我想知道是否有人知道为什么我在我的脚本上出现此错误。我已经在这个脚本上工作了一段时间，并清理到了这一点。当从 pipeno 下拉列表中选择一个项目时，我只需要让表单上的一些字段自动填充，在这种情况下，下拉列表是触发器。到目前为止，我刚刚收到这两个错误，这似乎是阻碍脚本自动填充所需字段的原因。感谢您的贡献
这是错误
错误信息是
警告：pg_query()：查询失败：错误：在“，”或附近出现语法错误 第 9 行：...T wthick = 9.80, pipeno=837913,heatno1=56,pipeno2=,heatno2=6... ^ in C :\Users\iegbulefu\Documents\My Web Sites\Personal Site1\dropdown3.php 在第 32 行
这是我的脚本
