小編給大家分享一下php+mysql開發(fā)題庫的示例分析,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!
具體如下:
題庫,對于教育機構(gòu),學(xué)校,在線教育,是很有必要的,網(wǎng)上也有不少的第三方在線題庫系統(tǒng),但是本次案例,會讓有需要的人了解題庫的開發(fā)思路,其實很簡單,無非就是一個表單驗證,數(shù)據(jù)庫驗證。
1、先構(gòu)建表單數(shù)據(jù)
2、把表單數(shù)據(jù)通過get或者post方式提交到表單驗證頁面,和數(shù)據(jù)庫進行匹配
3、返回結(jié)果,答案正確或者錯誤
構(gòu)建表單:
index.php
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=0" /> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <title>題庫</title> <style type="text/css"> *{list-style: none;margin:0px;padding: 0px;} #tiku{ width: 300px; margin:10px auto; } #tiku ul li{ float: left; } </style> </head> <body> <?php //獲取數(shù)據(jù)庫配置 require_once("config.php"); //連接數(shù)據(jù)庫 $con = mysql_connect($host,$username,$password); //設(shè)置數(shù)據(jù)庫字符集 mysql_query("SET NAMES UTF8"); //查詢數(shù)據(jù)庫 mysql_select_db($db, $con); //查詢數(shù)據(jù)庫 //獲取最新的1條數(shù)據(jù) $all = mysql_num_rows(mysql_query("select * from $tb")); //定義分頁所需的參數(shù) $lenght=1; //每頁顯示的數(shù)量 @$page=$_GET['page']?$_GET['page']:1; //當(dāng)前頁 $offset=($page-1)*$lenght; //每頁起始行編號 $allpage=ceil($all/$lenght); //所有的頁數(shù)-總數(shù)頁 $prepage=$page-1; //上一頁 if($page==1){ $prepage=1; //特殊的是當(dāng)前頁是1時上一頁就是1 } $nextpage=$page+1; if($page==$allpage){ $nextpage=$allpage; //特殊的是最后頁是總數(shù)頁時下一頁就是總數(shù)頁 } $sql="select * from $tb order by id ASC limit {$offset},{$lenght}"; $rest=mysql_query($sql); while($row = mysql_fetch_assoc($rest)) { $id = $row["id"]; $title = $row["title"]; $A = $row["answer_A"]; $B = $row["answer_B"]; $C = $row["answer_C"]; $D = $row["answer_D"]; $true = $row["true"]; $score = $row["score"]; } ?> <div id="tiku"> <form action="check.php" method="get"> <p><?php echo $title;?></p> <input type="radio" name="xuanxiang" value="<?php echo $A;?>">A:<?php echo $A;?><br> <input type="radio" name="xuanxiang" value="<?php echo $B;?>">B:<?php echo $B;?><br> <input type="radio" name="xuanxiang" value="<?php echo $C;?>">C:<?php echo $C;?><br> <input type="radio" name="xuanxiang" value="<?php echo $D;?>">D:<?php echo $D;?><br><br> <input type="hidden" name="id" value="<?php echo $id;?>"> <button>提交</button> </form> </div> <br/> <?php echo "<div id='tiku'>"; echo "<ul>"; echo "<li><a href='next.php?page=$prepage'>上一題</a></li>"; echo "<li><a href='next.php?page=$nextpage'>下一題</a></li>"; echo "</ul>"; echo "<div>"; echo "<br/>"; echo "<p class='fenye_tips'>共".$allpage."道題,當(dāng)前是第".$page."題</p>"; echo "<br/><br/>"; echo "</div>"; ?> </body> </html>
表單接收
check.php
<?php header("Content-type:text/html;charset=utf-8"); //獲取數(shù)據(jù)庫配置 require_once("config.php"); //連接數(shù)據(jù)庫 $con = mysql_connect($host,$username,$password); //設(shè)置數(shù)據(jù)庫字符集 mysql_query("SET NAMES UTF8"); //查詢數(shù)據(jù)庫 mysql_select_db($db, $con); //獲取數(shù)據(jù) $xuanxiang = $_GET["xuanxiang"]; $id = $_GET["id"]; if (empty($xuanxiang)) { echo "<script>alert('請選擇一個答案!');history.go(-1);</script>"; }else{ //查詢數(shù)據(jù)庫 $result = mysql_query("SELECT * FROM $tb WHERE id =".$id); while($row = mysql_fetch_array($result)) { $true = $row["true"]; $next_id = $id+1; if($xuanxiang == $true){ echo "<script>alert('正確!得5分!');location.href='next.php?page=$next_id';</script>"; }else{ echo "<script>alert('錯了!扣5分!');history.go(-1);</script>"; } } } ?>
數(shù)據(jù)庫配置
config.php
<?php //配置文件 - BY TANKING $host="數(shù)據(jù)庫地址"; $username="賬號"; $password="密碼"; $db="數(shù)據(jù)庫名"; $tb = "表名"; ?>
next.php
