Simple loop counter

[allinurl]

Hello, What I'm trying to do is basically the same thing is doing right now, with the same formula, with the exception of, when I click 1 the <a href> shouldnt be "index.php?num=-10&var=1" it should be just index.php

 

$num = ((int) $_GET['num']);
for ($i = 1; $i < 12; $i++) {
    $val = ($i - 2 )* 10;
    if ($val < -10) {
        print '<strong><a href="index.php">'.$i.'</a></strong> ';
    } else if ($val != $num) {
        print '<strong><a href="index.php?num='.$val.'&var=1">'.$i.'</a></strong> ';
    } else {
    	print $i.'  ';
    }
}

 

Thanks in advance

I'm confused about what your trying to archieve, coudl re-explain?

thanks for your reply, well basically what I'm trying to do is a counter that for instance when I click in number 2 the $num value should start at 0, if I click on 3 the $num value should be 10 and so on, but when I click on 1 it should be just the url with out any param. In addition it doesn't make the current number a link.

well, you could add a condition to check if $i == 1 and if so, build link without the added stuff, or you could just do a plain echo of it before the loop and start your loop at 2 instead of 1.

if I add a condition to check if $i == 1 then when I click 1 it keeps been a link

 

$num = ((int) $_GET['num']);
for ($i = 1; $i < 12; $i++) {
    $val = ($i - 2 )* 10;
    if ($i == 1) {
        print '<strong><a href="index.php">'.$i.'</a></strong> ';
    } else if ($val != $num) {
        print '<strong><a href="index.php?num='.$val.'&var=1">'.$i.'</a></strong> ';
    } else {
    	print $i.'  ';
    }
}

if ($i <= 1) {
#code
}

well I think this is what you are trying to do...

 

$num = ((int) $_GET['num']);
for ($i = 1; $i < 12; $i++) {
    $val = ($i - 2 )* 10;
    if ($val != $num) {
       if ($i == 1) {
           print '<strong><a href="index.php">'.$i.'</a></strong> ';
       } else {
          print '<strong><a href="index.php?num='.$val.'&var=1">'.$i.'</a></strong> ';
       }    
   } else {
    	print $i.'  ';
    }
}

thanks both, but when I click on 1 still makes me look like if I'm in number 2, and 1 is still a link. The idea is basically the same functionality as now, but when I click on each number I dont wanna make that current number a link

[.josh]

well i have no idea what the point of $val is supposed to be but if you want the "current" one not to be a link then you need a condition to see if ($i == $num)

[allinurl]

where specifically I should have the condition?

[.josh]

if you have a bunch of numbers you want to loop through, and one of those numbers you want to do something special with, where do you think the condition should be?

[allinurl]

beginning, but still don't get it.

[allinurl]

got it thanks
