How to export multiple selected tables in PMA phpmyadmin (but not all tables)

Click on export, and choose “custom” export method.

Lets say you want to export first 20 tables only.

Open chrome or browser console [ctrl+shift+j], enter the following:


For next 20, use 20,50 as arguments in slice function used above.

Where are customizer settings stored in db for wordpress theme?

How to clone customizer settings in child theme from parent theme?

The customizer data is stored in table wp_options under option_name theme_mods_THEME-NAME

you can view all such settings via the following query:

SELECT * FROM `wp_options` WHERE `option_name` LIKE "theme_mods_%"

In some cases, you just want to use parent theme’s settings in newly added child theme. If that is your case too, use the following queries to utilize and close those settings for your child theme also.

update `wp_options` set `option_name`="theme_mods_YOURCHILDTHEME_backup" where `option_name`="theme_mods_YOURCHILDTHEME";
insert into `wp_options` (`option_name`,`option_value`,`autoload`) select "theme_mods_YOURCHILDTHEME",`option_value`,"yes" from `wp_options` where `option_name`="theme_mods_PARENTTHEME";

The following one is a bit risky one. If you understand what is going on here, go ahead.

delete from `wp_options` where `option_name`="theme_mods_YOURCHILDTHEME";
insert into `wp_options` (`option_name`,`option_value`,`autoload`) select "theme_mods_YOURCHILDTHEME",`option_value`,"yes" from `wp_options` where `option_name`="theme_mods_PARENTTHEME";

prevent sticky header jumping in css or js

jQuery(document).ready(function(){var header=jQuery("header .fusion-header");var headerHeight=0; var shouldWrite=1;
if(shouldWrite && headerHeight!==undefined){
jQuery("#headerjumpfixer").html(".fusion-header-wrapper.fusion-is-sticky{padding-top:"+headerHeight + "px}");
<style id="headerjumpfixer">.fusion-header-wrapper.fusion-is-sticky{padding-top:88px}</style>

Installing a testing instance for Magento CLI only


  • Magento repo access keys
  • Mysql Database, username and password
  • a domain name pointing to a server

if you dont have access key, get a pair here :

php -d memory_limit=-1 /bin/composer create-project --repository-url= magento/project-community-edition=2.2.11 ./

In the above command, you can change version/subversion of magento repo. You can also change the install directory

After the successful run of above command:

bin/magento setup:install \
--base-url= \
--db-host=localhost \
--db-name=testmage_x1 \
--db-user=testmage_x1 \
--db-password=WEux3dxxxxw \
--admin-firstname=xxx \
--admin-lastname=yyy \
[email protected] \
--admin-user=admin \
--admin-password=WwKhxxxxxxEK \
--language=en_US \
--currency=USD \
--timezone=America/Chicago \

YOu will see Magento Admin URI: /admin_10lf7y after successful run

Next is installing sample data: totally optional

php -d memory_limit=-1 bin/magento sampledata:deploy

OPtional: install or update composer version

composer self-update --2

Basic Authentication with Nginx with proxy port (react/node app etc)


Requirements: apache2-utils or httpd-tools

Use htpasswd utility and create a .htpasswd file, see reference

htpasswd -c  /etc/nginx/.htpasswd usernamethatyouwant
chmod 644 /etc/nginx/.htpasswd

After that, just add lines in nginx conf

location / {
	auth_basic "Backend Area";
    auth_basic_user_file /etc/nginx/.htpasswd; ## path to your passwd file
	## ...
	## xyz code
	proxy_pass; ## Proxy port for your app
	proxy_set_header Authorization ""; ## DONT FORGET THIS. reset the auth header

Restart nginx now or test first using “nginx -t”

Fixing broken “screen options” in wordpress site

SELECT * from wp_usermeta where `meta_key` like 'edit_%_per_page'

So probably you chose “Number of items per page” as 1000 or 200 and now the page doesnt load anymore because your database ran out of memory.

If that is the case, run the above query on phpmysql or any other way, edit the numbers and fixed!
