#What should I do if php cannot transmit the form value?
Error code;
html页代码：
<form action="show.php" target="mainFrame" method="post">
<input type="text" name="words" cols="200"/><input type="submit" value="发言"/>
php页代码：
<?php require_once('config.php'); ?><?phpmysql_select_db("data");$words=$_post['words'];if($words){$query="insert into chat(chtime,nick,words,face)values(now(),'$nick','$words','$face')";//插入SQL语句mysql_query($query,$link_ID); //发送留言到数据库header("refresh:0; URL='show.php'"); }
?>Solution:
php is case-sensitive, use $_POST to check.
Another one, in the html part, the end character of the form cannot be seen.
<form method="post" action="show.php" enctype="application/x-www-form-urlencoded" name="form1" id="form1">
<input type="text" name="words" value="" />
<input type="submit" value="发言"/>
</form>
<?php
mysql_select_db("data");
$words = $_POST["words"];
if($words){
$query="insert into chat(chtime,nick,words,face)values(now(),'$nick','$words','$face')";//插入SQL语句
mysql_query($query,$link_ID); //发送留言到数据库
header("refresh:0; URL='show.php'"); }
?>Follow the above steps to improve it. If it still doesn’t work, add a print_r($_POST); in front of mysql_select_db("data"); to see what data can be output.
