我有一个表格,其中必须插入以下类型的代码:

<iframe src="https://www.google.com/maps/embed?pb=!1m14!1m8!1m3!1d3035.058400512634!2d-3.6438669999999997!3d40.473973!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0xd422eea55d33c51%3A0x3294408e8e67eff4!2sClinica+Dental+Artidental!5e0!3m2!1ses!2ses!4v1419779677798" width="600" height="450" frameborder="0" style="border:0"></iframe>

我抓住发布的价值如下:

$mapLink = htmlspecialchars($_POST['mapLink'], ENT_QUOTES);

iframe插入如下:

&lt;iframe src=\&quot;https://www.google.com/maps/embed?pb=!1m14!1m8!1m3!1d3035.058400512634!2d-3.6438669999999997!3d40.473973!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0xd422eea55d33c51%3A0x3294408e8e67eff4!2sClinica+Dental+Artidental!5e0!3m2!1ses!2ses!4v1419779677798\&quot; width=\&quot;600\&quot; height=\&quot;450\&quot; frameborder=\&quot;0\&quot; style=\&quot;border:0\&quot;&gt;&lt;/iframe&gt;

如何使用php获取我的初始链接"<iframe src..."并将其打印出来,因为它是最初编写的?没有反斜杠,&amp; quot等

以下是我在MYSQL中插入/更新的方法:

            $editCentro = $con->prepare("UPDATE centros SET  active = :active, nombre = :nombre, zona = :zona, address = :address,
        metro = :metro, zip = :zip, phone = :phone, fax = :fax, email = :email, mapLink = :mapLink, descripcion = :descripcion, horarios = :horarios
        WHERE id = ".$centroId);
        $editCentro->execute(array(':active'=>$active, ':nombre'=> $nombre, ':zona'=>$zona, ':address'=>$address, ':metro'=>$metro, 
        ':zip'=>$zip, ':phone'=>$telefono, ':fax'=>$fax, ':email'=>$email, ':mapLink'=>$mapLink, ':descripcion'=>$descripcion, ':horarios'=>$horarios));

即使没有转义该值,它也会在双引号之前插入反斜杠...

将字符串分配给$mapLink时,您将转义字符串:

$mapLink = htmlspecialchars($_POST['mapLink'], ENT_QUOTES);

如果要按原样将其插入数据库,只需从post中获取值,将其转义。 (另外,这不是你用来阻止SQLi的转义)

要防止SQL注入,请使用mysql绑定,如下所示:

$stmt = $mysqli->prepare("INSERT INTO sometable (fieldA, mapField, fieldC) VALUES (?, ?, ?)");
$stmt->bind_param('sss', $someVar, $mapLink, $otherVar);

查看有关参数绑定in the PHP docs here的更多信息。

如果你有魔术引号的问题,你可以像这样剥离它们:

$mapLink = stripslashes($_POST['mapLink']);

您是否尝试过html_entity_decode

<?php
$orig = "I'll \"walk\" the <b>dog</b> now";

$a = htmlentities($orig);

$b = html_entity_decode($a);

echo $a; // I'll &quot;walk&quot; the &lt;b&gt;dog&lt;/b&gt; now

echo $b; // I'll "walk" the <b>dog</b> now
?>
