本文实例讲述了PHP实现从PostgreSQL数据库检索数据分页显示及根据条件查找数据。分享给大家供大家参考，具体如下：
主要功能是从postgreSql查询数据，并检索，由于自己刚开始接触，所以难点在于多条数据同时筛选并分页显示出来，写下自己的代码与大家共享。
<html><head><script type="text/javascript"> /** * 分页函数 * pno--页数 * psize--每页显示记录数 * 分页部分是从真实数据行开始，因而存在加减某个常数，以确定真正的记录数 * 纯js分页实质是数据行全部加载，通过是否显示属性完成分页功能 **/function goPage(pno,psize){ var itable = document.getElementById("idData"); var num = itable.rows.length;//表格所有行数(所有记录数) console.log(num); var totalPage = 0;//总页数 var pageSize = psize;//每页显示行数 //总共分几页 if(num/pageSize > parseInt(num/pageSize)){ totalPage=parseInt(num/pageSize)+1; }else{ totalPage=parseInt(num/pageSize); } var currentPage = pno;//当前页数 var startRow = (currentPage - 1) * pageSize+1;//开始显示的行 31 var endRow = currentPage * pageSize;//结束显示的行 40 endRow = (endRow > num)? num : endRow; 40 console.log(endRow); //遍历显示数据实现分页 for(var i=1;i<(num+1);i++){ var irow = itable.rows[i-1]; if(i>=startRow && i<=endRow){ irow.style.display = "block"; }else{ irow.style.display = "none"; } } var pageEnd = document.getElementById("pageEnd"); var tempStr = "共"+num+"条记录 分"+totalPage+"页 当前第"+currentPage+"页"; if(currentPage>1){ tempStr += "<a href=/"#/" onClick=/"goPage("+(1)+","+psize+")/">首页</a>"; tempStr += "<a href=/"#/" onClick=/"goPage("+(currentPage-1)+","+psize+")/"><上一页</a>" }else{ tempStr += "首页"; tempStr += "<上一页"; } if(currentPage<totalPage){ tempStr += "<a href=/"#/" onClick=/"goPage("+(currentPage+1)+","+psize+")/">下一页></a>"; tempStr += "<a href=/"#/" onClick=/"goPage("+(totalPage)+","+psize+")/">尾页</a>"; }else{ tempStr += "下一页>"; tempStr += "尾页"; } document.getElementById("barcon").innerHTML = tempStr;}</script> <style type="text/css"> table { text-align:center; width:1000px; } th { width:100px; } input { width:100px; } td { width:100px; } </style> </head> <body onLoad="goPage(1,10);"> <form method="post" action="browes.php"> <table border="1"> <tr> <th><h2>个人概况一览</h2></th> </tr> <tr> <table border="1" > <tr> <td>姓：</td> <td><input type="text" name="surname"> </td> <td>名：</td> <td><input type="text" name="name"> </td> <td>手机:</td> <td><input type="text" name="phone"> </td> <td>性别：</td> <td><select name="sex" id="select_k1" class="xla_k"> <option value=""> </option> <option value="male">男</option> <option value="female">女</option> </select> </td> <td>学校:</td> <td><input type="text" name="school"> </td> </tr> </table> </tr> <tr> <td><input type="submit" name="submit" value="提交"> </td> <td><input name=reset type=reset value=重置></td> </tr> </table> </form></body><body> <table id="idData" border="1" > <tr> <th>照片</th> <th>姓名</th> <th>性别</th> <th>生日</th> <th>邮箱</th> <th>电话</th> <th>学校</th> <th>技能</th> <th>选项</th> </tr> <?php include "../head.php"; $s = $_POST["surname"]; $a = $_POST["name"]; $b = $_POST["phone"]; $c = $_POST["sex"]; $d = $_POST["school"];/*下面这段代码是PostgreSQL数据库多条数据检索编写数据库的通用方法*/ $field = "where 1 = 1 "; if($a){ //magic_quotes_gpc=on,addslashes not used. $name = str_replace('/'', "''", $a); $field.= "and (name like '%".$name."%') "; } if(($s)!=NULL){ $surname = str_replace('/'', "''", $s); $field.= "and (surname like '%".$surname."%') "; } if(($c)!=NULL){ $field.= "and (sex = '".$c."')
