How to ensure a <select> form field is submitted when it is disabled?

I have a select form field that I want to mark as "readonly", as in the user cannot modify the value, but the value is still submitted with the form. Using the disabled attribute prevents the user from changing the value, but does not submit the value with the form.

The readonly attribute is only available for input and textarea fields, but that's basically what I want. Is there any way to get that working?

Two possibilities I'm considering include:

  • Instead of disabling the select, disable all of the options and use CSS to gray out the select so it looks like its disabled.
  • Add a click event handler to the submit button so that it enables all of the disabled dropdown menus before submitting the form.

Disable the fields and then enable them before the form is submitted:

jQuery code:

jQuery(function ($) {        
  $('form').bind('submit', function () {
    $(this).find(':input').prop('disabled', false);
  });
});

<select disabled="disabled">
    ....
</select>
<input type="hidden" name="select_name" value="selected value" />

Where select_name is the name that you would normally give the <select>.

Another option.

<select name="myselect" disabled="disabled">
    <option value="myselectedvalue" selected="selected">My Value</option>
    ....
</select>
<input type="hidden" name="myselect" value="myselectedvalue" />

Now with this one, I have noticed that depending on what webserver you are using, you may have to put the hidden input either before, or after the <select>.

If my memory serves me correctly, with IIS, you put it before, with Apache you put it after. As always, testing is key.

Or use some JavaScript to change the name of the select and set it to disabled. This way the select is still submitted, but using a name you aren't checking.

I found a workable solution: remove all the elements except the selected one. You can then change the style to something that looks disabled as well. Using jQuery:

jQuery(function($) {
    $('form').submit(function(){
        $('select option:not(:selected)', this).remove();
    });
});
