编写和来自HTML表单编辑PHP配置文件？ [英] Writing and editing a PHP config file from a HTML form?

问题描述

嗨只是寻找一些方向，我有哪几种领域，基本上是我想要做的是保存从表单中输入的PHP配置文件中的数据，也有编辑保存的数据的能力的HTML表单通过访问，并再次提交表单。我想preFER要做到这一点，而无需使用的数据库。

Hi just looking for some direction, I have a HTML form which has several fields and basically what I am wanting to do is save the data entered from the form to a PHP config file and also have the ability to edit the saved data by accessing and submitting the form again. I would prefer to do this without the use of a database.

所以这里有一个例子：

<form method="post" name="config_form">
<div id="field">
<label>Keywords</label>
<br />
<input type="text" name="keyword">
</div>

<br />

<select name="color">
<option value="green">Green</option>
<option value="orange">Orange</option>
<option value="blue">Blue</option>
<option value="red">Red</option>
</select>

</form>

所以用户输入计算机为关键字，并选择颜色蓝色。我想那么这个数据保存到我的config.php文件作为变量让我的其他网站页面来访问这些数据。如果这一切是在一个数组中呢？

So the user enters 'computer' as the keyword and selects the color 'blue'. I want to then save this data into my config.php file as variables allowing my other website pages to access this data. Should this all be in an array as well?

<?php
//config file
$keyword = "computer";
$color = "blue";

?>

此外，当我回去访问窗体我又可以把它使字段从config.php文件与数据pfilled $ P $？

Also when I go back access the form again can I make it so the fields are prefilled with the data from the config.php file?

任何帮助将是非常美联社preciated谢谢！

Any help would be much appreciated thank you!

推荐答案

您可以包括您的配置文件中的主PHP脚本文件：

You can include your configuration file in your main php script file:

// main.php
<? php include("config.php"); ?>

和像这样建的形式：

// main.php
<?php
?>
    <form method="post" name="config_form">
        <div id="field">
            <label>Keywords</label>
            <br />
            <input type="text" name="keyword">
        </div>

        <br />

        <select name="color">
            <option value="green" <? if ($color == "green") echo "SELECTED"; ?> >Green</option>
            <option value="orange" <? if ($color == "orange") echo "SELECTED"; ?> >Orange</option>
            <option value="blue" <? if ($color == "blue") echo "SELECTED"; ?> >Blue</option>
            <option value="red" <? if ($color == "red") echo "SELECTED"; ?> >Red</option>
        </select>

</form>
<?
?>

终于可以保存在你的表单数据的config.php 文件中使用 fopen（）函数和的fwrite（）的形式提交功能：

finally you can save the form data in your config.php file using fopen() and fwrite() functions on form submit:

$key = $_POST["key"];
$color = $_POST["color"];

if ($key != '' && $color != '') {
    $f = fopen('config.php', 'w') or die("can't open file");
    fwrite($f, '<?php $keyword=' . $key . ';$color=' . $color . ';?>');
    fclose($f);
} else { // write default values or show an error message }
