1，表单的插入
表单的插入操作步骤如下：
a,在html的body>…/body>标记中添加一个表单
b,在表单中添加表单元素
具体示例代码如下：
<form name ="form1" method = "post" enctype ="multipart/form-data" action ="index.php"> <table width ="405" border ="1" cellpading ="1" cellspacing ="1" bordercolor ="#FFFFFF" bgcolor ="#999999"> <tr bgcolor ="FFCC33"> <td width ="103" height ="25" align ="right"> 姓名：</td> <td width ="144" height ="25"> <input name ="user" type ="text" id ="user" size ="20" maxlength ="100"> </td> </tr> <tr bgcolor ="#FFCC33"> <td width ="103" height ="25" align ="right">性别：</td> <td height ="25" colspan ="2" align ="left"> <input name ="sex" type ="radio" value ="男" checked>男 <input name ="sex" type ="radio" value ="女">女 </td> </tr> <tr bgcolor ="#FFCC33"> <td width ="103" height ="25" align ="right">密码：</td> <td width ="289" height ="25" colspan ="2" align ="left"> <input name ="pwd" type ="password" id ="pwd" size ="20" maxlength ="100"> </td> </tr> <tr bgcolor ="#FFCC33"> <td height = "25" align ="right">爱好：</td> <td height ="25" colspan ="2" align ="left"> <input name ="fond[]" type ="checkbox" id = "fond[]" value ="音乐">音乐 <input name ="fond[]" type ="checkbox" id ="fond[]" value ="其他">其他 </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" align ="right">写真</td> <td height ="25" colspan ="2"> <input name ="phpto" type ="file" size ="20" maxlength ="1000" id ="photo"> </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" align ="right">个人简介：</td> <td height ="25" colspan ="2"> <textarea name ="intro" cols ="28" rows ="4" id ="intro"></textarea> </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" colspan ="3"> <input name ="submit" type ="submit" value ="提交"> <input name ="submit2" type ="reset" value ="重置"> </td> </tr> </table></form>
运行结果如下：
2，表单的获取
(1) 使用POST方法提交表单
应用POST方法时，只需要将form>中表单的method属性设置为POST即可。
示例代码如下：
user.html文件代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" lang="en_US" xml:lang="en_US"><!-- * Created on 2015年3月24日 * * To change the template for this generated file go to * Window - Preferences - PHPeclipse - PHP - Code Templates --> <head> <title> </title> </head> <body> <form name ="form1" method ="post" enctype ="multipart/form-data" action ="index.php"> <table width ="300" border ="0" cellpading ="0" cellspacing ="0"> <tr> <td height ="30" align ="right">姓名：</td> <td height ="30"> <input name ="userName" type ="text" size ="20"> <input name ="submit" type ="submit" value ="提交"> </td> </tr> </table></form> </body></html>
index.php的代码如下：
<?php include("user.html"); $userName =$_POST["userName"]; echo $userName; ?> 运行结果如下：
可以看到表单上的数据已经通过post方法传递给了服务器。
(2)使用GET方法提交表单
GET方法是提交表单方法的默认方法，使用GET提交的参数会附加到url地址的后面，具体格式如下：
在这里user.html文件还是用上面的，把form的method属性改为get就好了。
index.php的代码如下：
<?php include("user.html"); $userName =$_GET["userName"]; echo $userName; ?> 运行结果如下：
可以看到参数已经被附加到url的后面了。
