Php Jquery表中未定义的索引/值
我在mysql中创建了一个列，并像这里一样设置了默认值，但当我尝试在额外的列上显示数据时，我的jquery flexigrid表中有一个未定义的值： 我想这是我的index.php post2.php代码中的一个错误-----------------index.php post2.phpPhp Jquery表中未定义的索引/值,php,jquery,mysql,Php,Jquery,Mysql,我在mysql中创建了一个列，并像这里一样设置了默认值，但当我尝试在额外的列上显示数据时，我的jquery flexigrid表中有一个未定义的值： 我想这是我的index.php post2.php代码中的一个错误-----------------index.php post2.php 我不知道是哪一个错误，我也不知道那一行是错误代码。不要手动创建json，这既耗时又容易出错 改用json_encode$array 您没有在php中为每一行添加额外的属性，因此表插件告诉您该字段未定义 通过在浏

通过在浏览器控制台的“网络”选项卡中将数据作为json进行检查，您也应该能够看到这一点。将代码粘贴到POST中，就像数据属性extra未定义一样。数据是什么样子的？现在粘贴的代码，问题是：如果我在mysql中插入charlietfl，值charlietfl出现在mysql表中，但在jquery表中，我显示未定义，我不明白为什么可以正确重新粘贴我的代码，请？我是代码新手，不太了解json php mysql机制。请尝试添加$json.=，'。addslashes$row['extra']；添加这段代码后，我的jquery表显示正在处理，请稍候，表中的所有值都将消失。看：。我在$json.=，'之后插入这段代码。addslashes$row['numcode'].]；例如，若我在更改列表中数据的位置之前插入，我会在mysql中为额外的列添加giga。而视图值是为编号代码设置的。但是加上这段代码，我把数据移到了错误的列中。有什么想法吗，charlietfl？
