Get Input Value on the same page with PHP?

Well, first i'm new in PHP. Is there a way to get the input value from a existing input on the page on page load with php and pass it to a variable?

For example i have this input: <input type="text" name="g_id_p" id="example1" value"foo">

I want to do something like this: $got_it = $_GET['g_id_p'];

Sorry again if i wrote my code wrong, im noobie on this. Hope to someone help me.

You can't really get an associated value of an input tag within the same PHP page but what you can do is set the value of a variable beforehand.

What I mean is, create an array that will store all the values of all the input tags.

$inputValues = array();
$inputValues['g_id_p'] = 'foo';

Then when you have the tag later on just echo it from the PHP var.

<input type="text" name="g_id_p" id="example1" value="<?php echo $inputValues['g_id_p']; ?>">

As you can see, we aren't really 'getting' the value that you set but the end result is the same.

First, would be great to know what method is the form. (GET or POST)

Then after know what type of method you could call it in PHP:

METHOD POST:

<input type="text" name="g_id_p" id="example1" value"foo">

$variable = $_POST['g_id_p'];

METHOD GET:

<input type="text" name="g_id_p" id="example1" value"foo">

$variable = $_GET['g_id_p'];

If you haven't defined a method, in html the tag for a form is:

    <form>
<!-- Here goes your input and some stuff -->
    </form>

Then it would be something like:

    <form name="form_name" class="form_class" id="form_id" method="TheFormMethod" action="ThePageThatExecutesThisForm">
<!-- Here goes your input and some stuff -->
    </form>

TheFormMethod can be post, get, delete, put.

You have to check if the values is set isset(), where you want to use the variable do:

if(isset($_GET['g_id_p'])){
   //your code
}
