The maximum length that you can store in a column of each data type is given below.

      Type | Maximum length
  TINYTEXT |           255 (2 8−1) bytes
      TEXT |        65,535 (216−1) bytes = 64 KiB
MEDIUMTEXT |    16,777,215 (224−1) bytes = 16 MiB

Refresh (or) Reload Web Page using Meta Tag

You can refresh (or) reload HTML web page using meta tag without script tag as given below.

<meta http-equiv="refresh" content="5">

The above code will reload the same page in 5 seconds.

To reload the page immediately you should set content="0".

Redirect to Specific URL

To redirect the page to different URL you should follow the code as given below.

<meta http-equiv="refresh" content="5;url=">


  • Meta tag is always placed inside the <head> tag.
  • Meta tag provides information about contents in the html page.

Should I put input elements inside a label element?

The label itself may be positioned before, after or around the associated control.

Example 1:

<label for="lastname">Last Name</label>
<input type="text" id="lastname" />

Example 2:

<input type="text" id="lastname" />
<label for="lastname">Last Name</label>

Example 3:

    <input type="text" name="lastname" />
    Last Name

Note: the third technique cannot be used when a table is being used for layout, with the label in one cell and its associated form field in another cell.

Either one is valid. I like to use either the first or second example, as it gives you more style control.

How to use .htaccess file on an Apache Localhost Server

.htaccess is a configuration file that should be stored where your page is.

In short, it should be in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\ (or) custom folder --> D:\dev\www\.

Don't forget to turn on mod_rewrite by deleting a hash from the line where it resides LoadModule rewrite_module modules/ and enable .htaccess by changing AllowOverride None to AllowOverride All

This was clearly explained as follows:

  1. Find your apache directly which uses the php installation
  2. Open your httpd.conf with notepad, Which is located in the path \apache\conf directory
  3. Find the code like below
#LoadModule rewrite_module modules/
  1. Remove # from above code
  2. Make sure the line is AllowOverride None as shown below.
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
AllowOverride All <--- change this line to AllowOverride None
  1. Save httpd.conf file
  2. Restart your apache server

What is the best way to reload (or) refresh an iframe using JavaScript?

Solution 1:


be careful, in Firefox, window.frames[] cannot be indexed by id, but by name or index.

Solution 2:

document.getElementById('iframeid').src = document.getElementById('iframeid').src;

It will reload the iframe, even across domains! Tested with IE7/8, Firefox and Chrome.

Solution 3:

If using jQuery, this seems to work:

$('#iframeid').attr('src', $('#iframeid').attr('src'));

There are 2 methods to send HTML form data from 1 Page to another or HTML page to server side in PHP.


It is a method in which data gets sent using packet which is not visible to any user on web-browser. it is secured compared to GET method.


It is a method in which data gets sent with URL which is visible to user in address-bar of any web-browser. So, it’s not secure as POST method.

Now, There are total three methods to catch this data in PHP.

  • POST: It can catch the data which is sent using POST method.
  • GET: It can catch the data which is sent using GET method.
  • REQUEST: It can catch the data which is sent using both POST & GET methods.

Archaeological Importance of Tirukoilur

It has a number of temples both Vaishnava and Saiva sects, was once a capital of an important chieftain Malayaman of Sangam age datable to 3rd century BCE to 3rd century CE. To corroborate this, a Tamil Brahmi inscription at Jambai (near Tirukkovilur ) mentions about the king AthiyamanNedumanAnchi as SathiyaPutoAtiyanNedumanAnjihiIttaPali. MalaiyamanTirumudikkari was the illustrious ruler of this dynasty. The Sangam works speak of the invasion of Tirukkoilur and defeat of MalayamanTirumudikkari by NedumanAnji, king of Takadur (modern Dharmapuri) who is said to have offered Avvaiyar, the celebrated poetess (of that period), a myrobalan (gooseberry) fruit to increase her longevity.

Tirukkoilur seems to have been as important a religious center as Kanchipuram in Tondaimandalam. There is ample evidence to prove that Vaishnavism, Saivism and Jainism had flourished at this center. It is said the MudalAlvars, the first three Alvars, (Poigai, Butham and Pei) were made to meet by the grace of Almighty in one place at Tirukkoilur and in ecstasy they sang poems on Ulagalandaperumal; these songs were known as Divyaprabhandam. The presiding deity of the temple TiruvikramaPerumal is still a wooden image and this retains its ancient character.

Tirukkoilur, which is also famous for Saivism, was sung by the Saiva saints as one of the Ashtavirattanams.

Kabilar rock stands in south pennarriver.It was named after Kabilar, a sanga poet who is friend and guide of parivallal.

Arakandanallur/ Aramkandanallur (Aram + Kanda + Nalla + oor) is a small village located near Tirukoilur. It has a Shiva temple (Athulyanatheswarar) built on a rock, very close to the banks of the river. This temple has archaeological importance. It has cave rooms carved out of the rock and it also has a sub-way inside of another adjacent rock leading to veemankundru. Local people believe that PanchaPandavas lived here during their time of Vanavasa. It is believed that Ramana Maharishi visited this temple.

How to change your default Index page in htaccess

Paste the following code at the top of the .htaccess file to configure your desired index page.

In the example below, we decided to make the index page of our folders named first.html.

#Alternate default index page
DirectoryIndex first.html

You can also list more than one file in the configuration.

The file will be read left to right and check for them in that order.

In this example, we add index.htm, index.html, and index.php to the list.

#Alternate default index pages
DirectoryIndex first.html index.htm index.html index.php

First the server will check for first.html, if it does not find a file with that name, it continues to index.htm and so on.

Formatting date to human readable in PHP

Lets say in mysql database have a timestamp 2013-09-30 01:16:06 and lets say this variable is $ts.
To show more like September 30th, 2013 follow the examples.

Example 1

$timestamp = "2013-09-30 01:16:06";
echo date("F jS, Y", strtotime($timestamp));

Note the use of S to get the english ordinal suffix for the day.
Since you're already using strtotime if you need a human readable data for the current time you can just use the keyword "now" as in strtotime("now").

Example 2

Use strtotime() to convert that string into a Unix Timestamp, then use the date() function to display it like you want

echo date("F j, Y, g:i a",strtotime($timestamp));
echo date("F d Y",strtotime("2013-09-30 01:16:06"));

Example 3

I do not think that php is even needed there. Check MySQL DATE_FORMAT() function.

SELECT DATE_FORMAT('2013-09-30 01:16:06', '%M %D, %Y %H:%i:%s') as `readable`;

Result: September 30th, 2013 01:16:06

For real usage:

SELECT DATE_FORMAT(`date_column`, '%M %D, %Y %H:%i:%s') as `readable`
FROM `your_table`;

How to increase array size limit in PHP?

You could be running out of memory, as your array size is (in theory) only limited by the amount of memory allocated to the script.

Put ini_set('memory_limit', '1024M'); in the beginning of your script to set the memory limit to 1GB.

You may need to increase this even higher for best results.

Sri Raghottama Theertha chose Tirukoilur as his headquarters to spread the Dwaita Siddhanta in the country while Gnanananda Giri Swamiji established 'Tapovanam', to encourage the study of Vedanta. Also a Gnanasiddha, he cured diseases through his Siddha medicines. Jeeyar Madom was founded here by Sree Emperumanaar to spread Vaishnavism during the 16th Century.

The poet who wrote Tirukoilur Sathakam (a collection of 100 poems) Kavimamani Uthiyan (38) is incidentally, the present president of the Tirukoilur Tamil Sangam. He has authored seven novels, 400 dramas and around 2000 poems. He is the Indian representative to the "World Tamil Poets Organisation" headquartered in Malaysia.

Unique are the temples here, so too the idols. The ten feet tall idol of Varadaraja Perumal in Manampoondi, built in stone during the Pallava period is in meditating sitting posture. The p73 Sreedevi and Bhoodevi idols are six feet tall; the Sthalapuranam reveals that both goddesses had meditated here. The Vamana idol in the Ulagalanda Perumal temple is one of the three such rare idols in the country. The second is in Srirangam, the third in Rishikesh. The Vishnu's idol in the Ulagalanda Perumal temple is 16 feet tall. The Ten feet tall Sivalingam of the Pallava period carved in stone, in the Vellai Ganapathy temple is yet another attraction. The Rajagopuram of the Trivikrama Temple is the fourth largest height wise in Tamil Nadu. The 1300 year old Siva temple stands as a memorial to the killing of Andhakaasura by Lord Siva. The marriage hall just outside the temple was constructed during the Vijayanagara period, in the 14th Century. Ganesha, seated south west of this temple has been worshipped by poetess Avvayar (7th Century) "Seetha kamala poomporpada kamalam".

History reveals that one among the eight Veerateshwara (Siva) temples, in the country, is in Tirukoilur, also worshipped by Appar and Tirugnanasambandar and saints such as Arunagirinathar and Ramana Maharshi.

The Aathulyannatha temple (Siva) with Goddess Arul Nayaki built in the 7th Century during the Pallava period is situated on the northern bank of the River South Pennar on a flattened rock. The Rajagopuram faces south while the main temple faces west. Five caves beneath and a temple tank are other features of this temple.

Srivilliputhur Alwar, lived here during the 14th Century. Swami Shanathananda Saraswathi had his schooling in Tirukoilur, before becoming the disciple of Swami Gnanananda Giri, who directed him to take sannyas from the Himalayan sage Swami Sivananda.

Sanskrit scholar Krishna Premi predicts that Varadaraja Perumal at Manampoondi will have a great temple in the days to come. The idol is at present under a temporary shelter. The temple built in the 8th Century is believed to have been destroyed in the 12th Century by floods. Nowadays, poojas are offered on a daily basis.

The Tirukoilur Cultural Society has been conducting "KapilarVizha", an annual affair (May 1 to 4) with unabated regularity for the last 19 years.

"KapilaVaanar" title is also presented by the society to up and coming poets, annually. "With better roads, more informative literature in English, the Tourism Department can attract more tourists to Tirukoilur".

Is it still valid to use IE=edge,chrome=1?

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> serves two purposes.

  1. IE=edge specifies that IE should run in the highest mode available to that version of IE as opposed to a compatability mode; IE8 can support up to IE8 modes, IE9 can support up to IE9 modes, and so on.
  2. chrome=1 specifies that Google Chrome frame should start if the user has it installed

The IE=edge flag is still relevant for IE versions 10 and below. IE11 sets this mode as the default.

As for the chrome flag, you can leave it if your users still use Chrome Frame. Despite support and updates for Chrome Frame ending, one can still install and use the final release. If you remove the flag, Chrome Frame will not be activated when installed. For other users, chrome=1 will do nothing more than consume a few bytes of bandwidth.

I recommend you analyze your audience and see if their browsers prohibit any needed features and then decide. Perhaps it might be better to encourage them to use a more modern, evergreen browser.

Note, the W3C validator will flag chrome=1 as an error: A meta element with an http-equiv attribute whose value is X-UA-Compatible must have a content attribute with the value IE=edge.

த்ரிவிக்ரம அவதாரம் - திருக்கோவிலூர்

முன்னொரு காலத்தில் 'மஹாபலி' என்று புகழ் பெற்ற அஸுரன் ஒருவன் இருந்தான். அவன் தான, தர்மங்களில் மிகவும் சிறந்தவனாக இருந்த போதிலும் தேவர்களை மிகவும் கஷ்டப்படுத்திக் கொண்டிருந்தான். அவனது கொடுமையைத் தாங்காது தேவர்கள், ஸித்தர்கள், முனிவர்கள் யாவரும் திருப்பாற்கடலையடைந்து பகவானை சரணடைந்தனர். அப்பொழுது ஸ்ரீமந் நாராயணன் அவர்களுக்குப் ப்ரத்யக்ஷமாகி மஹாபலியை அடக்குவதாக வாக்களித்து அபயங் கொடுத்து மறைந்து விட்டார். அந்த ஸமயத்தில் கச்யபர் தனது பார்யையான (மனைவி) அதிதியுடன் புத்ரன் வேண்டுமென்று புத்ரகாமேஷ்டி செய்தார். அப்பொழுது யக்ஞ புருஷனான நாராயணன் வாமன மூர்த்தியாக அவதரித்தான். வாமன பகவான் ப்ரம்மசர்ய ஆச்ரமம் பெற்றதும் பலிச் சக்ரவர்த்தியிடம் பூதானம் வேண்டி வந்து சேர்ந்தான். இவ்வுலகை படைத்த ஸர்வேஸ்வரனே வாமன ரூபியாக வந்திருக்கிறான் என்று அறியாத பலிச்சக்ரவர்த்தி அவருக்கு விசேஷமாக பூஜை செய்து எது வேண்டுமானலும் தானம் செய்வதாக வாக்களித்தான். அது கேட்டு உள்ள முகந்த எம்பெருமான், "அப்படியாகில் என் திருவடிகளால் மூன்றடி மண் கொடு" என்று கேட்டான்.

வாமன மூர்த்தியான ஹரியின் கபடத்தைக் கண்ட சுக்ராச்சாரியார் தனது சிஷ்யனான மஹாபலியிடமுள்ள பரிவினால் வந்திருப்பது ப்ராமணன்ல்ல மாயா ப்ரம்ம சாரியான விஷ்ணு வேதான் என்று சொல்லிக் காட்டிக் கொடுத்து விட்டார். ஆனால் தைர்யசாலியான பலியோ ஸாக்ஷாத் திருமகள் கேள்வனான நாராயணனே என்னிடம் கை நீட்டி தானம் வாங்குவது எனக்குப் பெருமையே, என்னிடம் தானமும்பெற்றுக் கொண்டு என்னை நிக்ரஹம் செய்தாலும் அல்லது அனுக்ரஹம் செய்தாலும் சொன்ன சொல் மீற மாட்டேன் என்று சொல்லி குருவை மீறி பகவானுக்கு மூன்றடி மண் தானம் செய்து விட்டான்.

அப்பொழுது பகவான் உடனே வாமன ரூபத்தை விட்டு விராட் புருஷ ரூபத்தை எடுத்துக் கொண்டு ஒரு திருவடியால் பூமியையும், மற்றொரு திருவடியால் விண்ணுலகையும் அளந்தான். அப்பொழுது த்ரிவிக்ரம ரூபத்தைக் கண்ட தேவர்கள், முனிவர்கள், ஸித்தர்கள், கின்னரர்கள் யாவரும் பலவாறு துதித்துக் கொண்டாடினார்கள். ப்ரம்ம தேவனும் உயரத்தூக்கப்பட்ட திருவடியில் தனது கமண்டலுவிலுள்ள தீர்த்தத்தினால் பாத்யம் கொடுத்து பூஜித்தார். அந்த பாத்ய தீர்த்தமே கங்கையென்னும் பெயருடன் உலகில் பெருகி ஓடுகிறது.

மூன்று அடி தருவதாகச் சொன்ன மஹாபலியின் சொல்படி பூலோகத்தையும் ஸ்வர்க்கத்தையும் இரண்டு அடிகளாக அளந்து விட்டபடியால் மூன்றாவது அடி எங்கே என்று கேட்டு பகவான் மஹாபலியை அதட்டினான். பகவான் பெருமையை அறிந்த மஹாபலி, "நாராயணா" எனது ஸத்யத்தைக் காப்பாற்ற வேண்டியது உமது கடமை. உமது திருவடியால் அடியேனது தலையை அளந்து கொண்டு என் உடைமை யாவையும் உமதாக ஏற்றுக் கொண்டது போல் அடியேனையும் ஏற்றுக்கொள்ள வேண்டும் என்று வேண்டினான். உடனே பகவானும் மஹாபலியின் தலை மேல் தனது திருவடியை வைத்து அனுக்ரஹித்து இரண்டு லோகமும் எனக்கு தானம் கொடுத்து விட்டபடியானதினால் இனி இங்கு இருக்ககூடாது. பாதாளத்திற்க்குப் போ வென்று சொல்லி அனுப்பினான். அவனிடம் கருணையுடன் பகவானும் அவன் பாதாளத்தில் இருக்குமிடத்தில் தானே வாசற்காப்பாளனாக இருந்து அவனுக்குக் காக்ஷியளிக்கிறான்.

தேவர்கள், முனிவர்கள் யாவரும் தங்கள் காரியம் பலித்துவிட்ட படியால் பகவானைத் துதித்தனர். இந்திரனிடம் மூவுலக ராஜ்யத்தையும் கொடுத்து விட்டு சங்க, சக்ர தாரியான பகவான் யாவரும் பார்த்துக் கொண்டிருக்கும் போதே மறைந்து விட்டார்.

How To Change WordPress Attachment Page Image Size?

Medium size is the default value of attachment page image size in WordPress. Medium size images perfectly matched for some themes only. Most of the themes need full size or large size images in attachment page because these values only fixed for the themes width. Let checkout how to the WordPress attachment page image size.

For change the image size you don’t need to edit the theme files. You need to edit a "post-template.php" file from "wp-includes" directory. Never forget this file will be rewritten after updating the WordPress sometimes. So you need edit this file again if the attachment page image size changed to default value after the WordPress update.


  1. Edit "post-template.php" file from "wp-includes" folder
  2. Find this code wp_get_attachment_link(0, 'medium'
  3. Change the default value medium to full or large
  4. Click save or update to save this changes. Attachment page image size will be changed immediately once you have done this update.

Post thumbnails from external URLs don’t appear in Blogger. How to resolve?

You can solve this issue by using <data:post.firstImageUrl/> tag instead of <data:post.thumbnailUrl/> in the blogger code (or) template.


<b:if cond='data:post.firstImageUrl'>
    <a class='wdxthumb' expr:href='data:post.url' expr:title='data:post.title'>
        <img class='post-thumbnail' expr:alt='data:post.title' expr:src='data:post.firstImageUrl'/>
    <a class='wdxthumb' expr:href='data:post.url' expr:title='data:post.title'>
        <img alt='no image' class='post-thumbnail' src=''/>

Note: <data:post.firstImageUrl/> tag will return both Picasa hosted images as well as external images.

For the related post widget, you will have to make changes to the code to parse out the Image URL from the HTML response in case the image is not uploaded to Picasa storage.

What is the difference between "ng-bootstrap" and "ngx-bootstrap"?

ng-bootstrap and ngx-bootstrap are two different projects by two different project teams that are trying to accomplish more or less the same thing - allowing you to use Bootstrap in Angular (2+) without the use of jQuery.

They are both rebuilding the Bootstrap components using only Angular (no jQuery).

The main differences are around which version of Bootstrap they support.

  • ngx-bootstrap supports Bootstrap 3 and 4.
  • ng-bootstrap supports Bootstrap 4 and requires Angular 5+.

This means that if you need to use Bootstrap version 3, then ngx-bootstrap is your only real option of the two. If you can use Bootstrap 4, then you can pick between the two projects.

The other (potentially significant) difference is the teams behind the projects.

The key point to note in this regard is that the team behind ng-bootstrap was also responsible for angular-ui-bootstrap - the AngularJS (i.e. 1.x) version of the Bootstrap library.

Motorola Razr hands on: The revived RAZR is a Fashion-Forward Foldable

Motorola has resurrected its beloved Razr phone, a staple of mid-2000s cool, as a foldable device. The new Razr distinguishes itself from the Galaxy fold and Huawei's Mate X by folding vertically instead of horizontally. Unfolded, it looks like a regular smartphone, albeit one with a chunky "chin", but folded in half it's practically pint-sized, with a small front display to see your notifications, control media, or take a selfie. There's still a lot of questions when it comes to durability and foldables, but the new Razr feels extremely well constructed, and folds in half with no visible gap. It does have a few downsides, including a mid-range processor, single camera, and questionable battery capacity, but this is the first foldable we could see ourselves using as a daily device.
