PHP POST单页表单 - 最初隐藏验证等

标签: php html forms validation post

这是我第一次使用PHP,我将一个表单拼凑在一起。问题是,当您第一次访问该页面时,它会显示“请输入您的电子邮件地址,以便我们与您联系”,但我只想在按下提交按钮后出现错误/成功消息。

此外,我希望所有消息在输出时都包含在div中。

我读了一篇建议使用如下内容的帖子,但是当我尝试实现时,按下提交时不会显示任何消息:

if (isset($_POST['submit'])) 
{ 
    // Process Form
}
else
{
    // Show Form
}

无论如何,这是我的完整代码:

<?php 
 $to = "me@gmail.com" ; 
 $from = $_REQUEST['Email'] ; 
 $name = $_REQUEST['Name'] ; 
 $headers = "From: $from"; 
 $subject = "Web Contact Data";
 $startmonth = $_REQUEST['StartMonth'];
 $startyear = $_REQUEST['StartYear'];
 $endmonth = $_REQUEST['EndMonth'];
 $endyear = $_REQUEST['EndYear'];
 $message = $_REQUEST['Message'];

 $fields = array(); 
 $fields{"Name"} = "Name"; 
 $fields{"Email"} = "Email"; 
 $fields{"Phone"} = "Phone"; 

 $selectedProjects  = 'None';
if(isset($_POST['projects']) && is_array($_POST['projects']) && count($_POST['projects']) > 0){
    $selectedProjects = implode(', ', $_POST['projects']);
}
 $selectedSkills  = 'None';
if(isset($_POST['skills']) && is_array($_POST['skills']) && count($_POST['skills']) > 0){
    $selectedSkills = implode(', ', $_POST['skills']);
}
$selectedNoRush  = 'None';
if(isset($_POST['norush']) && is_array($_POST['norush']) && count($_POST['norush']) > 0){
    $NoRush= implode(', ', $_POST['norush']);
}
$selectedWhenReady  = 'None';
if(isset($_POST['whenready']) && is_array($_POST['whenready']) && count($_POST['whenready']) > 0){
    $WhenReady= implode(', ', $_POST['whenready']);
}
$selectedBudget  = 'None';
if(isset($_POST['budget']) && is_array($_POST['budget']) && count($_POST['budget']) > 0){
    $selectedBudget= implode(', ', $_POST['budget']);
} 

$body = "We have received the following information:\n\n"; foreach($fields as $a => $b){$body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]);}
$body .= "\n" . 'Selected Projects: ' . $selectedProjects . "\n";
$body .= 'Selected Skills: ' . $selectedSkills . "\n\n";
$body .= 'Start Date: ' . $startmonth . " " . $startyear . " " . $NoRush . "\n";
$body .= 'End Date: ' . $endmonth . " " . $endyear . " " . $WhenReady . "\n";
$body .= 'Budget: ' . $selectedBudget . "\n\n";
$body .= 'Message:' . $message . "\n";



 $headers2 = "From: me@gmail.com"; 
 $subject2 = "Thank you for contacting us"; 
 $autoreply = "Thank you for contacting us. Somebody will get back to you as soon as possible, usually within 48 hours.";


 if($from == '') {print "Please enter your email address so we can contact you.";} 
 else { 
 if($name == '') {print "Please enter your name so we know who sent this.";} 
 else {
 if($message == '') {print "Please give a brief description so we can understand how best to help.";} 
 else {
 $send = mail($to, $subject, $body, $headers); 
 $send2 = mail($from, $subject2, $autoreply, $headers2); 
 if($send) 
 {print "Thank you. Your request has been successfully submitted.";} 
 else 
 {print "We encountered an error sending your mail, please check your details are correct or email us at hello@lyonempire.co.uk"; } 
}}}
 ?>

感谢。

PS。如果有人想指出什么是更好的括号和布局代码的做法,请随意。我知道我可以做得更好,但不确定如何。

答案 0 :(得分:0)

<强>编辑: 正如评论部分所述,第一部分是不正确的,我很抱歉给出了错误的答案。我不知道动作属性在html 5上是可选的,应该在发布前完成我的研究。道歉。


这是不正确的:

  

没有任何内容显示,因为您没有指定将在哪个php文件中处理表单。   编辑您的表单标签(将index.php替换为您的php文件名):

<form action="index.php" method="post">

此外,

的“提交”部分
isset($_POST['submit'])

必须与提交按钮的名称匹配:

<input type="submit" name="send" value="Submit Details Now!">

应该是:

<input type="submit" name="submit" value="Submit Details Now!">
