Re: [PHP-DB] full text search and how to underline keyword in results
Hi Andy,
In answer to part two - here's a snippet of code I use to highlight relevant
words in red - hope it helps to put you on the right track.
for ($i=0; $i count($keywords); $i++) {
$blurb = eregi_replace( .$keywords[$i]. , font
color=\#FF\.$keywords[$i]./font , $blurb);
}
where $keywords is an array containing all the words searched for and $blurb
is the snippet that is returned with the search results At this stage in the
flow, I've already retrieved relevant records - this is in fact the last
step before I format and display the results..
Hope this helps

Subject: [PHP-DB] full text search and how to underline keyword in results
Hi there,
I am trying to write a php script to perform a full text search on a mysql
db. I do a match against... and it digs out some results out of the db.
There are 2 problems:
1. How can I restrict the results to e.g. 100 characters, but to make sure
the keyword is within this 100 characters?
2. Is it possible with php to underline the keyword inside the search
results. This might be more tricky.
Thank you for any help on that,
Andy

Hello Stuart,
great, thats a first success and works fast.
There are just 2 things which fail on this function:
1. Problems with full stops. A word with a full stop will be ignored (e.g
singapore. will not be found if you search for singapore)
2. If you search for singapore and there is a hit Singapore (notice the
capital!) will be replaced with singapore in the text.
I tryed to fix that, but I fear that my php experiance lacks on this stage
:-(
Maybe someone else or you do have a idea for a fix?
Cheers Andy

Re: [PHP-DB] want to compare text input with blob field
Funny, I just had the same problem! I converted the blob column to a text column and then the problem went away. This page may be of use from the MySQL manual: http://www.mysql.com/doc/en/Case_Sensitivity_Operators.html But I couldn't get their solution to work, so I changed the format of the column to TEXT and it works fine.

Re: [PHP-DB] keeping form field data when reloading a form
Are you setting the variables in the form? Something like this - note the value field in the username field: form method=post action=index.php name=loginuser table summary=layout table to hold login data width=300 align=center cellpadding=1 cellspacing=0 border=0 bgcolor=#ff tr td align=leftp class=smallbUsername:/b/p/td td align=leftinput type=text name=username value=?php echo $username;? maxlength=50 size=15 style=width: 120px; font-size: 12px/td /tr tr td align=left p class=smallbPassword:/b/p/td td align=leftinput type=password name=password maxlength=50 size=15 style=width: 120px; font-size: 12px /tr tr td align=leftpnbsp; /p/td td align=leftpinput type=submit value=login name=login style=width: 50px; heigth: 18px; font-size: 12px/p/td /tr /table /form This way, depending on how youare refreshing the login form, if the $username variable passed your validation tests it should be set automatically into the form.
