maxWait
(integer value) The maximum time, in milliseconds, that a connection pool waits (when no connection is available) to return a connection before throwing an exception. Default is 30000 (30 seconds)

And then we start writing the code that verifies the form.
First we need to know that the form needs to be validated
$ (function () {
$ (' #commentForm '). Validate ();
Then start writing the validation rules, notice that the selection element is selected based on the name attribute of each tag, and the basic syntax is as follows
$ (' #commentForm '). Validate ({

Basic validation Examples
Copy Code code as follows:
$validator = Validator::make (
Array (' name ' => ' Dayle '),
Array (' name ' => ' Required|min:5 ')
);
The first parameter passed to the Make function is the data to be validated, and the second parameter is the validation rule that needs to be applied to the data.
Multiple validation rules can be separated by the "|" character, or as a separate element of the array
First, data validation
