Need help with this script

$Three3 · December 9, 2009

Hi, I have been stuck on this for a while now. I am really new to PHP and I cannot get the script below to display the html form. I have tried practically everything but it is just not working for me. It just displays a blank page. Any help is greatly appreciated. Also, ever since I have switched over to a new server, I have not been able to get any errors to display while testing my scripts. How can I go about getting the errors turned back on? Thanks

to turn on errors, add these lines to the top of you PHP scripts, immediately following the <?php:

<?php
ini_set ('display_errors', 1);
error_reporting (E_ALL);

see what errors come up and post them here.

Okay I just added that to the top but it still gives me a blank page. I even tried it on the little script below but it still does not display any errors.

<?php

ini_set ('display_errors', 1);
error_reporting (E_ALL);

for ($i = 1 ; $i <= 10 ; $i++) {
echo $i 

?>

<?php
//Try to open the file to write to
   
   if ($fp = fopen('../userinfo/userinfo.txt' , 'ab')) {
      //this line gives a parse error because you have incorrectly concatenated "<br />" to $_POST['password1'] .. you're missing a .
      $data = $_POST['username'] . "<br />" . $_POST['email'] . "<br />" $_POST['password1'] . "\n" ;

change that to:

<?php
//Try to open the file to write to
   
   if ($fp = fopen('../userinfo/userinfo.txt' , 'ab')) {
      $data = $_POST['username'] . "<br />" . $_POST['email'] . "<br />" . $_POST['password1'] . "\n" ;

remove the opening <?php of course. but that will work now.

Lol wow. A couple of days for a missing period. Thanks a lot man! Lol. If you do not mind also, is there anyway to get an error on something like this?

LAST EDIT: if my memory serves me correct, i don't believe enabling error_reporting at runtime will display parse errors since the server parses the file before it executes any code, and ini_set() & error_reporting() being code, will not be parsed, therefore, reporting will not be set.

if you have access to your php.ini file, you will have to set the appropriate values in there.

-----

check to make sure that your web server has "write" permissions to it's default logging directory (or the logging directory specified in your php.ini file)

EDIT: will be this line in php.ini file:

error_log = c:/path/to/php_error.log

make sure that the directory (and file itself) have write permissions.

NOTE: each log file is also assigned an allotted size as well, meaning that it can fill up, and if full will not be writable anymore, also causing errors not to show. just something in case anybody was wondering.

hope this helps since knowing what errors are occurring is a HUGE help/time(sanity)-saver in development.
