Search Results for 'child theme how to functions.php'

Hi there,
I’ve noticed that the CSS and Javascript are loaded on every site page as well as other all other plugin’s CSS and JS. It’s resource wasting because it requires several TCP connections at every page load and degrading this way the site load performances and the user experience too. Therefore I’m trying to deregister CSS and Javascript where not needed and to load them only on pages where they are needed. For example, since the Contact Form 7 is used only on the ‘contacts’ page, I’ve added the following lines to Newsmag-child theme functions.php:

add_filter( 'wpcf7_load_js', '__return_false' );
add_filter( 'wpcf7_load_css', '__return_false' );
?>

Now, I should add the following lines in the page where the Contact Form 7 is used i.e. “contacts” page:

<?php
    if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {
        wpcf7_enqueue_scripts();
    }
 
    if ( function_exists( 'wpcf7_enqueue_styles' ) ) {
        wpcf7_enqueue_styles();
    }
?>

But I don’t have a “contacts.php” page! So that where I have to add this code?
More in general, could you advice a method by means of which I can always include CSS and JS (mainly due to plugins) only where needed?
Thanks in advance for any appreciated help.

I am trying to add a few custom image sizes inside the functions.php of the child theme. I add the code below and then run Regenerate Thumbnails on an image, but it doesn’t create any of my custom image sizes. I know the plugin is working because if I delete one of the existing thumbs, it recreates it.
Am I doing something wrong?

function custom_image_sizes() {
	add_image_size("custom-thumb", 218, 125, true);
	add_image_size("custom-large-thumb", 290, 166, true);
	add_image_size("custom-medium", 532, 304, true);
	add_image_size("custom-slider", 700, 400, true);
}
add_action('after_setup_theme', 'custom_image_sizes', 11);

Hi,
I use Contact Form 7 plugin in order to get the contact form (please see 43b.60a.myftpupload.com/contatti/). To avoid to get extra CSS and/or JavaScript file on every page of my site, I’ve followed this guide http://code.tutsplus.com/articles/optimizing-contact-form-7-for-better-performance–wp-31255. This way I should get the CSS and Javascript of Contact Form 7 plugin loaded only into the page where the form is really placed.
So that I’ve created a new functions.php file of my Newsmag-child theme which contains only the following code:

<?php
/*
GSM:file functions.php of the Newsmag-child theme
*/
if (!function_exists('aa_deregister_styles')) {
// Deregister Contact Form 7 styles
add_action( 'wp_print_styles', 'aa_deregister_styles', 100 );
function aa_deregister_styles() {
if ( ! is_page( 'contatti' ) ) {
wp_deregister_style( 'contact-form-7' );
}
}
}

if (!function_exists('aa_deregister_javascript')) {
// Deregister Contact Form 7 JavaScript files on all pages without a form
add_action( 'wp_print_scripts', 'aa_deregister_javascript', 100 );
function aa_deregister_javascript() {
if ( ! is_page( 'contatti' ) ) {
wp_deregister_script( 'contact-form-7' );
}
}
}
?>


But, after this I got the following error:

Warning: Cannot modify header information – headers already sent by (output started at /home/content/p3pnexwpnas10_data03/26/2630926/html/wp-content/themes/Newsmag-child/functions.php:26) in /home/content/p3pnexwpnas10_data03/26/2630926/html/wp-includes/pluggable.php on line 1207

What I’m doing wrong?
Thanks

Hi,

I am using Newspaper 6 Theme.

On category pages we have filter passed in query string which is post tag. So want to filter my posts according to that query string tag.

So I have changed query successfully which is effecting results of main category pages content. On loop.php modifying query with post tag make desired results. (In child theme)

But when it comes to top grid, it is hard-cord value of 5 passed there and if posts with tag are not present it displays nothing.

I found this piece of code which is calling Top grid :

<?php td_api_category_template::_helper_show_category_template() ?>
<?php td_api_category_top_posts_style::_helper_show_category_top_posts_style() ?>

And there is main function in File: /Newspaper/includes/wp_booster/td_wp_booster_functions.php

/* ----------------------------------------------------------------------------
 * modify the main query for category pages
 */
add_action('pre_get_posts', 'td_modify_main_query_for_category_page');
function td_modify_main_query_for_category_page($query) {

  

    //checking for category page and main query
    if(!is_admin() and is_category() and $query->is_main_query()) {

        //get the number of page where on
        $paged = get_query_var('paged');

        //get the filter_by

         URL($_GET) variable
        $filter_by = get_query_var('filter_by');
        
       <strong> $query_tag = filter_input( INPUT_GET, 'tag', FILTER_DEFAULT );
            
            if($query_tag)
            $query->set('tag',$query_tag); /*<strong>I tried modifying query but it does not effect top posts*/</strong>

        //get the limit of posts on the category page
        $limit = get_option('posts_per_page');

        // get the category object - with or without permalinks
        if (empty($query->query_vars['cat'])) {
            td_global::$current_category_obj = get_category_by_path(get_query_var('category_name'), false);  // when we have permalinks, we have to get the category object like this.
        } else {
            td_global::$current_category_obj = get_category($query->query_vars['cat']);
        }

        //offset is hardcoded because of big grid
        $offset = td_api_category_top_posts_style::_helper_get_posts_shown_in_the_loop();

        //echo $filter_by;
        switch ($filter_by) {
            case 'featured':
                //get the category object
                $query->set('category_name',  td_global::$current_category_obj->slug);
                $query->set('cat', get_cat_ID(TD_FEATURED_CAT)); //add the fetured cat
                break;

            case 'popular':
                $query->set('meta_key', td_page_views::$post_view_counter_key);
                $query->set('orderby', 'meta_value_num');
                $query->set('order', 'DESC');
                break;

            case 'popular7':
                $query->set('meta_key', td_page_views::$post_view_counter_7_day_total);
                $query->set('orderby', 'meta_value_num');
                $query->set('order', 'DESC');
                break;

            case 'review_high':
                $query->set('meta_key', td_review::$td_review_key);
                $query->set('orderby', 'meta_value_num');
                $query->set('order', 'DESC');
                break;

            case 'random_posts':
                $query->set('orderby', 'rand');
                break;
        }//end switch

	    // offset + custom pagination - if we have offset, WordPress overwrites the pagination and works with offset + limit
	    if(empty($query->is_feed)) {
		    if ( ! empty( $offset ) and $paged > 1 ) {
			    $query->set( 'offset', $offset + ( ( $paged - 1 ) * $limit ) );
		    } else {
			    $query->set( 'offset', $offset );
		    }
	    }
             
            
         
    }//end if main query
}

While using Grid style one:

includes/shortcodes/td_block_big_grid_1.php

POST_LIMIT is passed as 5.

So is there any way that my category posts get filter by tag for top grid as well. I tried modifying main function as mentioned above. Please see this comment in code above (I tried modifying query but it does not effect top posts)

Please suggest how that will be possible.

Screen shot attached for details of URL having query string:

Hello,

So I tried to apply the same pagination answer from a Newsmag thread to Newspaper in order to have the numbers removed and display only “NEXT”/”PREVIOUS”. (I realized the screenshots are actually from a Newspaper theme)

However it doesn’t work. I looked at both files in Newsmag and Newspaper (td_module_single_base.php and td_wp_booster_functions) and in both cases the code regarding pagination is exactly the same.

It works when I use this tutorial on Newsmag and have the filter removed via functions.php in the child theme but it doesn’t work for Newspaper. Somehow Newspaper is forcing numbered pagination somewhere else.

Any ideas on solving this?

Thanks!

Hi,

Can you help me?

Thanks in advance.

Hello to everyone.

I just installed child theme like 3 days ago.
i have take it from parent theme only these:
1)style.css
2)functions.php
3)comments.php
4)header-style1.php

My web site is: http://www.storypickers.com

I dont’t have any problem or something like that, but i was wondering do i need to take more files
from the parent theme?

For example if i want to modify any code or something to my web site, they tell my to put a code at header.php
But i don’t have a header.php. So, i need to take the header.php and put it at my child theme, or i need to put the code inside to the parent them to header.php???

Waiting for your reply wish to you king regards

I activated the child theme, but when I enter my customization in the file functions.php I get a fatal error php on the site …

here’s the code that I add after the basic template functions.php on child


// funzioni personalizzate
// Setup Admin Thumbnail Size
if ( function_exists( 'add_theme_support' ) ) {
add_image_size( 'admin-thumb', 100, 999999 ); // 100 pixels wide (and unlimited height)
}
// Thumbnails to Admin Post View
add_filter('manage_posts_columns', 'posts_columns', 5);
add_action('manage_posts_custom_column', 'posts_custom_columns', 5, 2);

// fine funzioni personalizzate


thank you 🙂

Hi
I want to use your child theme and have read your doc here
https://forum.tagdiv.com/the-child-theme-support-tutorial/

so basically I just use FTP to make a folder name “newspaper-child”, upload functions.php and style.css under your zip file/code/newspaper-child and then done?

do I need to activate it from anywhere at mydomain.com/wp-admin ?

Can i overwrite functions.php using child theme? Do i simply copy the function to the existing functions.php in the newspaper-child folder or do i have to use theme api?
