Completely Stuck on passing snippet property values with a custom snippet

How in the world would I be able to make the form become dynamic so that I can send data to different database tables depending in a selected value from a visitor.

I have a formit form where I set a value with a dropdown.
In my snippet "mycomp" that I hook in the formit call I check for this value.

When the dropdown value is alfa then I want to set some property values (from formit2db) in the formit call.

[[!FormIt?
&hooks=`mycomp,formit2db`
&packagename=`[[+pack]]`
&classname=`[[+class]]`
]]

I tried this in my snippet but the placeholders stay empty.

<?php
if ($hook->getValue('comp_code') == 'alfa' ){
$data = array(
    'pack' => 'Appone',
    'class' => 'ApplicationOne',
);
return $data;
}

I have tried many options like runsnippet etc etc but the placeholders always stay empty.
If anyone has any ideas please let me know because I'm stuck after 8 hours of trial and ERROR.

I don't quite understand what you are trying to do but if you want to set FormIt placeholders in a hook you would use setValues.

E.g (code not tested).

if ($hook->getValue('comp_code') == 'alfa' ) {
	$hook->setValues(array(
		'pack' => 'Appone',
		'class' => 'ApplicationOne',
	));
}

return TRUE;

Hooks should only return TRUE or FALSE IIRC. Also FormIt by default uses the fi. prefix
so your placeholders might be [[+fi.pack]] etc.

Personally I would approach this differently and use Javascript instead, possibly with
AJAX.

From what I gather, with your approach of multiple submits(?), you will need
to use FormItRetriever.

you can do it this way:


<?php

$comp_code = $modx->getOption('comp_code',$_REQUEST,'');

if (!empty($comp_code)){
    
    switch($comp_code){
        case 'alfa':
            $scriptProperties['packagename'] = 'Appone';
            $scriptProperties['classname'] = 'ApplicationOne';
        break;
        //other cases go here
    }
}

$modx->runSnippet('Formit',$scriptProperties);

and call it:

[[!myFormItWrapper?
&hooks=`formit2db`
&otherProperties
]]

Hi All,

Thank you for replying. I managed to get it all working. The issue was that the formitretriever was placed too low on the page.
So now I can write a submitted form to it's own database table based on a selection that somebody made in the form.

I can also retrieve it with rowboat and make a PDF from the dynamically filled page with "client-entry-data".

The last thing I'm stuck on is that the names of the two attached images are written to the database as "array".
But when I try to work in a custom snippet with the placeholder array for one of the attachments I get:

Warning: array_shift() expects parameter 1 to be array, string given

When I print this string I get: 2_photo.jpg,image/jpeg,/tmp/phpCHukqj,0,79537

Is there a way I can retrieve only the name of these images so they get written to the database instead of "array"?

(I'm using formit2file and formit2db with formit.)

I see that the formit2db snippet has a json encoded arrayFields property but how does it work? Is this the solution? Fill in the two attachment placeholders and the name will be stored?
