PHP Dropdown please select option

Question

How can I use PHP to raise an error if this particular value is selected?

<option>Please Select</option>

Please explain what you are trying to accomplish. What do you mean by "raise an error"? — Ben D

Just like any $_POST'ed data in PHP? give it a value and use == or use empty() and set the value of this option to nothing, like: value="" as shown in atmon3r's answer. — Abdulaziz

May also want to look into HTML5's required attribute on the select element. Will catch some simple errors and in combination with PHP be a good experience for your user. — Matt R.

You can try this:

HTML

<select name="selectoption">
     <option value="">Please Select</option>
</select>

PHP

if (isset($_POST['selectoption']) && $_POST['selectoption'] == '' ) {
   echo 'Error, select an options';
   exit;
}

Check if $_POST is empty
Html:

<select name="category">
     <option value="">Please Select</option>
     <option value="1">Category 1</option>
     <option value="2">Category 2</option>
</select>

and php:

if (empty($_POST['category']) && isset($_POST['category'])) {
        echo 'Error, select category';
        exit;
}

Give it a value too, and check the value in you php with $_POST['foo']

<select name="foo">
<option value="0">Please Select</option>
...
</select>

For me this is better way:

if (isset($_POST['category']) && $_POST['category'] == '' ) {
       echo 'Error, select category';
       exit;
}
