Hi. I have a problem and don´t know hot to solve it. I guess is a very basic thing but after fighting with it a whole week, I decide to ask here...

The thing is the following:

I have a database that I read perfectly, but, in that database, I have a field that can be with content or "came" empty.

I want to make this ...

If that field came empty, don´t do nothing, else (with content) do the other thing... like this;

if ( isset ( myfield ))
{
// DO THE CONDITION in myfield
} else
{
// DONT DO NOTHING
}

Is this correct??

How can I check thefield empty or not and do things depending on this condition??

Please, help.

Thanks.

Regards

if($myfield != ""){

//there is content, so do something with it

}else{

//There is no content

}
