Telerik PHP剑道UI网格/外键列演示错误
在仔细地从我的TestPage.php(只是更改数据库连接)中编写代码并使用演示的文件DaraSourceResult.php之后,它仍然出现了两个错误: 1) 当网格呈现时,它从数据库中获取数据,但ForeignKey列为空 2) 如果在“外键”列中单击,它将成功显示数据库中的CategoryNames,但当您选择一个类别时,它不起作用,可能是因为它试图在数字字段中使用文本 我附上了一张照片,上面显示了上述每个bug。下面还有我在TestPage.php中使用的代码 你能帮我修复这两个错误吗 非常感谢Telerik PHP剑道UI网格/外键列演示错误,php,kendo-ui,telerik,Php,Kendo Ui,Telerik,在仔细地从我的TestPage.php(只是更改数据库连接)中编写代码并使用演示的文件DaraSourceResult.php之后,它仍然出现了两个错误: 1) 当网格呈现时,它从数据库中获取数据,但ForeignKey列为空 2) 如果在“外键”列中单击,它将成功显示数据库中的CategoryNames,但当您选择一个类别时,它不起作用,可能是因为它试图在数字字段中使用文本 我附上了一张照片,上面显示了上述每个bug。下面还有我在TestPage.php中使用的代码 你能帮我修复这两个错误吗
我发现了错误。我只是对变量中的列字段名称有问题。它没有使用FKCateriaEntrada,而是尝试使用FKCateria
代码现在运行顺利。如果需要,您可以使用它。我发现了错误。我只是对变量中的列字段名称有问题。它没有使用FKCateriaEntrada,而是尝试使用FKCateria 代码现在运行顺利。如果需要,你可以使用它
