Question

我正在尝试为用户信息编写一个表单，以跟踪谁从我的网站下载文件。我是PHP的新手，之前从未使用过WordPress，所以请光临我。

我从this website下载了一个PHP表单验证器，我尝试用客户端验证模仿示例3，这是我想出来的（请原谅长度，但我认为有必要理解一切）：

<?php
require_once(ABSPATH. '/wp-includes/FormValidator/include/formvalidator.php');

$validation_errors='';
if(isset($_POST['submitButton']))
{// We need to validate only after the form is submitted

    //Setup Server side Validations
    //Please note that the element name is case sensitive 
    $validator = new FormValidator();
    $validator->addValidation("firstname","req","Please fill in your First Name");
    $validator->addValidation("firstname","alpha","Only letters a-z/A-Z are allowed for your First Name");
    $validator->addValidation("lasttname","req","Please fill in your Last Name");
    $validator->addValidation("lastname","alpha","Only letters a-z/A-Z are allowed for your Last Name");

    //Then validate the form
    if($validator->ValidateForm())
    {
        //If the validations succeeded, proceed with form processing
        addUserDataToDB();
    }
    else
    {
        //Validations failed. Display Errors.
        $error_hash = $validator->GetErrors();
        foreach($error_hash as $inpname => $inp_err)
        {
           $validation_errors .= "<p>$inpname : $inp_err</p>\n";
        }        
    }
}//if

$first_name  = isset($_POST['firstname'])?$_POST['firstname']:'';
$last_name = isset($_POST['lastname'])?$_POST['lastname']:'';
?>

        'lastname' => $lastname ) );

    //Redirect to download page
    wp_redirect('Whitepaper.htm');
    exit();

?>

<!-- client-side Form Validations:
Uses the form validation script from JavaScript-coder.com
See: http://www.javascript-coder.com/html-form/javascript-form-validation.phtml
-->
<script type='text/javascript'>
    console.log("javascript ran");
    var frmvalidator  = new Validator("DownloadUserDataForm");
    frmvalidator.EnableOnPageErrorDisplay();
    frmvalidator.EnableMsgsTogether();
    frmvalidator.addValidation("firstname","req","Please fill in your First Name");
    frmvalidator.addValidation("firstname","alpha","Only letters a-z/A-Z are allowed for your First Name");
    frmvalidator.addValidation("lasttname","req","Please fill in your Last Name");
    frmvalidator.addValidation("lastname","alpha","Only letters a-z/A-Z are allowed for your Last Name");
</script>

所有发生的事情都是页面刷新，没有错误或验证，而且它似乎没有写入$wpdb，因为我有一个查询db表的管理页面，它出现空（它也没有't wp_redirect()喜欢它。由于某些原因，即使地址看起来正确，它也找不到javascript文件。

修改：以下是来自javascript的错误：

GET HTTP：///home/public_html/wp-includes/FormValidator/scripts/gen_validatorv31.js 404（未找到）

Answer 1

对于您的javascript错误，请尝试更改此行：

<script type='text/javascript' src='<?php echo ABSPATH.'/wp-includes/FormValidator/scripts/gen_validatorv31.js' ?>'>

到

<script type="text/javascript" src="<?php echo ABSPATH; ?>/wp-includes/FormValidator/scripts/gen_validatorv31.js"></script>

WordPress：PHP表单验证：似乎不起作用
