i believe you, but this regex it's the one which filter_var() is using and it's for php. have a look here: http://fightingforalostcause.net/misc/2006/compare-email-regex.php thank you.

AyKay47, i tried now your regex and it's working. i also tried to replace your regex with this one /^(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){255,})(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){65,}@)(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22))(?:\.(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22)))*@(??:(?!.*[^.]{64,})(??:(?:xn--)?[a-z0-9]+(?:-[a-z0-9]+)*\.){1,126}){1,}(??:[a-z][a-z0-9]*)|(??:xn--)[a-z0-9]+))(?:-[a-z0-9]+)*)|(?:\[(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(??!(?:.*[a-f0-9][:\]]){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}|(??!(?:.*[a-f0-9]{5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}?)))?(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))\]))$/ and it's not working. i don't understand how it's working in jqery variable and in php not. to be clear, this it's working function validateEmail($email){ $pattern = "~\b[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}\b~i"; return preg_match($pattern,$email) } and this one not function validateEmail($email){ $pattern = "/^(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){255,})(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){65,}@)(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22))(?:\.(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22)))*@(??:(?!.*[^.]{64,})(??:(?:xn--)?[a-z0-9]+(?:-[a-z0-9]+)*\.){1,126}){1,}(??:[a-z][a-z0-9]*)|(??:xn--)[a-z0-9]+))(?:-[a-z0-9]+)*)|(?:\[(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(??!(?:.*[a-f0-9][:\]]){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}|(??!(?:.*[a-f0-9]{5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}?)))?(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))\]))$/"; return preg_match($pattern,$email) }

i tried now again and something it's working. if i put the email johnsmith@example.com it's working, but when i put john.smith@example.com it's not working anymore. i don't understand. i just discovered that even if i use return preg_match("/^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/", $email); the problem it's the same. :wtf: thank you!

i tried preg_match instead of ereg and it's not working. i am beginner in php, but i will learn it in the future. for now, i just want to make this working for my contact form. do you have any idea how to fix it ? i cannot use filter_var because this validators are in another file. i think that i need a good regex which checks the email. thank you very much.

hello. in my contact form i have 2 validators, one in jquery and one in php. the problem is next. this is the jquery where checks the email and it works perfectly ( i know that this regex is from php ). function validateEmail() { var filter = /^(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){255,})(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){65,}@)(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22))(?:\.(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22)))*@(??:(?!.*[^.]{64,})(??:(?:xn--)?[a-z0-9]+(?:-[a-z0-9]+)*\.){1,126}){1,}(??:[a-z][a-z0-9]*)|(??:xn--)[a-z0-9]+))(?:-[a-z0-9]+)*)|(?:\[(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(??!(?:.*[a-f0-9][:\]]){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}|(??!(?:.*[a-f0-9]{5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}?)))?(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))\]))$/; if(filter.test(email.val())) when i'm trying to put it in php, it doesn't work anymore. function validateEmail($email){ return ereg("^(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){255,})(?!(??:\x22?\x5C[\x00-\x7E]\x22?)|(?:\x22?[^\x5C\x22]\x22?)){65,}@)(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22))(?:\.(??:[\x21\x23-\x27\x2A\x2B\x2D\x2F-\x39\x3D\x3F\x5E-\x7E]+)|(?:\x22(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]|(?:\x5C[\x00-\x7F]))*\x22)))*@(??:(?!.*[^.]{64,})(??:(?:xn--)?[a-z0-9]+(?:-[a-z0-9]+)*\.){1,126}){1,}(??:[a-z][a-z0-9]*)|(??:xn--)[a-z0-9]+))(?:-[a-z0-9]+)*)|(?:\[(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(??!(?:.*[a-f0-9][:\]]){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(??:IPv6:(??:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}|(??!(?:.*[a-f0-9]{5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?:?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}?)))?(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(??:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))\]))$", $email); } if i put the next code instead of the one from up, it works. function validateEmail($email){ return ereg("^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$", $email); } does anyone have any idea ? thank you.

ok, now i have another question about the mail validation. mine looks like this: var filter = /^[a-z0-9]+[a-z0-9_.-]*[a-z0-9]+@[a-z0-9]+[a-z0-9.-]*[a-z0-9]+.[a-z]{2,6}$/; - the question is: what do you think ? add something ? do you have a better one ? thanks!

thank you for the hint with "?" - i converted it for my needs: var filter = /^([A-Z]{1,1})([a-z]{2,20})(\s[A-Z]{1,1}[a-z]{2,20})?$/; thank you again!

thank you for the answers, a little too complicated for me, but i understood the most of it. i use 2 regex because the user can enter only one name like "Green" or 2 names like "Green Trancer". now i understand better what is happening in that regex and i remade it for my form: var b = $("#name").val(); var filter = /^[A-Z]+[a-z]+$/; var filter2 = /^[A-Z]+[a-z]+\s[A-Z]+[a-z]+$/; //if it's valid email if((filter.test(b) || filter2.test(b)) && b.length > 2) thank you very much for the answers. if you want to add something, feel free to do it. thanks, again!

hello. i want to know what is *$ or +$ because i see it in many contact forms. also, what is the difference between these: /^[A-Z]+[a-z]*$/ /^[A-Z]+[a-z]+$/ /^[A-Z]+[a-z]$/ /^[A-Z]+[a-z]/ also, which is the shortest and efficient method of checking somebodys name to be exactly "Name Surname" - "Green Trancer" ? in my form, i use var filter = /^[A-Z]+[a-z]*$/; var filter2 = /^[A-Z]+[a-z]+\s+[A-Z]+[a-z]+$/; and then i check the name to be like filter or filter2. how can i check that between the words to be exactly one space character ? thank you very much.
