如何从按钮获取值

Question

I have a form which goes through three steps. In step 2, I am asking the user to select a speciality by clicking the corresponding button. If they click a button, they should move to the 3^rd and final step.

Here is the button code:

<button class="btn btn-primary nextBtn btn-proffessional "
        type="button" name="hair_stylist" >HAIR STYLIST</button>
<button class="btn btn-primary nextBtn btn-proffessional " 
        type="button" name="cosmetologist" >COSMETOLOGIST</button>
<button class="btn btn-primary nextBtn btn-proffessional " 
        type="button" name="makeup_artist" >MAKEUP ARTIST</button>
<button class="btn btn-primary nextBtn btn-proffessional " 
        type="button" name="barber" >BARBER</button>
<button class="btn btn-primary nextBtn btn-proffessional " 
        type="button" name="esthetician" >ESTHETICIAN</button>
<button class="btn btn-primary nextBtn btn-proffessional " 
        type="button" name="nail_technitian" >NAIL TECHNITIAN</button>

I don't think name will work here. Is there anything that can be done with data-*? How can I send and grab this value in PHP when the form is submitted?

Answer 1

Having a name is fine and necessary.

There are two problems.

1. You need actually have a value in order to send a value
2. You need the button to be a submit button in order to submit the form

Such:

<button 
    class="btn btn-primary nextBtn btn-proffessional"
    type="submit" 
    name="profession"
    value="hair_stylist">
        Hair Stylist 
</button>

Then in PHP you can simply:

do_something_with($_POST["profession"]);
