Hide Dashboard Login Errors In WordPress

In this tutorial, I'm going to show how you can easily hide login errors in WordPress. It's a great way to protect from WordPress from hackers. Whenever you login with the correct username but with the wrong password, a message appears saying "Error: Incorrect Password." WordPress has now given a clue to hacker that the username entered is in the system, and that they simply need to crack its password.

Similarly, an "Error: Invalid username" also appears when you enter an unavailable username. It's better for you to prevent hacking by hiding this error message. In order to keep this from happening, you need to add this code to your functions.php file:

add_filter('login_errors', create_function('$a', "return null;"));

This filter code will remove error message from the login page. The error box will still appear, but without any text.

How To Automatically Empty Trash In WordPress

The Trash feature was introduced in WordPress 2.7, and since then, if you click "Trash" for any item, it will be sent to the trash. It works similar to the Recycling Bin feature on Windows. By default, the content you trash remains there for 30 days before being permanently deleted. However, you can also delete items from the Trash at any time.

You can also modify the 30 day period with some simple codes. Just add this line to wp-config.php and you’re done:

define('EMPTY_TRASH_DAYS', 5 ); // Empty trash every 5 days

How To Create A Custom Dashboard Widgets In WordPress

Earlier this hour I was surfing thru WordPress' official codex website and I found something very interesting to write about. Okay! I know you guys are so exited about this great trick.

The Dashboard Widgets API (added in WP 2.7) makes it very simple to add new widgets to the administration dashboard. It only takes a few minutes to create a simple dashboard widget for your blogger. It can be a great way to make your plugin and themes even more useful.

How To Create A Custom Dashboard Widgets:

 This code would go in one of your plugin's files, or in your theme's functions.php:

/**
 * Add a widget to the dashboard.
 *
 * This function is hooked into the 'wp_dashboard_setup' action below.
 */
function example_add_dashboard_widgets() {

    wp_add_dashboard_widget(
                 'example_dashboard_widget',         // Widget slug.
                 'Name of your widget',          // Title.
                 'example_dashboard_widget_function' // Display function.
        );   
}
add_action( 'wp_dashboard_setup', 'example_add_dashboard_widgets' );

/**
 * Create the function to output the contents of our Dashboard Widget.
 */
function example_dashboard_widget_function() {

    // Display whatever it is you want to show.
    echo "<p>Welcome to BWidgets! Need help? Contact the developer <a href="mailto:yourusername@gmail.com">here</a>.</p>";
} 

That's it! Red part in the above code is the title and content area of our widget. Don't forget to leave a comment if you need any help with this tutorial.

How To Add Extra Fields To WordPress User Profile Page

Yesterday I post an article about removing some extra fields (AIM, Yahoo IM, and Jabber) from WordPress' user profile page area. It's time to dig even more deeper into this trick. It's time for us to learn about adding some extra fields to user profile page.

The code below will show you how to add additional Twitter and Facebook fields, but you can use it to add any other field that you like. Add following php code to your theme's functions.php file (from theme editor):

function my_new_contactmethods( $contactmethods ) {
// Add Twitter
$contactmethods['twitter'] = 'Twitter username (withour @';
//add Facebook
$contactmethods['facebook'] = 'Facebook';
return $contactmethods;
}
add_filter('user_contactmethods','my_new_contactmethods',10,1);

That's it.

How To Stop Users With AdBlock In Blogger/WordPress

Don't you hate it when a crappy extension is blocking you from getting the payoff of your hard work that you put on your blog? Not sure about you, but I really really hate that. More than AJ Styles-Dixie Carter's TNA Promo that I'm watching right now, it's good. Okay, it was a creative way to end the show.

Back to topic. Antiblock.org found a great script to stop users with AdBlock from viewing your website. Don't forget to check and support their awesome project. There is no bad in stopping users with AdBlock from viewing your site because we blogger needs to earn as much as we can for our hard work. It's not easy to run and manage a full time blog without revenues from ads. Here is how to do it:

Stop Users With AdBlock In Blogger/WordPress/HTML:

First of all, you can also use this script on any other blogging/site platform. It works everywhere, even on a HTML page.

For Blogger:

• Visit Blogger > Template > Edit HTML.

• Press Ctrl + F and search for ]]></b:skin> and paste below code above it:

#g207{position:fixed!important;position:absolute;top:0;top:expression((t=document.documentElement.scrollTop?document.documentElement.scrollTop:document.body.scrollTop)+"px");left:0;width:100%;height:100%;background-color:#fff;opacity:0.9;filter:alpha(opacity=90);display:block}#g207 p{opacity:1;filter:none;font:bold 16px Verdana,Arial,sans-serif;text-align:center;margin:20% 0}#g207 p a,#g207 p i{font-size:12px}#g207 ~ *{display:none}

• Now press Save Template.

• Now navigate to Blogger > Layout > Add Gadget, Click on HTML/JavaScript Gadget.

• Paste the below code into it and press Save.

<script>(function(w,u){var d=w.document,z=typeof u;function g207(){function c(c,i){var e=d.createElement('i'),b=d.body,s=b.style,l=b.childNodes.length;if(typeof i!=z){e.setAttribute('id',i);s.margin=s.padding=0;s.height='100%';l=Math.floor(Math.random()*l)+1}e.innerHTML=c;b.insertBefore(e,b.childNodes[l-1])}function g(i,t){return !t?d.getElementById(i):d.getElementsByTagName(t)};function f(v){if(!g('g207')){c('<p>Please disable your ad blocker!<br/>This site is supported by the advertisement <br/> Please disable your ad blocker to support us!!! </p>','g207')}};(function(){var a=['Adrectangle','PageLeaderAd','ad-column','advertising2','divAdBox','mochila-column-right-ad-300x250-1','searchAdSenseBox','ad','ads','adsense'],l=a.length,i,s='',e;for(i=0;i<l;i++){if(!g(a[i])){s+='<a id="'+a[i]+'"></a>'}}c(s);l=a.length;for(i=0;i<l;i++){e=g(a[i]);if(e.offsetParent==null||(w.getComputedStyle?d.defaultView.getComputedStyle(e,null).getPropertyValue('display'):e.currentStyle.display)=='none'){return f('#'+a[i])}}}());(function(){var t=g(0,'img'),a=['/adaffiliate_','/adops/ad','/adsales/ad','/adsby.','/adtest.','/ajax/ads/ad','/controller/ads/ad','/pageads/ad','/weather/ads/ad','-728x90-'],i;if(typeof t[0]!=z&&typeof t[0].src!=z){i=new Image();i.onload=function(){this.onload=z;this.onerror=function(){f(this.src)};this.src=t[0].src+'#'+a.join('')};i.src=t[0].src}}());(function(){var o={'http://pagead2.googlesyndication.com/pagead/show_ads.js':'google_ad_client','http://js.adscale.de/getads.js':'adscale_slot_id','http://get.mirando.de/mirando.js':'adPlaceId'},S=g(0,'script'),l=S.length-1,n,r,i,v,s;d.write=null;for(i=l;i>=0;--i){s=S[i];if(typeof o[s.src]!=z){n=d.createElement('script');n.type='text/javascript';n.src=s.src;v=o[s.src];w[v]=u;r=S[0];n.onload=n.onreadystatechange=function(){if(typeof w[v]==z&&(!this.readyState||this.readyState==="loaded"||this.readyState==="complete")){n.onload=n.onreadystatechange=null;r.parentNode.removeChild(n);w[v]=null}};r.parentNode.insertBefore(n,r);setTimeout(function(){if(w[v]!==null){f(n.src)}},2000);break}}}())}if(d.addEventListener){w.addEventListener('load',g207,false)}else{w.attachEvent('onload',g207)}})(window);</script>

That's it!

For WordPress:

It's all same for WordPress. Just add following CSS & JavaScript code to your WordPress template:

CSS:

#g207{position:fixed!important;position:absolute;top:0;top:expression((t=document.documentElement.scrollTop?document.documentElement.scrollTop:document.body.scrollTop)+"px");left:0;width:100%;height:100%;background-color:#fff;opacity:0.9;filter:alpha(opacity=90);display:block}#g207 p{opacity:1;filter:none;font:bold 16px Verdana,Arial,sans-serif;text-align:center;margin:20% 0}#g207 p a,#g207 p i{font-size:12px}#g207 ~ *{display:none}

JavaScript:

<script>(function(w,u){var d=w.document,z=typeof u;function g207(){function c(c,i){var e=d.createElement('i'),b=d.body,s=b.style,l=b.childNodes.length;if(typeof i!=z){e.setAttribute('id',i);s.margin=s.padding=0;s.height='100%';l=Math.floor(Math.random()*l)+1}e.innerHTML=c;b.insertBefore(e,b.childNodes[l-1])}function g(i,t){return !t?d.getElementById(i):d.getElementsByTagName(t)};function f(v){if(!g('g207')){c('<p>Please disable your ad blocker!<br/>This site is supported by the advertisement <br/> Please disable your ad blocker to support us!!! </p>','g207')}};(function(){var a=['Adrectangle','PageLeaderAd','ad-column','advertising2','divAdBox','mochila-column-right-ad-300x250-1','searchAdSenseBox','ad','ads','adsense'],l=a.length,i,s='',e;for(i=0;i<l;i++){if(!g(a[i])){s+='<a id="'+a[i]+'"></a>'}}c(s);l=a.length;for(i=0;i<l;i++){e=g(a[i]);if(e.offsetParent==null||(w.getComputedStyle?d.defaultView.getComputedStyle(e,null).getPropertyValue('display'):e.currentStyle.display)=='none'){return f('#'+a[i])}}}());(function(){var t=g(0,'img'),a=['/adaffiliate_','/adops/ad','/adsales/ad','/adsby.','/adtest.','/ajax/ads/ad','/controller/ads/ad','/pageads/ad','/weather/ads/ad','-728x90-'],i;if(typeof t[0]!=z&&typeof t[0].src!=z){i=new Image();i.onload=function(){this.onload=z;this.onerror=function(){f(this.src)};this.src=t[0].src+'#'+a.join('')};i.src=t[0].src}}());(function(){var o={'http://pagead2.googlesyndication.com/pagead/show_ads.js':'google_ad_client','http://js.adscale.de/getads.js':'adscale_slot_id','http://get.mirando.de/mirando.js':'adPlaceId'},S=g(0,'script'),l=S.length-1,n,r,i,v,s;d.write=null;for(i=l;i>=0;--i){s=S[i];if(typeof o[s.src]!=z){n=d.createElement('script');n.type='text/javascript';n.src=s.src;v=o[s.src];w[v]=u;r=S[0];n.onload=n.onreadystatechange=function(){if(typeof w[v]==z&&(!this.readyState||this.readyState==="loaded"||this.readyState==="complete")){n.onload=n.onreadystatechange=null;r.parentNode.removeChild(n);w[v]=null}};r.parentNode.insertBefore(n,r);setTimeout(function(){if(w[v]!==null){f(n.src)}},2000);break}}}())}if(d.addEventListener){w.addEventListener('load',g207,false)}else{w.attachEvent('onload',g207)}})(window);</script>

That's it. You can also use this plugin to stop users with AdBlock with some extra options.

How To Remove User Contact Info From WordPress Profile Page

After writing bunch of articles about WordPress' wp-config.php file, it's time for me to write some articles about the powerful functions.php file. And I'll start from the start. In this post, I'm sharing a very simple and useful trick for WordPressers (WordPressers :p).

Most of us never ever used three fields on the WordPress profile page and so we want to remove those fields. They are the fields for AIM, Yahoo IM, and Jabber. It's time to get rid of these fields:

Add following php code to your theme's functions.php file (from theme editor):

add_filter('user_contactmethods','hide_profile_fields',10,1);
function hide_profile_fields( $contactmethods ) {
unset($contactmethods['aim']);
unset($contactmethods['jabber']);
unset($contactmethods['yim']);
return $contactmethods;
}

That's it..!!

How To Change The Default WordPress Media Uploads Folder

I'm really loving all the wp-config.php tricks. We can do so much amazing stuff with just some little codes.

Before WordPress 3.5 you used to be able to change the upload directory path from the Settings menu in the dashboard. However, now you can't do anything like that from the settings option, but it’s still possible.

How to Change The Default WordPress Media Uploads Folder:

Open wp-config.php (located in root of WordPress installation) and add following code before the line that says require_once(ABSPATH.’wp-settings.php’);.

define( 'UPLOADS', 'wp-content/custom-path' );

Change wp-content/custom-path with your custom upload path. For example, you can can change it to wp-content/files. Don't forget to add the code before require_once(ABSPATH.’wp-settings.php’);.

3 Ways To Disable WordPress AutoSave

This is my second post of the day here on BWidgets, and it's also about Daniel Bryan wp-config.php file and WordPress AutoPost. This time I'll show you one three ways to disable WordPress AutoSave feature.

When editing a post, the changes you make are automatically saved every 2 minutes. You can also use our last trick to Modify AutoSave Interval.

By Editing wp-config.php File:

This is the easiest way to disable WordPress AutoSave feature. To modify autosave interval simply open wp-config.php (located in root of WordPress installation) and add following code to the end of file:

define('AUTOSAVE_INTERVAL', 86400);

We've set WordPress AutoSave interval to 86400 seconds which is an entire day. So this effectively disables the autosave functionality. Thanks to Jacob Nicholson for the idea.

By Editing post.php File:

This is the smartest way to disable AutoSave feature without any heavy codes. Thanks to Shane G. for sharing this trick on a WordPress forum.

• Open your wp-admin/post.php file and wp-admin/post-new.php files.

• You will find this line of code there:

wp_enqueue_script('autosave');

• Add // to the beginning of this code. It'll look something like this:

// wp_enqueue_script('autosave');

The AutoSave option will be disabled for your existing and new posts.

By Editing functions.php File:

Last but not the least. This is the most preferred way to disable this feature, as we don't have to re-edit our post.php and post-new.php file after every WordPress update, nor we have to adjust AutoSave interval. This trick will simple disable AutoSave feature. Thanks to Egill R. Erlendsson for sharing this trick on a WordPress forum.

Simple throw this in your functions.php file:

add_action( 'admin_init', 'disable_autosave' );
function disable_autosave() {
        wp_deregister_script( 'autosave' );
}

That's it folks. Thanks for all amazing guys that I mentioned on the article for sharing these amazing tricks around the internet. Don't forget to give us a backlink if you're sharing this article on your blog.

Modify WordPress AutoSave Interval

Here we're again! Another post about my favorite Pokemon WordPress core file. YES! YES! YES, this post is also about Daniel Bryan wp-config.php file.

When editing a post, the changes you make are automatically saved every 2 minutes. It seems bit weird, but you can actually change the setting for longer delays in between auto-saves, or decrease the setting to make sure you never lose changes.

And we don't need a crappy plugin for this simple hack. Technically, it's not even a hack, but a simple option described in original WordPress codex.

Modify WordPress AutoSave Interval:

To modify autosave interval simply open wp-config.php (located in root of WordPress installation) and add following code to the end of file:

define('AUTOSAVE_INTERVAL', 160 );  // seconds

Replace 160 with your custom autosave interval (in seconds).

Save your config.php file & that's it!

How To Disable Or Limit WordPress Post Revisions

Post Revisions are a feature introduced in WordPress 2.6. A revision is automatically stored in your database, whenever you save or draft a post or a page. Earlier this year, I posted an article about Deleting Old WordPress Post Revisions at this link.

Today we're going to learn a very simple tweak to disable or limit WordPress post revisions without installing any crappy plugin, which saves a lot of space. We just have to add a little snippet to your our config.php file.

Limit WordPress Post Revisions:

To limit Post revisions simply open wp-config.php (located in root of WordPress installation) and add following code to the end of file:

define('WP_POST_REVISIONS', 3);

Replace 3 with maximum number of Post revisions per post/page.

Disable WordPress Post Revisions:

To disable Post revisions simply open wp-config.php (located in root of WordPress installation) and add following code to the end of file:

define('WP_POST_REVISIONS', false );

 Save your config.php file & that's it!
