Hi, I want to use LateX code for math courses, I'm using jetpack beautiful. When i edit in admin, it's working fine, but edit in front-end courses with ajax remove all backslash :(. Do you have a solution ?

Please try adding the latex shortcodes in text mode of wp-editor : http://prntscr.com/ch3vll

Hi alex, Alredy try, it's doesn't work :(. I write [latex]d = \frac{1} {2}gt^2,d \;\text{in meters}[/latex], and after saving, in database i have => d = frac{1} {2}gt^2,d ;text{in meters}. :(

I was not able to replicate the issue at my test site please refer : http://screencast-o-matic.com/watch/cDQIlajl2t Can you please try deactivating third party plugins and check again . If above does not helps then please share your site url and admin credentials to check the issue at your end .

Hi Alex, In your test, you obtain d = frac{1} {2}gt^2,d ;text{in meters} But you should have d = \frac{1}{2}gt^2,d \;\text{in meters}. In front-end, the ajax removes backslahes.   Result with backslahes =>  Result without backslahes =>  Best regards, MPR

I guess this is an issue related to the wordpress itself coz we do not make any changes while saving the contents .Can you please check this on wordpress default 2015 theme in from end editor just like  that of the bbpress ?

Hi Alex, It's the same on wordpress default 2015. But I noticed that i write 4 backslahes (\\\\) I get one \ . (only with ajax validation courses process) MPR

Ok I was able to replicate the issue on my test site . YEs the backslash was stripping in front end course creation . And also you observation is correct for putting four backslashes to make the shortcode to work. The problem is in front end editor post content is sent in the form of json data and it adds double slashes instead of one slash in it for which to handle we need to use the php stripslashes function to strip the slashes . Now we cannot remove this stripslashes coz if we do that ,then all the slashes will be saved that is added in the json data forcefully. So I would recommend to use the back end editor for the latex or use four slashes if using front end editor .
