[SOLVED] a href values

[adrumsolo4u]

i have been searching for a tutorial to explain to me how to do a simple task, but cannot find one.

here is what I'd like to do:

have a link such as this one <a href="?menu=1&sub='variable'">click me</a>

to allow a user to click, and for the link to output a constant (in this case, 1) and also gather a variable. ("variable")

then i will need code to find the values of both "menu" and "sub1" and have those values stored temporarily, until they are change by another link, such as

<a href="?menu='variable'&sub=1">click me too!</a>

 

i am not sure if i explained enough...

any suggestions?

Use this.

<?php
if($_GET['page'] == "WOW") {
if($_GET['sub'] == "") {
echo "FIRST PAGE!?!?!?!?!?";
}
if($_GET['sub'] == "2") {
echo "SECOND OMG LEET";
}
}
?>

could i do this?

 

<?php

private m_page;

private m_sub;

 

if($_GET['page'] == "0") {

return 0;

}

else {

$_GET['page'] ==m_page;

}

if($_GET['sub'] == "0") {

return 0;

}

else {

$_GET['sub'] ==m_sub;

}

?>

 

that would be cool if i could.

oops i mean this:

 

 

<?php
private $m_page;
private $m_sub;

if($_GET['page'] == "0") {
return 0;
}
else {
$this->m_page = $_GET['page'];
}

if($_GET['sub'] == "0") {
return 0;
}
else {
$this->m_sub = $_GET['sub'];
}
?>

[ki]

im not sure what your trying to achieve.

[adrumsolo4u]

i just want a way to GET the values, because i have a different function which will use the new private variables

 

<?php if ($m_sub=="3") echo "<li><a href='#'><span2>+ Page 3.1</span2></a></li><li><a href='#'><span2>+ Page 3.2</span2></a></li>"; ?>

This may help as well...

<?php
  $code=myfunc($_GET['menu'],$_GET['variable']);
  ...
  function myfunc($menu,$var) { {
    if (empty($menu)||empty($var)) {
      $retvar=0;
    } else {
      if ($_GET['menu']=="1") {
        if ($_GET['variable']=="0") {
          echo "Menu 1, variable 0";
          $retvar=1;
        } else if ($_GET['variable']=="1") {
          echo "Menu 1, variable 1";
          $retvar=2;
        } else {
          echo "Menu 1, variable not known";
          $retvar=3;
        }
      } else {
        echo "Menu unknown";
        $retvar=4;
      }
    }
    return $retvar;
  }
?>

 

EDIT: Accidentally used different names for the function.

Basically the cariable $code would contain 0-4 but by adding more ifs you can allow for more functionality although what I've supplied is just an example. If you want help on catering for more data I'd advise on using switch instead.

[adrumsolo4u]

what i'm trying to do is create a nav menu

if lets say "1" were clicked, the variable would become 1, and an if statement containing the two subs would allow it to print the html, while the subs from the other main categories (2,3,4) are not printed, because their if statement is not true.

 

1

+1.1

+1.2

2

3

4

 

 

[adrumsolo4u]

example:

pagevar =(whatever value);

 

echo 1

if pagevar=1{

echo +1.1

echo +1.2

}

echo 2

if pagevar=2{

echo +2.1

echo +2.2

}

Had a feeling you were. Sorry for the delay in replying but I just had major problems getting this to display properly. Off the top of my head, can't guarantee it'll work first time.

<?php
  $menu=$_GET['menu'];
  $sub=$_GET['sub'];
  //Just so you can see what was pulled from the URL
  echo 'You selected '.$menu.((!empty($sub)) ? " and sub menu ".$sub : "").'<br /><br />';
  //Now we build the menu
  echo '<a href="menu.php?menu=1">Option 1</a><br />';
  if ($menu==1) {
    echo '<a href="menu.php?menu=1&sub=1">Menu 1 Sub 1</a><br />';
    echo '<a href="menu.php?menu=1&sub=2">Menu 1 Sub 2</a><br />';
  }
  echo '<a href="menu.php?menu=2">Option 2</a><br />';
  if ($menu==2) {
    echo '<a href="menu.php?menu=2&sub=1">Menu 2 Sub 1</a><br />';
    echo '<a href="menu.php?menu=2&sub=2">Menu 2 Sub 2</a><br />';
  }
  echo '<a href="menu.php?menu=3">Option 3</a><br />';
  if ($menu==3) {
    echo '<a href="menu.php?menu=3&sub=1">Menu 3 Sub 1</a><br />';
    echo '<a href="menu.php?menu=3&sub=2">Menu 3 Sub 2</a><br />';
  }
?>

actually, after taking out the "menu.php5" before the rest of the code in the links, it worked perfectly.

thank you very much for your assistance in ending my aggravating dilemma.

Glad to have been able to help

It's quite easy to add a hidden menu system although this wouldn't be secure and isn't really recommended for anything serious. Add this after the last if...

  if ($menu==2118) {
    echo '<a href="menu.php?menu=2118&sub=1">Menu secret Sub 1</a><br />';
    echo '<a href="menu.php?menu=2118&sub=2">Menu secret Sub 2</a><br />';
  }

That way you'd have to edit the URL in the address bar to change menu to the value of 2118 but only the sub menu would show and you'd never get a menu option for that secret menu showing.
