hello everyone i need help in may page. I need a textbox that only accepts alphabets. how it is done?:undecided thanks.
alphabets == alpha_simple_capital?? you mean without numbers, slashes, commas ? if its that you need to make a JS script that runs at the text change so that if the keyCode is not among the 'alphabet' values then its not added to the textbox or simply a php script which detect it as an error and show the error message
oh i see.. tnx manzzup.. :nice: i will just create a JS. hmm.. i wanna know how to use php script to detect numbers and special characters and show the error when these characters was inputed in my textbox..:nice:
for the php script, you'll be getting the input form POST or GET as usual and then run it through a func. just like the JS one something like; function isAllAlpha($str){ //your coding return true or false } if(isAllAlpha($_POST['txt'])) echo "OK"; else echo "Error";
php has isNumeric() and isNaN() functions you could use to check if its a number. Then create an array with all special characters and loop through it to see if the content contains them or use regex to perform a search for numbers and special characters. Its best if you did this on the client end though since it wont burn server resources doing it.
