用于复选框的PHP逻辑,我有2个表单和2个MySQL表

标签: php mysql forms logic subscription

保罗在这里。我有两种形式:

  • 一个简单的“注册新闻”输入电子邮件和按钮。

  • 包含姓名,电子邮件,消息的“联系”表单。我还有一个复选框,允许从此表单注册新闻。

您可以在名为test的页面上看到它们: http://butterflyepidemic.com/test/

我不确定如何设置复选框的逻辑,以便两个表单都表现自己。如果订阅者使用注册表单,然后想要向我们发送消息,那么联系表单就不会让他们进展:

  

'此电子邮件地址已注册'

。理想情况下,我认为我们应该接受该消息,无论以前的注册或复选框状态如何。反馈总是有一些积极的说法:

  

'您的邮件已收到'

  

'您的讯息已收到。您的电子邮件已经在此处注册了

,如果不是两条正面信息:

  

'您的邮件已收到并且您已注册'

我是响应式表格的新手。我最初的开发基于本教程:

http://net.tutsplus.com/tutorials/javascript-ajax/building-a-sleek-ajax-signup-form/

使用JS,jQuery,PHP,MySQL,JSON。但现在我有了更多东西的第二种形式。我能够让两个表单成功检查两个字段的表,但现在它的反馈逻辑是错误的。 (编辑:我的意思是'联系'形式的PHP)

用于'注册'表单的HTML:

    <form id="newsletter-signup" action="?action=signup" method="post">
        <label for="signup-email">Sign up for news & events:</label>
        <input type="email" name="signup-email" id="signup-email" placeholder="Your email here..."></input>
        <input type="submit" name="signup-button" id="signup-button" value="Sign Me Up!"></input>
        <p id="signup-response"></p>
    </form>

和'联系'表单的HTML:

    <form id="contact-form" action="?action=contact" method="post">
        <legend>Contact us:</legend>

        <label for="email">Your email: *</label>
        <input type="email" name="contact-email" id="contact-email" placeholder="Your email here..." required></input>

        <label for="name">Your Name: *</label>
        <input type="name" name="contact-name" id="contact-name" placeholder="Your name here..." required></input>

        <label for="message">Your Message: *</label>
        <textarea id="contact-textarea" name="contact-textarea" placeholder="Type your message here..." rows = "8" cols = "35" required></textarea>

        <label for="checkbox">Subscribe to Newsletter?</label>
        <input type="checkbox" name="contact-checkbox" id="contact-checkbox" value="1"></input>

        <p id="contact-response"></p>

        <input type="submit" name="contact-button" id="contact-button"></input>

    </form>

以下是注册表单的PHP:

<?php
//form 1 - signup
//email signup ajax call 
if(isset($_GET['action'])&& $_GET['action'] == 'signup'){
    mysql_connect('***','***','***');  
    mysql_select_db('***');


    //sanitize data
    $email = mysql_real_escape_string($_POST['signup-email']);

    //validate email address - check if input was empty
    if(empty($email)){
        $status = 'error';
        $message = 'You did not enter an email address!';
    }

    else if(!preg_match('/^[^\W][a-zA-Z0-9_]+(\.[a-zA-Z0-9_]+)*\@[a-zA-Z0-9_]+(\.[a-zA-Z0-9_]+)*\.[a-zA-Z]{2,4}$/', $email)){ //validate email address - check if is a valid email address
        $status = 'error';
        $message = 'You have entered an invalid email address!';
    }
    else {

        $existingSignup = mysql_query("SELECT * FROM `signups`, `contact` WHERE signup_email_address='$email' OR contact_email_address='$email'");
        if(mysql_num_rows($existingSignup) < 1){
            $date = date('Y-m-d');
            $time = date('H:i:s');

            $insertSignup = mysql_query("INSERT INTO signups (signup_email_address, signup_date, signup_time) VALUES ('$email','$date','$time')");
            if($insertSignup){
                $status = 'success';
                $message = 'you have been signed up!';  
            }
            else {
                $status = 'error';
                $message = "Oops, there's been a technical error! You have not been signed up.";    
            } 
        }

        else {
            $status = 'error';
            $message = 'This email address has already been registered!';
        }
    }

    //return JSON response
    $data = array(
        'status' => $status,
        'message' => $message
    );

    echo json_encode($data);

    exit;
}

和联系表格的PHP如下:

/*Contact Form*/
//ajax call
if(isset($_GET['action'])&& $_GET['action'] == 'contact'){
    mysql_connect('***','***','***');
    mysql_select_db('***');


    //sanitize data
    $email = mysql_real_escape_string($_POST['contact-email']);

    //validate email address - check if input was empty
    if(empty($email)){
        $status = 'error';
        $message = 'You did not enter an email address!';
    }
    else if(!preg_match('/^[^\W][a-zA-Z0-9_]+(\.[a-zA-Z0-9_]+)*\@[a-zA-Z0-9_]+(\.[a-zA-Z0-9_]+)*\.[a-zA-Z]{2,4}$/', $email)){ //validate email address - check if is a valid email address
        $status = "error";
        $message = "You have entered an invalid email address!";
    }
    else {
        $existingContact = mysql_query("SELECT * FROM `signups`, `contact` WHERE signup_email_address='$email' OR contact_email_address='$email'");   
        if(mysql_num_rows($existingContact) < 1){
            //mysql_free_result($existingContact);
            //database insert code

            if ( isset($_POST['contact-checkbox']) ) {
                $checkbox = $_POST['contact-checkbox'];
            }
            else {
                $checkbox = 0;
            }

            $message = $_POST['contact-textarea'];
            $name = $_POST['contact-name'];
            $date = date('Y-m-d');
            $time = date('H:i:s');

            $insertContact = mysql_query("INSERT INTO contact (contact_email_address, contact_date, contact_time, contact_name, contact_message, contact_checkbox) VALUES ('$email','$date','$time','$name','$message','$checkbox')");
            if($insertContact){
                $status = 'success';
                $message = 'your message has been received';    
            }
            else if ($insertContact && $checkbox = $_POST['contact-checkbox']){
                $status = 'success';
                $message = "your message has been received and you have been signed up";        
            }

            else {
                $status = 'error';
                $message = "Oops, there's been a technical error!"; 
            }
        }

        else {
            $status = 'error';
            $message = 'This email address has already been registered!';
        }
    }

    //return the JSON response
    $data = array(
        'status' => $status,
        'message' => $message
    );

    echo json_encode($data);

    exit;
}
?>

JS'注册'表单:

$(document).ready(function(){
    $('#newsletter-signup').submit(function(){

    //check the form is not currently submitting
    if($(this).data('formsstatus') !== 'submitting'){

        //setup variables
        var form = $(this),
        formData = form.serialize(),
        formUrl = form.attr('action'),
        formMethod = form.attr('method'), 
        responseMsg = $('#signup-response');

        //add status data to form
        form.data('formsstatus','submitting');

        //show response message - waiting
        responseMsg.hide()
                   .addClass('response-waiting')
                   .text('Please Wait...')
                   .fadeIn(200);

        //send data to server to be validated
        $.ajax({
            url: formUrl,
            type: formMethod,
            data: formData,
            success:function(data){
                //setup variables
                var responseData = jQuery.parseJSON(data), 
                    klass = '';

                //response conditional
                switch(responseData.status){
                    case 'error':
                        klass = 'response-error';
                    break;
                    case 'success':
                        klass = 'response-success';
                    break;  
                }

                //show reponse message
                responseMsg.fadeOut(200,function(){
                    $(this).removeClass('response-waiting')
                           .addClass(klass)
                           .text(responseData.message)
                           .fadeIn(200,function(){
                               //set timeout to hide response message
                               setTimeout(function(){
                                   responseMsg.fadeOut(200,function(){
                                       $(this).removeClass(klass);
                                       form.data('formsstatus','idle');
                                   });
                               },3000)
                            });
                });
            }
        });
    }
    //prevent form from submitting
    return false;
    });
})

最后是'联系'表单的JS(与'注册'几乎相同):

$(document).ready(function(){
   $('#contact-form').submit(function(){

    //check the form is not currently submitting
    if($(this).data('formsstatus') !== 'submitting'){ 

        //setup variables
        var form = $(this),
            formData = form.serialize(),
            formUrl = form.attr('action'),
            formMethod = form.attr('method'), 
            responseMsg = $('#contact-response');

        //add status data to form
        form.data('formsstatus','submitting');

        //show response message - waiting
        responseMsg.hide()
                   .addClass('response-waiting')
                   .text('Please Wait...')
                   .fadeIn(200);

        //send data to server
        $.ajax({
            url: formUrl,
            type: formMethod,
            data: formData,
            success:function(data){

                //setup variables
                var responseData = jQuery.parseJSON(data), 
                    klass = '';


                //response conditional
                switch(responseData.status){
                    case 'error':
                        klass = 'response-error';
                    break;
                    case 'success':
                        klass = 'response-success';
                    break;  
                }

                //show reponse message
                responseMsg.fadeOut(200,function(){
                    $(this).removeClass('response-waiting')
                           .addClass(klass)
                           .text(responseData.message)
                           .fadeIn(200,function(){
                               //set timeout to hide response message
                               setTimeout(function(){
                                   responseMsg.fadeOut(200,function(){
                                       $(this).removeClass(klass);
                                       form.data('formsstatus','idle');
                                   });
                               },3000)
                            });
                }); 
            }
        });
    }
    //prevent form from submitting
    return false;
    });
})

这就是代码。我想学习如何设置逻辑以提供适当的反馈,如代码上方的理想示例所示。我会对我可能需要研究的任何关键字/链接/示例感到满意。谢谢,保罗。

1 个答案:

答案 0 :(得分:0)

这对我有用:

步骤1:在phpmyadmin中为想要仅发送消息(无需注册)的人创建第三个名为“contact_only”的MySQL表

CREATE TABLE `contact_only` (
  `contact_only_id` int(10) NOT NULL AUTO_INCREMENT,
  `contact_only_email_address` varchar(250) DEFAULT NULL,
  `contact_only_name` varchar(250) DEFAULT NULL,
  `contact_only_message` varchar(3000) DEFAULT NULL,
  `contact_only_checkbox` tinyint(1) NOT NULL default '0',
  `contact_only_date` date DEFAULT NULL,
  `contact_only_time` time DEFAULT NULL,
  PRIMARY KEY (`contact_only_id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

第2步:在“联系”表格中,使用'if&amp;否则,如果'根据用户是否勾选了复选框提供适当的反馈

if ( isset($_POST['contact-checkbox']) ) {

    $existingContact = mysql_query("SELECT * FROM `signups`, `contact` WHERE signup_email_address='$email' OR contact_email_address='$email'");  
    if(mysql_num_rows($existingContact) < 1){

        $checkbox = $_POST['contact-checkbox'];
        $message = $_POST['contact-textarea'];
        $name = $_POST['contact-name'];
        $date = date('Y-m-d');
        $time = date('H:i:s');

        $insertContact = mysql_query("INSERT INTO contact (contact_email_address, contact_date, contact_time, contact_name, contact_message, contact_checkbox) VALUES ('$email','$date','$time','$name','$message','$checkbox')");

        if($insertContact){
            $status = 'success';
            $message = 'your message has been received and you have been signed up';        
        }
    }
    else {

        $checkbox = $_POST['contact-checkbox'];
        $message = $_POST['contact-textarea'];
        $name = $_POST['contact-name'];
        $date = date('Y-m-d');
        $time = date('H:i:s');

        $insertContact = mysql_query("INSERT INTO contact (contact_email_address, contact_date, contact_time, contact_name, contact_message, contact_checkbox) VALUES ('$email','$date','$time','$name','$message','$checkbox')");

        $status = 'success';
        $message = 'Message received. Note - this email address has already been subscribed!';
    }
}
else if (isset($_POST['contact-checkbox']) == false){
    $checkbox = 0;
    $message = $_POST['contact-textarea'];
    $name = $_POST['contact-name'];
    $date = date('Y-m-d');
    $time = date('H:i:s');

    $insertContactOnly = mysql_query("INSERT INTO contact_only (contact_only_email_address, contact_only_date, contact_only_time, contact_only_name, contact_only_message, contact_only_checkbox) VALUES ('$email','$date','$time','$name','$message','$checkbox')");

    if ($insertContactOnly) {
        $status = 'success';
        $message = 'your message has been received';
    }           
}

else {
    $status = 'error';
    $message = "Oops, there's been a technical error!"; 
}

我对这种方式感到满意,因为它通常比负面反馈更积极,而且总是合适的。以下是此解决方案的链接:
