Modal不会触发我的PHP验证。 我无法使用我的模式来使用PHP验证。 HTML验证有效。它连接到数据库并进行更新，但是跳过服务器端验证。我将不胜感激，这对我来说是新的，为什么模态无法验证。
我的PHP和Modal格式在一个文件中。我知道我需要在表单中添加更多错误消息，但是不填写电话号码和名字不会触发任何错误消息，因此一旦解决此问题，我将添加更多错误消息。该代码仅执行并更改数据库。

答案 0 :(得分：0)
这里有几个问题
您正在将$ error设置为布尔值，试图用布尔值定义数组键不起作用，如果$ error的值继续为布尔值[Edit]在为其分配数组键=>值之前计算为false，它将转换为数组，但是如果计算为true，则将生成Warning: Cannot use a scalar value as an array并继续为布尔值
您永远不会检查$ error来阻止脚本执行和更新数据库
