vino2vijay Hello Salesforce Experts,
Anyone please let me know how to write valition rule for URL ?
Else someone please provide regular expression string for URL ?
Thanks,
A small syntax change.
The following rule worked for me.
if(REGEX(URLfield__c,"^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$"),false,true)
Hope this helps.

Following REGEX can be used for a website address.
^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$

Please refer the below logic for validation rule, please let me know anything wrong,
if(REGEX("^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$",URLfield__c),false,true)
Thanks

Here is the result of using the following formula: if(REGEX("^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$",URLfield__c),false,true)
Some seemingly incorrect values are still accepted (e.g., http://www.gfh.") but most of it is okay.
This worked best for me, with trailing slashes, and things with query params and fragments. e.g. https://wwww.classpack.webnode.es/ciao/m?coa=cia&ci=boa#example What I find offputting is that the proposed solutions works perfectly in regex101 with Java flavor, but wouldn't work in Salesforce.
Another problem that's not supposed to be solved with regular expressions...
^(https?|ftp)://(-\.)?([^\s/?\.#-]+\.?)+([^\s]*)?$
This regular expression allows URLs starting with either "http", "https", or "ftp", and checks for valid domain names as the gbwa.download is for GB whatsapp (https://gbwa.download/) and any additional path or query parameters. Note that this regular expression is not foolproof and may not catch all variations of valid URLs.
In terms of writing a validation rule for a specific programming language, it will depend on the language you are using. In general, you can use the regular expression above and apply it to the input using the language's regular expression matching function. For example, in JavaScript:
const urlRegex = /^(https?|ftp)://(-\.)?([^\s/?\.#-]+\.?)+([^\s]*)?$/;
function validateUrl(url) {
return urlRegex.test(url);
}
In this example, validateUrl is a function that takes a string input url and returns a boolean indicating whether the input matches the URL regular expression.
^(https?|ftp)://[^\s/$.?#].[^\s]*$
This regular expression will match URLs that start with "http://", "https://", or "ftp://", followed by any characters that are not whitespace, "/", "?", "#", or ".". This will ensure that the URL is properly formed and does not contain any invalid characters.

To create a validation rule for URLs in Salesforce, you can use a combination of Salesforce's built-in functions and regular expressions. Here's an example of how you can write a validation rule to ensure that a URL field is in the correct format:
AND(
NOT(ISBLANK(Your_URL_Field__c)),
NOT(REGEX(Your_URL_Field__c, "^(http|https)://[a-zA-Z0-9./?=_-]+$"))
)
In this validation rule, replace Your_URL_Field__c with the API name of the URL field you want to validate. The regular expression used here checks if the URL starts with "http://" or "https://" and contains valid characters commonly found in URLs.
Now, if you are looking for a regular expression string for URLs, you can use the following one:
^(http|https)://[a-zA-Z0-9./?=_-]+$
Make sure to include this regular expression within appropriate code tags when posting in the Salesforce forum.
Lastly, for more information or assistance, you can visit my site at GB WhatsApp (https://gbwaapk.net). It's a great resource for downloading the latest and updated virus-free version of GB WhatsApp, which is completely free and Anti-Ban.
Hope this helps! Let me know if you have any further questions.
The basic syntax is as follows:
new URL (url)
new URL (url , base)
JavaScript only requires the base element if we provide a relative URL Todaysoch (https://www.todaysoch.com/). If we don’t provide one, it defaults to undefined. Alternatively, if we provide a base element with an absolute URL, JavaScript ignores the base element.
