I have a problem, namely I want to display hashtags from such table "posts":
| id | author | hashtags |
|:------------|-------------:|
| 1 | aaaa | #aaa, #bbbb | etc...
| 2 | bbbb | #ccc, #addd |
| 3 | cccc | #aee, #ffff |
The problem is that I would like to get something like this (only those records):
When I write a: #aaa, #addd, #aee
When I write b: #bbbb
etc...
How do I get the effect that only those hashtags that start with a letter (even in the same field) appear to me? I was thinking about regular expressions. Thanks in advance for any help.
