Passing a url parameter into readfile()

[bobbynovak]

My PHP background is VERY small. I have only used a few very simple functions - ever. That said, I am using the following php as a file I link to. When run, it forces download of a certain page (the page never actually opens in the browser, just downloads) into a word doc. It is working perfectly - except that I need to use a parameter in the readfile() url to filter the resulting file, but the readfile() seems to be ignoring the parameter.

Any suggestions on how I can get the parameter to work? The link to the php file is:

<?php header("Content-type: application/vnd.ms-word"); header("Content-disposition: attachment; Filename=letter_1.doc"); readfile("http://scriptcasemanagement.com/firm-login/letters-forms/ltr-ssa-1696[b]?casenum=$passid[/b]"); ?>

And sorry - my site is password protected containing secure info, so you really can’t go check it out or anything.

I would change the link to:
[php][/php]

[] denotes adding to an array, say if you have 20 checkboxes you could do color[] in order to get them all in the same value array.

On the server side you have to get the variable, it is not magically available
[php]<?php
header(“Content-type: application/vnd.ms-word”);
header(“Content-disposition: attachment; Filename=letter_1.doc”);

if (!empty($_GET[‘id’]) && is_numeric($_GET[‘id’]) {
readfile(“http://scriptcasemanagement.com/firm-login/letters-forms/ltr-ssa-1696?casenum=” . $_GET[‘id’]);
}[/php]

$_GET, $_POST, $_SERVER, $_COOKIE etc are global variables generated by php automagically. You should check them out

Thanks so much JimL - glad I didn’t keep trying to piddle pointlessly with that.

Couple of things, though. So throughout my site, which links a lot of forms and displays together using a common case number, I usually add the parameter “?casenum=[id]” to pull the id of the form entry I am already on and which I want to pass along. Then I use a shortcode [get param=casenum] on the next page to grab it and filter my display. I guess the underlying problem here is that since I have a php function in the middle of this exchange, my link to the page to print is now in a php file, which does not read my “[id]” the same way. So somehow, I need to draw [id] as an actual number into my php function and then put that number on the end of my readfile() url.

$passid should probably be thrown away - I made it up badly for this - it is undefined entirely and only existed in the two places I posted.

I think that might change some nuances in the code you gave me. I saw that I hadn’t explained that clearly, and indeed, when I gave your code a go, I just got a new page with ?id=<?= $passid ?> printed as the end of the url.

Any chance you can clear up my muddling?

Add the code you are working with and we’ll take it from there

Link to php file:

Letter to SSA 1696

PHP file:

<?php header("Content-type: application/vnd.ms-word"); header("Content-disposition: attachment; Filename=letter_1.doc"); readfile("http://scriptcasemanagement.com/firm-login/letters-forms/hbrteyiu92i3jnnhbdo12894euychj9wiounek/[b]?casenum=[id][/b]"); ?>

JimL suggested code:

Link to php:

php:

<?php header("Content-type: application/vnd.ms-word"); header("Content-disposition: attachment; Filename=letter_1.doc"); if (!empty($_GET['id']) && is_numeric($_GET['id']) { readfile("http://scriptcasemanagement.com/firm-login/letters-forms/ltr-ssa-1696?casenum=" . $_GET['id']); } $_GET, $_POST, $_SERVER, $_COOKIE etc are global variables generated by php automagically.
