UPgrade to php 5.5 causes null values to be passed from value= clause

@rfintzOct 05.2015

My web hosting site has been upgrading us from php 5.2 to php 5.5 or 5.6. Over the weekend after being upgraded to 5.5 I noticed most of my php programs had failed to process due to the fact that the “value=” clause of the <input tag was passing nulls instead of the specified values. I have a ticket open with the hosting site but I was wondering if anyone encountered this type of issue. Below is a sample of the html I’m using followed by some php code. THanks in advance for any help.

HTML:

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd“>
<html xmlns=”http://www.w3.org/1999/xhtml“>

<input type=”radio” value=”status.php” id=”sub1″ name=”sub” checked=”checked” /><label
for=”sub1″> Display Current Weekly Pool Standings</label>
<input type=”hidden” name=”week” length=2 maxlength=2 value=’04’ readonly

PHP:

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd“>
<html xmlns=”http://www.w3.org/1999/xhtml“>

@ $db = mysql_connect(‘weknowth.ipowermysql.com’,’xxxxx’,’yyyyyy’);

$query=”SELECT coverteam1,coverteam2
from game where week='”.$week.”‘”;

The value of week should have been passed as ’04’ instead it was a null value.

If you are depending on PHP to automatically create and populate the $week variable, then you are depending on the register_globals feature/option, which has been deprecated for many years as a security risk, and finally completely removed as of PHP 5.4.8.

@rfintzauthorOct 06.2015 — #The issue re-occurred last night, however this time it was on the older php release (5.2). I spoke with someone at my web hosting site who felt it was a problem with the php.ini parameter session.save_path not being set correctly. He fixed that and upgraded me to 5.3. Let's see how it goes. Below is the form tag I'm using.

function submitTheForm(oFrm){

for(var i = 0;i < oFrm.sub.length;i++){

if(oFrm.sub[i].checked) {

oFrm.action = oFrm.sub[i].value;

return true

<form action="" method="post" onsubmit="return submitTheForm(this)">

<fieldset>

<input type="submit" value="Submit" />
</fieldset>

@ginerjmOct 06.2015 — #Why do you insist on posting incomplete and confusing pieces of code? First it was two input elements but no form. Now it's a JS function with no end and poor logic. And you give us a START of a form but no input elements and no END of the form.

Is this truly how you code or just a test to see if forum readers are that gullible?

If you want help you must post what you are working with so that we can see what is in front of you. NOT your whole script but at the least the parts that are part of your dilemma.

@rfintzauthorOct 06.2015 — #I apologize, I'm an amateur at this and had help developing it. It's definitely not a test for gullibility, just ignorance on my part.

I'm posting a majority of the html I'm using:

@ginerjmOct 06.2015 — #What a piece of work!! Whoever helped you with this is quite behind the times.

You are using some very complex stuff to do what is essentially a simple thing.

1 - problem. You can't "check" all 3 radio buttons. That's the whole concept behind radio buttons - you can only select ONE! If you want to select multiple things you use a - check box!

2 - Stop repeating the css stuff in each element. You use a css block in your html code to do that for you.

3 - Stop using the font tag as a stand-alone tag. Besides - you only have an 'end' font tag and no beginning one, so you're half right.

Here's how I would tackle this:

[code=php]
 <?php
 session_start();
 // ALWAYS TURN ON ERROR CHECKING DURING DEVELOPMENT!!!
 error_reporting(E_ALL | E_NOTICE);
 ini_set('display_errors', '1');
 //*****************************
 //   if no submitted 'btn' tag, just display the selection menu
 if (!isset($_POST['btn']))
 {
 DisplayPage();
 exit();
 }
 //   got a submitted btn - grab it and analyze it.
 $btn = $_POST['btn'];
 //*****************************
 if ($btn == "Display this week's Player's Picks")
 {
 //   jump to display.php
 header("Location: display.php");
 exit();
 }
 //*****************************
 if ($btn == 'Display Current Weekly Pool Standings')
 {
 //   jump to status.php
 header("Location: status.php");
 exit();
 }
 //*****************************
 if ($btn == 'Head to the football forum')
 {
 //   jump to build_forum.php
 header("Location: build_forum.php");
 exit();
 }
 //*****************************
 //  handle an undefined button
 echo "Unhandled button name - $btn";
 exit();
 //*****************************
 function DisplayPage()
 {
 $code=<<<heredocs
