click submit in html and run php code
提问by Sandy Stokes
I am new to html & php and I appreciate your help. I am trying to accept user input into a webpage and then after the user clicks the submit button, write a new record out to MySQL. I am using Wordpress so the tags are not exactly textbook.
我是 html 和 php 的新手，感谢您的帮助。我试图接受用户对网页的输入，然后在用户单击提交按钮后，将新记录写入 MySQL。我正在使用 Wordpress，所以标签并不完全是教科书。
So my first problem is that the submit button does not appear to execute the php code. I also would appreciate it if someone could check how I am passing my html field names to the php variables to make sure that I am on the right track. Thanks for your help!
所以我的第一个问题是提交按钮似乎没有执行php代码。如果有人可以检查我如何将我的 html 字段名称传递给 php 变量以确保我在正确的轨道上，我也将不胜感激。谢谢你的帮助！
html code to collect user input for fields on the form.....
<?php>
if(isset($_POST['Submit'])) {
$FName = $_POST['FName'];
$MI = $_POST['MI'];
$LName = $_POST['LName'];
....
?>
<form action="" method="post">
<input type="submit" name="Submit" value="Submit">

I think it can be good to read a bit more about it. Check here.
我认为阅读更多关于它的信息会很好。检查这里。
Anyway, you need to say the name of the file to post to: <input type="submit" action="file.php" name="Submit" />for example.
无论如何，您需要说出要发布到的文件的名称：<input type="submit" action="file.php" name="Submit" />例如。
And you need to have more inputs than the submit.
并且您需要比提交更多的输入。
Acording to your php you should have as example this in the html:
根据您的 php，您应该在 html 中有这样的示例：
<form action="your_php_file.php" method="post">
<p>Your first name: <input type="text" name="FName" /></p>
<p>Your last name: <input type="text" name="LName" /></p>
<p>Your MI: <input type="text" name="MI" /></p>
<p><input type="submit" name="Submit"/></p>
</form>
And the php tags are like <?phpto open, and ?>to close.
而 php 标签就像<?php打开和?>关闭一样。
So like:
所以像：
<?php
if(isset($_POST['Submit'])) {
$FName = $_POST['FName'];
$MI = $_POST['MI'];
$LName = $_POST['LName'];
//....
?>

Your PHP tagsare incorrect. Use <?phpand ?>to tell PHP to start and stop interpreting the code between them. Also, make sure you're closing the formelement(I only see you're opening it) using </form>and that you indeed have all those fields contained inside of it.
您的PHP 标签不正确。使用<?php和?>告诉 PHP 开始和停止解释它们之间的代码。此外，请确保您正在关闭form元素（我只看到您正在打开它）使用</form>，并且您确实在其中包含所有这些字段。
