Assuming you're using Revo (not sure with Evo) Why don't you do

require('path/to/your/php/code/mysnippet.php')

If your snippet code is directly in modx you can copy/paste it in a static file, and make the snippet static...
Hope this helps
Cheers

hi,

agree with anso, i do this quite often in evo when i need a script than can be used as a snippet and in a module for example
the same for classes (i often use functions from the class a module rely on in a snippet) and it seems the easiest way to deal with this

hi,

yes, in your case, it would probably be in the assets/snippets/ directory but, actually, you can put the file wherever it sounds logical to you and then call it in your require statement with a simple

require_once MODX_BASE_PATH."assets/snippets/your_snippet_directory/your_file.php";

for example

by the way, this is very useful in many occasions when you need functions to be declared in your snippet
a snippet has great chances to be called many times in a page/ressouce and this would cause a function re-declaration error, using require_once and a distant file will avoid this

thank you sir. but I've got this error

Warning: require_once(MODX_BASE_PATHassets

Fatal error: require_once() [function.require]: Failed opening required 'MODX_BASE_PATH

Did I put my snippet in a wrong place?

By the way I use link path and declare it this way

<li><a href="assets/link/to/myfile/filename.php" target="_blank">Text here</a></li>
</ul>

and my filename.php is

<?php
require_once MODX_BASE_PATH."assets/directory/pdf.php";

I'm not 100% clear on what you're doing, but I think what you want to do is put your code in a MODX snippet (call it MakePdf). Have your code create the .pdf file and return the URL to it.

Then on your page:

Revolution:

<li><a href="[[!MakePdf]]" target="_blank">Text here</a></li>

Evolution

<li><a href="[!MakePdf!]" target="_blank">Text here</a></li>

If you'll be creating multiple .pdf files with the snippet, you can send information to the snippet by using properties in the snippet tag.

Greetings to you Sir Bob, I'm so sorry for that..I'm using Modx revo and just upgraded to 2.2.4..

<li><a href="assets/pdf_folder/my_pdf1.php" target="_blank">text here</a></li>

and in my my_pdf1.php, I have

require('assets/pdf_folder/pdf.php');

and it has 

$pdf->PrintChapter(1,'','math.txt');

it its latter part.

my problem is where to put these stuffs and connect them all:

math.txt
my_pdf.php
pdf.php

thank you . [ed. note: claro_santiago last edited this post 14 years, 3 months ago.]

If you create a MODX snippet that contains the code of the my_pdf1.php file and change the 'include' statement to give the path to the other file, it should work as I suggested above. The second file can go anywhere as long as you get the path right.

I'm not sure about the math.txt file, but there's good chance that it will work if it's in the same directory as the other file.

I tried this code and it went well:

<li><a href="[[!MakePdf]]" target="_blank">Text here</a></li>

the problem is modx can't find math.txt even if there are in the same directory.

Warning: file_get_contents(math.txt) [function.file-get-contents]: failed to open stream: No such file or directory in ....
