PHP表单验证(不知道如何将其拆分为两个不同的页面)
我正在用PHP编写一个联系人表单。我对PHP的了解几乎不存在 我已经尝试了一段时间,让一个HTML表单提交到PHP表单,以验证其文本字段,如果为空,则为必填字段,但无法使任何内容正常工作。我也不知道AJAX,否则的话,我会尝试这样做 因此,我们求助于在HTML页面中使用PHP自身表单 这是当前版本:PHP表单验证(不知道如何将其拆分为两个不同的页面),php,html,ajax,forms,Php,Html,Ajax,Forms,我正在用PHP编写一个联系人表单。我对PHP的了解几乎不存在 我已经尝试了一段时间,让一个HTML表单提交到PHP表单,以验证其文本字段,如果为空,则为必填字段,但无法使任何内容正常工作。我也不知道AJAX,否则的话,我会尝试这样做 因此,我们求助于在HTML页面中使用PHP自身表单 这是当前版本: <?php // define variables and set to empty values $firstNameErr = $lastNameErr = $emailErr = $me

我已经在php内容的底部包括了这一点,即在函数测试输入之后。header('location:php\u mailer\u form.php')代码>它的位置正确吗
但由于某种原因,当我试图访问contact.php表单时,它甚至没有显示出来,而是直接转到php_mailer_form.php底部的错误表单
if(!$mail->send()) {
header('location: url/contactError.html');
} else {
header('location: url/contactResult.html');
}
为什么??(如果我需要包括其他信息,请告诉我)

我不确定我是否完全理解您的意图,但通常最好将表单提交到同一页面,以便您可以报告经常发生的错误(就像您正在做的那样)。不过,您可以做的是,一旦您验证了凭据,设置一个会话变量“$\u session['userisloggedin']”,然后使用“header”将用户发送到您想要的页面(例如pageyoucanolyseeifloggedin.php),并在页面顶部显示php代码“if(!(isset($\u session['userisloggedin'])header(“location:“login.php”)若不允许将其发送回登录屏幕,请参阅page@AndrewB,你好,谢谢你的评论。嗯。关于会话,它与用户登录/注销完全无关。这与转到另一个php页面有关,因此我希望能够在会话模式下收集变量,因为我的理解是,这是能够将变量转到多个页面的唯一方法。@AndrewB,同样基于我上面发布的内容,您认为这是否可接受用于商业用途?请让我知道。你可以使用它,但你可以使用更多的验证。另外,您的表单会将$\u POST
属性发送到您的其他页面。嗯,我仍然不确定是否完全理解您的意图。如果要保存电子邮件,知道它是正确的,请设置变量$_SESSION['email']=$email$_会话['first-name']=$first\u-name;应该允许您保存会话的所有变量。在尝试使用或分配会话变量Oh wow之前,请记住调用“session_start();”。非常感谢。让我试试,我会给你回复的。我很感激!我有一个问题,我在上面的问题的附录2下发布了这个问题。非常感谢您的意见。谢谢。页眉用于更改页面。在html发送给用户之前,您正在更改页面。我不知道这个邮件程序是如何工作的,但我想你应该“包括”邮件程序文件,而不是更改到那个页面。i、 e.包括(“php_mailer_form.php”);这样做可以有效地从该文件中提取代码,并将其直接插入调用该文件的文件中。一旦它出现,您就可以使用它定义的任何函数/类。如果您使用header,下面的任何PHP代码都不会运行,因为您将看到这段代码并说“好的,我们需要转到另一个页面并运行它的代码,忘掉这段代码”好的。那么,如何将其发送到另一个php表单?好啊看,我有一个php_mailer_form.php,它处于会话模式,所以它应该从这个表单中收集它。但我如何才能做到这一点呢?我认为在这个自php表单中添加标题可以实现这一点。如果我有点慢,请原谅。
