php - 按具有相似信息的 2 列分组以链接到第二个表

Question

我有两列包含类似信息:

第 1 列 = 项目 1、项目 3、项目 5 第 3 列 = 第 3 项、第 5 项、第 8 项

我想显示两列中每项的总数。

我有这个:

<小时/>

$sql = mysql_query("SELECT FirstTypeID, SecondTypeID, ThirdTypeID, DesignID, COUNT(DesignID) FROM designs WHERE Approved = '1' GROUP BY FirstTypeID, SecondTypeID, ThirdTypeID");
while ($row = mysql_fetch_array($sql)) {
    $DesignID = stripslashes($row['DesignID']);
    $FirstTypeID = stripslashes($row['FirstTypeID']);
    $SecondTypeID = stripslashes($row['SecondTypeID']);
    $ThirdTypeID = stripslashes($row['ThirdTypeID']);
    $Total = stripslashes($row['COUNT(DesignID)']);
}

$result2 = mysql_query("SELECT * FROM types WHERE TypeID = '$FirstTypeID' OR TypeID = '$SecondTypeID' OR TypeID = '$ThirdTypeID'");
while ($row2 = mysql_fetch_array($result2)) {
    echo "<li><a href='index_type.php?TypeID=".$row2{'TypeID'}."'>".$row2{'TypeName'}." (" . $Total . ")</a></li>";
}

<小时/>

但我没有得到我想要的结果，它只给了我一列的结果。

我不确定这是否是您所要求的，但就是这样

$typesIDs = array(type0 => "", type1 => "", type2 => ""...);

foreach($typesID as $index=>$value){
   $query = "SELECT COUNT(*) AS total FROM designs COLUMN1 = ".$index." OR COLUMN2 = ".$index;
   $sql = mysql_query($query);
   $row = mysql_fetch_array($sql);
   array[$index] => $row["total"]
}
