This stupid IF issue is driving me nuts 1

[pmonett]

I am trying to create a dynamic menu for a website project.

To do so, I have a configuration file (pagelist.dat) that lists the menu entry and the corresponding file name under the form :

menuname-filename

I have created a function that reads the data file and populates two array variables with the menu option ($options) and the corresponding file name ($files).
This code works.

The next step is to display the menu, highlighting the menu option that corresponds to the page that is currently being displayed.

In order to do that, I catch the current page name from the server at the beginning of the script ($pagename).
Then, when iterating through the $files array, I check to see if, per chance, I'm not on the same one as the page that is currently loaded.
The idea is that, if yes, I use the CSS defined for the selected item, else I use the CSS for the unselected item.

Simple, in theory, but my menu never highlights the page I'm on !

Here is the code :

<?php
	$options[0]="";
	$files[0]="";
	$arraynum=0;
	$selected=0;
	$thisfile=$_SERVER["SCRIPT_NAME"];
	$tab=Explode('/',$thisfile);
	$pagename=$tab[count($tab)-1];
	function getoptions(){
	global $options, $files, $arraynum;
		$input="";
		$ficlist=file("pagelist.dat");
		foreach($ficlist as $input){
			$tab=explode("-",$input);
			$options[$arraynum]=$tab[0];
			$files[$arraynum]=$tab[1];
			$arraynum++;
		}
	}

	getoptions();
	
	echo "<table>";
	echo "<tr><td colspan='2' class='large_section'><br/><br/></td></tr>";
	echo "<tr><td class='menu_section'>";
	echo "<ul id='menu'>";
	$iter=0;
	for($iter=0;$iter<$arraynum;$iter++){
		echo "$pagename=$files[$iter]<br/>";
		if($files[$iter]==$pagename){
			echo "<li class='selected'><a href='".$files[$iter]."' >S".$options[$iter]."</a></li>";
		}else{
			echo "<li class='unselected'><a href='".$files[$iter]."' >".$options[$iter]."</a></li>";
		}
	}
	echo "</ul></td><td><img src='limo.jpg'></td>";
?>

I can add [blue]echo[/blue] commands all over the place, I only confirm that yes, the script knows the proper value of $pagename and the proper value of $files[$iter], but somehow when confronted in the [blue]if($files[$iter]==$pagename)[/blue], it totally forgets their value and moves for the [blue]else[/blue] part !

This is really getting under my skin, as it is a stupid thing that really should not hold me up at all.

Any ideas ? What have I done wrong ?

I've got nothing to hide, and I'd very much like to keep that away from prying eyes.

Perhaps there is an invisible extra character or some other difference between the names in your array, and what you are producing from $_SERVER['SCRIPT_NAME']

Can you post the output from this line:

echo "$pagename=$files[$iter]<br/>";

We may be able to tell you why its different.

Spot on !

And I was being an idiot. Should've known that the file input sequence would keep the /r in the file name.

So now I need to prune /r from the end of my file names.

Which a [blue]Trim[/blue] will do nicely.

Well, thanks for the wake-up !

Glad I could help.
