[RESOLVED] Just needing some examples

KeitaroHimura

I'm pretty new to PHP, and I'm wanting to make a script that, upon first visit during the session, presents the user with a dropdown list with the numbers 1-10. Once the user chooses a number, it creates that number amount of text input boxes in a form. Once the user fills out all the forms, it creates a series of buttons, each one with text from one of the boxes.

Basically, the user will choose the number 3, so the script creates 3 input boxes for 3 different names, Once they're all filled out and submitted, it creates 1 button each for each name.

Wow, do you need anything else?
Why do people ask such things before they even sweat?! Do you know some people pay money for an answer to that kind of question?
We'll try to help you with your code, not your apathy.

dagon

ok, well start typing, or hire some one.

Actually, I have tried to write the code. About 3 times, as a matter of fact. I've gotten pretty far into the coding, and then when nothing would work, I would delete the script, and start over from scratch.

I'm not asking any of you to write the script for me, I'm just asking for examples.

dagon

show us what you have, and what specificity is the error.

KeitaroHimura

I have no code now. I have to completely redo it.

"ok, well start typing"

Alright, I will figure it all out for myself then. I didn't know when I signed up to a PHP help forum, asking for help by example would be such an issue.

I mean how hard would it be to help by saying something like
"This may help

<form name="names" method="post" action="<?=$_SERVER['PHP_SELF']?>">
<?
$formnum = $_POST['nums'];
for($num = 1; $num <= $formnum; $num++){
?>
<form name="<?=$num?>" /><br />
<?
}
?>
<input type="submit" name="submit" value="Submit">
</form>

"
or something like that?

KeitaroHimura

See, I'm always able to get that part working, where it shows the input areas, but once it's submitted, I can't get it to create the buttons.

KeitaroHimura

And yes, I know there's a syntax error in that code.

"This may help
PHP Code:

<form name="names" method="post" action="<?php echo $_SERVER['PHP_SELF']?>">
<?php
$formnum = $_POST['nums'];
for($num = 1; $num <= $formnum; $num++){

echo '<input type="text" name="t[]" value="" /><br />';
}
?>
<input type="submit" name="submit" value="Submit">
</form>

KeitaroHimura

The echo is outside of the php code, also, shouldn't there be a $ in front of $t[], also, as I said, I can get that part working, I just did that off the top of my head as an example. I'm needing an example of how to get the buttons created for each of the names inside the input boxes, after that form is submitted.

dagon

sigh, sorry I bothered.

KeitaroHimura

No, thank for at least trying to help. Thank you very much for it, I really appreciate it, I just need help getting it to create the buttons.

KeitaroHimura

Believe me, I know how hard and fun it is to learn on my own, because I've created a few small things of my own, and wracked my brain for days trying to figure things out, and when I did, I was extremely excited. But this script, I've spent the past 2+ months trying to do it, and every time I get pretty far into the code, I always get stuck on the same part, and I've tried and tried and tried, but I can't figure out how to do it, and I've never been able to find examples or tutorials on it.

KeitaroHimura

Alright, I just wrote all this up.

<html>
<body>
<center>
<br /><br />
<?php
if(empty($_SESSION)){
  if(empty($_POST)){
?>
How many people will be playing?<br />
<form name="players" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<br />
<select name="numplayers">
<?php
    for($i = 1; $i <= 10; $i++){
?>
<option><?php echo $i; ?></option>
<?php
    }
?>
<br />
<input name="Submit" type="submit" value="Submit">
<?php
  }else{
    if(!empty($_POST['numplayers'])){
      $_SESSION['start'] = 'true';
      $numplayers = $_POST['numplayers'];
?>
<form name="names" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="playernum" value="<?php echo $numplayers; ?>">
<?php
      for($num = 1; $num <= $numplayers; $num++){
?>
<input name="name<?php echo $num; ?>"><br />
<?php
      }
?>
<input name="submit" value="Submit" type="submit">
<?php
    }
  }
}else{
  if(!empty($_SESSION['start']) && !empty($_POST['name1'])){
  $playernum = $_POST['playernum'];
?>
<form name="names2" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="playernum" value="<?php echo $playernum; ?>">
<?
    for($num = 1; $num <= $playernum; $num++){
    $name = $_POST['name' . $num];
?>
<input type="submit" name="name<?php echo $num; ?>" value="<?php echo $name; ?>"><br />
<?php
    }
?>
</form>
<?php
  }
}

Here's a bunch o' code w\o checking too much the variables (it's 4 am in here, so excuse my.. whatever :queasy🙂.
Go with session variables, indeed, but you should use session_start() at the top of your page (before white-spaces or any output).
Take note of the security hole when you're not sanitizing user input.

You could make a session variable for the entire process using "stepping": just the drop-down - $SESSION["step"] = 1, the X text inputs - $SESSION["step"] = 2 etc.

<form method="POST" action="<?php echo basename($_SERVER["PHP_SELF"]) ?>">
    <select name="num">
    <?php for ($i = 1; $i <= 10; $i++) {
     echo "<option>$i</option>\n";
     } ?>
    </select><br /><br />
    <?php
            if (isset($_POST["num"])) {
                $no = $_POST["num"];
                if (!isset($_POST["t"])) {
                    for ($i = 0; $i < $no; $i++) {
                        echo '<input type="text" name="t[]" value="" /><br />' . PHP_EOL;
                    }
                } else {
                    $t = $_POST["t"];
                    foreach ($t as $button) {
                        echo '<input type="button" value="' . $button . '" /><br />' . PHP_EOL;
                    }
                }
            }
    ?>
    <input type="submit" name="go" value="ok" />
</form>

Thank you so much, nevvermind. That's exactly what I was needing.
