Child Theme – functions.php

  • Hi folks,

    I recently started my first WordPress blog, making alterations by tweaking the style.css functions.php files etc directly, however after reading time and again that you should be rocking a child theme, I figured before investing too much time, I should go down that avenue.

    (note: I’ve done a clean install)

    So, I now have a Twenty Twelve child theme, it seems to be running fine, I’ve got my first bit of code in the style.css file and that seems to be working a treat. However I’m struggling with functions.php and content.php.

    For example, to remove the “This entry was posted in …” text from each post, I was using this code in my functions.php file:

    https://pastebin.com/0XNw9VMb

    Compared to the unmodified version which looks like this:

    https://pastebin.com/J641gXFp

    From what I can gather, because I’m looking to change a function, rather than add a new one, I need to use a different technique, is that right? I hope that makes sense, I’m a complete WordPress / coding novice, but I’m trying to make an effort to get this thing running the ‘proper’ way.

    Thanks in advance.

  • What is it exactly you are trying to do?

    Functions in the child theme will modify current theme or core files via hooks and filters. You will usually see this in the form of:

    add_filter()

    or

    remove_filter()

    It’s not a method of simply copying and pasting a function from the parent theme into the child theme and modifying it. Instead, you have to write a new function (with a new name) and modify the content from there using a hook or filter.

    Here is a GREAT place to learn!

    Hi Josh,

    Please excuse my ignorance, this is all totally new and confusing for me.

    So, using my example above, I want to use my child theme’s function.php file to remove some of the meta (?) info at the end of each post.

    I know what code is responsible for generating it and in turn what I need to remove, but I’m unsure how I go about that when using a child theme.

    Hopefully that makes a bit more sense.

    Hmmm… this might be easier with CSS… if your theme is setup that way.

    What’s the url to a page where you want to remove this content?

    I want to make the meta info change as mentioned above and move the “leave a reply” link to after the post.

    Okay… to remove the aforementioned text.. add this to your stylesheet (style.css) file.. at the very bottom on a new line:

    footer.entry-meta {
    display: none;
}

    Unfortunately, the leave a reply is going to require modifying theme files. I’m not sure if you can “grab” it in the loop. I don’t think so. I believe that part is hard-coded into your theme using HTML.

    You would need to remove the <div class="comments-link"> out of the <header> part of the template and add it to the <footer> part of the template.

    Thanks for helping.

    If I wanted to keep just the date in the meta info, would that be possible?

    [No bumping, thank you.]

    Nope… again, sorry.

    The CSS is written to display that entire meta info in a single class. Only the entire class can be targeted via css.

    See.. that content isn’t written into the loop. It’s added after the loop is executed. Hence, the hard-coded HTML. I’m honestly not sure if you can modify this info via a function from the child theme.

    Does your theme have a support forum where you can ask?

    It’s the semi-official WordPress theme, but from my understanding, it’s not long been released. I can make all the changes I want by directly modifying the functions.php file, but I was hoping I could do it through the child theme.

    I appreciate all your help.

    [not a bump, this is an update]

    I’m looking through the comments in function.php of the parent theme and it states the following about the meta tag.

    if ( ! function_exists( 'twentytwelve_entry_meta' ) ) :
/**
 * Prints HTML with meta information for current post: categories, tags, permalink, author, and date.
 *
 * Create your own twentytwelve_entry_meta() to override in a child theme.

    So, that means I can create my own function called twentytwelve_entry_meta and it will automatically take priority, is that right?

    Yes… very good. That should be how it works.
