Tell us what you are trying to do?

Hi Waqar,

sorry that I have to claim you again. The code you gave me to add the total number of checked boxes in each categorie is not working.

add_action('cred_save_data','func_connect_child_posts',15,2);
function func_connect_child_posts($post_id,$form_data) {
   if ($form_data['id']==339) {
 
        $field-1 = $_POST['wpcf-count-checkboxes-auto-verkehr'];
        $field-2 = $_POST['wpcf-count-checkboxes-bauen-renovieren'];
        $field-3 = $_POST['wpcf-count-checkboxes-behoerden-verbaende'];
 
        $sum = $field-1 + $field-2 + $field-3;
 
        update_post_meta($post_id, 'wpcf-count-checkboxes-gesamtzahl', $sum);
    }
}  

There is an error message in the "Custom code snippets - Settings" and the the field "count-checkboxes-gesamtzahl" remains empty in the form:

[2020-10-12 13:01:41, frontend] syntax error, unexpected '=' in /homepages/15/d845764028/htdocs/clickandbuilds/FirmeninfoRegional/wp-content/toolset-customizations/count-checkboxes-total.php on line 15.
A problem occurred when executing snippet "count-checkboxes-total". The result of include_once is: ""

(I've attached a screenshot of the error message)

I've tried something out myself but couldn't come up with a solution. Hope you can help me again.

Is there any documentation that you are following?

Thank you in advance for your further help.

Hi Jenny,

Thanks for writing back and I apologize for the trouble.

I shouldn't have used "-" characters in the field name variables, in my example snippet.

add_action('cred_save_data','func_connect_child_posts',15,2);
function func_connect_child_posts($post_id,$form_data) {
   if ($form_data['id']==339) {
  
        $field1 = $_POST['wpcf-count-checkboxes-auto-verkehr'];
        $field2 = $_POST['wpcf-count-checkboxes-bauen-renovieren'];
        $field3 = $_POST['wpcf-count-checkboxes-behoerden-verbaende'];
  
        $sum = $field1 + $field2 + $field3;
  
        update_post_meta($post_id, 'wpcf-count-checkboxes-gesamtzahl', $sum);
    }
}

regards,
Waqar

Hi Waqar,

thanks for correcting the code. I completely overlooked that.
The error message has disappeared. But the field "count-checkboxes-gesamtzahl" always outputs a 0 (Screenshot)
Here is the full code that I am using. Is there anything wrong?
I used the same Form-ID 352 for the new part of the code (this is the form where you can tick the checkboxes).

add_action('cred_save_data','func_connect_child_posts',15,2);
function func_connect_child_posts($post_id,$form_data) {
    if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-auto-verkehr'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-auto-verkehr', sizeof($_POST['wpcf-checkboxes-auto-verkehr']));
        }
    }

    if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-bauen-renovieren'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-bauen-renovieren', sizeof($_POST['wpcf-checkboxes-bauen-renovieren']));
        }
    }
  
  
   if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-behoerden-verbaende'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-behoerden-verbaende', sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']));
        }
    }
  
  
   if ($form_data['id']==352) {
   
        $field1 = $_POST['wpcf-count-checkboxes-auto-verkehr'];
        $field2 = $_POST['wpcf-count-checkboxes-bauen-renovieren'];
        $field3 = $_POST['wpcf-count-checkboxes-behoerden-verbaende'];
   
        $sum = $field1 + $field2 + $field3;
   
        update_post_meta($post_id, 'wpcf-count-checkboxes-gesamtzahl', $sum);
    }

}

I am so grateful to you for your help.

regards,
Jenny

Hi Jenny,

The values for the fields "wpcf-count-checkboxes-auto-verkehr", "wpcf-count-checkboxes-bauen-renovieren" and "wpcf-count-checkboxes-behoerden-verbaende" are not available directly from the form, which is why they are not available in global variable "$_POST".

You'll need to get them the same way as for the "update_post_meta" functions:

add_action('cred_save_data','func_connect_child_posts',15,2);
function func_connect_child_posts($post_id,$form_data) {
    if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-auto-verkehr'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-auto-verkehr', sizeof($_POST['wpcf-checkboxes-auto-verkehr']));
        }
    }
 
    if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-bauen-renovieren'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-bauen-renovieren', sizeof($_POST['wpcf-checkboxes-bauen-renovieren']));
        }
    }
   
   
   if ($form_data['id']==352) {
        if(!empty($_POST['wpcf-checkboxes-behoerden-verbaende'])) {
                update_post_meta($post_id, 'wpcf-count-checkboxes-behoerden-verbaende', sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']));
        }
    }
   
   
   if ($form_data['id']==352) {
    
        $field1 = sizeof($_POST['wpcf-checkboxes-auto-verkehr']);
        $field2 = sizeof($_POST['wpcf-checkboxes-bauen-renovieren']);
        $field3 = sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']);
    
        $sum = $field1 + $field2 + $field3;
    
        update_post_meta($post_id, 'wpcf-count-checkboxes-gesamtzahl', $sum);
    }
 
}

Hi Waqar,

Sorry for my late answer. I tested your code and it works great now. Thank you for your great support on my issue.

I have one last question on this subject. I would like to calculate a price for the number of checkboxes and output it in the field "price-checkboxes".

    ...
   $price = ($field1 + $field2 + $field3)* 1.80;
   update_post_meta($post_id, 'wpcf-price-checkboxes', $price);

The script calculates correctly and gives me an output like this e.g. 23.468.

Is there a possibility with the PHP script to round the number to two decimal places and to replace the comma with a point (German spelling). So that the output looks like this 23,47. I've tried something like this but it doesn't work 🙁

   if ($form_data['id']==352) {
     
        $field1 = sizeof($_POST['wpcf-checkboxes-auto-verkehr']);
        $field2 = sizeof($_POST['wpcf-checkboxes-bauen-renovieren']);
        $field3 = sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']);
     
        $price = ($field1 + $field2 + $field3)* 1.80;
        $price = str_replace(".",",", $price);
        var_dump(round($price, 2));
     
        update_post_meta($post_id, 'wpcf-price-checkboxes', $price);
    }

Hope you can help me with this one last time.

Regards and a big thank you,
Jenny

Hi Waqar,

I managed to round the number to two decimal places with this code:

 if ($form_data['id']==352) {
     
        $field1 = sizeof($_POST['wpcf-checkboxes-auto-verkehr']);
        $field2 = sizeof($_POST['wpcf-checkboxes-bauen-renovieren']);
        $field3 = sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']);
     
        $price = (($field1 + $field2 + $field3 - 1)* 1.80 + 85.00)*0.16;
        $pricerounded = round($price, 2);
     
        update_post_meta($post_id, 'wpcf-geamtpreis-checkboxen', $pricerounded);
    }

Can I also output it so that it fills both decimal places with 0?
For example: 10.30 or 10.00

And replacing the point with a comma still doesn't work.
I try to add something like this to the code but than the output field stays empty.

...
$pricecomma = str_replace(".",",", $pricerounded);

update_post_meta($post_id, 'wpcf-geamtpreis-checkboxen', $pricecomma);

Hi Jenny,

Thanks for the update and glad that my message helped.

You can perform the rounding and formatting with ",00", in the same line, like this:

$pricerounded = round($price).',00';

Hi Waqar,

thank you for your answer.
I've tried your suggestion, but the output field remains empty 🙁

if ($form_data['id']==352) {
     
        $field1 = sizeof($_POST['wpcf-checkboxes-auto-verkehr']);
        $field2 = sizeof($_POST['wpcf-checkboxes-bauen-renovieren']);
        $field3 = sizeof($_POST['wpcf-checkboxes-behoerden-verbaende']);
     
        $price = ($field1 + $field2 + $field3 - 1)* 1.80 + 85.00)*0.16;
        $pricerounded = round($price).',00';
       
     
        update_post_meta($post_id, 'wpcf-geamtpreis-checkboxen', $pricerounded);
    }

[Jennifer]

Hi Waqar,

You gave me an idea. I found a solution to fill the decimal places with 0.
Now my output looks like this e.g. 11.00

        $pricerounded = number_format(round($price, 2), 2);

Now my only problem is to replace the point with a comma.
I've tried something like this but then the output field remains empty and i don't understand why.

$pricerounded = number_format(round($price, 2), 2, ',', '.');

Hope we can also find a solution for that ; )

Regards,
Jenny

Hi Jenny,

In your second last message's code snippet, I noticed that an opening bracket is missing at line# 8 , which should throw a PHP error:

$price = (($field1 + $field2 + $field3 - 1)* 1.80 + 85.00)*0.16;

As for the next line (line# 9) that I suggested, it should work for the rounding and formatting part.

I'll recommend to test it again and use value debugging at each line to see at which point it is failing.

regards,
Waqar
