ANSWER
Answered 2021-Jun-08 at 17:57The post meta hasn't been registered on the curriculum-vitae
post type, so WordPress isn't able to update it. WordPress is trying to update it because the PluginDocumentSettingPanel
is still being rendered on the curriculum-vitae
post type.

QUESTION
I am writing the following script to be executed on SQL Server. I need to ensure that the correct foreign key records are mapped to the parent table. If you see below I am hardcoding the foreign key and assuming that sequentially it will execute and will be fine. I have around 100 plus records to be inserted. I need to know there is way to check the correct parent id before inserting the detail records.
Main table
...ANSWER
Answered 2021-May-28 at 15:45- This could be done in postgres using CTE but unfortunately sql server doesn't support this.
- Apart from this what you can do is run this whole thing as a single transaction and that too only after performing a check that the last id in
OnScreenText
is exactly 1 less than the first value ofOnScreenTextId
inOnScreenTextTranslation
table's data. - Summary
- Make sure the child and parent record are in expected sequence
- Start a transaction
- Fetch current last value (basically max/latest id) of Parent table's id column
- if (value from 3 == (value of parentId from 1st record of child insert statement) -1 )
- execute insert
- commit
- else rollback

I created the 2 html files in another spreadsheet and tested them OK. Then I copy&pasted the samples in my much bigger spreadsheet and it doesn't work. Well, it works when i debug each 'show' functions but not in the execution of the spreadsheet.

I have several forms "Login, Registration, Create a product..." For these forms, I was handling errors with useState for the front end and for the back end with express-validator.
Everything worked perfectly, I received error messages as expected.

Here is my code that NORMALLY shows me the errors : (For example, this is my login page where I only get one error message)

Answered 2021-May-30 at 08:47You've missed one thing, to return the error from axios response interceptor when error.response.status
is not 403
