單擊保存按鈕後更新數據庫

Question

我有一個動態表，可以內聯編輯或可以動態添加行。我希望能夠點擊保存按鈕來運行UPDATE查詢來更新數據庫。但我無法弄清楚如何。我真的堅持這一點，並會感謝任何幫助。

我的DB連接：

<?php 
$host="xxxxx"; 
$dbName="xxxxxxxx"; 
$dbUser="xxxx"; 
$dbPass="xxxxxxxxxxxxx"; 

$dbh = new PDO("sqlsrv:server=".$host."; Database=".$dbName, $dbUser, $dbPass); 
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
$sql = "SELECT * FROM Stage_Rebate_Master ORDER BY MR_ID ASC"; 
?> 

HTML/PHP：

<div id="users-contain" class="ui-widget"> 
<table id="html_master" class="ui-widget ui-widget-content"> 
<thead> 
    <tr class="ui-widget-header"> 
    <td>ID</td> 
    <td>Vendor</td> 
    <td>Buyer ID</td> 
    <td>POC Name</td> 
    <td>POC Email</td> 
    <td>POC Phone</td> 
    <td>Edit/Delete</td> 
    </tr> 
</thead> 
<tbody> 

<?php 
    foreach ($dbh->query($sql) as $rows){ 
    ?> 
    <tr> 
     <td class="mr_id" contenteditable="false"><?php echo intval ($rows['MR_ID'])?></td> 
     <td class="mr_name" contenteditable="false"><?php echo $rows['MR_Name']?></td> 
     <td class="buyer_id" contenteditable="false"><?php echo $rows['Buyer_ID']?></td> 
     <td class="poc_n" contenteditable="false"><?php echo $rows['MR_POC_N']?></td>  
     <td class="poc_e" contenteditable="false"><?php echo $rows['MR_POC_E']?></td> 
     <td class="poc_p" contenteditable="false"><?php echo $rows['MR_POC_P']?></td> 
     <td><input type="button" class="edit" name="edit" value="Edit"> 
     <input type="button" class="deactivate" name="deactivate" value="Deactivate"></td> 
    </tr> 
<?php 
    } 
?> 
</tbody> 

    <input type="button" class="create-user" value="Add Row"> 
    <input type="submit" value="Save Table" class="save"> 

</table> 
</div> 

    <input type="button" class="create-user" value="Add Row"> 
    <input type="submit" value="Save Table" class="save">

// ----- Save Table -----

    // ------ Confirmation box in order to deactivate/activate row ----- 
    if (confirm('Saving will update the entire table. Are you sure you want to save?')) { 
     // yourformelement.submit();

    } 
}); 

Answer 1

在您的保存按鈕點擊事件，寫下面的代碼：

// ----- Save Table ----- 
$(document).on("click", ".save", function() { 

    // ------ Confirmation box in order to deactivate/activate row ----- 
    if (confirm('Saving will update the entire table. Are you sure you want to save?')) { 
    var tabledata=[]; 
    $("#html_master tbody tr").each(function(index) { 
     tabledata[index] = { 
      mr_id: $(this).find("td.mr_id").text(), 
      mr_name: $(this).find("td.mr_name").text(), 
      buyer_id: $(this).find("td.buyer_id").text() //add rest of the fields 
     }; 

}); 
    //now call a normal ajax request to your php process page 

    $.ajax({ 
     url: "process.php", 
     type: "post", 
     data: {data: tabledata}, 
     success: function(result){ 
      //do whatever you want 
     } 
    }) 

     // yourformelement.submit(); 
    } else { 
     return false; 
    } 
}); 

在你的PHP程序頁面（我假設process.php），你現在可以檢索這些數據後和運行SQL查詢

$data = $_POST['data']; 
foreach($data as $row){ 
    // now you have $row['mr_id'], $row['mr_name'] etc. do normal sql update query in each loop. I suppose mr_id is the primary key. so use it in where clause 
} 

這是拯救這整個表一次使用AJAX的總體思路。還請注意，我沒有測試代碼。可能有錯誤。雖然有一些豐富的第三方腳本，看起來不錯，使它更容易使用。

與單獨保存所有可能變慢的行相比，我認爲最好單獨保存每一行，因爲單擊編輯每行時已經有一個保存按鈕。在這種情況下，代碼需要修改一下。

希望它會有所幫助。讓我知道是否需要澄清！
