使用字符串引用时，只有在HTML表单中出现字符串的第一个字 [英] Only first word of string appearing in HTML form when using string-reference

问题描述

我试图让表单文本字段的默认值为预定义的字符串。为此，我使用了一个参考。但是，无论何时我尝试使用PHP或任何类型的形式或形式的引用将表单中的字符串放入表单中，只会添加第一个单词。

以下是描述情况的图片： $ b

有谁知道为什么会发生这种情况，和/或解决办法这个问题？

实际的代码：

 <？php 
 Echo< input type = \text \name = \Address \value = \one two three \>< br>; 
？> 
 
 <？php 
 $ str =一二三; 
 Echo< input type = \text \name = \Address \value =。 $ str。 ><峰; br> 中; 
？> 
 
< input type =textname =Addressvalue =<？php echoone two three;？>>< br> 
< input type =textname =Addressvalue =<？php $ str =one two three; echo $ str;？>>< br> 
< input type =textname =Addressvalue =one two three>< br> 
  

解决方案

您不引用回显的单词。
基本上你这样做：

 < input type =textvalue = one two three /> 
  

但您需要这样做：

 < input type =textvalue =one two three/> 
  

只需在PHP周围添加。

顺便说一句：如果你不想获得XSS，你需要逃避这些。这些攻击非常可怕。在这里阅读： https://www.owasp.org/index.php / Cross-site_Scripting_（XSS）

I'm having a problem with a HTML form and php.

I'm trying to make the default-value of a form-text field to be a pre-defined string. For this I'm using a reference. However, whenever I try to place a string into the form using PHP or references in any kind shape or form, only the first word gets added.

Here is a picture to describe the situation:

Does anyone know why this is happening, and/or a way to work around this issue?

Actual code:

<?php 
    Echo "<input type=\"text\" name=\"Address\" value=\"one two three\"><br>";
?>

<?php 
    $str ="one two three";
    Echo "<input type=\"text\" name=\"Address\" value=" . $str . "><br>";
?>

<input type="text" name="Address" value=<?php echo "one two three";?>><br>
<input type="text" name="Address" value=<?php $str = "one two three"; echo $str;?>><br>
<input type="text" name="Address" value="one two three"><br>

解决方案

You don't quote the echoed words. Basically you do this:

<input type="text" value=one two three />

But you need to do that:

<input type="text" value="one two three" />

Just add "" around the PHP.

BTW: You need to escape these if you don't want to get XSSed. These attacks are quite scary. Read about it here: https://www.owasp.org/index.php/Cross-site_Scripting_(XSS)
