isDate()

hi Guys,

 

I have html <input type = 'text'...> field where user can enter date. 

 

Is there a way to make sure a valid date has been entered and the format is 'dd'/mm/yyyy'.

 

Many thanks

You could use regex:

 

if (preg_match('/^(0[1-9]|[1-2][0-9]|3[0-1])\/(0[1-9]|1[0-2])\/[0-9]{4}$/', $date))
{
    echo 'valid date: ' . $date;
}

There are a variety of ways to do this, you can use javascript to make sure an alert is shown that the date is not valid or you can use php/ajax to show an error once the form is submitted that the data is not valid.  What are you looking to do with this?

Given the forum this is posted in, I'm going to assume he means PHP.

I am using HTML with JavaScript (JS).  Any JS example will be very helpful, please.

So you posted in the 'PHP coding help' section?

 

Okay then, well you can still use regex:

 

if (yourDate.match(/^(0[1-9]|[1-2][0-9]|3[0-1])\/(0[1-9]|1[0-2])\/[0-9]{4}$/))
{
    // valid date
}

Well MrAdam just shows you should never assume!

Sorry MrAdam, I'm using HTML, JScript & PHP together.

I will try your solution, thanks;

You should always check it again on server side anyway.

You should always check it again on server side anyway.

Server-side validation = must have

Client-side validation = nice to have
