You can use /^[A-Za-z0-9]{6}-\d{2}-[A-Za-z0-9]-\d{4}$/ Or shorter with the case insensitive flag: /^[A-Z0-9]{6}-\d{2}-[A-Z0-9]-\d{4}$/i solved Need JS Pattern Validation
For making field MANDATORY: Use RequiredFieldValidator: <asp:TextBox ID=”txtName” runat=”server”></asp:TextBox> <asp:RequiredFieldValidator ID=”RequiredFieldValidator1″ runat=”server” ControlToValidate=”txtName” ErrorMessage=”Input Country!” EnableClientScript=”true” SetFocusOnError=”true” Text=”*”> </asp:RequiredFieldValidator> For Validating Range of Number in TextBox use RangeValidator: <asp:TextBox ID=”TextBox1″ runat=”server”></asp:TextBox> <asp:RangeValidator ID=”RangeValidator1″ runat=”server” ControlToValidate=”TextBox1″ MaximumValue=”200″ MinimumValue=”100″ Type=”Integer” ErrorMessage=”Please input between 100 to 200.”> </asp:RangeValidator> Read more about Validations Here Hope this helps you! 2 … Read more
I recommend you read a JavaScript tutorial. Try here. To answer your question, this will probably work. If you’re wondering why you’re getting downvoted – asking people to write your code for you is generally considered bad form, so try not to do this in future. 🙂 function Validateform(e) { if (document.getElementsByName(‘receiver’)[0].value.substring(0, 2) !== “92”) … Read more
You could write a custom validator function: For example(assumption, you have a followed_users method which returns all the users that the current user is following, and a follow method, taking a user id and “following this user.): class User < ActiveRecord::Base has_many :users, inverse_of :user, as: followed_users validates :verify_no_circular_followers def followed followed_users end def follow(user_id) … Read more
Your attempt is almost complete: Try this: /([-\d]{2,})_([a-zA-Z\d]+)([_-][a-zA-Z\d]+)*\.gif/ I added this: ([_-][a-zA-Z\d]+)* which matches an _ or – followed by a tag zero ore more times. And \.gif which matches the trailing .gif. 0 solved regex for specific filename [closed]
jQuery code will not work without the library being referenced on your page (usually in the <head> tags). Also, there are some other libraries that build on top of the jQuery library, like Twitter’s excellent bootstrap library, or jQueryUI. In those cases, you need both the jQuery library and the additional library — as shown … Read more
You can solve this by reading a string first, and then extracting any number: #include <stdio.h> int main(void) { int length = 0; char input[100]; while(length <= 0) { printf(“Enter length: “); fflush(stdout); if(fgets(input, sizeof input, stdin) != NULL) { if(sscanf(input, “%d”, &length) != 1) { length = 0; } } } printf(“length = %d\n”, … Read more
The following Regex should ensure that the name matches Google’s name guidelines: [-.’_-[:alnum:]]{6,20} 1 solved Does regexp to validate Youtube channel name and link to channel exists?
Here is a simple implementation – function validateUserName($uname){ $illegalCharacters = array(‘!’,’@’,’#’); // first check the length $length = strlen($uname); if ($length < 5 && $length > 10){ return false; }else{ // now check for illegal characters foreach($illegalCharacters AS $char){ if (strpos($uname,$char) != -1){ return false; } } } return true; } $userName = “user1905577”; if … Read more
Simply try this. (dd/mm/YYYY) Eg: 06/12/2014 if (preg_match(‘\d{1,2}/\d{1,2}/\d{4}’, $input)) { return true; // it matched, return true } else { return false; } 4 solved Regular Expression and Logic for Date Validation [closed]
Resulting from the descussion, you need one regular expression for each check to perform. At least 8 characters: ^.{8,}$ No whitespace character: ^\S*$ Both combined: ^\S{8,}$ Explanation: ^ Start of the string $ End of the string . Any character (inclusive whitespace) \S Any characters that is not whitespace {8,} previous expression 8 or more … Read more
Nothing Happens when you click submit because in your js you are calling this $(“.comment_form, .contact_form”).submit(function(event) and you have used event.preventDefault(); , therefore the form does not show default behavior. Check the console there is an error in you js. It says TypeError: $(…).block is not a function. you need to fix these errors first. … Read more
I found the solution. I got back to validate within appmodel which is more consistent. Cake wants the custom validation rules to be in the certain class where the rule is called. So, when you call a custom rule in class post, the custom function has to be written down in class post, otherwise cake … Read more
You have the following in your code: $name = $_POST[‘$name’]; $email = $_POST[‘$email’]; $dob = $_POST[‘$dob’]; You’re basically trying to access undefined indexes. Remove the extra $ from the key names: $name = $_POST[‘name’]; $email = $_POST[’email’]; $dob = $_POST[‘dob’]; Then, further below, you have some conditions like this: if(condition == true) { continue; } … Read more
