simple string question

[RickyD77]

ok i have a page name like this

picpop.php?id=P00206

so i need a code like this to check the page name

if (($HTTP_SERVER_VARS['PHP_SELF'])=="/picpop.php"){

echo "this";

}

how to check this string for a thrue result

scuse my english

I don't know what you are trying to say. PHP_SELF cuts off everything after the ? in filename.php?id=1048039

So if you did $PHP_SELF on this, it would return filename.php, not filename.php?id=1048039

Does this answer your question or am I way off on this one?

It's $id we're after.

if($HTTP_GET_VARS['id']){ // simple check to see if $id was passed in the query string.

echo $HTTP_GET_VARS['id'];

}

You could go further and do additional testing on the variable, such as making sure it isn't empty.

if i want the result whit the variable like this
/picpop?id=5

what can i do???

Oh if your trying to get everything after then you would have to do what he said.

Like if you were re-linking to a dynamically created site,

you would do

<a href="<?=$PHP_SELF?id=$id;?>">Click Here!</a>

Of course, just like he said, you might want to do some variable testing before you do this. Like if you weren't sure how many variables are in the address, you might have to test which ones are true (ne), and add those to the end of the statement. This could easily be accomplished with an if statement or something of that sort.

Well, not sure why you want the file name when that's where you already are but you could set something up along the lines of...

echo $HTTP_SERVER_VARS['PHP_SELF']."?id=".$HTTP_GET_VARS['id'];

Mine is not to question why....
