 Posted: Sat Jul 24, 2004 9:58 pm Post subject: Error 404 when using PHP_SELF |
 |
|
I am trying out a test script:
| Code: |
<html>
<head>
<title>Learning PHP</title>
</head>
<body>
<?php
if($submit){
// Process Form
$db = mysql_connect("127.0.0.1", "root", "pcegib");
mysql_select_db("mydb", $db);
$sql = "INSERT INTO employees(first,last,address,position) VALUES ('$first','$last','$address','$position')";
$result = mysql_query($sql);
echo "Thank you! Information entered.\n";
} else {
// Display Form
?>
<form method="post" action="<?php echo $PHP_SELF ?>">
First Name: <input type="text" name="first"><br>
Last Name: <input type="text" name="last"><br>
Address: <input type="text" name="address"><br>
Position: <input type="text" name="address"><br>
<input type="submit" name="submit" value="Enter Information">
</form>
<?php
} // end if
?>
</body>
</html>
|
The problem is, when I run the page the first time around, I get this above the form:
Notice: Undefined variable: submit in d:\html\cgi-bin\test\RES\add_entry.php on line 9
And if I fill in the form and submit it, I get an Error 404 (not found) and the URL in the address bar is this:
http://127.0.0.1/cgi-bin/test/RES/%3Cbr%20/%3E%3Cb%3ENotice%3C/b%
3E:%20%20Undefined%20variable:%20%20PHP_SELF%20in%20%3Cb%3Ed:
%5Chtml%5Ccgi-bin%5Ctest%5CRES%5Cadd_entry.php%3C/b%3E%20on%2
0line%20%3Cb%3E20%3C/b%3E%3Cbr%20/%3E
I have the REDIRECT_STATUS set at 200. I had to set it like that or any images shown in a php file (like phpMyAdmin) would automatically launch my Paint Shop Pro program to display each image.
How do I get the above code/form to work? I just upgraded recently to Abyss Web Server X1 (v 1.2.2.2) and this didn't use to be a problem in earlier versions. Earlier versions ran the above script fine, and I had back then set the REDIRECT_STATUS to CGI. Now it has to be set at 200 and my forms don't work. :(
Anyone know of a fix? |

Correct me if I'm wrong, but I believe you're using the old variable naming convention. Instead of using $submit, use $_POST['submit'], or change "register_globals" in the php.ini file to "on."

MetroSpectre,
Your code is using the old PHP variable names convention.
* Solution 1: If you don't want to change your code, open php.ini and set register_globals to on
* Solution 2: change $PHP_SELF with $_SERVER['PHP_SELF'] and $submit with $_POST['SUBMIT'].
More information is available by searching this forum for 'undefined variable' or in http://www.php.net/reserved.variables .

Thanks folks, that worked. :)
I also tried doing this, just for the heck of it (instead of $_SERVER['PHP_SELF']):
$PHP_SELF=$HTTP_SERVER_VARS['PHP_SELF'];
Which works in this:
<form method="post" action="<?php echo $PHP_SELF ?>">
Is that ok? What is the difference between $_SERVER and $HTTP_SERVER_VARS?
(note that I just edited this post because I found that it does work both ways - I just didn't catch all the PHP_SELF's while trying this in code :) ) |

MetroSpectre,
$_SERVER is the new way of calling $HTTP_SERVER_VARS since PHP 4.1.0. $HTTP_SERVER_VARS is still available for backward compatibily, but it is preferred to use $_SERVER instead for any new code you write.

| Thank you. :) I think that I'll do things that way then in the future. |
