Absolutely Position Element Within a Table Cell

-
Image
Absolutely Position Element Within a Table Cell   Have you ever wanted to absolutely or relatively position a table cell? Well, I can't help you there. Table cell elements just won't take those position values. And thus, you also can't absolutely position elements within the context of those elements either. I can help you out with that issue. The answer is just to make a generic wrapper element inside the table cells (the exact same size of the table cell) and use that as the relative positioning context. Non-semantic? Yep, but we'll chuck that markup in with JavaScript so it's not a big deal. Kludgy fix? You know it. Does it work? Sure does. # Before < table > < tr > < td > < img src = " yay.jpg " alt = " " > </ td > </ tr > </ table > # After < table > < tr > < td > < div class = " innerWrapper " > <!-- appen...

A beginner’s guide to writing title tags and meta descriptions that get clicks

-
Image
A beginner’s guide to writing title tags and meta descriptions that get clicks It’s true: title tags and meta descriptions won’t help your website magically rise to the top of the search engine results. Google confirmed it back in 2007 so let’s kill that myth right at the outset. However, these two elements can improve click through rates and entice people to click on your link rather than the link of one of your competitors. So why do site owners neglect title tags and meta descriptions, pushing them to the back burner? Title tags and descriptions tell search engines and users what your site is about. They describe the content on each page of your website and explain how it relates to a user’s search query. And, when used properly, they can act as a “hook” of your advertising in the search engine results. If you don’t know what title tags and meta descriptions are, why they’re important and how to write them to get more prospects to click on your links in search engine results, we’ll...

How To Use HTML Meta Tags

-
Image
Want top search engine rankings? Just add meta tags and your website will magically rise to the top, right? Wrong. Meta tags are one piece in a large algorithmic puzzle that major search engines look at when deciding which results are relevant to show users who have typed in a search query. While there is still some debate about which meta tags remain useful and important to search engines, meta tags definitely aren’t a magic solution to gaining rankings in Google, Bing, Yahoo, or elsewhere – so let’s kill that myth right at the outset. However, meta tags help tell search engines and users what your site is about, and when meta tags are implemented incorrectly, the negative impact can be substantial and heartbreaking. Let’s look at what meta tags are, what meta tags matter, and how to avoid mistakes when implementing meta tags on your website. What Are Meta Tags? HTML meta tags are officially page data tags that lie between the open and closing head tags in the HTML code of a document....

Meta tags that Google understands

-
Meta tags that Google understands Meta tags are a great way for webmasters to provide search engines with information about their sites. Meta tags can be used to provide information to all sorts of clients, and each system processes only the meta tags they understand and ignores the rest. Meta tags are added to the <head> section of your HTML page and generally look like this: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="Description" CONTENT="Author: A.N. Author, Illustrator: P. Picture, Category: Books, Price: £9.24, Length: 784 pages"> <meta name="google-site-verification" content="+nxGUDJ4QpAZ5l9Bsjdi102tLVC21AIh5d1Nl23908vVuFHs34="/> <title>Example Books - high-quality used books for children</title> <meta name="robots" content="noindex,nofollow"> Google understands the following meta tags (and related items): ...

  The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets. Initializing the Class Like most other classes in CodeIgniter, the Table class is initialized in your controller using the $this->load->library function: $this->load->library('table'); Once loaded, the Table library object will be available using: $this->table Examples Here is an example showing how you can create a table from a multi-dimensional array. Note that the first array index will become the table heading (or you can set your own headings using the set_heading() function described in the function reference below). $this->load->library('table'); $data = array( array('Name', 'Color', 'Size'), array('Fred', 'Blue', 'Small'), array('Mary', 'Red', 'Large'), array('John', 'Green', 'Medium') ); echo $this->table->generate($data)...

PHP Tutorial - PHP Constants

-
Image
Constants are used to make sure a value does not change throughout the running of the script. Syntax To define a constant, use the define() function, and include name of the constant, followed by the value for the constant, as shown here: define( "MY_CONSTANT", "1" ); // MY_CONSTANT always has the string value "1" Note Constants may only contain scalar values such as Boolean, integer, float, and string (not values such as arrays and objects). Constants can be used from anywhere in your PHP program without regard to variable scope. Constants are case-sensitive. Example 1 <?PHP define( "aValue" , 8); print aValue; ?> The code above generates the following result. Example 2 Pass in true as a third parameter to define() makes the constant case-insensitive: <?PHP/* w ww .ja va2s . co m*/ define( "SecondsPerDay" , 86400, true); print SecondsPerDay; print SECONDSperDAY; ?> The code above generates the following resul...

PHP Tutorial - PHP Integer

Integers hold whole numbers, either positive or negative, such as 1, -20, 12345,etc. The limit of integer is between -2147483647 and 2147483647. The integer numbers outside the range are automatically converted to floats. The following code adds two integer values together in PHP. <?php /* w w w. j a v a 2 s.com*/ $var1 = 5; $var2 = 2; $answer = $var1 + $var2; print "$var1 plus $var2 equals $answer." ; ?> The code above generates the following result. PHP integer Literal We may specify integers in hexadecimal (base 16) or octal (base 8). The octal number system only uses the digits 0 to 7. hexadecimal uses 0 to 9, then A, B, C, D, E, and F. To specify number in octal, we must precede it with a 0 (zero). <?PHP $octalnum = 06331; print $octalnum; ?> The code above generates the following result. Hexadecimal To specify a number in hexadecimal, precede it with 0x . <?PHP $hexnum = 0x44; print $hexnum; ?> The code above generates the following result. Examp...

Booleans hold either true or false. Behind the scenes, booleans are integers. false value In addition, PHP considers the following values to be false : The literal value false The integer zero (0) The float zero ( 0.0 ) An empty string ( " " ) The string zero ( "0" ) An array with zero elements The special type null (including any unset variables) A SimpleXML object that is created from an empty XML tag All other values are considered true in a Boolean context. We can assign true or false value to a boolean type variable. <?PHP/* w w w . j av a2 s . c o m*/ $bool = true; print "Bool is set to $booln" ; $bool = false; print "Bool is set to $booln" ; ?> The code above generates the following result. Example 2 In the second if statement we compare the integer value to a boolean value. <?PHP/* w w w .j a va 2 s . c o m*/ $a=100; if ($a==100) { echo "the variable equals 1!n" ; } if ($a=...

Tutorial - PHP Data Types

-
Image
PHP has seven data types. The seven types are: string, integer, float, boolean, array, object, and resource. String Strings hold characters such as "a," "abc," "www.java2s.com," etc. PHP strings are case-sensitive. Object Objects are complex variables that have multiple values, and they can have their own functions. Resource Resources might be picture data, or the result of an SQL query. We should free up resources after using them. PHP References Reference type variables are actually pointer to the real data. Once two variables are pointing to the same data, you can change either variable and the other one will also update. When you use the = (assignment) operator, PHP takes the value from operand two and copies it into operand one. Syntax To assign by reference, you need to use the reference operator ( & ) after the equals operator (=), giving =& . Example <?PHP/*from w w w . j av a2 s . com*/ $a = 10; $b =& $a; ...
