[SOLVED] a GOTO command?

[Lamez]

I am fairly new to php, but I was wondering is there some sorta goto command that will let me goto a certain part of the script under a certain label?

 

I am working on a password gate, but the script is really dynamic so I was wondering is there a goto command?

 

example:

 

echo "correct";

goto form

 

:form

echo "register";

 

-Thanks

Every C, Java, etc teacher I had have told me that goto is built into most languages, but you should never never never ever ever ever use goto. And that it has been proven that anything you can do with goto, you can do with if else statements. And they've said you can get yourself very confused and in a lotta trouble using thrm. I suggest taking the time to learn loops and if else statements. You'll love them after a little time learning them.

[Lamez]

well I know about IF and ELSE statements and Loops statements, but I am in a jiffy with this script here, and I cannot find anyway around it.

[Wolphie]

The only form of a goto command I've seen in PHP is continue. It can accept optional numeric arguments, however this is only used in loops to skip the current iteration.

 

Example:

<?php
while (list($key, $value) = each($arr)) {
   if (!($key % 2)) { // skip odd members
       continue;
   }
   do_something_odd($value);
}

$i = 0;
while ($i++ < 5) {
   echo "Outer<br />\n";
   while (1) {
       echo "  Middle<br />\n";
       while (1) {
           echo "  Inner<br />\n";
           continue 3;
       }
       echo "This never gets output.<br />\n";
   }
   echo "Neither does this.<br />\n";
}
?>

as you can see where is shows the echoed out correct password, some how I need to get to the registration form, but how?

[dannyb785]

What are you trying to do? I'm positive there's a cleaner and easier way of getting it done.

[GingerRobot]

There are lots of different ways you can do it. For example, you could wrap your registration form in a function and call that, or you could set a variable and check it's value prior to the showing the form.

 

I'm going to direct you to a tutorial on form handling. It really is very good, and i suggest you read it: http://www.rbredlau.com/drupal/node/10

[Lamez]

well dannyb785

 

when the user enters the correct password, I want it to goto the registration form, but I boggled on how to get this done, I have so many if and else statements in the script, I do not know what to do.

 

GingerRobot: I am reading the page you replied with...

[GingerRobot]

I have so many if and else statements in the script, I do not know what to do.

 

And therein lies your problem: lack of planning means you've over-complicated the script. Try to take more time to plan what you're trying to do and plan your logic.

[dannyb785]

I have so many if and else statements in the script, I do not know what to do.

 

 

 

That's because you're trying to output an entirely different page depending on what variables are what value.

 

I don't understand... they put the right password and they are redirected to the registration page? Isn't that before registering??

[Lamez]

I think I might have a solution, I will get back to you guys

[Lamez]

I figured it out, I used headers redirects, and sessions

 

here is my final code:

 

register.php

<?php
ob_start();
$path = "";
$title = "Register";
$login = "no";
$ban = "no";
include ($path."main/include/cons/head.php");
echo '<p class="header">Register</p>';

$r = mysql_query("SELECT * FROM `pgs`");
$row = mysql_fetch_array($r);
if ($row['reg'] == (0)){
  echo '<p class="maintext">Register is disabled at the moment.</p>';
}else
  $r = mysql_query("SELECT * FROM `site_status`");
  $row = mysql_fetch_array($r);
    if($row['pass_on_reg'] == ('1')){
 if (!isset($_SESSION['pass'])){
  //if($_SESSION['pass'] !== (1)){
header('Location: '.$path.'main/include/passgate.php');
        //}
       }else
  

?>
<SCRIPT TYPE="text/javascript">

else
   return true;
keychar = String.fromCharCode(key);

// control keys
