Stuck in wordpress Maintenance Mode?

Are you Stuck in wordpress Maintenance Mode?  I was in that situation and thought to write about my pain and findings so that it may be help to reduce pain in the ass when u are crazy to do some upgrade for plugins and themes and you are stuck  in maintenance mode for “something wrong” in upgrade/upadte process .

This tip is for wordpress3.0+, don’t  know what to do for lower version.  The thing is when wordpress takes the site maintenace mode it creates a file in the site root dir named .maintenance  and when done remove that… 🙂

So, now you know what to do if u are stuck in maintenance mode. I wish I am going to sleep well tonight.

note: check the dicussion in wordpress forum about this issue.

btw, let me show you a sample screenshot about how the error msg look for upgrade failure

Adding joomla native dropdown menu in frontend

joomla native drop down menu


I think it’s my 4th post about using joomla native resources like tab slider, tooltip, modal/popup window and I am very happy that I just tried to used the joomla admin top menu … the top to bottom drop down menu in front end and it’s working fine. I just used the joomla native resources and changed one line of code in mod_mainmenu module. I think for doing something test or creative things sometimes we can try to change core code little… just keep in mind where u are changing and change again while u upgrade again in future.

Ok then let’s move for how we can use the main menu module as ‘top to bottom‘ drop down menu like the joomla admin panel top menu. we will work on default template of joomla1.5 Continue reading →

Fix wp plugin “Post and Page Excerpt Widgets” not to break conditional tag

Post and Page Excerpt Widgets is a nice plugin to show post/page excerpt as as widget in sidebar position. You can download it from wp code from here. One I thing I noticed about this plugin is it has a common bug that I faced many times while using query_posts. When I use this query_posts it’s break some conditional loop like is_home(), is_category() etc but there is another function get_posts in wordpress that does the same thing but don’t have similar problem. Once I discussed about this problem in one of my old posts. Please check that posts for better sense from here is_home-is_single-is_category-is-not-working-in-wp!.

Let me focus to this writing again 😀
As Post and Page Excerpt Widgets is using the query_posts function for custom query it make’s problem for conditional tags. Let me show u solution and it’s like my that posts.

Send ajax request in wordpress using wpnonce

wpsecuritythumblet’s send ajax request in wordpress using wpnonce

Hei, I am not going to discuss what is wpnonce and why you should use this in your plugin or how important to use this to secure your plugin 😛
But here I am going to discuss how you can use wpnonce in ajax request, I mean if your plugin handles ajax request.
Steps that we need to follow are:

One: Create wpnonce value.
Two: Send wpnonce value as an extra parameter with ajax requestion
Three: Check ajax referrer with the wpnonce value that was created in step one and sent in step two.

Ok, how to create a wpnonce value ?
we need to use wordpress function wp_create_nonce() . See wordpress codex here.
< ?php $my_wpnonce= wp_create_nonce (‘you-look-nice’); ?> // “you-look-nice” is just a string, u can use whatever u want. here $my_wpnonce will get a hash from wp_create_nonce. Oh that is not direct hash of “you-look-nice” but based on user id, time and that string. To know more about this function please check pluggable.php in wp-includes folder

Now send wpnonce value $my_wpnonce as an extra parameter while seding ajax req. Continue reading →
