Thread: Security Image Array Contains 0 and o

The security image array should not contain 0 (zero) or the letter O or o as this confuses people and causes failure of the security image.

This is an easy fix.

Edit /simg/simg.php and remove the letter o from the

Code:

$chars = array

You may also want to consider using only numbers 2 through 9, and no letters by editing

Code:

$chars = array

And reducing the number of characters shown to 4, be editing

Code:

for ($i = 0, $length = 6; $i < $length; $i++) {

to

Code:

for ($i = 0, $length = 4; $i < $length; $i++) {

none of these fixes worked for me

Not work

Smoge please upload your simg.php to the forum...

I can't even produce a security image. All is has is a black background with 'Error Producing Security Image'.

Me too :S :S :S:S:S:S:S

Two things going on in this thread:

The original topic which was - shorten and change to only numbers - this does work - here is a snippet of a portion of the original simg.php

Code:

ob_start();
session_start();
$chars = array("a","b","c","d","e","f","h","i","k","m","n","o","r","s","t","u","v","w","x","z","2","3","4","5","6","7","8","9");
/*
$chars = array("a","A","b","B","c","C","d","D","e","E","f","F","g","G","h","H","i","I","j","J",
			   "k","K","L","m","M","n","N","o","p","P","q","Q","r","R","s","S","t","T",
			   "u","U","v","V","w","W","x","X","y","Y","z","Z","2","3","4","5","6","7","8","9");
*/
$textstr = '';
for ($i = 0, $length = 6; $i < $length; $i++) {
   $textstr .= $chars[rand(0, count($chars) - 1)];
}
$hashtext = md5($textstr);
$_SESSION['strSec'] = $hashtext;

and this section, modified to show only 4, of only numbers.

Code:

ob_start();
session_start();
$chars = array("2","3","4","5","6","7","8","9");
$textstr = '';
for ($i = 0, $length = 4; $i < $length; $i++) {
   $textstr .= $chars[rand(0, count($chars) - 1)];
}
$hashtext = md5($textstr);
$_SESSION['strSec'] = $hashtext;

As for "I can't even produce a security image. All is has is a black background with 'Error Producing Security Image'." - this is a seperate issue from this thread. Many reasons for this - please do some searching on ModMySite "security image" for help - or start a new thread about this.
