最佳解答

參考這篇的寫法
範例是 AND，你自己改成 OR 即可

你在$result = $project->query($product);之前
加一列echo $product;把 SQL 指令顯示出來
就會知道是什麼原因了

目前的狀況是:我打某幾個格子他可以判斷並且抓出準確值，打另外一些格子會跑不出來，又打另外幾個格子會全部都跑出來

整個畫面和程式碼 只做一件事
就是組成要拿去查詢用的 SQL 指令

你要自己去看最後的結果 SQL 指令
才能判斷是什麼原因

判斷有沒有值，有值的話，組SQL語法。

$sqlStr = "select  *  from a4 where 1=1"
if($Month!=''){
    $sqlWhere +=  " And Month = '$Month' "
}

$product =  $sqlStr + $sqlWhere

大概程式碼長這樣，PHP語法不太會，請見諒。

我的媽耶!!看到很頭痛。
教你最簡單的組合方式。

首先，條件是你帶進來的 name 也就是資料庫的 name。
畢竟要簡單化。


$keyName = ['Month','Week','Dai','PLANT'];//後面的我懶的打，意思意思一下，反正就是所有要讀的欄位KEY都打上去。這是為了基本安全性。

$orWhere = [];
foreach($keyName AS $_key){
    if(isset($_POST[$_key]) && $_POST[$_key]){
        orWhere[] = $_key."='{$_POST[$_key]}'";
        //如果可以，$_POST[$_key]的值最好做一下拖位處理。這就保留給你自已想
    }
}
$sql = "SELECT * FROM db";
if($orWhere){
    $sql .= ' WHERE '.implode(' OR ',$orWhere);
}
echo $sql;//看一下組合

以上是單純的處理方式，但並不是很安全就是了。要注入還是有可能的。

感謝您的回答，我學起來了，謝謝指教。
另外，請問有推薦學MySQL與php語法的書嗎
