yes, you can use radio buttons.  Do you need example code?

[Riseykins]

Yes, please. I am VERY new to PHP. I can just about figure out Wordpress, and can edit code, but cannot create it from scratch. xD

Okay.  If you had a form that looked like this:

<form action="test_handle.php" method="POST">
Are you human? <input type="radio" name="human" value="Yes" />Yes <input type="radio" name="human" value="No" /> No <br />
<input type="submit" name="SubmitForm" value="Submit!"
</form>

Notice how they have the same name, but different values.

<?php #test_handle.php
if (isset($_POST['human'])) {
  $human = $_POST['human'];
  switch $human {
         case "Yes":
          echo "Good thing you're human!";
          break;
         case "No":
          echo "Ah omg alien.";
          break;
         default:
           echo "Then what are you...";
           break;
   }
}
else {
echo "Please select an option next time.";
}
?>

 

Now, obviously, you could do more than that, but that should get you on the right track.

OK, well this is my silly glitter crap again!

 

Basically, I want people to be able to choose the style of their glitter text.

 

By selecting a radio button, it will change the folder name that is generated...

[DarkWater]

Post your form code and your PHP code. =)  I'll fix it for you.

[Riseykins]

LOL Thanks.

 

N00b question, but how do I post code? I am not a forum kinda person!

 

I am totally new to this and don't have a clue what I'm doing. I feel awful asking so many questions.

[Dathremar]

I am not sure if i am getting the question right.

 

But if you want to make something to change while you select an option you can list the options available in a list box and make a simple java script for the onChange event.

 

If you need something like that tell me, i am willing to hlp.

 

cheers

Glitter stye:<p />
Not here, yet!<p />

<form>
Text: <input type="text" name="word" size="8" /><p />
<input type="submit" name="btn" value="Submit" />
</form><p />

<div class="h1">Preview</div>
Click "submit" to see a preview.<p />
<?php
if (isset($_GET['btn']))
{
    $word = $_GET['word'];
    $x = strlen($word);
    for ($i=0; $i<$x; $i++)
    {
        $c = $word[$i];
        echo "<img src='http://www.burningviolet.com/glittergen/1/$c.gif' />";
    }
}
?>

<p />
<div class="h1">Code</div>

<textarea><?php
if (isset($_GET['btn']))
{
    $word = $_GET['word'];
    $x = strlen($word);
    for ($i=0; $i<$x; $i++)
    {
        $c = $word[$i];
        echo "<img src='http://www.burningviolet.com/glittergen/1/$c.gif' />";
    }
}
?></textarea>

 

 

The folder named "1" is the folder that I want to change depending on what radio button has been selected.

Just a bump.

Just an FYI, if you create a form and action to to a script with the following code, you'll see all the post variables displayed.

 

<?php
print_r($_POST);
?>

 

Once you can see the post values, view the source; it's easier to look at.

[Riseykins]

Heh. That makes no sense to me. I'm very much a beginner. This is the first thing I've ever attempted to do with PHP...

[Xurion]

With a form, you have to supply the action parameter, for example:

 

<form action="yourfile.php" method="post" name="yourform">

 

When the form is submitted, the values from the text fields, radio buttons etc. are all sent to the yourfile.php. You can then set this script to do things with those values.

 

For a list of the values, use the script i supplied previously, or you can get a value by using the following code:

 

<?php
$yourvariable = $_POST['yourfield'];
?>

[Riseykins]

The thing that I'm finding hard is the fact that when you type a word in one box, an image is generated for each letter.

 

So, each letter URL generated will also need to be modified by selecting different radio buttons.

 

I just can't get it to list in the right order, so to speak...

 

I don't know if this makes any sense!

[Xurion]

No, it doesn't. Is your project online anywhere?
