[Resolved] How to display the child value in a parent (list) view?

[Author]

I am trying to: Display the value of a child field (there is always one child with the parent)

I visited this URL: https://toolset.com/documentation/user-guides/displaying-related-child-posts/#3

I expected to see: the raw value of the field

Instead, I got: nothing

this is part of my code in the Template for this View / loop item (item = parent)

***

[wpv-conditional if="( '[has_children_of_type post_type="testimonial" ]' eq '1' )"]
[types field="option" output="raw"][/types]
[/wpv-conditional]

***

"option" is a child-field in testimonial.

p.s.
I can not use the child-fields in the parent-type. The parent has to show always, the child value only appears when a payment is completed.

Hello. Thank you for contacting the Toolset support.

To check if parent post has child post-field you need to add custom shortcode/function to check. Please refer to the following documentation:
=> https://toolset.com/documentation/user-guides/querying-and-displaying-child-posts/

For example, What you can do is to create a Custom ShortCode where you perform a check if parent post has child post.

You can also use the Types API to build this query, such a ShortCode can look like this:

function child_exists_func( $atts ){
$child_posts = types_child_posts('your-child-post-type-slug-here');
if ($child_posts) {
return true;
}
}
add_shortcode( 'child-exists', 'child_exists_func' );

Where:
Replace 'your-child-post-type-slug-here' with your child post slug.

This above ShortCode would be used on the PARENT post type and returns true if a Child exists.
Of course, you can extend this to return the ID, or whatever you want of the Child Post
Also, you should include a case for if no child exists, as example you can return false.

This ShortCode can then be registered in Views > Settings and be used in the Views Conditional Output.
https://toolset.com/documentation/user-guides/shortcodes-within-shortcodes/ >Third-party shortcode arguments

I hope this solution will help you to resolve your issue.

I already did this and this is working:
"For example, What you can do is to create a Custom ShortCode where you perform a check if parent post has child post."

otherwise this condition wasn't working:
[wpv-conditional if="( '[has_children_of_type post_type="testimonial" ]' eq '1' )"]

What do you mean by "Of course, you can extend this to return the ID, or whatever you want of the Child Post"

I'm looking for something inside the wpv-conditional to display the value of a child-field. And this is the part I have problems with.

What do you mean by "Of course, you can extend this to return the ID, or whatever you want of the Child Post"
=> I mean to say currently we return 'true' or 'false' based on the condition that if post has child or not. You can return any value based on your requirement.

I think you should refer to following documentation that may help you:
=> https://toolset.com/documentation/user-guides/conditional-html-output-in-views/using-custom-functions-in-conditions/
=> https://toolset.com/documentation/user-guides/conditional-html-output-in-views/using-shortcodes-in-conditions/

[mcjS]

I read the documentation, but I don't see a sample of something like

[wpv-conditional if="( '[has_children_of_type post_type="testimonial" ]' eq '1' )"]
display the child-value of the child-field-option
[/wpv-conditional]

I know wpv-conditional is given true and then I want to display a child-value.
is it something like
[types child-field="option" output="raw"][/types]
?

i'm not a php coder , so I'm looking for help to make my code working.

Could you please share problem URL as well as which view you are using?

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).

I have set the next reply to private which means only you and I have access to it.

Could you please let me know the complete range of this condition:

IF there is a child (AANMELDING)
display the field option (value)
if the child-field option = 5104 then display "zaterdag"
if the child-field option = 5106 then display "zondag"
.etc
.etc
.etc
if the child-field option =7625 then display "zaterdag en zondag"
END

means how many combinations you have lets say "child-field option = 5104 then display "zaterdag""
then if child field option = xx then display yyyy.

[mcjS]

if the child-field option = 5104 then display "zaterdag 30 april"
if the child-field option = 5106 then display "zondag 1 mei"
if the child-field option = 5107 then display "zaterdag 30 april en zondag 1 mei"
if the child-field option = 5144 then display "zaterdag 30 april"
if the child-field option = 5145 then display "zondag 1 mei"
if the child-field option = 5146 then display "zaterdag 30 april en zondag 1 mei"
if the child-field option = 5147 then display "zaterdag 30 april en zondag 1 mei"
if the child-field option = 7622 then display "zaterdag 30 april"
if the child-field option = 7623 then display "zondag 1 mei"
if the child-field option = 7624 then display "zaterdag 30 april en zondag 1 mei"
if the child-field option = 7625 then display "zaterdag 30 april en zondag 1 mei"

this is the complete list.

Can you give me information about the status?
When I take a look now, the (incomplete) message wich worked before, isn't showing anymore?

[wpv-conditional if="( '[has_children_of_type post_type="aanmelding" ]' eq '1' )"]
<div class="blue">some text</div>
[/wpv-conditional]

Hi there,

FTP access details are not working at this end. Could you please resend it to me.

[Minesh Supporter Languages: English (English ) Timezone: Asia/Kolkata (GMT+05:30)]

When I tried to access the view you shared with me before it says its been deleted:
hidden link

Could you please tell me which view I should look? and which is your problem URL now?

[mcjS]

hidden link
(Templates for this View) = hidden link = homepage
and
hidden link
(Template) = when you click on "lees meer" = more information at an ad.

Excuse me, but I had to work on it by the weekend.My mistake.

[Minesh Supporter Languages: English (English ) Timezone: Asia/Kolkata (GMT+05:30)]

Could you please check now. I've modified the code in your functions.php file as given under:

function has_children_of_type( $atts ) {
    global $post;
    extract( shortcode_atts( array(
        'post_type' => 'advertentie', // Make sure to set the correct post type
    ), $atts ) );
    $parent_type = $post->post_type;
    $childargs = array(
        'post_type' => $post_type,
        'numberposts' => -1,
        'meta_query' => array( array( 'key' => '_wpcf_belongs_'.$parent_type.'_id', 'value' => $post->ID ) )
    );
    $child_posts = get_posts( $childargs );
	if(count( $child_posts )){
		
		$x_value = array('5104'=>'zaterdag 30 april',
						 '5106'=>'zondag 1 mei',
						 '5107'=>'zaterdag 30 april en zondag 1 mei',
						 '5144'=>'zaterdag 30 april',
						 '5145'=>'zondag 1 mei',
						 '5146'=>'zaterdag 30 april en zondag 1 mei',
						 '5147'=>'zaterdag 30 april en zondag 1 mei',
						 '7622'=>'zaterdag 30 april',
						 '7623'=>'zondag 1 mei',
						 '7624'=>'zaterdag 30 april en zondag 1 mei',
						 '7625'=>'zaterdag 30 april en zondag 1 mei',
						 
						 
						 );
			
		
		$x = get_post_meta($child_posts[0]->ID,'wpcf-optie',true);
		if(is_numeric($x)){
			return $x_value[$x];
		}
			
		
	}
    //return count( $child_posts ) == 0 ? false : true; 
}
add_shortcode( 'has_children_of_type', 'has_children_of_type' );

And I've called it above shortcode from your view template as given under:

[has_children_of_type post_type="aanmelding" ]

[mcjS]

The problem now is: every ad is showing the standard custom text (blue "highlighted") it is only needed when there is a child. Otherwise it is wrong to show the standard custom text.

I'm missing now the wpv-conditional in the view?

[wpv-conditional if="( '[has_children_of_type post_type="aanmelding" ]' eq '1' )"]
<div class="blue" style="margin-top: 9px">standard custom text (plus the option description)</div>
[/wpv-conditional]

I mean with "(plus the option description)" the value of the array.
