开始对此表单感到沮丧。我正在将html内容提交到我的数据库，以便存储和检索以在我的前端显示。我已确保使用htmlspecialchars()，但是，我保存的所有代码都会被删除为纯文本。
我已经阅读了大量与我的问题几乎相同的帖子，但没有找到合适的答案。
以下是我遇到问题的代码：
<li>
<label for="summary">Article Summary</label>
<textarea name="summary" id="summary" placeholder="Brief description of the article" required maxlength="1000" style="height: 5em;"><?php echo htmlspecialchars( $results['article']->summary )?></textarea>
<script>
CKEDITOR.replace( 'summary', {
filebrowserBrowseUrl: 'wysiwyg/kcfinder/browse.php? opener=ckeditor&type=files',
filebrowserImageBrowseUrl: 'wysiwyg/kcfinder/browse.php? opener=ckeditor&type=images',
filebrowserFlashBrowseUrl: 'wysiwyg/kcfinder/browse.php? opener=ckeditor&type=flash',
filebrowserUploadUrl: 'wysiwyg/kcfinder/upload.php? opener=ckeditor&type=files',
filebrowserImageUploadUrl: 'wysiwyg/kcfinder/upload.php? opener=ckeditor&type=images',
filebrowserFlashUploadUrl: 'wysiwyg/kcfinder/upload.php? opener=ckeditor&type=flash'
});
</script>
</li>
以下是我输入的一个示例：
<p><img alt="" src="/wysiwyg/kcfinder/upload/images/plymouth.png" style="height:323px; width:549px" /></p>
这是输出：
pimg alt"" src"wysiwygkcfinderuploadimagesplymouth.png" style"height:323px width:549px" p
它提交到我的数据库，它被检索并显示在我的前端，只是没有html。此外，该输出是它存储在数据库中的方式。
这里发生了什么？

答案 0 :(得分：0)
确定。所以我想出了问题所在。
在php代码中有preg_replace字符串，它从我的提交中删除了html标记。删除代码允许我以所需的方式存储所有内容。
需要从处理表单提交的部分中删除行preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "",以保留html标记。
删除此行时，请务必从字符串末尾删除额外的)，否则您将生成php error: unexpected ')' on line xx
