Web表单交互

PHP与Web表单交互

1.Web表单交互—提交表单的方法

<form action = '../lishuaibo/dome.php' method = 'post'>
        <input type = 'text' name = 'user' value = 'woshi'/>
        <input type = 'password' name = 'pew' value = ''/>
</form>

action 值：跳转位置

属性：method = ' ' 值：post、get

post 比较安全

get 会暴露信息

2.获取POST方式提交的表单数据

 if (isset($_POST['user'])&&isset($_POST['pew'])) {
        echo $_POST['user'];    //输出结果:text
        echo '<br />';
        echo $_POST['pew'];     //输出结果:password
    }

3.数组方式提交数据—单选按钮

<input type = 'radio' name = 'equally' value = '男' checked/>男
<input type = 'radio' name = 'equally' value = '女'/>女
print_r($_POST['equally']);

4.数组方式提交数据—下拉菜单

<select name = "city">
    <option value = "济南">济南</option><option value = "天津">天津</option>
    <option value = "大连">大连</option><option value = "其他">其他</option>
</select>
print_r($_POST['city']);

5.数组方式提交数据—复选框

<input type = 'checkbox' name = 'equally' value = 'Apple'/>苹果
<input type = 'checkbox' name = 'equally' value = 'Pear'/>梨
<input type = 'checkbox' name = 'equally' value = 'orange'/>橘子
print_r($_POST['equally']);

6.提交

<input type = 'submit' value = '提交'/>
