hi,

i'm making a website for a company, with backoffice. when i want to add a new employee, i must specify the monthly fee and i created two inputs, one for the dollar part and the other for the cents parts. i wanted to concatenate the two parts with a dot in the middle and then cast to float. but when i insert the employee, the salary stays on 99.99

what can i do?

``````\$euros = \$_POST['euros'];
\$cents = \$_POST['cents'];
if(is_numeric(\$euros) && is_numeric(\$cents)) { \$salary = \$euros + (\$cents / 100); }
else die('non-numeric inputs');``````

oneline code

``isnumeric(\$_POST['euros']) && isnumeric(\$_POST['cents']) ? \$salary=\$_POST['euros']+(\$_POST['cents']/100):die('non-numeric inputs');``

salaryfl;oat appears unneccessary

is_int() better AB? is_numeric() will accept float (and hex?) as input.
Can just imagine some noob entering .89 for 89c as opposed to just 89

Provide some code.

``````\$euros = \$_POST['euros'];
\$cents = \$_POST['cents'];

\$salary = \$euros.".".\$cents;
\$salaryFloat = (float) \$salary;``````
``````\$euros = \$_POST['euros'];
\$cents = \$_POST['cents'];
if(is_numeric(\$euros) && is_numeric(\$cents)) { \$salary = \$euros + (\$cents / 100); }
else die('non-numeric inputs');``````

oneline code

``isnumeric(\$_POST['euros']) && isnumeric(\$_POST['cents']) ? \$salary=\$_POST['euros']+(\$_POST['cents']/100):die('non-numeric inputs');``

commented: Thanks bloke +13

and the isnumeric() in the last one-liner should have been is_numeric(), is_int() is better
