Ceva gen Topics Anywhere

[Birkoff]

Salutare

Vreau sa fac un script gen Topics Anywhere dar care sa nu imi returneze un cod java ci direct ultimele 10 mesaje scrise (indiferent de forum). Am reusit sa fac ceva asemanator si a mers o perioada pana am inceput sa sterg unele mesaje din forum si atunci script-ul s-a dat peste cap. Cred ca nu am inteles eu bine logica organizarii bazei de date...

Ma intereseaza daca stie cineva care sunt campurile din bd care ar trebui sa le citesc pentru a afisa ultimele 10 mesaje scrise (indiferent de forum)
Ceva ceva am facut eu, dar daca sterg un mesaj din forum, nu mai corespunde id-ul sau nu stiu ca nu mai merge scriptul pe care l-am facut, imi afiseaza ultimele 10 mesaje dar cu alte link-uri...

Ideea e ca scriptul vreau sa il folosesc pe serverul as.ro unde nu functioneaza Topics Anywhere...

Deci ma poate ajuta cineva sa imi zica care sunt campurile din bd care pastreaza ultimele 10 mesaje scrise?

Multumesc BuGsY 2 lucruri mai vreau

1. Nu inteleg ce face linia
$path = dirname(__FILE__);

mai exact __FILE__ ca instructiunea dirname stiu ce face...

2. Mi-ar mai trebui si mesajul propriu-zis, nu doar titlul subiectului si linkul, eu facusem sa imi afiseze si mesajul (de fapt x caractere din mesaj), poate imi dai o idee ce mai trebuie sa adaug la interogarea bazei de date... oricum o sa mai studiez codul si poate imi dau singur seama da poate o sa fie mai rapid daca sti tu...
