如何使用PHP从输入文本框中获取值？我的代码如下：

<body>
    <form action="new.php" method="post">
        Date: <input name="date" type="text" value="Saturday, October 11, 2014" />
              <input name="ok" type="submit" value="Submit" />
     <?php      
        if(isset($_POST['ok'])){
            $day=$_POST['date'];
            echo "today's date is".$day;//how do I echo only the word Saturday?
        }else   
    ?>
    </form>
</body>

我想echo只有'＃34;星期六＆＃34;这个词，但我不确定如何做到这一点，因为我的$day变量包含整个日期字符串。有什么帮助吗？

Answer 1

你可以通过超级全局变量从表单中获取任何数据：$ _POST ['name_of _input']如果你使用方法获取，你可以使用方法发布或$ _GET ['name_of_input']。这个HTML标签

<html>
<body>
<form action="name_of_page_process.php" method="post">
<input type="text" name="days" placeholder="enter name of day" />
<input type="submit" name="sub" />
</form>
</body>
</html>



    this code of process by php :

<?php 
if(isset($_post['sub'])){
$day=$_post['days'];
echo "name of day is".$day;

}

?>

您可以使用爆炸功能：

<body>
<form action="new.php" method="post">
    Date: <input name="date" type="text" value="Saturday, October 11, 2014" />
          <input name="ok" type="submit" value="Submit" />
 <?php      
    if(isset($_POST['ok'])){
        $day=$_POST['date'];
        $pieces = explode(",", $day);
        echo "today's date is ".$pieces[0]; // show only word "Saturday"
    }else   
?>
</form>

这应该对你有用

<body>
    <form action="" method="get">
        Date: <input type="text" name='day' value="Saturday, October 1<?php ?>1, 2014" />
<input type="submit">
    </form>
</body>


<?php  


     $day = $_GET["day"] ;
     if(isset($day)):
     echo strtok($day, ",");

     endif;   


?>
