Nav Menu Questions

tsiedsma

I have a navigation menu that is built in PHP. It detects what page you are on and displays links accordingly.

Here is a snippet of code:

<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/gallery/")
{
$itemis = "Gallery";

} else {

$itemis = "<a href=\"/gallery/\" target=\"_self\" class=\"nav\">Gallery</a>";
}
echo $itemis;
?>

How can I get that to detect other pages within /gallery/ without displaying the link?

If you are in http://www.mysite.com/Gallery/ you should just see Gallery in the navbar instead of an href linking to gallery. Right now if you are in gallery/main.php it shows the href. I want it to just display the word gallery.

I hope this makes sense.

I would expect you would do the following:

<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/gallery/main.php")
{
$itemis = "Gallery";

} else {

$itemis = "<a href=\"/gallery/\" target=\"_self\" class=\"nav\">Gallery</a>";
}
echo $itemis;
?>

If that doesnt work do this to find what the value of $theuri is when you navigate to the page. Then add that into the if statement:

<?php

$theuri = $_SERVER['REQUEST_URI'];

echo('this is the current uri:'.$theuri);

if ($theuri =="/gallery/main.php")
{
$itemis = "Gallery";

} else {

$itemis = "<a href=\"/gallery/\" target=\"_self\" class=\"nav\">Gallery</a>";
}
echo $itemis;
?>

I guess I should have been more specific. I know how to do that, but the problem is that there are a lot of pages in the gallery directory and I want a wild card like gallery/*.php even though that specific example won't work. I don't want to list 20 seperate if statements.

its still not really clear what you want 🙂

You said that you wanted to open the page and for it to say gallery instead of gallery with the href. Looking at the code you have written, the solution i gave you seems adequate to do that.

What exactly do you want to be shown on the page?

Here is the full code. It is menu.php and is included in all of my pages.

<?php

$theuri = $_SERVER['REQUEST_URI'];

if ( ($theuri =="/") or ($theuri =="/index.php") )
{
$itemis = "Home";

} else {

$itemis = "<a href=\"/index.php\" target=\"_self\" class=\"nav\">Home</a>";
}
echo $itemis;
?>
&nbsp;&nbsp;::&nbsp;&nbsp;
<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/gallery/")
{
$itemis = "Gallery";

} else {

$itemis = "<a href=\"/gallery/\" target=\"_self\" class=\"nav\">Gallery</a>";
}
echo $itemis;
?>
&nbsp;&nbsp;::&nbsp;&nbsp;
<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/recipes/")
{
$itemis = "Recipes";

} else {

$itemis = "<a href=\"/recipes/\" target=\"_self\" class=\"nav\">Recipes</a>";
}
echo $itemis;
?>
&nbsp;&nbsp;::&nbsp;&nbsp;
<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/map/")
{
$itemis = "Map";

} else {

$itemis = "<a href=\"/map/\" target=\"_self\" class=\"nav\">Map</a>";
}
echo $itemis;
?>
&nbsp;&nbsp;::&nbsp;&nbsp;
<?php

$theuri = $_SERVER['REQUEST_URI'];

if ($theuri =="/about.php")
{
$itemis = "About Me";

} else {

$itemis = "<a href=\"/about.php\" target=\"_self\" class=\"nav\">About Me</a>";
}
echo $itemis;
?>

When you visit my site, you see this:

When you click on Gallery, you see this:

When you click on About Me, you see this:

You notice that the word Gallery is not white when you are on the gallery page. The reason for this is that there are many pages that in the gallery folder. So instead of specifying

if ( ($theuri =="/gallery") or ($theuri =="/gallery/index.php") or ($theuri =="/gallery/main.php") or ($theuri =="/gallery/blah.php") or ($theuri =="/gallery/blah.php") )

I just want to be able to use a wild card so it detects any page in the gallery folder and displays the menu like this:

Part of the problem is the way the links are: /gallery/main.php?g2_view=core.ShowItem&g2_itemId=28

How can I get my menu script to detect that I am on the gallery page without hard coding the links. It works fine on the rest of my pages.

You could just change one line:-

if ($theuri =="/gallery/")

to:-

if (strpos($theuri, "/gallery/") === 0)

This will check that URI starts with "/gallery/" and will work as a wildcard in the way you want.

Thanks Steven. Works like a charm. I'm learning slowly.
