Generating PDF and eForm

Hello,

For my first post, I whish to start by thanking people behind modx for giving us a so valuable tool.

I’m currently working on a HTML -> PDF conversion under ModX Evo 1.05. To do so, I adapted a previous thread. I modified the code in order to use snippets when generating PDFs. Here is the code of my snippet (called GeneratePDF):

<?php
global $modx;

# Define a unique name for each generated PDF
$stamp = time();
$nomFichier = $modx->getLoginUsername() . '_' . $stamp;

# Getting back info generated by modX
if (isset($_GET['docid'])) {
	$id = $modx->db->escape($_GET['docid']);
	$doc = $modx->getPageInfo($id, 1, 'content');
	$title = $modx->getPageInfo($id, 1, 'longtitle');
}
$output = '<h1>' . $title['longtitle'] . '</h1>' . $doc['content'];

# Execute all Snippets present on this page (using TV listeSnippets)
//$listeSnippets = explode(",", &$liste); 

$liste = isset($liste) ? $liste:'';
$listeSnippets = explode(",", $liste);
foreach($listeSnippets as $snippet) {
	$snippetCalls = explode("?", $snippet);
	$nomSnippet = $snippetCalls[0];	
	if ( sizeof($snippetCalls) == 2 ) {
		$paramTous = $snippetCalls[1];
		$interms = explode("&", $paramTous);
		$params = array();
		foreach($interms as $paramInterm) {
			if (trim($paramInterm) != '') {
				$paramInterm = preg_replace('/\`/', "", $paramInterm);
				$interms = explode("=", $paramInterm);
				if (sizeof($interms) == 2) {
					$params[$interms[0]] = $interms[1];
				}
			}
		}
		$output .= $modx->runSnippet($nomSnippet, $params);
	} else {
		$output .= $modx->runSnippet($nomSnippet);
	}
}

# Delete all snippets call that will otherwise be visible into the PDF
$output = preg_replace('/\[!.{1,}!\]/', "", $output);

# Write PDF
$basePath = $modx->config['base_path'];
$pluginPath = $basePath . 'assets/lib/tcpdf/';
if ($_GET['contentType'] == 'pdf') {
	include $pluginPath . 'examples/myexample.php';
}

?>

I created a template variable called "listeSnippets" (tested types: text and rich text). This TV gets the name (and parameters) of the snippets that have to be processed when generating a PDF. For example:

mysnippet, eForm? &formid=`informC` &eFormOnBeforeMailSent=`storeInforme` &tpl=`informC` &noemail=`true`

In my template, I added the snippet call:

[!GeneratePDF? &liste=`[*listeSnippets*]`!]

The PDF is generated correctly, but only the first snippet is processed. When tracing the $liste arg in the snippet, I got: "mysnippet, eFor". Has somebody an idea on why the second snippet call is truncated?

Thanks in advance.
