Create Select Box with Options

The HTML Select box is created with an option list, and it is used to create a dropdown list of possible options. A user clicks on the select dropdown and chooses one of the options based on the requirement. We can also use multiple tags with the select tag, which lets users select multiple values from the dropdown list.

<form action="" method="post">
    <select name="Fruit">
        <option value="" disabled selected>Choose option</option>
        <option value="Apple">Apple</option>
        <option value="Banana">Banana</option>
        <option value="Coconut">Coconut</option>
        <option value="Blueberry">Blueberry</option>
        <option value="Strawberry">Strawberry</option>
    </select>
    <input type="submit" name="submit" vlaue="Choose options">
</form>

PHP 8 Get Single Selected Values of Select Box

We used $_POST to get the select option value if the value is selected it will be displayed to user else we will throw the error message.

<?php
    if(isset($_POST['submit'])){
    if(!empty($_POST['Fruit'])) {
        $selected = $_POST['Fruit'];
        echo 'You have chosen: ' . $selected;
    } else {
        echo 'Please select the value.';
    }
    }
?>

We added some CSS to add custom styling for select dropdown, You can check out the full code example below.

    <?php
      if(isset($_POST['submit'])){
        if(!empty($_POST['Fruit'])) {
          $selected = $_POST['Fruit'];
          echo 'You have chosen: ' . $selected;
        } else {
          echo 'Please select the value.';
        }
      }
    ?>
  </div>
</body>
</html>

Get Multiple Selected Values of Select Dropdown in PHP

In this step we will learn can a user select multiple selected values from a select options box. Add the multiple tag with select tag also define array with name property.

<select name="Fruits[]" multiple>
  <option value="" disabled selected>Choose option</option>
  <option value="Apple">Apple</option>
  <option value="Banana">Banana</option>
  <option value="Coconut">Coconut</option>
  <option value="Blueberry">Blueberry</option>
  <option value="Strawberry">Strawberry</option>
</select>

Make sure the Fruits array is not empty, run a foreach loop to iterate over every value of the select dropdown. Display the selected values else show the error message to the user.

<?php
  if(isset($_POST['submit'])){
    if(!empty($_POST['Fruits'])) {
      foreach($_POST['Fruits'] as $selected){
        echo '  ' . $selected;
      }          
    } else {
      echo 'Please select the value.';
    }
  }
?>

Here is the final code of multi select box.

<!doctype html>

</head>
<body>

    <?php
      if(isset($_POST['submit'])){
        if(!empty($_POST['Fruits'])) {
          foreach($_POST['Fruits'] as $selected){
            echo '  ' . $selected;

        } else {
