表单提交复选框值

I have a bike
I have a car

I know when the form is submitted the value will be vehicle=Bike&vehicle=Car if both are ticked

Is there a way to make the value to be vehicle=Bike,Car

Put them into one variable then separated in a comma

    Since you are using POST and multiple check boxes, set the name of each check box like this:

    <input type="checkbox" name="vehicle[]" value="Bike">
    <input type="checkbox" name="vehicle[]" value="Car">
    

    Then when your form is submitted you will receive an array of all the checked boxes and their values in the array:

    $_POST['vehicle'][];
    

    Now if both boxes are checked you can retrieve the values in a foreach loop:

    foreach($_POST['vehicle'] as $type){
       echo "Type = ".$type;
    }
    

    With this you will get an output of

    Type = Bike
    Type = Car

    Try this one,

    <input type="hidden" name="vechiclesStr" id="vechiclesStr">
    
    
    //on submitting,
    document.getElementById("vechiclesStr").value = document.formname.vechicle.join();
