PHP if on a certain page...

ts10

I have included my links file in my webpage. Here's the think though, I have JS rollovers in the links that I only want used if I am at home.php - not any of my other pages.

So, I plan to use an IF statement to determine whether or not to use the rollovers. But, what is the condition? How can I check to see if I am at home.php and if so allow the rollovers?

Thanks in advance!

ok, for future reference you'll probably want to check out predefined variables

http://uk2.php.net/manual/en/reserved.variables.php#reserved.variables.server

as for your script you should be looking at something like this

<?

$script = $_SERVER['SCRIPT_NAME']; // GETS FILE NAME

if ($script == '/home.php') {
    // ECHO CODE FOR ROLLOVERS
}
else {
   // ECHO CODE WITHOUT ROLLOVERS
}
?>

that should be the basis of what you want, if you have anymore problems, just ask

ts10

Hmm, doesnt appear to be working. Here's my code:

Top of my file:

<?
$script = $_SERVER['SCRIPT_NAME']; // GETS FILE NAME
?>

In the link:

<a href="latestinfo.php" <?if ($script == '/home.php') {echo "onMouseover=\"changetext(content[0])\"";}?>> • Latest Information</a><br>

I'm on home.php and now when I rollever it just doesn't show up as if I were on a page other than home.php.

Thanks for your help!

hhmm....

it seems that although 'SCRIPT_NAME' is a preset variable for $_SERVER global php doesnt wanna accept it

however 'SCRIPT_FILENAME' works just fine

so change your declaration at the top to

<?
$script = $_SERVER['SCRIPT_FILENAME']; // GETS FILE NAME
?>

and change your if statement to

$script == 'home.php') // WITHOUT THE FORWARD SLASH

HTH

ts10

😕

Same thing - no error, just doesn't show the rollover.

tuf-web_co_uk

where is

changetext(content[0])

coming from?

and what type of rollovers do you want exactly?

ts10

The links file is an include file (links.inc) included in the home.php page.

changetext(content[0]) is in the home.php page. It works great until I add the php script check. Should I send you more info to see? Or any other ideas?

Thanks!

tuf-web_co_uk

is changetext(content[0]) a function or something?

more code would be greatful, thx

ts10

home.php :

<script>
<!--

var content=new Array()

function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers){
appear()
setTimeout("window.onresize=regenerate",450)
}
}

function changetext(whichcontent){

if (document.all||document.getElementById){
cross_el=document.getElementById? document.getElementById("descriptions"):document.all.descriptions
cross_el.innerHTML='<font face="Verdana"><small>'+whichcontent+'<font></small>'
}
else if (document.layers){
document.d1.document.d2.document.write('<font face="Verdana"><small>'+whichcontent+'</small></font>')
document.d1.document.d2.document.close()
}

}

function appear(){
document.d1.visibility='show'
}

window.onload=regenerate2


//-->
</script>

Also in home.php where the code should display:

<div id="tooltips">
		<ilayer id="d1"visibility="hide">
		<layer id="d2">
		<div id="descriptions" align="left">



	</div>
	</layer>
	</ilayer>
</div>

Then, my links.inc file:

<?
$script = $_SERVER['SCRIPT_FILENAME']; // GETS FILE NAME
?>
   <a href="latestinfo.php" <?if ($script == '/home.php') {echo "onMouseover=\"changetext(content[0])\"";}?>> • Latest Information</a><br>

content[9]='<b>Repository of the TENA Object Model Team's Candidate Object Models suitable for reuse in your range-specific object model designs</b>'

has a ' in the middle of the script which may cause problems later on try escaping it so it doesnt affect your code

and for javascript functions you should probably use

onMouseOver="javascript:changetext(content[0]);"

in your links.inc file echo out $script to see what you get

ts10

In my echo I get the full path "C:/Program Files/Apache Group/Apache2/htdocs/fi_template/home.php"

tuf-web_co_uk

ok, fix the problem with the javascript

then change $SERVER['SCRIPT_FILENAME'] back to $SERVER['SCRIPT_NAME']

and that should do the trick

ts10

That echo gives me "/fi_template/home.php". Is there a way I can get that to just the /home.php?

Thanks!!

tuf-web_co_uk

<?
$script = $_SERVER['SCRIPT_NAME'];
$script = str_replace("/fi_template", "", $script);
?>

i ran the script and found that there was a javascript error you might want to check this out

ts10

That worked. Thanks so much!
