How to install angularJS in windows/linux

Rate this post

HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop.

AngularJS is a toolset for building the framework most suited to your application development. It is fully extensible and works well with other libraries.

1) It may be possible to raise your memory limit, as in the thread that mbrsolution links to – add this to your wp-config.php file:
define(‘WP_MEMORY_LIMIT’, ’64M’);

2) You could ask your web hosting company to either raise the limit, or justify it. There’s really no justification for it though – as I say, they’re easily in the bottom 1% there.

3) More technical is to go through your plugins one-by-one to find out which is the one using up most memory. Just because UpdraftPlus tips it over the limit doesn’t indicate that it’s the one using most memory – it just means that when UD gets its turn to run, it uses more memory than what’s left of the 40Mb; but “what’s left” at that stage could be anything. You can try disabling all your other plugins, and looking at the UpdraftPlus page, in the “expert” section (down the bottom) – there, it has a counter of memory used. Re-enable your plugins one-by-one and see which one causes the biggest increase in usage. I’d not really recommend spending huge amounts of time on that, though – it’d be more efficient to pursue 1) and 2) and if they won’t raise it for you, switch to a new web hosting company.

Delete all posts from wordpress by phpmyadmin

The original is ‘post’ in the sense that it is the first db record created for that post, and always has the same ID. As you make revisions, WP continually updates that original record and keeps it current. It also periodically makes copies of the post record, marking them ‘revision’ and giving them unique IDs.

The only relationship between posts and revisions from a db standpoint is that the revisions store the ID of the original (and current) post record in the ‘post_parent’ field. So, if you wanted to see all revisions of post ID 22, sorted by date, you would use a query like this:

SELECT * FROM wp_posts WHERE post_type=’revision’ and post_parent=22 ORDER BY post_date DESC;

The revisions are only there as a backup. The most current version of a post is always stored in the original record. So it does no harm to purge the database of revisions, using a query like this:

DELETE FROM wp_posts WHERE post_type=’revision’;

Going back to your first question, you can retrieve all the info for the current posts simply by querying on post_type=’post’, like this:

SELECT * FROM wp_posts WHERE post_type=’post’ and post_status=’publish’ ORDER BY post_date DESC;
