Question

我在PHP中有3个变量，message_id，message_title，message_content。我将这些变量的内容存储在HTML＆＃39; id＆＃39;以便我以后可以使用jQuery。

像这样：

Varibles：

data-slide

这里是＆＃34; ID＆＃34;部分。

如何查看，.img-container { max-height: 300px; overflow: hidden; } .img-container img { max-height: 100%; max-width: 100%; }，$id_variable = $rows['id_mensagem']; $message_title_edit = $rows['title_text']; $message_content_edit = $rows['txt_mensagem'];，echo '<a href="#" class="edit_message" id='.$id_variable.' message='.$message_content_edit.' titulo ='.$message_title_edit .' data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>';

我的问题在哪里：

Id消息＆amp; titulo将数据存储在第一个空白区域内。

像这样：

id=$id_variable

回声/输出：

message = $message_content_edit

Answer 1

这是因为你从不打印任何引号。

echo '<a href="#" class="edit_message" id='.$id_variable.' message='.$message_content_edit.' titulo ='.$message_title_edit .' data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>';

将实际评估为

<a href="#" class="edit_message" id=10 message=Some content titulo=Just some title data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>

哪个不是有效的HTML，所以浏览器/解释器会尝试猜测你的意思。

您需要在打印输出中添加引号

echo '<a href="#" class="edit_message" id="'.$id_variable.'" message="'.$message_content_edit.'" titulo ="'.$message_title_edit .'" data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>';

Answer 2

你需要正确引用它们，试试：

 echo '<a href="#" class="edit_message" id="'.$id_variable.'" message="'.$message_content_edit.'" titulo ="'.$message_title_edit .'" data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>';

Answer 3

你需要在值周围添加“”，titulo在等于之前有一个空格。

看起来您可能在变量中有一些消息信息，因此在输出之前可能需要对变量进行html编码，这样如果$ message_content_edit包含“那么它就不会破坏HTML，例如

echo '<a href="#" class="edit_message" id="' . $id_variable . '" message="' . htmlspecialchars($message_content_edit) . '" titulo="' . htmlspecialchars($message_title_edit) . '" data-toggle="modal" data-target="#open_modal_edit">Detalhes </a>';
