php简单的form表单post传值

1、首先建立form.php文件和chuanzhi.php文件

3、<?php//当传过来的值小于两个字符或者大于10个字符出现错误警告！//echo isset($_POST['send']);if(isset($_POST['send'])){ if(strlen($_POST['username'])>2&&strlen($_POST['username'])<10){ echo '姓名：'.$_POST['username']; }else{ echo"<script>alert('姓名不能小于两位');history.back();</script>"; } echo '<br />'

5、<?php//echo isset($_POST['send']);if(isset($_POST['send'])){ if(strlen($_POST['username'])>2&&strlen($_POST['username'])<10){ echo '姓名：'.$_POST['username']; }else{ echo"<script>alert('姓名不能小于两位');history.back();</script>"; } echo '<br />'; if(isset($_POST['Sex'])){ echo '性别：'.$_POST['Sex']; }else{ echo"<script>alert('性别不能为空');history.back();</script>"; } echo '<br />';if(isset($_POST['diyi'])||isset($_POST['dier'])||isset($_POST['disan'])||isset($_POST['disi'])){echo '爱好：'; if(isset($_POST['diyi'])){ echo $_POST['diyi'].' '; } if(isset($_POST['dier'])){ echo $_POST['dier'].' '; } if(isset($_POST['disan'])){ echo $_POST['disan'].' '; } if(isset($_POST['disi'])){ echo $_POST['disi']; }}else{echo"<script>alert('爱好不能为空');history.back();</script>";} echo '<br />'; if(isset($_POST['cars'])){ echo '去过的地方：'.$_POST['cars'];}else{echo"<script>alert('选项不能为空');history.back();</script>";} echo '<br />'; if(strlen($_POST['text'])>10&&strlen($_POST['text'])<200){ echo '简历：'.$_POST['text'];}else{echo"<script>alert('简历不能小于10位');history.back();</script>";}}?>//当验证全部成功时便会显示出所有数据
