MAMP MYPHPADMIN Delete wordpress trash

Delete Trash from WordPress

Delete WordPress Trash from SQLAs I was testing on mij localhost (using MAMP) I run into trouble while permanently deleting several hundred products from my Trash.

Instead of using WordPress interface I decided to user MyPhPAdmin to do this. Whereas WordPress gave and timeout when only selecting a few products, via SQL the job was doen in less than 3 seconds.

Here’s the Code snippet:

DELETE wp_posts,wp_term_relationships,wp_postmeta,wp_term_taxonomy
FROM wp_posts 
LEFT JOIN wp_term_relationships ON ( wp_posts.ID = wp_term_relationships.object_id )
LEFT JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
LEFT JOIN wp_term_taxonomy ON ( wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id )
WHERE wp_posts.post_status='trash';

How make row in Parse Unique using Parse CloudCode

In the Parse app database there is no option to make a key (object) unique. Usually you can chat using af find before adding a row but when you use .saveinbackground()  you cannot be sure.

Best solution is to add a beforeSave trigger on Parse Server using cloud code. I’m not a cloud code specialist so it took me quite a while to figure it out but using the code below you should be able to do this pretty quick.

This needs no modification of you app.

Add this (and adust to your needs) to you main.js and upload to Parse Server.

myObjectClass is the ‘table name’ in Parse.
myKey is the ‘field’ you want to make unique within your table (object)

Parse.Cloud.beforeSave("myObjectClass", function(request, response) {
    var myObject = request.object;
	if (myObject.isNew()){  // only check new records, else its a update
		var query = new Parse.Query("myObjectClass");
			success:function(number){ //record found, don't save
				//sResult = number;
				if (number > 0 ){
					response.error("Record already exists");
				} else {
			error:function(error){ // no record found -> save
    } else {

WordPress Database size in phpMyAdmin

How to show WordPress database size in pypmyadminI got an email from my hosting provider that I was exceeding my wordpress database space of 1000MB, which I thought was very strange. Had 2 dabases in which I each imported content of about 50MB (gzip format). I could not find the actual database size so I did some digging around and found the SQL code below which does the trick:

SELECT table_schema "Data Base Name",
sum( data_length + index_length ) / 1024 / 1024 "Data Base Size in MB"
