how to exclude the first value of the option in a select-CodePudding

I have a little problem and i don't know how to fix it.

I have a select like this in my request

<select  name="start_time" id="time">
      <option>Aanvangstijd *</option>
      <option value="11:00" id="time">11:00</option>
      <option value="11:30" id="time">11:30</option>
      <option value="12:00" id="time">12:00</option>
</select>

But the first option <option>Aanvangstijd *</option> should not pass the validation in my request, but it of course does because it has a value.

Here is my Request

 public function rules()
    {
        return [
            'name' => 'required',
            'phone' => 'required',
            'email' => 'required',
            'msg' => 'required',
            'start_time' => 'required',
            'avg' => 'required',
        ];
    }

So my question is, how can I get it to work that it only passes this validation when an option is passed that isn'tAanvangstijd *`

CodePudding user response：

Laravel has great validation rules so you can be strict and specific about what is allowed in the input, including the date/time format. From what I see, you expect "start_time" input

to be required
to be string
of 5 characters
and to be valid time.

So, we can write just that:

public function rules()
{
    return [
        'name' => 'required',
        'phone' => 'required',
        'email' => 'required',
        'msg' => 'required',
        'start_time' => 'required|string|size:5|date_format:H:i',
        'avg' => 'required',
    ];
}

Maybe you wish to limit the time range between 11:00 and 12:00, or, specifically:

to be equal or after 11:00
and to be equal or before 12:00

So you can add this rules on your validation:

'start_time' => 'required|string|size:5|date_format:H:i|after_or_equal:11:00|before_or_equal:12:00'

Additionaly you may wish to limit "start_time" to be only 11:00, 11:30 or 12:00:

'start_time' => 'required|string|size:5|date_format:H:i|after_or_equal:11:00|before_or_equal:12:00|in:11:00,11:30,12:00',

At the and we can increase our readability by using array syntax:

public
    function rules()
    {
        return [
            'name' => 'required',
            'phone' => 'required',
            'email' => 'required',
            'msg' => 'required',
            'start_time' => [
                'required',
                'string',
                'size:5',
                'date_format:H:i',
                'after_or_equal:11:00',
                'before_or_equal:12:00',
                Rule::in(['11:00', '11:30', '12:00']),
            ],
            'avg' => 'required',
        ];
    }

And, one advice: TRUST NO ONE, NOT EVEN YOU! Even if you wrote frontend code and (you think) you are 100% sure you know what your html form will be sending your backend, please, use good, strict validation rules.
