[Resolved] Child theme

[Joyce]

Hi Team,

I modified GP theme PHP file (e.g. wp-content/themes/generatepress/comments.php) and every time I upgrade theme, I have to re-do all these changes. I have seen others using child theme, just wondering what is the right way to handle it. Can you pls help to confirm if my understanding is correct?

1) add customized PHP code in child theme and set child theme as main theme (child theme code will overwrite default theme PHP)
2) when upgrade GP theme, upgrade GP theme only, do not touch child theme

Thanks,
Joyce

Hi there,

once the Child theme is installed.
Copy the themes comments.php file into the Child Theme folder.
Make your edits to the Child Themes comments.php

Then you can safely update the Parent theme and keep your changes 🙂

Thanks David, sorry for my late reply.

I follow https://docs.generatepress.com/article/using-child-theme/ and create my own child theme. However the following specific changes in child theme does NOT overwrite parent theme
– /themes/generatepress_child/inc/structure/comments.php
– /themes/generatepress_child/inc/structure/post-meta.php
– /themes/generatepress_child/inc/theme-functions.php
Only /themes/generatepress_child/comments.php works.

I change inc folder permission to be 644 but it’s still the same. Is there a way to fix it?

What changes are you trying to make to the Comments form? It may be possible to use filter hooks instead of overwriting the comments.php

let me know.

Hi David,

Thanks for your reply. I am trying to do the followings

1a) /inc/structure/comments.php
– remove comment url/email input field (I tried to add in function.php and also generatepress/comments.php, but it does not work.

add_filter('comment_form_default_fields', 'url_filtered');
function url_filtered($fields)
{
  if(isset($fields['url']))
   unset($fields['url']);
  return $fields;
}
add_filter('comment_form_default_fields', 'email_filtered');
function email_filtered($fields)
{
  if(isset($fields['email']))
   unset($fields['email']);
  return $fields;
}

1b) /inc/structure/comments.php
– change text (leave a comment, Post Comment) and author label

$defaults['title_reply'] = apply_filters( 'generate_leave_comment', __( 'Change text-Leave a Comment', 'generatepress' ) );
$defaults['label_submit'] = apply_filters( 'generate_post_comment', __( 'Change text-Post Comment', 'generatepress' ) );
<label for="author" class="screen-reader-text">Change text-author label</label>

2) /inc/structure/post-meta.php
– I need to display prev/next post link within one line, so I added css class (prev-post-link,next-post-link)

<'previous_format' => '<div class="nav-previous prev-post-link">' . generate_get_svg_icon( 'arrow-left' ) . '<span class="prev" title="' . esc_attr__( 'Previous', 'generatepress' ) . '">%link</span></div>'
<'next_format' => '<div class="nav-next next-post-link">' . '<span class="next" title="' . esc_attr__( 'Next', 'generatepress' ) . '">%link</span>' . generate_get_svg_icon( 'arrow-right' ) . '</div>'
next-post-link {
	float: right;
	font-weight: bold;
}
.prev-post-link {
	display: inline;  //div do not break into new line
	font-weight: bold;
}

3) /inc/theme-functions.php (home page, open post in new tab)
<h2 class="entry-title"%2$s><a href="%1$s" rel="bookmark" target="_blank">

By default, WordPress only allows the top-level files to be overwritten in a child theme – so that would only be these files you see here:
https://github.com/tomusborne/generatepress

I believe all 3 of your requirements can be done with filters and CSS though.

Can you open a new topic for each of the requests?

Thanks!

Thanks Leo.
