如何在php的文本框中显示带有空格的整个变量 [英] how to display the entire variable with space in textbox in php

问题描述

我想在文本框中显示带有空格的值.数据库值是usman road".但是在文本框中它只显示usman".

I want to display the value with space in text box.database value is "usman road". But in text box it shows only "usman".

            $value="select * from employee where e_id=$ses";
            $value1=mysql_query($value);
            $vfet=mysql_fetch_assoc($value1);

   echo '<p>First Name<input type="text" name="f" size=18 maxlength=50 style="background-color:transparent;border:0px solid white;" readonly value='.$vfet['e_first_name'].'></p>';

推荐答案

在 value 周围加上引号

Put quotes around value

... value="'.$vfet['e_first_name'].'"...

您拥有的是无效的 html 并破坏了空间上的值

What you have is is invalid html and breaks the value on the space

... value='.$vfet['e_first_name'].' ...  // value = john doe
                                                 ^

修改后会变成

value = "john doe"

要对属性使用不带引号的值，您必须遵循以下 HTML 规范

To use unquoted value for attributes you have to follow the following HTML specifications

未加引号的属性值通过提供以下内容来指定部分完全按照以下顺序:

An unquoted attribute value is specified by providing the following parts in exactly the following order:

1.一个属性名

2. 零个或多个空格字符

2.zero or more space characters

3.单个="；字符

4. 零个或多个空格字符

4.zero or more space characters

5.一个属性值

除了对属性值的一般要求之外，还有一个未加引号的属性值有以下限制:

In addition to the general requirements for attribute values, an unquoted attribute value has the following restrictions:

• 不得 >包含任何文字空格字符

• must not > contain any literal space characters

• 不得包含任何"、"、>="、>"、<"或`"，字符

• must not contain any """, "'",> "=", ">", "<", or "`", characters

不能是空字符串

因为你的值有一个空格，它违反了规则:)

Since your value has a space, it breaks the rules :)
