Undefined error when i try to put a disabled="disabled"

Question

I have a select option and put disabled="disabled" so that it cannot be selected, but when I try to press the update button it always give me this error.

error Notice: Undefined index: Province in D:\wamp\www\LTID\Updaterlbet.php on line 35

But when i try to remove the disabled="disabled" it update successfully. But, i want that disabled to be put there so it cannot be selected..

The code

$Province = isset($_GET['fruit']) ? $_GET['fruit'] : '';

if(isset($_POST['update'])){
    $ID = $_GET['ID'];
    $fruit = $_POST['fruit'];
}

HTML

<select name="Province" class="form-control" id="category" onchange="javascript: dynamicdropdown(this.options[this.selectedIndex].value);">
       <option selected="selected" value="<?php echo $fruut; ?>" disabled="disabled"><?php echo $fruit; ?></option>
       <option value="strawberry">strawberry</option>
       <option value="raspberry">raspberry</option>
       <option value="blueberry">blueberry</option>
</select>

I see try it then.. and also I wouldn't suggest you to use inline js — Kim Oliveros, Jun 20 '16 at 00:25
None of the code you are showing is using `Province` as an index. — chris85, Jun 20 '16 at 00:28
just add an ID/Class then call that element on your `` and do the `onclick `event there anyway your a Filipino aren't you (this might be off topic)? — Kim Oliveros, Jun 20 '16 at 00:37
An index is the access point of an array, e.g. `$_GET['test']`, here we are accessing the `test` index of the `$_GET` array. In your code `fruit`, `update`, and `id` are indexes. — chris85, Jun 20 '16 at 00:42

it will always throws an error because the disabled option is always selected base on your code. To get the fix, remove the selected attribute.

Remove: selected="selected"

Now it will look like this

<select name="Province" class="form-control" id="category" onchange="javascript: dynamicdropdown(this.options[this.selectedIndex].value);">
       <option value="<?php echo $Province; ?>" disabled="disabled"><?php echo $Province; ?></option>
       <option value="ALBAY">Albay</option>
       <option value="CAMARINES NORTE">Camarines Norte</option>
       <option value="CAMARINES SUR I">blu</option>
</select>

Or use this piece of code if you want to select the disabled value as default.

<option selected="true" disabled="disabled" <?php echo $Province; ?>><?php echo $Province; ?></option>

do you want the disabled option to be the default selected value? is that what you mean? – claudios Jun 20 '16 at 02:28
It always select what you have selected of course. disabled value will not be selected that's why it's disabled. – claudios Jun 20 '16 at 02:29

You have selected="selected" in your code. Remove that and it should work just fine.
