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. http://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://wordpress.org/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 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.
