將HTML表單dissepear後提交

Question

我怎樣才能使HTML表單提交dissepear後，它會顯示按鈕，使形式再次重現疏通結果呢？

<?php 
if(isset($_POST['submit'])) 
{ 
    $name = $_POST['name']; 
    echo "User Has submitted the form and entered this name : <b> $name </b>"; 
    echo "<br>You can use the following form again to enter a new name."; 
} 
?> 
<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> 

Answer 1

注：else條件包裹HTML

<?php 
if(isset($_POST['submit'])) 
{ 
    $name = $_POST['name']; 
    echo "User Has submitted the form and entered this name : <b> $name </b>"; 
    echo "<br>You can use the following form again to enter a new name."; 
} 
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 }?>

你必須只需插入你的整個form內else部分

<?php 
if(isset($_POST['submit'])) 
{ 
    $name = $_POST['name']; 
    echo "User Has submitted the form and entered this name : <b> $name </b>"; 
    echo "<br>You can use the following form again to enter a new name."; 
    echo "<a href='your_page.php'> Page</a>"; 
} 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> 
<?ph } ?>

<form id="myform" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> 
    <input type="text" name="name"><br> 
    <input type="submit" name="submit" value="Submit Form" onclick="document.getElementById('myform').style.display='none'"><br> 
</form>
