Dear Sir/Madam,

I have a post type "coupon", it is possible to have two related parents, "merchant" and "advertiser", I want to get the parent title name if existed by adding code in View

Issued By: [wpv-post-title id="$merchant"], [wpv-post-title id="$advertiser"]

Refer to the screenshot, only the coupon springb-01 has parent relationship to merchant and advertiser, all other shows its title name if no advertiser parent relationship, I suppose it should not be shown.

Best regards,

Kelvin.

Dear Kelvin,

It is expected result, if there isn't parent "advertiser" post set, then the shortcode [wpv-post-title id="$advertiser"] will display the current child "coupon" post information.

In your case, you can use [wpv-conditional] shortcode to check if there is any parent "advertiser" post setting, then display the parent advertiser" post title, for example:

[wpv-conditional if="( NOT(empty($(__wpcf_belongs_advertiser_id))) )"]
    [wpv-post-title id="$advertiser"]
[/wpv-conditional]

Dear Luo Yang,

I paste below code

        	[wpv-conditional if="( NOT(empty($merchant)))"]
				[wpv-post-title id="$merchant"]
			[/wpv-conditional]
        	[wpv-conditional if="( NOT(empty($advertiser)))"]
				[wpv-post-title id="$advertiser"]
			[/wpv-conditional]

but still, show the child post title if no parent advertiser

[Luo Yang]

Please try below codes:

[wpv-conditional if="( NOT(empty($_wpcf_belongs_merchant_id)))"]
    [wpv-post-title id="$merchant"]
[/wpv-conditional]
[wpv-conditional if="( NOT(empty($_wpcf_belongs_advertiser_id)))"]
    [wpv-post-title id="$advertiser"]
[/wpv-conditional]

The "_wpcf_belongs_merchant_id" and "_wpcf_belongs_advertiser_id" are hidden custom fields for storing the parent post IDs.

Dear Luo Yang,

I tried to copy and paste your code but the same result.

Best regards,

Kelvin.

Thanks for the details, you are right, please modify the codes as below, and test again:

[wpv-conditional if="([wpv-post-id id='$merchant'] ne [wpv-post-id])"]
[wpv-post-title id="$merchant"]
[/wpv-conditional]
[wpv-conditional if="([wpv-post-id id='$advertiser'] ne [wpv-post-id])"]
[wpv-post-title id="$advertiser"]
[/wpv-conditional]

Above codes will be able to check if the parent post IDs, if they not equal to current child post ID, then display the parent post information.

Dear Luo Yang,

I find my code result is same as yours.

Yours

[wpv-conditional if="( NOT(empty($_wpcf_belongs_merchant_id)))"]
    [wpv-post-title id="$merchant"]
[/wpv-conditional]
[wpv-conditional if="( NOT(empty($_wpcf_belongs_advertiser_id)))"]
    [wpv-post-title id="$advertiser"]
[/wpv-conditional]

Mine

[wpv-conditional if="( NOT(empty($merchant)))"]
	[wpv-post-title id="$merchant"]
[/wpv-conditional]
  	[wpv-conditional if="( NOT(empty($advertiser)))"]
	[wpv-post-title id="$advertiser"]
[/wpv-conditional]
