Orate! Posted October 9, 2005 Share Posted October 9, 2005 Hello there guys, i have a little problem in mysql/php i'm pretty sure someone will be able tu help me ... (I'm a n00b in programming matters at this point, so sorry if its a stupid question).. I have this form (fig a.) working in a web browser, but when the client leaves the field in blank Mysql stores a "0" (zero) on it, but a need to be (null,1,2,3,4,5,6,7,8,9,10) ONLY, not zero not 15, only the list on (), and obviously is mysql completing the field with zeros, rather than leaving it blank, is there a way to tell that blank is ok in the field? (fig a.)( <select name="xtag01"> <option></option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> ) Thanks guys (sorry for my rusty english) bye and thanks in advance.

ryanlwh Posted October 9, 2005 Share Posted October 9, 2005 the problem lies in your form <option VALUE="1">1</option> You didn't give the option a value, so it passes a null string. And by the way, int can never be null... if you need null values, use varchar.

ryanlwh Posted October 11, 2005 Share Posted October 11, 2005 well i think so. never tried that but you can try. but why doesn't 0 work for you? why do you need it to be null for an int anyway?
