parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I'm a student building a PHP project trying to get product names and their respective prices (from a mysql database table) to display one after the other in a dropdown list. The customer will select one of the items, and check one or both of the check boxes before pressing the place order button, at which point their item selection, order total, and chosen gift option will display in table form on a separate page. I've gotten all of the correct info to display in the dropdown list, as well as getting the check boxes to function properly, but all of the product data is on one line, and end to end. I don't get any errors at all when I load the page. I tried it another way in which I defined multiple instances of the echo statement, which formatted correctly, but only listed the first item in the database table repeatedly. These two different approaches are displayed below:

I've isolated my issue but haven't been able to fix it. I'm hoping the brilliant minds of stack overflow can assist!
Problem: The sorting function stops working when the injected tables are present. When I remove the injections, the sorting functions work perfectly. Is there a way for me to isolate the script src so it will work only for the injected charts? Trying to reference them before the highcharts doesn't work.
My page: http://www.wcsddata.net/wearewcsd
At the beginning of my page I reference the following scripts, so, my highcharts will work at the bottom of the page in the tabs:
...ANSWER
Answered 2020-Apr-20 at 08:34I found that it is a general issue between integration of the everviz charts and the Highcharts charts. The issue occurs because everviz includes all Highcharts modules and doing an update on the main chart makes that this chart "want to get access" to these modules, but assigned arguments are wrong.
Adding missing modules (highcharts-more and accessibility in this case) fixes the issue.

I have PHP (Laravel 5.7) application connected to a cluster of DBs powered by Galera cluster. I am running cron job every night to clear thousands of thousands log data from DB tables. I run Delete
statement of the MySQL to delete the rows in the table based on the time stamp range.
My Delete Operations looks like
...ANSWER
Answered 2018-Dec-19 at 18:44You are deleting half the table every night? Consider deleting an hour's worth every hour.
Do you have INDEX(created_at)
? That would help the hourly purge, though perhaps not the daily purge.
This task is an excellent one for PARTITIONing
.
These, and more techniques, are discussed here.
QUESTION
I have a shapfile of school districts in Texas and am trying to use ggplot2
to highlight 10 in particular. I've tinkered with it and gotten everything set up, but when I spot checked it I realized the 10 districts highlighted are not in fact the ones I want to be highlighted.
The shapefile can be downloaded from this link to the Texas Education Agency Public Open Data Site.
...ANSWER
Answered 2018-Mar-21 at 23:02Alternative 1
With the fortify
function add the argument region
specifying "NAME2", the column id will include your district names then. Then create your dummy fill variable based on that column.
I am not familiar with Texas districts, but I assume the result is right.
