Laravel 4.x setting in production and development

Surely, in production use you don’t want to show any error to the user. In simple way, you can set debug to false:
/app/config/app.php

return array (

'debug' => false,

[...]

)

For complete setting for development and production, you can try;
/app/bootstrap/start.php

$env = $app->detectEnvironment(array(
	'local' => array('localURL.com'),
	'production' => array('productionURL.com')
));

Define your file/folder configuration for every situation (development/production):

app
app/config
app/config/local
app/config/local/app.php
app/config/local/database.php
app/config/production
app/config/production/app.php
app/config/production/database.php

Easiest way to write library in Laravel

Sometimes you have change a lot in your Laravel configuration and folder. This will avoiding running composer again.

First, just open your /app/start/global.php. Add a folder libraries (whatever you want):

app_path().'/commands',
app_path().'/controllers',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/libraries',

And now you can add any file in your libraries folder.

Example:

<?php

/* File: Bantu.php */

class Bantu {

    public static function write( $message ) {

        echo $message;

    }

}

Non Alpha Numeric Regex with Javascript

Using javascript regular expressions to stop users from entering non-aphanumeric characters or white spaces

Say you want to stop users from entering non-aphanumeric characters or white spaces.

Using regular expressions would be the easiest method:

Here is my javascript code:

<script language="Javascript">
function alphaNumericCheck(){
    var regex=/^[0-9A-Za-z]+$/; //^[a-zA-z]+$/
    if(regex.test(document.add_data.password.value)){
        alert("Good")
        return true;
    } 
    else {
        alert("Please fix: password")
        return false;
    }
}
</script>

For numbers only use /^[0-9]+$/

For mixed text and numbers, with spaces /^[0-9a-zA-Zs]+$/

Here are more useful regular expressions:

[a-zA-Z] any letter
d any number; same as [0-9]
D any NOT number; same as [^0-9]
w any alphanumeric character; same as [a-zA-Z-0-9_]
W any NON-alphanumeric character; same as [^a-zA-Z0-9_]
s any whitespace (tab, space, newline, etc...)
S any NON-whitespace
n newline
t tab
