Hide element in pdf

[nobilebarabba]

Hi, I need to hide some elements only in the pdf output when the content equals certain text, how can I do that?
For example, when I select the text "hide" in a dropdown element I need that element would be ignored in the pdf.

First you have to create a custom template, copy the templates folder and rename it. How to do it read here.

Maybe you can add some jQuery to change element style if condition is true. - I did not try but it should be work.
or
if you familiar with PHP, HTML and CSS you can create custum tempalte from scratch. It is not too hard

thank you, I am a newbei and I had try with default.php but I can't understand how call and manage a single element
$this->elements = $group->elements;
echo $this->loadTemplate($group->tmpl);

can you help me?

Well, my pdf templats are usually a form with a specific content and format. I include only those elements in the template that I show in the printout, I omit the other elements.

All you need is to chenge defalut.php to something like I described in this post

Of course this is not the ene and only way to create pdf template but it is easy and works fine for me. Just search this forum...you can find a lot usfull tips, hints and code examples.

ok, now I know how to create a custom template but this code not work, DIV does not hide in pdf template

<?php
$element = $this->groups['group1']->elements['element1'];
?>
<div <?php if ($element->element == '-') echo " class='display-none';"; ?>>
<?php echo $element->element;?>
</div>

In Fabrik Options/Debugging set Debug PDF=yes.
This will display the generated HTML (which is otherwise used for creating the PDF) on your screen and you can inspect with your browser console what you get.

Additionally your can var_dump($element) to see if $element->element is really '-' . Depending on your element type and settings it may be also e.g. a link. Maybe you need to use $element->element_raw ...

BTW: If you don't want to display the element you can just skip it instead of hiding via CSS.

 

[nobilebarabba]

The output is really "-".
I can't do it via CSS because I need to hide elements only if the content is "-".
It is selected time after time in the form (dropdown menu).

 

[troester]

inspect with your browser console what you get.

 

[nobilebarabba]

I get "-"
I tried to change the value with another word but the result Is the same
Maybe I have to call the element in a different way...

 

[troester]

Do you get class='display:none;'?
Is it hidden on the screen?
A displayed "-" may also be a <a...>-</a> or include a non-printable character or some other HTML tag...

 

[nobilebarabba]

No, nothing more then -
I'm try to verify the output element and the condition but it doesn't works
<?php if ($element->element == '-') echo $element->element; else echo 'DIFFERENT' ?>
It shows "DIFFERENT" every time

 

[troester]

Obviously ($element->element == '-') is false.
Did you try to var_dump?
Did you inspect your page source code?

 

[nobilebarabba]

var_dump return

string(99) "
-
"

 

[troester]

string(99)

So it's obviously not only '-' but 98 additional characters.
As I said:

[nobilebarabba]

sorry but I don't understand why the element is not the text selected in the dropdown menu...

 

[troester]

Please read the answers before posting

Depending on your element type and settings it may be also e.g. a link. Maybe you need to use $element->element_raw ...

 

[nobilebarabba]

carfully read again what troester wrote:

AGAIN -> you can get element value in different ways and is also depending whitch type of element is:

$element = $this->groups['group1']->elements['element1'];
or
$element = $this->groups['group1']->elements['element1_raw']; // raw data
or
$element = $this->groups['group1']->elements['element1_ro']; // read only

For dropdown element I would use element_raw to get value
