Why hook_form not working

Why hook_form not working

Hi Googler,

i was working on drupal and come to know this problem, 

I have a module which I have defined a hook_form hook,
but it was not working, after some investigation I have found that hook_form is only called when a node type is defined by a module.
so, what is mean by “a node type defined by a module”?
In drupal , we can define a module type in 2 place, one is in module’s installation file.
for example:




$test_type = array(
    ‘type’ => ‘test’,
    ‘name’ => st(‘Test’),
    ‘module’ => ‘node’,
    ‘custom’ => TRUE,
    ‘modified’ => TRUE,
    ‘locked’ => FALSE,
  );
  $test_type = (object) _node_type_set_defaults($test_type);
  node_type_save($test_type);




above code, create a node type through “node_type_save” , function.
the other place is use hook_node_info function in a module file.
for example:


function test_node_info() {
  return array(
    ‘teiqcase’ => array(
      ‘name’ => t(‘test’),
      ‘module’ => ‘test’,
      ‘description’ => t(“Test”),
      ‘has_title’ => TRUE,
      ‘title_label’ => t(‘Test’),
      ‘has_body’ => FALSE,
      ‘body_label’ => t(‘Body’),
    ),
  );
}




above also create a node type ‘test’ , but this one did not use ‘node_type_save’ function, hence, it called “a node type defined by a module”.
so to make a node type work with “hook_form”, we should not use ‘node_type_save’ to define a node type, but use “hook_node_info” to define a node type
above only works for Drupal 6, drupal 7′s hook_form is totally different.

Using regular expressions to extract content - php extract texts from html content

Hello PHP Googler,

PHP provides a number of really neat regular expression functions. You can find the list of the regex function at the PHP site.

But the one that I’ve had most fun with is the preg_match_all() function which I’ve been using to do content extraction from an HTML page.

I’m not going to explain what Regular Expression (regex) is in this post. There are whole books on just this one topic along; I would be crazy to think I can explain it all in just a few paragraphs. But in order for you to understand how to use the regex functions you need to have a basic understanding of regular expressions.

If you think back to your childhood days, you would remember a toy that you can match holes with shapes with the corresponding blocks – like the picture here. Well, regular expressions is very much like that toy, but instead you have define your own ’shape’ (or pattern as it’s known) and apply your content to it. Any text that matches the pattern will ‘fall’ through it.

Let’s say you have a block of text like below and you want to extract out the all links from, you can use preg_match_all to do just that.

 
$content = "He's goin' everywhere, <a href=\"http://www.bjmckay.com\">B.J. McKay</a> and his best friend Bear. Rollin' down to <a href=\"http://www.dallas.net\">Dallas</a>, who's providin' my palace, off to New Orleans or who knows where." 
The pattern you want to look for would be the link anchor pattern, like <a href=”(something)”>(something)</a>. 
The actual regular expression might look something like Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this
$regex_pattern = "/<a href=\"(.*)\">(.*)<\/a>/";

Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this
preg_match_all($regex_pattern,$content,$matches); print_r($matches);
preg_match_all will store all the matches into the array $matches, so if you output the array,
you’ll see something like this.

Array ( [0] => Array ( [0] => <a href="http://www.bjmckay.com">B.J. McKay</a> [1] => <a href="http://www.dallas.net">Dallas</a> ) [1] => Array ( [0] => http://www.bjmckay.com [1] => http://www.dallas.net ) [2] => Array ( [0] => B.J. McKay [1] => Dallas ) )



From this array, $matches, you should be able to loop through and get the information you need.

I hope this has been useful to you. I know it doesn’t cover all the things this function can do, but for first-timers, it should be a simple look at a very powerful PHP function.

Incidently, PHP also provides the function preg_match(). The difference is preg_match() only matches a single instance of the pattern, whereas preg_match_all() tries to find all matching instances within the content.

Hardening Your Web Application Against SQL Injections

Hi All,


Before digging what actually SQL Injection is, let me explain you what is SQL it self.
What is SQL?


Structured Query Language (SQL) is a specialized programming language for sending queries to databases. Most small and industrial- strength database applications can be accessed using SQL statements. SQL is both an ANSI and an ISO standard. However, many database products supporting SQL do so with proprietary extensions to the standard language. Web applications may use user-supplied input to create custom SQL statements for dynamic web page requests.


What is SQL Injection?


SQL injection is a technique that exploits a security vulnerability occurring in the database layer of a web application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed. It is in fact an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another.
“SQL Injection” is subset of the unverified/unsanitized user input vulnerability (“buffer overflows” are a different subset), and the idea is to convince the application to run SQL code that was not intended. If the application is creating SQL strings naively on the fly and then running them, it’s straightforward to create some real surprises.


Many organization’s web servers has been compromised just because of SQL Injections, including big names which I would not like to mention here, you can search it easily on Internet.


What is Blind SQL Injection?
This particular type of attack is called a blind SQL injection attack, because the attacker cannot take advantage of detailed error messages from the server or other sources of information about the application. Getting the SQL syntax right is usually the trickiest part of the blind SQL injection process and may require a lot of trial and error. But, by adding more conditions to the SQL statement and evaluating the Web application’s output, an attacker will eventually determine whether the application is vulnerable to SQL injection.


Blind SQL injection a special case that plays on the web developers or website owners sense of security. While they may think that everything on the server is tightly guarded a Blind SQL injection attack will silently be playing truth or consequences with the web server. This type of attack though very time consuming is one that provides the most potentially damaging security hole. This is because an attacker gets not only access but is provided with an enormous amount of knowledge about the database and can potentially gain access to a servers file system. This type of attack is one that is automated and requires good amount of setup to succeed. But once it is done it does not require a great deal of effort to repeat.
What is Error message SQL Injection?


Web applications commonly use SQL queries with client-supplied input in the WHERE clause to retrieve data from a database. When a Web application executes such queries without validating or scanning the user-supplied data to ensure it’s not harmful, a SQL injection attack can occur. By sending unexpected data, an attacker can generate and submit SQL queries to a web applications database. A test for SQL injection vulnerabilities takes place by sending the application data that generates an invalid SQL query. If the server returns an error message, that information can be used to try to gain uncontrolled access to the database. This is the basis of one of the most popular SQL injection attacks.
Hiding error messages does not stop the SQL injection attack. What typically happens is the attacker will use the knowledge gained from the failure of this attack to change tactics. What they turn to is blind SQL injection.


What is SQL Injection?

When a web application fails to properly sanitize user-supplied input, it is possible for an attacker to alter the construction of backend SQL statements. When an attacker is able to modify a SQL statement, the process will run with the same permissions as the component that executed the command. (E.g. Database server, Web application server, Web server, etc.). The impact of this attack can allow attackers to gain total control of the database or even execute commands on the system.

PHP Development India – Best Language for Web Development

In today’s advanced technological world, the popularity of the internet has been increasing and we see millions of websites running on the internet to fulfill the requirement of user and the figure keeps increasing each day. Therefore, the merchants are getting cut-throat competition on the internet. Strong representation of a website is thus necessary for its online success. Hence, merchants have been diverted to web development industry to build the strong online presence.

There are many options available for web development like php, asp.net, java, wordpress, etc., from them php becomes a first choice for company websites. Because PHP is an open source server side scripting language, which allows effective web development at affordable rates. PHP support multiple platforms and databases such as Linux kernel, MS Windows, MySQL, MS Access, SQL server & Oracle. It also offers an array of other features which can be used to make a website flexible and user-friendly.

Benefits of PHP Development:

• Create a dynamic website that has a professional look
• Its support various OS (operating system) like Windows, Linux and Unix
• The coding is easily understandable
• Web development at very affordable rates
• Increase your ROI (Return of Investment)

Many countries provide php development services, from them India has taken first place in this field because Indian php developers offer excellent designing and development services and take new challenges with open arms and most important thing, you get your application at one-quarter of cost at your current rate.

Timezones in MySQL and PHP

Hay Googler,


Timezones in web applications are often dealt with the same way as character sets. Either incorrectly or ignored. The case of unicode is improving slowly as developers discover the need for international language support.


The problem with not handling timezones correctly is not apparent in the usual case of the webserver and the database server being in the same timezone. A lot of PHP code passes the task of timestamps on to MySQL, e.g. by calling NOW() on inserting or updating records. It is nessesary to know in what timezone the timestamps are stored to process them correctly.
Often a specific timezone is assumed for displaying date and time. This could very well be incorrect for a large number of visitors. If the database server is in yet another timezone, things begin to get out of sync.
MySQL's handling of timezones is - obviously - separate from that of PHP. Along with the fact that the MySQL timezone can only be changed by users with SUPER privileges, this means that MySQL cannot be relied on for creation of timestamps in correct timezone. In other words, the usual call toNOW() is not an option.
PHP 5.1 introduced the date_default_timezone_set() method for setting the timezone PHP will use for functions like date() (or alternatively the date.timezone php.ini directive). This allows for a flexible and consistent way of creating timestamps in the correct timezone form within PHP. One user in London might start a thread while a response comes from New York. To handle this consistently and make sure both users see local time and the correct timespan between the posts, use date_default_timezone_set() to create the timestamps from PHP in a fixed timezone like GMT.
Time for an example to illustrate the practical use of this. I created a simple class Timer for dealing with these operations. The methods will be called statically as there is no need to instantiate the class.


---------------------------------------------------------------------------------------

class Timer 
{   
    static function DatetimeInGMT() {
        return date("Y-m-d H:i:s", time()-date("Z",time()));
    }

    static function GMTDatetimeToLocal($datetime) {
        $time = strtotime($datetime);
        return date("Y-m-d H:i:s", $time+date("Z",$time));
    }
}
--------------------------------------------------------------------------------------------------------------------------------

Timer::DatetimeInGMT() produces a timestamp in GMT. I use it instead of MySQL's NOW()because it calculates the time relative to the timezone set in PHP rather than that of MySQL.



When reading the timestamp back in to PHP, another function call is needed to convert it back to whatever timezone PHP is in at that time (it might be a different user viewing with another timezone setting). That's the job of Timer::GMTDatetimeToLocal($datetime).
These two very simple functions and a correct setting of PHP's timezone will ensure that dates are stored in a consistent way and displayed correctly.

Importance of PHP Development for Web development

One of the biggest examples of technological advancements is the immense change in programming platforms. With a range of Application existing in the market for web application, PHP and Dot Net is considered as a leading and a highly accepted website development application technology. Basically PHP which is a scripting language which used to generate dynamic web pages which in turn bring interactivity with your users.


This language can also be written in HTML. But nowadays, PHP along with MY SQL is being used to construct some of the most powerful online databases.

 
Keeping in view the complex nature of PHP web development, hiring of highly skilled and experienced PHP developers becomes extremely crucial. Several benefits of hiring a PHP developer include reducing development cost since PHP also integrates with a number of open source applications like Joomla, Drupal, WordPress etc.


Being an open source technology it allows the user to make use of all platforms like Apache, Solaris, windows, Linux and various other platforms in order to take advantage of the investments made.
 
When you hire PHP developer you should care to find if he or she knows how effectively the XML is supported with 5th version. Now XML files work unified way and the efficiency of processing data has become compatible with W3C school specification. With SimpleXML in support 5th version has made parsing RSS files, REST results too much easy..


However it is also very important to note that in order to use PHP in an efficient way PHP tools are required. PHP tools are divided into different categories depending upon their functionality. For e.g. Webgrind is a debugging tool whereas PHP/SWF Charts is an outstanding tool for image manipulation and graphs.


If you are getting a website developed and you are confused in selecting the right programming language, have a look at your compatibility level. Moreover, Simple test is a testing and optimization tool while PHPE clipse runs on probably all major operating systems like Windows, Linux etc. While FirePHP is a data entry tool which helps to enter data in Firebug, Phing is a tool which can be utilized to do file transformations, run PHP Unit file system and CVS/SVN operations. Apart from that, if you need to connect the website with an existing application which has been developed on DOT net then you should select the same programming platform for web development purposes.
