WordPress plugin tutorial, wordpress plugin create table on activation, If you are making plugin and in plugin many times we need to create new tables. In this article I will show you how easily we can create the wordpress plugin.
wordpress plugin create table on activation
wordpress plugin create table on activation
Using following code you can create the table in wordpress database.
global $jal_db_version;
$jal_db_version = "1.0";
function jal_install () {
global $wpdb;
global $jal_db_version;
$table_name = $wpdb->prefix . "liveshoutbox";
if($wpdb->get_var("show tables like '$table_name'") != $table_name) {
$sql = "CREATE TABLE " . $table_name . " (
id mediumint(9) NOT NULL AUTO_INCREMENT,
time bigint(11) DEFAULT '0' NOT NULL,
name tinytext NOT NULL,
text text NOT NULL,
url VARCHAR(55) NOT NULL,
UNIQUE KEY id (id)
);";
require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($sql);
$rows_affected = $wpdb->insert( $table_name, array( 'time' => current_time('mysql'), 'name' => $welcome_name, 'text' => $welcome_text ) );
add_option("jal_db_version", $jal_db_version);
}
}
Now that we have the initialization function defined, we want to make sure that WordPress calls this function when the plugin is activated by a WordPress administrator. To do that, we will use the activate_ action hook. If your plugin file is wp-content/plugins/plugindir/pluginfile.php, you’ll add the following line to the main body of your plugin:
When you start writing post in wordpress panel. WordPress has facility to autosave the post with in every one minute. modify autosave Interval in wordpress.
how to modify autosave Interval in wordpress
how to modify autosave Interval in wordpress
When editing a post, WordPress uses Ajax to auto-save revisions to the post as you edit. You may want to increase this setting for longer delays in between auto-saves, or decrease the setting to make sure you never lose changes. The default is 60 seconds.
This really good feature of wordpress but sometimes this became very painful to blogger because of revision posts and size to database. Due to post revision wordpress post table size increases and Due to that database became slower.
So I recommend to change the auto save time of your wordpress.You can change the ‘auto-save’ time of wordpress blogs by your own time limit. This task invloves changin the configuration of AUTOSAVE_INTERVAL constant and replacing the given time interval by your time.
Just follow my steps very carefully. Open the wp-config.php file which you can find in your wordpress root folder.
and find the following sentence.
define('AUTOSAVE_INTERVAL', 60 ); // seconds
and change that to following
define('AUTOSAVE_INTERVAL', 180 ); // seconds
After doing this change upload wp-config.php file to server again. After this change Auto save will start after 3 min instead of 1 minute.
We all know what is excerpt. In wordpress using excerpt is good idea. WordPress provides the inbuild function called the_excerpt. Many people want to to show first few words on the theme front page. For that this function is very useful.
How to use the_excerpt in WordPress
How to use the_excerpt in WordPress
If you do not provide an explicit excerpt to a post (in the post editor’s optional excerpt field), it will display an automatic excerpt which refers to the first 55 words of the post’s content. Also in the latter case, HTML tags and graphics are stripped from the excerpt’s content.
Important Note: the_excerpt function must be written in The Loop.
For using the excerpt tag you need to put following code in the loop.
Some times you need to put excerpt tag conditionally. In archive or category and home page you want to show only the excerpt of post then you can use following code:
If you want to Control Excerpt Length using Filters use following code. To change excerpt length using excerpt_length filter, add the following code to functions.php file in your theme:
function new_excerpt_length($length) {
return 20;
}
add_filter('excerpt_length', 'new_excerpt_length');
use the_excerpt in WordPress
Tip: You can Remove […] string using Filters.By default, excerpt more string at the end is set to ‘[…]’. To change excerpt more string using excerpt_more filter, add the following code to functions.php file in your theme:
function new_excerpt_more($more) {
return '[.....]';
}
add_filter('excerpt_more', 'new_excerpt_more');
If you want to make read more link after excerpt then use following code:
function new_excerpt_more($more) {
global $post;
return '<a href="'. get_permalink($post->ID) . '">' . 'Read the Rest...' . '</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');
Many people faced memory issue wordpress and WordPress itself uses the so much memory. By default wordpress uses the 32mb memory. shown you to increase memory allocation for wordpress using config file.
increase memory allocation for wordpress
First you need to know what is the use of increasing the memory limit for wordpress. If I increase the WP_MEMORY_LIMIT from 32M to 64 or 96M will it make my website load fast.
We can adjust the amount of memory using the wp-config.php file.
define('WP_MEMORY_LIMIT', '96M');
Many shared hosting provides the default memory for php. What I see most commonly shared hosting set the memory limit to 8mb or 16mb. They does not allow you to increase the php memory limit and in that case if you changed the wp-config file then also there is no use of that change.
increase memory allocation for wordpress
What that setting do?
This setting increases PHP Memory only for WordPress, not other applications. By default, WordPress will attempt to increase memory allocated to PHP to 32MB (code is at beginning of wp-settings.php), so the setting in wp-config.php should reflect something higher than 32MB.

wordpress hooks are very important for wp developers. We can use the wp hooks in wordpress plugin and themes. Here in this article I will show you how to register the hook in wordpress plugin. I given the simple code sample which will give you the fare idea about using the wordpress hooks.
register activation hook using in wordpress plugin
register activation hook using in wordpress plugin
register_activation_hook is very important function for creating the wordpress plugin. The function register_activation_hook registers a plugin function to be run when the plugin is activated.
You can use the register_activation_hook as follows:
If you can going to create the wordpress simple plugin then this function is very useful. this function you can use as follows in files.
If you have a function called myplugin_activate() in the main plugin file at either
* wp-content/plugins/myplugin.php or
* wp-content/plugins/myplugin/myplugin.php
you can use code as follows:
global $myvar;
$myvar='whatever';
function myplugin_activate() {
global $myvar;
echo $myvar; // this will be 'whatever'
}
register_activation_hook( __FILE__, 'myplugin_activate' );
1. register_activation_hook() must be called from the main plugin file – the one that has “Plugin Name: …” directive.
2. Your hook function must be in the same file as well. From that function it is ok to call other functions defined in other files.
3. Doing echo “My hook called!”; – does not work from it. So this is not a good way to judge whether it working or not.
4. Your global variables must be explicitly declared as global for them to be accessed from inside of my_activation_hook().
Check the sample wordpress plugin code.
<!--?<span class="hiddenSpellError" pre="" data-mce-bogus="1"-->php
/*
Plugin Name: A Test
Description: A Test
*/
require_once (dirname(__FILE__) . '/my_other_file.php');
// This code *will not* work. Activation hook function must be defined in the main plugin file.
// register_activation_hook (dirname(__FILE__) . '/my_other_file.php', 'my_other_function');
// This code will work.
register_activation_hook (__FILE__, 'test_activated');
// This is correct way to declare/access globals.
global $some_var; // globals must be declared explicitly. Without this you will not be able to access '$some_var' from within 'test_activated()' function.
$some_var = 'hey';
//===========================================================================
function test_activated ()
{
global $some_var; // Now it will be 'hey'.
// This function is defined in 'my_other_file.php'
my_other_function ();
// This will not work, so don't try. If you need logging write something in temporary log file in here via fopen/fwrite.
// If you want to quickly test if your activation hook works - put exit() into it. At least you'll see error during activation.
echo 'test_activated called!';
}
//===========================================================================
?>
The function register_deactivation_hook registers a plugin function to be run when the plugin is deactivated.
following function will deactivate your plugin
