oobradersoo Posted January 22, 2014 Share Posted January 22, 2014 hello guys just a quick question i have made a html form with php embedded. here is php code: how could i change the code if 1 of the inputs is'nt numeric then it would echo a message saying "insert numeric values" at the minute it echos that if all numeric values are entered. elseif(is_numeric($_POST['number1']) && is_numeric($_POST['number2']) && is_numeric($_POST['number3']) && is_numeric($_POST['number4'])){ echo "please insert number"; Link to comment https://forums.phpfreaks.com/topic/285601-is_numeric-if-one-of-the-inputs-isnt-numeric-then-echo-message/ Share on other sites More sharing options...
ginerjm Posted January 23, 2014 Share Posted January 23, 2014 Uh...... try using OR instead of AND and then look for the negative of the tests ( ! )????

ginerjm Posted January 23, 2014 Share Posted January 23, 2014 just realized you had an 'elseif' there. In that case go back to && instead of || (as I suggested) but put a ! in front of a set of parens wrapping all your tests. elseif (!(test && test && test &&test)) { echo error } Link to comment https://forums.phpfreaks.com/topic/285601-is_numeric-if-one-of-the-inputs-isnt-numeric-then-echo-message/#findComment-1466235 Share on other sites More sharing options...

Mace Posted January 23, 2014 Share Posted January 23, 2014 ginerjm solution is this: elseif(!(is_numeric($_POST['number1']) && is_numeric($_POST['number2']) && is_numeric($_POST['number3']) && is_numeric($_POST['number4']))){ Link to comment https://forums.phpfreaks.com/topic/285601-is_numeric-if-one-of-the-inputs-isnt-numeric-then-echo-message/#findComment-1466261 Share on other sites More sharing options...
cyberRobot Posted January 23, 2014 Share Posted January 23, 2014 Side note: Are you okay with values like "4e1" and "3.1" being valid numbers? If not, you could use ctype_digit() instead of is_numeric(): http://www.php.net/manual/en/function.ctype-digit.php Link to comment https://forums.phpfreaks.com/topic/285601-is_numeric-if-one-of-the-inputs-isnt-numeric-then-echo-message/#findComment-1466275 Share on other sites More sharing options...
