[英]“Cannot POST /send_form_email.php error” on contact form
I'm getting a "Cannot POST /send_form_email.php" error and have not figured out why? 我收到“无法发布/send_form_email.php”错误,还没有弄清楚为什么? The files are in the same directory.
这些文件位于同一目录中。 These are the only two HTML or PHP files on the site.
这是该网站上仅有的两个HTML或PHP文件。
<form id="contactform" action="send_form_email.php" method="post">
<div class="form-group">
<label for="firstname">First Name</label>
<input type="text" class="form-control placeholder="First Name" required>
</div>
<div class="form-group">
<label for="lastname">Last Name</label>
<input type="text" class="form-control" placeholder="Last Name" required>
</div>
<div class="form-group">
<label for="email">Email</label>
<input type="text" class="form-control" placeholder="Email" required>
</div>
<div class="form-group">
<label for="subject">Phone</label>
<input type="text" class="form-control" placeholder="Phone" required>
</div>
<div class="form-group">
<label for="message">Message</label>
<textarea id="message" rows="3" class="form-control"></textarea>
</div>
</div>
<div class="modal-footer">
<button class="btn btn-secondary" data-dismiss="modal">Cancel</button>
<button name="submit" type="submit" class="btn btn-primary" id="contact-submit">Submit</button>
</div>
</form>
Here is the PHP file that it is linked to. 这是链接到的PHP文件。 I have double checked the file names.
我仔细检查了文件名。 and I have cleared cache to make sure the changes took.
并且我已清除缓存以确保所做的更改。

Your PHP code never gets executed, $_POST['email'] does not exist. 您的PHP代码永远不会执行,$ _ POST ['email']不存在。 In fact in your form you have absolutely no 'name=' attributes - these are essential if you want to pick up anything from the form in the $_POST array.
实际上,在您的表单中,您绝对没有'name ='属性-如果您想从$ _POST数组的表单中获取任何内容,这些属性必不可少。
Eg for an input element like e-mail, you'd specify name='email' : 例如,对于像电子邮件这样的输入元素,您可以指定name ='email':
<input type="email" name='email' class="form-control" placeholder="Email" required>
$_POST['email'] will now (when submitted...) hold the e-mail address.
Notice the type='email' it will automatically (if browser supports the type, otherwise it reverts to text) check if e-mail address is valid 'pattern'. 请注意,type ='email'会自动(如果浏览器支持该类型,否则将还原为文本)检查电子邮件地址是否为有效的“模式”。 If you need the email address to be restricted more than just a string that looks like an email address you can use the pattern attribute - allows you to specify a regular expression the value must match for the value to be valid.
如果您不仅需要限制电子邮件地址,而不仅仅是看起来像电子邮件地址的字符串,则可以使用pattern属性-允许您指定正则表达式,该值必须匹配,该值才有效。
So I'd suggest you first check if the form was submitted with if(isset($_POST['submit'])) { rest of your code where you can fetch/handle values in $_POST array} 因此,建议您首先检查是否使用if(isset($ _ POST ['submit'])))提交表单{您的其余代码可在其中获取/处理$ _POST数组中的值}
