RE: [PHP] Javascript var to PHP

2002-12-18 Thread Jon Haworth 
Hi Cesar,

 I want one of my links to open a brand-new 
 pre defined window using a javascript 
 but I don't know how to pass a variable so 
 the opened PHP file knows which info to get 
 from MySQL... 

In your launchinfopage() function, presumably you're specifying the url of
the page (foo.php or something)?

If so, just tack the variables on the end of the url as normal:

  foo.php?varname=varvalue

And then, in foo.php, look in the $_GET array:

  echo varname is . $_GET['varvalue'];

I do this quite a lot, I can go and dig up the code if you're still having
problems.

Cheers
Jon

Jon, thanx for the fast response, but the problem is that the link is
made dynamically from a DB and the varvalue changes on every link... if
it helps, I make this link list with a FOR loop in PHP and the varvalues
I want to pass are the IDs of a table elements.

You probably need to do it along these lines:

// assume ids are in $id[1...10]
for ($i = 1; $i = 10; $i++) { 
  echo 'a href=javascript:lauchinfopage(';
  echo $id[$i];
  echo ')click for more info/abr /;
}

and, in your JS function:

function launchinfopage(id)
{
  url = infopage.php?id= + id;
  // open url however you like
}

I imagine you have your url hardcoded in your launchinfopage() function...
this makes it less portable, you may want to consider passing the complete
url to a generic open new window function.

Actually Jon, the IDs are not exactly expressed that way, but your
example gave me a nice idea... To tell you the truth (and now that I
have a clearer idea of what to do), the id I need to pass along is from
a random quote (or FAQ) but I'll fetch it before script is being
declared (even before the HTML tag) and then target the script to a
moreinfo.php?var=varvalue page... (does that make any sense?)

thanks a lot.
