I am creating a web application where teachers can enter maths, physics and chemistry questions and notes. The problem that I am currently facing is how to enable copying equations from Microsoft Word and being able to paste into a textarea. Non-equation parts of text successfully copy over. Alternatively, is there is a way a teacher can upload a Word file and my application converts it to an image?
For directly typing into the textarea, I am using wiris editor. I am using PHP, MySQL and JavaScript.
The short answer is no. The best solution for you would be for teachers to export equations as images. It appears that Word 2010 + Save math equation as image has a solution for this (cumbersome as it is).
From this image, your page would have to accept image files for upload. You can prepare this by having your form include an enctype as follows:
