  1. I' stuck with writing function for searching replaced numbers and would really appreciate if someone can tell me what I'm doing wrong. My table structure looks like: CREATE TABLE servis.zamjene_brojeva ( id INT(11) NOT NULL AUTO_INCREMENT, vrijeme TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, pocetni_broj VARCHAR(55) DEFAULT NULL, zamjenski_broj VARCHAR(55) DEFAULT NULL, glavni_broj VARCHAR(55) DEFAULT NULL, postoji_zamjena INT(1) DEFAULT NULL, PRIMARY KEY (id) ) My function looks like this: //funkcija za traženje zamjene brojeva function zamjena_broja($kataloski_broj){ //Traženje zamjenskog broja $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE glavni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $row = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row["zamjenski_broj"]; $broj_zamjena = mysql_num_rows($rezultat_zamjena); return $kataloski_broj; //Traženje druge zamjene broja if ($broj_zamjena <> 0) { $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE pocetni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $broj_zamjena2 = mysql_num_rows($rezultat_zamjena); $row2 = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row2["zamjenski_broj"]; return $kataloski_broj; //Traženje treće zamjene if ($broj_zamjena2 <> 0) { $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE pocetni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $broj_zamjena3 = mysql_num_rows($rezultat_zamjena); $row3 = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row3["zamjenski_broj"]; return $kataloski_broj; } } } In pocetni_broj is old number and in glavni_broj is new number. But it can happen that number in glavni_broj is old and I need to search in pocetni_broj to see if there is even newer number and it can happen 5 or 6 times like that. I need to find all the numbers that are connected, but I'm not getting that. What am I doing wrong?
