PLEASE HELP!! Can't get ID from URL...whats the problem???

Bl4ckMaj1k · March 22, 2011

Good evening my PHP experts!!!

OK so heres the problem...I have been at this for about 2 DAYS now and for the life of me I just don't understand what I could possibly be doing wrong.

I have 3 of 4 variables outputting correctly but without my id being pulled from the URL NOTHING will get written to my database. I have ran some tests and I came to learn that my $_POST['id']; function is not working properly for some strange reason. As always, any help would be greatly appreciated. Please see below PHP code. I also have posted the HTML code for your reference purposes...thanks in advance. Please helpppp!!!!

<?php

session_start();

$id = '';

if (isset($_POST['password'])) {

include_once "scripts/connect_to_mysql.php";

$id = $_POST['id'];
$id  = mysql_real_escape_string($id );
$id = eregi_replace("`", "", $id);


    $cust_password = $_POST['password'];
    $hashedPass = md5($cust_password); 

$sql = mysql_query("UPDATE customers SET password='$hashedPass' WHERE id='$id'");

$update_success = 'You have successfully updated your Password. Please click <a href="customer_login.php">HERE</a> to log into your account.';

//Output to test whether or not my variables have anything in them.
//$update_success, $hashedPass, $cust_password all Output just fine. $id displays nothing at all.	
echo $update_success;
echo $hashedPass;
echo $cust_password;
echo $id;

exit();

}

?>

If id is appended to the URL string, it will be in the $_GET array, not the $_POST array . . .

Bl4ckMaj1k · March 22, 2011

I have tried $_GET, $_POST, and $_REQUEST....still nothing. My $id variable will not echo anything neither will any data get written to the table.

P.S. if I am using method="POST"; in my HTML form, will PHP still allow me to gather data using $_GET? Someone told me yesterday that its not possible.

P.S.S. I am literally smiling ear to ear seeing the speedy reply.....WOW!!! YAY!!! :-)

Yeah, even if the form method is post, you can still send a 4_GET var by tacking it onto the form's action= attribute. To see what you're actually getting, put this at the top of the script and look at its output after the form has been submitted.

echo '$_POST array:<pre>';
print_r($_POST);
echo '</pre>$_GET array:<pre>';
print_r($_GET);
echo '</pre>';

Edit: fixed bbcode tags.

Interesting. Here is the PHP with the function you advised I add to top of code:

<?php

session_start();

echo '$_POST array:<pre>';
print_r($_POST);
echo '</pre>$_GET array:<pre>';
print_r($_GET);
echo '</pre>';

$id = '';

if (isset($_POST['password'])) {

include_once "scripts/connect_to_mysql.php";

$id = $_GET['id'];
    $id  = mysql_real_escape_string($id );
    $id = eregi_replace("`", "", $id);

$cust_password = $_POST['password'];
    $hashedPass = md5($cust_password); 

//$sql = mysql_query("UPDATE customers SET password='$hashedPass' WHERE id='$id'");

$update_success = 'You have successfully updated your Password. Please click <a href="customer_login.php">HERE</a> to log into your account.';
echo $update_success;
echo $hashedPass;
echo $cust_password;
echo $id;

exit();

}

?>

And here is what was output to page:

$_POST array:

Array

(

[password] => christopher

[submit_password] => Submit Password

)

$_GET array:

Array

(

)

You have successfully updated your Password. Please click HERE to log into your account.0a909ffe7be1ffe2ec130aa243a64c26christopher

And at that point, is there still a key=value pair appended to the URL string in the address bar of your browser?

Please post your form.

EDIT

I DID IT!!!!!! I FIXED IT!!!!! Finally WOWWWW!!! I am SOOOOO proud of me right now!!

Here is what I did.

First, I changed the following:

if (isset($_POST['password'])) {

include_once "scripts/connect_to_mysql.php";

$id = $_GET['id'];
    $id  = mysql_real_escape_string($id );
    $id = eregi_replace("`", "", $id);

to:

include_once "scripts/connect_to_mysql.php";

$id = $_GET['id'];
    $id  = mysql_real_escape_string($id );
    $id = eregi_replace("`", "", $id);
    if (isset($_POST['password'])) {

Then I went into the HTML of the code and changed the following:

<form action="cust_acc_conf.php" method="post" id="form" name="form" enctype="multipart/form-data" onsubmit="return validate_form ( );">
<div id="login_header">

to:

<form action="cust_acc_conf.php?id=<?php echo $id ?>" method="post" id="form" name="form" enctype="multipart/form-data" onsubmit="return validate_form ( );">

This wouldn't work for me before because the $id variable wasn't being returned UNLESS I hit the submit button. Now that its outside of the if condition, it stores it in the $id variable without any necessary action required. This makes it accessible whenever I need it, not just when a button is pressed. Wow sometimes all you need is a push in the right direction. Thank youuuuuuuuuu!!!!!!!

And at that point, is there still a key=value pair appended to the URL string in the address bar of your browser?

P.S. The answer to this was NOOOO!!!! And I totally get it!! My form wasn't returning the variable to the URL.....so how would it POSSIBLY have anything to capture....wow PHP makes SOOOO much sense!!!! :-)

I <3 this place already!!!!!!
