我在我的数据库中有逗号分隔列。该列称为“访问”,它处理数字如1,2,3,4,5,6,7。我需要比较会话的值的要求称为kt_department,其中一个逗号分隔值,例如kt_department的值为4,然后其余数据将显示在页面中。但是,如果不是,它将继续到下一行,但如果再次找不到,它应该继续到下一行,直到它发现逗号分隔的值。但是如果他们什么都没有发现,将会出现如“无可用记录”的消息。而且找到的记录应该是数字。如何查找session var是否在逗号分隔的列中?
我试图让我自己;
<?php
$news_connect = mysqli_connect("localhost","root","pwd", "dbase");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$kt_dept = $_SESSION['kt_department'] . " ";
$accessrights = explode(',', $row_news['accessrights']);
$news_query = "SELECT * FROM memo
WHERE (access LIKE '%{$accessrights}%' AND status='1' AND idcategory='1')";
$news_result = mysqli_query($news_connect, $news_query);
$row_news = mysqli_fetch_array($news_result);
echo $kt_dept;
?>
<div style="margin-top:30px;">
<table width="98%" border="0" cellspacing="5" cellpadding="0" class="curveborderboxnobg">

<td height="70" colspan="2" class="brandtitle" style="padding-left:20px;line-height:60px; font-size:18px;"><img src="images/icons/news-announcement.png" width="20" height="20" style="margin-right:10px;"><strong>News and Announcement </strong></td>

谢谢你们。请帮帮我。谢谢!
正常化您的数据库并摆脱逗号分隔第一http://stackoverflow.com/questions/3653462/is-storing-a-delimited-list-in-a-database-column-really-that-bad –
你可以尝试'$ news_query =“SELECT * FROM备忘录WHERE(访问IN'%{$ accessrights}%'AND status ='1'AND idcategory ='1')”;' – dcclassics
