array first then first+second and so on

[jixor]

Basically I want to make a function that writes the first value in an array, then loops and writes the first+second, then loops and writes the first+second+third, then loops and so on. The array could be anything from 1 item long to whatever.

So far I have well not really been able to get this to work.

Just a side note each item deliminated by / 😉

I would post what I have but I don't want to embarras myself 😉

Basically I am making bread crumb navigation so I take like 'articles/foo/hello'

and explode it into an array

then i want to make breadcrumb navigation like

home > articles > foo > hello

respectively the links would be to
'index.php' > '?doc=articles' > '?doc=articles/foo' > no link for last/current item.

So I would just take the array value and ucfirst() it and that would be the link text.

hmm now that i think about it i think i am taking the wrong approach... ill give something else a go...

Hi. Not tested, but perhaps rework this into a function...

$home_array = array('home');
$bread_array = array('articles','foo','array');
$nav_array = array_merge($home_array,$bread_array);
$link_array = array('index.php','?doc=articles','?doc=articles/foo');
$nav_count = count($nav_array);
for ($i=0; $i<$nav_count; $i++) {
	if ($i == ($nav_count-1)) {
		echo ucfirst($nav_array[$i]);
	}
	else {
		echo "<a href=\"".$link_array[$i]."\">".ucfirst($nav_array[$i])."</a> > ";
	}
}

Cheers.

what so i have to do that for every page, no thanks, i may as well hard code the breadcrumb

[jixor]

Ok I have made this but it doesnt work 🙁

for ($i=0; $i<$queryelements; $i++) {
  $link = $queryelements[$i];
  $linktext = ucfirst($link);
  if ($notfirst == "true") {
    $linkurl = $linkurl . "/" . $link;
  } else {
    $linkurl = $link;
    $notfirst = "true";
  }
  echo "<a href=\"?id=" . $linkurl . "\">" . $linktext . "</a> >";
}

Also I havent thought about a way of making the last item not a link

<?
$nav_string = "link2/link3/link4/link5";
$link_array = array('link1.php','link2.php','link3.php','link4.php');

$the_nav_links = MakeNav($nav_string,$link_array);
echo $the_nav_links;

function MakeNav($nav_string,$link_array) {
	$nav_links = "";
	$home_array = array('home');
	$bread_array = explode("/",$nav_string);
	$nav_array = array_merge($home_array,$bread_array);
	$nav_count = count($nav_array);
	for ($i=0; $i<$nav_count; $i++) {
		if ($i == ($nav_count-1)) {
			$nav_links .= ucfirst($nav_array[$i]);
		}
		else {
			$nav_links .= "<a href=\"" . $link_array[$i] . "\">" . ucfirst($nav_array[$i]) . "</a> > ";
		}
	}
	return $nav_links;
}
?>

Seriously there must be a way that doesnt involve my hard coding all the links into an array beforehand, I mean I have all the information i need already in the array $queryelements. in this example it would contain "articles, foo, and hello"
so i should be able to generate the actual text to put after ?id= from that, somehow.

[jixor]

here is some more code from index.php

if ($_GET["id"] != "") {
  $baseid = $HTTP_GET_VARS["id"];
  $pagetitle = " - " . $baseid;
} else {
$baseid = "";
}

$docid = "docs/" . $baseid;

$docpath = $docid . ".htm";

$docpath = ereg_replace(' ', '', $docpath); 

if (!file_exists($docpath)){
  $docpath = $docid . "/default.htm";
}

if (!file_exists($docpath)){
  $docpath = "docs/error404.htm";
}

$queryelements = explode("/", $baseid);

[jixor]

whoops ok now is good

$count = count($queryelements); 
for ($i=0; $i<$count; $i++) {

Yeah I don't use arrays much 😉

[jixor]

Ok this is what I have, just need to tidy a tiny bit but yeah. If you have any suggestions on how I should improve it then that would be great.

$count = count($queryelements); 
for ($i=0; $i<$count; $i++) {
  $link = $queryelements[$i];
  $linktext = ucfirst($link);
        if ($i == ($count-1)) { 
            $crumbwrite = $linktext; 
        }  else {
  if ($notfirst == "true") {
    $linkurl = $linkurl . "/" . $link;
  } else {
    $linkurl = $link;
    $notfirst = "true";
  }
  $crumbwrite = "<a href=\"?id=" . $linkurl . "\">" . $linktext . "</a> > ";
}
echo $crumbwrite;
}
