Solution mac_gyver Posted June 22, 2013 Solution Share Posted June 22, 2013 the values you are using in the form are Yes and No. those are not the same as the values in your comparisons, yes and no. the computer does exactly what your code says. the string 'Yes' is not equal to the string 'yes'. there are very few cases in programming where letter-case doesn't matter, and those would be specifically documented.

pietbez Posted June 22, 2013 Author Share Posted June 22, 2013 sorry for that. that was a stupid mistake. cant believe i didnt pick that up. sometimes when you stare at the code to long you start missing things. thanks for that.

Irate Posted June 23, 2013 Share Posted June 23, 2013 True and false boolean values are case-insensitive in PHP, for example. <?php $booltrue = TRUE; $boolfalse = FALSE; $citrue = true; $cifalse = false; $t = $booltrue === $citrue // $t now holds the value true $f = $boolfalse === $cifalse // $f is also true now ?> Quote Link to comment https://forums.phpfreaks.com/topic/279446-if-else-statement/#findComment-1437521 Share on other sites More sharing options...
