Bericht weergeven indien geen resultaat
Ik heb hier een postvak-in script. Maar als er nu geen berichten in staan, dan geeft die niks weer. Ik zou graag hiervan een melding willen plaatsen indien geen berichten.
Dit is het script:

Bedankt!
Dus maak een query die daar de berichten ophaalt.
Overigens mis ik ook foutafhandeling op je query.
if(mysql_num_rows($result)>1)
moet je veranderen in
if(mysql_num_rows($result)>=1)
Als je dat niet doet en er is slechts 1 resultaat, dan word deze niet meegenomen.
