Hi
I'm using a script which I found on the internet which will search a pre-defined text file and if a keyword matches - it will display an EXTRACT of the text file entry which contains the keyword.
It works well - but I need the script to display the full entry(ies) in the text file (each entry is on a separate line) that match the keyword(s).
I've been on this for a week now - and I'm just a beginner with php.
Can anyone help me???
It seems that the code is stopping the full text entry from displaying because of an extract limiter.... (I think...)
I've removed the css from the code below as code was too big to display here...
