我在Wordpress网站上工作，并且我正在尝试创建一个表单（带有ajax调用），该表单出现在每个产品页面上。我已经在其他服务器上尝试过，工作得非常好，但是当我将我的代码集成到Wordpress页面时却无法正常工作。我正在使用Woocomerce，因此我尝试修改的php文件是＆＃34; content-single-product.php＆＃34;
我的代码：
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#submit_btn").click(function() {
var proceed = true;
//simple validation at client's end
//loop through each field and we simply change border color to red for invalid fields
$("#contact_form input[required=true], #contact_form textarea[required=true]").each(function(){
$(this).css('border-color','');
if(!$.trim($(this).val())){ //if this field is empty
$(this).css('border-color','red'); //change border color to red
proceed = false; //set do not proceed flag
}
//check invalid email
var email_reg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if($(this).attr("type")=="email" && !email_reg.test($.trim($(this).val()))){
$(this).css('border-color','red'); //change border color to red
proceed = false; //set do not proceed flag
}
});
if(proceed) //everything looks good! proceed...
{
//get input field values data to be sent to server
post_data = {
'user_email' : $('input[name=email]').val(),
'phone_number' : $('input[name=telefon]').val(),
};
//Ajax post data to server
$.post('*the path to php file*', post_data, function(response){
if(response.type == 'error'){ //load json data from server and output message
output = '<div class="error">'+response.text+'</div>';
}else{
output = '<div class="success">'+response.text+'</div>';
//reset values in all input fields
$("#contact_form input[required=true], #contact_form textarea[required=true]").val('');
$("#contact_form #contact_body").slideUp(); //hide form after success
}
$("#contact_form #contact_results").hide().html(output).slideDown();
}, 'json');
}
});
//reset previously set border colors and hide all message on .keyup()
$("#contact_form input[required=true], #contact_form textarea[required=true]").keyup(function() {
$(this).css('border-color','');
$("#result").slideUp();
});
});
</script>
<div style="padding-bottom: 15px; border-bottom: 1px solid #999999;" id="contact_form">
<div id="contact_results"></div>
<div id="contact_body">
<div style="color:#ff0000; font-size:12px;">Title text</div>
<p>
<div style="color:#999999; font-size:12px;">Description text</div>
</p>
<label><span>Phone: </span>
<input type="text" name="telefon" maxlength="15" required="true" placeholder="Phone"/>
</label>
<label><span>E-mail: </span>
<input type="email" name="email" required="true" class="input-field" placeholder="E-mail adress"/>
</label>
<label>
<span> </span><input type="submit" id="submit_btn" value="Order now" />
</label>
</div>
</div>
PHP代码是
<?php
if($_POST)
{
$to_email = "email@email.com"; //Recipient email, Replace with own email here
//check if its an ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
$output = json_encode(array( //create JSON data
'type'=>'error',
'text' => 'Sorry Request must be Ajax POST'
));
die($output); //exit script outputting json data
}
//Sanitize input data using PHP filter_var().
$user_email = filter_var($_POST["user_email"], FILTER_SANITIZE_EMAIL);
$phone_number = filter_var($_POST["phone_number"], FILTER_SANITIZE_NUMBER_INT);
$url = filter_var($_SERVER['HTTP_REFERER']);
//additional php validation
if(!filter_var($user_email, FILTER_VALIDATE_EMAIL)){ //email validation
$output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
die($output);
}
if(!filter_var($phone_number, FILTER_SANITIZE_NUMBER_FLOAT)){ //check for valid numbers in phone number field
$output = json_encode(array('type'=>'error', 'text' => 'Enter only digits in phone number'));
die($output);
}
//email body
$subject = "Client nou ! - Telefon: ". $phone_number;
$message_body = "\r\nNumar de telefon : ". $phone_number."\r\nClientul este interesat de urmatorul produs : ". $url;
//proceed with PHP email.
$headers = 'From: '.$user_email.'' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
$send_mail = mail($to_email, $subject, $message_body, $headers);
if(!$send_mail)
{
//If mail couldn't be sent output error. Check your PHP email configuration (if it ever happens)
$output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
die($output);
}else{
$output = json_encode(array('type'=>'message', 'text' => '<div style="color:#999999; font-size:12px;">The order was sent. In few moments we will contact you at the phone number <strong>'.$phone_number .'</strong>!</div>'));
die($output);
}
}
?>
我对Wordpress没那么熟悉。我想，我必须以某种方式适应它。这实际上是我的问题。谢谢！

我认为你正在寻找这个： https://codex.wordpress.org/AJAX_in_Plugins
在您的代码中，您需要添加操作帖子数据：
post_data = {
'user_email' : $('input[name=email]').val(),
'phone_number' : $('input[name=telefon]').val(),
'action' : 'my_custom_send_mail',
'nonce' : '<?php wp_create_nonce('mycustom_mail_form_nonce'); ?>'
};
而不是*the path to php file*，您需要致电<?php echo admin_url('admin-ajax.php'); ?>。
然后在functions.php或my-plugin.php中调用函数：
add_action( 'wp_ajax_my_custom_send_mail', 'my_custom_send_mail_callback' );
add_action( 'wp_ajax_nopriv_my_custom_send_mail', 'my_custom_send_mail_callback' );
function my_custom_send_mail_callback(){
if(!check_ajax_referer( 'mycustom_mail_form_nonce', 'nonce' )){
$output = json_encode(array('type'=>'error', 'text' => 'Something went wrong!'));
die($output);
}
$to_email = "email@email.com";
$user_email = sanitize_email($_POST["user_email"]);
$phone_number = filter_var($_POST["phone_number"], FILTER_SANITIZE_NUMBER_INT);
if(!is_email($user_email)){
$output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
die($output);
}
if(!filter_var($phone_number, FILTER_SANITIZE_NUMBER_FLOAT)){ //check for valid numbers in phone number field
$output = json_encode(array('type'=>'error', 'text' => 'Enter only digits in phone number'));
die($output);
}
//email body
$subject = "Client nou ! - Telefon: ". $phone_number;
$message_body = "\r\nNumar de telefon : ". $phone_number."\r\nClientul este interesat de urmatorul produs : ". $url;
//proceed with PHP email.
$headers = 'From: '.$user_email.'' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
$send_mail = wp_mail($to_email, $subject, $message_body, $headers);
if(!$send_mail){
$output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
die($output);
}else{
$output = json_encode(array('type'=>'message', 'text' => '<div style="color:#999999; font-size:12px;">The order was sent. In few moments we will contact you at the phone number <strong>'.$phone_number .'</strong>!</div>'));
die($output);
}
}
