祝大家有美好的一天，
我正在尝试使用 php 创建一个 CMS，但在执行以下操作时遇到了麻烦：
我想删除、编辑或向我的页面添加信息，为此我使用了几个按钮和 AJAX 将表单加载到显示 div。我让按钮删除工作完美，但是当我尝试添加和编辑按钮时它不起作用，因为他们要求附加一些也包含 php 代码的 html 文本，因此没有 PHP 解释器来读取它。
我的做法：
<div class="displayHere col-xs-12"> </div>是空的。- 我单击添加按钮，它转到 ajax.php 并附加表单和表单验证。
- 我填写了表单并单击 add_document，表单验证（php）检查数据并上传文档（如果可能）并设置一些输出变量。
我怎样才能获得这个功能？可能我正在处理这个问题，我希望你们中的一些人可以与我分享你的经验。
例如，对于 add 功能，我想获得这个功能：
<div id="bodyDiv">
<!--HEADER-->
<header id="header" class=" row">
<?php
include 'includes/loadHeader.php';
echo '<nav class="col-xs-6 cms_nav">
<ul>
<li><input id="buttonAdd" type="submit" class="button buttonFuncitonality" name="AÑADIR" value="AÑADIR" /></li>
</ul>
</nav>';
?>
<div class="displayHere col-xs-12">

在我的网站中，我有一个添加按钮，应该使用 AJAX 上传表单验证。
<?php
//echo "piece of shit";
if (isset($_POST['action'])) {
switch ($_POST['action']) {
case 'AÑADIR': //ADD FUNCTIONALITY
add_document();
break;
default:
echo "La accion no se indentifica\n" ;
break;
}
}
function add_document() {
echo ' <div id="insertForm" class="col-xs-12 shareholdersForm">
<h3>Insertar</h3>
<form method="POST" enctype="multipart/form-data">
<input class="col-xs-12 form-control <?php if( !empty($nameErr) ) {echo "boxError alert-danger " ;} ?> " value="<?php if( !$success ) {echo $name;}?>" type="text" name="name" placeholder="<?php if( !empty($nameErr) ) {echo $nameErr;}else{ echo "nombre";}?>">

<select class="col-xs-12 form-control <?php if( !empty($typeErr) ) {echo "boxError alert-danger" ;} ?> " name="type">
<option value="hechosRelevantes">hecho relevantes</option>
<option value="informacionEmpresa">informacion empresa</option>
<option value="informacionFinanciera">informacion financiera</option>
</select>
<input class="col-xs-12" type="file" name="documentPDF" accept="application/pdf" >
<span class="error col-xs-12" style="float:left"> <?php if( !empty($fileErr) ) {echo "* ". $fileErr;} ?> </span>
<button class="btn btn-default" type="submit" name="insert">Añadir</button>
<?php if ( !empty($result) ){ echo $result; } ?>
</form>
</div>
</div>';
}
function load_delete_document_form($id) {
echo ' <div id="deleteForm" class="col-xs-12 shareholdersForm">
<h3>Eliminar '. $id.'</h3>
<form id="'.$id.'" method="POST">
<button class="btn btn-default buttonFunctionality" type="submit" name="Delete" value="Delete">Eliminar</button>
</form>
</div>
';
exit;
}
?>
要使用该 AJAX 代码，我在我的网站中使用了这个 jquery 函数：
<script>
//$(document).ready(function(){
$("body").on("click",".buttonFunctionality", function(){
if($('.displayHere').length !== 0){
$('.displayHere').children().remove()
}
var action = $(this).val();
var id = $(this).parent().attr('id');
console.log(action + " " + id);
$.post("includes/ajax.php",{ action: action, id: id}, function(data, status){
console.log("click1 " + id );
console.log("data " + data);
$('.displayHere').append(data); // This append will append the code I will need in my page
});
});
//});
</script>
由于我的代码，我得到了带有大量 php 代码的表单，没有解释。
