Question

我在youtube上关注如何制作联系表单（https://www.youtube.com/watch?v=9KS2QuFXIs8）以及我的某些部分，因为我的某些PHP代码无法运行...

<?php else: ?>
<p>Thank you for your Message!</p>
<?php endif; ?>

也

<?php if($form_complete === FALSE): ?>

下面使用php的其余代码工作，所以我确定它不是服务器，但可能上面的代码有冒号的事实。这是代码的其余部分。

<?php

// Set email variables
$email_to = 'guomonster@gmail.com';
$email_subject = 'Form submission';

// Set required fields
$required_fields = array('fullname','email','comment');

// set error messages
$error_messages = array(
'fullname' => 'Please enter a Name to proceed.',
'email' => 'Please enter a valid Email Address to continue.',
'comment' => 'Please enter your Message to continue.'
);

// Set form status
$form_complete = FALSE;

// configure validation array
$validation = array();

// check form submittal
if(!empty($_POST)) {
// Sanitise POST array
foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));

// Loop into required fields and make sure they match our needs
foreach($required_fields as $field) {
// the field has been submitted?
if(!array_key_exists($field, $_POST)) array_push($validation, $field);

// check there is information in the field?
if($_POST[$field] == '') array_push($validation, $field);

// validate the email address supplied
if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
}

// basic validation result
if(count($validation) == 0) {
// Prepare our content string
$email_content = 'New Website Comment: ' . "\n\n";

// simple email content
foreach($_POST as $key => $value) {
if($key != 'submit') $email_content .= $key . ': ' . $value . "\n";
}

// if validation passed ok then send the email
mail($email_to, $email_subject, $email_content);

// Update form switch
$form_complete = TRUE;
}
}

function validate_email_address($email = FALSE) {
return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;
}

function remove_email_injection($field = FALSE) {
return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
}

?>

在PHP中你应该使用Brackets作为条件代码块。

<?php if ($form_complete === FALSE) { ?>
<p>if-branch</p>
<?php } else { ?>
<p>Thank you for your Message!</p>
<?php } ?>

但是在html中使用PHP代码可能会非常混乱。请尝试以下方法：

<?php
if ($form_complete === FALSE) {
  // do something
} else {
  echo '<p>Thank you for your Message!</p>'
}
?>

简单的PHP命令不起作用？
