Problem using data received from CCv5 in CFv5 custom field

Question

Hi,

I have a problem with using form data in a Custom field. Here's the lay of the land:

- The app is a materials catalog
- I have a table 'DBMAT_materiaal' in the same DB as Joomla with all the articles.
- I made a Connection with a Frontend-list in CCv5 using that table; modelname is 'mat'
- The field 'omschrijving' is linked to CFv5 form 'materiaal-edit'
- Created CCv5 form 'materiaal-edit' with fields that have fieldname and field-id 'mat[fieldname]'
- Linked the form save action back to the CCv5 connection

Form works fine, able to edit and save data.
So far, so good.

I have one field in the form called 'mat[afbeelding]'. In that field is the filename of an image of the article in question.
The image is stored in the images/materiaal/ folder

If the above mentioned field is filled, i want to show the image in the form. To do that is created a custom field in the form with this code:


<?php
if ( isset($form->data['afbeelding']) && $form->data['afbeelding'] ) {
  echo "<img src='".JURI::root()."images/materiaal/".$form->data['afbeelding'].".jpg' style='max-width:200px' />";
} else {
  echo "<img src='".JURI::root()."images/materiaal/no_image_small.png' style='max-width:200px' />";
}
?>

But somehow this is not working. The no-image-small.png image is shown. Also, if i remove the if..then..else clause and just put the first echo line in, there is a broken image icon shown. Looking at the source of the rendered page i can see that the field content is not read, so the img tag ends with ...images/materiaal/.jpg which ofcourse is not a correct name.

I also tried to change

$form->data['afbeelding']

to

$form->data['mat[afbeelding]']

but to no avail.

Does anyone have any ideas?

Kind regard,

Hi Ronald,

I think that you need $form->data['mat']['afbeelding'] and I would simplify the syntax a little by using

<?php
if ( !empty($form->data['mat']['afbeelding']) ) {
  $image = $form->data['mat']['afbeelding'].'.jpg';
} else {
  $image = 'no_image_small.png';
}
$url = JURI::root().'images/materiaal/'.$image;
echo "<img src='{$url}' style='max-width:200px' />";
?>
