在php MySQL WHERE子句中使用數組復選框值
[英]use arrayed checkbox values in php MySQL WHERE clause
問題描述
我正在嘗試通過ajax將7個jquery復選框的值發送到php。 我試圖將值放在數組中並在ajax中序列化該數組。 最終，我想將復選框的值用作MySQL WHERE子句中的條件。 我的ajax成功完成，但是我不確定如何將值從php變量中提取出來並在MySQL SELECT語句的WHERE子句中使用它們。
謝謝！！！

我的Ajax代碼：

注意：我還包括了另一個ajax調用，分別是Revenueto和Revenuefrom date。 這次呼叫成功，並且我的表格根據這些日期正確顯示。 我只是無法從日期所在的同一頁面上獲取所選復選框的所有實際值。
一旦獲得這些值，我還將在WHERE語句中提出有關正確使用它們的任何建議。 每個復選框的值都與一個值選項invoices.stagestatus相匹配。
謝謝！

您可以通過ajax請求傳遞數組。 初始化為一個空數組，然后將每個選定復選框的值推入該數組（我已注釋了您的代碼以顯示在哪里進行更改）：
//send Revenue Data values to php using ajax.
//var revenuechbxarray = j('.revenuechbxs:checked').val();
var revenuechbxarray = [];
j('.revenuechbxs:checked').each(function(){
revenuechbxarray.push(j(this).val());
});
我不知道是否有最優雅的方法。
提交時，您會看到以下內容：
Array ( [0] => Prestage [1] => Validation [2] => Scheduling )
請注意，未選中的元素不會發布。
在PHP方面，要檢查是否發布了復選框，請檢查其值是否在數組中：
if (in_array('Prestage', $revenue_check)){
// your stuff here
}

編輯：您還可以在下面查看@rdimouro自己的答案，他在此顯示其完整的現在可用的版本。
如您所料，在當前代碼中， 只有第一個復選框值會添加到傳遞給Ajax的數據中。
要簡單地掌握整個表單數據，您只能使用$('form').serialize() ，如以下代碼片段所示：
$(document).ready(function() { console.log($('form').serialize()); });
label, button { display: block; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Prestage" checked> Prestage </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Validation" checked> Validation </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Scheduling"> Scheduling </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Production" checked>Production </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Needs BOL">Needs BOL </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Shipped: Acctg. To Close Out">Shipped: Account to Close </label> <label> <input type="checkbox" name="revenue_checkboxes[]" value="Complete">Moved to Complete for Selected Period </label> <label> Other data <input type="text" name="other-data" value="Some other data"> </label> </form>
您會看到，使用此獨特的語句，您可以獲得所有數據的相當完整的集合，因此您可以在Ajax調用中使用它，僅此而已：
j("#create_submit").click(function(){
//send Revenue Data values to php using ajax.
j.ajax ({
method: 'POST',
url: "revenue_report.php",
data: j('#yourFormId').serialize(),
success: function( response ) {
j('#fieldset_ReportDiv').html(response);
}
});
return false;
});
因此，在PHP中，您收到的$_POST項與表單中存在的不同name一樣多。 因此， $_POST['revenue_checkboxes']將是一個數組（ 僅包含選中的值 ）。
順便說一句，請注意：在當前的PHP代碼中，您正在尋找$_POST['revenuechbx'] ，這是正確的，因為這是您在Ajax調用的data{}參數中直接命名的方式。 但是使用上面的代碼，您將獲得HTML name屬性 。
現在，關於如何使用WHERE子句中的復選框值，您的問題尚不清楚，無法完全確定。
但是，如果invoices中的stagestatus列的可能值直接是HTML <input>被引用為value屬性的value ，那么這很簡單：
$sql = '
SELECT invoices.id, invoices.orderdate, invoices.stagestatus, ...
FROM clients
INNER JOIN invoices ON clients.id = invoices.clientid
INNER JOIN lineitems ON invoices.id = lineitems.invoiceid
WHERE invoices.orderdate BETWEEN '".$revenuefrom."' AND '".$revenueto."'
AND invoices stagestatus IN (' .
implode(',', array_map(function($item) {
return '"' . $item . '"';
}, $revenue_check)) . '
)
ORDER BY invoices.id DESC
';
在上方，我們使用array_map()將引號引起來，然后將implode()獲得以逗號分隔的列表，從而填充SQL IN()子句。
這樣，將僅選擇具有已檢查狀態之一的發票。
