PHP development corporate website tutorial: Add contact us information
First we look at the html code of the following add page:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>添加公司信息</title>
<style type="text/css">
.ipt{width:180px;height:30px;border-radius:5px;
outline:none;border:1px solid #eee;box-sizing:border-box;padding-left:15px;}
.txt{width:250px;height:200px;}
.sub{width:50px;height:20px;border:1px solid #eee;background:#eee;color:#ff7575;}
</style>
</head>
<body>
<form method="post" action="addcontact.php">
公司地址:<input type="text" name="site" class="ipt"></br></br>
公司电话:<input type="text" name="tel" class="ipt"></br></br>
技术支持:<input type="text" name="suppot" class="ipt"></br></br>
售后电话:<input type="text" name="nexttel" class="ipt"></br></br>
公司传真:<input type="text" name="fax" class="ipt"></br></br>
公司主页:<input type="text" name="home" class="ipt"></br></br>
电子邮件:<input type="text" name="email" class="ipt"></br></br>
<input type="submit" value="添加" class="sub">
</form>
</body>
</html>Looking at the above code, the form is submitted to the addcontact.php file, which receives the parameters submitted by the form, and then adds it to the database according to the sql statement
Let’s take a look at the addcontact.php part of the code:
<?php
//添加联系我们信息部分代码
require_once('conn.php');
$site = $_POST['site']; //地址
$tel = $_POST['tel']; //电话
$suppot = $_POST['suppot'];//技术支持
$nexttel = $_POST['nexttel'];//售后电话
$fax = $_POST['fax']; //公司传真
$home = $_POST['home']; //公司首页
$email = $_POST['email']; //电子邮件
if(empty($site)){
echo "<script>alert('请填写地址');history.go(-1);</script>";
}else if(empty($tel)){
echo "<script>alert('请填写电话');history.go(-1);</script>";
}else if(empty($suppot)){
echo "<script>alert('请填写技术支持');history.go(-1);</script>";
}else if(empty($nexttel)){
echo "<script>alert('请填写售后电话');history.go(-1);</script>";
}else if(empty($fax)){
echo "<script>alert('请填写公司传真');history.go(-1);</script>";
}else if(empty($home)){
echo "<script>alert('请填写公司首页');history.go(-1);</script>";
}else if(empty($email)){
echo "<script>alert('请填写电子邮件');history.go(-1);</script>";
}else{
$sql = "insert into `contact`(site,tel,suppot,nexttel,fax,home,email) values('$site','$tel','$suppot','$nexttel','$fax','$home','$email')";
$res = mysql_query($sql);
if($res){
echo "<script>alert('添加公司信息成功');location.href='contact.php';</script>";
}else{
echo "<script>alert('添加公司信息失败');history.go(-1);</script>";
}
}
?>As shown in the above code, we have made a simple verification for the form information. It cannot be empty. When it is empty and submitted, it will Give prompt information
