Differences between character counting in PHP and Javascript

I’ve recently codded my own validation rules for forms. I’m checking length of a string on a client side and also on a server side (obviously it’s a good practice). After my script went on a production, users started to complain about validation errors (even if data in a form was passed proper). This is really strange but…

How to add Bower component when it’s not in the repository?

Sometimes component that you want to use in your project isn’t available in Bower repo. There is a way to install it, even in very specified version. Go to project’s Github, in my case it’s here. Copy URL from the browser, and paste it somewhere. Now go to relases and click commit id that you’re interested in (this random blue colored string):

After that you’ll see full commit id, in this case it’s fef978b279c546923ad4f4118acea4d503e7596c. Paste that to the end of repository URL you’ve copied earlier. Remember to prefix it with # char and add .git to the URL:

https://github.com/bfintal/Counter-Up.git#fef978b279c546923ad4f4118acea4d503e7596c

Finally mix it with your bower.json file. Here’s full example:

{
	"name": "Realhero report",
	"description": "Report template based on New Age",
	"main": "index.js",
	"authors": ["Konrad Fedorczyk"],
	"license": "ISC",
	"homepage": "http://realhe.ro",
	"private": true,
	"ignore": ["**/.*", "node_modules", "bower_components", "test", "tests"],
	"dependencies": {
	    "bootstrap": "^3.3.7",
	    "font-awesome": "^4.6.3",
   	 	"jquery": "^1.11.3",
   	 	"simple-line-icons": "^2.3.2",
   	 	"morris.js": "^0.5.1",
   	 	"jqvmap-fedek6": "https://github.com/fedek6/jqvmap.git#774c12a57916ab82e17406203bb41522dfe0e38b",
   	 	"Counter-Up": "https://github.com/bfintal/Counter-Up.git#fef978b279c546923ad4f4118acea4d503e7596c"
	}
}

Look at the last line of dependencies part, here’s component that I’ve added.

How to change mass edit limit in Vtiger 6.5

Sometimes you need to make mass operation on houndreds of records in Vtiger. Well in this case it’s 500 ones maximum… Well this is kinda stupid because it can surely handle up to thousands. How do I know? I’ve hacked the code and successfully converted 2000 leads 🙂 Well it takes some time but it definitely works!

Let us return to the merits. You need to edit a file from root folder of your Vtiger 6.5 CRM, placed here /layouts/vlayout/modules/Vtiger/resources/List.js. Simply find the code below and edit number according to your needs:



File: List.js
-------------

		var selectedCount = this.getSelectedRecordCount();
		if(selectedCount > 2000) {
		    var params = {
			    title : app.vtranslate('JS_MESSAGE'),
			    text: app.vtranslate('JS_MASS_EDIT_LIMIT'),
			    animation: 'show',
			    type: 'error'
		    };
		    Vtiger_Helper_Js.showPnotify(params);
		    return;
		}

Simpliest way to obfuscate e-mail address using jQuery

Here is a simpliest jQuery code to protect e-mail addresses on your website from spam bots. Just put this in a script tag into the head section:

$(window).load(function() {			
	// anti spam
	var r='random-string';
 
	$('.'+r).each(function() {
	var $this = $(this),
		value = new String($this.text());
 
		value = value.replace('['+r+']', '@');
 
		$this.replaceWith($('<a></a>').text(value).attr('href', 'mailto:'+value));
	});
});

Now replace random-string with any really aleatory set of characters eg. dhhIDu338

And here is the HTML part. Publish every e-mail address on your page using this code:

Contact: <span class="random-string">johndoe[random-string]mail.com</span>
