Problem with detecting an empty field

Discussion in 'PHP' started by mahmood, Sep 4, 2005.

    I am trying to detect an empty filed in mysql but seems that I am doint something wrong:
    SEMrush
    I tried both these codes:
    
    if ($myVariable != "")
    
    PHP:
    and
    
    if (isset($myVariable))
    
    PHP:
    But even when the field is empty they return true.

    What am I doing wrong?

    Have you echoed the var to see what is in it? Do you know what the variable is being type cast as by php?

    I'd try those two debugging ideas.

    Odds are the variable is a space. Try using this it might work.

    You might want to add both isset and empty.

    Good Luck.

    Thanks for replies

    Apparently the problem was with the logic. I would get the correct result but I expected vice versa.
