Validation if the value exists else no validation-CodePudding

So, this is what i've tried already.

$regex = '/^(https?:\/\/)?([\da-z\.-] )\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/';
    $rules = [
    'nextcontactSchool' => 'nullable|digits_between:7,10',
    'websiteSchool' => 'nullable|regex:' . $regex,
    ];

I did this in a controller once i figured that i can't properly make use of a rule. But the problem here is that, I cant seem to pass the empty data to the database and everytime that i do that, i get a error message.

Can you please help me out?

CodePudding user response：

You can use nullable and it will pass if websiteSchool and nextcontactSchool are not present

$request->validate([
    'websiteSchool' => ['nullable', 'url'],
    'nextcontactSchool' => ['nullable', 'digits_between:7,10']
]);

If this is not what you need, consider the following validation methods:

so, i came to know the answer behind it. when using nullable it sends a null value for sure but it send's the nullable value in terms of a string. so rather than comparing it to null, we would be comparing it to 'null'.

e.g:

if($variable!='null'){
//do something
}
