ParticipantDear Support,
I created the WordPress theme where I used custom fields based on meta box plugins. I also included all required plugins (e.g. meta box, meta box groups etc) in my theme. Everything is working fine on my testing site but if only I wanted to install this theme on the new site I am getting warnings and cannot do anything. Please have a look:
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wordpress\wp-content\plugins\meta-box\inc\meta-box.php on line 105
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wordpress\wp-content\plugins\meta-box\inc\meta-box.php on line 77
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wordpress\wp-content\plugins\meta-box\inc\meta-box.php on line 369

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wordpress\wp-content\plugins\meta-box\inc\meta-box.php on line 77
The custom meta boxes I created are in a sub folder in my theme as a part of it. Should I add them as a separate plugin though?
Please help me as I do not know what to do now.
KasiaApril 19, 2018 at 5:23 PM #9277Participantah also those two lines in the end I have:

KeymasterHello,
Can you share the code to register meta boxes? I guess there're some things missed there.
April 19, 2018 at 5:46 PM #9279ParticipantHi Anh 🙂
There you go:
/** * Displaying all custom metaboxes */ add_filter( 'rwmb_meta_boxes', 'lhk_register_home_meta_boxes' ); function lhk_register_home_meta_boxes( $meta_boxes ) { $files_contact = glob( get_template_directory() .'/inc/contact-mod/<em>.php' ); $files_csi = glob( get_template_directory() .'/inc/csi-mod/</em>.php' ); $files_general = glob( get_template_directory() .'/inc/general-mod/<em>.php' ); $files_home = glob( get_template_directory() .'/inc/home-mod/</em>.php' ); $files_how = glob( get_template_directory() .'/inc/how-mod/<em>.php' ); $files_prod = glob( get_template_directory() .'/inc/product-mod/</em>.php' ); $files_post = glob( get_template_directory() .'/inc/post-mod/<em>.php' ); $files_testimonials = glob( get_template_directory() .'/inc/testimonials-mod/</em>.php' ); $all_files = [ $files_contact, $files_csi, $files_general , $files_home, $files_how , $files_prod , $files_post, $files_testimonials ]; foreach ( $all_files as $key => $files ) { foreach( $files as $file ){ $meta_boxes[] = include $file; } } return $meta_boxes; }Thank you 🙂
April 19, 2018 at 5:48 PM #9280ParticipantBy the way I am using TGM Activation Class to include your plugins, if it can help anyhow...
April 19, 2018 at 6:56 PM #9282ParticipantAhn, I am just wondering... If I registered some fields e.g. email filed this way:
[
'id' => 'contact_email',
'type' => 'email',
'name' => esc_html__( 'Email:', 'lhk' ),
'desc' => esc_html__( 'Please insert your email here.', 'lhk' ),
'size' => 50,
],where 'type' is 'email' instead of e.g. 'text' could it caused the problem?
I have a few fields registered as 'type' => 'url' .... when I checked the documentation there are no these types of fields...April 19, 2018 at 8:33 PM #9285ParticipantAs an example I am giving you the code for a one meta box I created. If you wish to see all files please let me know.
All the meta boxes are created in this way:
April 20, 2018 at 3:17 PM #9293KeymasterHi,
I've just checked your code and couldn't see the error. Here is my test:
https://i.imgur.com/GBe6C7B.gif
Probably it's somewhere else. Can you check if there's any meta box that doesn't have any field?
I see you use
globto include all PHP files in a folder. Maybe there's a PHP file that doesn't contain meta box code?April 23, 2018 at 3:51 PM #9318ParticipantHi Anh,
I hope you had a good weekend. Thank you for all your help and concern. I checked everything once again and.... instead of returning each meta box (code) in each file I assigned it to meta boxes array..so in the end, I was trying to nest a meta boxes array in meta boxes array 🙂 I am not sure if I explain it clearly enough 🙂 Long story short, my each file started like this:
$meta_boxes[] = [
'title' => esc_html__( 'Service Testimonials', 'lhk' ),
'post_types' => [
'page',
],.....
etc......and should like this:
return[
'title' => esc_html__( 'Service Testimonials', 'lhk' ),
'post_types' => [
'page',
],......
etc.......
It caused all these errors.Thank you again Anh
Best,
KasiaApril 23, 2018 at 5:46 PM #9320KeymasterHey Kasia, no problem at all. I'm glad you figured it out!
If you need any help, please let me know.
