Hello!

I want to enter data into database with something like this:

Code Download source

dbquery("insert into ".DB_MYTABLE."(unival,val2,val3)values('test','test','test')");


The column "unival" has a Unique-Key on it, which means i can't insert the same value twice.
Now if i do insert the same value a second time, i get this message:
"Duplicate entry 'test' for key 'unival'"

So i tried some things, but can't figure out how this works:
Code Download source

if(!dbquery(...)){
  echo "unival already exists";
}

Code Download source

try{
  dbquery(...);
}catch(Exception $e){
  if(stripos($e->getMessage(),"Duplicate")){
     echo "unival already exists";
  }
}


Both don't work. So how do i do it right?

Try this way
Code Download source
<?php
if (dbcount("(*)", DB_MYTABLE, "unival='test' AND val2='test' AND val3='test'") == 0) {
   dbquery("INSERT INTO ".DB_MYTABLE."(unival,val2,val3) VALUES ('test','test','test')");
} else {
   echo "unival already exist";
}
?>
