我有一个带有文本输入和文件上传的表单。我在下面编写的代码基本上可以工作（需要额外的功能，我将在一个单独的问题中询问）但我想知道是否有一种更简洁、更简洁的方式来编写它。我是 php 的新手，任何帮助将不胜感激。

如果有人尝试提交表单并且字段为空，或者选择的文件类型不是正确的类型或大小，我想在每个输入中显示一条错误消息。在下面的代码中，我显示了一条独特的消息，但再想一想，如果有某种方法可以通过这样做使这段代码变得更好，我可以说“必需”。

我尝试使用 jQuery 验证插件，但无法让它与文件上传一起工作（这超出了我对 jQuery/Ajax/PHP 的理解），所以这是我想出的解决方案。

        <?php require_once('../scripts/lcoa.php'); ?>
        <?php 
        if (isset($_GET['jobid'])) {
        $jobid = $_GET['jobid'];
        }
        if (isset($_GET['jobtitle'])) {
        $jobtitle = $_GET['jobtitle'];
        }
         //This is the directory where resumes will be saved 
        $target = "../careers/resumes/"; 
        $target = $target . basename( $_FILES['resume']['name']); 
        $resume=($_FILES['resume']['name']);
        $type = ($_FILES['resume']['type']);
        $extension = strtolower(substr($resume, strpos($resume, '.') + 1)); 
        $size = ($_FILES['resume']['size']);
        $max_size = 3145728;
        $name  = ($_POST['name']);
        $email  = ($_POST['email']);
        $phone  = ($_POST['phone']);
        $jobid = ($_POST['jobid']);
        $jobtitle = ($_POST['jobtitle']);
        $cover = ($_POST['coverletter']);

        if(isset($name)){
            if (empty ($name)){
                ?>
                <script type="text/javascript">
                    $(document).ready(function() {
                       $('#applicant-name').before('<p class="error">Please provide your full name. </p>');          
                    });
                </script> 
                <?php
            }
        }
        if(isset($email)){
            if (empty ($email)){
                ?>
                <script type="text/javascript">

                    });
                </script> 
                <?php
            }
        }
        if(isset($phone)){
            if (empty ($phone)){
                ?>
                <script type="text/javascript">
                    $(document).ready(function() {

                </script> 
                <?php
            }
        }

        //Writes the resume to the server 
        if (isset ($resume)) {
            if (!empty ($resume)){
                if(($extension=='doc'||$extension=='docx'||$extension=='txt'||$extension=='pdf')&&($type=='application/pdf'||'application/msword'||'application/vnd.openxmlformats-officedocument.wordprocessingml.document'||'text/plain')&&$size<=$max_size) {
                if(move_uploaded_file($_FILES['resume']['tmp_name'], $target)) { 
                     //Writes the information to the database

                mysql_select_db($database_lcoa, $lcoa);
                $Result1 = mysql_query($insertSQL, $lcoa) or die(mysql_error());

只是给你一些其他领域的想法，你自己试试

    //php
    $name=$_POST['name'];
    $email=$_POST['email'];
    $error=array();
    if(isset($name)){
        if (empty ($name)){
     $error['name']="<p class='error'>Please provide your full name. </p>";
        }
    }
    if(isset($email)){
        if (empty ($email)){
     $error['email']="<p class='error'>Please provide correct email. </p>";
        }
    }

    //HTML 

<form action="" name"myform">

<?php if(!empty($error['name'])){ echo $error['name']; } ?>

<input type="text" name="name" value="<?php if(isset($name)){ echo $name; } ?>"/>

<?php if(!empty($error['email'])){ echo $error['email']; } ?>

<input type="text" name="name" value="<?php if(isset($name)){ echo $name; } ?>"/>

</form>

它只是在验证文件上传或必须对电话、电子邮件等使用正则表达式测试时向您展示相同逻辑的想法

希望有意义
