WordPress自定义页面提交表单

Question

I'm trying to write a simple script to write some data to mysql then read it. My code is working without a problem alone but I'm trying to use it inside a WordPress page, this is the point problem starts.

I have created a template file for WordPress, and using this template to create the page. Page shows up without a problem but whenever I try to submit the form inside it (my custom php form) it forwards me to index.php .

<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
<span>Enter Your Code : </span><br/>
<input type="text" name="sha256"><br/>
<p align = right><input type="submit" name="shaSubmit" value="Submit" /></p>
</form>

this is my form (inside custom php), and as you can see it posts the data to itself. At the the start of my custom php code I have

if(isset($_POST['Submit']))

But it doesn't matter, as soon as I click on button, it forward me to domain.com/index.php

Btw, this custom php is on a page with such url domain.com/custompage/

How can make this form work ?

ps. Code above is for reading from mysql.

Answer 1

You need to change 2 things.

(1)make action=""

don't need to use action=" echo htmlspecialchars($_SERVER["PHP_SELF"])"

(2)if(isset($_POST['shaSubmit'])){

the code ....

}
