PHP_SELF调用同一个文件

发布时间：2020-12-13 21:46:34 所属栏目：PHP教程来源：网络整理

导读：?phpif(isset($_POST['submit'])) { $name = $_POST['name']; echo "User Has submitted the form and entered this name : b $name /b";}?form method="post" action="?php echo $_SERVER['PHP_SELF']; ?" input type="text" name="name"br input type="sub

<?php
if(isset($_POST['submit'])) 
{ 
    $name = $_POST['name'];
    echo "User Has submitted the form and entered this name : <b> $name </b>";

}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
   <input type="text" name="name"><br>
   <input type="submit" name="submit" value="Submit Form"><br>
</form>

我希望只有在提交后运行部分并且在单击提交表单按钮后才能看到显示表单

解决方法

在其他部分写下你的html表单代码.

<?php
if(isset($_POST['submit'])) 
{ 
    $name = $_POST['name'];
    echo "User Has submitted the form and entered this name : <b> $name </b>";

} else {
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
   <input type="text" name="name"><br>
   <input type="submit" name="submit" value="Submit Form"><br>
</form>

<?php } ?>
