显示所有带有 php 内连接的帖子

Question

所以我有这样一个项目，把帖子分成几个省。我可以显示帖子，但如果有 2 个或更多帖子，则只能显示 1 个，它只会显示 1 个帖子。这是我的 PHP 代码

<?php $p3=1;$posts=mysql_query("select * from provinces INNER JOIN posts ON posts.id_province=provinces.id_province");
                            while($ps3=mysql_fetch_array($posts)){
                                    $jdlpost=$ps3[nm_news];
                                    $despost=$ps3[desc];
                                    $jdlprovince=$ps3[nm_province];
                                                $link3=$_COOKIE[linkmenu].$ps3['id_news']."/"."news/".linktitle($ps3['nm_news']);
                                if($p3===1){
echo   "<div class=modal fade in' id='tc$ps3[id_news]> <div class=modal-dialog modal-lg> <div class='modal-content' style= 'margin-top: 100px;'>"
."<div class='modal-header'>"
                                    ."<h5 class='modal-title' id='exampleModalLabel'>$jdlprovince</h5>

                                        $(this).addClass("active");
                                        $(".tampil<?php echo $ps3['id_news'];?>").addClass("active");
                                    });
                                });
                            </script><?php
                            $p3++;
                        }
                        ?>

我不知道如何在我的代码中检索超过 1 篇具有相同 id_province 的帖子。因此，如果有 2 个具有相同 id_province 的帖子，我会再次重复，这样它就会像我的第一张图片一样检索。谢谢

感谢大家的帮助。

Answer 1

首先我建议你使用mysqli_query()，因为 MySQL 功能已经被弃用了。

根据您的代码，您需要将查询分成两部分

1) 从第一个表中获取数据

2) 根据id从第二张表中获取数据

现在根据结果，您可以根据需要显示 div。

$posts=mysql_query("select * from provinces");


while($ps3=mysql_fetch_array($posts)){
        while($result=mysql_fetch_array(mysql_query('select * from table2 where id ='.$ps3['id']))){
            // do code here
          }
 }
