发布到db时导致文本值为空的原因是什么

时间:2014-11-03 04:49:48

标签: php sql null

我附加了一个处理图像文件上传的表单和脚本。我添加了文本字段,单选按钮和其他文件上传。

脚本的图像上传和附加文件上传部分工作正常,单选按钮也是如此。这些值正在保存到我的sql db中。

但是,所有文本字段都是将空值提交到sql。

这里是我的SQL语句的脚本,它记得正在处理图像的URL,记录单选按钮的值。但是所有的文字字段都是' title'和'地址'在数据库中是空白的。

html表单

答案 0 :(得分:0)

如果你在CropAvatar类中执行mysql_code,那么你的变量就超出了类范围。你似乎没有显示你的整个PHP代码(缺少一些结束标记),因此我无法确定。
