I posted this question ExpressionEngine, php and stash - scope problem, please help and really appreciate the responses and take on board that mixing ExpressionEngine and PHP tags is bad practice, and also that using embeds in a loop is bad for performance...

I was originally trying to use stash and got to a place where the pdf generation would be blank the first time the user generated it and then every subsequent click to generate it, it would be one generation behind ie if you removed a favourite, it would only be reflected after generating the pdf twice more.

I thought tring to remove stash from the equation might help. However I have a situation where I am needing to extend the ExpressionEngine favorites plugin by having more than one entry on a page able to be favourited - in this case a barristers skills that are related to the barrister currently being viewed by a playa relationship. I have had to use PHP on output to sort through the favourited entry_ids and have the barrister skills listed below each barrister and the client is keen to keep the content that is going into the pdf as ExpressionEngine tags so it is reusable in future projects.

What I am finding with the code below is that I can generate the accurate html code in one click and display it on screen, but if I attempt to do anything else with that variable (generate a pdf) using PHP, the pdf is sent but is made of unparsed ExpressionEngine tags.

My question is - is there any hope for this approach? I really can't think of another way to approach this problem and I am rather stuck! I happily use and pay for an ExpressionEngine plugin to do this but there isn't one out there that can sort through the favourited IDs and work out which are playa parents and format things in the right way and be compatible with Playa and Matrix.

Many thanks in advance for any light anyone can shed on this.

The code:

$barrister_expertise_titles = '{exp:stash:get name="barrister_expertise_titles"}';

$barrister_person_ids = '{exp:stash:get name="barrister_person_ids"}';
$barrister_person_ids = rtrim($barrister_person_ids, ',');
$barrister_person_ids = explode(',', $barrister_person_ids);
$barrister_person_ids = array_unique($barrister_person_ids);
$barrister_person_ids = array_keys(array_count_values($barrister_person_ids)); 

$other_favourites = '{exp:stash:get name="other_favourites"}';
$other_favourites = rtrim($other_favourites, ',');
$other_favourites = explode(',', $other_favourites);
$other_favourites = array_unique($other_favourites);
$other_favourites = array_keys(array_count_values($other_favourites)); 

$barrister_fave_ids =  "{exp:stash:get_list name='barrister_expertise_favourites'}{fave_id}{/exp:stash:get_list}";
$barrister_fave_ids = str_replace("{fave_id}","", $barrister_fave_ids);
$barrister_fave_ids = substr_replace($barrister_fave_ids ,"",-1);
$barrister_fave_ids = str_replace(' ','',$barrister_fave_ids);

$barrister_exploded_fave_ids = explode(',', $barrister_fave_ids);
$barrister_exploded_fave_ids = array_unique($barrister_exploded_fave_ids);
$barrister_exploded_fave_ids= array_keys(array_count_values($barrister_exploded_fave_ids)); 

$num_barrister_faves = sizeof($barrister_exploded_fave_ids);

$html_generation = "";

$i = 0;
$num_barristers = sizeof($barrister_person_ids);

while ($i < $num_barristers) 

    $this_barrister_id = $barrister_person_ids[$i];

        $html_generation .= "{embed='includes/pdf_format_barrister' barrister_id='$this_barrister_id'}";

            while ($j < $num_barrister_faves) { 

                $html_generation .= "{embed='includes/pdf_format_expertise' barrister_id='$this_barrister_id' fave_id='$barrister_exploded_fave_ids[$j]'}";



$html = $html_generation; // html is in this variable and correct if echoed...

// trying to use php to now generate the pdf (the included file below is on the server)
// but it sends a pdf without the expressionengine tags parsed...

The pdf format expertise include is similar to pdf_format_barrister

Have you tried writing a plugin that grabs everything between 2 tag pairs and creates a pdf in the plugin?


{all the stuff}



Not sure if it would work, but shouldn't take too long to try.

Just this week I used mpdf(www.mpdf1.com) to create a pdf from a template with php enabled on output and it worked pretty well, just needed to change some of my html to tables so it would display correctly. So maybe you just try another PDF generator.

If you just want an easy way out, you could look at pdfcrowd.com/ which offers either a link that will create the pdf for you, or they have a browser add-on that will create the pdf with a click.
