Hi,

I have a text field which is :

\<%= text\_field( “select”, “name” ,{:onchange =\>  
“this.form.submit();”} ) %\>

I want to search database using value entered by user, and when search  
results are displayed, I want to have text field retailn the value  
which was entered to have search results.

I did something like this,

\<% eventname = params[:select\_name]%\>  
\<%if eventname!=nil%\>  
\<% @select.name = eventname %\>  
\<% end %\>

Still, it does not contain that value which user entered.

Can anyone help please?

Thanks very much,  
Pat

Take a look at development.log (or if you’ve just done ruby script/  
server, the output will be in that window too). The log shows you the  
params hash for each request. You should be able to work it out from  
there.
