Applying ID to Function

[rbrown]

Hi All,

Apologies, but I am a bit stuck with getting a form button and action to work separately on each line of my PHP loop.

Currently the first button works, but if you decide to click a button on another line the first field is populated and not on the line of the button pressed.

As I understand it I would probably have to apply another numbered ID to the ID of the element i have already applied. But am a bit stuck on how to. (been trying for day and a half!)

You can see the page in question here: http://www.jadeboylan.com/game/post.php

The code here: http://pastebin.com/gUMSqJYy

Any help would be greatly appreciated!

try this

<?php
 
        $funds       =    $_POST['prcbox'];
        $ageval       =   $_POST['age'];
 
        echo "You have $funds to spend!";
 
?>
 
<input type="hidden" id="age" name="age" value="$ageval">

fgetcsv_PHP();
 
function fgetcsv_PHP()
{
    /*
     * See if we can open a file named fgetcsv.csv in
     * read mode, if we can then assign pointer to this
     * file to a variable named $handle
     * 'r' - Open for reading only; place the file
     *  pointer at the beginning of the file.

         * it to 0 in PHP 5.0.4 and later) the maximum line length is not
         * limited, which is slightly slower.
         *

         *       comprising a single null field, and will not be treated
         *       as an error.
         *
         * Note: If PHP is not properly recognizing the line endings when
         *       reading files either on or created by a Macintosh computer,
         *       enabling the auto_detect_line_endings run-time configuration
         *       option may help resolve the problem.
         *
         * fgetcsv() returns NULL if an invalid handle is supplied or FALSE
         * on other errors, and when the end of file has been reached.
