php $ _GET/$ _ POST [英] php $_GET/$_POST

问题描述

你好！
我的PHP有点问题-$ _GET/$ _ POST

首先，我有一个按钮:

Hello!
I have a little problem with PHP- $_GET/$_POST

First I have a button:

<form action=''index.php'' method=''post''>
<input type=''submit'' name=''show'' value=''Make a post!''>
</form>

然后在php中:

And then in php:

if ($_POST[''show''])
{
//echoing out another button with the name, submit

echo "<form action=''index.php'' method=''POST''>
<input type=''submit'' style=''width: 175px;'' name=''submit'' value=''post''>
</form>"; //and some text boxes!

然后...这会将我在某些文本框中(在这里没有写过)写的东西上传到mysql:

And then... This will upload the things that i wrote in some text boxes(which I didn''t write here) to mysql:

if ($_POST[''submit''])
{
$name = $_POST[''name''];
$email = $_POST[''email''];
$message = $_POST[''message''];
$date = date("Y-m-d");
$time = date("H:i:S");

 if ($name&&$email&&$message)
 {
 $querypost = mysql_query("INSERT INTO blog VALUES ('''',''$name'',''$email'',''$message'',''$date'',''$time'')");
  echo "Please wait... <meta http-equiv=''refresh'' content=''2''>";
 }
 else
  echo ''Please fill out all fields'';
}

但它不起作用，我找不到原因?！当我没有"if($(_ POST ["显示])"时，上载(以及其他所有内容)都可以正常工作.
谢谢！

But its not working, and i can''t find a reason to why?! The uploading (and everything else) is working when i don''t have the "if ($_POST[''show''])" .
Thank you!
