Introduction

Code:
 <html>
<body>

<form action="welcome.php" method="post">
Age: <input type="text" name="age" />
<input type="submit" />
</form>



That's the HTML of it, I guess...I'm new to this so please go easy on me...That goes before the actual code.

Grab the Code

<? if($age >= "18");  {
 echo "Hello, you are $age "; }
else{
 echo "Sorry, you are not the correct age."; }
?>
</body>
</html>

You should just put all the code together into the snippet. There's no reason to separate it like this. Also, always use <?php instead of <? to avoid compatibility problems with certain servers.

Also not all servers have.... uhmmm can't think of it of the top of my head, but they won't allow $age they require you to do $age = $_POST['age'];.


Not bad for a first script :) Hope to see more, and if your stuck on a problem, yell out on the forums and we'll all help out =)

Sure its not the best script out there, but its your first PHP script. I know my first php script was

Code:
<?php echo "Hello World"; ?>
you wouldn't believe how much problems i had, firstly i had <?php hello world ?> i spent hours trying to get it to work, i ended up asking RussellReal and he told me i was missing the " and the ; but he wasn't going to tell me where.

We all start off at the same place, it doesn't matter what the quality of the script is, its worth the knowledge of what you gain from creating this script.

Danger, why don't you edit the snippet to reflect our suggestions?

Nice to see another PHP scripter out there :L lacks a few on this site hehe.

I must be bored or something.. but this would incorporate all your HTML & PHP together;

Code:
<?php
echo '<html>
      <body>';

if (!$_POST) {
  echo '<form action="' .$_SERVER["PHP_SELF"]. '" method="post">
        Age: <input type="text" name="age" />
        <input type="submit" />
        </form>';
}
else {
  $age = $_POST["age"];
  if ($age < 18) {
    echo 'You are too young';
  }
  else {
    echo 'Welcome';
  }
}
?>

Set a variable with the post, it should parse all symbols.. i think, never really had the need to try it out before..

Nah, PHP won't parse symbols like that, it will just print it back to the page.

Try this instead...

Code:
<?php
$form = "<form action=\"test.php\" method=\"post\"><input type=\"text\" value=\"\" name=\"one\"/><br/><input type=\"text\" value=\"\" name=\"two\"/><br/><input type=\"text\" value=\"\" name=\"three\"/><br/><input type=\"submit\" value=\"submit\" name=\"submit\"/></form>";

if($_POST["submit"])
{
  if($_POST["two"] == "+") {$value = $_POST["one"] + $_POST["three"]; echo $_POST["one"] ." + " . $_POST["three"] . " = " . $value;}
elseif($_POST["two"] == "-") {$value = $_POST["one"] - $_POST["three"]; echo $_POST["one"] . " - " . $_POST["three"] . " = " . $value;}
elseif($_POST["two"] == "*") {$value = $_POST["one"] * $_POST["three"]; echo $_POST["one"] . " * " . $_POST["three"] . " = " . $value;}
elseif($_POST["two"] == "/") {$value = $_POST["one"] / $_POST["three"]; echo $_POST["one"] . " / " . $_POST["three"] . " = " . $value;}
else echo "You have entered an unknown operator!";



}

else echo stripslashes($form);


?>

Hi,

I need a code that lets my customers upload a image file from their computer and then that file does 2 things

1. gets uploaded to upload folder on my server
2. a copy of that file gets e-mailed to me

this is what I have so far, any improvements/additions on this code would really be appreciated...

1.//GET IMAGE INFO
2.
3. $dir = 'images/';
4. $file_name = $_FILES['file']['name'];
5. $file_tmp = $_FILES['file']['tmp_name'];
6.
7. //CHECK FOR UPLOADED FILE
8. if(is_uploaded_file($file_tmp)){
9. //MOVE TO DIR
10. move_uploaded_file($file_tmp, $dir.$file_name);
11. }

Thanks & regards,
Lokananth
