Question

Auto Complete / Google Suggest for a text box /drop down

Asked by: majdolyan

Hi,
I have a form which has many fields. In one of them I want to have a field for a drop down list/textbox where user can use auto complete ajax library to suggest things from another file.

The other file has different columns and auto complete should be able to read from any column.

The file structure is like this:

Airport ID, Name, City, Country
SFO, San Francisco Airport, San Francisco, USA

So if a user insert SFO or USA or Airport name or city, this line has to appear in the drop down list.

Please suggest a script that I can use to be embedded in my website.

Here are a few autocomplete scripts http://www.ajaxdaddy.com/. I didn't check it out, but since they all has to use AJAX and call i.e. some php script to fetch the data for autocomplete box it depends only on how you compose the sql statement in it. i.e. "SELECT Airport_ID, Name, City, Country FROM table WHERE Airport_ID LIKE '{$prefix}%' OR Name LIKE '{$prefix}%' OR City LIKE '{$prefix}%' OR Country LIKE '{$prefix}%'". I think that LIKE operator doesn't use index (probably uses FULLTEXT index (only MyISAM engine)) so statement like this will be really slow on big tables. After fetching the result from database you should check every row and choose only columns matching $prefix.
