我从互联网上获得了这个php电子邮件表单代码。
它适用于文本输入字段，但不适用于数字。
我已经尝试将表单上的所有输入类型都放到文本中，我在所有字段中输入错误信息。
所以我将数字字段的输入类型更改为数字和电话等 - 如果我提交数字，仍然会出错。电话号码。
但如果我用文本aaaaaa或gsdsjdaj等进行测试，它就有效。
为什么您认为我的表单将数字视为错误？
我已将所有字段的输入类型保留为文本。
但我确实尝试将它们更改为日期，电话，号码等，但这并没有奏效。
提前致谢。
这是我的代码：

答案 0 :(得分：0)
你执行这一行：在每个输入的
输入(!preg_match($string_exp,$[INPUT])
如果你查看用于此测试的正则表达式变量$string_exp，它只允许使用字母："/^[A-Za-z .'-]+$/"（a到z，大写或否，空格和破折号）
对于每个输入，数字更改为if(!preg_match($string_exp,$school_year))到if(!is_numeric($school_year))，它应该可以解决问题
