Featured image for each advert

Hi, i am travelling right now and i wasn’t able to write the snippet yet, but it should be available next week.

In the link below you will find a code snippet which will force a featured image when posting an Ad (using [adverts_add]) or when editing it (from [adverts_manage]).

https://github.com/simpliko/wpadverts-snippets/blob/master/force-featured-image/force-featured-image.php

This code works fine, but the update(0.2.0 – X-Team, Jonathan Bardo) I could not make it work.

I am not sure what do you mean by

update(0.2.0 – X-Team, Jonathan Bardo)

??

Greg, I didn’t get email notification of your reply, so I’ve only recently seen this.

WOW! Thank you! This is perfect! Just what I was after.

Take a look at the essential grids grid I have created in my side bar here. https://www.carshow.life (site is still being build by the way)

Thank you again, it obviously took a fair bit of your time up.

I used this snippet like a plugin.
An update was released (0.2.0).
The author informed is X-Team, Jonathan Bardo
When i updated the script it not work.
Am I doing something wrong?

It seems the add-on name is conflicting with the Force Featured Image https://www.ads-software.com/plugins/force-featured-image/ already available in the repository, you will need to install it again, but change the folder name in which the snippet is to my-force-featured-image or install it in default folder but do not update.

I will try. Thanks Greg.

I know it is a basic question, but how do you use this like a plugin?

I tried uploading the pho file into a folder I created in my plugins folder, but it didnt appear for me to see or activate in the admin dashboard under plugins…

Please see the “Using Snippets” here https://github.com/simpliko/wpadverts-snippets it explains how to do that.

Works fine Greg, thanks.

zzkamikazezz, I did a quick solution that is really much easy.

I named the folder and plugin with “my-force-featured-image” and my-force-featured-image.php respectively, to avoid conflict with existent plugin force featured image, like Greg said.

Put the snippet into the file and create a header plugin, like this:

/*
 * Plugin Name: My Force Featured Image
 * Plugin URI: https://wpadverts.com/
 * Description: This code snippet/plugin forces user to select a featured image or selects it for the user automatically.
 * Author: Greg Winiarski
 */

For some reason the code snippet is not working for me. I tried it as a plugin and using Code Snippets – neither seems to work…

add_filter( "adverts_action_preview", "force_featured_image_add" );
add_filter( "adverts_template_load", "force_featured_image_edit" );
/**
 * Forces featured image when adding new Ad using [adverts_add].
 * 
 * @uses force_featured_image()
 * 
 * @param string $content Page content
 * @return string
 */
function force_featured_image_add( $content ) {
    
    $post_id = adverts_request("_post_id", null);
    force_featured_image( $post_id );
    
    return $content;
}
/**
 * Forces featured image when editing and Ad in [adverts_manage].
 * 
 * @uses force_featured_image()
 * 
 * @param string $path Path to template file
 * @return string
 */
function force_featured_image_edit( $path ) {
    
    if( basename( $path ) == 'manage-edit.php' && isset( $_POST['_post_id'] ) && is_numeric( $_POST['_post_id' ] ) ) {
        force_featured_image( $_POST['_post_id'] );
    }
    return $path;
}
/**
 * Sets featured image for $post_id
 * 
 * @param int $post_id  ID of a post for which we wish to force featured image
 * @return int          1 if success less or equal to 0 on failure
 */
function force_featured_image( $post_id ) {
    if( $post_id < 1 ) {
        // No images uploaded
        return -1;
    } else if( $post_id > 0 && get_post_thumbnail_id( $post_id ) ) {
        // Has main image selected
        return -2;
    } 
    
    $children = get_children( array( 'post_parent' => $post_id ) );
    
    foreach( $children as $child ) {
        update_post_meta( $post_id, '_thumbnail_id', $child->ID );
        return 1;
    }
    
    return 0;
}

This code is executed on preview, you will need to add some debugging code in function force_featured_image() to see if it is being executed and what happens on execution.
