Using $_POST to get select option value from HTML

Use this way:

$selectOption = $_POST['taskOption'];

But it is always better to give values to your <option> tags.

<select name="taskOption">  <option value="1">First</option>  <option value="2">Second</option>  <option value="3">Third</option></select>

You can access values in the $_POST array by their key. $_POST is an associative array, so to access taskOption you would use $_POST['taskOption'];.

Make sure to check if it exists in the $_POST array before proceeding though.

<form method="post" action="process.php">  <select name="taskOption">    <option value="first">First</option>    <option value="second">Second</option>    <option value="third">Third</option>  </select>  <input type="submit" value="Submit the form"/></form>

process.php

<?php   $option = isset($_POST['taskOption']) ? $_POST['taskOption'] : false;   if ($option) {      echo htmlentities($_POST['taskOption'], ENT_QUOTES, "UTF-8");   } else {     echo "task option is required";     exit;    }

You can do it like this, too:

<?phpif(isset($_POST['select1'])){    $select1 = $_POST['select1'];    switch ($select1) {        case 'value1':            echo 'this is value1<br/>';            break;        case 'value2':            echo 'value2<br/>';            break;        default:            # code...            break;    }}?><form action="" method="post">    <select name="select1">        <option value="value1">Value 1</option>        <option value="value2">Value 2</option>    </select>    <input type="submit" name="submit" value="Go"/></form>
