我有一个动态表，可以内联编辑，也可以动态添加行。我希望能够点击运行UPDATE查询的保存按钮来更新数据库。但我无法弄清楚如何。我真的很坚持这一点，并希望得到任何帮助。
我的数据库连接：
<?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">

</div>
<input type="button" class="create-user" value="Add Row">

答案 0 :(得分：0)
在保存按钮单击事件中，请编写以下代码：
// ----- 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进程页面（我假设是process.php），你现在可以检索这些发布数据并运行sql查询
$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
}
这是使用ajax一次保存整个表的一般想法。另请注意，我没有测试代码。可能有错误。虽然有一些丰富的第三方脚本看起来不错，但更容易使用。
我认为最好单独保存每一行，而不是将所有行保存在一起，因为当您单击编辑每一行时，已存在一个保存按钮。在这种情况下，代码需要稍微修改一下。
希望它会有所帮助。如果需要任何澄清，请告诉我！
