I need a regex to verify if the textarea has one of the following matches:
[img]https://example.com/image.jpg[/img]
[img=https://example.com/image.jpg]
This is what I've been trying so far, but it doesn't work, sadly...
/\[img(?=|\])(https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*))(?\])(?\[\/img\])/gi
Thank you.
You can use this- ^\[img(?:\].+\[\/img\]|=.+\])$
Note: If you want to verify the link string is a valid URL, replace both .+ with a URL regex matcher, you may find one here
^\[img - This part is common both strings, this will match the [img at the start of line(?:\].+\[\/img\]|=.+\])$ - This will match 2 alternatives, depending on the very first character
First alternative (first character is ]) - In this case \].+\[\/img\]| will be matched. This will match everything (.+) in between the opening and closing [img] tags before finally matching the closing tag itself.
Second alternative (first character is =) - In this case =.+\] will be matched. This grabs everything after img= and stops when ] is reached.
finally the regex matches the end of line.
